DESCRIPTION:

This fuze is a very simple impact type fuze. No striker is incorporated in the assemb-ly, the fuze relying on the shock of impact to detonate the explosive filling. The fuze consists of a hollow fuze body, with a thin sleeve filled with lead azide located in the nose portion. Below the lead azide sleeve is a thin aluminum container filled with C.E. (tetryl). This is followed by a slightly larger aluminum container, stemmed with C.E. in three increments. The latter container is closed with a tin-plate cone, with the closed end of the cone pointed inwards. A thin brass dished washer is located between the flange of the azide sleeve and the internal shoulder in the fuze body, and a thin brass or tinplate disc separates the two C.E. containers. The fuze is closed by crimping over the lower end of the fuze body.

OPERATION:

On impact against a hard target the lead azid sleeve fires and detonates the C.E. in the two containers, exploding the main charge of the rocket shell.

REMARKS:

(1) This fuze was originally designed for use in the 95 mm and other hollow charge gun projectiles, the con in the base of the fuze focusing the detonation to the main charge in the shell.

(2) The fuze has no safety devices incorporated, but has been proved safe against normal rough usage and dropping tests and will not function reliably at striking veloci-ties below 500 ft/sec.
