• Namesake: USS Haddock (SSN-621) was the third U.S. Navy ship named after the haddock, a North Atlantic fish, continuing a tradition of naming submarines after sea creatures. • Class and Type: Haddock was a Permit-class (originally Thresher-class) nuclear-powered fast attack submarine, reflecting advancements in Cold War submarine design. • Construction: Her keel was laid down on 24 April 1961 at Ingalls Shipbuilding in Pascagoula, Mississippi, and she was launched on 21 May 1966. • Commissioning: USS Haddock was officially commissioned into service on 22 December 1967, with Commander Stanley J. Anderson in command. • PACFLT Service: She spent her entire career assigned to the United States Pacific Fleet, operating primarily out of Pearl Harbor, Hawaii, and later San Diego, California. • Vietnam Era Activity: During the Vietnam War, Haddock conducted covert intelligence-gathering and surveillance patrols in the Western Pacific, supporting U.S. naval operations. • Refit and Upgrades: Haddock underwent a significant overhaul and refueling at Mare Island Naval Shipyard in the late 1970s, extending her service life and updating her systems. • Notable Missions: The submarine participated in numerous Cold War operations, including tracking Soviet submarines and conducting special operations—many details remain classified. • Decommissioning: USS Haddock was decommissioned on 7 April 1993 after 25 years of service, and she was stricken from the Naval Vessel Register that same day. • Recycling: Her scrapping was completed via the Nuclear-Powered Ship and Submarine Recycling Program at Puget Sound Naval Shipyard in 2000, marking the end of her story.
