Joint Laser Weapon System replaces shelved Army 'Valkyrie' and aims to fit on ships or in shipping containers

The U.S. military spent four decades chasing a laser that could shoot down a cruise missile. On April 28, 2026, the Pentagon detailed its latest attempt: the Joint Laser Weapon System, a containerized 150-kilowatt beam—scalable toward 500 kilowatts—that the Army and Navy will share, mounting it on trucks, ships, or anywhere a 20-foot container can sit.
The program absorbs the Army's recently shelved 300-kilowatt 'Valkyrie' laser and folds directed energy into the broader Golden Dome architecture authorized by Executive Order 14186. Combined Army and Navy spending is projected at roughly $675.93 million through fiscal 2031, with Lockheed Martin expected as prime contractor and first beam-control contracts due late 2026.
Why it matters
If the laser works, the U.S. gains a per-shot cost measured in dollars instead of millions—rewriting the math of cruise missile defense for ships and the homeland.

ClearanceJobs and other outlets amplify Gen. Guetlein's April 23 Fort Story remarks: 'Golden Dome is real. It is no longer theoretical. We are shovel ready and we're building it right now.' The coverage ties the declaration to the $3.2 billion in space-based interceptor contracts already awarded to 12 firms, framing Golden Dome as a program now visibly in motion.
The Washington Times reports that directed energy weapons (lasers) and non-kinetic 'left of launch' capabilities—cyber and electronic warfare tools designed to disable enemy missiles before they fire—are considered the greatest potential benefits of the Golden Dome architecture, with ground-based interceptors and space-based missiles as additional layers.

The Joint Beam Control System contracts award on time in late 2026, containerized 150-kilowatt units roll out beginning in 2027, and the Navy mounts variants on Arleigh Burke-class destroyers while the Army positions ground units around fixed sites. Lasers handle low-cost cruise missile and drone threats, freeing kinetic interceptors for higher-end targets.
Atmospheric distortion, target hardening, and dwell-time requirements that defeated Valkyrie reappear in JLWS. The 150-kilowatt baseline proves insufficient against fast, hardened cruise missile bodies, the 300–500-kilowatt scaling slips beyond FY2031, and the program is restructured or absorbed into a successor effort.
With Golden Dome's overall cost at $185 billion and space-based interceptor contracts already worth up to $3.2 billion, congressional appropriators cut the comparatively small JLWS line to protect higher-priority kinetic and space layers. Procurement targets fall well short of the planned 24 systems.
JLWS reaches initial deployment, but operational testing shows it reliably engages drones and small cruise missiles only at short ranges. The system is fielded as a complement, not an alternative, to Patriot, SM-6, and space-based interceptors—useful but not the cost-curve breakthrough advocates hoped for.
President Ronald Reagan announced a research program to build a layered shield against Soviet ballistic missiles, including space-based lasers, kinetic interceptors, and ground-based radars. The Strategic Defense Initiative Organization spent roughly $30 billion across a decade pursuing technologies—including the Mid-Infrared Advanced Chemical Laser, which destroyed a supersonic Vandal missile in 1989—but never delivered a deployed shield.
President Bill Clinton renamed the office the Ballistic Missile Defense Organization in 1993 and refocused it on theater defense after technology gaps proved larger than budgets could close.
Many SDI lines of work seeded today's missile defense systems, but the lesson of cost overruns and over-promised lasers shaped how Congress now scrutinizes architectures like Golden Dome.
JLWS sits inside a layered shield of similar ambition. The SDI experience is the reason cost growth and schedule slippage in Golden Dome draw immediate skepticism.
The Navy installed a 30-kilowatt solid-state laser, the AN/SEQ-3 Laser Weapon System, on the amphibious transport USS Ponce in the Persian Gulf. It became the first operationally deployed laser weapon, cleared by the fleet commander to engage drones and small boats.
LaWS demonstrated that a laser could be fielded, powered, and operated on a working warship without disrupting the rest of the ship's systems.
It established the modular, lower-power solid-state path the Navy has followed ever since, making a containerized 150-kilowatt JLWS a credible step rather than a leap.
JLWS's containerized, ship-deployable design is a direct descendant of LaWS. The class of problems—power, cooling, beam control at sea—is the same.
The Air Force and Missile Defense Agency mounted a megawatt-class chemical oxygen-iodine laser on a modified Boeing 747 to shoot down ballistic missiles in boost phase. The aircraft destroyed two test missiles in 2010, but the program had cost more than $5 billion and the operational concept required the jet to loiter near hostile territory.
Defense Secretary Robert Gates cut the program to a research effort in 2010, and the airframe was retired to the boneyard in 2012.
The cancellation pushed the Pentagon away from chemical lasers entirely and toward the solid-state, electrically pumped systems that JLWS now uses.
YAL-1 is the cautionary tale every laser-defense advocate confronts: a system can technically work, destroy real targets, and still be canceled if the operational concept and cost don't close. JLWS's containerized, multi-platform approach is partly an answer to that lesson.
