DESCRIPTION. This is an electrically armed, mechanical tail fuze. A charging head is secured in the transverse fuze pocket of the bomb by locking and locating ring. This fuze pocket is merely a well to hold the charging head, and is not a full scale transverse fuze pocket. The wires from the charging head run along the inner wall of the bomb case to the tail through a pipe welded to the wall and end in a female electrical plug. A male plug is inserted into this and is connected by a double wire to an electrical squib in the rear of the mechanical portion of the fuze. This mechanical portion of the fuze, which consists of a fuze body, squib housing, gas cylinder, striker, locking balls, creep spring, and deto-nator holder, is shipped as a separate component in the packing box containing the bomb, and is placed in the bomb prior to loading in aircraft. (See fig. 148.)

OPERATION. On release from the aircraft, a charge of electricity is sent through the charging head to fire the electrical squib. The expanding gases produced by the firing of the squib force the gas cylinder up and off the fuze body releasing the striker locking balls. The fuze is now armed.

On impact the striker overcomes the creep spring and fires the detonator.
