The U.S. military is once again pursuing flying directed energy weapons to counter threats to American airspace, according to the Defense Department’s missile defense boss.

Speaking to members of Congress during a House Armed Services Subcommittee on Strategic Forces hearing on April 15 on the Pentagon’s planned missile defense activities for fiscal year 2027, U.S. Missile Defense Agency director Air Force Lt. Gen. Heath Collins stated that his organization was “all in” on “bringing directed energy to the fight,” including integrating such weapons into unmanned platforms for domestic air defense against hostile missiles and drones.

“We are certainly putting more attention into bringing potentially game-changing directed energy capabilities to bear in an unmanned platform,” Collins stated in response to a question from Rep. Gabe Vasquez (D-New Mexico) regarding the MDA’s adoption of directed energy weapons.

“[An] air platform is what we’re focused on, so we can bring that capability to the edge of the fight and thin the herd on [unmanned aerial vehicles], potentially air threats and the like.”

While Collins did not identify specific directed energy capabilities of interest to the MDA, his written statement to the subcommittee notes that the agency is “accelerating the operational use of high-energy lasers on various platforms” to add a “critical, non-kinetic layer” to the existing U.S. missile defense architecture.

It’s unclear how much the MDA plans on spending on these efforts. While the “skinny” version at the Pentagon’s historic $1.5 trillion fiscal year 2027 budget request published in early April includes a significant boost to directed energy research and development for homeland missile defense under the Trump administration’s “Golden Dome for America” initiative, the documents do not contain any R&D or procurement efforts explicitly tied to the agency.

As Laser Wars readers likely already know, the Pentagon has been examining airborne laser weapons for missile defense since the 1970s, when the U.S. Air Force established its Airborne Laser Laboratory (ALL) program to explore the development of a laser-armed “aerial battleship” to protect strategic bombers from incoming interceptors.

In 2010, the service’s Boeing 747-based YAL-1 Airborne Laser Test Bed successfully destroyed several ballistic missiles in flight during testing but was subsequently canceled the following year due to “significant affordability and technology problems,” as then-Defense Secretary Robert Gates put it at the time.

As military laser weapons have evolved from bulky chemical-based systems to more compact and efficient solid-state designs in recent decades, U.S. military planners have increasingly explored integrating them into unmanned airborne platforms.

The High Energy Liquid Laser Area Defense System (HELLADS) effort, initiated in 2003 by the Defense Advanced Research Projects Agency, sought to develop a 150-kW system to integrate into both manned and unmanned aircraft before grinding to a halt in 2015.

The MDA itself pursued outfitting drones with laser weapons for ballistic missile defense for more than a decade through its Low Power Laser Demonstrator (LPLD) initiative before then-Undersecretary of Defense for Research and Engineering Michael Griffin threw cold water on the effort in 2020, citing the unique technical and environmental challenges inherent to mounting lasers on aircraft.

“I think it can be done as an experiment, but as a weapon system to equip an airplane with the kinds of lasers we think necessary — in terms of their power level, and all their support requirements, getting the airplane to altitudes where atmospheric turbulence can be mitigated appropriately — that combination of things doesn’t go on one platform,” Griffin told reporters in May 2020, per Breaking Defense. “So, I’m just extremely skeptical of that.”

Griffin isn’t wrong. Despite advances in laser technology, engineering a directed energy weapon that’s both powerful enough to destroy an incoming target and compact enough to integrate onto a relatively small airframe like a multirole combat aircraft or drone is a significant challenge.

Even if an integration were technically simple, operational feasibility is an major question: atmospheric conditions are limiting factors for laser weapons in any domain, but turbulence is a particularly thorny one for fast-moving airborne platforms tasked with maintaining a coherent beam long enough to successfully neutralize targets moving at equally high speeds.

Despite this skepticism, the dream of laser-armed drones appears alive and well. As recently as 2024, the MDA was gearing up for another run at airborne lasers, albeit with an initial focus on low-powered systems for tracking before ramping up to high-energy weapons.

In January 2025, the U.S. Navy released a slick vision of future naval operations that included notional drone wingmen outfitted with directed energy weapons running interference for manned aircraft. And in the last year, defense contractor General Atomics has released multiple renderings of its MQ-9B SkyGuardian and MQ-20 Avenger drones outfitted with laser weapons, although a company spokesman cautioned reporters that the systems were not designed for “any specific government program or contract.”

Directed energy weapons offer an alluring alternative to traditional missile-based air defenses, with low cost-per-shot, deep magazines and the ability to engage targets at the speed of light.

But the Pentagon has been here before: airborne laser concepts have repeatedly surged on waves of optimism, only to collapse under the weight of technical complexities and ballooning costs.

Indeed, the Air Force’s Airborne High Energy Laser (AHEL) and Self-Protect High-Energy Laser Demonstrator (SHiELD) efforts, which respectively sought to mount laser weapons on an AC-130J Ghostrider gunship and F-15 Eagle fighter jet, proved too challenging to even advance to airborne tests. (Undeterred, the service is poised to restart airborne laser efforts in fiscal year 2027 amid a surge in broad institutional support for directed energy. Time is a flat circle.)

Whether the MDA is barreling towards a genuine directed energy inflection point or just another familiar R&D cycle remains an open question.

For now, the message from Collins is clear: when it comes to determining whether airborne laser weapons are a viable missile defense capability, the U.S. military is once again willing to find out the hard way.

For decades, the U.S. military’s dream of high-energy laser weapons has been perpetually “five years away.”

Now, the Pentagon says it wants to finally make them an operational reality within the next three.

Speaking on a panel at the National Defense Industrial Association’s annual Pacific Operational Science and Technology conference in Honolulu, Hawaii, on March 9, Assistant Secretary of Defense for Critical Technologies Michael Dodd stated that the Defense Department plans on fielding directed energy weapons such as lasers and high-powered microwaves at scale within the next 36 months to defend service members from the threat of hostile drones, National Defense magazine reports.

While the Pentagon has deployed a handful of laser weapons overseas in recent years for operational testing and officially designated “scaled directed energy” as a critical technology area in November, this accelerated push for widespread fielding comes as U.S. forces engaged in the Operation Epic Fury struggle to counter waves of Iranian Shahed drones raining down across the Middle East, according to fellow panelist Deputy Under Secretary of Defense for Research and Engineering James Mazol.

“We need to be able to deal with mass, and we need to be able to defeat mass that’s coming at us,” Mazol said, per National Defense.

These ambitions appear to have support at the highest levels of the U.S. government. Speaking at a White House press conference on Epic Fury on March 9, President Donald Trump touted the potential of laser weapons as a cheaper alternative to the pricey interceptor missiles U.S. forces currently rely on to counter drones and other aerial threats.

“The laser technology that we have now is incredible,” Trump, who previously declared laser weapons a key feature of his proposed “Trump-class” battleship, said. “It’s coming out pretty soon. Where literally lasers will do the work of, at a lot less cost, what the Patriots are doing and what other things are doing.”

That cost difference is at the heart of the Pentagon’s growing interest in directed energy. A single Patriot PAC-3 interceptor can cost more than $3 million, while the Iranian Shahed drones pummeling battlefields across the Middle East often runs between $20,000 and $50,000 — a punishing asymmetry for conventional militaries.

Directed energy weapons like high-energy lasers promise to invert this equation, with each shot requiring little more than the electricity required to generate the beam. And while laser weapons have clear limitations, they offer a potentially attractive complement to traditional missiles and other kinetic interceptors for countering the threat of low-cost weaponized drones.

This Pentagon-level push to field directed energy weapons comes as the military services have accelerated their own laser programs. Senior U.S. Navy leaders recently trumpeted their vision of “a laser on every ship” in the surface fleet, a notable shift from the caution that previously defined the service’s approach to directed energy.

The U.S. Army has laid out draft requirements to “produce and rapidly field” up to 24 new Enduring High Energy Laser (E-HEL) systems in what might finally become the service’s first program of record. The Air Force is taking another run at both airborne laser weapons and ground-based systems for base defense after years of disappointment. The Marine Corps says it plans on investing in a “more deliberate program of record” for laser weapons, as a service spokesman previously told Laser Wars.

The Army and Navy are even teaming up on a brand new laser weapon system as part of Trump’s ambitious “Golden Dome for America” missile shield. All of this is occurring against the backdrop of $250 million infusion of funding for directed energy research and development included in the “One Big Beautiful Bill” reconciliation package the president signed into law in July 2025.

Taken together, these efforts may represent the Pentagon’s most serious attempt to transition laser weapons from experimental prototypes to routine military capabilities since President Ronald Reagan announced the Strategic Defense Initiative in 1983.

But while the R&D breakthroughs required for the orbital laser weapons envisioned by Reagan’s “Star Wars” never materialized, the technology has now advanced to the point where they are burning drones out of the sky in active conflict zones — and, occasionally, at home. Adaptive optics, more efficient power systems, improved thermal management and AI-assisted targeting have now converged to make laser weapons reliable and compact enough for real-world operations.

Transitioning laser weapons into fully funded military programs is as much a matter of institutional will as technological maturity. Many next-generation defense technologies end up languishing in the “valley of death” between R&D and acquisition because of shifting priorities or a lack of political support from stakeholders in the Pentagon or Congress; just look at the Navy’s experience with its electromagnetic railgun, which the service abandoned in 2021 after spending nearly $1 billion over two decades.

With senior military leaders, service secretaries and the commander-in-chief extolling the virtues of laser weapons, the chances of these systems actually watching over combat formations downrange have rarely been higher.

The most significant challenge facing the Pentagon’s scaled directed energy ambitions is the “scale” part. As Laser Wars previously reported, the essential components of laser weapons require rare earth elements and other critical minerals, the global production and processing of which China dominates.

And even if those inputs were abundant, advanced manufacturing capacity is not: U.S. defense contractors like AV and nLight, as well as Australia’s Electro Optic Systems (EOS), have all announced plans to boost production of laser weapons in recent months, but those manufacturing expansions will take months to ramp up and outputs will likely remain modest at perhaps a handful of systems a year (five to 10 annually at EOS’s new hub in Singapore, for example).

This pales in comparison to, say, the hundreds of FIM-91 Stinger missiles and Coyote interceptors that defense prime Raytheon can churn out in the same period. Scaling laser weapons from prototypes to scores of systems will require a defense industrial base that largely does not yet exist.

Scaled directed energy is not a standalone solution for the U.S. military’s air defense woes. Laser weapons, after all, aren’t magic: They can be extremely effective against drones and other targets, but they still require precious seconds of dwell time to inflict catastrophic damage and their performance can degrade depending on atmospheric conditions.

This makes them best suited as one segment of a broader layered air defense architecture rather than a wholesale replacement for missiles and guns. In practice, this means pairing lasers with kinetic interceptors, electronic warfare systems and other specialized countermeasures, all coordinated through a unified command-and-control system that can assign the right weapon to the right target at the right moment. Lasers and other exotic directed energy systems may help solve the cost problem posed by drone attacks, but only by working as part of a larger air defense ecosystem designed to handle the full spectrum of aerial threats.

After decades of laser weapons promises, the Pentagon has given itself a deadline. Now it has to prove that it can deliver — fast.
