Indefinite Delivery Contract N0002425D4337

HII Mission Technologies Corp, a subsidiary of Huntington Ingalls Industries, Inc., was awarded a multiple-award Indefinite Delivery Contract by Naval Sea Systems Command (NAVSEA) on September 2, 2025, with a ceiling value of $762.4 million and ultimate completion date of September 1, 2033. This contract, designated as OPW - Lot 1 Critical Systems Engineering, will support Chief of Naval Operations availabilities on fast attack submarines through the provision of specialized engineering and technical services. The contract carries no set-aside designation, reflecting the contractor's capabilities to compete on an unrestricted basis. The award stems from NAVSEA's market research and pre-solicitation efforts, which sought industry capability for discrete production, non-discrete production, and other production work to support the Navy's four public shipyards in accomplishing repair, maintenance, and modernization of nuclear-powered attack submarines.

The Lot 1 designation indicates that HII Mission Technologies Corp will focus on critical systems engineering work requiring greater specialized capabilities, as opposed to non-critical efforts under a separate Lot 2 contract vehicle. The underlying solicitation contemplated a five-year base period with three option years and rolling admissions provisions to add additional contractors periodically. As a subsidiary of the nation's largest military shipbuilding company with extensive experience in naval platform support, systems engineering, and technical services delivery, HII Mission Technologies Corp is positioned to provide integrated engineering solutions supporting critical submarine maintenance and modernization missions across the Department of Defense's attack submarine industrial base.
