Armament US M1, M29 , M29A1 and other medium-pressure 81 mm mortars. Development By the US Ordnance Department after Brandt originals. These rounds are out of production and no longer held in the US stockpile, but may be found elsewhere. Description This the oldest mortar ammunition design in the US inventory, having been introduced (as the M43 ) with the M1 mortar in the late 1930s. Subsequent modifications have been relatively minor and the bomb is still essentially the original Brandt design. It is a
teardrop-shaped forged steel bomb, with four gas check grooves at the bourrelet and a welded steel tail tube and fin assembly. The difference between the M43A1 and A1B1 bombs is confined to manufacturing details and has no operational significance. A propulsion cartridge is fitted in the tail tube and up to eight secondary increments fit between the tailfins and are secured by spring clips. These increments are in the form of leaves of smokeless powder contained in plastic envelopes. Although the round is obsolete in US service, it may still be encountered in other countries. Manufacturer US government contractors.
