Common card · No. 386985

The Royal Ordnance L11A5, officially designated Gun, 120 mm, Tank L11, is a 120 mm L/55 rifled tank gun design. It was the second 120 mm calibre tank gun in service with British Army, the first of which was the Royal Ordnance OQF 120mm Tank L1. It was the first of NATO's 120 mm main battle tank guns which became the standard calibre for Western tanks in the later period of the Cold War. A total of 3,012 of the L11 guns were produced by 2005. The list price was US$227,000 in 1990. The L11 was developed by Britain's Royal Ordnance Factories to equip the Chieftain tank as the successor to the 105 mm L7 gun used in the Centurion tank and the heavy Caernarvon tank. It was also used on the Challenger 1, which replaced the Chieftain in British and Jordanian service. The weapon has been superseded by the L30 series 120 mm rifled tank gun.
