Experimental Ammunition

Experimental Army and Air Force Artillery Ammunition

Explore experimental and developmental artillery ammunition associated with U.S. Army and Air Force weapons research. This category covers prototype rounds, test projectiles, trial casings, ballistic-test components, engineering samples, and limited-production designs created to evaluate new materials, configurations, performance characteristics, or weapon systems. Experimental ammunition may differ from standardized service rounds in its dimensions, construction, markings, driving bands, projectile shape, or internal design. All applicable ordnance is inert, deactivated, or empty and intended for historical display, collecting, technical study, or museum reference.
