The FV4201 Chieftain was the main battle tank (MBT) of the United Kingdom from the 1960s into 1990s. When introduced, it was among the most heavily armed MBTs of the era, mounting a 120 mm Royal Ordnance L11 gun, the equal of the much larger specialist heavy tanks then in service.
The initial engine choice in 1954 for what was known at the time as "Medium Gun Tank No.2", later designated the "FV4201" and given the service name 'Chieftain', was a Rolls-Royce diesel V8, however during the Chieftain's design phase NATO introduced a policy in 1957 requiring all armoured fighting vehicles to have a multi-fuel capability.
The Tank Medium No. 2 Experimental Vehicle FV4202 also known as the 40-ton Centurion [1] was a technology test bed developed by British company Leyland Motors between 1955 and 1956. It was used to develop various concepts later used in the Chieftain main battle tank.

The design would use the new engine and transmission of the Chieftain tank then being developed. The development coincided with an agreement with India in 1961 to produce a tank design and help set up a factory there to produce it. The Vickers MBT Mk 1 was designed to be a simple, low-cost, but effective tank. [2]
The MBT-80 was to have a longer range, more mobility, and greater speed than prior tanks. [2] Two options were considered; the Honeywell AGT1500 gas turbine engine used by the United States's prototype XM1 Abrams tank, producing 1,500 hp, and a modified, turbocharged version of the Rolls-Royce CV12 diesel engine, also producing 1,500 hp.
