| Drama, War
Fictional account of the role played by a somewhat impetuous US Naval commander in developing the first means of launching missiles from submarines.
The guided missiles are U.S. Navy's KGW-1 missiles, later redesignated LTV-N-2, developed from V-1 Buzz Bombs created by the Germans in WWII. They may have been used in the manner shown in the movie for Operation Downfall, the invasion of Japan to end WWII.
After finally abandoning his canes and braces, Cmdr. Talbot, on the first Test Mission, has toured the submarine and tells the Admiral "it's good to walk through the ship again, Sir". A submariner would not have referred to a submarine as a "ship", rather, he would have called her "the boat".
