The USS Springfield (SSN-761) is a Los Angeles-class nuclear-powered fast attack submarine in the United States Navy. As the fourth vessel to bear the name, she honors the cities of Springfield, Illinois, and Springfield, Massachusetts. Constructed by the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut, her keel was laid on January 29, 1990, following the contract awarded on March 21, 1986. She was launched on January 4, 1992, with Lynn Martin serving as her sponsor, and was officially commissioned on January 9, 1993. Springfield measures typical of Los Angeles-class submarines, designed for stealth, agility, and advanced underwater capabilities. Her homeport was initially Pearl Harbor, but she transferred to Naval Base Guam on March 21, 2022, where she is assigned to Submarine Squadron Fifteen. Her operational history includes numerous overseas deployments, earning her several Meritorious Unit Commendations and Battle "E" Efficiency awards. In mid-2004, Springfield underwent an extensive Depot Modernization Period (DMP) at Electric Boat, marking the first major overhaul in nearly 25 years. The overhaul involved upgrades to fire control systems, sonar processing, weapons launch systems, communications, inertial navigation, stealth features, and engine room systems. Originally scheduled as a 12-month, $26.3 million project, the overhaul faced delays and cost overruns, culminating in completion in December 2005. This significant upgrade aimed to modernize the vessel’s combat and stealth capabilities, although it resulted in Electric Boat not securing further DMP contracts afterward. Springfield has also undergone a planned engineering overhaul at Portsmouth Naval Shipyard starting December 2016, focusing on modernizing her engine room systems. Throughout her service, she has earned recognition for excellence in navigation, engineering, medical, supply, damage control, and deck seamanship. Notably, she received the Captain Edward F. Ney Silver Cup Trophy in 1998 for outstanding food service and the Retention Excellence Award in 2003, reflecting her operational and crew excellence. Springfield's history exemplifies the evolving technological and operational standards of modern submarine warfare.
