Missing Japanese Mega-Submarine Found
Found in 2013, this Japanese super submarine was found just off the coast of Oahu, Hawaii. It had been missing since back in 1946, but was located about 2,300 feet deep in the water. This I-400 was the most advanced submarine of its time, capable of traveling about one and a half times around the planet without refueling. Also, it could deploy three 1800 kg bombs in minutes of resurfacing. However, it was captured by the American military at the end of the war and kept at Pearl Harbor. Once the Cold War began, the Soviets demanded it according to certain WWII treaty terms, but the Americans did not want the Soviets to acquire the technology and claimed ignorance of its whereabouts.
