ww2dbaseThe Japanese Navy submarine aircraft carrier I-14 was commissioned in Mar 1945. She carried two M6A1 Seiran floatplanes, which were launched with a single catapult and were recovered using two folding cranes. She was one of the submarines meant to carry out surprise attacks deep in enemy waters, with the Panama Canal as the initial prime target. The target was later shifted to the US Navy anchorage at Ulithi Atoll in the Caroline Islands. She never saw combat before the war's end, however. She was surrendered at sea to the Americans on 27 Aug 1945. After being studied by the US Navy, she was sunk as a target just off Barber's Point, Oahu, US Territory of Hawaii in 1946. Her wreck was discovered by a a group from the Hawaii Undersea Research Laboratory and National Oceanic and Atmospheric Administration in 2009.
