Secrets Of The Dead: Japanese Super-Sub

Watch Japanese SuperSub on PBS. See more from Secrets of the Dead.

For the longest time there was a rumor of a Japanese designed "super sub" that was built to blow up American cities on the west Coast and even inflict enough damage to the Panama Canal as to render it useless....but these stories were discounted.  That is, until the remains of one was found in the waters off of Hawaii.  These were no ordinary subs, they were designed to act as air craft carriers in an offensive way and even were designed to carry out attacks on the East coast of the US from Washington DC to NYC...scary stuff indeed!  Since then, actual photographers of this monster have been uncovered.
