EMPLOYMENT: This base fuze fits into one of the venturi of the German 15- cm and 21-cm Rockets. (See fig. 613.)

DATA:

Over-all length: 1.438 inches.

Maximum diameter: 0.536 inch.

No threads.

CONSTRUCTION: The body is made of a black colored plastic with an aluminum band around the shoulder.

Within the body is a igniter bridge from which runs two wires. One wire is connected to the aluminum band around the shoulder and the other to a metal disk in the base of the fuze. A black powder charge is located just above the igniter bridge.

ACTION: An electric current is passed through the fuze firing the igniter bridge. This, in turn, fires the black powder charge which sets off the propellant.

REMARKS: This fuze is to be replaced by the type ERZ 39 (B) which is manufactured from heat resistant materials. The distinguishing feature of this new fuze is the grey co-lor of the body.
