US Cartridge, 105mm HEAT-T-MP, M456A2




This is a fixed cartridge with a fin stabilized high explosive antitank with tracer (HEAT-T) projectile. The projectile incorporates a setback armed, point initiating base detonating (PIBD) fuze containing a piezoelectric (Lucky) crystal and an electric detonator. The M509 series fuzes are impact fired.

The significant difference between the M509A1 and M509A2 fuzes is that the M509A2 is out-of-line detonator safe.

The projectiles are painted black or olive drab. The M456A1E2, M456A2, and M622 markings are white.
