The US Department of War has awarded two Other Transaction Authority (OTA) agreements worth a combined $86 million to nLIGHT Defense and Lockheed Martin Aculight under the Joint Laser Weapon System (JLWS) program, kicking off a $847 million ceiling effort to field containerized high-energy lasers against drone swarms and cruise missiles.
Containerized 150 kW Lasers, Scaling To 500 kW
The first JLWS prototypes will fire at roughly 150 kilowatts to address urgent counter-UAS demands. Subsequent iterations are planned at 300–500 kW for cruise-missile defense, and a parallel 500 kW integrated system will use a laser source from the R&E directorate's High Energy Laser Scaling Initiative (HELSI). All variants use containerized form factors so they can be dropped onto ground vehicles or Navy hulls without redesign.
Fiscal 2027 budget documents earmark roughly $675.93 million in JLWS research and development funding over the next five years, keeping directed energy at the center of the Pentagon's homeland-defense modernization.
Why OTA And Why Now

The Department chose the OTA acquisition path to compress traditional procurement timelines, allowing rapid prototyping and iteration alongside industry. "We must actively defend the homeland against emerging threats," said Emil Michael, Under Secretary of War for Research and Engineering, framing the awards as a way to "rapidly deliver deep magazine directed energy capabilities to the Joint Force." JLWS is one of six Critical Technology Areas managed under R&E's Scaled Directed Energy (SCADE) portfolio.
Industrial Base: HELIOS, IFPC-HEL And Beyond
Both winners bring a decade of directed energy pedigree. Lockheed Martin has been prime contractor on the Navy's HELIOS laser aboard the destroyer USS Preble and on the Army's IFPC-HEL prototype. nLIGHT has led on HELSI, previously demonstrating a 300 kW coherent beam combining laser and receiving expanded funding to advance sources beyond the megawatt class.
The JLWS awards land the same week the Pentagon expanded AeroVironment's Titan counter-drone footprint and pushed further on the NATO Drone Edge counter-drone initiative. Together they signal a coordinated shift from kinetic-only interceptors toward a multi-tiered defense that mixes lasers, missiles, and cyber effects.
What Comes Next
Under the OTAs, nLIGHT and Lockheed will move quickly from prototype to demonstrator hardware, with the goal of transitioning JLWS into a production-ready platform that combatant commands can field. If the technology holds, the $847 million ceiling suggests the Pentagon expects laser weapons to become a routine base-defense capability rather than a one-off science project.
