Dive to Disaster

Several miles off the coast of Hawaii, a routine Navy mission becomes a nightmare when a submarine's controls short circuits and the nuclear reactor starts to overload. Black Vulcan and Aquaman try to help, but are attacked by nuclear mutated sea creatures. Black Vulcan actually gets eaten by a mutated whale in which Aquaman must come to his rescue. When the two heroes get free, they make it aboard the submarine whose communication transmitter went dead. Now their only chance is to launch Aquaman out of a torpedo tube to clear the beach while Bluck Vulcan uses his electrical powers.
