USS Boise (SSN-764), a Los Angeles-class submarine, was the second ship of the United States Navy to be named for Boise, Idaho. The contract to build her was awarded to Newport News Shipbuilding and Dry Dock Company in Newport News, Virginia on 6 February 1987 and her keel was laid down on 25 August 1988. She was launched on 23 March 1991, and commissioned on 7 November 1992.

During a Joint Task Force Exercise (JTFEX) carried out in 1999, Boise was reported "sunk" by Dutch diesel-electric powered submarine HNLMS Walrus. In the same exercise Walrus reportedly also took down eight other allied vessels, including the aircraft carrier USS Theodore Roosevelt and USS Mount Whitney, flagship of the United States Sixth Fleet.


In 2002 Boise was assigned to the John F. Kennedy carrier strike group when the group took part in Operation Enduring Freedom.


In March 2003, Boise delivered some of the opening shots of Operation Iraqi Freedom when she launched a full load of Tomahawk missiles in support of the initial invasion. The ship and crew were later awarded the Navy Unit Commendation for their distinguished service in action.


As of February 2017, Boise is not dive certified as it awaits scheduled maintenance at Norfolk. Due to congestion and delays in Navy shipyards, it was planned that Boise would receive maintenance at a private shipyard during Fiscal Year 2019. However, due to unforeseen setbacks and delays, it is not expected to be repaired within the 2019 fiscal year.[1]


After a four year wait Boise has been moved into dry dock at Newport News. The wait has been attributed to a ten year lapse in capabilities and logistic setbacks discovered during the retrofit and restoration work done on submarines Helena and Columbus.[2] During the wait US Naval inspectors were able to thoroughly review the work being ordered, which will allow for a more cohesive process going forward.
