Three sailors were killed outright in the explosion. The vessel surfaced to permit its twin nuclear reactors to be shut down, which was only accomplished when a 19-year old enlisted seaman, Sergei Preminin, sacrificed his life to secure one of the onboard nuclear reactors by hand, trapped in the engine compartment. Captain Second Rank Igor Britanov was ordered to have the ship towed by a Soviet freighter back to Gadzhievo, her home port, some 7,000 kilometers (4350mi) away.
Although a towline was attached, towing attempts were unsuccessful, and after subsequent poison gas leaks into the final aft compartments and against orders, Britanov ordered the crew to evacuate onto the towing ship. Britanov remained aboard K-219.
Displeased with Britanov's inability to repair his submarine and continue his patrol, Moscow ordered Valery Pshenichny, K-219’s security officer, to assume command, transfer the surviving crew back to the submarine, and return to duty. Before those orders could be carried out, however, K-219 abruptly sank into the Hatteras Abyss on 6 October 1986
, in a depth of about 6,000 meters (18,000 ft). While the proximate cause of the sinking is unknown, some evidence indicates Britanov may have scuttled her. K-219's full complement of nuclear weapons was lost along with the vessel.
Preminin earned the Red Star, awarded posthumously, for his bravery in securing the reactors. Britanov was charged with negligence, sabotage, and treason. He was never imprisoned, but waited for his trial in Sverdlovsk. In May 1987, after a new Defense Minister took office in Moscow, the charges against Britanov were dismissed.
An article on the US Navy's website posted by Captain 1st Rank (Ret.) Igor Kurdin (former XO of K-219) and Lieutenant Commander Wayne Grasdock denied any collision between K-219 and the Augusta. Captain Britanov himself also denies a collision. He has stated that he was not asked to be a guest speaker at Russian functions because he refuses to follow the Russian government's interpretation of the K-219 incident.
