L9A1 51 mm light mortar


The L9A1 51 mm light mortar was a man-portable platoon-level mortar system used by the British Army from the late 1980s to 2007.
Ammunition for the 51 mm mortar has a small, ring-pull safety pin on the side of the nose-fuze. The fuze remains unarmed until the pin is withdrawn. Therefore, the safety pin must always be removed and discarded before a mortar shell is fired. A short range insert device allows the weapon to be used in a direct fire mode. Smoke, illuminating and high explosive bombs are available.
The 51 mm mortar replaced the World War II-vintage 2 inch mortar in the late 1980s. It was due to be phased out by the use of the 40 mm L17A2 UGL mounted on the L85A2; however operational experience has led to the decision to replace it with a 60mm Mortar. The Hirtenberger AG M6-895 60 mm Mortar was procured in 2007 as an Urgent Operational Requirement to replace the current 51 mm Mortar on current operations.
