On July 31, 2025, the U.S. Air Force celebrated the 70th anniversary of the famed U-2 Dragon Lady reconnaissance aircraft—and not by eating cake, but by setting a new endurance record for the class of aircraft by setting a U-2 on its first long-duration flight in 11 years.

Lockheed Martin's U-2 reconnaissance aircraft was born during the darkest days of the Cold War and was designed to unravel one of the greatest mysteries of the 1950s: What really happened behind the Iron Curtain between the West and the Soviet bloc?
This was no mere curiosity. The Soviet Union shocked the world not only because it refused to withdraw its troops from the territories it occupied during World War II, but also because it developed the atomic bomb years earlier than anyone expected, and because it carried out an aggressive program of infiltration and subversion against the West.

The Soviet leadership's boastful boasts about its military strength and technological advances, including claims that its bombers and missiles far outnumbered NATO's and that the West was simply unable to close the gap, did nothing to solve the above problems.
Nowadays, it is relatively easy to learn the truth. All major powers maintain fleets of advanced orbiting spy satellites, and images from privately owned satellites are publicly available. In recent years, it has become quite common for even amateurs to learn about what is happening in some remote corner of the world simply by pulling up images from a dozen online sources.
But in the 1950s, things were not so simple. To clarify the situation, President Eisenhower authorized the development of a new long-range, high-altitude reconnaissance aircraft that could carry cameras and fly over Soviet territory.

The end result was the U-2 "Dragon Lady" reconnaissance aircraft. Unlike other reconnaissance aircraft that were essentially converted bombers, the U-2 was lightweight, like a gauze rather than aluminum fuselage. It's more like a jet glider than an airplane, with a 105-foot (32-meter) long narrow wing that resembles a soaring bird. It is powered by a General Electric F118-101 turbofan engine that produces 17,000 pounds of thrust. Once airborne, with 2,950 gallons (11,166 liters) of fuel, the U-2 has a range of more than 6,000 nautical miles (7,000 miles, 11,280 kilometers) and a cruising speed of 412 knots (470 mph, 760 km/h).
It can also fly at the edge of space at over 70,000 feet (21,000 meters) — so high that pilots must wear pressure suits to clearly see the curvature of the Earth.
Since first taking to the skies in 1955, the aircraft has had an extraordinary career - often at the center of international crises. In 1960, the supposedly secret planes made front pages around the world when one was shot down by the Soviets and its pilot, Gary Powers, went on trial in Moscow on espionage charges. The U-2 reconnaissance aircraft made headlines again when, during a reconnaissance flight over Cuba, it discovered secret missile facilities being built by the Soviet Union within striking distance of the U.S. mainland, triggering the Cuban Missile Crisis and nearly triggering World War III.

On the positive side, the U-2 reconnaissance plane also showed that the Soviets had been playing a brilliant game of bluff, convincing the world that a handful of bombers and unstable missiles amounted to a vast nuclear arsenal.
Entering the 21st century, the U-2 reconnaissance aircraft is about to be retired, but it still has some unique skills of high-altitude flying. In July this year, a training U-2 reconnaissance aircraft named TU-2S successfully took off with two crew members from Beale Air Force Base in California, setting a flight record.
Piloted by pilot Corey "ULTRALORD" Bartholomew and Lt. Col. "JETHRO" (the latter's official name is not released by the Air Force for safety reasons), the aircraft completed the longest flight in the aircraft type's history. The two spent 14 hours flying across the continental United States, covering a distance of more than 6,000 nautical miles (6,905 miles, 11,112 kilometers). There are reports that the U-2 reconnaissance aircraft also set a new flight altitude record, but this news has not been confirmed.

This can be described as a double record, not only challenging the limits of the U-2 aircraft, but also challenging the physiological limits of the pilot. They must complete the entire flight wearing pressure suits in a small cockpit. And they don’t have toilets, so you have to eat traditional high-protein steak and eggs before the flight.
According to the Air Force, the flight was more than just a test of endurance. It also required extensive logistics, including selecting an emergency landing strip, coordinating flight routes, and dealing with issues such as wind, temperature, altitude, and how to avoid crossing the border into the wrong airspace.
"It's fitting that this flight was historic and planned and flown by the aircrew of the 1st Reconnaissance Squadron, America's longest-serving flying force," Mattson said. "The nature of warfare is changing, but our absolute sense of responsibility for our mission to create an aircrew ready to exploit and control the electromagnetic spectrum and achieve victory will never change. We will continue to hone our warfighting capabilities and demonstrate Bill's capabilities as a power projection platform to rapidly respond to adversary operations around the world."
