MHI 10kW Laser

Intelligence Summary: MHI 10kW Laser System

Node Identity: The MHI 10kW Laser is a vehicle-mounted 10 kW mobile laser weapon system developed by Mitsubishi Heavy Industries (MHI) for the Japan Ground Self-Defense Force (JGSDF). Initiated in 2021 under ATLA's (Acquisition, Technology & Logistics Agency) directed energy weapons program, the system is designed for counter-UAV operations with completion expected by March 2026. It represents the lower-power tier of Japan's two-track high-energy laser (HEL) development strategy, complementing the KHI 100kW-class system.

Strategic Relevance to FRC/Plasma Weapons Context: The MHI 10kW Laser's relevance to the plasma weapons network is its position within Japan's comprehensive multi-track DEW program, which simultaneously develops lasers, high-power microwave (HPM) weapons, and electromagnetic pulse (EMP) munitions — including the PLASMAGIC plasma generator. While the 10kW system itself is a conventional laser DEW for counter-drone operations, its development under ATLA places it within the institutional ecosystem that is also developing plasma-based weapons. Japan's DEW programs are further connected to the US through the US-Japan HPM Partners Agreement, which enables bilateral HPM testing at US test centers. The 10kW system provides the operational experience base for scaling toward higher-power laser systems with potential missile defense applications.

Technical Focus / Capabilities: The MHI 10kW system is a vehicle-mounted mobile laser weapon designed for C-UAS (counter-unmanned aerial systems) missions. Key parameters: 10 kW class laser output; vehicle-mounted for mobile deployment; JGSDF as the testing operator; ATLA as the contracting authority. The system was initiated in 2021 and is being tested by JGSDF with completion expected by March 2026. It was displayed at DSEI Japan 2025. The 10kW power level is sufficient for engaging small UAVs and surveillance sensors at short ranges but below the threshold for counter-rocket or counter-missile missions. The system represents Japan's entry-level operational laser DEW, providing a foundation for scaling to higher power levels.

Network Linkage: The MHI 10kW Laser maintains 5 documented connections: developer is MHI (Mitsubishi Heavy Industries, Japan's largest defense contractor); testing by JGSDF (Japan Ground Self-Defense Force); contracted by ATLA (Japan's defense procurement and technology agency). The system is part of ATLA's broader DEW portfolio that includes the KHI 100kW-class laser, HPM phased-array weapons (~$63M program FY2022-2026), EMP munitions (PLASMAGIC plasma generator), and electromagnetic railgun (2,300+ m/s, ship-based target strike). The US-Japan HPM Partners Agreement connects Japan's DEW testing to US facilities, creating a bilateral technology sharing pathway for plasma weapons development.
