In the year 1968, there were four separate cases of submarines disappearing under mysterious circumstances: the American Scorpion, the Israeli Dakar, the French Minerve, and the Soviet K-129. The last of these events came under scrutiny when, six years later, a United States black project disguised as a manganese mining operation attempted to locate and salvage what was left of the Soviet submarine. This program was known as “Project Azorian,” and was primarily carried out by a single vessel known as The Glomar Explorer.
