Armament US M1, M29 , M29A1 and M252 81 mm mortars and other medium- and high-pressure mortars. Development By US Army, as a replacement for earlier practice bombs. Description Unlike other mortar rounds, the components of this round are issued separately to facilitate reuse and the replacement of damaged or worn parts. The bomb consists of a steel body threaded at the nose for a dummy fuze and at the rear to accept a tailboom and fin unit. The latter contains a propulsion cartridge inserted into the tailboom, and
a smoke cartridge inside the upper part of the tailboom; there is no connection between these two items. On firing, the propulsion cartridge provides the necessary thrust; on striking the ground an inertia firing pin in the smoke cartridge fires the smoke mixture. The smoke escapes from vents in the tail tube and marks the point of impact. The bomb can then be recovered and the propulsion and smoke cartridges can be replaced, allowing the bomb to be reused. Manufacturer US government contractors.
