A series of coordinated drone incursions over one of America’s most strategically significant air bases has exposed a critical vulnerability in U.S. homeland defense: the lack of effective, scalable air defense systems against low-cost aerial threats. The incidents, which unfolded over a one-week period in March, have intensified debate within defense circles about how the United States protects its own military infrastructure—and whether legacy platforms like the A-10 should be brought back into frontline service.
Between March 9 and March 15, waves of unidentified drones repeatedly entered the airspace over Barksdale Air Force Base, a critical installation that houses nuclear-capable B-52 Stratofortress aircraft. The drones appeared in coordinated clusters, typically numbering between 12 and 15 units per wave.
Military personnel reported between 60 and 75 drone sightings over the course of the week. Based on these figures, analysts estimate that organized drone swarms penetrated base airspace approximately five to seven times during that period. Each incursion lasted up to four hours—long enough to disrupt operations and demonstrate sustained presence.
Perhaps most striking was the behavior of the drones themselves. They reportedly operated with visible lighting systems activated, suggesting not stealth but deliberate signaling. Defense observers interpret this as a form of psychological and operational provocation, indicating that the operators were confident in the base’s inability to respond effectively.
The incursions occurred during preparations linked to a U.S. military operation referred to as “Operation Epic Fury,” reportedly involving bomber deployments toward Iran. Drone activity reportedly interfered with weapons loading operations and refueling logistics essential for long-range bomber missions.
In response, base command elevated its alert status to FPCON CHARLIE—the second-highest level in the Force Protection Condition framework. This designation typically indicates a credible threat of terrorist activity or imminent hostile action. Personnel were ordered to shelter in place, halting or slowing mission-critical processes.
While the B-52 sorties ultimately proceeded, the disruption may have had broader strategic implications. Analysts suggest that delays in refueling tanker coordination could have reduced operational tempo, while prolonged drone presence may have compromised operational secrecy. If adversaries were monitoring the situation, they could have gained early warning of U.S. strike preparations, allowing time to reposition assets or activate air defenses.
The United States has long invested heavily in air defense systems designed to counter high-end threats such as ballistic missiles. Systems like Patriot missile system and THAAD are optimized for intercepting fast-moving, high-altitude targets.
However, these systems are poorly suited for countering low-cost, low-altitude drones—particularly when deployed in swarms. The third layer of defense, the Ground-Based Interceptor system located in Alaska, is designed for intercontinental ballistic missile threats and is irrelevant in this context.
In practical terms, U.S. bases within domestic territory lack dedicated, layered defenses against small unmanned aerial systems (sUAS). While some electronic warfare tools are available, their effectiveness is limited.
At Barksdale, base personnel attempted to use signal jammers, but these proved ineffective. Reports indicate that the drones operated on frequencies beyond the range of available jamming equipment, rendering electronic countermeasures useless.
Compounding the technical gap is a lack of clarity regarding rules of engagement for domestic airspace. Military commanders face uncertainty about whether—and under what authority—they can engage aerial threats over U.S. soil.
In the Barksdale incident, the base commander reportedly did not authorize fighter aircraft interception, in part due to legal ambiguity and concerns about collateral damage. This highlights a structural issue: even if kinetic options are available, commanders may hesitate to use them without clear policy guidance.
The risk is not hypothetical. Missile-based interceptors, such as those used by Patriot systems, carry significant danger if they miss their targets. In March 2026, a Patriot system operated by the United Arab Emirates failed to intercept incoming Iranian missiles, which ultimately struck oil infrastructure in Fujairah. Similar incidents have occurred in other conflict zones, including Ukraine, raising concerns about debris and unintended impacts in populated areas.
One of the most pressing issues in counter-drone defense is cost asymmetry. Drones used in swarm operations can cost as little as a few thousand dollars per unit. By contrast, intercepting them with high-end missile systems is prohibitively expensive.
A single THAAD interceptor costs between $12.7 million and $15.5 million. Engaging a swarm of 12 drones could therefore exceed $150 million—assuming perfect interception rates. Patriot missiles, while less expensive at roughly $5 million each, still represent an unsustainable cost exchange.
This economic imbalance is a defining feature of modern warfare. Adversaries can deploy large numbers of inexpensive drones to overwhelm defenses, forcing defenders to expend vastly more resources per engagement.
Against this backdrop, attention has turned to an older, often-overlooked platform: the A-10 Thunderbolt II, commonly known as the Warthog.
Originally designed for close air support and anti-armor missions, the A-10 has several characteristics that make it well-suited for counter-drone operations. It is relatively inexpensive to operate—approximately $22,500 per flight hour, compared to $85,000 for the F-22 Raptor.
More importantly, the A-10 can be equipped with cost-effective munitions tailored for small targets. Chief among these is the Advanced Precision Kill Weapon System (APKWS II), developed by BAE Systems. This system converts unguided Hydra 70 rockets into precision-guided munitions using laser guidance.
Each APKWS-equipped rocket costs around $20,000—comparable to the estimated cost of many military-grade drones. This parity makes it one of the few economically viable countermeasures for swarm scenarios.
The A-10 can carry multiple rocket pods, each containing seven guided rockets, allowing it to engage numerous targets in a single sortie. Its loiter time and low-speed maneuverability further enhance its effectiveness in tracking and engaging small aerial targets.
Modern fighter aircraft such as the F-35 Lightning II and F-16 Fighting Falcon are less suited for counter-drone missions. These platforms rely primarily on air-to-air missiles, which cost close to $1 million per unit and are limited in number per aircraft.
Using such high-value assets against low-cost drones is inefficient both economically and operationally. Additionally, the high speeds of these aircraft can make it difficult to engage slow-moving or hovering drones.
A significant number of A-10 aircraft are currently in storage at Davis-Monthan Air Force Base, managed by the 309th Aerospace Maintenance and Regeneration Group. Estimates suggest that between 150 and 160 A-10s are stored there, including both A-10A and A-10C variants.
Of these, approximately 40 to 60 aircraft are classified as “Type 1000” storage—meaning they are maintained in near-flight-ready condition and have not been cannibalized for parts. These aircraft could potentially be reactivated relatively quickly.
Defense analysts propose assigning these A-10s to protect high-priority installations within the United States. Positioned at or near critical bases, they could provide a dedicated counter-drone capability without requiring the development of entirely new systems.
Reactivating A-10s for base defense would require more than technical readiness. Policymakers would need to clarify rules of engagement for domestic operations, particularly regarding the use of kinetic force in U.S. airspace.
Risk mitigation would also be essential. While APKWS rockets include self-destruct mechanisms to reduce the danger of unexploded ordnance, any aerial engagement carries some risk of debris or collateral damage.
Not all installations would be suitable for such defenses, especially those located near densely populated urban areas. Prioritization would likely focus on remote or strategically critical bases where the risk-benefit balance is more favorable.
Emerging technologies such as directed-energy weapons—particularly lasers—offer potential long-term solutions for counter-drone defense. However, these systems are not yet widely deployable at scale.
In the interim, the United States faces a clear and present challenge: adapting its defense posture to address a rapidly evolving threat landscape. The events at Barksdale underscore the urgency of this task.
Drone warfare has fundamentally altered the economics and tactics of aerial conflict. Without effective countermeasures, even the most advanced military infrastructure can be disrupted by relatively unsophisticated adversaries.
Revisiting legacy platforms like the A-10 may not be a permanent solution, but it represents a pragmatic step toward closing a dangerous gap—one that has already been exploited.
