The U.S. military’s proposed Joint Laser Weapon System, a U.S. Army-U.S. Navy effort first reported by Laser Wars in June 2025, would begin as a containerized 150-kilowatt laser with potential to scale to at least 300 kilowatts to counter cruise missiles, according to the Navy’s fiscal 2027 budget request.
Budget documents said the system would also include a Joint Beam Control System “capable of supporting” a 300-500kw laser weapon. The effort would draw on work from the Navy’s 60-kilowatt High Energy Laser with Integrated Optical-Dazzler and Surveillance (HELIOS), installed on the destroyer USS Preble, and the Army’s 300-kilowatt Indirect Fire Protection Capability-High Energy Laser, whose first prototype the service planned to receive later this year.
The Navy also said it would upgrade its High Energy Laser Counter Anti-Ship Cruise Missile Project test bed as needed to support future testing.
The Army’s fiscal 2027 request included no research and development funding for the program, after last year’s request detailed $51 million in mandatory funding through the One Big Beautiful Bill Act reconciliation bill. Instead, Army plans showed $337.8 million in spending from fiscal 2028 through fiscal 2031, suggesting it would complete work on its current laser effort first.
The Navy requested $94.825 million under its Directed Energy and Electric Weapon Systems account for fiscal 2027, up from $14.5 million in fiscal 2026. That included $79.84 million for its Surface Navy Laser Weapon System effort to begin Joint Laser Weapon System research and development, sustain HELIOS, and support test-bed upgrades, plus a separate $14.978 million for the High Energy Laser Counter Anti-Ship Cruise Missile Project.
Navy documents said the service planned to award $31.7 million in contracts for beam control development in the fourth quarter of 2026, and $30 million for procurement and testing of the containerized system by March 2027.
The budget request also included $452 million for “development, integration, and assessment” of directed-energy weapons supporting the Golden Dome missile defense initiative, though the connection to the joint laser program was not specified.
The technology has a long history of testing but limited fielded success against cruise missile-type threats. Navy documents said current funding would also begin a “consolidated implementation plan” for Golden Dome-related directed-energy efforts in coordination with the Missile Defense Agency.
