Marine and shipbuilding procurement is a major component of US Department of Defense spending, with the Navy's shipbuilding account exceeding $30 billion annually. Contracts posted on SAM.gov range from $50,000 for vessel repair tasks to $15 billion for aircraft carrier and submarine construction programs at major shipyards including Huntington Ingalls Industries, General Dynamics NASSCO, and Bath Iron Works. Naval shipbuilding procurement follows DFARS and requires compliance with naval vessel rules, NAVSEA technical publications, and military specifications. Firms must hold facility security clearances, maintain ITAR compliance, and often meet Cybersecurity Maturity Model Certification (CMMC) requirements. The Navy's supplier base extends far beyond prime shipyards, with thousands of component manufacturers, system integrators, and marine service firms supporting the industrial base. Beyond Navy shipbuilding, the Coast Guard, NOAA, Army Corps of Engineers, and Military Sealift Command procure vessel construction, maintenance, and marine services. SBIR/STTR programs fund marine technology innovation, and the SBA mentor-protege program helps small firms enter the naval industrial base. Companies with expertise in marine propulsion, combat systems, autonomous vessels, and submarine technology find the strongest demand.
