M67 Hand Grenade Heat Test
Abstract
The M67 hand grenade is a traditional pull-pin grenade widely used by the U.S. Army and Marine Corps. Pulling the pin in the grenade's fuze (the M213) releases the spoon and the hammer, which hits the primer at the top of the fuze body initiating the firing train. This fuze train is simple and has functioned well and reliably in grenades for decades. Unfortunately, it also has major safety issues. Any unwanted stimulus that causes the primer to function, like fire, initiates the entire fuze train. The large quantities of primary explosive in the detonator can also be detonated by external stimulus with enough energy to function the entire grenade. These problems are exacerbated when many grenades are in the same location, through sympathetic detonation. With the new design of grenade the body, heating tests were conducted on inert wax-filled M67 hand grenades and empty M67 hand grenades to see if grenade halves would separate when heated.
