Description
This fuze consists of an aluminum alloy fuze body with an ogival external contour. A thin brass cup is crimped over the forward end of the fuze body, which also is threaded to receive a black metal shipping cap. A CE booster is housed in a magazine, which threads into the base of the fuze.
A centrally located striker extends the full length of the fuze. A mushroom shaped pressure plate is fixed to the top of the striker by a split pin. The lower end of the striker terminates in an integral firing pin, which extends into a blind hole in the detonator shutter, retaining the detonator in the offset position when the fuze is unarmed. A compressed spring separates the pressure plate from the forward end of the fuze body and tends to force the striker and plate upwards. This upward motion of the striker is prevented until after firing by a half round rotary detent, which engages a slot cut in the striker spindle.
This fuze was designed to replace the No. 721 Mks IIs and III, when used in the “Land Mattress”, but its use may be extended to include the 5 inch (HE Shell) “Sea Mattress", and the 60 lb F. Shell, No. 1 Mk I for the 3 inch Aircraft Rocket.
