336992: Military Armored Vehicle, Tank, and Tank Component Manufacturing

What this code covers

NAICS 336992 covers manufacturing complete military armored vehicles, combat tanks, specialized components for combat tanks, and self-propelled weapons. Unarmored trucks and trailers, engines and general automotive parts sit under other codes, so the code is narrower than it sounds.

For a small shop it means hull and turret components, armor kits and add-on armor panels, hatches, ballistic doors and covers, track and suspension hardware, weldments, brackets, mounts and gun system parts. Army Contracting Command at Detroit Arsenal buys vehicles and kits for the Army tank and automotive commands, Marine Corps Systems Command buys for the Marines, DLA Land and Maritime in Columbus buys spares by stock number, and the Army depots at Anniston and Red River buy repair material.

What federal buyers typically ask for

ISO 9001 is the common floor, and armor work adds its own rules. Plate is specified by military detail specification, such as MIL-DTL-12560 for rolled homogeneous armor and MIL-DTL-46100 for high-hardness armor, with mill certs and ballistic acceptance testing. Welding on armor follows the Army ground combat vehicle welding codes, and welder and procedure qualification records are part of the data package. First article inspection is standard for a new source, and ballistic first articles are the expensive kind.

The DFARS specialty metals clause applies to armor steel and alloy hardware. Vehicle drawings are ITAR controlled under the ground vehicle category, and contracts with controlled unclassified information carry CMMC. DLA critical application items require source approval before award.

Vehicle-level production and major upgrades go sole source or unrestricted to the vehicle manufacturers. Spares and kits built from government-owned technical data packages are often small business set-asides, and the depots buy repair material the same way. Structural subassemblies for production reach small fabricators as subcontracts.
