The USS Patrick Henry (SSBN-599) was a George Washington-class nuclear-powered fleet ballistic missile submarine constructed by the Electric Boat Division of General Dynamics in Groton, Connecticut. Her keel was laid on 26 May 1958, and she was launched on 22 September 1959, with Mrs. Betty Arends serving as the sponsor. Commissioned on 9 April 1960, the submarine featured dual crews, known as the Blue and Gold crews, to maximize submerged operational time. Her initial shakedown period was conducted with the Blue crew until 16 September 1960, after which the Gold crew took over. As the second fleet ballistic missile submarine, Patrick Henry embarked on her first deterrent patrol in December 1960. Notably, she set a record by cruising submerged for 66 days and 22 hours during a patrol, and she was the first ballistic missile submarine to enter Holy Loch, Scotland, and to dock alongside the submarine tender USS Proteus for routine replenishment. She conducted a total of 17 deterrent patrols from Holy Loch until December 1964, when she returned to Electric Boat for an extensive overhaul, including reactor refueling and modifications to handle Polaris A-3 missiles. By mid-1966, Patrick Henry was equipped with A-3 Polaris missiles and assigned to Submarine Squadron 14, conducting patrols from her home port, Charleston, South Carolina. Her operational history extended into the early 1970s, with her home port shifting to Pearl Harbor, Hawaii. In 1976, she underwent refueling at Mare Island Naval Shipyard. To ensure operational readiness, she participated in Demonstration and Shakedown Operations (DASO) in 1978, culminating in successful missile firings off Cape Kennedy. In 1982, Patrick Henry was reclassified as an attack submarine (SSN-599) after the disabling of her ballistic missile tubes. She was decommissioned and struck from the Naval Vessel Register on 25 May 1984. Her disposal was completed through the Ship-Submarine recycling program at Puget Sound Naval Shipyard by 1997. Patrick Henry's service exemplifies the Cold War-era naval strategy and technological advancements in nuclear submarine capabilities.
