Two World War II Japanese submarines, designed with revolutionary technology to attack the U.S. mainland, have been discovered off the coast of Oʻahu. They are the I-14, which carried two aircraft while submerged; and the I-201, one of the fastest attack subs of WWII.
The submarines are widely believed to have been intentionally sunk by the U.S. Navy at the end of the war to keep the technology from the Soviet Union.
The announcement of the discovery was made by the National Oceanic and Atmospheric Administration’s Hawaiʻi Undersea Research Laboratory at Mānoa and by National Geographic Channel, which documented and partly funded the search mission for the upcoming special Hunt for the Samurai Subs.
Hunt for the Samurai Subs premieres Nov. 17, 4 p.m. HST. It replays at 7 p.m. the same day and several times after that, check local listings.
