Armament UK 51 mm mortar. Development Developed by RARDE in the 1960s as a replacement for the 2 in mortar. Description A bomb of somewhat unusual shape, the body is a straight taper from nose to tail, with a six-fin tail unit screwed into the end. The body is of aluminium alloy lined with a mild steel fragmentation coil. This is notched around its internal diameter so as to produce fragments of optimum size. An adaptor ring is crimped into the head of the bomb, retaining the filling and acting as a threaded seat
for the fuze. A plastic obturating ring fits into one of the crimps around the head to give gas sealing. The propelling charge consists of a single cartridge carried in the tail tube; there are no secondary charges. Manufacturer BAE Systems , Royal Ordnance Division.
