WASHINGTON, — April 10, 2026 : The U.S. Department of Defense has requested more than $2 billion in research, development, testing, and evaluation (RDT&E) funding for directed energy technologies in its fiscal year 2027 budget proposal, signaling an accelerated push to mature and field high-energy laser and high-power microwave systems across the military services.
The requested funding level represents a significant increase compared to historical benchmarks. During the Strategic Defense Initiative period between fiscal years 1985 and 1993, the United States spent approximately $4.9 billion in total on directed energy efforts, averaging about $500 million annually. The FY2027 request therefore exceeds that historical annual average by a wide margin, reflecting a shift toward operational deployment rather than exploratory research.
Integration with Golden Dome Missile Defense Initiative
A substantial portion of the requested funding is tied to the Pentagon’s Golden Dome missile defense initiative. The FY2027 proposal allocates $452 million for the development, integration, and assessment of directed energy systems supporting Golden Dome, more than triple the $142 million enacted in the previous budget cycle.
Golden Dome, a broader continental missile defense architecture announced in 2025, is allocated $17.5 billion overall in the FY2027 request. A significant portion of that funding is expected to depend on reconciliation legislation rather than the base defense budget.
Directed energy systems are being evaluated within Golden Dome for their ability to provide rapid-response, layered defense against cruise missiles, drones, and other aerial threats.
Service-Level Funding Increases
The budget proposal outlines notable increases across individual military branches.
The U.S. Navy’s directed energy and electric weapon systems RDT&E funding rises to $94 million, compared to $14.5 million in the FY2026 request. The Navy has previously deployed systems such as the Optical Dazzling Interdictor, Navy (ODIN) on surface combatants, and continues to explore integration of higher-power laser systems for shipborne defense.
The U.S. Army is advancing plans to formalize its first directed energy program of record. Under the Enduring High Energy Laser (E-HEL) program, the Army intends to produce and field up to 24 high-energy laser systems. This follows a decision not to transition the 300-kilowatt Indirect Fire Protection Capability–High Energy Laser (IFPC-HEL), also known as Valkyrie, into a formal acquisition program.
Instead, the IFPC-HEL prototype will serve as a technology demonstrator informing the Joint Laser Warfighting System (JLWS), a collaborative effort between the Army and Navy aligned with Golden Dome objectives, particularly for countering cruise missile threats.
Shift Toward Operational Deployment
Pentagon officials have indicated that directed energy systems are expected to transition from prototype and experimental phases to operational deployment at scale within the next three years. The emphasis is on systems capable of sustained engagement, with low per-shot costs and high magazine depth, particularly in response to the increasing use of unmanned aerial systems.
Lower-power laser systems have already been deployed by the Army in limited testing roles against drones, while the Navy has operational experience with optical and laser-based systems. The FY2027 request continues to prioritize RDT&E funding rather than large-scale procurement, indicating that technology maturation remains the immediate focus.
Industry Participation and Emerging Systems
The accelerated timeline for deployment has prompted increased activity among defense contractors and technology firms. Industry participants are expanding development and production capabilities to align with Pentagon requirements.
Among the systems positioned for potential integration is the “Archimedes” autonomous counter-unmanned aerial system, developed by Aurelius Systems. The platform combines sensor fusion and artificial intelligence to enable autonomous threat detection and engagement. Designed to operate using electrical power rather than conventional munitions, such systems aim to deliver low-cost-per-engagement performance and scalable deployment across distributed defense networks.
Budget Context and Next Steps
The directed energy funding request forms part of a broader FY2027 defense budget proposal totaling approximately $1.5 trillion, the largest in U.S. history. While the directed energy allocation focuses primarily on research and development, no major new procurement quantities beyond existing program lines are detailed in the current submission.
The budget has been released in a preliminary “skinny” format, with detailed justification documents expected later in April 2026. Congressional review and appropriations deliberations will determine final funding levels and program authorizations.
If approved, the FY2027 request is expected to further establish directed energy systems as a central component of future U.S. air and missile defense architecture, with expanded integration across land, naval, and joint operational frameworks.
