![]() This led to a series of up-gunned Crusaders mounting the 6-pounder. Only a small number were built.ĭelays in the A24 program led to demands to get the QF 6 pounder into service earlier. It was put into production anyway, but in service it proved underpowered. These arrived four months late, and by this time the design was already outdated. Six prototypes of the Cromwell were ordered for the spring of 1942. The designs were received and examined in January 1941, with Nuffield's A24 being declared the winner on 17 January. Their design was similar to the Nuffield, but with different suspension and tracks. The final entry was from Leyland and Birmingham Railway Carriage & Wagon (BRC&W). Nevertheless, as the design was based on the Crusader, it was expected it could be put into production rapidly. Nuffield submitted the A24, heavily based on its Crusader design and powered by its version of the Liberty engine, a V-12 design dating the late days of World War I and now thoroughly outdated. This would have had 75 mm of frontal armour, used a 12-cylinder Bedford engine, carried a crew of five and would have had the same suspension as the A22. Vauxhall responded with the A23, a scaled down version of their A22 Churchill infantry tank. The General Staff was aware that the Crusader would become obsolete, and in late 1940 they set out the specifications for a replacement tank, expected to enter service in 1942, fitted with the QF 6 pounder gun. The Centaurs were not used in combat except for those fitted with a 95 mm howitzer, which were used in support of the Royal Marines during the amphibious invasion of Normandy.ĭevelopment of the Cromwell and Centaur dates to 1940, as the Crusader tank was being readied for service. While the armoured regiments of the latter two divisions were equipped with M4 Shermans, the armoured regiments of the 7th Armoured Division were equipped with Cromwells. The tank equipped the armoured reconnaissance regiments of the Royal Armoured Corps, in the 7th Armoured Division, 11th Armoured Division and the Guards Armoured Division. The Cromwell first saw action in the Battle of Normandy in June 1944. The Cromwell and Centaur tanks differed in the engine used the Centaur had the 410 hp Liberty engine, the Cromwell had the significantly more powerful 600 hp Meteor Centaur hulls were converted to Cromwells by changing the engine. The Centaur tank was closely related to the Cromwell, both vehicles being externally similar. Later Cromwell development led to the creation of the competing Tank, Cruiser, Mk VIII, Centaur (A27L) design. Early Cromwell development led to the creation of the A24 Cavalier. ![]() The name "Cromwell" was initially applied to three vehicles during development. Further development of the Cromwell combined with a high velocity gun led to the Comet tank. The intended dual-purpose high velocity gun could not be fitted in the turret, so a medium velocity dual purpose gun was fitted instead. Named after the English Civil War-era military leader Oliver Cromwell, the Cromwell was the first tank put into service by the British to combine high speed from a powerful, reliable engine (the Rolls-Royce Meteor) and reasonable armour. The Cromwell tank, officially Tank, Cruiser, Mk VIII, Cromwell (A27M), was one of the series of cruiser tanks fielded by Britain in the Second World War.
