T78 historical reference
This vehicle project, using the chassis of the T24 light tank, was proposed in July 1943. The vehicle was to feature the 90 mm gun from the M36 tank destroyer. The U.S. Armed Forces requested the completion of trials and improvements to the chassis before converting the vehicle to a tank destroyer, but the program was discontinued in August 1943, in spite of successful trials by the T24 tank. No prototypes were built.
