developed alongside the A9 cruiser tank, and was intended to be a heavier, infantry tank version of that type. In practice, it was not deemed suitable for the infantry tank role and was classified as a "heavy cruiser". It served briefly in World War II.

History and specifications

The A10 was developed by

Sir John Carden Sir John Valentine Carden, 6th Baronet MBE (6 February 1892 – 10 December 1935) was an English tank and vehicle designer. He was the sixth baronet of Templemore, County Tipperary, from 1931. Work Born in London, Carden ran a company from 1 ...

in 1934 by the adaptation of his A9 design. The A10 specification called for armour of up to standard (the A9 was ); a speed of ) was acceptable. The two sub-turrets present on the A9 were removed, and extra armour bolted onto that already present on the front and sides of the hull, along with all faces of the turret, providing approximately twice the armour in most areas. The A10 was two tonnes heavier than the A9, but used the same engine, and as a consequence the tank's top speed was cut from to . The turret armament consisted of a QF 2-pounder (40-mm) gun and a coaxial .303

. For the production version, there was a 7.92 mm BESA machine gun mounted in the hull in a barbette to the right of the driver. This was added to give extra firepower, but at the expense of simplicity - the Vickers and the BESA using different ammunition. The tank had a crew of five (Commander, gunner, loader, driver and hull machine gunner). There was no separation between the driver's compartment and the fighting compartments. The prototype ("Tank, Experimental A10E1") was completed in 1936, a few months after the A9 prototype.AFV Profile No. 6 p3 Carden had died in an air crash in 1935 and development was slower than expected. In 1937, the A10 was dropped as an infantry support tank, but in 1938 it was decided to produce an order of 75 as an interim "heavy cruiser". The A10 was accepted for service - initially as "Tank, Cruiser, Heavy Mk I" and then "Tank, Cruiser A10 Mk I" and finally "Tank, Cruiser Mk II". Production was ordered in July 1938. Total production was 175 vehicles, including the 30 CS versions (see below); 45 were built by Birmingham Railway Carriage & Wagon Company, 45 by Metropolitan-Cammell, 10 by

. In late 1939, another order was placed with Birmingham Railway Carriage & Wagon Company, this time for a larger order of 75 vehicles. Entering service in December 1939 the tank was something of an oddity, it had been intended to sacrifice speed for armour like an Infantry tank but was still relatively poorly armoured and not effective.

This weapon was derived from a World War I field howitzer, the QF 3.7-inch mountain howitzer. It was not related to the 3-inch (76 mm) howitzer used in later British tanks in the Second World War, which was itself replaced by a howitzer in the later versions of the Churchill infantry tanks and all CS versions of the Centaur and Cromwell cruiser tanks. British doctrine was that the CS tank was to provide smoke cover in advances or retreats and hence many more smoke rounds were carried than HE.Bovington accession record
