Comparing: FV201 (A45) vs. Black Prince

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.

Developed from 1943 through 1945 on the basis of the Churchill tank. It featured a wider and elongated hull to carry the upgraded turret with a 17-pounder gun. A total of six Black Prince prototypes were produced from 1944 through 1945. A few vehicles underwent trials but never saw action.
