America's Secret Eyes, The History of the CIA's U-2 and OXCART Aerial Espionage Programs (1954-1974)

Summary

At the height of the Cold War, when the Soviet Union had become an impenetrable fortress for traditional espionage and the fear of a surprise nuclear attack gripped Washington, a handful of scientists, engineers, and spies conceived a bold solution: fly so high that no one could reach them. This declassified CIA document, written in 1992 and released in 2013, tells the complete story of the U-2 and A-12 OXCART manned aerial reconnaissance programs, from their origins in President Eisenhower's office to their technological legacy decades later. It began when the brilliant designer Kelly Johnson, working from Lockheed's legendary Skunk Works, proposed an aircraft that was essentially a jet-powered glider—so light it lacked conventional landing gear—capable of flying above 70,000 feet. The Air Force rejected it, but civilian scientists Edwin Land and James Killian rescued the concept and convinced Eisenhower to fund it through the CIA, specifically so that an overflight would not be construed as an act of war. The result was Project AQUATONE: twenty aircraft delivered on time and under budget, secretly built at Area 51, equipped with revolutionary cameras and flown by covert civilian pilots. Notably, U-2 flights at extreme altitudes accounted for more than half of all UFO sightings reported between the late 1950s and 1960s.

Between 1956 and 1960, the U-2 altered the course of the Cold War. Its twenty-four deep-penetration missions over the USSR—covering 15% of Soviet territory—debunked two of the era's greatest strategic panics: the alleged "bomber gap" and "missile gap," proving that the Soviets were not amassing vast fleets of bombers or intercontinental missiles, which allowed Eisenhower to resist enormous pressure to escalate military spending. But the Soviets could track the aircraft on radar, and on May 1, 1960, the inevitable happened: Francis Gary Powers was shot down by an SA-2 missile over Sverdlovsk. His capture unraveled NASA's cover story about a "lost weather plane," humiliated the United States, torpedoed the Paris Summit with Khrushchev, and ended overflights of Soviet territory. Powers was exchanged in 1962 for Soviet spy Rudolf Abel on Berlin's famous Glienicke Bridge. The program, however, survived: it pivoted to Cuba—where in October 1962 it provided the first photographic evidence of Soviet medium-range missiles, triggering the Cuban Missile Crisis—Southeast Asia, and mainland China, where Nationalist Chinese pilots flew 104 perilous missions at the cost of five aircraft.

Concurrently, the CIA developed the U-2's successor: the A-12 OXCART, an engineering marvel capable of Mach 3.29 at 90,000 feet, built from titanium with pioneering stealth technology. Its development was a technical nightmare—titanium cracked, hydraulic fluids did not yet exist, and the budget doubled—but the result was an aircraft whose speed and altitude were never surpassed. It was operationally deployed in 1967 from Okinawa for missions over North Vietnam and North Korea, but was cancelled in 1968 due to redundancy with the Air Force's SR-71 and because spy satellites had assumed the role of monitoring the USSR. The CIA's U-2 program was transferred to the Air Force in 1974, closing two decades of Agency operations.

The legacy of these programs transcends military intelligence. They transformed the CIA from an agency centered on human spies into a technical collection powerhouse, spurred the creation of the National Photographic Interpretation Center, and drove advances in aerodynamics, materials science, cameras, pressure suits—precursors to those used in the space program—and stealth techniques that would define military aviation for generations. It is also a deeply human story: pilots who mistook cyanide pills for lemon drops, scientists who defied military bureaucracy, and a president who personally authorized every mission knowing that a single mistake could trigger a world war.
