The film begins with the following written foreword: "For security reasons no motion picture on this subject has previously been permitted. Now however, through the full cooperation of our armed forces, this motion picture was filmed on board submarines, surface ships and shore installations of the Navy and Army. Much of it was made at the Naval Air Missile Test Center at Point Mugu, California. To the officers and men and to all others engaged in promoting the security of our great nation this picture is respectfully dedicated."
