The double hull of a submarine is different from a ship's double hull. The external hull, which actually forms the shape of submarine, is called the outer hull, casing or light hull. It defines the hydrodynamic performance of submarine, which affects the amount of power required to drive the vessel through the water.
Submarines of World War II represented a wide range of capabilities with many types of varying specifications produced by dozens of countries. The principle countries engaged in submarine warfare during the war were Germany, Italy, Japan, the United States, United Kingdom and the Soviet Union. The Italian and Soviet fleets were the largest.

The Gatos, along with nearly all of the U.S. Navy fleet-type submarines of World War II, were of partial double-hulled construction. The inner pressure-resisting hull was wrapped by an outer, hydrodynamic hull. The voids between the two hulls provided space for fuel and ballast tanks.
The two submarines of the Shark group were developed by Electric Boat and they were built to a partial double hull design with single hull ends, a refinement of an earlier hull type used on the Dolphin. Six submarines of the Perch group were authorized for construction in Fiscal Year 1935. The Navy thought the Electric Boat design to be the ...
Seawolf was the same basic "double hull" twin-screw submarine design as her predecessor USS Nautilus (SSN-571), but her propulsion system was more technologically advanced. The Submarine Intermediate Reactor (SIR) nuclear plant was designed by General Electric 's Knolls Atomic Power Laboratory and prototyped in West Milton, New York .
The Kaichū Type (海中型, Navy Medium Type) VI submarines were double-hulled, medium-sized submarines. They were derived from the preceding Kaichū V Type and had improved performance. Constructed between 1933 and 1937, they served as prototypes for the major production Kaichu VII type constructed during World War II.
This is a list of submarines of World War II, which began with the German invasion of Poland on 1 September 1939 and ended with the surrender of Japan on 2 September 1945. Germany used submarines to devastating effect in the Battle of the Atlantic , where it attempted to cut Britain's supply routes by sinking more merchant ships than Britain ...
