Indefinite Delivery Contract N0002425D4329

Colonna's Ship Yard, Incorporated, doing business as Steel America, was awarded a multiple-award Indefinite Delivery Contract by the Naval Sea Systems Command on September 2, 2025, with a ceiling value of $1.91 billion and an ultimate completion date of September 1, 2033. This contract, designated OPW - LOT 2 NON-CRITICAL SYSTEMS ENGINEERING, supports the Navy's submarine maintenance, repair, and modernization operations through the provision of non-critical systems engineering services. The contract was awarded without set-aside designation to this prime contractor, which maintains operational facilities in Norfolk, Virginia, and Piney Point, Maryland. Colonna's Ship Yard will deliver discrete production, non-discrete production, and other production work in support of Chief of Naval Operations availabilities on nuclear-powered fast attack submarines, focusing specifically on non-critical work categories as differentiated from the contract's Lot 1 critical systems tier.

The underlying procurement initiative originated from a pre-solicitation notice posted by Naval Sea Systems Command on July 18, 2024, seeking industry capability and interest in supporting the Navy's four public shipyards with submarine modernization and maintenance work. The contract structure establishes a five-year base period with three option years and includes rolling admissions provisions to allow periodic addition of contractors. While the pre-solicitation notice indicated particular interest in small business participation and teaming arrangements, the final award to Colonna's Ship Yard as a prime contractor reflects the company's demonstrated expertise in federal maritime infrastructure support, including its existing portfolio of significant Indefinite Delivery Vehicle contracts totaling hundreds of millions in value across multiple maritime agencies. The scope encompasses engineering support for non-critical submarine systems, complementing the critical systems work awarded under the companion Lot 1 contract.
