Enhanced multipurpose traced self-destruct 20mm projectile

Improved penetration and detonation delay with tracer and self-destruct features for land-based weapon systems

Military Technology

Army researchers at the Picatinny Arsenal have designed a medium-caliber munition with enhanced terminal effects for use in Counter-Rocket, Artillery, Mortar (C-RAM) missions. The patented technology is available to companies that would make, use, or sell it in accordance with applicable U.S. laws.

The ammunition contains an optimized projectile with a hardened penetrator and an explosive self-destruct mechanism for a high-rate-of-fire round. The penetrator is followed by a pyrotechnically initiated high explosive warhead that substantially increases the effective range and terminal performance against C-RAM targets.

The hardened segment penetrator localizes the kinetic energy of the projectile to increase target penetration prior to the initiation of the high explosive warhead.

The hardened segmented penetrator is manufactured with heavy tungsten alloy, reactive material, and alloy steel.

In tests, the inclusion of the hardened segmented penetrator and the dynamic interaction of the closure plug provided dramatically increased performance on large rockets and mortars compared to legacy solutions including the M940 round used in ground-to-air and ground-to-ground applications.
