However, it was decided that resources for both manufacture and shipping would be better spent on medium tanks, so they took another long look at the vehicle.... They deemed the internal layout unsatisfactory, the turret too small for further development, the 3" gun as obsolescent, at least for a heavy, and the drive train was unreliable for prolonged use.
Of the 5000 vehicles planned, the 40 built were exentsively used for trials, results being used in the design of the M26 Pershing. This vehicle is to be found in the Aberdeen Proving Grounds.
