Thanks to the USS COD SS-224 for their excellent descriptions and graphics.

This diagram is a "general" representation of WWII submarines. Boats built at the different yards had many subtle differences but were basically the same. The major difference was the change of pressure hull thickness for the later submarines, thus increasing the maximum diving depth. Topside armament varied from boat to boat.
