Indefinite Delivery Contract N0002425D4330

Delphinus Engineering, Inc., a minority-owned small business headquartered in Newtown Square, Pennsylvania, was awarded a multiple-award Indefinite Delivery Contract by the Naval Sea Systems Command (NAVSEA) for the "CNO Availabilities for Fast Attack Submarines" program on September 2, 2025, with a ceiling value of $1.91 billion and an ultimate completion date of September 1, 2033. The contract encompasses two distinct work categories: Lot 1 Critical Systems Engineering and Lot 2 Non-Critical Systems Engineering, supporting discrete production, non-discrete production, and other production work required for the Navy's four public shipyards to conduct repair, maintenance, and modernization of nuclear-powered attack submarines. The scope includes hull, mechanical, and electrical system upgrades, technical analyses, engineering support, and critical fleet readiness initiatives. The contract was awarded without set-aside restrictions through a multiple-award vehicle designed to accommodate rolling admissions for additional contractors, reflecting NAVSEA's interest in competitive sourcing while supporting small business participation. Delphinus Engineering's award follows a pre-solicitation notice posted in July 2024 that sought industry capability for fast attack submarine availability work, with performance anticipated across multiple naval shipyard locations.

Under this indefinite delivery vehicle, Delphinus Engineering is executing task orders that support Chief of Naval Operations submarine availabilities, including a $5,000 firm fixed-price delivery order for Critical Systems Engineering (Lot 1) with an October 15, 2025 completion date, performed at the contractor's Pennsylvania headquarters. The contract builds upon Delphinus Engineering's existing NAVSEA portfolio, which includes an $88.1 million submarine preservation and repair contract, a $496 million engineering and technical services vehicle for hull, mechanical, and electrical machinery systems, and a $1.67 billion Littoral Combat Ship maintenance contract. The five-year base period with three option years provides a sustained mechanism for NAVSEA to allocate submarine maintenance and modernization requirements, with work anticipated to span various nuclear-powered attack submarine classes and support the Navy's overall fleet readiness objectives.
