Comparing: Caernarvon vs. Tiger II vs. AMX 50 100

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.

The most heavily armored tank carrying the most powerful anti-tank gun. The vehicle's drawbacks included an overloaded suspension and engine-transmission group, as well as excessive general mass. When engaging enemy vehicles at long range, the Tiger II had an upper hand over any other vehicle in terms of the gun and armor protection. However, due to the excessive mass of the vehicle, relatively low durability of the engine and transmission, and small total number of vehicles built, the Tiger II did not have any significant impact on the course of war.

The AMX 50 100 heavy tank was a further development of the M4 project. The first prototype was built in 1949. The 55-ton vehicle featured a 100-mm gun in the oscillating turret. The prototype was tested with gasoline and diesel engines from 1950 through 1952. The vehicle never entered mass production nor saw service.
