The I-6 was a further experimental development of the J1M (J2 class) long-range cruising submarine (Junyo sensuikan). She was completed at the Kawasaki yard in Kobe in 1935 and seems to have retained her seaplane facilities (a deck tube for the seaplane and an aft catapult) throughout her career.

She was deployed east of Oahu when war broke out, and put a torpedo into Saratoga on 11 January 1942, putting the carrier out of action and ensuring she would not be available for the Coral Sea and Midway operations. I-6 went missing on 30 June 1944 off Saipan, likely a victim of friendly fire following a collision with Toyokawa Maru.
