Development history
A6 'Sixteen tonners '
In 1926, the British War Office wanted to replace their existing Mark II tanks with a new design. One of the requirements was a weight limit of 16 tons, which led to the nickname "16-tonners". The result was called A6, of which three prototypes were constructed. Testing showed deficiencies in the suspension and the gunnery arrangements. The vehicles were tested until 1928. These vehicles were the first ones to use the new Wilson epicyclic steering (the predecessor Merrit-Brown gearbox).[1]
Medium Mark III
The disappointments in the A6 design led to that a new design, the "Medium Mark III", was being constructed in 1930.[2] It was similar to the A6 design but featured a new turret and improved armor. Still, the designed suffered from its bad suspension design. Three Mark IIIs were built, one by Vickers and two by the Royal Ordnance Factory at Woolwich. However no orders followed due to its high price.
