Several subs appear in stock footage. The jet-propelled torpedo gets loaded onto a real sub that appears to have a fake conning tower, probably built over the real conning tower to make this sub visually match the sub that appears later. It's hard to read the sub's number in the torpedo-load scene, but it appears to be 334 - - USS Cabezon. Cabezon arrived in California 1953 to join the reserve fleet and might have been undergoing inactivation when the film crews set up. See more »

Narrator: From her beginnings on a Navy drawing board, through the months of secret field experiments out on the Western desert, then through the desperate search for new metals with the properties she needed, she was designed to be the nation's greatest weapon of the seas - the atom-powered submarine.

Great Classic Film in 1955 !
13 July 2004 | by (United States) – See all my reviews

Greatly enjoyed viewing this film in the 1950's and all the audiences were thrilled at seeing this sea monster tackle the Golden Gate Bridge and terrify all the people in San Francisco. This film cannot compare to the films being made in 2000, however, in 1955 it was a great B Film and is presently and always will be a great Classic. Kenneth Tobey, who was a submarine captain, "Body Shot",'93 gave an outstanding performance along with Faith Domerque,"The House of Seven Corpses",'74 who was a beautiful young actress and acted like a very strong willed woman who was hard to charm off her feet. Unfortunately, Faith had a short career due to her struggle with cancer. This is truly a great Classic Film of the 50's. Enjoy!
