What a Warthog Replacement Means

The A-10 Thunderbolt II, commonly called the Warthog, is a single-seat attack aircraft built to destroy tanks and provide close air support to ground troops. The U.S. Air Force has flown the same basic design since 1976, and for decades the military has studied what aircraft might eventually take its place. A replacement does not mean the Air Force is retiring all Warthogs tomorrow — it means identifying and testing a successor aircraft that can do the same job with newer technology.

The challenge is that the Warthog does one thing exceptionally well: it flies low and slow, carries a massive 30mm cannon, and can absorb battle damage that would cripple other jets. Any replacement must match that toughness and firepower while adding modern sensors and weapons. This is why the Air Force has tested multiple candidates over the past 15 years, and why no single replacement has been formally adopted yet.

Key Takeaways

  • The A-10 Warthog has been in service since 1976 and the Air Force has studied replacements for over a decade, but no formal successor has been selected.
  • Candidate aircraft include the F-35 Lightning II, the F-15E Strike Eagle, and experimental designs, each with different strengths in speed, payload, and survivability.
  • A replacement must match the Warthog's ability to fly low, carry heavy weapons, and survive enemy fire — requirements that no existing jet fully replicates.
  • The Air Force has tested multiple platforms in combat and training scenarios to measure which can best perform close air support missions.

Why the Warthog Needs Replacing

The Warthog was designed to fight Soviet tanks in Europe during the Cold War. It excels at that mission: the aircraft is built around a 30mm rotary cannon, has armor plating to protect the pilot and engines, and can loiter over a battlefield for hours. But the aircraft is now nearly 50 years old. Spare parts are harder to find, maintenance costs have risen, and the avionics — the electronic systems that help the pilot navigate and target — are outdated compared to modern jets.

The Air Force also faces a different threat environment than it did in 1976. Modern adversaries use air defenses that the Warthog was not designed to counter. Replacing the fleet would allow the military to use newer technology: better sensors, longer-range weapons, and systems that can share information with other aircraft and ground units in real time. However, the Warthog's low-altitude, low-speed performance is still valuable, and no replacement has proven it can do everything the Warthog does while also doing it better.

Aircraft Being Tested as Replacements

The F-35 Lightning II is the most widely discussed candidate. It is a modern jet with advanced sensors and can carry a variety of weapons. However, the F-35 is designed to fly fast and high, which is the opposite of how the Warthog operates. The F-35 also costs more per flight hour to operate, and pilots and ground commanders have raised questions about whether it can provide the same level of close air support in all weather conditions.

The F-15E Strike Eagle is another option. It is faster and more heavily armed than the Warthog, and it has been used for close air support in Iraq and Afghanistan. But the F-15E is also more expensive to operate and requires longer runways, which limits where it can take off and land.

The Air Force has also tested experimental designs and modified versions of existing aircraft. Some proposals involve keeping Warthogs in service longer while developing a purpose-built replacement over the next 10 to 20 years. Others suggest a mixed approach: retire some Warthogs and use a combination of F-35s, F-15Es, and other aircraft depending on the mission.

How the Air Force Tests Replacement Candidates

The military does not straightforward choose a replacement based on specifications on paper. Instead, the Air Force runs operational tests in which pilots fly candidate aircraft on realistic close air support missions. These tests measure how well each aircraft can find and destroy targets, how long it can stay over a battlefield, how much damage it can take, and how well it works with ground troops and other aircraft.

Test pilots and ground commanders provide feedback after each exercise. The Air Force also tracks maintenance costs, training requirements, and how quickly pilots can become proficient in each aircraft. This data is then compared to the Warthog's performance to see which candidate comes closest to matching or exceeding its capabilities.

Combat experience also informs the decision. The Air Force has used various aircraft for close air support in Iraq, Syria, and Afghanistan, and lessons from those deployments shape what the military looks for in a replacement.

Timeline and Current Status

There is no official date for when the Warthog will be retired or when a replacement will be fully deployed. The Air Force has extended the Warthog's service life multiple times over the past 20 years, and the aircraft is expected to remain in the fleet through at least 2030. Some Air Force leaders have suggested that a full replacement may not be ready until the 2040s.

Congress has also played a role in this timeline. Some lawmakers have pushed to keep the Warthog in service longer, citing its proven effectiveness and the cost of developing a replacement. Others have supported faster retirement and investment in newer platforms. Budget decisions, military strategy, and technological advances all affect when and how the replacement process moves forward.

What Replacement Means for Pilots and Bases

If and when the Warthog is retired, pilots currently flying the aircraft would transition to a new platform. This requires retraining, which takes several months. Bases that currently house Warthog squadrons would either be reorganized to support a different aircraft or see their mission change. Maintenance crews and support staff would need to learn new systems and procedures.

The transition would happen gradually, not all at once. The Air Force typically retires older aircraft over a period of years, bringing new ones into service in phases. This allows time for training, for bases to adjust, and for the military to assess whether the replacement is working as intended before committing fully to the change.

Frequently Asked Questions

Is the Air Force definitely retiring the Warthog?

The Air Force has stated that the Warthog will eventually be retired, but no firm date has been set. The aircraft has been extended multiple times, and it may remain in service through the 2030s or beyond. The decision depends on budget, military strategy, and whether a suitable replacement is ready.

Can the F-35 do everything the Warthog does?

The F-35 is more advanced in many ways, but it was not designed for the same mission. The Warthog is built to fly low and slow and carry a large cannon. The F-35 flies fast and high. Some military experts believe a combination of aircraft will be needed rather than a one-to-one replacement.

Why does the replacement process take so long?

Developing and testing a new military aircraft takes years. The Air Force must design the aircraft, build prototypes, run extensive tests, train pilots, and may support it meets military standards. Replacing an entire fleet of hundreds of aircraft takes even longer.

What happens to Warthogs that are retired?

Retired military aircraft are typically stored, sold to allied nations, or scrapped. Some Warthogs have been transferred to the Air Force Reserve or National Guard. A few have been preserved in museums.
