T20 - American Medium Tank, 1943
As soon as the M4 Sherman medium tank was being delivered to the US Army, a new design was sought to enhance the capabilities of the medium tank. In May of 1943, the first T20 prototype was produced, and would become one of a series of various test vehicles to meet the requirements of a new medium tank. It used an early version of HVSS suspension with the same tracks as the M4, and shared many smaller parts with the M4, ideally allowing for increased ease of production should the T20 be adopted. The rest of the tank was completely different from the M4, using a new Ford V-8 engine, a 76mm M1 main gun, and being considerably shorter. Following testing at Aberdeen Proving ground, the tank encountered numerous transmission failures and the project, as well as variant T20E3, was cancelled. This was also due to the fact that the T23 tank was already complete by January 1943, and was a much more promising vehicle overall.
This brick-built version of the T20 medium tank breathes new life into the prototype vehicle that eventually led to the M26 Pershing, and represents a new era of American medium tank development. The tank has a fully rotating turret, with elevating and depressing main gun, and articulating tracks with road wheels on pivoting bogies similar to the suspension of the real tank. This model also has a mounting point for a 3rd party brick version of the M2HB heavy machine gun for the commander.
