The submarine USS Thunderfish successfully completes a secret mission to rescue a group of orphans on a remote Pacific island. On the way back to Honolulu they encounter a Japanese aircraft carrier but the torpedoes they fire explode about halfway to the target, a recurring problem that has plagued the submarine fleet for some time. The Thunderfish's XO, Duke Gifford runs into his ex-wife and Navy nurse Mary Stuart at the hospital. There's still a spark between them but the boat is sent out on another mission before anything is resolved. When Gifford's good friend and captain, Pop Perry, is killed Gifford believe it's his fault. A inquiry clears him and after he and his men solve the problem of the misfiring torpedoes, they set out to sea. Written by garykmcd

Did You Know?


The problems with submarine torpedoes shown in the movie are accurate. A poorly designed and tested firing pin could malfunction on a good hit (that is, a torpedo striking within about 45 degrees of perpendicular to the side of the target). Poor hits (at a very sharp angle to the side of the ship) could often produce more reliable explosions. Finding the problem, while not performed by the submarine crews as shown, actually did occur in a similar manner. See more »


When the dummy torpedo warhead is being hauled up by crane and dropped on a target to test the new firing mechanisms, 3 tests are performed. All 3 tests are the exact same piece of footage. You can tell by the way the warhead bounces when it hits its target, the same 2 seamen are to either side of it in the foreground in all 3 tests, and the left seaman jerks his right arm to the left in exactly the same manner in all 3 tests.

Crazy Credits

In keeping with the submarine theme of the film: at the very start, we see a submarine periscope break the surface of the sea, then we see an officer looking into the view-port of the periscope, then we see the opening credits appear, as if being viewed through a periscope. See more »

Lightly entertaining John Wayne submarine drama

Lightly entertaining John Wayne submarine drama.

The Pacific Theatre of WW2. Lt Commander Duke Gifford (played by John Wayne) is the Executive Officer of a US Navy submarine, the USS Thunderfish. The submarine fleet, incl the Thunderfish, is suffering from malfunctioning torpedoes. Meanwhile Commander Gifford is also trying to win back his ex-wife...

A stereotypical John Wayne movie, i.e. overly gung ho and not that accurate, militarily. Some quite unrealistic battle scenes. The relationship side is mildly interesting but also overly melodramatic and complex.

Not all bad though, as long as you don't think too much. The battle scenes are quite exciting and there are some insights into submarine life.
