Lockheed Martin wins contract for a 500 kW containerized Joint Laser Weapon System prototype

Lockheed Martin said it has been awarded a contract to develop a tactical, containerized laser weapon system rated at 500 kilowatts under the Joint Laser Weapon System program. The company framed the work as part of a broader effort to build scalable, cost-effective defenses for combatant commanders, particularly against high-volume threats such as unmanned aerial systems and cruise missiles.

In a July 9 statement, Lockheed Martin said the U.S. Department of War awarded the company the JLWS effort to advance cruise-missile and unmanned-aircraft defense architecture for the next generation of U.S. joint operations. Under the program, Lockheed Martin will develop what it described as a “tactical containerized 500 kW laser weapon system,” designed to be used as an operational-tactical prototype.

Lockheed Martin also said the award recognizes its collaboration with SCALED Directed Energy, which the company described as one of the Department of War’s six Critical Technology Areas under the Office of the Under Secretary of War for Research and Engineering. That positioning matters because it indicates the program is tied to directed-energy technology priorities, rather than being purely a near-term procurement for existing systems.

The contract includes an emphasis on packaging and deployment, not just raw power. Lockheed Martin’s vice president and general manager for Sensors, Effectors, and Mission Systems, Paul Lemmo, said the prototype is “the highest-power laser ever packaged in a transportable container,” adding that the company’s work on lowering size, weight, and power and on rugged system design will allow containerized laser weapons to be built “in the near term.”

Lemmo’s comments point to a key engineering bottleneck for high-energy lasers used as weapons: getting sufficient power into a fieldable platform that can be transported, powered, and operated without the kind of laboratory-scale footprint that limits real-world use. Lockheed Martin said it has invested for more than 15 years in designing and fielding tactically relevant laser weapons, positioning this JLWS container concept as a step toward faster operational deployment.

Lockheed Martin paired those product claims with a cost-and-engagement argument. The company said that compared with conventional kinetic systems, directed-energy lasers provide a “speed-of-light” engagement, a “virtually unlimited magazine,” and a “dramatically lower cost per intercept” that is designed to be important for defeating high-volume UAS swarms and advanced cruise-missile threats.

A separate quote from Emil Michael, Under Secretary of War for Research and Engineering, characterized the award as part of an effort to “actively defend the homeland” against emerging threats. Michael said the program is aimed at partnering with industry to rapidly deliver “deep magazine directed energy capabilities” to the Joint Force, with the expectation that systems can be deployed across multiple domains.

In terms of what is and is not disclosed, Lockheed Martin did not provide contract value, work-share details, delivery milestones, or information about initial test targets in its statement. It also did not specify whether the 500 kW container will be tested as part of a particular exercise cycle or how the prototype maps to later stages of acquisition. Those elements will likely matter to bidders and oversight bodies evaluating how directed-energy prototypes transition to production systems.

Looking ahead, the immediate watch items are the program’s next technical milestones and any follow-on disclosures about evaluation results, integration requirements, and operational deployment concepts. For the defense sector more broadly, the award underscores how directed energy continues to move from demonstrations toward deployable architectures, with containerization and scalability emerging as central themes for counter-UAS and cruise-missile defense portfolios.
