The L9A1 51 mm Light Mortar is a man-portable mortar system used by the British Army. Smoke, illuminating and high explosive bombs are available. A short range insert device allows the weapon to be used in a direct fire mode. The 51 mm mortar, which replaced the World War II-vintage 2 inch mortar, was due to be phased out by the use of the 40 mm L17A2 UGL (Under-slung Grenade Launcher) mounted on the L85A2; however operational experience has led to the decision to replace it with a 60mm Mortar. The M6-895 60 mm Mortar has been procured as an Urgent Operational Requirement (UOR) to replace the current 51 mm Mortar on current operations.
