US Cartridge, 81mm HE, M374A3 (M374A2E1)




This cartridge is used against personnel and materiel, providing both blast and fragmentation effects.

The complete round consists of a projectile body, a point-detonating fuze, a fin assembly four propellant charge increments, an ignition cartridge, and a percussion primer. The steel alloy body is threaded internally at the nose to accept the fuze, and threaded externally at the base to accept the fin assembly. The projectile body is filled with Comp B high explosive. The paper and brass ignition cartridge assembly contains a Percussion Primer M35, a black powder pellet, and approximately 115 grains of propellant M9. Surrounding the fin assembly are four horseshoe-shaped propelling charge M205 increments. Each propelling charge M205 increment consists of a nitrocellulose container holding approximately 400 grains of propellant M10. A protective plastic propelling charge support surrounds the four propelling charge increments.
