The base of the fuze proper is threaded internally to receive a zinc-alloy adapter. The base of the adapter is threaded externally to screw into the bomb. The top surface of the adapter is curved in order to receive the bottom of the cylinder. The cylinder con-tains the striker, a creep spring, and detonator cap. Two steel balls, held in place by the arming rod, immobilize the striker. The arming spindle extends up through the steel shaft and is threaded at the upper end. The vanes are attached to the arming spindle.

The safety pin is withdrawn. When the bomb is realesed, the vanes rotate and rise, along with the arming spindle. When the arming rod has risen 0.4 in., the steel balls are released, fall into the channel, and disengage the striker. The striker then rests on the creep spring. Upon impact, the creep spring is overcome; the striker and detonator con-tact and initiate the explosive train. The striker housing is spherical at the end and rests on the curved surface of the adapter. This assures that the fuze will operate, regardless of the position in which the bomb hits.
