Comparing: Excelsior vs. M22 Locust vs. T-127

At the end of 1942, the Churchill tank's armament was deemed insufficient. New tanks, the A31, A32, and A33 were developed as new infantry tanks. The A33 was developed by the English Electric Company. The LMS Company participated in the development of suspension for a new tank. Two vehicles, which differed greatly from each other, were manufactured. The A33 was set to go into production, but in 1943 the decision to cancel mass production of the Churchill was reversed, and the order for the A33 was not placed.

Initially designed for airborne operations, the vehicle was never used as such by the U.S.A. during World War II. In the absence of a good air delivery system, the Ordnance Department became less enthusiastic about any further development.

Developed together with the T-126 at Factory No. 174 during the summer of 1940. Vehicle development was suspended during the preliminary design phase and then discontinued due to problems with the V-3 diesel engine.
