The working titles of the film were Down Periscope and Submarine School. The following written foreword appears after the opening credits: "This picture was photographed almost in its entirety aboard United States Naval vessels and in Naval shore installations. For making this possible, we gratefully acknowledge the cooperation of the United States Navy, and the Department of Defense without which the picture could not have been made. The Producers would like to express their gratitude to the United States Naval Submarine School, New London, Conn., and the Submarine Forces of the United States Atlantic and Pacific Fleets."
Although a February 1943 Hollywood Reporter news item reports that Lindsley Parsons planned to produce a film on P-T boats for Monogram called Torpedo Alley, it is doubtful that that film was related to the 1952 Torpedo Alley. According to an August 1952 Daily Variety article, Allied changed the title of the film after discovering that RKO had already registered the name Down Periscope. The Variety review notes that documentary footage of submarines at sea was interspersed with studio and location shots. Most of Torpedo Alley was shot on location in San Diego, CA and New London, CT. Hollywood Reporter news items from July 1952 add Richard Garland and Navy officer Lee Graham to the cast, but their appearance in the final film has not been confirmed.
