The USS Casimir Pulaski (SSBN-633) was a James Madison-class ballistic missile submarine constructed for the United States Navy. Built by the Electric Boat Division of General Dynamics in Groton, Connecticut, her keel was laid down on January 12, 1963, and she was launched on February 1, 1964. The vessel was commissioned on August 14, 1964, and featured a length typical of her class with a sleek, submarine hull designed for stealth and missile deployment. Her initial operational capability included the ability to carry and launch Polaris ballistic missiles, evidenced by her first dive on June 28, 1964, and her subsequent missile test firings in late 1964. She was assigned to Submarine Squadron 16 and conducted her first deterrent patrol in April 1965, operating out of Rota, Spain. Over her career, Casimir Pulaski completed a total of 88 deterrent patrols, the most among her original "41 for Freedom" fleet. Notably, she underwent significant upgrades: in 1970, her S5W reactor was replaced with an S3G core, allowing her to carry UGM-73 Poseidon missiles, and in the early 1980s, she was refitted to carry the UGM-96 Trident I missiles after her overhaul at Newport News Shipyard. Her service was marked by testing and operational achievements, including the first successful Poseidon missile launch in 1971 and multiple Trident missile tests in the mid-1980s. She earned several awards, including the Battle Efficiency (Battle "E") and the Fleet Ballistic Submarine Superior Performance Trophy, reflecting her combat readiness and operational excellence. The vessel participated in numerous strategic deterrent patrols, exercises, and special operations, contributing significantly to the U.S. Navy’s nuclear deterrence during the Cold War. Decommissioned on March 7, 1994, and scrapped later that year, USS Casimir Pulaski remains a notable example of Cold War submarine design and strategic deterrence, embodying the technological advancements and operational commitments of her era.
