The Chieftain FV4201 was the main battle tank of the United Kingdom during the 1960s, 1970s and 1980s. A development of the Centurion and therefore a continuation of the British cruiser series, sharing a substantial commonality of parts with both its predecessor and successor. It was the “most formidable main battle tank in the world” with, at the time of its introduction in 1966 the most powerful main gun and most effective armour of any tank yet made.
