Armament UK L16 , US M242 mortars and similar high-pressure types. Development By RARDE as the standard projectile for the L16 mortar. Description The L36 bomb was the progenitor of the streamlined, plastic obturated modern bomb. It was designed to produce the maximum number of fragments of optimum size and was manufactured from spheroidal graphite cast iron. The polycarbonate sealing ring admits sufficient windage for loading but expands and seals under the gas pressure of firing. The ring also centres the bomb
to reduce yaw at the muzzle. There were two charge systems developed, Mk 4 and Mk 5. The Mk 4 system is in use with the British Army, the Mk 5 with the US Army (M821). The Mk 4 has six equal secondary charges, while the Mk 5 has four equal secondary charges. The maximum charge gives the same range with either system.
