The Komsomolets sank in the Norwegian Sea in 1989 after a fire on board killed 42 sailors.

The Soviet era submarine is also deep down, at 1,680m (5,525ft) and there are some fish in the area, they added. (ROV) examined and shot Komsomolets on July 7, revealing severe damage. The front part has six torpedo tubes and the submarine can also launch Granit winged missiles.

The news came a little over a week after the fire crossed a Russian nuclear submarine in the Barents Sea, killing 1
4 naval officers.
The survivors managed to bring their mini-submarine back to the Arctic base. Reactor shutdown
The Norwegian Authority for Radiation and Nuclear Safety (DSA) says the K-278 pressurized water reactor in April 1989 was shut down quickly when the fire broke out in another compartment.
Twenty-seven sailors have survived – eventually taken from two Soviet ships.
The radiation intention, opened this week, came from a pipe near the reactor. It is 800Bq (bekeres) per liter, while the normal level in the Norwegian Sea is about 0.001Bq.
Some other water samples from the rubble do not show elevated levels.   42 sailors who died in the disaster were subjected to toxic fumes or frozen in the Arctic's Arctic waters after the K-278 appeared briefly. The commander managed to send a disaster report an hour after the fire broke out, but he and four others died as their capsule sank. The submarine was doomed when the fire spread, fueled by high-pressure air from a damaged pipe, the Russian agency RIA reported.

Russia has previously examined the wreckage of a ship with underwater equipment and has found a leakage of radiation from the same section.
Norwegian radiation specialists and marine researchers were accompanied by experts from the Russian Association for the Study and Production of Typhoons.
"We took samples of water from this particular channel because the Russians documented leaks here in the 1990s and more in 2007," said Hilde Ellis Heldal, expedition leader
Norway and Russia regularly monitor radiation in the area from the crash, sometimes on joint expeditions."
The Komsomolet launched in 1983 and is 117 meters long (385 feet) and can dive to a maximum depth of 1250 meters. Its maximum score the axis is 30 knots (56 km / h).
