Almost immediately after the M4 Sherman was standardized, the US Ordnance Department started work on a successor. Authored By: Staff Writer | Last Edited: Although Ordnance began work on the T20 medium tank series as Sherman replacements, ultimately the Army decided to minimize production disruption by incorporating elements of other tank designs into the Sherman. The main differences between the T20, T22 and T23 lay in the choice of transmission. Ultimately the T21 concept was superseded by the T24 program, which was standardized as the M24 Chaffee. T20 Medium Tank – amerykański prototypowy czołg średni opracowany podczas II wojny światowej, będący pierwszym z serii pojazdów (T20, T22, T23), opracowanych w celu zastąpienia czołgów M4 Sherman.. Prace nad projektem rozpoczęte zostały w 1942 roku. [2]. In an attempt to rectify this, two further variants were ordered, the T23E3 with torsion bar suspension and the T23E4 with horizontal volute suspension. The T23E4 was cancelled before the design was completed, but the T23E3 prototype was completed and the Torsion bar suspension was found to have reduced the ground pressure by 20% compared to the T23. This version was cancelled and the turret used on the T22E1. The T22 was built by Chrysler with a different transmission. The Design was classified "limited procurement" in May 1943 and 250 T23's were ordered, although the design was never standardized or issued to front line units. Although it’s armorless, in skilled hands this tank becomes a real beast due to its speed, gun, view range, and decent camo-ratings. [1] The new project was started on the 25 May 1942, it was originally designated M4X. With the need for a new light tank, representatives of the Ordnance Department and the Armored Force held a conference at Fort Knox on August 18th, 1942. where it was decided that they should use the new T20 medium tank as a basis for the light tank.

The vehicle had a crew of five, a weight of 35,100 kg, used the same 474 hp, Ford GAN V8 engine as the earlier T23 Medium Tank, and had a top speed of 48 km/h.

The first prototype was produced in May 1943, and trials went on until 1944. The T23 was not adopted for service partly because of its untried transmission system and partly because the design had poor weight distribution and excessive ground pressure. However, the request was rejected and neither design was ever mass-produced. However, this model never saw mass production. Successive evolution of the basic design culminated in the M26 Pershing. Big, tall, boxy and clunky, it looks like the lovechild of the T1 Cunningham and an industrial air-conditioning unit. Intended as a replacement for the M4 Sherman tank, it features a rear transmission that gives it a much lower profile than the Sherman series, as well as the 76 mm gunfor additional anti-tank firepower. The T23 Medium Tank was a prototype tank that was produced in limited numbers by the United States during World War II.. What makes T20 … The driveshaft used in the M3 & M4 vehicles forced the turret to be mounted higher increasing the vehicle height. Media in category "T20 Medium Tank" The following 3 files are in this category, out of 3 total. The Medium Tank T20 was part of a series of medium tanks designed by the United States during the Second World War, to be the successor to the M4 Sherman. The engine was a V-8 supplied by Ford. Its availability was such that the tank made up many foreign tank stocks during and after the war with the last known frontline examples not retired until the 1960s/1970s. The vehicle was not approved for mass production, but subsequent prototypes, the T22 and T23, were created on the basis of this development. Motor Ford GAN V8 s hydrodynamickým měničem momentu, převodovkou typu Hydra-matic a podvozkem s horizontálním spirálním pérováním, vybavený 76 mm kanónem M1. The T22E1 version tested an autoloader, which eliminated the need for a human loader, reducing the turret crew and allowing for a smaller turret. The first prototype was produced in May 1943, and trials went on until 1944. The Ordnance Department would later suffer almost equal difficulty convincing the AGF to accept the upgunned versions of the Sherman with the net result that not a single 76 mm armed Sherman was in service in time for D-Day, even though they could have been available months earlier. There was only one T22 constructed.
