The U.S. Air Force is once again exploring options for a new aircraft to replace the legendary A-10 Thunderbolt II, commonly known as the “Warthog.” The A-10, first introduced in the 1970s, has been a cornerstone of close air support (CAS) operations for decades. Its heavy armor, powerful GAU-8 Avenger cannon, and ability to loiter over battlefields have made it a favorite among troops on the ground. However, after more than 40 years of service, the Air Force believes it’s time to consider a modern replacement that can meet the challenges of future warfare.
The push to replace the A-10 is not new. For years, Air Force officials have argued that the aircraft, while highly effective in low-intensity conflicts, is increasingly vulnerable in modern combat environments dominated by advanced air defenses and long-range weapons. The A-10 was designed during the Cold War to destroy Soviet tanks and provide close support in contested ground battles, but in an era of stealth aircraft and drone warfare, its slow speed and limited survivability could be liabilities.
In recent statements, Air Force leaders have emphasized the need for a platform that can deliver close air support while integrating seamlessly with next-generation technologies. This includes improved sensors, networked data systems, precision-guided weapons, and the ability to operate alongside drones and unmanned systems. The goal is to create an aircraft that can provide the same—or greater—level of support to ground forces while surviving in more dangerous airspace.
Several potential paths are being discussed. One is the Next Generation Air Dominance (NGAD) program, a broad initiative that aims to produce a family of systems for future air combat, including manned and unmanned aircraft. While NGAD primarily focuses on air superiority, it could also produce variants capable of performing close air support missions. Another idea is developing a light attack aircraft or a multi-role jet optimized for CAS, which could be cheaper to operate than the A-10 and adaptable for different missions.
Critics, however, warn that replacing the A-10 may not be so simple. Many soldiers and military analysts argue that no other aircraft matches the Warthog’s ability to fly low, absorb damage, and deliver precise firepower. The A-10’s titanium armor and large cannon make it uniquely effective in protecting troops under fire. Attempts to replace it with faster jets, such as the F-35, have met resistance due to concerns that those planes are too expensive and not designed for low-altitude support.
Despite these challenges, the Air Force continues to move forward. Aging A-10s are becoming harder to maintain, and their airframes are approaching the limits of their lifespan. The service is studying a range of alternatives, including using a mix of manned and unmanned systems to replicate the Warthog’s mission.
Ultimately, any replacement will have to balance survivability, cost, and effectiveness. Whether the answer is a new purpose-built aircraft or a combination of existing technologies, one thing is certain—the legacy of the A-10 has set a high standard for any future close air support platform.
