Two British warriors that didn’t see combat - the A38 Valiant (left) and the A33 Excelsior (right).
The A38 was possibly the worst tank the Brits ever conceived during the war. By the end of its development, the War Board deemed it to an abject failure in all categories. The A38 was supposed to meet the specification for a lightweight but heavily armored tank for use in the war in the Far East, but it proved to be an ergonomic failure. The sole A38 produced was retained by the School of Tank Technology, where students were treated to an inspection of it at the end of their course and invited to find fault. David Fletcher wrote of this: “One hopes they started early in the morning.”
The A33 was produced after the disastrous Dieppe Raid in August 1942. Looking back on the operation, there was concern that the Churchill infantry tank was slow and too unreliable and it was suggested that production of the Churchill stop in 1943 in order to manufacture more of the A27 Cromwell design which was performing well in trials. However the kinks in the Churchill were worked out before more than two experimental variants of the A33 were produced and the project was dropped.
