Lost Ships of WW2

The crew of a research vessel use advanced underwater cameras to locate the remains of the most famous sunken vessels of the Second World War. Just weeks before the war ended, the USS Indianapolis violently sank, and 900 sailors were stranded at sea with no rescue in sight. For five days, they fought off exposure and shark attacks in the worst disaster at sea in US naval history.

Undersea explorers aboard the research vessel Petrel detect a wreck off the coast of the Philippines that fits the profile of an American destroyer. Could it be the wreck of the USS Ward, the ship that fired America's first shot of WW2 at Pearl Harbor?

The USS Lexington birthed naval aviation and was victorious in the first carrier-to-carrier battle during the Second World War. Hours later, it erupted in flames due to enemy fire. Now, after 80 years, the Petrel crew hopes to spot the wreck and the planes that went down with her.

The Petrel team searches for the aircraft carrier USS Hornet. The Doolittle Raid was launched off her deck to avenge Pearl Harbor, but the vessel was sunk just six months later.

What happened aboard the USS Juneau would inspire the film 'Saving Private Ryan.' Five brothers were lost, but not all perished when the ship went down. At least one brother was among scores of men stranded at sea for eight horrifying days.

In one night, over a thousand Allied soldiers died when four cruisers went down in flames. Now, Petrel searches the sea for them.

Rob Kraft hunts for Musashi, the biggest battleship ever built and considered to be unsinkable by the Japanese.

Research vessel Petrel picks up what they believe to be the debris trail of the USS Johnston, 8000 feet deeper underwater than the Titanic.
