WWII's Craziest Engineering: How the Navy Raised the Ghost Fleet?

Pearl Harbor was a graveyard of steel, but the US Navy performed a miracle to raise the dead. How did engineers use the "Wallin Patch" and massive cofferdams to resurrect the Ghost Fleet from toxic mud and return them to war?

In this documentary, Valor Sea explores the unprecedented Pearl Harbor Salvage Operation authorized by Admiral Chester W. Nimitz. We analyze the deadly challenges faced by divers in Mark V suits battling hydrogen sulfide gas and total darkness inside the sunken hulls. Discover the insane engineering behind "parbuckling" the overturned USS Oklahoma, the cofferdam construction for the USS California, and how the USS West Virginia rose to exact revenge at the Battle of Surigao Strait.
