The submarine incident off Kildin Island was a collision between the US Navy nuclear submarine USS Baton Rouge and the Russian Navy nuclear submarine B-276 Kostroma near the Russian naval base of Severomorsk on 11 February 1992. The incident occurred while the US unit was engaged in a covert mission, apparently aimed at intercepting Russian military communications. Although most sources claim that the American submarine was trailing her Russian counterpart, some authors believe that neither Kostroma nor Baton Rouge had been able to locate each other before the collision.
