The story of when the USS Kitty Hawk collided with a Soviet submarine. The submarine that was damaged was believed to be the VICTOR I class K-314. Of historical note in March of 1984, during Team Spirit 84 while operating in company with USS Long Beach CGN-9, the USS KITTY HAWK (CV-63) collided with surfacing Soviet submarine in the Tsushima Strait. On 21 March 1984, K-314 collided with the aircraft carrier USS Kitty Hawk in the Sea of Japan. The initial collision rolled K-314 onto her back, sparing the sail, periscope and antennas. A second strike broke loose a blade of her propeller which remained lodged in Kitty Hawk's hull. The carrier Kitty Hawk was not significantly damaged but the Soviet submarine could not get underway to proceed home for repairs under her own power. The frigate USS Harold E. Holt stayed on scene for several days before the Soviets could send out a seagoing tug to bring her home. Holt offered assistance several times after daybreak but was refused by K-314's captain. Navy Divers later removed a propeller piece as a souvenir, and samples of the submarine's hull coating were examined for intelligence purposes, a small piece of the submarine’s propeller was embedded in CV-63’s hull recovered and made into a souvenir. That piece is now part of the Naval Historical Center collection.
