The US Air Force Retired Its Last A-10 Warthog – Here's What Fills The Gap

The U.S. Air Force has accelerated the retirement of its A-10 Thunderbolt II (Warthog) fleet, cutting its inventory from 162 aircraft to 103 in Fiscal 2026 after receiving congressional approval. The reduction reflects a broader shift away from the Warthog, which has been withdrawn from South Korea and replaced by F-16s, as the military prioritizes high-end deterrence against China over low-level counterinsurgency operations. The A-10 remained active in 2026’s Operation Epic Fury, targeting Iraqi militias, Iranian naval vessels, and supporting a rescue mission for a downed F-15E crew. One Warthog was lost in the operation after being hit, though the pilot ejected safely. The aircraft also demonstrated versatility in anti-maritime roles, including a 2025 modification to use laser-guided 70mm APKWS II rockets for drone-hunting. The Warthog’s retirement follows decades of political and doctrinal debates, including opposition from the 1960s/70s ‘Fighter Jet Mafia,’ which favored affordable, close-quarters combat aircraft over high-end jets like the F-15. The A-10’s design limitations prevented it from evolving into a multirole platform, unlike the F-16, which became a versatile fighter despite its origins as a simple air superiority jet. The Air Force’s shift away from the A-10 coincides with the Army’s doctrinal changes to its AH-64 Apache attack helicopters, raising questions about future close air support capabilities. While the Warthog’s retirement remains debated until 2030, its niche roles—such as anti-armor and maritime strikes—are being addressed through other platforms, including upgraded F-16s and emerging technologies. The A-10’s legacy includes 716 built, with its final retirement now contingent on budget and operational needs. The aircraft’s ruggedness and effectiveness in niche missions have kept it relevant, even as the U.S. military reorients toward peer-on-peer deterrence. The transition marks a significant shift in Air Force strategy, balancing legacy assets with next-generation capabilities.
