On 11 February 1992, Kostroma - then still named K-276 Crab - while undergoing combat training in the Barents Sea, collided with USS Baton Rouge (some sources state it was K-239 Carp that collided with Baton Rouge). Baton Rouge was damaged (as was Crab) and was eventually deactivated in 1993.

K-276 damaged the cabin fencing and the fairing of the hydroacoustic complex (GAK). The renovation was completed by June of the same year and the submarine re-entered the 7th Submarine Division of the Northern Fleet. SSN-689 "Baton Rouge" was handed over for recycling two years later, having ceased to exist in 1997.

On the K-276 wheelhouse, the crew drew the number "1", bordered with a star, as Soviet submariners did during the Great Patriotic War, noting the number of their victories. Foreign sources believed that the Baton Rouge collided with the K-239, another submarine of the same design as the K-276. There is a version that the collision was initiated by the Kostroma crew deliberately in order to get rid of the pursuit of an American submarine.[2]

On 14 May 2014, it became known about the conclusion of a contract between the Ministry of Defense of the Russian Federation and the enterprise TsS "Zvyozdochka" for the modernization of the Sierra I in Severodvinsk. The modernization will allow the submarine to be in service for about 10 more years. The timing of the repair work is not yet known.

However, in March 2015, it became known that the repair of the boats of Sierra I class had been suspended.[3][4]

As of 2020, B-276 is in reserve in Vizdyaevo as part of 7º Submarine Division.[5]
