Prototypes of the original 40-ton design, the Centurion Mark I, had 76 mm of armour in the front glacis, thinner than the then current infantry tank designs such as the Churchill which had 101 mm, but the glacis plate was highly sloped and so the effective thickness of the armour was very high — a design feature shared by other effective designs such as the German Panther tank and Soviet T-34.
