The American program to create a replacement for the Medium Tank M4 was a mess by the end of 1943. Three types of medium tanks were being tested in parallel. These included the Medium Tanks T20 and T22. Two prototypes of each were built, and proven to be ultimately disappointing. There was also the Medium Tank T23. It turned out to be better than its competitors and even put into production, but it turned out that there were issues with using it. Finally, development of two more tanks was launched in May of 1943. This made for five medium tanks in development at the same time. This article will describe the fate of the Medium Tank T25, an intermediate vehicle.
Same thing with a bigger gun
The Medium Tank T23 had the highest priority as of the spring of 1943. A prototype was available before its competitors, and the electromechanical transmission was easy to handle and reliable, which could not be said about the planetary and mechanical gearboxes of the Medium Tanks T20 and T22. Because of this, a proposal to put the T23 into production was already tabled by May 1943. It seemed that this would be the best way forward.
