The United States Air Force has been trying to kill the U-2 Dragon Lady for the better part of three decades. The U-2 keeps winning. On June 10, 2026, the House Appropriations Defense Subcommittee released a draft FY2027 spending bill that bars the Air Force from retiring more than two U-2s and adds $81 million to fully restore four aircraft through programmed depot maintenance. This comes despite the Air Force’s budget request to retire the entire 23-ship fleet in FY2027, zeroing out all U-2 operations and maintenance funding. It is the latest chapter in what might be the most stubborn survival story in American military aviation.

A History of Not Dying

The timeline of U-2 retirement attempts reads like a comedy of repeated failure — if you are the Air Force, and a triumph of Congressional stubbornness if you are anyone else. The service has tried to retire the Dragon Lady in some form since the 1990s, arguing each time that satellites, drones, or some other platform could replicate its capabilities at lower cost and lower risk. Each time, Congress has disagreed. The FY2021 NDAA blocked retirement but included a waiver allowing the Pentagon to divest if the Secretary of Defense could certify that the resulting capability gap would be filled cost-effectively. On October 30, 2023, Secretary Lloyd Austin signed that waiver. The Air Force thought it was finally free. It was not. In June 2024, the House Appropriations draft for FY2025 explicitly blocked any U-2 divestment or even preparation to divest. The FY2026 spending bill, passed in January 2026, permitted the retirement of no more than eight aircraft and provided $55 million for depot maintenance. The first U-2 — tail number 80-1085 — was sent to the boneyard at Davis-Monthan AFB in December 2025. Now, with FY2027, the screws have tightened further: only two may go, and four must be restored.

Why It Will Not Die

The U-2 operates above 70,000 feet — higher than any other operational non-orbital platform on Earth. At that altitude, its sensors can peer deep into denied territory using slant angles from international airspace, without ever crossing a border. Its payload includes the ASARS-2 synthetic aperture radar for all-weather ground imaging, the SYERS electro-optical and infrared system for multi-spectral real-time imagery, comprehensive SIGINT suites covering both communications and electronic intelligence, and communications relay packages that have made it an invaluable data-link translator between fourth and fifth-generation fighters. That last capability is not trivial. In joint exercises, the U-2 has acted as a bridge between the F-22’s proprietary IFDL data link and the F-35’s MADL system and the broader Link-16 network — essentially serving as a flying Rosetta Stone for platforms that cannot talk to each other directly. In 2023, the U-2 demonstrated its continued relevance by flying above the Chinese surveillance balloon that crossed the United States, collecting intelligence from directly overhead while the nation debated what to do about it. On August 1, 2025, a Dragon Lady flew a record 14-hour mission covering 6,000 nautical miles to mark the aircraft’s 70th anniversary. The Air Force’s argument for retirement is not without merit. The fleet averages more than 40 years old. The last airframe was delivered in 1989. Mission capable rates have been declining — from 76 percent to 61.9 percent for single-seat aircraft, and from 81 percent to 59.2 percent for the two-seat TU-2S trainer, both between FY2023 and FY2024. Diminishing manufacturing capacity and material shortages make sustainment increasingly expensive. The Pentagon’s FY2027 force structure report stated bluntly: “The Air Force will retire the entire 23-ship U-2 fleet, as the platform is no longer viable for future high-end conflicts. Continued operation presents significant safety, logistical, and financial risks that outweigh the platform’s remaining utility in contested environments.” But Congress looks at the same situation and sees an irreplaceable asset being thrown away before its replacement is ready.

What Comes Next — Eventually

The planned successors are a mix of space-based surveillance satellite constellations, targeted for early fielding by 2028 under the U.S. Space Force, and a classified stealthy high-altitude drone widely referred to as the RQ-180. The drone — a 130-foot wingspan flying-wing design built by Northrop Grumman — was spotted operating from a base in Greece in April 2026, confirming what had long been rumoured about its advanced state of development. The B-21 Raider is also expected to contribute ISR capability. The RQ-4 Global Hawk, which the Air Force had once positioned as the U-2’s replacement, is itself now slated for retirement by the end of FY2027. The irony is thick: the drone that was supposed to replace the spy plane is being retired first.

What $81 Million Buys

Programmed depot maintenance for a U-2 is not a simple oil change. It is a full tear-down: paint stripped, aircraft completely dismantled, more than 1,800 parts removed, 40,000 rivets inspected, the structure checked for cracks and corrosion, then reassembled and flight-tested. Upgrades — including elements of the ongoing Block 20.1 modernisation — are often worked into PDM cycles. Previous depot maintenance was conducted at Lockheed’s Skunk Works Site 2 in Palmdale; recent work has shifted to Beale AFB. Restoring four aircraft through this process is a signal that Congress does not merely want the U-2 to limp along. It wants the fleet healthy. The Dragon Lady first flew on August 1, 1955, from Area 51 under the CIA’s Project Aquatone, designed by Clarence “Kelly” Johnson at Lockheed’s Skunk Works. Francis Gary Powers was shot down over the Soviet Union on May 1, 1960. The aircraft survived that political crisis, survived the satellite revolution, survived the drone revolution, and is now surviving the Air Force’s latest attempt to send it to the boneyard. Seventy-one years after its first flight, the U-2 Dragon Lady remains the aircraft the Pentagon cannot figure out how to replace — and Congress refuses to let go of until it does.
