USAF clears aerial refuelling upgrade for A-10 Warthog after rapid test campaign
April 9, 2026
The United States Air Force has successfully tested and cleared for operational use a new aerial refuelling capability for the A-10 Thunderbolt II ‘Warthog’. It’s the first time the aircraft has refuelled using a probe-and-drogue system.
In trials conducted on 2 April, an A-10 made contact with a drogue basket deployed from a Lockheed HC-130, enabled by a newly developed Probe Refuelling Adapter (PRA).
The modification allows the Warthog, traditionally limited to boom refuelling from Boeing KC-135 Stratotanker aircraft, to access a much wider pool of tanker support.
The capability has already had initial clearance from the USAF’s aerial refuelling certification authority for operational use, having been developed in response to an ‘urgent combatant command requirement’.
Rapid rollout of A-10 Warthog refuelling upgrade in weeks
Converse to many aerospace upgrade programmes, the A-10 refuelling solution was delivered at record speed.
Led by the Air National Guard Air Force Reserve Command Test Center, the programme involved multiple agencies, including the A-10 System Program Office, industry partners, and rapid contracting mechanisms through ARCWERX.
Rather than following the traditional, years-long acquisition cycle, the PRA was:
- Designed and manufactured by an industry partner
- Integrated with oversight from the programme office
- Supported by rapid contracting and on-base fabrication
- Flight tested with operational tanker crews
All within a compressed timeline measured in weeks.
Crucially, the adapter is not a permanent modification. It can be installed or removed by flight line personnel in a matter of hours, allowing units to switch between boom and probe refuelling depending on mission requirements.
This modular approach reflects a broader shift within the USAF toward field-configurable, rapidly deployable upgrades, particularly in response to real-world operational gaps.
With the retirement of the McDonnell Douglas KC-10 Extender and delays in full certification of the Boeing KC-46 Pegasus, US forces have reduced tanker flexibility. This leaves aircraft like the A-10 dependent on a shrinking number of compatible platforms.
The A-10 Warthog is proving its worth in conflict operations
The timing of this upgrade is no coincidence. The A-10 has been heavily engaged in recent operations linked to the Iran conflict, reinforcing its continued relevance despite long-standing plans to retire the fleet.
In recent weeks, the Warthog has been observed:
- Providing close air support during the rescue of a downed Boeing F-15E Strike Eagle crew
- Conducting armed overwatch and strike missions against Iranian fast attack craft in the Strait of Hormuz
- Carrying out repeated strafing runs targeting IRGC-linked positions and infrastructure
These missions play directly to the A-10’s strengths, persistence, survivability, and precision firepower in contested, low-altitude environments.
The aircraft’s ability to loiter for extended periods and operate at lower speeds also makes it a natural fit for refuelling from C-130-based tankers.
Those mission sets, long-endurance, low-altitude, and often operating close to the battlespace, are exactly the scenarios where expanded refuelling options become operationally decisive.
Not all A-10 Warthogs will retire at the end of 2026
While the A-10 is demonstrating its unique value to the Air Force in theatre, debate continues regarding just how long the Hog will stay in service.
The US Air Force targeted a complete retirement of the fleet by the end of 2026, saying that close-in gunfights are no longer an operational priority. However, Congress has blocked that plan.
The National Defense Appropriations Act (NDAA), passed in December 2025, orders the Pentagon to maintain a fleet of at least 103 Warthogs for the next two years, with final phase-out expected in 2029.
For an aircraft that hails from the 1970s, the venerable Warthog continues to demonstrate why an air force without close air support is an air force in danger. With a new aerial refuelling option now available, the A-10 just became even more useful.
