Description
To provide antimateriel and antipersonnel capabilities in a submunition, with self-destruct feature. The grenades are delivered by 105mm M915 cartridge for howitzers.
The M80 grenade is a ground burst munition. The shaped charge contains approximately 16 grams of Comp PAX-2A and has a trumpet-shaped liner. The grenade body is embossed for fragmentation.
The inertia type fuze is similar to an M42 grenade fuze, with the addition of self-destruct action. The firing pin (combination arming screw) locks the slide assembly in the safe position. The ribbon parachute is attached to the arming screw, and is fluorescent pink in color.
The slide assembly contains the self-destruct system and an M55 detonator. Main self-destruct components are the reserve battery, integrated circuit, electro-explosive device, shunt, and battery safety spiral. The battery initiating mechanism is restrained by the battery safety spiral. Rotation or removal of the battery safety spiral will result in activating the battery. The battery provides electricity to the integrated circuit. Current flowing through the circuit for approximately three minutes will function the electro-explosive device. This will initiate the M55 detonator. The shunt is the electrical safety. In the event that the battery is activated during handling, the shunt provides a safe alternate path for current, and the battery power will be drained.
