On 18 August 2026 a single A-10C Thunderbolt II took off from Nellis Air Force Base, flew a training mission over the Nevada Test and Training Range, and landed. Nothing about the sortie was unusual except everything about it.

The aircraft was 82-0665, the last A-10 ever built, delivered on 20 March 1984. The pilot was Lt. Col. Ridge Flick, commander of the 66th Weapons Squadron. And it was the final training flight of the United States Air Force Weapons School’s A-10 course, ending a graduate-level instructor pipeline that had run at Nellis since 1977.

Four months earlier, in April 2026, the Air Force had announced it was extending the A-10 to 2030. Both of those things are true at the same time, and that is the actual story here.

What the 66th Weapons Squadron Actually Did

The Weapons School is not where you learn to fly the aeroplane. It is where the people who will teach everyone else learn to be authorities on it. The 66th ran a six-month course whose climax was the mission employment phase, a two-week staged battle across the Nevada Test and Training Range. Graduates go back to their units as weapons and tactics officers, advising commanders and operations officers on how the aircraft is actually employed.

For the A-10 that meant close air support, forward air control, combat search and rescue and, latterly, counter-maritime work. It is a narrow, unglamorous and extremely specific body of knowledge, and the squadron was where it lived.

The squadron itself has an odd, doubled history with the type: it flew A-10s in the Weapons School role from 1977 to 1981, was reactivated as the 66th Weapons Squadron in February 2003 to replace the school’s A-10 division, and has flown them ever since. The lineage goes back further still, to a unit that flew P-40s and P-47s in the Second World War and F-105s and F-4s on Wild Weasel training in the Vietnam era.

The Air Force’s own wording for what ended on 18 August was careful and flat.

One Correction Before We Go Further

The version of this story circulating on social media says the Air Force is still flying three A-10 squadrons through 2030. That is not quite what was decided, and the difference matters.

The April 2026 decision extended three squadrons, each holding 18 aircraft — 54 jets in total — through 2029. From 2030 the fleet drops to 36 aircraft in two squadrons: one active-duty unit at Moody Air Force Base in Georgia and one Air Force Reserve squadron at Whiteman Air Force Base in Missouri. So it is three through 2029 and two through 2030, not three through 2030.

Congress may yet move the line again. Representative Abe Hamadeh’s BRRRRT Act would require the Air Force to keep 126 A-10s flying through fiscal 2033, and the House-passed fiscal 2027 defence bill would oblige the service to retain enough training, depot and logistics capacity to support the fleet through 2030. Neither is law. The fiscal 2026 National Defense Authorization Act had originally mandated full retirement by 2029.

Everything Needed to Operate an A-10 Has Already Been Shut Down

Here is the part that does not fit on an Instagram card. The Air Force extended the A-10’s service life in April 2026. By then it had already begun dismantling the machinery that keeps A-10s flying, and it carried on afterwards.

In February 2026, Hill Air Force Base completed its final A-10 depot overhaul. The 571st Aircraft Maintenance Squadron, which had done structural repairs, wing replacements and major overhauls on the type since 1998, began preparing to deactivate. In March 2026, Davis-Monthan graduated its last class of newly qualified A-10 pilots, ending dedicated ab initio training on the aircraft. In May 2026, maintainers there completed the final TF34 engine build.

Depot in February. Extension in April. Pilot school in March. Engine line in May. Weapons School in August. The decision to keep the aeroplane arrived in the middle of the sequence that removed the ability to support it.

The remaining fleet will be sustained substantially by cannibalising airframes that have already been retired. That works, for a while. It also means every jet sent to the boneyard props up the ones still flying while shrinking the pool available for training, testing, attrition replacement and whatever the Air Force does not see coming.

Why the A-10 Got a Reprieve at All

The extension was not sentiment. It was Iran.

A-10s flew close air support during Operation Epic Fury, worked maritime targets in the Strait of Hormuz, and took part in the combat search and rescue mission that recovered two downed F-15E crew. An aircraft that the Air Force had spent a decade trying to retire turned out to be the one doing jobs nobody else was available to do.

Read that carefully. It is not a statement about the A-10 being good. It is a statement about there not being enough other aircraft yet — which is also why the Air Force fighter inventory has been sitting below the congressionally mandated minimum.

What Actually Ended on 18 August

Not the A-10. Three squadrons are still flying it, and will be for years. What ended is the production of the people who know the aircraft best.

A weapons officer is not a pilot who is good at the jet. It is the person a squadron commander turns to when the tactics question is genuinely hard, and the Air Force has now stopped making new ones for the A-10. The ones already out there keep their expertise, and then they get promoted, or they move to another airframe, or they leave. Nobody replaces them. The fleet has a fixed number of real experts left and a declining curve.

That is the thing worth noticing about all four closures together. The depot, the pilot school, the engine line and the Weapons School are not four sad milestones. They are the same decision, executed in stages, and the 2030 extension was bolted on top of it without undoing any of it.

One small note on timing, since it confuses people. The flight was on 18 August. The story only travelled in mid-September, which is why a month-old event has been showing up in feeds as breaking news.
