....just for those that might have missed it. This Japanese WW2 sub was the biggest thing to be produced during WW2...and was not eclipsed until the U.S. started building ballistic missile boats in the 1960's. She stood at over three or four stories tall and was close to 400ft in length. Follows is a weblink with some good info...
