General Dynamics Electric Boat Awarded Contract Modification for Overhaul of USS Hartford

General Dynamics Electric Boat, a business unit of General Dynamics, announced today it was awarded a modification of the previously awarded U.S. Navy contract for the repair, maintenance and modernization of the submarine USS Hartford (SSN 768). The contract modification has a value of $697.9 million. Work will be performed at the company’s shipyard in Groton, Connecticut, and is expected to be completed by October 2026. USS Hartford (SSN-768), a Los Angeles-class submarine, is the second ship of the Navy to be named for Hartford, Connecticut. USS Hartford is a Los Angeles-class submarine built by General Dynamics Electric Boat and commissioned in 1994.

“This engineered overhaul of the USS Hartford will enhance its warfighting capability and extend the ship’s service life, returning a valuable asset to the U.S. Navy submarine fleet,” said Kevin Graney, president of General Dynamics Electric Boat.

The Los Angeles class of submarines are nuclear-powered fast attack submarines (SSN) in service with the United States Navy. Also known as the 688 class (pronounced “six-eighty-eight”) after the hull number of lead vessel USS Los Angeles (SSN-688), 62 were built from 1972 to 1996, the latter 23 to an improved 688i standard. As of 2020, 32 of the Los Angeles class remain in commission — more than any other class in the world — and they account for more than half of the U.S. Navy’s 53 fast attack submarines. These boats are quieter, with more advanced electronics, sensors, and noise-reduction technology.
