The AMX 50 (official designation) or AMX-50 was a French heavy tank designed in the immediate post Second World War period.
 It was proposed as, in succession, the French medium, heavy, and main battle tank and incorporated many advanced features.
 However, it was to suffer cancellation in the late 1950s due to unfavourable economic and political circumstances combined with delays in development.
The Heavy Tank T29 and Heavy Tank T34 were American developmental heavy tanks started in March 1944 to counter the appearance of the Tiger II at Normandy.
 The T26E3 Medium Tank (that entered service as the M26 Pershing), weighing around 45 short tons, was not considered heavily enough armed or armored to counter the Tiger II, which weighed closer to 69 tonne .
 The T29 was not ready in time for the war in Europe, but it did provide post-war engineers with opportunities for applying the engineering concepts learned in artillery and automotive components.
The M103 Heavy Tank (officially designated 120mm Gun Combat Tank M103) served in the United States Army and the United States Marine Corps during the Cold War.
 The last M103s were withdrawn from service in 1974.
 The M103 was the last heavy tank to be used by the US military as the concept of the Main Battle Tank evolved, making heavy tanks obsolete.
The Saint-Chamond, named after the commune of Saint-Chamond, was the second French heavy tank of the First World War, with 400 manufactured from April 1917 to July 1918.
 Although not a tank by the present-day definition, it is generally accepted and described as such in accounts of early tank development.
 Born of the commercial rivalry existing with the makers of the Schneider CA1 tank, the Saint-Chamond was an underpowered and fundamentally inadequate design.
 Its principal weakness was the Holt "caterpillar" tracks.
 They were much too short in relation to the vehicle's length and heavy weight (23 tons).
 Later models attempted to rectify some of the tank's original flaws by installing wider and stronger track shoes, thicker frontal armour and the more effective 75mm Mle 1897 field gun.
 Altogether 400 Saint-Chamond tanks were built including 48 unarmed caisson tanks.
 The Saint-Chamond tanks remained engaged in various actions until October 1918, belatedly becoming more effective since combat had moved out of the trenches and onto open ground.
 Eventually the Saint-Chamond tanks were scheduled to be entirely replaced by imported British heavy tanks.
The "ARL tracteur C", or ARL Char C, was a French super-heavy tank developed during the late Interbellum by the "Atelier de Construction de Rueil" (ARL) company.
 A full-scale wooden mockup was halfly produced, but the project was terminated in favor of FCM F1, a directly competing design, which proved to be superior design.
 The vehicle was meant to be extremely heavy and for that time period, very heavily armored.
 ARL C was intended to be very long to fill up the requirement of having a long tank that could cross trenches up to 7 meters wide.
 The tank was multi-turretted like FCM F1; however, unlike FCM F1, ARL C had the main turret in front of the very long hull right behind the secondary turret, not in the back of vehicle.
 The development path of the ARL C was extremely complex, due to the existence of a number of parallel super-heavy tank projects with overlapping design goals, the specifications of which were regularly changed.
 For each project in turn several companies submitted one or more competing proposals.
The Char 2C, also known as the FCM 2C, is a French heavy tank, later also seen as a super-heavy tank, developed during World War I but not deployed until after the war.
 It was, in physical dimensions, the largest operational tank ever made.
The T110 Tank was a cancelled heavy tank project from the 1950s, which was due to replace the M103 heavy tank.
 Restrictions were placed on the vehicle sizing as the tank was supposed to pass through the narrow tunnels of the Bernese Alps, none of which actually met the restrictions.
 but did not enter service due to the redundancy of another Heavy tank.
 It was intended to be built by Chrysler, but no vehicles were ever manufactured.
The FCM F1 was a French super-heavy tank developed during the late Interbellum by the "Forges et Chantiers de la Méditerranée" company.
 Twelve were ordered in 1940 to replace the Char 2C, but France was defeated before construction could begin, a wooden mock-up being all that was finished.
 The FCM F1 was large and elongated, and had two turrets: one in front and one in the back, with a single high-velocity gun in each turret.
 The rear turret was higher so it could shoot over the first one.
 The vehicle was intended to be heavily armoured.
 Its size and protection level made it by 1940, at about 140 tons the heaviest tank ever to have actually been ordered for production.
 Despite two engines its speed would have been low.
 The primary purpose of the tank was to breach German fortification lines, not to fight enemy tanks.
 The development path of the FCM F1 was extremely complex, due to the existence of a number of parallel super-heavy tank projects with overlapping design goals, the specifications of which were regularly changed.
 For each project in turn several companies submitted one or more competing proposals.
The Heavy Tank T30 was a World War II American tank project developed to counter new German tanks, such as Tiger I, Tiger II, and the Jagdtiger or Soviet heavy tanks, such as IS-1 or IS-2.
 The T30 was designed at the same time as the T29 Heavy Tank.
The ARL 44 was a French heavy tank of which the development started just before the end of the Second World War.
 Only sixty of these tanks were ever completed, from 1949 onwards.
 The type was already phased out in 1953.
