When a pilot goes down behind enemy lines, the clock starts immediately. Helicopters move in to pull the crew out, but they cannot survive without a fixed-wing aircraft overhead, suppressing enemy fire and clearing the path. For decades, that job belonged to the A-10 Thunderbolt II, flying what the military calls “Sandy” escort sorties during combat search and rescue, or CSAR, missions. Now, as the Air Force accelerates the A-10’s retirement, a basic question hangs over the entire rescue enterprise: who protects the rescuers next?
The A-10’s Sandy role and why it matters
The Sandy mission is not glamorous, but it is brutally specific. An escort aircraft must fly low and slow over hostile territory, absorb ground fire if necessary, and loiter long enough to keep threats suppressed while helicopters complete an extraction. The A-10 was built for exactly this kind of punishment. Its titanium cockpit armor, redundant flight systems, 30mm cannon, and ability to carry a heavy weapons load while burning relatively little fuel made it the default choice for Sandy sorties since the mission was formalized after Vietnam.
The role is not interchangeable with general close air support. Sandy sorties require the pilot to coordinate directly with rescue helicopters, often in radio-degraded environments, while making repeated low passes over a threat zone. Speed is a liability in this context. The aircraft needs to match the helicopter’s pace, stay in the area for extended periods, and deliver precise fire without endangering the downed crew member on the ground.
What federal audits found
The Government Accountability Office flagged the Sandy gap years ago. A 2016 report cataloged as GAO-16-816 found that the Air Force had not produced adequate data to justify retiring the A-10 without a defined replacement for its unique missions, including CSAR escort. The GAO concluded that the service was moving toward divestment without fully quantified alternatives for the capabilities the aircraft provided.
A follow-up GAO blog post published in March 2017 restated those findings in plain language, specifically calling out unresolved successor planning for the Sandy and CSAR role as a persistent gap. The core conclusion did not change: the Air Force was retiring an aircraft without demonstrating that another platform or combination of platforms could do the same job.
Those findings are now nearly a decade old. No publicly available GAO follow-up has confirmed whether the Air Force has since completed the internal analysis the watchdog demanded. That silence is itself significant. If the gap had been formally closed, the service would have strong institutional incentive to say so.
Congress keeps pressing
On Capitol Hill, the CSAR enterprise has remained a live concern through the 118th Congress. During a Senate hearing on Department of Defense appropriations for fiscal year 2025 (S.Hrg. 118-570), lawmakers questioned witnesses about the CSAR fleet’s reliance on specific airframes, including the HH-60W Jolly Green II helicopter and the HC-130J Combat King II tanker. Senators pushed on whether current and planned fleets could sustain operations in more heavily defended environments, the kind of contested airspace where a Sandy escort is not optional but essential.
A separate authorization hearing for fiscal year 2024 (S.Hrg. 118-625) addressed fleet size and modernization funding for CSAR assets, including the transition from the older HH-60G Pave Hawk to the HH-60W. Lawmakers treated the health of the rescue fleet as unsettled, probing the pace of helicopter retirements and deliveries. Both hearings underscored that the rotary-wing and tanker components of the rescue architecture are under active scrutiny, even as the fixed-wing escort piece remains comparatively undefined.
Congress has also shaped the retirement timeline directly. The fiscal year 2023 National Defense Authorization Act authorized the Air Force to begin divesting A-10s, and subsequent legislation expanded that authority. By early 2026, multiple A-10 squadrons are in various stages of drawdown, with the fleet shrinking faster than at any point in the aircraft’s history.
The successor debate
If not the A-10, then what? The most commonly discussed candidates are the F-16 Fighting Falcon and the F-35 Lightning II, but neither is a clean fit.
The F-16 has historical ties to the Sandy mission. Some units have trained on CSAR escort, and the aircraft can carry a substantial weapons load. But the F-16 burns fuel faster than the A-10, loiters for less time, and lacks the same level of survivability against ground fire. It is a capable multi-role fighter, not a purpose-built close support platform.
The F-35 presents a different set of trade-offs. Its stealth and sensor suite offer advantages in detecting and avoiding threats, but its cost per flight hour is significantly higher than the A-10’s, and its design priorities favor speed and altitude over the low, slow work that defines Sandy sorties. Defense analysts have questioned whether committing an F-35 to a prolonged, low-altitude escort mission represents a sound use of a limited and expensive asset. No official Air Force doctrine document or public decision memo has designated the F-35 as the A-10’s Sandy successor.
Unmanned systems represent another possibility. Armed drones could theoretically provide persistent overhead coverage at lower cost and without risking an additional crew. But as of spring 2026, no remotely piloted aircraft has been publicly tested or certified for the Sandy mission, which demands real-time coordination with helicopter crews in dynamic, communications-challenged environments. The technology may get there eventually, but it is not there now.
The helicopter side of the equation
While the fixed-wing escort question remains open, the rotary-wing transition is further along. The HH-60W Jolly Green II, built by Sikorsky, is the Air Force’s replacement for the aging HH-60G Pave Hawk. The new helicopter offers greater range, improved defensive systems, and better fuel capacity. Several combat rescue squadrons have received the aircraft, and the transition has been a central topic in congressional oversight.
But a more capable helicopter does not eliminate the need for a fixed-wing escort. The HH-60W is still a helicopter. It is still vulnerable to ground fire, surface-to-air missiles, and enemy aircraft. In a contested environment against a near-peer adversary, sending a rescue helicopter without robust overhead suppression is a scenario that CSAR planners have historically considered unacceptable.
The HC-130J Combat King II, which provides aerial refueling and command-and-control support for rescue missions, rounds out the CSAR triad. But like the helicopter, it depends on the threat environment being managed by other assets. The tanker extends the mission’s reach; it does not replace the firepower that keeps the landing zone survivable.
Funding and the gap window
Money is the other unresolved variable. Senate hearings confirm that CSAR modernization funding was discussed during the appropriations cycle, but the publicly available hearing text does not fully detail whether allocated dollars match stated requirements. Lawmakers expressed concern, which suggests the budget may not fully cover the transition, but the precise scale of any shortfall is not confirmed in the primary record.
The more pressing fiscal question may be timing. If A-10 squadrons stand down before a successor platform is identified, tested, and funded for the Sandy role, the Air Force faces a window in which CSAR missions would proceed without the fixed-wing escort capability that has been standard doctrine for decades. How wide that window is depends on decisions that have not been made public. The service has not released a detailed timeline mapping A-10 divestment milestones against Sandy-role transition milestones, at least not in any document available outside classified channels.
What the Air Force has not said publicly
The most telling feature of this story may be what is missing from the public record. The Air Force has not published a Sandy-role transition plan. It has not named a successor airframe for CSAR escort. It has not released an updated analysis responding to the GAO’s 2016 findings about insufficient divestment data. And it has not provided Congress with a public document that maps the path from the A-10’s retirement to a fully operational replacement capability for the rescue-escort mission.
That does not necessarily mean the work has not been done internally. The Air Force may have classified assessments, operational plans, or acquisition strategies that address the gap. But from the perspective of congressional oversight, federal auditing, and public accountability, the question remains formally unanswered. The GAO asked for better data. Congress asked for assurances. As of spring 2026, neither request has produced a visible, public resolution.
For the combat rescue crews who train to pull downed pilots out of hostile territory, the stakes are not abstract. The Sandy escort is the difference between a survivable extraction and a suicide mission. Until the Air Force puts a name, a timeline, and a budget line next to the A-10’s replacement in that role, the gap is not just a policy debate. It is a risk carried by the people who fly into the worst places to bring someone home.
