Fuze Protector Mk 1 Mod 0

General: The Fuze Protector Mk 1 Mod 0 is designed to prevent damage by the cata-pult bridle to Nose Fuzes AN-M103, all Mods, AN-Mk 219, all Mods, and Mk 243, when these fuzes are in 500-pound or 1,000-pound G.P. bombs installed on the wing racks of F6F-type aircraft which are to be catapulted. It can also be used in connection with me-chanical time fuzes and the modified case-locking bushing for Fragmentation Clusters M28 and M29 Type.

Description: The Fuze Protector Mk 1 Mod 0 consists essentially of two pieces of 16-gauge steel five inches wide, bent into semicylinders of seven-inch diameter and one center plate of 16-gauge steel. Each semicylindrical piese has three slots 0.562 inches wide and 1.562 inches deep cut into it. At the bottom of the two slots on either side of the center slot, a ½-inch piece of metal is bent inward to form a stop. When installed, the two semicylindrical pieces are joined together by hinges (arming wires act as hinge pins) to form a cylinder.

Operation: The protector remains in place until the bomb is released. The arming wi-res are then pulled from the piano hinges of the protector. The two semicylindrical pieces then fall away from the bomb. The center plate remains in place between the fuze and the bomb.
