The USS Boise (SSN-764) is a Los Angeles-class nuclear-powered attack submarine of the United States Navy. As the second vessel to bear the name, she honors the city of Boise, Idaho. Her construction was awarded to Newport News Shipbuilding and Dry Dock Company in Newport News, Virginia, with her keel laid down on August 25, 1988. The submarine was launched on March 23, 1991, and officially commissioned on November 7, 1992. Boise features the typical design of the Los Angeles class, which is known for its nuclear propulsion, enabling extended submerged operations and high speeds. She played an active role in various military operations and exercises throughout her service life. Notably, during a 1999 Joint Task Force Exercise, Boise was reportedly "sunk" by the Dutch diesel-electric submarine HNLMS Walrus, which also reportedly sank eight other allied vessels, including the aircraft carrier USS Theodore Roosevelt and the USS Mount Whitney. This exercise highlighted the capabilities and vulnerabilities of modern submarines. In 2002, Boise was assigned to the John F. Kennedy carrier strike group and participated in Operation Enduring Freedom. She also played a significant role in the initial stages of Operation Iraqi Freedom in March 2003, launching a full load of Tomahawk missiles to support the invasion. For her distinguished service, Boise and her crew received the Navy Unit Commendation. As of recent years, Boise has faced maintenance delays. By February 2017, she was no longer dive-certified and was awaiting scheduled maintenance at Norfolk. Due to congestion and delays at Navy shipyards, her maintenance was postponed, with plans to conduct work at a private yard in 2019, but this was delayed until early 2021. As of 2025, she remains in drydock, with repairs expected to conclude in 2029, following setbacks related to capabilities and logistics discovered during retrofit work on other submarines. Boise's ongoing maintenance underscores the challenges faced in modern submarine sustainment and modernization efforts.
