Sinking
During the night of 26 January 1961, S-80 was operating in the Barents Sea at snorkel depth on its diesel engines. The ocean was at sea state 6 and air temperature was −5 °C (23 °F). At 01:27 on 27 January, the boat dropped below snorkel depth, which should have caused the automatic snorkel valve to shut, preventing water from entering the snorkel system. However, the de-icing system that should have warmed the valve with hot water from the diesel engines had been switched off, and the valve had become jammed with ice.
The diesel engines failed immediately as seawater flooded their air intakes. The machinist in the fifth compartment who discovered the flooding became confused by the complex array of valves, and did not shut the ventilation flapper valve quickly enough. By the time he located the correct handwheel, the valve spindle had been bent by the force of the flooding water. As the compartment filled, the boat's trim became uncontrollable.
As its up-angle passed 45 degrees, the boat slowed, coming to a halt and then falling backward, gathering sternway and sinking until it grounded. The second, third, and fourth compartments were crushed, though 24 crewmen survived in the after compartments. Their attempts to escape the wrecked submarine using IDA-51 apparatuses failed, and all 68 officers and men of S-80 were lost. Their fate remained unknown for seven and a half years.
Recovery
On 23 June 1968, salvage vessel Altay discovered the wreck of a submarine at 70°01′23″N 36°35′22″E, at a depth of 196 m (643 ft). The crew inspected the wreck with its
A government commission studied the report and ordered Operation "Depth," the salvage of the wreck. The
Operation "Depth" was carried out by a task force of the Northern Fleet consisting of groups of trawlers and a destroyer under the command of Captain First Rank S. Minchenko. The wreck was lifted from the ocean floor on 9 June 1969 and transported to Mys Teriberskiy, suspended under Karpaty in slings. There, it was lowered to the bottom of Zavalishin Harbor at a depth of 51 m (167 ft) on 12 July.
On 24 July 1969, S-80 was raised to the surface. During August, a government commission began studying the wreck under the management of Hero of the Soviet Union Vice Admiral Grigory Shchedrin. The commission determined not only the immediate causes of the boat's loss, but also that two further errors had compounded the accident: the crew never attempted to shift propulsion to the electric motors, and they never performed an emergency ballast tank blow.
