The contracting approach will include advance planning, engineering, design efforts, prefabrication and shipyard execution work, including growth work and new work, necessary to prepare for and accomplish the maintenance and modernization work as defined in the USS Hartford EOH availability work package. Work will be performed in Groton, Connecticut, and is expected to be complete by February 2022.

The USS Hartford (SSN-768) is a Los Angeles-class nuclear-powered submarine build by the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 30 June 1988, and her keel was laid down on 22 February 1992. She was launched on 4 December 1993 sponsored by Laura O'Keefe, wife of former Secretary of the Navy Sean O'Keefe, and commissioned on 10 December 1994, with Commander George Kasten in command.

The Los Angeles class boats are nuclear-powered fast attack submarines (SSN) in service with the United States Navy. The U.S. Navy has been procuring Virginia (SSN 774) class nuclear-powered attack submarines (SSNs) since FY1998. The one Virginia-class boat that the Navy is requesting for procurement in FY2021 would be the 33rd boat in the class. The Navy’s FY2020 budget submission had projected that the Navy would request two Virginia-class boats in FY2021.

A total of 62 Los Angeles-class submarines, commonly called 688s, were procured between FY1970 and FY1990 and entered service between 1976 and 1996. They are equipped with four 21-inch diameter torpedo tubes and can carry a total of 26 torpedoes or Tomahawk cruise missiles in their torpedo tubes and internal magazines. The final 31 boats in the class (SSN-719 and higher) were built with an additional 12 vertical launch system (VLS) tubes in their bows for carrying and launching another 12 Tomahawk cruise missiles. The final 23 boats in the class (SSN-751 and higher) incorporate further improvements and are referred to as Improved Los Angeles class boats or 688Is. As of the end of FY2019, 32 of the 62 boats in the class had been retired.
