Meet the dive-for-glory torpedo devils of the USS Thunderfish.
World War II rages across the Pacific and Lt. Cmdr. Duke E. Gifford is in the thick of it. He evacuates children from enemy-held islands. Oversees the development of torpedoes at Pearl Harbor. And prowls the depths in the submarine Thunderfish for a chance to aim his improved "tin fish"-torpedoes-at the enemy.
John Wayne plays Gifford in Operation Pacific. "I'm no theory man. I'm a line officer," Gifford barks. He backs it up with lots of bite in several feverish sea battles. He's also a man with a loving wife at home (fellow Academy Award winner Patricia Neal). Vice Admiral Charles Lockwood, World War II commander of all U.S. Pacific submarines, was technical advisor for this adventure packing real you-are-there thrills!
