The A15 Cruiser Tank Mark VI Crusader was the primary British tank from spring 1941 until the American Sherman tank arrived.
The A15 was built by Nuffields and was ready by March 1940. By 1943, 5,300 Crusaders had been produced.
To reduce costs and production time, as well as vehicle weight, Nuffields used many of the components of the A13 series, including the Liberty engine and the Christie suspension.
Like the A13 series, the A15 had a welded turret, a riveted hull and an extra outer layer of armor.
The Crusader was rushed into production and, when in action, was not very reliable.
It saw action for the first time in June 1941 near Fort Capuzzo, Libya, where it performed well against Italian armor.
However, while it had a respectable speed, it was not a match for the German Panzer III or the German 3.46 inch (8.8 centimeter), 2.95 inch (7.5 centimeter) or 2.17 inch (5.5 centimeter) anti-tank guns.
In May 1943, the Crusader was withdrawn from the front line, but it continued to be used for training afterwards.
It was also converted for a number of special uses, which included:
- Crusader III, Anti-Aircraft (AA) Mark I – The turret was replaced by one Bofors 1.57 inch (40 mm) anti-aircraft mount
- Crusader III, Anti-Aircraft (AA) Mark II- This had a new enclosed turret with a twin 0.79 inch(20mm) Oerlikon AA cannon
- Crusader III, Anti-Aircraft (AA) Mark III – This resembled the Mark II, but the radio equipment was installed in the hull rather than the turret
- Crusader II, Gun Tractor Mark I – This had an open-topped box superstructure which transformed it into a fast tractor for a 17 pounder anti-tank gun and its crew
- Crusader with Anti-Mine Roller Attachment (AMRA) – Used to clear land mines
- Crusader Observation Post (OP) and Crusader Command – Extra radio and communications equipment, as well as a dummy gun, were added
- Crusader Armoured Recovery Vehicle (ARV) – Additional recovery equipment was added and the turret was removed
- Crusader Dozer – A winch and jib for working the dozer blade were added and the turret was removed.
