later be used in modified form for 76mm M4 variants. 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. 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.

drive similar to the M4 drive, and the T23 used an electric drive. All moved the transmission to the rear of the vehicle eliminating the need for a driveshaft running the length of the vehicle. The driveshaft used in the M3 and M4 vehicles forced the turret to be mounted higher increasing the vehicle height.
372:. However, the request was rejected and neither design was ever mass-produced. The Army did not consider it necessary to interrupt M4 production for a vehicle for which they did not perceive a requirement and the introduction of the 76 mm gun to the tank force was opposed by the Armored Ground Force.

supplied electric transmission with M4 tracks and VVS suspension. As with T20 and T22, three pilot models were ordered from
Detroit Arsenal with different armament T23 with 76mm, T23E1 with automatic 75mm and T23E2 with 3-inch gun. The 75mm and 3-inch designs were cancelled before completion but the

There was only one T22 constructed. The T22E1 was the T22 pilot vehicle re-equipped with the turret originally built for the T20E1. The 75 mm automatic gun was tested in this installation and gave a maximum rate of fire of 20 rounds a minute, but was abandoned in
December 1944 on the basis that

Work on T22 started in
October 1942 when Chrysler were contracted to build pilot tanks that were identical to the T20 including the Ford GAN V8 except for using the M4 Sherman transmission though rear wheel drive rather than positioned in the front of the Sherman's. Both vehicles were built by June

The design was classified "limited procurement" in May 1943 and 250 T23s were ordered; these were built between
November 1943 and December 1944 although the design was never standardized or issued to front line units. Production models featured the T80 gun mount and M1A1 76mm gun. The turret would

Starting with the T20, the
Ordnance Department initially developed three series of improved medium tank prototypes, the T20, T22, and T23. The main differences between the T20, T22 and T23 lay in the choice of transmission. The T20 used a torque converter fluid drive, the T22 a 5-speed mechanical
