SUMMARY

  •  The U-2 spy plane, developed by Lockheed in secrecy, remains in service and is the only high-altitude manned ISR platform.
  •  The U-2 has proved its versatility, used for various missions beyond spying, and can operate where other aircraft can't.
  •  The Air Force is planning to retire the U-2 fleet in FY 2026, ending a 70-year legacy of service.
Lockheed's U-2 spy plane was one of the most iconic aircraft of the Cold War and played a prominent role in the Cuban Missile Crisis of 1962. Today, it is one of the oldest aircraft still in US Air Force service, having first flown in 1955 and entered service in 1956. It was designed to be hard to detect and to be a high-altitude reconnaissance aircraft. U-2s remain in service and are now the Air Force's only manned high-altitude ISR platform.

The Air Force's 70-year-old versatile spy plane

The U-2 spy plane was developed in covert conditions by Lockheed Martin's secretive "Skunk Works" in Burbank, California. It was designed with sailplane-like wings optimized for the thin atmosphere above 55,000 feet (later over 70,000 feet). They first entered service in 1956 and the last was delivered in 1989.

U-2s have been used for more than just spying on the communists. They have been used for mapping studies, atmospheric sampling, and even collecting crop and land management photographic data for the Department of Energy. U-2s have been used to enable communication between different generation fighter jets.

Satellites and drones had been planned to replace the U-2, but the U-2 persisted in being able to fly missions in an environment no other aircraft is able to operate. The U-2 can also be used as a platform to test sixth-gen platforms.

“We’re using U-2 in unique and innovative ways and as a surrogate platform, decreasing risk for our fifth-gen fighters, all we’re doing is decreasing risk and increasing the technical mature for stuff we’ll use on the F-35, F-22." Col. William Collins - senior materiel leader for ISR (reported by Air and Space Forces Magazine )

According to Lockheed Martin, the U-2 has proven flexible as a platform to demonstrate new capabilities faster and more cost-effectively for a Joint All-Domain Operations vision. Its unique and modular design enables it to demonstrate and prove new technologies in weeks, not years. Lockheed Martin states it has "demonstrated open architecture and superior size, weight, power, and cooling (SWAP-C) capacity."

In 2023, the Air Force's U-2 was one of the assets used to collect intelligence on the intruding Chinese 'spy balloon' as it floated across Canada and the US before an F-22 Raptor popped it (the only enemy air-to-air kill for the world's most advanced air superiority jet).

The two U-2s shot down

The U-2 Dragon Lady entered service in 1956 and remained secret until May 1, 1960, when the Soviets shot one down as it flew a spying reconnaissance flight over Soviet territory (it was civilian piloted).

It was a U-2 (piloted by Maj. Richard S. Hersey) that first discovered the Soviet missile sites in Cuba on October 14, 1962. Eight days later, a U-2 spy plane was shot down during the Cuban Missile Crisis by a surface-to-air missile. Things could have escalated dramatically when that U-2 was shot down over Cuba, but cooler heads prevailed.

The wreckage of these aircraft is now on display in museums in those countries. The Military Museum of the Chinese People's Revolution in Beijing also displays the wreckage of a U-2C (56-6691) shot down over China in 1965. According to CNN, five U-2s were shot down over China. However, at the time, all U-2s were the responsibility of the CIA, and the agency never officially explained what they were doing over China. They were also piloted by Taiwanese pilots and claimed to be involved in a weather research initiative.
