Comparing: FV201 (A45) vs. Caernarvon vs. Centurion Mk. I

Developed starting in 1944 by English Electric as a possible replacement for the A43 Black Prince. Some components were unified with the A41 Centurion. In 1948 trials of a prototype were started. The prototype mounted a Centurion Mk. II turret and a 17-pounder gun. Due to changes in Armored Forces policy and doctrine, development proceeded no further. However, the design later served as a basis for several post-war heavy tanks.

Development of this infantry support tank started in 1944. The first prototype was ready for trials in 1952. A total of 21 tanks were manufactured but never entered service. Some of the vehicles were later converted into the Conqueror heavy tanks.

Development of the Centurion started in 1943. The vehicle was designed as a "universal tank" to replace existing infantry and cruiser tanks. The Centurion was the first British vehicle that featured sloped armor plates. The tank entered service in 1947. A total of 100 vehicles of this series were manufactured from 1945 through 1946.
