The A2 Type submarine was a single submarine of the Imperial Japanese Navy during World War II, I-12, equipped with an aircraft. The design was similar to the A1 type submarine, except for weaker engines, but a longer range.
USS Ardent (AM-340) and USS Rockford (PF-48) sank a Japanese submarine on 13 November 1944. Postwar research reveals that it was most likely I-12.
