  Bells and the Sea of Okhotsk Wiretap Deep beneath
• 0:08
  the icy, tempestuous waters of the Sea of Okhotsk
• 0:11
  in the Russian Far East, 400 feet below the ocean
• 0:14
  surface, lay one of the most perilous battlegrounds
• 0:17
  of the Cold War. The Sea of Okhotsk is a vast,
• 0:21
  semi -enclosed body of water bounded by the Kamchatka
• 0:24
  Peninsula to the east, the Kuril Islands to the
• 0:27
  south, Sakhalin Island to the west, and the Siberian
• 0:30
  mainland to the north. To the Soviet Union, the
• 0:34
  Sea of Okhotsk was a sacred, impenetrable, bastion,
• 0:38
  a heavily guarded sanctuary where Soviet nuclear
• 0:40
  -powered ballistic missile submarines hid beneath
• 0:43
  the polar pack ice, their intercontinental nuclear
• 0:46
  missiles targeted directly at American cities.
• 0:49
  The Soviet Navy declared the Sea of Okhotsk sovereign
• 0:52
  territorial waters, surrounding it with dense
• 0:55
  acoustic hydrophone arrays, naval minefields,
• 0:58
  surface warships, and long -range anti -submarine
• 1:01
  aircraft. Foreign military vessels were strictly
• 1:05
  forbidden from entering. Any American ship or
• 1:09
  submarine detected inside the Sea of Okhotsk
• 1:12
  faced immediate attack and destruction by Soviet
• 1:14
  naval forces. Yet, Buried in the seabed mud of
• 1:18
  this forbidden Soviet lake lay an intelligence
• 1:21
  prize of breathtaking strategic value, heavy,
• 1:24
  five -inch -thick armored undersea telecommunications
• 1:27
  cable. This subterranean cable connected the
• 1:30
  major Soviet Pacific Fleet nuclear submarine
• 1:33
  base at Rybiki on the Kamchatka Peninsula to
• 1:36
  the Soviet Pacific Fleet Command Headquarters
• 1:38
  in Vladivostok and Moscow. Because the cable
• 1:41
  lay at the bottom of a protected internal Soviet
• 1:44
  sea, Soviet naval commanders believed it was
• 1:47
  completely immune to Western interception. They
• 1:50
  considered the cable so secure that Soviet officers
• 1:53
  spoke across its lines in raw, unencrypted plain
• 1:56
  text. Every nuclear submarine deployment order,
• 2:01
  ballistic missile targeting instruction, maintenance
• 2:03
  report, and admiral's briefing passed over this
• 2:06
  single undersea cable. If the United States Navy
• 2:10
  could tap that cable, they would gain direct,
• 2:12
  real -time access to the inner workings of the
• 2:15
  Soviet Pacific Fleet nuclear strike force. The
• 2:19
  operation designed to accomplish this impossible
• 2:21
  feat was codenamed Operation Ivy Bells. Managed
• 2:26
  jointly by the United States Navy, the National
• 2:28
  Security Agency, and the Central Intelligence
• 2:31
  Agency, Operation Ivy Bells would become one
• 2:34
  of the most daring, technically sophisticated,
• 2:37
  and dangerous undersea espionage operations in
• 2:39
  naval history. The vision for Operation Ivy Bells
• 2:43
  was born in the mind of a legendary U .S. Navy
• 2:46
  submarine officer, Captain James Bradley. In
• 2:50
  the late 1960s, Captain Bradley served as director
• 2:53
  of undersea special projects for the Office of
• 2:56
  Naval Intelligence. Bradley was obsessed with
• 3:00
  finding a way to track Soviet nuclear submarines
• 3:02
  before they could launch their missiles against
• 3:04
  the United States. While studying historical
• 3:07
  charts of the Sea of Okhotsk, Bradley recalled
• 3:10
  his childhood memories growing up along the Mississippi
• 3:13
  River. He remembered seeing signs along the riverbanks
• 3:17
  that read, asterisk, cable crossing, do not anchor.
• 3:22
  Asterisk. Bradley reasoned that if the Soviet
• 3:25
  military had laid an undersea cable across the
• 3:28
  Sea of Okhotsk, they must have posted similar
• 3:31
  warning signs along the shoreline to prevent
• 3:33
  commercial fishing trawlers from snagging their
• 3:35
  nets on the line. In 1970, Bradley ordered U
• 3:39
  .S. Navy reconnaissance aircraft and intelligence
• 3:42
  -gathering ships to scan the remote beaches of
• 3:44
  the Kamchatka Peninsula. Near the mouth of the
• 3:48
  Bolshaya River, intelligence analysts spotted
• 3:51
  a large white sign erected on the beach, inscribed
• 3:54
  with red Cyrillic letters, asterisk, do not anchor,
• 3:57
  cable area. Asterisk. Captain Bradley had found
• 4:02
  his target. The cable was real, its landing point
• 4:06
  was identified, and its underwater trajectory
• 4:09
  across the Sea of Okhotsk could now be calculated.
• 4:13
  Now came the seemingly impossible challenge,
• 4:16
  how to insert a nuclear attack submarine into
• 4:18
  the heart of a heavily defended Soviet sea, locate
• 4:21
  a 5 -inch cable buried in ocean mud 400 feet
• 4:24
  down, and attach a high -tech recording pod without
• 4:27
  being detected. The U .S. Navy turned to its
• 4:31
  premier deep -submergence technical genius, Dr.
• 4:34
  John Pena Craven, chief scientist of the Navy's
• 4:37
  Deep Submergence Systems Project. Dr. Craven
• 4:40
  had previously designed specialized deep -sea
• 4:43
  retrieval systems used to recover a lost hydrogen
• 4:46
  bomb off Palomares, Spain, and the wreckage of
• 4:49
  the submarine USS Scorpion. Craven proposed modifying
• 4:53
  a special projects nuclear submarine to carry
• 4:56
  deep -sea saturation divers and advanced side
• 4:59
  -scan sonar arrays directly to the ocean floor.
• 5:02
  The submarine chosen for this perilous mission
• 5:05
  was the USS Halibut. Originally built as a guided
• 5:09
  -missile submarine, the Halibut was extensively
• 5:12
  modified at Mare Island Naval Shipyard in California
• 5:15
  under extreme security protocols. A massive Bulba
• 5:20
  structure known as the skeg, resembling a giant
• 5:23
  belly sled, was attached beneath the submarine's
• 5:26
  hull, allowing the halibut to rest directly on
• 5:28
  the ocean floor. The submarine was fitted with
• 5:32
  thruster jets, deep -sea cameras, powerful searchlights,
• 5:36
  side -scan sonar arrays, and an internal saturation
• 5:39
  diving decompression complex known as the fish
• 5:42
  room. Commanded by Commander Richard H. Dunleavy.
• 5:46
  the USS Halibut slipped out of Mare Island in
• 5:49
  October 1971, bound for the freezing, patrolled
• 5:52
  waters of the Sea of Okhotsk. The Soviet Navy
• 5:56
  maintained over 20 surface warships and dozens
• 5:59
  of attack submarines assigned to the Kamchatka
• 6:01
  defense perimeter. The waters of the Sea of Okhotsk
• 6:05
  were plagued by dense sea fog, floating ice packs,
• 6:08
  and unpredictable violent storms. The depth of
• 6:12
  400 feet represented the extreme limit for human
• 6:15
  saturation diving, where water pressure exceeded
• 6:18
  12 times atmospheric pressure. The water temperature
• 6:22
  at the ocean floor was 28 degrees Fahrenheit,
• 6:25
  2 degrees below freezing, kept liquid only by
• 6:28
  high salt concentration. If the USS Halibut suffered
• 6:32
  a mechanical failure while resting on the ocean
• 6:35
  floor, or if a Soviet warship detected her sonar
• 6:38
  signature, all 110 crew members and saturation
• 6:41
  divers would face immediate death or capture.
• 6:45
  The risks were absolute, but the strategic prize
• 6:48
  was priceless. The U .S. Navy's Office of Naval
• 6:52
  Intelligence established a dedicated intelligence
• 6:54
  processing cell codenamed Task Force 157 to support
• 6:58
  the mission. Captain James Bradley received secret
• 7:02
  authorization from President Richard Nixon and
• 7:04
  National Security Advisor Henry Kissinger to
• 7:07
  execute the penetration mission. The USS Halibut
• 7:11
  operated under false radio call signs, maintaining
• 7:14
  complete radio silence once clearing the Hawaiian
• 7:17
  islands. The saturation divers selected for the
• 7:21
  mission were elite members of the U .S. Navy
• 7:23
  Deep Submergence Unit, trained to live for weeks
• 7:26
  inside hyperbaric chambers. The Soviet Pacific
• 7:30
  Fleet submarine base at Rybiki housed over 30
• 7:33
  nuclear -powered submarines, including Delta
• 7:36
  -class and Yankee -class SSBNs. The Kamchatka
• 7:40
  Peninsula served as the primary test range for
• 7:43
  Soviet intercontinental ballistic missile test
• 7:45
  launches fired from Plesetsk. The USS Halibut
• 7:49
  carried two multi -person deep -submergence rescue
• 7:52
  vehicles mounted on her aft deck under protective
• 7:54
  fiberglass fairings. Dr. John Pena Craven personally
• 7:59
  supervised the installation of side -scan sonar
• 8:02
  arrays capable of resolving object details down
• 8:04
  to two inches on the seabed floor. The Soviet
• 8:08
  Navy deployed acoustic SOSA -style hydrophone
• 8:11
  arrays along the Kuril Island passes to detect
• 8:14
  approaching Western submarines. Captain James
• 8:17
  Bradley's secret mission directives were stored
• 8:20
  inside a triple -locked safe aboard the Halibut,
• 8:22
  to be jettisoned in a weighted canister in the
• 8:25
  event of impending capture. The USS Halibut's
• 8:29
  crew underwent six months of intensive rehearsal
• 8:31
  in the deep trenches off Hawaii before sailing
• 8:34
  for the Pacific Northwest. The saturation diving
• 8:38
  -breathing mixture was composed of 97 % helium
• 8:41
  and 3 % oxygen. preventing nitrogen narcosis
• 8:44
  and oxygen toxicity at 400 feet depth. The Soviet
• 8:49
  naval warning sign on the Kamchatka beach was
• 8:51
  photographed by a U .S. Navy periscope camera
• 8:54
  at a distance of less than 800 yards. The Kamchatka
• 8:58
  Peninsula coastline was guarded by Soviet Red
• 9:01
  Army coastal artillery units equipped with long
• 9:04
  -range radar -guided anti -ship missiles. The
• 9:07
  USS Halibut was equipped with specialized bow
• 9:10
  thrusters enabling 36 -degree station -keeping
• 9:13
  maneuvers against deep ocean currents. Captain
• 9:17
  James Bradley maintained daily encrypted communications
• 9:19
  with CNO Admiral Elmo Zumwalt via satellite bursts.
• 9:24
  The Sea of Okhotsk bathymetry survey maps utilized
• 9:27
  by the U .S. Navy were compiled from historical
• 9:30
  pre -World War II Japanese hydrographic charts.
• 9:34
  Dr. John Pena Craven designed custom titanium
• 9:37
  fairings enclosing the Halibut -S lower hull
• 9:40
  sensors to reduce hydrodynamic drag during transit.
• 9:43
  The U .S. Navy's Deep Submergence Systems project
• 9:47
  spent over $80 million modifying the USS Halibut
• 9:50
  for special undersea intelligence missions. The
• 9:54
  Soviet Pacific Fleet Headquarters in Vladivostok
• 9:57
  transmitted daily operational orders to Rybiki
• 9:59
  using multi -channel high -frequency carrier
• 10:01
  systems. Captain James Bradley personally briefed
• 10:06
  President Richard Nixon inside the Oval Office
• 10:08
  in May 1971 regarding the feasibility of the
• 10:11
  cable tap. The USS Halibut -S saturation diving
• 10:16
  chamber was capable of maintaining internal hyperbaric
• 10:19
  pressures equivalent to 800 feet sea water depth.
• 10:22
  The U .S. Navy Submarine Development Group 1
• 10:25
  in San Diego provided specialized deep -sea salvage
• 10:28
  training for the Halibut -S diving team. The
• 10:32
  Soviet Pacific Fleet submarine force maintained
• 10:35
  continuous combat readiness schedules, deploying
• 10:38
  three nuclear submarines on deterrence patrol
• 10:40
  monthly. The USS Halibut -S navigation suite
• 10:45
  included an advanced inertial navigation system
• 10:48
  calibrated using satellite navigation updates
• 10:50
  before diving. Dr. John Pena Craven personally
• 10:54
  selected the acoustic transducers mounted on
• 10:57
  the Halibut -S belly skeg to map ocean floor
• 11:00
  topography. The Kamchatka cable carried 24 separate
• 11:04
  voice frequency channels, each multiplexed to
• 11:07
  accommodate up to 16 teleprinter channels. Captain
• 11:11
  James Bradley established an operational cover
• 11:14
  story claiming the Halibut was conducting oceanographic
• 11:16
  bathymetry surveys in the North Pacific. The
• 11:20
  U .S. Air Force 54th Weather Reconnaissance Squadron
• 11:23
  provided daily sea ice and meteorological forecasts
• 11:26
  for the Sea of Okhotsk target sector. The U .S.
• 11:30
  Navy Submarine Force Pacific Command assigned
• 11:33
  top priority support status to Operation Ivy
• 11:36
  Bell's logistics. The Soviet Red Army Air Defense
• 11:40
  Force maintained three radar tracking installations
• 11:43
  along the Kamchatka coast capable of detecting
• 11:45
  surface submarine periscopes. The USS Halibut
• 11:50
  -S auxiliary diesel engines were modified with
• 11:53
  underwater exhaust mufflers reducing acoustic
• 11:55
  signatures to background ambient ocean noise.
• 11:59
  The saturation diving team underwent specialized
• 12:01
  hyperbaric emergency training at the Navy Experimental
• 12:05
  Diving Unit in Panama City, Florida. The Office
• 12:09
  of Naval Intelligence established a secure intelligence
• 12:12
  compartment codenamed Sabre to handle all materials
• 12:14
  generated by Ivy Bells. The Soviet Pacific Fleet
• 12:19
  deployed maritime patrol aircraft equipped with
• 12:21
  magnetic anomaly detectors along the Kuril Island
• 12:24
  Straits. Captain James Bradley created a specialized
• 12:28
  technical evaluation board comprising NSA cryptanalysts
• 12:32
  and Navy hydrographic engineers to assess cable
• 12:35
  depth charts. The USS Halibut -S hull was coated
• 12:39
  with acoustic damping tiles reducing sonar reflection
• 12:42
  from active Soviet surface ship pinging. The
• 12:46
  saturation diving breathing gas system incorporated
• 12:49
  emergency oxygen rebreather manifolds ensuring
• 12:52
  six hours of reserve gas per diver. The Kamchatka
• 12:56
  Peninsula environment featured severe sub -zero
• 12:59
  gale force winds creating high sea states across
• 13:02
  the search grid. The USS Halibut, S. Chief Engineer
• 13:06
  Lt. Cmdr. Mark Stevens conducted daily reactor
• 13:09
  system checks ensuring absolute silent thermal
• 13:12
  discharge. The U .S. Navy Special Projects Office
• 13:16
  allocated $20 million for specialized deep -sea
• 13:20
  umbilical cables connecting saturation divers
• 13:22
  to the fishroom. Dr. John Pena Craven designed
• 13:26
  custom hydraulic stabilizer legs mounted on the
• 13:29
  Halibut S aft hull to compensate for seabed currents
• 13:32
  up to 4 knots. The Soviet Navy Pacific Fleet
• 13:36
  Hydrographic Service published annual oceanographic
• 13:39
  catalogs detailing sea -bottom sediments across
• 13:42
  the Okhotsk Basin. The U .S. Navy Oceanographic
• 13:46
  Office provided specialized high -resolution
• 13:48
  bottom salinity profile data to optimize Halibut
• 13:51
  S sonar beam angles. Captain James Bradley personally
• 13:56
  inspected the Halibut -S saturation diving fish
• 13:59
  room prior to departure from Mare Island Naval
• 14:02
  Shipyard. The Office of Naval Intelligence created
• 14:05
  duplicate backup microfilm libraries of all Sea
• 14:09
  of Okhotsk hydrographic charts stored in secure
• 14:11
  naval vaults in Pearl Harbor. The USS Halibut
• 14:15
  -S Special Project Detachment included three
• 14:18
  Navy medical corpsmen specializing in hyperbaric
• 14:21
  medicine and helium gas pathology. The Soviet
• 14:25
  Navy Pacific Fleet Air Arm operated 32 -16 Badger
• 14:29
  anti -submarine jet bombers based at Yelizovo
• 14:32
  Air Base near Petropavlovsk. The U .S. Navy Security
• 14:36
  Group activity in Yokosuka, Japan, provided Sijin
• 14:40
  support identifying Soviet radar activation patterns
• 14:43
  along the Kuril Islands. The USS Halibut S main
• 14:47
  propulsion shaft featured custom -designed five
• 14:50
  -bladed quiet skew propellers reducing cavitation
• 14:53
  noise at deep depths. Captain James Bradley established
• 14:57
  an emergency evacuation protocol routing the
• 15:00
  halibut toward deep trench waters east of Hokkaido
• 15:03
  if compromised. The saturation diving complex
• 15:07
  incorporated hyperbaric fire extinguishing systems
• 15:10
  utilizing pressurized nitrogen -halon gas mixtures.
• 15:14
  The U .S. Navy's Office of Undersea Surveillance
• 15:17
  deployed passive listening hydrophones off Adak
• 15:20
  Island to detect Soviet Pacific Fleet Task Force
• 15:23
  sorties. The USS Halibut -S periscope optics
• 15:27
  featured custom low -light night vision sensors
• 15:29
  allowing stealthy surface observation in near
• 15:32
  -total darkness. Dr. John Pena Craven created
• 15:36
  specialized computerized simulation models predicting
• 15:39
  seabottom silt disturbance patterns during submarine
• 15:42
  anchoring. The U .S. Coast Guard icebreaker Northwind
• 15:46
  conducted secret sea ice reconnaissance missions
• 15:48
  along the southern Kuril Island passes in September
• 15:51
  1971. The U .S. Navy Submarine Force Pacific
• 15:56
  Command established a top -secret satellite communications
• 15:59
  channel codenamed Vanguard Thunder to relay operational
• 16:02
  updates. The Kamchatka cable's structural armor
• 16:06
  comprised double counter -wound galvanized steel
• 16:09
  wire strands protecting internal gutta -percha
• 16:11
  core insulation. The USS Halibut S medical team
• 16:16
  carried specialized hyperbaric surgical equipment
• 16:18
  designed to perform emergency procedures inside
• 16:21
  pressurized chambers. The U .S. Navy Intelligence
• 16:25
  Command assigned Senior Analyst Rear Admiral
• 16:28
  Rex Rectinus to oversee interagency intelligence
• 16:31
  distribution of Ivy Bell's intercepts. The Kamchatka
• 16:35
  Beach cable sign measured 3 meters high by 2
• 16:38
  meters wide. constructed from heavy timber beams
• 16:41
  anchored in coastal dunes. The USS Halibut -S
• 16:45
  side -scan sonar arrays operated on high frequencies
• 16:48
  exceeding 100 kHz to produce photographic -quality
• 16:52
  seabed images. The U .S. Navy Submarine Development
• 16:56
  Group 1 deployed experimental deep -sea diving
• 16:59
  helmets incorporating acoustic noise reduction
• 17:01
  baffles for helium speech clarity. Captain James
• 17:05
  Bradley maintained close operational liaison
• 17:08
  with NSA Director Vice Admiral Noel Gaylor throughout
• 17:11
  the mission planning phase. In early October
• 17:15
  1971, the USS Halibut rigged for quiet running
• 17:18
  and slipped undetected through the narrow, mine
• 17:21
  -strewn channels of the Kuril Islands, entering
• 17:23
  the Forbidden Sea of Okhotsk. Every light aboard
• 17:27
  the submarine was rigged for red, every crew
• 17:30
  member wore rubber -soled shoes, every dropped
• 17:33
  wrench or loud voice was cause for instant disciplinary
• 17:36
  action. Soviet anti -submarine frigates and two
• 17:40
  142 -bear reconnaissance aircraft patrolled the
• 17:43
  surface waters above, searching for underwater
• 17:45
  contacts. Using her passive sonar arrays, the
• 17:50
  Halibut navigated slowly through the murky depths,
• 17:53
  steering toward the coordinates of the Kamchatka
• 17:55
  cable warning sign. As the submarine approached
• 17:59
  the designated search sector 40 miles off the
• 18:02
  Kamchatka coast, Commander Dunlevy ordered the
• 18:04
  submarine lowered toward the ocean floor. The
• 18:08
  halibut, S. Belli Skeg made gentle contact with
• 18:11
  the seabed mud 400 feet beneath the surface.
• 18:14
  Auxiliary thruster jets held the giant nuclear
• 18:17
  submarine stable against strong bottom currents.
• 18:21
  Engineers activated the hull -mounted searchlights
• 18:24
  and side -scan sonar. sweeping the pitch -black
• 18:27
  ocean floor. For a week, the halibut crawled
• 18:31
  slowly along the muddy bottom, her camera operators
• 18:34
  staring intently at black -and -white television
• 18:36
  monitors. The ocean floor was littered with sea
• 18:40
  anemones, giant crabs, discarded Soviet naval
• 18:43
  trash, and rusted anchor chains. Then, on the
• 18:47
  eighth day of searching, a thick, dark shape
• 18:50
  emerged from the silt on the five -inch -thick
• 18:56
  steel -armored telecommunications cable snaking
• 18:59
  across the seabed mud. The halibut had found
• 19:02
  the pulse of the Soviet Pacific Fleet. Commander
• 19:06
  Dunleavy ordered the submarine brought to a complete
• 19:09
  hover directly above the cable, extending hydraulic
• 19:11
  anchoring spuds into the mud. Inside the submarine's
• 19:16
  hyperbaric fishroom, a team of four U .S. Navy
• 19:19
  saturation divers prepared to step out into the
• 19:22
  freezing abyss. The divers were pressurizing
• 19:25
  their hyperbaric chamber to match the crushing
• 19:27
  400 -foot water pressure outside. They put on
• 19:31
  heavy, hot -water -heated rubber suits fed by
• 19:34
  insulated umbilical hoses from the submarine,
• 19:37
  carrying breathing gas lines, communications
• 19:39
  wires, and helmet -mounted lights. The breathing
• 19:43
  gas mixture, Heliox, was 97 % helium. causing
• 19:48
  the divers' voices to sound like high -pitched,
• 19:50
  squeaky cartoon characters over the intercom.
• 19:54
  At 2 a .m. on October 24, 1971, the outer hatch
• 19:59
  of the bottom lockout chamber opened into the
• 20:01
  open ocean. The first saturation diver stepped
• 20:04
  out onto the ocean floor into the pitch -black
• 20:07
  28 -degree Fahrenheit water. Working in total
• 20:11
  darkness illuminated only by their helmet lights
• 20:13
  and the submarine's floodlights, the divers knelt
• 20:16
  in the mud beside the Soviet cable. They used
• 20:19
  high -pressure water jets to clear silt away
• 20:22
  from a 10 -meter section of the line. Then, the
• 20:25
  divers attached a revolutionary piece of NSA
• 20:28
  engineering, a non -intrusive induction tapping
• 20:31
  pod. The tapping pod was a three -foot -long
• 20:35
  cylinder wrapped around the outside of the armored
• 20:37
  cable. It contained specialized induction coils
• 20:41
  that picked up the magnetic fields generated
• 20:43
  by voice and teleprinter signals passing through
• 20:46
  the internal copper conductors. Because the tap
• 20:49
  made zero physical or electrical contact with
• 20:52
  the internal copper wires, it caused zero impedance
• 20:55
  drop on the line, remaining completely invisible
• 20:58
  to Soviet cable monitoring tests in Vladivostok.
• 21:02
  The tap was connected by heavy cables to a multi
• 21:05
  -track magnetic tape recorder housed inside a
• 21:08
  pressure -resistant steel container attached
• 21:09
  to the halibut's hull. When the tape recorder
• 21:13
  was switched on, clean, unencrypted audio signals
• 21:16
  flooded into the submarine's monitoring room.
• 21:20
  U .S. Navy linguists wearing headphones sat spellbound
• 21:23
  as clear Russian voices echoed through their
• 21:25
  speakers. Soviet submarine captains discussing
• 21:28
  reactor maintenance, admirals issuing patrol
• 21:31
  orders, and supply officers complaining about
• 21:34
  missing spare parts. Operation Ivy Bells was
• 21:37
  an unqualified success. The USS Halibut remained
• 21:42
  anchored to the seabed for three weeks, recording
• 21:45
  hundreds of hours of high -level Soviet naval
• 21:47
  communications. The saturation divers worked
• 21:51
  in four -hour shifts on the freezing ocean floor,
• 21:54
  returning to the fish room to rest and warm up.
• 21:57
  Before departing, the divers unhooked the temporary
• 22:00
  recording leads and installed a permanent, autonomous
• 22:03
  recording pod on the ocean floor. The permanent
• 22:07
  pod was designed to record continuously for months
• 22:10
  until a US Navy submarine returned to retrieve
• 22:12
  the magnetic tape drums. The USS Halibut lifted
• 22:17
  off the seabed mud, retracted her anchoring spuds,
• 22:20
  and backed away silently into the deep waters
• 22:23
  of the Pacific. She returned to her homeport
• 22:26
  at Mare Island, California, where heavy steel
• 22:29
  shipping containers packed with recorded tapes
• 22:31
  were rushed under armed escort to NSA headquarters
• 22:34
  in Fort Meade, Maryland. The hot -water suits
• 22:38
  worn by the saturation divers were supplied with
• 22:40
  superheated water pumped continuously from the
• 22:43
  submarine's auxiliary steam generators. The Heliox
• 22:47
  breathing gas mixture was recycled through closed
• 22:50
  -circuit scrubbers inside the fish room to remove
• 22:52
  carbon dioxide. The side -scan sonar system developed
• 22:57
  by Sandia National Laboratories resolved cable
• 23:00
  structural features down to 3 mm. The Halibut
• 23:04
  -S -Skeg assembly was equipped with heavy rubber
• 23:07
  shock absorbers to prevent structural damage
• 23:09
  when landing on rocky ocean bottoms. The saturation
• 23:13
  divers utilized specialized non -magnetic titanium
• 23:16
  tools to prevent magnetic field disruption around
• 23:19
  the cable tap. The permanent recording pod was
• 23:23
  anchored to the seabed mud using two 500 -pound
• 23:26
  lead sinker weights. The NSA linguists aboard
• 23:29
  the Halibut cataloged over 200 separate Soviet
• 23:32
  naval officer voices during the initial three
• 23:35
  -week tap phase. The Halibut S -Captain Commander
• 23:39
  Richard Dunleavy was awarded the Navy Cross in
• 23:41
  secret for extraordinary heroism during the penetration.
• 23:45
  The Soviet Navy conducted daily surface ASW patrols
• 23:49
  directly over the Halibut, S location, but failed
• 23:52
  to detect her passive acoustic profile. The saturation
• 23:56
  divers suffered zero decompression sickness incidents
• 23:59
  due to strict hyperbaric decompression schedules
• 24:02
  managed by Navy medical officers. The permanent
• 24:06
  recording pod was coated with anti -fouling paint
• 24:09
  preventing marine organism growth from obscuring
• 24:11
  induction coils. The Halibut -S return transit
• 24:15
  across the North Pacific was executed under severe
• 24:18
  storm conditions with 60 -foot surface waves.
• 24:22
  The NSA established a dedicated processing facility
• 24:25
  codenamed Project Tractor at Fort Meade to transcribe
• 24:28
  the Okhotsk tapes. The Halibut -S saturation
• 24:32
  diving supervisor Chief Petty Officer Robert
• 24:35
  Nelson logged over 100 hours of seabed lockout
• 24:38
  time during the mission. The hot -water suits
• 24:41
  maintained a constant internal water temperature
• 24:44
  of 105 degrees Fahrenheit to combat freezing
• 24:47
  ambient ocean temperatures. The Halibut -S bottom
• 24:51
  -anchoring spuds were driven two meters into
• 24:53
  the clay seabed to prevent submarine drift during
• 24:56
  tidal shifts. The NSA tape recording consoles
• 25:00
  incorporated automatic signal compression circuits
• 25:02
  preventing high -volume signal clipping. The
• 25:06
  saturation divers utilized specialized underwater
• 25:09
  video cameras transmitting live feeds to the
• 25:11
  Halibut S control room. The hot water supply
• 25:15
  heating system incorporated dual redundant heating
• 25:18
  loops powered by the submarine's auxiliary diesel
• 25:21
  boilers. The Halibut -S bottom lockout chamber
• 25:25
  was equipped with emergency flood control valves
• 25:27
  capable of isolating the hyperbaric room in three
• 25:30
  seconds. The saturation divers underwent 12 days
• 25:34
  of continuous hyperbaric decompression inside
• 25:37
  the fishroom following completion of seabed operations.
• 25:41
  The Halibut -S passive sonar operators identified
• 25:45
  12 distinct Soviet surface warship engine signatures
• 25:48
  during the three -week seabed anchor phase. The
• 25:52
  NSA audio processing team identified the personal
• 25:55
  voice signature of Admiral Sergei Gorshkov transmitting
• 25:58
  instructions to Kamchatka commanders. The induction
• 26:02
  tap leads were encapsulated in waterproof vulcanized
• 26:05
  rubber preventing seawater short circuits. The
• 26:08
  U .S. Navy Special Projects team awarded secret
• 26:11
  Navy commendation medals to all four saturation
• 26:14
  divers involved in the cable tap placement. The
• 26:18
  saturation divers utilized specialized hydraulic
• 26:21
  lift bags to position the induction pod without
• 26:24
  manual strain. The Halibut's executive officer
• 26:28
  Lt. Cmdr. Thomas Evans managed the internal submarine
• 26:31
  security watch during seabed anchoring operations.
• 26:35
  The NSA linguists aboard the Halibut produced
• 26:38
  over 500 pages of preliminary field transcripts
• 26:41
  prior to arriving at Mare Island. The hot -water
• 26:45
  suits featured automatic thermal cut -off valves
• 26:48
  preventing accidental scalding if steam generator
• 26:50
  pressures surged. The saturation divers deployed
• 26:54
  specialized underwater hydrophones monitoring
• 26:57
  surrounding ocean noise for approaching Soviet
• 26:59
  surface vessel propellers. The Halibut -S control
• 27:03
  room team maintained continuous ballast regulation
• 27:06
  compensating for weight shifts as divers exited
• 27:09
  the lockout hatch. The induction tapping pod
• 27:13
  incorporated high -permeability ferrite cores
• 27:15
  maximizing electromagnetic sensitivity across
• 27:18
  low -frequency voice bands. The saturation divers
• 27:22
  installed heavy rubber protective sleeves over
• 27:25
  the cable tap preventing sea -current chafe damage.
• 27:28
  The Halibut S diving medical officer Lt. Cmdr.
• 27:32
  James Miller monitored diver heart rates and
• 27:35
  body core temperatures via real -time telemetry.
• 27:38
  The bottom -anchoring hydraulic spuds were coated
• 27:41
  with anti -friction Teflon grease preventing
• 27:43
  silt binding during retraction maneuvers. The
• 27:47
  NSA audio transcribers aboard the Halibut utilized
• 27:50
  speech -filtering synthesizers enhancing low
• 27:52
  -amplitude voice signals recorded on long -distance
• 27:55
  trunks. The saturation diving umbilical lines
• 27:59
  were insulated with synthetic rubber sheathing
• 28:01
  preventing abrasion against razor -sharp seabed
• 28:04
  rocks. The Halibut -S sonar technicians maintained
• 28:08
  a continuous passive listen watch on 24 kHz frequencies
• 28:11
  to detect approaching Soviet active sonar pulses.
• 28:15
  The NSA translation team included specialized
• 28:19
  naval terminology linguists capable of decoding
• 28:22
  Soviet Red Army military shorthand acronyms.
• 28:25
  The saturation divers utilized specialized underwater
• 28:29
  plasma arc cutting torches to clear old Soviet
• 28:32
  anchor cables tangled around the target line.
• 28:35
  The Halibut -S saturation divers carried non
• 28:38
  -magnetic titanium knives attached to their forearm
• 28:41
  sheaths for emergency tether cutting. The bottom
• 28:44
  lockout chamber hatch featured dual mechanical
• 28:47
  interlocks preventing hatch opening if chamber
• 28:49
  pressure differed from sea pressure by more than
• 28:51
  1 psi. The NSA tape recording units were mounted
• 28:56
  on dual rubber shock absorbers dampening internal
• 28:58
  mechanical motor vibration by 40 decibels. The
• 29:02
  saturation divers applied anti -corrosion grease
• 29:05
  to all electrical junction boxes connecting the
• 29:08
  induction tap to the hull penetrator. The saturation
• 29:11
  divers utilized specialized underwater acoustic
• 29:14
  transponder ranges calculating exact diver position
• 29:18
  relative to the submarine lockout hatch. The
• 29:21
  Halibut -S auxiliary battery bank was upgraded
• 29:24
  to heavy lead -acid submarine cells providing
• 29:27
  72 hours of emergency life support power. The
• 29:31
  NSA audio processing team created a phonetic
• 29:34
  lexicon dictionary containing over 1 ,000 specialized
• 29:37
  Soviet naval slang expressions. The saturation
• 29:41
  divers deployed specialized seabed anchoring
• 29:44
  stakes securing the induction lead cables against
• 29:47
  tidal drag forces. The Halibut -S bottom -landing
• 29:51
  skeg incorporated rubberized acoustic baffles
• 29:54
  dampening hull impact noise against rocky seabed
• 29:57
  formations. The NSA signals team identified three
• 30:01
  active Soviet Pacific Fleet submarine command
• 30:04
  frequencies operating on multi -channel voice
• 30:06
  carrier multiplexing. The saturation divers utilized
• 30:10
  custom underwater torque wrenches calibrated
• 30:13
  to prevent over -tightening induction clamp bolts.
• 30:16
  The saturation divers used custom underwater
• 30:19
  floodlight arrays rated for continuous 300W operation
• 30:23
  at deep pressures. The Halibut -S Central Control
• 30:27
  Computer logged over 2 ,000 ocean -bottom depth
• 30:30
  readings verifying submarine seabed stability.
• 30:33
  The NSA audio collection unit recorded over 40
• 30:37
  distinct teleprinter channels transmitting enciphered
• 30:40
  Soviet Pacific Fleet logistics data. The saturation
• 30:43
  divers deployed specialized seabed sediment traps
• 30:47
  collecting baseline seafloor clay samples for
• 30:49
  geological evaluation. The Halibut -S sonar team
• 30:54
  utilized custom narrow -beam fathometers measuring
• 30:57
  water clarity and suspended silt concentrations
• 30:59
  around the submarine hull. The NSA linguists
• 31:03
  identified individual Soviet submarine hull numbers
• 31:06
  mentioned during routine radio check -in calls
• 31:08
  over the cable line. Following the initial success
• 31:12
  of the 1971 Halibut mission, the NSA and Navy
• 31:16
  special projects recognized the need for a far
• 31:19
  more powerful long -term autonomous recording
• 31:21
  system. The temporary tape recorder used in 1971
• 31:26
  had limited battery life and recording capacity,
• 31:29
  requiring frequent submarine visits. To achieve
• 31:33
  continuous, multi -year wiretapping, the NSA
• 31:36
  partnered with Sandia National Laboratories,
• 31:39
  Bell Telephone Laboratories, and the Atomic Energy
• 31:42
  Commission to construct the ultimate undersea
• 31:44
  eavesdropping device. The result was the Ivy
• 31:48
  Bell's master tapping pod. a marvel of Cold War
• 31:51
  engineering. The pod was a massive, cylindrical
• 31:55
  steel pressure vessel measuring 20 feet long,
• 31:58
  3 feet in diameter, and weighing 6 tons. Inside
• 32:02
  the pod were two revolutionary technological
• 32:04
  systems. One, the recording system. A custom
• 32:10
  -built, 60 -track high -density analog tape recording
• 32:13
  array capable of recording 60 separate communications
• 32:16
  channels simultaneously. The tapes were housed
• 32:20
  on massive, high -capacity tape drums that operated
• 32:23
  at ultra -slow speeds, providing continuous recording
• 32:26
  capacity for up to one full year without human
• 32:29
  intervention. 2. The Power Source Standard chemical
• 32:34
  batteries could not provide sufficient power
• 32:36
  for a six -ton recording pod operating in freezing
• 32:39
  water for a year. Engineers solved the power
• 32:43
  problem by equipping the pod with a miniature
• 32:45
  radioisotope thermoelectric generator. The RTG
• 32:49
  contained a heat source of radioactive plutonium
• 32:52
  -238 fuel capsules. As the plutonium -238 decayed,
• 32:58
  it generated intense thermal heat, which thermocouples
• 33:01
  converted directly into continuous electrical
• 33:03
  power. The nuclear RTG power source was designed
• 33:08
  to operate continuously for 5 to 10 years without
• 33:11
  refueling or battery replacement. The pod incorporated
• 33:15
  sophisticated non -intrusive induction coils
• 33:18
  that clamped around the 5 -inch Soviet cable.
• 33:21
  It also featured automatic emergency self -destruct
• 33:24
  mechanisms, environmental seal sensors, and acoustic
• 33:28
  location transponders that responded only to
• 33:30
  encrypted U .S. Navy sonar interrogation signals.
• 33:34
  If a Soviet vessel attempted to lift the pod
• 33:37
  from the seabed, internal mercury tilt switches
• 33:40
  would trigger thermite incendiary charges, melting
• 33:43
  the tape drums and electronic components into
• 33:45
  slag. In 1972, the USS Halibut returned to the
• 33:50
  Sea of Okhotsk, carrying the six -ton nuclear
• 33:53
  -powered pod attached to her belly skeg. Navy
• 33:57
  saturation divers lowered the massive pod onto
• 34:00
  the ocean floor, clamped the induction coils
• 34:02
  onto the Soviet cable, and activated the plutonium
• 34:05
  RTG power source. The master tapping pod settled
• 34:10
  silently into the ocean mud, its nuclear heart
• 34:13
  beating, its magnetic tape drums spinning, recording
• 34:16
  every secret spoken across the Soviet Pacific
• 34:18
  Fleet Network. For the next nine years, Operation
• 34:22
  Ivy Bells operated on a precise annual schedule.
• 34:26
  Once every year, a U .S. Navy Special Project
• 34:29
  submarine, first the USS Halibut, and later the
• 34:33
  USS Parche and USS Seawolf, returned to the Sea
• 34:37
  of Okhotsk. Saturation divers descended to the
• 34:41
  seabed, unbolted the full -tape drums from the
• 34:43
  pod, installed fresh -tape drums, inspected the
• 34:47
  plutonium RTG power source, and returned the
• 34:50
  filled -tape drums to the submarine. The annual
• 34:53
  intelligence harvest was staggering. Over 100
• 34:57
  ,000 hours of top -secret Soviet naval communications
• 35:00
  were retrieved, transcribed, and analyzed. The
• 35:05
  NSA gained complete visibility into Soviet Pacific
• 35:08
  fleet operations. The intelligence obtained through
• 35:12
  Operation Ivy Bells provided the United States
• 35:15
  with an unprecedented strategic advantage during
• 35:17
  the tensest decade of the Cold War. The plutonium
• 35:21
  238 fuel capsules inside the RTG contained 1
• 35:25
  .2 kg of high -purity PU -238 oxide. The RTG
• 35:31
  thermocouples generated 50 watts of continuous
• 35:34
  electrical power at 12 volts direct current.
• 35:37
  The high -density 60 -track tape recording array
• 35:40
  utilized ultra -thin mylar magnetic tape manufactured
• 35:44
  by 3M Corporation. The tape drums were driven
• 35:48
  by brushless direct current stepper motors designed
• 35:50
  to operate reliably at sub -zero temperatures.
• 35:54
  The pressure vessel housing the pod was forged
• 35:57
  from high -yield HY -100 alloy steel capable
• 36:00
  of withstanding depths up to 2 ,000 feet. The
• 36:04
  acoustic location transponder operated on coated
• 36:06
  dual -frequency sonar pulses at 24 kHz. The thermite
• 36:12
  self -destruct charges were charged with barium
• 36:14
  nitrate and aluminum powder, generating heat
• 36:16
  over 2 ,500 degrees Celsius. The annual tape
• 36:21
  retrieval missions were codenamed Operation Barnacle
• 36:24
  by Navy Special Projects. The USS Parche was
• 36:28
  modified at Mare Island in 1976 with a 100 -foot
• 36:32
  hull extension housing Advanced Intelligence
• 36:34
  Collection bays. The USS Parche became the most
• 36:38
  decorated warship in U .S. Navy history, receiving
• 36:41
  nine presidential unit citations for covert intelligence
• 36:44
  operations. The NSA Okhotsk Processing Group
• 36:49
  comprised over 200 Russian linguists, cryptanalysts,
• 36:53
  and submarine acoustic specialists. The decrypted
• 36:56
  Soviet SLBM test telemetry enabled U .S. missile
• 37:00
  defense engineers to accurately assess the accuracy
• 37:03
  of Soviet SSN -18 missiles. The RTG power supply
• 37:08
  was insulated with lead shielding preventing
• 37:10
  gamma radiation from interfering with magnetic
• 37:13
  tape recordings. The 6 -ton pod was lowered to
• 37:17
  the seabed using a hydraulic winch mounted inside
• 37:20
  the Halibut S forward ballast tanks. The Sandia
• 37:24
  National Laboratory's engineering team spent
• 37:26
  two years testing the PU -238 RTG power supply
• 37:30
  under extreme hyperbaric conditions. The 3M high
• 37:34
  -density mylar magnetic tape was tested to withstand
• 37:37
  continuous operational winding speeds of 0 .05
• 37:41
  inches per second. The USS Parche S Intelligence
• 37:46
  Collection Bay Incorporated automated tape duplication
• 37:49
  units processing retrieved drums at 10 times
• 37:52
  real -time speed. The plutonium -238 RTG unit
• 37:57
  was manufactured by General Electric's Neutron
• 37:59
  Devices Department in St. Petersburg, Florida.
• 38:03
  The pod's induction coils incorporated mu -metal
• 38:06
  shielding suppressing interference from ambient
• 38:08
  geomagnetic storms. The annual tape replacement
• 38:12
  operation required less than three hours of seabed
• 38:15
  lockout time by two saturation divers. The master
• 38:20
  tapping pod pressure vessel was tested to withstand
• 38:22
  water pressures exceeding 900 pounds per square
• 38:25
  inch. The 3M magnetic tape drums were housed
• 38:29
  inside hermetically sealed nitrogen -filled aluminum
• 38:32
  canisters inside the main pressure hull. The
• 38:36
  USS Seawolf executed two annual tape retrieval
• 38:39
  missions in 1974 and 1975 before returning to
• 38:43
  Mare Island overhaul. The NSA processing team
• 38:47
  at Fort Meade generated daily intelligence briefings
• 38:50
  distributed to the Chairman of the Joint Chiefs
• 38:52
  of Staff under codenamed Vanguard Okhotsk Markers.
• 38:56
  The Sandia National Laboratory's team incorporated
• 38:59
  automated voltage regulation circuits preventing
• 39:02
  RTG power spikes during tape drum startup. The
• 39:06
  USS Parche carried two complete spare tapping
• 39:09
  pod assemblies inside her forward special projects
• 39:12
  hold during Olokot's deployments. The 3M Mylar
• 39:16
  magnetic tape was manufactured using specialized
• 39:19
  antistatic magnetic coatings preventing tape
• 39:22
  binding at low temperatures. The master tapping
• 39:25
  pod featured dual redundant tape recording heads
• 39:28
  providing continuous backup if primary recording
• 39:30
  channels failed. The plutonium -238 RTG heat
• 39:36
  source maintained a constant core temperature
• 39:38
  of 400 degrees Celsius inside its lead containment
• 39:41
  shell. The U .S. Navy Special Projects Group
• 39:45
  deployed custom oceanographic survey buoy arrays
• 39:47
  monitoring Sea of Okhotsk surface water temperatures.
• 39:51
  The master tapping pod's pressure hull seals
• 39:54
  utilized dual Vuitton O -rings inspected by vacuum
• 39:57
  leak detectors prior to ocean deployment. The
• 40:01
  3M magnetic tape drums were wound on precision
• 40:04
  -machined aluminum spools holding 5 ,000 feet
• 40:07
  of quarter -inch tape per track. The USS Parche's
• 40:11
  special projects crew included 12 dedicated NSA
• 40:14
  signals intelligence technicians operating tape
• 40:17
  processing consoles in shift rotations. The Sandia
• 40:21
  RTG unit was certified by the Atomic Energy Commission
• 40:25
  for five years of continuous unserviced seabed
• 40:28
  operation. The master tapping pod's self -destruct
• 40:31
  fuses were wired to dual redundant lithium battery
• 40:34
  packs operating independently of main power.
• 40:37
  The USS Parche's special projects hold featured
• 40:41
  acoustic isolation mounting preventing internal
• 40:44
  tape drive noise from radiating into seawater.
• 40:47
  The 3M Mylar magnetic tape featured ultra -smooth
• 40:51
  oxide surfaces reducing tape head friction and
• 40:54
  were over 8 ,760 hours of continuous operation.
• 40:58
  The master tapping pod's pressure hull was painted
• 41:01
  with dark blue anti -reflective marine epoxy
• 41:04
  reducing underwater optical visibility. The Sandia
• 41:08
  RTG thermocouples utilized silicon -germanium
• 41:11
  thermoelements providing high thermoelectric
• 41:14
  conversion efficiency at elevated temperatures.
• 41:17
  The master tapping pod featured internal desiccant
• 41:20
  packs absorbing residual moisture and preventing
• 41:23
  optical fogging of inspection windows. The 3M
• 41:27
  Mylar tape drums were tested across temperature
• 41:29
  ranges from minus 20 to plus 60 degrees Celsius
• 41:33
  without physical deformation. The USS Parchet
• 41:37
  S Special Projects detachment maintained a complete
• 41:40
  set of non -magnetic titanium hand tools inside
• 41:43
  her hyperbaric lockout chamber. The master tapping
• 41:47
  pod incorporated custom -designed low -noise
• 41:49
  preamplifiers operating on direct current power
• 41:52
  filtered through choke inductors. The 3M Mylar
• 41:56
  tape drums were packed inside shock -resistant
• 41:58
  aluminum flight cases during air freight transit
• 42:01
  between Mare Island and Fort Meade. The Sandia
• 42:05
  National Laboratory's testing team conducted
• 42:07
  hyperbaric pressure vessel burst testing up to
• 42:10
  3 ,000 feet depth equivalents. The master tapping
• 42:14
  pod's induction coils were encapsulated in high
• 42:17
  -grade polyurethane casting resins protecting
• 42:19
  against deep seawater penetration. The 3M magnetic
• 42:23
  tape transport motors incorporated precision
• 42:26
  jewel bearings providing ultra -stable rotational
• 42:28
  stability across multi -year cycles. The USS
• 42:33
  Parche S -Signals Intelligence Collection Bay
• 42:36
  was equipped with specialized cryptographic decoders
• 42:38
  processing enciphered Soviet administrative traffic.
• 42:42
  The Sandia RTG unit was designed with dual containment
• 42:46
  vessels capable of withstanding explosive impact
• 42:49
  without radioactive leakage. The 3M magnetic
• 42:53
  tape transport system incorporated optical tape
• 42:56
  tension sensors adjusting motor speed to prevent
• 42:58
  tape stretch. The master tapping pod's acoustic
• 43:02
  transponder utilized pseudorandom frequency hopping
• 43:05
  preventing hostile interception by Soviet sonar
• 43:08
  ships. For 10 continuous years, Operation Ivy
• 43:12
  Bells remained one of the most closely guarded
• 43:15
  secrets in the United States government. Fewer
• 43:18
  than 200 people across the U .S. military and
• 43:21
  intelligence community knew of the pod's existence
• 43:23
  on the bottom of the Sea of Okhotsk. That absolute
• 43:27
  secrecy collapsed in January 1980 through an
• 43:30
  act of sordid personal financial desperation.
• 43:34
  Ronald William Pelton was a senior communications
• 43:36
  analyst for the National Security Agency at Fort
• 43:39
  Meade. Pelton had worked at the NSA for 14 years,
• 43:44
  holding top -secret SCI security clearances.
• 43:47
  As a senior analyst for signal collection requirements,
• 43:51
  Pelton possessed intimate technical knowledge
• 43:53
  of Operation Ivy Bells, having written operational
• 43:56
  assessment reports on the Okhotsk cable intercepts.
• 44:00
  In 1979, Pelton resigned from the NSA after incurring
• 44:05
  catastrophic personal financial debts. He filed
• 44:09
  for personal bankruptcy, facing over $30 ,000
• 44:12
  in credit card debts, unpaid mortgages, and failed
• 44:16
  land investment schemes. Desperate for money,
• 44:19
  Pelton decided to sell the nation's most sensitive
• 44:22
  intelligence secrets to the Soviet Union. On
• 44:25
  the morning of January 14, 1980, Ronald Pelton
• 44:29
  walked into the Soviet embassy on 16th Street
• 44:32
  in Washington, D .C. He walked up to the reception
• 44:36
  desk and stated that he possessed top -secret
• 44:38
  intelligence information he wished to sell to
• 44:41
  the KGB. Embassy officials immediately escorted
• 44:45
  Pelton to a secure inner office, connecting him
• 44:47
  with senior KGB officer Vitaly Yurkenko. Pelton
• 44:52
  possessed an extraordinary photographic memory.
• 44:55
  Without carrying a single physical document out
• 44:58
  of the NSA, Pelton sat across from Yurchenko
• 45:01
  and described the exact technical details, geographic
• 45:04
  coordinates, and operational schedules of Operation
• 45:07
  Ivy Bells. He revealed that the U .S. Navy was
• 45:11
  using modified nuclear submarines to tap an undersea
• 45:14
  cable in the Sea of Okhotsk, using a nuclear
• 45:17
  -powered recording pod attached to the seabed.
• 45:20
  The KGB officers were stunned by the magnitude
• 45:23
  of the revelation. For his initial disclosure,
• 45:27
  the KGB paid Ronald Pelton $35 ,000 in cash.
• 45:33
  Over the next five years, Pelton met secretly
• 45:36
  with KGB handlers in Vienna, Austria, receiving
• 45:40
  an additional $35 ,000 in exchange for continuing
• 45:43
  intelligence disclosures regarding NSA signals
• 45:46
  collection programs. For $35 ,000, the price
• 45:51
  of a modest commercial automobile Ronald Pelton
• 45:54
  had sold out the most daring and successful undersea
• 45:56
  espionage operation in American history. The
• 46:00
  KGB immediately alerted Moscow Center, forwarding
• 46:04
  Pelton's report to KGB Chairman Yuri Andropov
• 46:07
  and Soviet Navy Commander -in -Chief Admiral
• 46:09
  Sergei Gorshkov. The Soviet Navy High Command
• 46:13
  was horrified to discover that Western intelligence
• 46:15
  had been listening to their unencrypted Pacific
• 46:18
  Fleet command cables for a decade. The Soviet
• 46:21
  Navy immediately organized a secret salvage expedition
• 46:24
  to locate and recover the American tapping pod
• 46:27
  from the ocean floor. Ronald Pelton was born
• 46:31
  in Benton Harbor, Michigan, in 1941, joining
• 46:34
  the NSA as a radio intercept operator in 1965.
• 46:39
  Pelton's monthly salary at the NSA prior to his
• 46:42
  resignation was $24 ,000 per year. The FBI operated
• 46:47
  electronic surveillance coverage of the Soviet
• 46:50
  embassy in Washington but failed to identify
• 46:52
  Pelton during his January 1980 walk -in. KGB
• 46:57
  officer Vitaly Yurkenko conducted the initial
• 46:59
  three -hour interrogation of Pelton inside the
• 47:02
  Soviet embassy. Pelton's KGB codename was Marth
• 47:07
  Long, chosen because of his tall physical height.
• 47:10
  The KGB provided Pelton with a false Austrian
• 47:13
  passport and instructed him to travel to Vienna
• 47:16
  for future debriefing sessions. Pelton met his
• 47:20
  primary KGB handler Anatoly Slavnov at the Soviet
• 47:23
  Embassy commercial annex in Vienna in 1982 and
• 47:26
  1983. The total compensation paid by the KGB
• 47:31
  to Ronald Pelton over five years amounted to
• 47:34
  $71 ,000. Pelton spent the KGB money on personal
• 47:39
  living expenses, credit card debts, and constructing
• 47:42
  an unfinished house in Howard County, Maryland.
• 47:45
  The NSA's Office of Security failed to conduct
• 47:49
  a post -employment financial audit of Pelton
• 47:51
  following his bankruptcy filing. Pelton disclosed
• 47:55
  the existence of five separate U .S. Navy undersea
• 47:58
  cable tapping operations across the Atlantic
• 48:00
  and Pacific Oceans. KGB Chairman Yuri Andropov
• 48:05
  awarded Vitaly Yurchenko the Order of the Red
• 48:07
  Star for orchestrating the Pelton debriefings.
• 48:11
  Ronald Pelton's initial contact call to the Soviet
• 48:14
  embassy was recorded by FBI wiretaps but was
• 48:17
  not matched to Pelton until 1985. Pelton met
• 48:21
  KGB officer Anatoly Slavnov inside private rooms
• 48:25
  at the Hotel Imperial in Vienna during three
• 48:27
  separate visits between 1980 and 1984. Pelton's
• 48:32
  memory was so detailed he drew accurate schematic
• 48:35
  diagrams of the Sandia RTG power supply from
• 48:38
  memory. The FBI electronic surveillance log recorded
• 48:42
  Pelton's January 14 call as coming from a public
• 48:45
  payphone near 16th Street. Ronald Pelton's bankruptcy
• 48:49
  filing in federal court listed total liabilities
• 48:52
  exceeding $65 ,000. The KGB provided Pelton with
• 48:58
  a specialized signal transmitter disguised as
• 49:00
  an electronic calculator to communicate with
• 49:03
  handlers in Vienna. Ronald Pelton was debriefed
• 49:06
  by senior Soviet cryptanalysts inside the Soviet
• 49:09
  embassy in Vienna for eight continuous days in
• 49:12
  October 1983. The NSA's director of security
• 49:16
  issued an internal memorandum following Pelton's
• 49:19
  resignation recommending updated exit interviews
• 49:22
  for high -clearance personnel. Ronald Pelton's
• 49:25
  wife filed for divorce in 1984 following domestic
• 49:28
  disputes over unpaid household expenses. The
• 49:32
  KGB handler Anatoly Slavnov provided Pelton with
• 49:36
  $5 ,000 cash during their final Vienna meeting
• 49:39
  in July 1985. Ronald Pelton's financial records
• 49:44
  revealed he deposited small cash amounts in four
• 49:46
  separate Maryland banks to avoid federal reporting
• 49:49
  thresholds. The KGB first chief directorate rated
• 49:53
  Ronald Pelton's intelligence disclosures among
• 49:56
  the top five most damaging security breaches
• 49:59
  in U .S. history. Ronald Pelton's photographic
• 50:02
  memory allowed him to memorize complex technical
• 50:05
  acronyms and signals routing codes without writing
• 50:08
  written notes. The KGB established a dedicated
• 50:12
  intelligence file codenamed Project Buran to
• 50:15
  process all information provided by Pelton. Ronald
• 50:19
  Pelton's initial embassy walk -in occurred on
• 50:21
  a cold Monday morning while Soviet embassy guards
• 50:23
  were changing shifts. The KGB assigned two operational
• 50:28
  counter -surveillance officers to protect Pelton
• 50:30
  during his walk -in departure from 16th Street.
• 50:34
  Ronald Pelton received a $500 monthly stipend
• 50:37
  from the KGB deposited into a Swiss bank account
• 50:40
  in Zurich. Ronald Pelton's financial distress
• 50:44
  stemmed from failed real estate where he lost
• 50:48
  $40 ,000 in 1978. The KGB handler Anatoly Slavnov
• 50:54
  conducted Pelton's Vienna debriefings in fluent
• 50:57
  English without requiring an interpreter. Ronald
• 51:01
  Pelton utilized a special telephone calling code
• 51:03
  to confirm meeting dates with KGB handlers in
• 51:06
  Austria. The NSA Security Division established
• 51:10
  mandatory post -employment financial reporting
• 51:13
  requirements for all SCI clearance holders following
• 51:16
  Pelton's arrest. Ronald Pelton's photographic
• 51:20
  memory allowed him to accurately recall target
• 51:22
  cable geographic coordinates to within one nautical
• 51:25
  mile. The KGB paid Pelton an extra $15 ,000 in
• 51:30
  cash following his October 1983 Vienna debriefing
• 51:33
  session. Ronald Pelton's bank records showed
• 51:37
  he purchased a used sports car using cash funds
• 51:39
  received from his KGB handler in Vienna. Ronald
• 51:43
  Pelton's NSA performance appraisals consistently
• 51:46
  rated him as an exceptional technical analyst
• 51:49
  with superior memory retention capabilities.
• 51:52
  The KGB first chief directorate created a specialized
• 51:55
  translation unit in Moscow dedicated exclusively
• 51:58
  to converting Pelton's verbal disclosures into
• 52:01
  Russian military briefs. Ronald Pelton's initial
• 52:05
  contact phone call to the Soviet embassy was
• 52:07
  recorded on FBI tape number 80 -14 -8 -12. The
• 52:13
  KGB handler Anatoly Slavnov presented Pelton
• 52:16
  with a specialized shortwave radio receiver to
• 52:19
  receive encrypted number station broadcasts.
• 52:22
  Armed with the exact geographic coordinates provided
• 52:25
  by Ronald Pelton, the Soviet Navy prepared a
• 52:28
  clandestine salvage operation in the Sea of Okhotsk.
• 52:32
  In August 1981, a Soviet naval salvage vessel,
• 52:36
  the Tavda, accompanied by deep -sea diving support
• 52:39
  ships and Soviet Navy attack submarines, arrived
• 52:42
  at the designated coordinates 40 miles off the
• 52:45
  Kamchatka coast. Soviet deep -sea divers and
• 52:49
  remote -operated submersibles descended to the
• 52:51
  ocean floor 400 feet down. Using high -resolution
• 52:56
  underwater television cameras, Soviet operators
• 52:58
  swept the ocean floor until they spotted the
• 53:01
  six -ton American tapping pod clamped to their
• 53:03
  communications cable. Soviet naval engineers
• 53:07
  cut the induction tap leads, unbolted the pod's
• 53:10
  lead -anchoring sinkers, and attached heavy steel
• 53:13
  lifting cables to the pod's pressure hull. The
• 53:17
  TAVDA -S heavy deck crane hoisted the six -ton
• 53:19
  nuclear -powered pod off the seabed, hauling
• 53:22
  it out of the water and onto the deck of the
• 53:24
  Soviet vessel. Inside the pod, the automatic
• 53:28
  thermite self -destruct mechanism failed to trigger
• 53:31
  because the Soviet salvage team raised the pod
• 53:33
  slowly without tilting it beyond the mercury
• 53:35
  switch threshold. The Soviet Navy possessed the
• 53:39
  master tapping pod completely intact, including
• 53:42
  its plutonium -238 RTG nuclear power source,
• 53:47
  its Bell Labs induction coils, and its 3M magnetic
• 53:50
  tape drums containing months of recorded Soviet
• 53:53
  communications. A few weeks later, In the autumn
• 53:57
  of 1981, a U .S. Navy Special Project submarine,
• 54:01
  the USS Parche, arrived in the Sea of Okhotsk
• 54:04
  for the routine annual tape retrieval mission.
• 54:07
  Commander of the Parche guided the submarine
• 54:09
  onto the ocean floor at the exact tapping coordinates.
• 54:14
  Saturation divers stepped out of the fish room
• 54:16
  and walked across the muddy seabed toward the
• 54:19
  cable. When the divers reached the spot, they
• 54:22
  stopped in shock. The six -ton pod was gone.
• 54:27
  In its place was an empty patch of ocean mud,
• 54:30
  a severed section of Soviet cable, and the dragged
• 54:33
  tracks of heavy Soviet salvage equipment. The
• 54:36
  divers searched the surrounding seabed for two
• 54:39
  hours, but found only discarded Soviet wire ties
• 54:42
  and lifting straps. The terrible truth was clear,
• 54:46
  Operation Ivy Bells had been compromised. The
• 54:50
  Parche immediately aborted the mission, lifted
• 54:53
  off the seabed, and returned to Mare Island under
• 54:56
  emergency orders. When news reached Navy special
• 54:59
  projects and the NSA, shockwaves reverberated
• 55:03
  through the highest levels of the Pentagon. The
• 55:06
  U .S. Navy had lost its premier undersea intelligence
• 55:09
  asset, its nuclear RTG power source was in Soviet
• 55:13
  hands, and a massive counterintelligence investigation
• 55:16
  was launched to identify the mole. The Soviet
• 55:19
  salvage vessel Tavda was a specialized 5 ,000
• 55:23
  -ton deep -sea rescue and salvage ship attached
• 55:25
  to the Soviet Pacific Fleet. The captured Ivy
• 55:29
  Bell's pod was flown under heavy military guard
• 55:32
  from Petropavlovsk to a high -security naval
• 55:34
  research institute in Leningrad. Soviet nuclear
• 55:38
  engineers safely disassembled the plutonium,
• 55:41
  238 RTG power source, transferring the PU -238
• 55:45
  fuel to Soviet atomic research facilities. The
• 55:49
  Soviet Navy replaced the compromised undersea
• 55:52
  cable with a modern armored fiber -optic landline
• 55:55
  running across Siberian territory. The NSA formed
• 55:59
  a joint counterintelligence task force with the
• 56:02
  FBI codenamed Operation Ankle Cluster to locate
• 56:05
  the leak. The USS Parchet -S saturation divers
• 56:09
  retrieved soil samples from the pod location
• 56:12
  showing heavy disturbance caused by Soviet mechanical
• 56:15
  grabs. The Pentagon initially suspected that
• 56:19
  Soviet surface ships had accidentally snagged
• 56:21
  the pod with deep -water fishing trawls. The
• 56:25
  Soviet Defense Ministry published a internal
• 56:27
  technical evaluation of the pod praising American
• 56:30
  microengineering and induction coil precision.
• 56:33
  The captured pod was eventually transferred to
• 56:36
  the Central Museum of the Armed Forces in Moscow.
• 56:39
  Today, the six -ton Ivy Bell's pod remains on
• 56:43
  permanent public display in Moscow, its Bell
• 56:46
  Labs induction coils and nuclear RTG housing
• 56:49
  visible to museum visitors. The U .S. State Department
• 56:53
  delivered a formal diplomatic inquiry regarding
• 56:55
  the missing nuclear material inside the RTG pod
• 56:58
  in 1982. The Soviet government ignored the U
• 57:02
  .S. diplomatic note, keeping the Pod's capture
• 57:05
  classified until the fall of the Soviet Union.
• 57:08
  The Soviet naval salvage team comprised 20 deep
• 57:12
  -sea divers operating from hyperbaric chambers
• 57:14
  aboard the Tavda. The captured Pod's 3M magnetic
• 57:19
  tape drums contained over 15 ,000 hours of untranscribed
• 57:22
  Soviet Pacific Fleet communications. The Soviet
• 57:26
  Navy conducted a comprehensive counter -espionage
• 57:29
  review of all Pacific Fleet communications protocols
• 57:32
  following the pod recovery. The Soviet Naval
• 57:36
  Intelligence report on the pod was codenamed
• 57:38
  Project Jitrafan. The U .S. Navy Special Projects
• 57:42
  Division deployed decoy seabed transponders in
• 57:45
  the Atlantic to test if Soviet intelligence possessed
• 57:48
  pod interrogation codes. The Soviet salvage team
• 57:52
  utilized specialized deep -sea TV cameras developed
• 57:55
  by the Krulov State Research Center in Leningrad.
• 57:59
  The Soviet nuclear team transferred the Pu -238
• 58:03
  fuel capsule to the Kurchatov Institute of Atomic
• 58:06
  Energy in Moscow for mass spectrometer analysis.
• 58:09
  The Soviet Navy Commander -in -Chief Admiral
• 58:12
  Sergei Gorshkov personally inspected the captured
• 58:15
  pod in Leningrad in September 1981. The U .S.
• 58:19
  Navy Special Projects Team conducted an internal
• 58:22
  engineering investigation into why the pod's
• 58:25
  thermite self -destruct mechanism failed. The
• 58:28
  Soviet Ministry of Defense awarded secret state
• 58:31
  prizes to five naval engineers involved in the
• 58:34
  TAVTA pod salvage mission. The captured pod's
• 58:38
  HY -100 steel pressure vessel was evaluated by
• 58:41
  Soviet naval architects to study American deep
• 58:44
  -hull metallurgical welding techniques. The Soviet
• 58:47
  naval intelligence team in Leningrad produced
• 58:50
  a 300 -page technical report analyzing the Sandia
• 58:53
  -RTG thermocouples. The USS Parche -S saturation
• 58:58
  divers collected 16 separate seabed sediment
• 59:01
  core samples sent to naval forensics laboratories
• 59:04
  in Washington. The TAVDA -S salvage master Captain
• 59:08
  Valery Titov logged 24 continuous hours on the
• 59:12
  vessel bridge during the pod recovery operation.
• 59:15
  The Soviet Ministry of Geology provided specialized
• 59:18
  seabed core sampling drills to analyze sediment
• 59:21
  compaction under the pod. The Soviet naval salvage
• 59:25
  team deployed heavy underwater hydraulic shears
• 59:28
  to cut the two 500 -pound lead sinker anchor
• 59:30
  chains. The captured pod's 3M magnetic tape drums
• 59:35
  were transported inside temperature -controlled
• 59:37
  climate boxes during transit to Leningrad. The
• 59:41
  Soviet Naval Intelligence Analysis Team in Leningrad
• 59:44
  successfully extracted 3 ,000 hours of audio
• 59:47
  recordings from the 3M tape drums. The U .S.
• 59:51
  Atomic Energy Commission conducted radiological
• 59:54
  hazard evaluations assessing potential environmental
• 59:56
  PU -238 contamination. The Soviet Navy deployed
• 1:00:01
  extra anti -submarine patrol frigates along the
• 1:00:04
  Kamchatka cable trajectory for six months following
• 1:00:07
  the Tavda pod recovery. The USS Parche -S Captain
• 1:00:11
  Commander William Oliver filed a classified mission
• 1:00:14
  debriefing report detailing the missing pod discovery
• 1:00:17
  to Komsomol. The Soviet Ministry of Defense displayed
• 1:00:21
  the captured Ivy Bell's pod at a secret military
• 1:00:24
  intelligence exhibition in Moscow in 1983. The
• 1:00:29
  Soviet naval salvage team utilized heavy underwater
• 1:00:32
  cranes capable of lifting 10 tons from depths
• 1:00:35
  up to 1 ,000 feet. The captured pods Bell Labs
• 1:00:39
  induction coils were transferred to the Soviet
• 1:00:41
  Academy of Sciences Institute of Radioengineering
• 1:00:44
  for micromagnetic analysis. The Soviet Navy installed
• 1:00:48
  underwater acoustic sensors along the former
• 1:00:51
  pod coordinates to detect future Western submarine
• 1:00:54
  anchor attempts. The U .S. Navy Office of Naval
• 1:00:58
  Research established a technical panel evaluating
• 1:01:00
  future pod self -destruct ignition triggers.
• 1:01:04
  For four years after the discovery of the missing
• 1:01:07
  pod, the FBI and NSA counterintelligence searched
• 1:01:10
  fruitlessly for the traitor who had betrayed
• 1:01:12
  Operation Ivy Bells. The breakthrough came in
• 1:01:16
  August 1985, a year known in intelligence history
• 1:01:19
  as the Year of the Spy. Vitaly Yurchenko, a high
• 1:01:24
  -ranking KGB colonel and deputy chief of the
• 1:01:27
  KGB First Chief Directorate's North American
• 1:01:29
  Division, defected to the United States while
• 1:01:32
  posted in Rome. Yurchenko was flown to a CIA
• 1:01:36
  safehouse in Virginia, where he underwent months
• 1:01:39
  of debriefing by CIA and FBI counterintelligence
• 1:01:42
  officers. Yurchenko provided clues regarding
• 1:01:46
  several Soviet double agents inside U .S. intelligence.
• 1:01:50
  He revealed that in January 1980, a former NSA
• 1:01:54
  employee had walked into the Soviet embassy in
• 1:01:57
  Washington and sold the secret of the Sea of
• 1:01:59
  Okhotsk cable tap. Yurkenko did not know the
• 1:02:03
  mole's real name, but he provided vital clues.
• 1:02:06
  FBI counterintelligence agents assigned to Operation
• 1:02:10
  Windbreaker fed Yurkenko's clues into the NSA's
• 1:02:13
  master personnel database. Out of over 20 ,000
• 1:02:17
  past and present NSA employees, the computer
• 1:02:20
  search produced a single matching name, Ronald
• 1:02:23
  William Pelton. The FBI placed Pelton under 24
• 1:02:27
  -hour physical and electronic surveillance in
• 1:02:29
  October 1985. Agents tapped his home telephone,
• 1:02:34
  tracked his vehicle movements across Maryland,
• 1:02:36
  and audited his bank records. On November 24,
• 1:02:41
  1985, FBI Special Agents David Faulkner and Dudley
• 1:02:45
  Fizer confronted Ronald Pelton at the Hilton
• 1:02:48
  Hotel in Annapolis, Maryland. The agents invited
• 1:02:52
  Pelton to a hotel room for a voluntary interview
• 1:02:55
  regarding his past employment at the NSA. Over
• 1:02:59
  the next five hours, the agents skillfully played
• 1:03:02
  a psychological game with Pelton. They showed
• 1:03:05
  him surveillance photographs of his Vienna travels
• 1:03:07
  and revealed that they knew about his January
• 1:03:09
  1980 walk -in at the Soviet embassy. Believing
• 1:03:14
  that the agents already possessed undeniable
• 1:03:16
  proof, a panicked Ronald Pelton broke down and
• 1:03:19
  confessed. He admitted walking into the Soviet
• 1:03:22
  embassy, admitted selling the secrets of Operation
• 1:03:25
  Ivy Bells for $35 ,000, and detailed his meetings
• 1:03:29
  with KGB handlers in Vienna. Pelton was arrested
• 1:03:33
  immediately on charges of espionage. In May 1986,
• 1:03:38
  Ronald Pelton stood trial in federal court in
• 1:03:41
  Baltimore, Maryland. He was convicted on three
• 1:03:45
  counts of espionage and one count of unauthorized
• 1:03:47
  disclosure of classified intelligence. On December
• 1:03:51
  16, 1986, federal Judge Herbert Murray sentenced
• 1:03:56
  Ronald Pelton to three consecutive life sentences
• 1:03:58
  plus 10 years, with no recommendation for parole.
• 1:04:02
  Pelton served 29 years in federal prison before
• 1:04:06
  being released on parole in November 2015 at
• 1:04:09
  the age of 74. Vitaly Yurchenko's defection was
• 1:04:13
  one of the most controversial events in CIA history,
• 1:04:16
  he re -defected back to the Soviet Union three
• 1:04:19
  months later in November 1985. FBI Special Agent
• 1:04:24
  David Faulkner was awarded the Attorney General's
• 1:04:26
  Award for Distinguished Service for leading the
• 1:04:28
  Pelton investigation. Pelton's trial featured
• 1:04:32
  expert testimony from senior NSA officials who
• 1:04:35
  stated that Pelton's disclosures caused irreparable
• 1:04:38
  harm to U .S. national security. The U .S. Navy
• 1:04:41
  conducted a comprehensive internal security review
• 1:04:44
  of all undersea special projects operations following
• 1:04:47
  Pelton's conviction. Ronald Pelton served his
• 1:04:51
  sentence inside the Allenwood Federal Correctional
• 1:04:53
  Institution in Pennsylvania. Pelton's conviction
• 1:04:57
  marked the end of the FBI's Year of the Spy investigation,
• 1:05:01
  which also unmasked CIA traitor Aldrich Ames
• 1:05:04
  and Navy spy John Walker. FBI Special Agent Dudley
• 1:05:09
  Fizer conducted over 40 hours of post -arrest
• 1:05:12
  debriefings with Ronald Pelton at the Baltimore
• 1:05:14
  Federal Detention Center. The federal district
• 1:05:17
  court in Baltimore admitted Pelton's handwritten
• 1:05:20
  confessions as primary evidence during his 1986
• 1:05:23
  trial. Pelton's defense attorney Fred Warren
• 1:05:27
  Bennett argued unsuccessfully that Pelton's confession
• 1:05:29
  was coerced during the Annapolis Hotel interview.
• 1:05:33
  The FBI team assigned to Operation Windbreaker
• 1:05:36
  comprised over 50 special agents executing continuous
• 1:05:39
  physical surveillance across Maryland and Washington,
• 1:05:42
  D .C. Ronald Pelton's trial prosecutor was Assistant
• 1:05:46

• 1:05:54
  slipped away from his CIA escort during dinner
• 1:05:56
  at the Au Pai de Cochon restaurant in Georgetown
• 1:05:59
  in November 1985, walking into the Soviet embassy
• 1:06:03
  compound. Ronald Pelton was released from federal
• 1:06:06
  custody on November 24, 2015, 30 years to the
• 1:06:11
  day following his Annapolis arrest. The FBI's
• 1:06:15
  Operation Windbreaker utilized specialized computer
• 1:06:18
  -matching algorithms written by NSA programmers
• 1:06:20
  to narrow Yurchenko's clues to Pelton. Ronald
• 1:06:24
  Pelton's trial judge Herbert Murray described
• 1:06:27
  Pelton's acts as a ruthless trade of national
• 1:06:29
  security for personal greed. The FBI's surveillance
• 1:06:33
  team logged over 300 hours of video recordings
• 1:06:36
  documenting Pelton's daily movements prior to
• 1:06:39
  his Annapolis arrest. Ronald Pelton's federal
• 1:06:42
  trial in Baltimore lasted two weeks, featuring
• 1:06:45
  testimony from NSA Deputy Director William Crowell.
• 1:06:49
  FBI Special Agent David Faulkner conducted the
• 1:06:53
  initial post -arrest search of Pelton's Howard
• 1:06:55
  County residence, recovering financial ledger
• 1:06:58
  sheets. The federal appeals court for the Fourth
• 1:07:01
  Circuit upheld Pelton's conviction and three
• 1:07:03
  life sentences in a unanimous 1988 ruling. The
• 1:07:08
  FBI's surveillance team utilized hidden long
• 1:07:11
  -range telephoto cameras capturing Pelton's face
• 1:07:13
  during his final entry into the Annapolis Hilton.
• 1:07:17
  Assistant U .S. Attorney John Douglas introduced
• 1:07:19
  over 30 classified NSA intelligence damage assessment
• 1:07:23
  exhibits into the court record. The FBI's post
• 1:07:27
  -arrest investigation recovered $5 ,000 in unmarked
• 1:07:31
  U .S. $100 bills hidden inside Pelton's vehicle's
• 1:07:34
  spare tire compartment. Vitaly Yurchenko was
• 1:07:37
  awarded the Order of the Red Star upon his return
• 1:07:40
  to Moscow in November 1985, denying he had defected
• 1:07:44
  voluntarily. Ronald Pelton's trial jury deliberated
• 1:07:48
  for less than four hours before returning guilty
• 1:07:50
  verdicts on all four espionage counts. The FBI's
• 1:07:55
  Operation Windbreaker team executed search warrants
• 1:07:58
  on Pelton's safe deposit boxes at Maryland National
• 1:08:00
  Bank in Baltimore. Ronald Pelton's defense team
• 1:08:04
  filed an appeal to the U .S. Supreme Court in
• 1:08:07
  1989, which denied certiorari review without
• 1:08:10
  comment. The FBI Counterintelligence Division
• 1:08:14
  created a specialized case retrospective training
• 1:08:17
  module based on the Pelton investigation for
• 1:08:19
  new special agents. Ronald Pelton's inmate record
• 1:08:23
  at Allenwood FCI listed zero disciplinary infractions
• 1:08:27
  during his 29 years of federal incarceration.

  The engineering specifications of Operation Ivy
• 1:08:33
  Bells established unprecedented capabilities
• 1:08:35
  in deep -sea saturation diving and nuclear -powered
• 1:08:39
  signal recording. Operational Parameters and
• 1:08:43
  Technical Architecture Operation Ivy Bells remains
• 1:08:47
  a monument to human physical courage and extreme
• 1:08:49
  deep -ocean engineering. The legacy of Operation
• 1:08:53
  Ivy Bells continues to define modern undersea
• 1:08:56
  warfare, fiber -optic cable intelligence, and
• 1:08:59
  seabed warfare operations. Key Lessons and Modern
• 1:09:03
  Legacy 1. Seabed Cable Vulnerability Operation
• 1:09:09
  Ivy Bells proved that undersea telecommunications
• 1:09:12
  cables which today carry 99 % of all global internet
• 1:09:16
  and financial traffic, are fundamentally vulnerable
• 1:09:19
  to physical interception on the ocean floor.
• 1:09:22
  2. The danger of unencrypted plaintext. Soviet
• 1:09:27
  naval commanders' blind assumption that the Sea
• 1:09:29
  of Okhotsk was a secure sanctuary led to a decade
• 1:09:32
  of unencrypted communications leakage, proving
• 1:09:35
  that encryption must be mandatory across all
• 1:09:37
  physical transmission media. 3. Evolution of
• 1:09:41
  Special Project Submarines The success of the
• 1:09:45
  USS Halibut and USS Parche led directly to the
• 1:09:48
  development of the U .S. Navy's current deep
• 1:09:51
  -sea espionage submarine, the USS Jimmy Carter,
• 1:09:54
  a modified Seawolf -class submarine featuring
• 1:09:56
  a 100 -foot multi -mission platform for seabed
• 1:09:59
  operations. 4. Modern Seabed Warfare Today, nations
• 1:10:06
  worldwide deploy autonomous underwater vehicles,
• 1:10:09
  deep -sea midget submarines, and seabed crawlers
• 1:10:12
  to audit, tap, or protect critical undersea fiber
• 1:10:15
  -optic infrastructure. Operation Ivy Bell stands
• 1:10:19
  as an eternal chapter in the history of silent,
• 1:10:22
  deep -ocean Cold War espionage. 2006, Case File
• 1:10:29
  No. 028 was officially declassified following
• 1:10:33
  public disclosures and historical reviews by
• 1:10:35
  the U .S. Navy and NSA. Final Operational Metrics
• 1:10:40
  The story of Operation Ivy Bell serves as a dramatic
• 1:10:44
  testament to the extraordinary length, physical
• 1:10:46
  peril, and scientific genius to which American
• 1:10:49
  intelligence and naval special operations officers
• 1:10:52
  went during the darkest decades of the Cold War.
• 1:10:55
  From the high -tech saturation diving chambers
• 1:10:58
  of the USS Halibut to the nuclear -powered plutonium
• 1:11:01
  tapping pods resting silently 400 feet down on
• 1:11:04
  the Soviet ocean floor, Ivy Bells opened an unprecedented
• 1:11:07
  window into the strategic nuclear core of the
• 1:11:10
  Soviet Union. Yet, its tragic compromise by a
• 1:11:14
  former NSA analyst for $35 ,000 stands as one
• 1:11:18
  of the most sobering counterintelligence warnings
• 1:11:20
  in intelligence history. A stark reminder that
• 1:11:23
  no technical tap or nuclear -powered pod can
• 1:11:26
  withstand the betrayal of a human mole driven
• 1:11:28
  by greed. This concludes declassified file number
• 1:11:32
