The Tank, Cruiser, Mk VIII, Cromwell (A27M), and the related Centaur (A27L) tank, were one of the most successful series of cruiser tanks fielded by Britain in the Second World War. The Cromwell tank, named after the English Civil War leader Oliver Cromwell, was the first tank put into service by the British to combine a dual-purpose gun, high speed from the powerful and reliable Meteor engine, and reasonable armour, in a balanced package. Its design formed the basis of the A34 Comet tank.
It dates back to 1940 when the development started after the request of a successor for the Crusader cruiser tanks. The first design was the Mark VII Cavalier tank wich saw his debut in 1941. But during testing, it proved to have too many problems to be considered for use in combat which become an unsuccessful design. After that, in 1942 the Mark VIII Centaur was presented. A much better design than the Cavalier, but it still had some problems. Problems with the engine led to the Cromwell design which has the Rolls Royce Meteor engine, which was based on the famous Merlin engine used in the Spitfire. The first variants had the 57mm Ordnance Qf 6 Pounder but soon in late 1943 they were replaced by the much more powerful 75mm M3 gun from the United States of America. Low armour, low weight, low profile, good engine, powerful gun and a fast suspension, it made the tank a weak but powerful and fast tank which is not easy to hit! It entered the war in Normandy in 1944 and it was used until the end of the war. Until 1955 the Cromwell saw action. Atleast 3,000 Cromwells were built. Ingame we have the Cromwell Mk.IV, the most numerous variant with over 1,935 units produced.
