Japanese Supersub

Season 9, Episode 4 of 4

Spring, 1946. Ten months after the end of World War II, an explosion rocked the Pacific off the coast of Hawaii. America had just destroyed one of Japan's most advanced weapons systems. But this was no belated attack against the defeated Japanese. Rather, it was an attempt to keep an advanced, top-secret submarine out of the hands of the Russians. What was this sub and where had it come from? Secrets of the Dead: Japanese SuperSub investigates, revealing the startling story of Japan's successful creation of a technological masterpiece-an aircraft carrier submarine that could blow up the Panama Canal, reach the U.S. main land undetected, and unleash panic-inducing air attacks on American civilians. How close did Japan's secret sub come to attacking America? And how did America's own top-secret super-weapon put an end to the Japanese threat?
