FY2025 federal contract obligations, USAspending.gov
NAICS 332993 obligated $9.1 billion in FY2025 across 931 contract actions. DoD is $9.03 billion. State follows at $25 million, which is foreign military sales, and DHS at $3 million. There is no civilian market for this code in any practical sense.
What belongs here
Ammunition other than small arms: bombs, depth charges, unguided rockets, grenades, mines, and torpedoes. Two boundaries matter:
- Guided missiles are 336414, not this code, and the guidance package is what moves it.
- Small arms ammunition is 332992, and small arms plus ordnance accessories are 332994.
Energetics, load-assemble-pack operations, and warhead sections all sit inside 332993 when sold as ammunition items.
Competing in this code
447 IDVs against 931 total actions is the highest ratio of vehicles to awards anywhere in defense manufacturing, and it explains the structure of the market. Ammunition is bought on multi-year requirements contracts tied to the organic industrial base, with production allocated across government-owned plants and their operating contractors. New entrants do not compete for a bomb body award. They qualify as a second source on a specific component, or they win energetics and subassembly work behind an operating contractor. Safety siting, explosives licensing, and DoD Contractor's Safety Manual compliance are the gating investments, and they precede any award by years.
Frequently Asked
NAICS 332993 questions, answered.
What is the SBA size standard for NAICS 332993?
SBA sets it at 1,500 employees, counted as a 24-month average headcount across your company and every affiliate, not revenue. At or under that number you are small on NAICS 332993 solicitations and eligible for the set-asides in this code.
Which agencies buy ammunition under NAICS 332993?
FY2025 obligations: DoD ($9 billion), State ($25 million), DHS ($3 million). State's share is foreign military sales, which is the only lane in this code that reaches outside the DoD organic industrial base.
Are guided missiles included in NAICS 332993?
No. The code covers rockets except guided missiles, along with bombs, mines, grenades, depth charges, and torpedoes. Once a guidance package makes the round a guided missile, it classifies under 336414 for complete vehicles or 336419 for parts. That single distinction moves the buy between two entirely different program communities.
Why do IDVs matter so much in NAICS 332993?
Because 447 of the code's 931 FY2025 actions ran against indefinite delivery vehicles. Ammunition is procured on multi-year requirements contracts tied to the organic industrial base, so the qualifying competition is getting onto the vehicle or onto an operating contractor's approved source list, not winning an individual delivery order.
