The Porpoises
were completed in 1935-1937 and
represented a trend away from the cruiser submarine concept towards smaller,
handier
boats. However, they still had atrocious dive times, though
they were capable
of diving deep and were quite habitable (for submarines.)
There was some
variation in detail within the class, so that some authors break it up
into
three types.
