Comparing: FV201 (A45) vs. Tiger 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 the Tiger I was started in 1937 by the Henschel company. Mass production began in 1942, with an eventual total of 1,354 vehicles manufactured. The tank first saw combat in the fighting for Leningrad, and Tigers were at the forefront of battles from Tunisia to Kursk. Although production was discontinued in the summer of 1944, the Tiger I continued to see action until the end of the war.
