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.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 332993 work as a small business.

1,500 employees
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.

Nose Plug and Support Cup
Solicitation # W519TC-25-R-NPSC
The Army Contracting Command - Rock Island is conducting market research to identify capable sources for the production and delivery of Nose Plugs and Support Cups used in MK80 General Purpose bombs. The government anticipates an annual requirement of 20,000 to 30,000 units for each item. Manufacturing these components requires specific expertise in forging, heat-treating, machining, cleaning, and coating. Interested vendors must demonstrate their technical capabilities, production capacity, and provide rough order of magnitude pricing for fiscal years 2027 through 2031. Future solicitations resulting from this research will be managed through the Procurement Integrated Enterprise Environment (PIEE) Solicitation Module, and offerors are encouraged to register early to avoid delays. Because the Technical Data Packages are classified as Distribution D, vendors must be registered with the U.S./Canada Joint Certification Program and have a SAM.gov account to access the drawings.

155mm Modular Artillery for Combat Effectiveness (MACE)
Solicitation # W15QKN26R1C5R
The 155mm Modular Artillery for Combat Effectiveness (MACE) program is a solicitation issued by the U.S. Army Contracting Command Rock Island at Picatinny to develop a manufacturable cargo-carrying artillery projectile system. This effort is being conducted via a Prototype Other Transaction Agreement (OTA) under 10 U.S.C. 4022, with the government intending to award up to two agreements. The project is divided into two phases: Phase I focuses on projectiles with a range of 30 to 35 km, while Phase II targets ranges beyond 35 km. The ultimate goal is to support a Milestone C production decision by the fourth quarter of FY29, with potential follow-on production of up to 10,000 systems per year. The procurement process has been refined through several amendments, most notably Amendment 0005, which corrected schedule discrepancies by aligning milestones to relative durations after award and updating the Statement of Work and CLIN Matrix. Proposals are due by October 30, 2026, and must be submitted via SAM.gov in four distinct volumes. Evaluation is based on schedule and technical merit, with schedule being the primary factor for Phase I and technical capability being the primary factor for Phase II, alongside cost and price. Technical requirements specify compatibility with M777A2 and M109A7 39-caliber weapon platforms, as well as legacy propellant systems. Deliverables include various quantities of engineering, safety, and soldier testing projectiles, as well as critical design reviews and technical reports. Due to the sensitive nature of the technology, offerors must comply with strict non-disclosure agreements and provide specific certifications, including Business Status Certifications and DD2345 Military Critical Technical Data Agreements, to access controlled technical data. All materials must adhere to the Buy America Act and International Standards for Phytosanitary Measures for wood packaging.
