The T57 Heavy Tank is an American tier 10 heavy tank.

A project of a heavy tank with an oscillating turret and automatic loading. Developed from 1951. Experimental turrets for 120 mm and 155 mm guns were manufactured by 1957. However, the project was deemed unsuccessful and the development was discontinued.

The T57 Heavy Tank is a tier X heavy tank in the American tech tree. Unlike the T110E5, the T57 is armed with a 4 round auto loader much like the AMX 50B. Apart from that, the T57's gun is nearly the same as the T110E5's one. The T57 is less mobile than the AMX 50B, however, it has better armor and a smaller profile. Its armor isn't as good as that of the T110E5, but it can bounce shots if angled correctly. The reload on this tank is really outstanding, only needing about 22 seconds to load the magazine and about a 2 second delay between shots, giving the gun amazing burst and DPM potential. Use the quick clip reload to your advantage and help your team deal massive damage to the enemy and this tank will be a force to be reckoned with.

The T57 Heavy Tank marks the end of the American autoloader equipped tank line.

Historical Info

T57 was a heavy tank developed in the U.S. in the mid-50's, Is a slightly modified version of the US T43E1 prototype that further evolved into M103 tank.

Development history

T58 prototype version fitted with a 155 mm gun in oscillating turret

In October 12, 1951, a decision was made to develop a prototype of a heavy tank with an oscillating turret, a new idea at the time invented by the French AMX company, and adopted on a highly successful AMX 13 light tank, and no so successful AMX 50 series of heavy tanks. New American tank, designated T57 (according to the American post-war terminology - "120-mm gun tank T57“), was based on the chassis of the T43 tank (prototype that further evolved into M103) with a brand new oscillating turret that hosted a powerful 120 mm T123E1 gun.

Oscillating turret

The oscillating turret design, lacking a conventional gun-mantlet, is in two separate parts, with an upper and lower part connected by two hinge bolts or pivots, the gun being fixed within the upper section. The horizontal movement of the gun, traversing, is conventional, but the vertical movement, elevation, is achieved through the pivoting of the entire upper section with respect to the lower section. This method of elevation has two main advantages. Firstly it allows for a smaller turret volume, as no internal space is needed for the vertical movement of the gun breech. Secondly, it allows the use of a relatively simple auto-loader fed by multiround magazines, achieving a very high rate of fire for as long as the magazines were loaded. Automatic loader was located in the back of a massive tower, and consisted of the feeder drum with 8 rounds. The drum was loaded by a hydraulic actuator, and the commander or gunner could pick three different types of ammunition. Spent cartridges were ejected through a special hatch on the roof of the turret.

Design flaws

Main armament of the tank was 120 mm T123E1 gun with the rifled barrel, and placing such a big, powerful and heavy weapon into the oscillating turret was plagued by various problems. Handling the immense recoil of the gun, and stabilizing the heavy turrets were among the issues that were never compleatly solved. Tank had the crew of 4, where loaders job was to reload the drum after all round have been fired. The tank carried a total of 10 additional rounds in the ammo rack, making a total ammo load to 18 rounds. Another issues were limited gun elevation (due to the back of the turret movement being limited by the hull), problems with ammo protection at certain angles (oscillating turret doesn't have mantlet that solves this problems on classic turrets) and the lack of protection against radiation and weapons of mass destruction, which was considered very important back in the fifties and sixties.

Fate

The development was very slow and interest in the tank started to fade. Changing priorities in favor of the development of small, aero transportable tanks led to the cancellation of the project in January 1957, before the prototype reached operational status and could be tested. No photos of the assembled prototype T57 with 1200 gun has survived.
