Overview
One of three B3-class cruiser submarines built under a naval shipbuilding program adopted just before the outbreak of World War II. I-56 entered service in June 1944. Initially armed with a 140 mm gun, the submarine retained this configuration only briefly. By October 1944, she had already begun conversion into a carrier for manned torpedoes.
