The submarine I-14 was a large, seaplane-carrying submarine of the Imperial Japanese Navy of the AM type. 400 feet long and 40 feet high, it didn't see action in World War II. With a range of 21,000 nmi, it could carry two or three Aichi M6A Seiran bombers, whose wings and tail could be folded to fit into the sub.

I-14 surrendered at sea at the end of the war. It was one of five subs that were brought to Hawaii at war's end, then sunk off Oahu after U.S. technicians had studied their secrets. It was located in 2009 by a group from the Hawaii Undersea Research Laboratory and National Oceanic and Atmospheric Administration.

Modified “New Junsen Type”, of which only two units were completed. They Had markedly less powerful machinery than boats of their size normally have, because emphasis was given to great operating range rather than speed. Oil shortage and scarcity of high quality engine parts probably had an influence, too.

Their two seaplanes were stowed in a hangar before the conning tower. While the conning tower was slightly ofset to port, the hangar itself sat on centerline. The planes were launched on a rigid catapult that ran from the hangar up to the bow. They were retrieved by a retractable crane on the portside. These boats had a snorkeling tube, and their hulls were shielded against sonar by an anechoic coat. The coating consisted of a resilient rubber/sand mixture. It had a thin cement or plastic covering.

I-14 surrendered at the end of the war. The U.S. Navy brought her to Pearl Harbour for scrutiny, then scuttled her 1946.
