context_page_description: The Ordnance QF 20 pounder was a British 84 mm tank gun. It was introduced in 1948 and used in the Centurion main battle tank, Charioteer medium tank, and Caernarvon Mark II heavy tank. The 20 pounder was designed to replace the Ordnance QF 17 pounder, which had proven itself effective in World War II. However, once the 20 pounder gun was found to have inadequate performance against the Soviet T-54, the gun was mostly replaced in service by the larger calibre 105 mm L7 gun.
