Armament US M1, M29 , M29A1 , and M252 81 mm mortars and other medium- and high-pressure mortars. Development By US Army, based upon British designs for the L16 mortar. This round is no longer in production in the US, nor is it held in US stockpiles. Description This is an elongated, streamlined bomb of modern type, but is unusual in that it does not employ an obturating ring nor any gas check grooves. It relies instead entirely upon accurate machining of the bourrelet to obtain the requisite windage and gas
checking performance. The effect of this can be seen by comparing the ballistic performance with that of the M374 design, which employs an obturating ring. The M362 bomb is of forged steel, the M362A1 of pearlitic malleable iron (PMI). The body is threaded at the nose for a fuze and has a threaded spigot at the rear to which the fin assembly is screwed. This is of light alloy and consists of a tapering tailboom and a drum-type fin assembly, that is, six fins around the ends of which is a circular shroud. A percussion primer is fitted into the end of the tailboom and there is an ignition cartridge inside the upper end, beneath the gas escape holes. The secondary charges are attached alongside the tailboom, over the gas escape holes, and retained by spring clips. M362 is obsolescent in US service. Manufacturer US government contractors.
