The single prototype tank built by Chrysler (Detroit Tank Arsenal) in the summer of 1944 that had a 90mm gun T26 turret mounted on an M4(105) chassis. The T26 Pershing and M4 Sherman tanks had the same turret ring. The project was canceled by the Ordnance Dept. after it became apparent that this tank still needed to be tested, would not likely arrive in the combat theater any sooner than the T26 tank, and would most likely interfere with the T26 production effort.
