VIDEO: Sunken Japanese Submarine Discovered
A sunken Japanese submarine was discovered by US researchers off the coast of Hawaii in more than 2,300 feet (700 meters) of water, as reported by the RIA Novosti.
The submarine, named Sen-Toku (I-400), was scuttled by the United States after the WWII and disappeared in 1946.
I-400 was the largest submarine ever built until the 1960s, since nuclear-powered submarines were popularized.
She was designed to surface, launch her planes, then quickly dive again before she was discovered.
She also carried torpedoes for close-range combat.
The I-400-class was designed with the range to travel anywhere in the world and return.
