Pentagon Accelerates Scaling of Military Laser Weapons for Golden Dome Defense

The U.S. Department of Defense is attempting to move high-energy laser weapons from experimental prototypes to mass-producible capabilities within the next two years. The push is driven by a shift in focus from fundamental science to the engineering challenges of scaling these systems for actual battlefield deployment.

During testimony before the Senate Armed Services Committee’s Emerging Threats and Capabilities Subcommittee on May 19, 2026, Emil Michael, the undersecretary of defense for research and engineering, stated that the science behind laser weapons is largely done. He indicated that the Pentagon is now prioritizing the transformation of exquisite prototypes into capabilities that can be produced at scale.

This acceleration is closely tied to the Golden Dome for America initiative, a domestic missile shield planned by President Donald Trump. According to Michael, the initiative relies heavily on directed energy, which has provided a political and financial catalyst for research, and development.

The fiscal year 2027 budget request reflects this priority, proposing $452 million in research and development spending specifically for the development, integration, and assessment of directed energy weapons to support the Golden Dome architecture. This figure is more than triple the $142 million previously enacted under the One Big Beautiful Bill Act reconciliation package signed in July 2025.

Beyond the domestic shield, operational urgency is being driven by regional conflicts. Michael noted that U.S. Experiences in Iran have doubled the Pentagon’s interest in these systems, leading to a push for weapons that are smaller, cheaper, and more proliferated.

However, the transition from laboratory success to field readiness has historically been the primary point of failure for U.S. Military laser programs. While the Pentagon has successfully used lasers to disable drones since 1973, creating a weapon that can be maintained by non-specialists in harsh tactical environments remains a significant hurdle.

A primary example of this engineering gap is the Army’s 50 kW Stryker-mounted Directed Energy Maneuver-Short Range Air Defense (DE M-SHORAD). Following operational testing in the Middle East in 2024, the service determined the system was not mature enough to become a program of record due to reliability issues and failures in heat dissipation when mounted on a vehicle.

The last decade has seen several other promising programs fail to reach full deployment:

• The Army abandoned its 300 kW Indirect Fire Protection Capability-High Energy Laser project, reducing it to a single testbed.
• The Navy’s 60 kW High Energy Laser with Integrated Optical Dazzler and Surveillance system has largely disappeared from the fiscal year 2027 budget request, despite successful drone engagements aboard the USS Preble.
• The Marine Corps returned five Compact Laser Weapon System units to Boeing without a replacement program.
• The Air Force abandoned Raytheon’s High-Energy Laser Weapon System after years of testing without establishing a program of record.

A 2023 Government Accountability Office report attributed these failures to a lack of formal transition partners and a failure to establish binding agreements regarding requirements and funding across different budget cycles. Secretary of Defense Pete Hegseth described this pattern as institutional inertia in an April posture statement to the House Armed Services Committee.

To break this cycle, the Pentagon is focusing on two primary efforts that may indicate whether current engineering confidence is justified. The first is the Enduring High Energy Laser (E-HEL), a modular 30 kW system designed as the Army’s first directed energy program of record.

The E-HEL is designed to avoid the pitfalls of the DE M-SHORAD by decoupling the system from a specific vehicle platform and utilizing line-replaceable units for easier maintenance by soldiers. The Army plans to field 24 E-HEL systems over five years, with a prototype expected by the second quarter of fiscal year 2026 and initial procurement units due by the end of fiscal year 2027.

The second effort is the Joint Laser Weapon System (JLWS), a containerized 150-300 kilowatt system. The Navy plans to award $31.7 million in contracts for a Joint Beam Control System—capable of supporting 300-500 kW lasers—by the fourth quarter of 2026, with hardware procurement and testing contracts expected by March 2027.

While these timelines make a Golden Dome demonstration in the summer of 2028 plausible, the JLWS R&amp. D roadmap extends through fiscal year 2031, suggesting that any 2028 demonstration would feature an early-stage weapon rather than a fully mature system.

Supply chain vulnerabilities also pose a risk to the Pentagon’s scaling goals. Specialized optics currently have lead times ranging from 12 to 18 months, and critical rare earth elements remain heavily sourced from Chinese-dominated supply chains, potentially limiting the speed of mass production.

The pursuit of directed energy has long been characterized by a cycle of high expectations followed by disappointment. As noted by retired Air Force general Ellen Pawlikowski in a 2018 interview with the book Lasers, Death Rays, and the Long, Strange Quest for the Ultimate Weapon:

I’m tough on laser people these days. It’s because they have a reputation of overpromising and underdelivering.

The planned 2028 demonstration will serve as a critical test of whether the U.S. Military has finally solved the engineering hurdles that have stalled laser weaponry for decades.
