Comparing: O-Ho vs. T34

The O-Ho was a further development of the idea of a superheavy tank with improved armor protection. The vehicle had a good set of guns that allowed for all-angle fire. The project was discontinued due to the war ending. No finished prototypes were built and the vehicle never saw action.

Developed in 1945 as a modernization of the T30 heavy tank. The vehicle was equipped with the 120 mm T53 gun and the new Continental AV-1790 engine. The end of World War II lowered interest in heavy tank development, so the T34 never entered service. The prototypes were used in field trials.
