General Dynamics NASSCO received a U.S. Navy contract to provide depot-level maintenance to the USS Boxer.

The deal, announced on Oct. 28, is for a sum not to exceed $83.0 million.

The USS Boxer is a Wasp-class amphibious assault ship. The 884-foot vessel has a large, flat main deck where aircraft can land vertically, in addition to a well deck for launching landing craft. In addition to a crew of 1,070 officers and sailors, the ship carries a detachment of 1,700 Marines.

The Boxer first deployed in 1997 and is based in San Diego. A break from service called a maintenance availability will include a program of maintenance, alterations and modifications. Work is expected to be complete by October 2017.
