1 History and specifications

The A9 was developed by Sir John Carden in 1934. Intended to succeed the Vickers Mark II . The great depression was still ongoing at the time, however, and the tank had a number of cost-cutting measures applied. First British tank to have a centrally-located turret. It was poorly armoured, however, with a maximum of 14mm at mostly vertical angles, and there were numerous shot traps .

There was no separation between the driver's compartment and the fighting compartments. As well as the turret armament, which consisted of a 2-pounder (40mm) gun and a coaxial Vickers machine-gun, there were two small turrets either side of the driver's compartment, each sporting one more machine-gun. Both these smaller turrets were permanently manned, which resulted in the tank having a crew of 6 (Commander, gunner, loader, driver and two machine-gunners).

The tank entered testing in 1936 and 125 were ordered in the summer of 1937. Originally a Rolls-Royce car engine was used, but this proved underpowered and was replaced by an AEC bus engine.

The later Valentine tank essentially used the same lower hull and suspension, though with considerably more armour.

The A9 weighed 12 tons, was 5.8 metres long, 2.65 metres high, 2.5 metres wide, and had a top speed of 25mph on road and 15mph off. Its maximum road range was 150 miles. 100 2-pounder rounds were carried, and 3000 rounds total were carried for the three Vickers machine-guns.
