This U.S. Navy Training Film is about the basic WW2 submarine structure and systems. It is a description of the pressure hulls, tanks and super-structure.

The submarine shown at the end of the film is the USS Tusk (SS-426), a Balao class submarine. She was the only ship of the United States Navy to be named for the tusk. Her keel was laid down on 23 August 1943 and she was launched on 8 July 1945. She is one of the last two operational submarines in the world built during World War 2.

The Balao-class submarines:
The Balao-class was a successful design of United States Navy submarine used during World War II, and with 120 units completed, the largest class of submarines in the United States Navy. An improvement on the earlier Gato-class, the Balao-class submarines had slight internal differences. The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames, which increased their test depth to 400 feet (120 m).
