National Museum of the Pacific War in Fredericksburg, Texas, houses the Japanese midget sub that ran aground during the attack on Pearl Harbor in 1941. I was surprised to learn that this "midget" is nearly 80 feet long and is powered by a 600 hp electric motor. The contra-rotating props are almost 4.5 feet in diameter.Sorry I didn't get a full-length shot. The museum was about to close and they were running us out a little early. -Jim
