Nuclear Sub Missing - Here's what you need to remember: In the mid-1980s, the Soviet Union built a superyacht unlike any other. Submarine, fast and able to offer depth for a bottom battle
And its nuclear weapons were at the bottom of the ocean, killing two-thirds of its crew in what was seen as another example of Soviet incompetence.
Nuclear Sub Missing
Back in 1966. Rubin Design Bureau n. A. A team under Klimov and chief engineer Y. N. Kormilitsyn was assigned to begin research on Project 685, a deep-sea submarine. Research efforts continued for eight years, perhaps due to the lack of suitable steel that can withstand the great pressure of depth. In 1974, however, the two-part design was completed with a titanium alloy chosen for the interior.

Project 685, known as K-278, will be a prototype vessel to test deep-sea probes in the future. Construction began at the Sebamash Shipyard on April 22, 1978 and the ship was officially completed on May 30, 1983. Difficulties in refining the titanium resulted in long construction times.
The K-278 is 360 feet long and forty feet wide, with an interior about twenty-four feet wide. It weighs about 6,500 tons, and the use of titanium instead of steel made it lighter. It has a unique double hull design with a titanium inner core, which gives it the ability to dive deep. The interior was divided into seven sections, two of which were reinforced to form a safety zone for the crew, and an escape pod was built into the sun to allow the crew to escape. abandon ship as it sinks to depths of up to 1,500. meter
The ship was powered by a 190-megawatt OK-650B-3 nuclear reactor, which was powered by two forty-five thousand-ship-horsepower engines evening. It was thus launched at a speed of thirty knots and a top speed of fourteen knots.
Underneath was a MGK-500 "Skat" (NATO code name: Shark Gill) low-frequency passive/active search and attack spherical bow array sonar system, the same sonar used today these are Yasen-class attack submarines, fed by omnibus. -685 Information Management System. Weapons include six 533-millimeter torpedo tubes, including twenty-two Type 53 torpedoes and Shaqval supercavitating antisubmarine torpedoes.

The ship joined the Red Banner Northern Fleet in January 1984 and began a series of deep dive trials. The ship, under Captain First Rank Yuri Zelensky, recorded a depth of 3,346 feet - an impressive figure considering its American counterpart, the USS Los Angeles class, has a higher depth of 1,475 feet. The depth of the breach was estimated to be about 4,500 feet. The ship had a special ground system, the "Iridium", which used gas engines to blow up rubber tanks.
The Soviet Navy considered the K-278 to be invulnerable to depths greater than 1,000 meters; At this depth, it was difficult to detect enemy torpedoes, especially the American Mark 48, which had a maximum depth of eight hundred meters. Although the ship was originally intended as a demonstration ship, it finally became a fully operational ship in 1988. It was named
Norway had an accident in the middle of the sea. According to Norman Polmer and Kenneth Moore, the ship's second crew, they have just been trained to operate the ship. In addition, its origin as a prototype ship means that there are no parts to spoil.
A fire broke out in the seventh rear room and burned an air supply valve, which supplied heavy air to the fire. The fire extinguishing system has failed. The reactor went up and the tanks blew up on the ship. The fire continued to spread, and the crew battled the flames for six hours before the ship was ordered to abandon ship. According to Polmer and Moore, the fire was so intense that the crew of the deck saw the skin that covered the outer part of the body had slipped away due to the extreme heat.
The Terrifying History Of Russia's Nuclear Submarine Graveyard
The ship's commander, Captain First Rank Evgeny Vanin, along with four others, returned to the ship to find the crew who were not The order to abandon ship was heard. Vanin and his rescue team didn't get too far—the ship entered the rescue chamber in an eighty-degree headwind. The first room could not leave but was finally freed from the wound. Once aloft, a sudden change in pressure caused the top to open, ejecting the two crew members from the cabin. Chamber, as well as the captain and the rest of the rescue team, drowned under the waves.
Only four people have died in the accident so far, but many have lost their lives in the thirty-six degree (F) water when the ship sank. The fishing boat arrived one hour later
Arrived and rescued thirty people, some of whom later died of their wounds. Of the sixty-nine men on board at the time of the accident, 42 died, including Captain First Rank Vanin.
Komsomolets sank in 5,250 feet of water, along with its nuclear reactor and two nuclear-armed torpedoes. Between 1989 and 1998 seven actions were taken to protect the reactor from media and to seal the torpedo tubes. The Russian information states that during these inspections, evidence of "unauthorized investigation of sunken ships from abroad" was found.
