US Northern Command Warns Drone Defense Gaps Leave Military Bases Exposed to Domestic Swarm Attacks.

U.S. Northern Command says American forces lack sufficient sensors and effectors to reliably detect and defeat drone swarms launched from within the United States. The gap leaves military bases and critical infrastructure exposed to low-cost attacks that can bypass air defenses designed primarily for threats approaching from outside the country.

Lieutenant General Joseph Jarrard, deputy commander of U.S. Northern Command and vice commander of the U.S. element of NORAD, said at the Space and Missile Defense Symposium in Alabama on August 13, 2026, that some locations may have neither the sensors to detect an incoming drone swarm nor the effectors to stop it. NORTHCOM is integrating counter-UAS operations into Operation Noble Eagle while seeking greater interoperability between military sensors, law enforcement networks, and systems protecting civilian infrastructure. The Pentagon has requested about $21 billion for drones, counter-drone systems, munitions, and related capabilities as the services pursue electronic warfare, kinetic interceptors, high-energy lasers, and high-power microwave weapons to address the threat.

The challenge concerns both sensors and effectors. Some U.S. military installations may not have sufficient coverage to detect an approaching swarm of small drones, while systems capable of engaging them remain unevenly deployed. Detection therefore represents one of the main weaknesses in the current homeland defense posture. On August 13, 2026, during the Space and Missile Defense Symposium in Alabama, U.S. Army Lieutenant General Joseph Jarrard, deputy commander of U.S. Northern Command (NORTHCOM) and vice commander of the U.S. element of the North American Aerospace Defense Command (NORAD), said U.S. forces remained “ill-equipped” to address this type of threat. According to Jarrard, some areas may have neither the sensors required to identify an incoming swarm nor the effectors needed to neutralize it.

His comments point to a challenge that differs from the aerial threats traditionally addressed by NORAD. North America’s air defense architecture has historically been structured to detect aircraft, cruise missiles, and ballistic missiles approaching from outside the continent. A small commercial drone or loitering munition launched only a few kilometers from a military base creates a different operational problem, combining a limited radar signature, very low-altitude flight, short reaction times, and the potential simultaneous use of dozens of aircraft. The problem becomes more complex when drones are covertly introduced into the country before being launched. U.S. officials have increasingly referred to Ukraine’s Operation Spiderweb as an example of such a scenario. During the 2025 operation in Russia, Ukraine concealed drones near several air bases before launching them against Russian strategic bombers. An attack based on a similar approach could bypass much of the early-warning architecture intended to detect threats approaching from outside national territory.

Former NORTHCOM and NORAD commander General Glen VanHerck also stated in August 2026 that the United States was not prepared to stop a comparable attack. Repeated drone incursions over Langley Air Force Base in Virginia in 2023 had already exposed difficulties faced by U.S. authorities in identifying, tracking, and rapidly attributing the activity of small aircraft operating near a sensitive military installation. The spread of civilian drones creates an additional challenge. Unlike a missile or military aircraft, a small unmanned aerial system can be purchased commercially, transported in a vehicle, and launched from almost any location near a target. An attack could therefore reduce the interval between detection and impact to only a few minutes, or less, while making it more difficult to distinguish a hostile aircraft from civilian drone activity.

NORTHCOM is now seeking to integrate counter-drone operations more closely into Operation Noble Eagle, the U.S.-Canadian air defense framework established after the September 11, 2001 attacks. NORAD currently relies on existing radar systems while working to connect its networks with detection capabilities operated by other federal agencies, local law enforcement organizations, and authorities responsible for protecting critical infrastructure. For Jarrard, this level of interconnection is a central element of a future U.S. counter-UAS architecture. Military systems will need to exchange information with sensors and networks deployed outside military bases, including those protecting cities, airports, and strategic infrastructure. The issue therefore extends beyond acquiring additional effectors and includes the ability to establish a coherent chain linking detection, classification, command and control, and engagement.

The U.S. Department of Defense is also increasing investment in this area. The Pentagon has requested approximately $21 billion for drones, counter-drone systems, munitions, and related capabilities, while the individual services continue to assess a growing range of options intended to reduce the cost of each interception. Current responses are based on several complementary layers. Electronic warfare systems can disrupt the command links or navigation systems of certain drones, while kinetic weapons can engage aircraft able to continue operating despite jamming. The United States is also developing directed-energy weapons, including high-energy lasers and high-power microwave systems intended to engage multiple drones at a lower cost per engagement.

The U.S. Army is pursuing the Enduring High Energy Laser, or E-HEL, program, which is intended to transition work conducted over several years on laser weapons into a sustained operational capability. These technologies could provide a more economically viable option than routinely using missile interceptors against drones costing thousands or tens of thousands of dollars. However, they remain dependent on a detection and command architecture capable of identifying targets early enough and transmitting targeting data to the appropriate effectors. This requirement helps explain why NORTHCOM’s concerns focus as much on sensors and interoperability as on the weapons themselves. Deploying multiple independent counter-drone systems around sensitive installations does not necessarily provide an effective response to a saturation attack if radars, radio-frequency sensors, electro-optical systems, command centers, and effectors cannot exchange data in real time.

The vulnerability also contrasts with the objectives of the Golden Dome program, through which Washington plans to establish a homeland defense architecture against a range of ballistic, hypersonic, and cruise missile threats. While the United States is preparing major investments against strategic threats originating at long range, successive warnings from NORTHCOM indicate that a smaller, less expensive threat potentially launched from within the country remains difficult to counter. Operational experience from Ukraine and the Middle East has reinforced these concerns. The large-scale use of small drones shows that an adversary does not necessarily need to penetrate U.S. airspace with combat aircraft or long-range missiles to threaten an air base, logistics facility, or critical infrastructure site. A combination of modified commercial drones, autonomous systems, and saturation attacks could generate more targets than available detection and interception systems can handle.

Jarrard’s comments therefore indicate that the U.S. challenge extends beyond acquiring another counter-drone weapon. NORTHCOM is seeking an integrated architecture capable of detecting threats emerging at very short range, immediately sharing that information between military and civilian authorities, and assigning the most appropriate effector. Until such a detection and engagement chain is deployed on a broader scale, the proliferation of small drones will continue to expose a gap in a U.S. air defense structure historically organized against larger threats approaching from much greater distances.
