Development history

Sir John Carden designed the A9 as a cheap replacement for the Vickers mediums, and it was the first British tank with a hydraulically powered turret traverse. The 2-pdr was an excellent gun in 1940 but 14 mm of armour was not enough for any battlefield, and the two machine-gun sub-turrets robbed space while adding little. A9s fought in France in 1940 and in the Western Desert, where their reliability in the heat was poor, and were withdrawn by 1941.
