This video details the 1968 disappearance of the Soviet ballistic missile submarine K-129 in the freezing North Pacific and the unprecedented, highly classified CIA salvage mission, Project Azorian, launched to secretly recover it. Disguised as a billionaire's deep-sea mining venture, the US government constructed the Hughes Glomar Explorer, a colossal maritime vessel equipped with a cavernous internal "moon pool" and a giant mechanical claw named Clementine. Operating under the watchful eyes of Soviet spy ships, the American crew attempted to hoist the mangled, waterlogged steel hull from a crushing depth of 16,400 feet, only for the claw to fracture and drop the primary nuclear payload back into the abyss. Despite this catastrophic structural failure, the mission successfully recovered the submarine's forward bow, yielding invaluable nuclear torpedoes, Soviet naval intelligence, and the remains of six submariners who were given a solemn burial at sea.
