Four U-2S Spy Planes Would Be Restored In Bill That Would Save The Dragon Lady Fleet

Members of Congress are again moving to block the U.S. Air Force from retiring all of its U-2S Dragon Lady spy planes. This time, legislators also want to compel the service to “fully restore” four of the iconic aircraft through heavy depot maintenance, which would bolster the fleet’s operational capacity. The Air Force continues to argue that the high-flying Cold War-era jets are too vulnerable to support future high-end fights and should be supplanted by a mix of space-based and other capabilities. This would presumably include a classified stealthy high-altitude drone, commonly (and unofficially) referred to as the RQ-180, or an evolution thereof, which first emerged publicly just earlier this year.

Yesterday, the House Appropriations Committee released a draft defense spending bill for the 2027 Fiscal Year. It includes a provision that would prevent the Air Force from retiring more than two U-2Ss in that fiscal cycle. The Air Force currently has 23 of these aircraft in inventory, including three two-seat TU-2S trainers.

A summary of the proposed legislation also says it includes “$81 million for U-2 programmed depot maintenance to fully restore four aircraft.” The current operational status of the aircraft in question is unclear. This is included under the umbrella of $335.3 billion in total funding for operation and maintenance (O&M) accounts across the services that the draft bill would appropriate for Fiscal Year 2027.

Programmed depot maintenance for any aircraft is an intensive process that essentially involves a full tear-down and detailed inspection. Paint and other coatings are typically stripped and reapplied. Upgrades and modifications are often worked into depot maintenance cycles given the extensive work already being done.

The Air Force’s proposed budget for the 2027 Fiscal Year completely zeroes out the line for U-2 O&M, to include depot maintenance, reflecting the service’s desire to retire the fleet. An annual force structure report the Pentagon released in May concisely outlines the current argument for retiring the remaining U-2Ss.

“The Air Force will retire the entire 23-ship U-2 fleet, as the platform is no longer viable for future high-end conflicts,” the force structure report says. “Continued operation presents significant safety, logistical, and financial risks that outweigh the platform’s remaining utility in contested environments.”

“This decision allows for the strategic reallocation of fiscal resources to fund more critical, high-priority service requirements and accelerate modernization efforts in other key areas,” it adds. “Continuing to operate the U-2 fleet would require a significant investment to address systemic issues, including diminishing manufacturing capacity, material shortages, and safety risks inherent in the aging platform.”

Questions about the continued relevance of the U-2 in the face of an ever-expanding global air defense threat ecosystem are not new. Near-peer competitors like China and Russia, as well as lower-tier potential adversaries like Iran, continue to develop and field more capable air defense systems and expand their anti-access and area denial bubbles. This, in turn, has threatened to push the U-2 further and further from the areas where it would be tasked to collect.

On top of all this, the U-2s are aging and becoming more costly to operate and maintain. The U-2S models in service today were upgraded from earlier variants that began their service careers in the 1980s.

As noted, this is not the first time the Air Force has tried to retire its remaining U-2s, citing operational and sustainment-related factors. In response, Congress has repeatedly intervened in the past few years to at least block full divestment of the fleet over persistent concerns about the aerial intelligence, surveillance, and reconnaissance (ISR) capability and capacity gap that might result.

The Dragon Lady continues to offer a unique ISR platform that can fly higher than any other operational non-orbital platform, crewed or uncrewed, the U.S. military has, at least from what we know today. This, in turn, means that the aircraft can bring imaging, signals intelligence, communications payloads, and other sensors up to those altitudes, giving them particularly good fields of view. From this perch, aircraft can use a slant angle to peer deep into denied areas while still flying international airspace and further away from potential threats. The use of the U-2 to gather intelligence about a Chinese spy balloon that soared over parts of the United States and Canada in 2023, which involved flying above it, offered a particularly public demonstration of the value of the aircraft’s high-altitude capabilities.

Each Dragon Lady can also carry a wide array of different sensor systems simultaneously, as well as communications packages, further increasing its flexibility. The U-2Ss have the ability to be readily deployed to forward locations globally and conduct long-duration sorties, as well. The latter points have been especially relevant in comparison to known existing ISR satellite constellations that are constrained by their orbits and can only offer relatively short-term coverage over a specific area. We will come back to this in a moment.

It is worth noting here that the Air Force’s Dragon Lady fleet also has a long history now of providing valuable ISR support outside of traditional combat operations. Last year, the service confirmed U-2Ss were supporting the enhanced border security mission along the United States’ southern boundary with Mexico. The aircraft have been used to support counter-narcotics operations over the years, as well as humanitarian assistance and disaster relief missions. NASA also operates a pair of ER-2 aircraft, another version of the Dragon Lady, as high-flying scientific research platforms.

The Air Force has been hinting for years now at the existence of advanced aircraft in the classified realm that could help fill gaps left by the retirement of the U-2, and also be more survivable in very high-threat environments. This has now been further underscored by the emergence of the ‘RQ-180,’ or a related stealthy design, in Greece earlier this year, the likely capabilities and roles of which TWZ explored in a detailed feature in April. At the same time, we have raised still unanswered questions in the past about how many of any such drones might actually be in service and what kind of operational capacity those fleets might provide.

The U.S. military is also pushing ahead with the development and fielding of new space-based ground and air surveillance capabilities. This includes work toward the fielding of new satellite constellations that could provide game-changing persistent coverage globally, as you can read more about here. Despite steady progress, including on-orbit testing of prototypes, there are still questions about when any of these new assets in orbit will be fully operational. The U.S. Space Force recently announced it is now targeting 2028 for the “early” fielding of at least some of these new space-based surveillance capabilities.

The draft defense spending bill from the House Appropriations Committee does still have to be finalized, and then brought in line with companion legislation in the Senate. Both chambers of Congress then need to pass the bill before it can be sent to the President’s desk to be signed into law. There are many opportunities along the way for major changes to be made to the bill.

That being said, Congress has consistently blocked Air Force efforts to fully retire the U-2 in recent years. Another potential reprieve, which would also demand the service take steps to bolster the operational capacity of the remaining fleet, has now appeared on the horizon.
