Armament 60 mm mortar White Phosphorus (WP) smoke bombs. Development By US Army Ordnance. Description The M527 fuze is generally similar to the M525 and M526 series fuzes, except that it is intended for use only in WP mortar bombs. The body materials of the M527 series are also different from the others. The M527 and M527A1 have plastic bodies, while the M527B1 and the M527A1B1 have aluminium bodies. Functioning is identical to the M525 and M526 series fuzes. The heads of these fuzes contain a spring-loaded
striker, direct-acting firing pin, and a clockwork mechanism to delay arming to a safe distance from the muzzle of the mortar. The head is threaded into a body of plastic or aluminium (dependent upon model). The body contains a cylindrical slider to position the detonator, a booster lead charge, and a small tetryl booster charge carried in an intrusion within the base of the fuze. Positive safety for shipment and handling is provided by a safety wire and pull wire. Manufacturer US government contractors.
