Initially specified before the outbreak of the Second World War the (General Staff designation) A20 was to be the replacement for the Matilda II and Valentine infantry tanks. In accordance with British infantry tank doctrine and based on the expected needs of World War I-style trench warfare, the tank was required to be capable of navigating shell-cratered ground, demolishing infantry obstacles such as barbed wire, and attacking fixed enemy defences; for these purposes, great speed and heavy armament was not required.
The vehicle was specified initially to be armed with two QF 2 pounder guns each located in a side sponson, with a coaxial BESA machine gun. A third BESA and a smoke projector would be fitted in the front hull. The specification was revised to prefer a turret with 60 mm of armour to protect against ordinary shells from the German 37 mm gun. Outline drawings were produced based on using the A12 Matilda turret and the engine of the Covenanter tank. Detail design and construction of the A20 was given to the Belfast shipbuilders Harland and Wolff who completed four prototypes by June 1940. During the construction period the armament was reconsidered which including fitting either a 6 pounder or a French 75 mm gun in the forward hull. In the end a 3-inch howitzer was chosen.[2][3] The A20 designs were short-lived however, as at roughly the same time the emergency evacuation of the British Expeditionary Force from Dunkirk occurred.
At 43 tons, with a 300 hp Meadows engine, the A20 had limited power. Vauxhall were approached to see if they could build the A20 and one example was sent to Vauxhall at Luton to see if they could provide an alternative engine. To this end they developed a flat 12 petrol engine.
