Comparing: T14 vs. O-I Experimental

Developed between May 1942 and May 1943. Two prototypes were manufactured and tested. However, mass production was canceled, and T14 never became more than an experimental vehicle.

Development of this superheavy tank was initiated by Colonel Iwakuro from the Army Ministry of Japan. The project was carried out by the Mitsubishi company, therefore the vehicle became known as the Mi-To. In the army, the tank was designated the O-I. Details of the project are largely unknown.
