O-I

O-I was the designation given to a proposed series of Japanese super-heavy tanks designed during World War II. The vehicle was planned to be very heavy and have a crew of 11. The complete history of the O-I is unknown, due to the “obscure” nature of the project and the limited documentation that survived post-war.
