Production
As it has many fully restored and working parts, the World War II museum ship Gato-class submarine USS Cod (SS-224) moored in Cleveland, Ohio was used for interior and exterior scenes to depict the USS Tang, GS U-99 (1940) and GS U-100 (1940).

The film crew travelled to Laboe, Germany to film in U-995, a Type VIIC/41 U-boat which is now used as a museum. HMCS Sackville, a small, surface vessel used as a museum in Halifax, Nova Scotia, was also used.

Much of the footage inside the submarines was filmed using hand-held cameras. Because space was so tight there was often no room for the director.
