DEUS VULT!!!

Cruiser Mk VI or A15 Crusader was one of the primary British cruiser tanks of the early part Second World War and perhaps the most important British tank of the North African Campaign. The Crusader's mobility made it a favourite of British tank crews and its Ordnance QF 6 pounder main gun made it more than a match for the early Panzer III and Panzer IV tanks it faced in combat.

Retained in service because of delays with its replacement, by late 1942 the lack of armament upgrade combined with the presence of Tiger I Tanks among the Afrika Korps and overheating problems caused by the high temperatures of the desert, led to the design being phased out in favour of the new US-supplied Sherman medium tank. The next British cruiser in combat would be the Cromwell heavy cruiser.

In 1938, Nuffield Mechanization & Aero Limited produced their A16 design for a heavy cruiser tank based on Christie suspension. Looking for a lighter and cheaper tank to build, the General Staff requested alternatives. To this end the A13 Mk III cruiser tank design which would enter service as the "Tank, Cruiser Mk V" and known in service as "Covenanter" was designed.

Nuffield were, in 1939, offered the opportunity to take part in the production of Covenanter. Nuffield, however, preferred to work on its own version of the A13—though they still provided design work for the Covenanter's turret. This new tank was adopted as "Tank, Cruiser, Mk VI Crusader", under General Staff specification A15. Although Crusader is often referred to as an improved version of the Covenanter, in fact it was a parallel design.Both tanks were ordered "off the drawing board" without building prototypes first. Despite a later start, the pilot model of the Crusader was ready six weeks before the first Covenanter.

Unlike earlier "Christie cruisers"( A13, Marks III and IV and the Mark V Covenanter ) that were built with 4 road wheels, Crusader had five road wheels each side to improve weight distribution in a tank that weighed almost 20 tons instead of the 14 tons of the previous cruisers. The 32 in (810 mm)-diameter wheels were of pressed steel with solid rubber tyres. The hull sides were built up of two separated plates with the suspension arms between them.It had a different engine from the Covenanter, different steering system and a conventional cooling system with radiators in the engine compartment. At the left hand side of the front hull—a place occupied by the engine radiator in the Covenanter—was mounted a small hand-traversed auxiliary turret armed with a Besa machine gun. The auxiliary turret was awkward to use and was often removed in the field or remained unoccupied.

Both the A13 Mk III and the A15 designs used the same main turret. The turret was polygonal—with sides that sloped out then in again—to give maximum turret space on the limited turret diameter. Early production vehicles had a "semi-internal" cast gun mantlet, which was quickly replaced in production by a better protected big cast mantlet with three vertical slits—for the main gun, for a coaxial Besa machine gun and for the sighting telescope. There was no cupola for the commander who had instead a flat hatch with the periscope mounted through it.

The main armament, as in other British tanks of the period, was balanced so the gunner could control its elevation through a padded shaft against his right shoulder rather than using a geared mechanism. This fitted well with the British doctrine of firing accurately on the move. When it was understood that there would be delays in the introduction of successor heavy cruiser tanks—what would become the Cavalier, Centaur and Cromwell—the Crusader was adapted to use the 6 pounder gun.
