Second World War mega-submarine of Imperial Japanese Army had been
successfully mapped and filmed, a year and half after it was first
discovered off the coast of Hawaii.
Decades ahead of its time, the I-400 submarine was among the largest and technologically most advanced submarines of its era. The aircraft hangar of the submarine was large enough to facilitate the launch of at least three float-plane bombers.
