The USS Parche (SSN-683) was a Sturgeon-class nuclear-powered attack submarine of the United States Navy, notable for its extensive clandestine operational history and technological modifications. Launched on January 13, 1973, and commissioned on August 17, 1974, the vessel was named after the small, coral reef butterfly fish, the parche. She served initially with the Atlantic Fleet before transferring to the Pacific Fleet in October 1976, with her new home port at Mare Island Naval Shipyard in Vallejo, California. Constructed as a nuclear-powered fast attack submarine, Parche was later extensively modified during a major overhaul from 1987 to 1991 at Mare Island. This overhaul added a 100-foot extension to her hull, creating space for advanced signals intelligence (SIGINT) equipment, antennas, and electronic gear. The modifications also included enhanced sonar systems, armored spotlights, and closed-circuit television cameras optimized for under-ice operations, transforming her into a highly capable reconnaissance platform. Parche is reputed to have played a crucial role in covert operations, including tapping Soviet underwater communication cables, as detailed in the book "Blind Man’s Bluff." It is believed she successfully retrieved Soviet missile fragments and possibly Chinese missile debris during crises such as the Third Taiwan Strait Crisis, contributing to intelligence gathering efforts. Throughout her career, Parche earned a reputation as the most highly decorated U.S. submarine, with nine Presidential Unit Citations, ten Navy Unit Commendations, and numerous other medals. Her operational history remains largely classified, but she was attributed with significant signals intelligence and reconnaissance missions, making her a key asset of the National Underwater Reconnaissance Office. Decommissioned on July 18, 2005, and scrapped in 2006, Parche’s sail was preserved and displayed near the Puget Sound Navy Museum, symbolizing her distinguished service. Her technological and operational legacy underscores her importance in Cold War naval espionage.
