U.S. military ordnance contractors

U.S. military ordnance contractors describes the U.S.-based private companies and government-owned, contractor-operated plants that produced bombs, ammunition, projectiles, and related ordnance for the armed services.

1 weapons

U.S. military ordnance production has historically combined Army ordnance authorities, private industry, and government-owned, contractor-operated ammunition plants. The Army Center of Military History describes wartime procurement as a War Department and private-industry effort that manufactured huge quantities of munitions, while National Archives records preserve the contract administration and plant records behind that production system.

This manufacturer grouping covers cases where public sources identify broad U.S. ordnance production rather than one branded company. It is most useful for munitions whose design, procurement, or plant-level production sat inside the Army and Air Force ordnance system, including M117-family bombs and ammunition produced through contractor-operated plants.

Notable Systems

M117 750-pound unguided bomb

750-pound unguided general-purpose bomb

The M117 is a U.S.-origin 750-pound-class general-purpose bomb from the 1950s. Air Force reporting describes the M117 and B-52 as entering the inventory in the same period, and the weapon record carries this broad U.S. ordnance-manufacturer attribution.

M117D destructor configuration

750-pound unguided general-purpose bomb

The M117D was the destructor and mine configuration within the M117 bomb family. The Air Force article describes an M117-family configuration with a magnetic-influence fuze for mine function, while T.O. 1-1M-34 documents the M117D retarded-bomb and destructor details.

This manufacturer grouping describes a dispersed U.S. ordnance-production network rather than one legal entity. Headquarters and corporate-relationship fields are omitted because the cited records describe Army ordnance administration, private contractors, and contractor-operated plants instead of a single company.
