Article Summary:
• Recent reports indicate that the Department of Defense (DoD) intercepted and brought down a Customs and Border Protection (CBP) drone utilizing laser technology.
• While the incident has captured public attention, Directed Energy Weapons (DEWs) have been in development by the U.S. government for decades, transitioning from experimental prototypes to active defense systems.
• Official government reports highlight the immense tactical benefits of DEWs, such as cost efficiency and scalable force, alongside potential challenges involving atmospheric interference, collateral effects, and ethical use.
• As the military scales these systems for wider deployment, an informed electorate must understand the capabilities, costs, and strategic implications of this fundamental shift in national defense technology.
Recently, reports surfaced that the Department of Defense utilized a laser system to shoot down a Customs and Border Protection drone. While an inter-agency incident of this nature is unusual and merits its own administrative review, the mechanism of the takedown—a military-grade laser—has sparked widespread public curiosity and, in some corners, confusion.
This is not the realm of science fiction, nor is it a sudden, secretive development. It is the result of decades of transparent, taxpayer-funded research and development. To have a substantive civic dialogue about how our military operates, how our defense budget is allocated, and what the future of warfare looks like, voters must understand the tools at our government’s disposal.
Transitioning from traditional kinetic weapons (like missiles and bullets) to Directed Energy Weapons (DEWs) represents a generational shift in defense strategy. By examining official government and military documents, we can objectively trace the history, present reality, and future potential of the technology that just made headlines.
Here is what official government sources say about the technology behind this recent incident:
The History and Development of Directed Energy Weapons
The systems capable of downing a drone today are the descendants of programs that stretch back through the Cold War. The goal has consistently been to develop defense mechanisms that operate at the speed of light.
• Decades of Research: “For decades, DOD has been developing DE weapons technologies that use electromagnetic energy to deny, degrade, damage, destroy, or deceive enemy weapons, equipment, facilities, and personnel.”

• Early Drone Interception: “Defined as a device such as a high energy laser or a high power microwave developmental system, the Air Force has a 40-year history of demonstrating the lethality of directed energy. In the ’70s, an Air Force Research Laboratory team went from testing laser fire at a variety of stationary targets to firing the lasers at moving airborne targets, to shooting down a drone…”

• Cold War Era Missile Defense: “In the 1970s and 1980s, U.S. scientists examined the development of missile defense satellites using nuclear-pumped Free Electron X-Ray and chemical powered lasers to defeat Soviet nuclear ICBMs, an ambition that became part of Ronald Reagan’s March 1983 Strategic Defense Initiative.”

Present Use and Present Concerns
Today, the military uses DEWs primarily for counter-unmanned aircraft systems (C-UAS). They offer a “graduated response,” meaning they can be dialed up or down depending on the threat. However, government watchdogs acknowledge that the technology still faces practical and ethical hurdles.
• Current Drone Defense Testing: “Throughout 2020, the 704th Test Group’s Operating Location AA, part of the Directed Energy Combined Test Force, or DE CTF, focused much of its effort on the testing of weapons designed to prevent adversarial drone observation and assault.”

• Scalable Force Options (Dazzling vs. Destroying): “DEWs can also degrade the efficacy of an enemy’s assets. For example, high energy lasers can temporarily overwhelm a person or a sensor’s ability to see or sense by emitting a glare—called dazzling. Dazzling can act as a non-verbal warning before resorting to increased force. If a greater amount of force is required, DEWs can also damage or destroy enemy assets. To do this, a high energy laser can emit electromagnetic energy with a wavelength the target material absorbs most effectively, melting the material…”

• Present Concern – Weather and Atmospheric Limitations: “Technological limitations. DEWs are generally less effective the farther they are from the target, and atmospheric conditions and cooling requirements can limit their effectiveness. For example, fog and storms can reduce laser beam range and quality.”

• Present Concern – Unclear Health Repercussions: “Ethical and health concerns. Although there are potentially relevant international laws and guidelines, their applicability to DEWs is not always well defined. Uncertainty around long-term health effects of DEWs on people either intentionally or unintentionally exposed to directed energy has led to concerns regarding the ethics of using DEWs.”

Potential Future Use and Future Concerns
As the DoD looks to the future, the goal is to scale these systems to counter larger, faster threats. This presents a massive tactical advantage—lasers cost mere dollars per shot compared to million-dollar interceptor missiles—but it also raises potential complexities for battlefield commanders.
• Scaling Up Systems: “At the current pace of technology development, you have to wonder where lasers weapons might be in 25 to 50 years… The numbers of systems, the power levels, and the operational utility will only increase from here.”

• Permanent Shift in Battlefield Dominance: “Even with a pessimistic estimate of the advance in DE science and technology, DE capabilities will have significant military utility in the battlespace of the future, due to the unique capabilities of DE systems in terms of precision, range, flexibility, scalability of effects, deep magazine, and active probing…”

• Future Concern – Collateral Area Damage: “Battlefield use. Decisions about how and when to use DEWs or conventional weapons may be challenging. For example, wider beam DEWs, such as high power microwave or millimeter wave weapons, affect all assets in an area, whether friend or foe.”
• Source: U.S. Government Accountability Office (GAO) – https://www.gao.gov/products/gao-23-106717
• Future Concern – Enemy Proliferation: “We maintain that we are approaching or have passed a tipping point for the criticality of Directed Energy (DE) capabilities as applied to the successful execution of military operations for the United States, Allies, and for the United States’ rivals and potential adversaries.”

The recent incident involving the CBP drone is a highly visible manifestation of an infrastructure the U.S. military has been building for decades. Directed Energy Weapons are no longer theoretical; they are an active, maturing component of our national defense strategy. They offer profound benefits, particularly in economic sustainability and deep magazine capacity against modern threats like drone swarms. Yet, as government watchdogs themselves note, they carry potential risks regarding ethical deployment, atmospheric limitations, and collateral effects that must be carefully managed.
As citizens and voters, our responsibility is to stay informed about these capabilities. The transition from kinetic to directed energy warfare changes the geometry of national security. By understanding the official research, current applications, and future trajectories of these weapons, we can better hold our elected officials accountable for how they fund, regulate, and deploy the technologies that protect our skies.
