👉 Royal Ordnance L11 in the context of Chieftain (tank)

The FV4201 Chieftain was the primary main battle tank (MBT) of the United Kingdom from the 1960s into the 1990s. Introduced in 1967, it was among the most heavily armed MBTs at the time, mounting a 120 mm Royal Ordnance L11 gun, equivalent to the much larger specialist heavy tanks in service. It was also among the most heavily armoured, with up to 195 mm (7.7 in) that was highly sloped to offer 388 mm (15.3 in) thickness along the line of sight.

A development from the Centurion MBT, the Chieftain introduced the supine (reclining) driver position to British design allowing a heavily sloped hull with reduced height. A new powerpack and improved transmission gave it higher speed than the Centurion despite being heavier due to major upgrades to armour protection and the armament; this allowed it to replace both the Centurion and Conqueror heavy tank while performing their roles effectively.

Royal Ordnance L11 in the context of Royal Ordnance L7

The Royal Ordnance L7, officially designated Gun, 105 mm, Tank, L7, is the basic model of the United Kingdom's most successful tank gun. It is a 105 mm L/52 rifled design by the Royal Ordnance Factories, intended for use in armoured fighting vehicles, replacing the older QF 20-pounder (84 mm) gun mounted on the British Centurion tank. The successful L7 gun has been fitted on many armoured vehicles, including the Centurion (starting from the Mk. 5/2 variant), the German Leopard 1 and, in an altered design, as the M68 gun in several variants of the US M48 Patton and M60.

The L7 is a popular weapon and continued in use even after it was superseded by the L11 series 120 mm rifled tank gun, for some Centurion tanks operating as Artillery Forward Observation and Armoured Vehicle, Royal Engineers (AVRE) vehicles. The L7, and adaptations of it, can be found as standard or retrofitted equipment on a wide variety of tanks developed during the Cold War.

Royal Ordnance L11 in the context of Challenger 2

The FV4034 Challenger 2 (MoD designation "CR2") is a third generation British main battle tank (MBT) in service with the armies of the United Kingdom, Oman, and Ukraine.

It was designed by Vickers Defence Systems (now Rheinmetall BAE Systems Land (RBSL)) as a private venture in 1986, and was an extensive redesign of the company's earlier Challenger 1 tank. The Ministry of Defence ordered a prototype in December 1988. The Challenger 2 has four crew members consisting of a commander, gunner, loader, and driver. The main armament is a L30A1 120-millimetre (4.7 in) rifled tank gun, an improved derivative of the L11 gun used on the Chieftain and Challenger 1. Fifty rounds of ammunition are carried for the main armament, alongside 4,200 rounds of 7.62 mm ammunition for the tank's secondary weapons: a L94A1 EX-34 chain gun mounted coaxially, and a L37A2 (GPMG) machine gun. The turret and hull are protected with second generation Chobham armour, also known as Dorchester. Powered by a Perkins CV12-6A V12 diesel engine, the tank has a range of 550 kilometres (340 mi) and maximum road speed of 59 kilometres per hour (37 mph).
