Over-all length

Over-all length of vanes

Width of fuze body

The nose of the fuze consists of a lug which is a part of the striker. The striker is threa-ded just below the lug in order to receive the arming vanes. The fuze body has a narrow shoulder, immediately beneath which are the threads which screw into the nose-fuze pocket of the bomb. A stop pin inserted in a channel in the striker prevents the spindle from turning with the arming vanes. The primer cap is located in the lower part of the fuze body, with another small charge of explosives. A creep spring separates the striker from the primer.

The safety pin is withdrawn when the bomb is dropped. The vanes rotate in flight and raise the striker. The striker then rests on the creep spring. Upon impact, the striker over-comes the creep spring, contacts the primer, and initiates the explosion.
