NAICS 332993: Ammunition (except Small Arms) Manufacturing

NAICS 332993 – Ammunition (except Small Arms) Manufacturing encompasses the production of explosive ordnance and propellant systems for military applications, including artillery shells, mortar rounds, guided missile warheads, demolition charges, and other medium- to large-caliber munitions. This sector supports critical defense readiness through the design, fabrication, testing, and certification of munitions that meet stringent military specifications such as MIL-STD and NATO STANAG standards. Manufacturing involves precision metallurgy, high-energy chemistry, and advanced assembly processes under strict safety and quality control protocols. In the federal contracting landscape, this NAICS code serves as a cornerstone of the Department of Defense’s sustainment and modernization efforts, linking industrial base capacity with operational needs across land, air, and naval platforms. Top contractors in this space include EPS CORPORATION, DELOITTE CONSULTING LLP, PROGRAMMED RESPONSE LLC, EG&R ENGINEERING PC, and MANTEL TECHNOLOGIES, INC., representing a mix of specialized defense manufacturers, engineering service providers, and systems integrators. Many are small to mid-sized firms with niche expertise in ordnance logistics, compliance, or technical support, while others offer broader defense consulting services that enable ammunition lifecycle management. The Department of Defense is the dominant buyer, driving demand through munitions replenishment, modernization of legacy stockpiles, and support for overseas contingency operations. Programs under Army Materiel Command, Naval Sea Systems Command, and Air Force Life Cycle Management Center are primary sources of procurement, with emphasis on reliability, interoperability, and extended shelf life. The competitive landscape is characterized by high regulatory barriers and technical specialization, creating opportunities for firms with certified manufacturing facilities, explosives handling expertise, and experience in defense supply chain compliance. Demand remains steady due to ongoing modernization initiatives and the need for domestic production resilience.
