Description
This fuze is an adjustable delayed-arming type designed for use with projectiles fired from 4.2-inch mortars, 105mm and 155mm howitzers, 175mm gun and 8-inch howitzers against surface targets,
The fuze contains a radio continuous wave transmitter/detector with antennas and a power supply which performs the target detection function. A plastic nose cone is fixed to a rotatable metal setting ring which has a single index line. The setting ring is connected to a clockwork timing mechanism within the fuze sleeve which energizes the proximity element on approach to the target. In addition, a PD element is included to detonate the projectile on impact if desired, or if the proximity element fails to operate. Graduations from 5 to 100, representing seconds to target, and a PD set line are inscribed around the shoulder of the sleeve. On this model, the PD mark coincides with the 90 second proximity setting. The slot in the setting ring is for time setting only. Slots in the fuze sleeve are for the fuze wrench when assembling the fuze to the projectile. The fuze is shipped with the index mark alined with the 10 second mark on the fuze sleeve.
