Skipjack-class Submarines

Pacific Fleet fast-attack operations through the Cold War. Intelligence collection and barrier patrols in the Western Pacific. Speed advantage over Soviet submarines was classified for decades because the differential was that significant.

Lost with all 99 hands on 22 May 1968 southwest of the Azores. Cause officially undetermined. Located at 9,800 feet depth in October 1968. Loss drove fundamental changes in U.S. Navy submarine safety procedures. Her crew remains on eternal patrol.

Atlantic Fleet Cold War anti-submarine warfare and intelligence operations. Teardrop hull speed allowed prosecution of Soviet submarines that slower designs could not match. Served through the most contested decades of North Atlantic submarine competition.

Atlantic Fleet Cold War operations. Direct predecessor hull to the Permit and Sturgeon classes. Operational experience contributed to data that shaped subsequent designs. Decommissioned 1996 after 35 years of nuclear submarine service.

Pacific Fleet Cold War operations. Western Pacific barrier patrols and intelligence missions tracking Soviet submarine movements. Demonstrated the full operational scope of the Skipjack design: find, track, and prosecute Soviet submarines before they could threaten carrier battle groups.
