I-56: Tier VIII Japanese Premium Submarine 1944

The second Otsu-Gata Type B3 submarine was commissioned in June 1944. I-56 took part in the defense of the Philippine Islands and engaged in the Battle of Leyte Gulf, during which she sustained damage. In 1944, she was converted into a Kaiten torpedo carrier. I-56 was lost in the course of the Battle of Okinawa, and the circumstances of her loss remain unknown.

Key Features

The main armament of the submarine is composed of six torpedo tubes with long-range torpedoes in the bow of the hull, as well as a 140mm main calibre gun with SAP shells, under direct player control. The sub has excellent surface manoeuvrability, but it is significantly lower underwater and has limited dive capacity. This makes long dives impossible for the I-56.
