K-159 was a Project 627A "Kit" (NATO reporting name November class) nuclear-powered submarine of the Soviet Northern Fleet.
On 28 August 2003, K-159 and her pontoons were manned by ten Russian sailors and taken under tow to Polyarny. That crew kept the pontoons pressurised and the submarine hull pumped out, but during the early morning hours of 30 August they encountered a squall that ripped away one of the pontoons. K-159 did not sink immediately, but was clearly in distress. Northern Fleet was notified at 0120, and Admiral Suchkov arrived at headquarters 20 minutes later. Suchkov made no attempt to rescue the submarine crew. By 0300 the wreck had sunk in the Barents Sea, 238 meters down, with nine of her crew and 800 kilograms of spent nuclear fuel containing some 20 petabecquerels (600 kilocuries) of radioactivity.
