The Pentagon wants to field laser weapons at scale within 3 years

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.
