This fuze is diveded into two pieces which are threaded together. The upper piece is male threaded. The top of the upper portion is dome-shaped. A hole passes horizontally through the uppermost part of this dome to receive the split pin which holds the vanes in the unarmed position. Protruding from the shoulder of the upper housing is a hollow shaft with internal threads to receive the safety rod. The single arming vane is attached to this rod. The safety rod passes through the striker. The striker and detonator housing are rounded at the ends to give the effect of an "all-ways" fuze. The striker and primer cap are held apart by a creep spring when the fuze is armed. The base of the lower housing is threaded to receive the booster. The large booster is used.

The arming vane is folded over the dome of the fuze and secured there by a split pin. Upon the bomb's being released from the plane, the split pin is with-drawn and the vane flies out in the position shown in the drawing. In flight, the vane rotates and unscrews the safety rod, which eventually falls away. This releases the striker, which then rests on the creep spring. Upon impact, the striker and detonator cap overcome the creep spring and make contact. Since this is an "all-ways" arrangement, the fuze will detonate, regardless of the position in which the bomb lands.
