The T110 Tank was a cancelled heavy tank project from the 1950s, which was due to replace the M103 heavy tank. Restrictions were placed on the vehicle sizing as the tank was supposed to pass through the narrow tunnels of the Bernese Alps, none of which actually met the restrictions, but did not enter service due to the redundancy[clarification needed] of another Heavy tank. It was intended to be built by Chrysler, but no vehicles were ever manufactured. The tank was planned to be powered by a Continental Motors, Inc. AV-1790-3 engine powerplant delivering around 875 hp.

There were 5 different proposals before the T110 program was canceled, all fitted with a 120mm rifled anti-tank gun.


The third proposal of the T110, it would have been equipped with the gun in a casemate hull. The thickness of the hull was intended to be 305mm on the front part, 76mm on the sides and 38mm on the back.


The T110E4 was Chrysler’s response to the power pack issues in their T110E3 . The tank was planned to use an AOI-1490 engine from Continental Motors, Inc. located in the rear of the hull along with the transmission.


The T110E5 was the fifth and final proposal under the T110 program by Chrysler. In contrast to the previous designs, the T110E5 possessed a turret, although it retained the M58 120mm anti-tank gun. The strange shape and angling would have made the armour very effective at stopping antitank guns fired at the front of the T110E5.
