The Japanese I-400 class submarines of World War II had side-by-side
pressure hulls.  Counting the aircraft hanger as a third pressure
hull, they came very close to the supposed Typhoon configuration.
[I-400 class were built for carrying and launching floatplanes.  They
were  the biggest submarines in World War II.]
