Laid down 9 September 1957. Launched 31 May 1959. Commissioned 31 December 1959.

On 12 April 1970, after four days on the surface, K-8 sank returning from patrol and participation in the large scale "Okean-70" naval exercise.<ref name="PLR1"/> The accident occurred due to short circuits that took place in III and VII compartments simultaneously at a depth of 120&nbsp;m and a subsequent fire in the air-conditioning system. This was the first loss of a Soviet nuclear-powered submarine. 52 sailors including the commander, Captain 2nd Rank [[Vsevolod Borisovich Bessonov]], died due to {{CO2}} poisoning and the flooding of the surfaced submarine during 80 hours of damage control in stormy conditions, 73 sailors were rescued. K-8 sank with four nuclear torpedoes on board at a depth of 4,680&nbsp;m (Bay of Biscay).{{Citation needed|date=August 2009}}. There were also three small incidents with K-8 whilst on patrol before (breakdowns of steam generators in 1960–1961).
