Proposed Law Would Keep 126 A-10 Warthogs and Rebuild Support Through 2033

Keeping the A-10 Warthog available for ground troops would require the Air Force to reverse part of a retirement effort already dismantling the aircraft’s support network. Proposed legislation known as the BRRRRT Act would set a floor of 126 A-10 Thunderbolt IIs through fiscal 2033 and require the service to restore depot maintenance, pilot training and sustainment capacity that it had begun winding down.

The proposal raises the previously legislated fleet floor of 103 aircraft. It also would block additional retirements until senior Air Force, Army, Marine Corps and U.S. Special Operations Command officials certify that another capability has fully assumed the A-10 mission. That condition addresses a central concern in the retirement debate: The Air Force can distribute close-air-support duties among other aircraft, but it has not designated one direct replacement for the Warthog.

Keeping airplanes means rebuilding an entire operating system

A fleet minimum is more consequential than preserving 126 airframes on an inventory sheet. Aircraft need trained pilots, maintainers, spare parts, engineering support, depot slots, test capacity and functioning training pipelines. Once those elements have been reduced, restoring them can compete for the same skilled personnel, facilities and funding needed elsewhere.

That reversal is especially significant because the A-10 fleet is more than four decades old. Remaining aircraft require continuing structural work, including overhauls and wing replacements, to stay airworthy. Sustainment demand generally does not disappear merely because a minimum fleet size is written into law; the service must keep enough of the retained aircraft mission-capable while others move through inspections and depot work.

The Air Force argues that retiring the A-10 would release money and manpower for the F-35 fighter, B-21 bomber and planned F-47 fighter. The proposed law would narrow that planning flexibility. It would not necessarily cancel those newer programs, but it would force the service to support an older fleet while simultaneously staffing, maintaining and introducing newer aircraft.

That creates a public-resource tradeoff rather than a simple contest between an old airplane and new technology. Retaining the Warthog purchases continued close-air-support capacity and more time to validate a successor. The cost is sustained demand on maintenance organizations, training billets and modernization accounts whose capacity is not unlimited.

The A-10’s mission remains harder to replace than its airframe

The case for retention rests on a real capability combination. The A-10 carries the 30mm GAU-8 Avenger cannon and is valued for its firepower, loiter time and close-air-support record. Ground forces have long trusted a platform designed around supporting them, rather than an aircraft treating that work as one mission among several.

The opposing engineering concern is that the non-stealth A-10 was designed around a low-speed, low-altitude operating profile. Analysis in the retirement debate holds that modern surface-to-air missiles, portable air-defense weapons and networked sensors increase the risks associated with that profile. That is not an official finding that the aircraft has become unusable everywhere. Survivability depends on the threat environment, supporting forces and mission conditions, which means the A-10’s utility cannot be reduced to either “proven” or “obsolete.”

The bill’s certification requirement would shift the burden from accepting a distributed replacement concept to demonstrating that the mission has actually been assumed. The required approvals from several services reflect who depends on close air support, but they could also make retirement harder even if the Air Force believes a mixture of aircraft can provide the necessary coverage.

The proposal further calls for evaluating autonomous, semi-autonomous, artificial intelligence-enabled, and adjunct aircraft capabilities. That language broadens the replacement discussion beyond finding another manned aircraft with the A-10’s shape or weapons. A future solution could distribute sensing, endurance and support functions across multiple systems, although the proposal itself does not establish that those technologies are ready to replace the Warthog.

Retirement is already changing the support footprint

The institutional reversal would not be theoretical. On July 29, A-10Cs completed their final flights at Davis-Monthan Air Force Base, ending nearly 50 years of A-10 operations at the installation. The Air Force described aircraft divestment and the removal of flight-line infrastructure there, illustrating how retirement decisions extend beyond airplanes to the people and facilities surrounding them.

The BRRRRT Act remains a proposal, not an enacted fleet plan. If adopted, however, its most immediate effect would be measurable: The Air Force would have to sustain at least 126 Warthogs through fiscal 2033 while rebuilding the maintenance and training machinery needed to fly them. The decisive question would then move from whether the A-10 is admired to whether the United States can define, test and certify a replacement before another decade of sustainment becomes the default transition plan.
