In order to maintain its combat effectiveness, continuing modifications have led to numerous changes to main gun armament (e.g. NB: It was reputed that the performance of the 20 pounder gun (when firing APDS) was twice that of the 88mm gun of the German, Royal Tiger Tank. These changes resulted in the Mk 3 version of the vehicle. However, modifications to the original design were quickly made and the changes resulted in the adoption of a 20 pounder, fully stabilised, main gun and the replacement of the 20 mm cannon by a Besa mg (thus allowing the turret to be fully cast). They also featured frontal, glacis plate armour to deflect shot, a partially cast turret and Horstmann suspension. The early vehicles were equipped with a 17 pounder main gun and a 20mm Polsten cannon. It was soon recognised that the weight restrictions had to be lifted as the original specification could not be achieved within the 40 ton weight limitation. Six prototypes were developed before the end of World War 2, but arrived to late to take part in the war on German soil. In 1943, after a succession of unfortunate tank designs the British War Office commissioned a new specification calling for a tank with durability, reliability, a weight of 40 tons and the ability to withstand a direct hit from the German 88mm gun.
