Nuffield's first tank was the
Cruiser Mk III which came out of studies of a
Christie-designed tank which was obtained from the USA in 1930s. The first pilot vehicles were delivered in April 1937 and production vehicles, "A13 Mark I" from December 1938. A single prototype, the A16E1, was built but neither it nor the A14 design by
London, Midland & Scottish Railway was taken up and the project was cancelled in 1939. In 1939 the
Covenanter tank designed by LMS was ordered and Nuffield were approached about production but choose to develop their own design to meet the same specification using the Liberty and this went into service as the
Crusader tank. While initially effective, in the harsh North Africa campaign the Crusader got a reputation for being unreliable. They were withdrawn from front-line service in 1942; Crusader III saw the introduction of the Mk. IV Liberty engine, fixing many of the reliability issues previously encountered. Nuffield Mechanizations followed this with the
Cavalier tank which also used the Liberty engine. Though the tank was put into production the power of the Liberty engine was limited and because of the increase in tank weight the Cavalier was not used in combat. The last tank the Liberty engine was produced for was the A27L
Centaur tank, effectively the same design as the
Cromwell tank but with less engine power. ==Bofors guns==
