United States Marine Inc.

United States Marine Inc., a for-profit manufacturer headquartered in Gulfport, Mississippi, manufactures specialized naval watercraft and delivers training and logistics support to the Department of Defense as a prime contractor (93% of recent awards) and as a subcontractor to larger primes. The company does not hold SBA set-aside certifications and competes on full-and-open basis across all recent prime work.

United States Marine Inc. specializes in the design, production, modernization, repair, and maintenance of rigid inflatable boats (RIBs), Combatant Craft Assault (CCA) vessels, and specialized patrol craft, along with associated training, spare parts provisioning, and integrated logistics support. Core capability work includes the manufacture and delivery of 11-meter Navy Special Warfare RIBs under a $57.76 million single-award IDC with Naval Sea Systems Command (ultimate completion September 29, 2025), full-rate production of CCA vessels under a $22.78 million Air Force delivery order (January 21, 2026 completion), and a $7.3 million Naval Sea Systems Command delivery order for ready-for-issue preparation and modernization of twelve Naval Surface Warfare 11-meter RIB hulls (October 1, 2026 completion). The company also delivers CCA training services under a $6 million single-award IDIQ with U.S. Special Operations Command (June 8, 2030 completion) and holds a new $85.2 million single-award Indefinite Delivery Contract with USSOCOM for CCA vessel procurement and spare engines through August 28, 2030.

Customer concentration is extreme. The top two funding agencies account for 98% of combined potential value: U.S. Special Operations Command (709 awards, $1.3 billion) and Naval Sea Systems Command (271 awards, $722.1 million). The Air Force ranks third with 61 awards valued at $41.2 million. The Department of Homeland Security Coast Guard (9 awards, $12.5 million) and GSA (2 awards, $3.9 million) complete the active set. These five agencies represent 93% of the 1,154 total awards in the source data.

Activity peaked at 41 awards in 2023, with 36 awards in 2024 and 39 in 2025 (6 awards recorded in 2026 to date). Eight awards with combined potential value of $53.2 million reach ultimate completion within the next twenty-four months, creating recompete exposure in that window.
