In the 1970s, a gigantic American ship sailed slowly through the Pacific while several Soviet ships they watched him a few meters away, taking photos and listening to every conversation. On deck, the sailors talked loudly about rocks on the seabed and collected samples so that everything seemed routine, without anyone suspecting that, right under their feet, one of the most unusual operations of the entire Cold War.
An impossible robbery. At the end of the 60s, in the middle of the Cold War, the United States secretly located the Soviet submarine K-129 sunk to more than 5,000 meters deep in the Pacific, a distance that made any recovery attempt practically unfeasible.
Even so, the strategic value it was hugesince the submersible carried nuclear missiles, codes and key technology that could tip the balance at a time of nuclear parity between superpowers. With that goal in mind, the CIA launched the Azorian Projectan operation so ambitious that for years only a small circle within the Government knew of its existence.
Context. In reality, the mission, which lasted more or less six years, had begun in 1968, when the K-129 loaded with ballistic missiles disappeared without explanation somewhere in the Pacific Ocean.
The situation was not entirely strange if we think that, at that time after the Cuban Missile Crisisboth American and Soviet submarines patrolled the high seas with nuclear weapons on board, prepared for possible war.

The sinking. There are reports indicating that it was due to a mechanical failure, such as the missile’s engine accidentally starting, while the Soviets suspected for a time that the Americans had acted in bad faith.
Be that as it may, and after two months, the Soviet Union abandoned the search for the K-129 and the nuclear weapons it carried, but the United States, which had recently used Air Force technology to locate two of its own submarines sunken, located the submarine 2,400 kilometers northwest of Hawaii and 5,030 meters deep. According to the declassified history of the project by the CIA decades later, “no country in the world had managed to recover an object of this size and weight from such depth.”

The great theater of lies. Once Washington found its location and in order to hide the true purpose, one of the more elaborate covers of history: an alleged underwater mining mission led by the eccentric millionaire Howard Hugheswhose reputation made any extravagant project credible.
As? The enormous was built Hughes Glomar Explorerpresented to the world as a ship capable of extract manganese nodules from the seabed, while in reality it hid inside a secret system designed to capture the submarine. The operation was so convincing that even influenced markets and universitiesfeeding for years the illusion of a new mining industry that was never actually the objective.

Details of the construction plan of the Glomar Explorer (reproduction), from 1971. In the lower central part of the ship, you can see the plans of the so-called “lunar pool”, into which the claw could introduce the submarine
The giant claw. The heart of the mission was, possibly, the most exciting part of an already incredible story. It was a device hidden under the boat: a gigantic mechanical “claw” capable of descending kilometers to the ocean floor, hugging the hull of the submarine and raising it through a complex system of pipes and cables.
The entire process had to be executed out of sight, using an internal opening in the ship (the called “moon pool”) that allowed working completely hidden, even under the constant surveillance of suspicious Soviet ships, but they couldn’t prove anything. There is no doubt, the operation required extreme precision, withstanding colossal stresses and maintaining the ship’s position in the open sea for days, something that in itself already represented an unprecedented technological challenge.


Everything (almost) ready. In the summer of 1974, after years of preparation, the CIA managed to reach the submarine and hooked it with the claw, at which point he began to slowly raise it towards the surface, in an operation that lasted days and kept the entire crew tense.
However, halfway through the ascent, the structure gave way and much of K-129 fell back to the ocean floor, leaving only a recovered section. Even so, they managed to rescue remains of the helmet and bodies of several Soviet sailors, who were buried with honors at sea, while the real loot (the missiles and secret codes) was shrouded in uncertainty and absolute secrecy by the United States, since many of the details remain classified today.
“We neither confirm nor deny.” The biggest twist in history came when the operation came out in 1975 after leaks and thefts of documents linked to the business cover, forcing the US Government to face a most delicate diplomatic situation.
However, instead of admitting or denying the theft of a Soviet nuclear submarine more than 5,000 meters deep, Washington adopted a response that would go down in history: “We neither confirm nor deny”a formula designed to avoid direct tensions with Moscow and which has since become a standard in intelligence matters. That calculated silence It encapsulates the essence of the entire operation: a gigantic mission, almost impossible on paper, visible to everyone in appearance, but whose true purpose and results remain, to a large extent, hidden from the general public.
The legacy. Although he Azorian Project did not recover the entire submarine, it left a deep mark on history of espionage and engineeringamong other things because it demonstrated that it was possible to operate at extreme depths and execute missions of a unprecedented complexity.
Of course, it also demonstrated the extent to which the Cold War promoted radical technical solutions and operations that bordered on the improbable, in a race for gain strategic advantage at any price between both sides. Decades later, it remains one of the most audacious episodes ever conceived: the real attempt to steal, silently and from the bottom of the ocean, the nuclear secrets of the Soviets with a claw closer to fantasy literature.
