GENERAL:

This fuze is not threaded into the bomb nose, but is pushed down and held there by two spring loaded retaining balls which protrude from the side of the fuze. The fuze re-quires an adapter ring having an annular groove to receive the retaining balls.

OPERATION:

When the arming wire is withdrawn from the arming pin as the bomb is dropped, the arming pin is ejected from the fuze by the action of the  arming pin spring. The safety block holder than falls free of the fuze, and the safety block is ejected clear of the fuze and striker by its spring. On impact, the striker is driven into the fuze body, cutting the shear wire and impinging on the primer, setting off the upper detonator, and lower de-tonator successively.

EARLY DESIGN:

The early M108 did not have a safety block inserted between the striker head and fuze body, and was quite dangerous as a drop of only a few inches on a hard surface was enough to function the fuze. The M108 Modified is shipped with the safety block as shown in drawing.

REMARKS:

This fuze was designed for use in the M47 100 lb. Incendiary. It is being replaced by the AN-M126A1 in all bombs except the M75 Target Identification bomb.
