Japan is testing a 100 kW laser weapon capable of neutralizing drones and light projectiles, with tests scheduled for 2026.

Japan has begun testing a laser weapon with a power of 100 kilowatts, capable of destroying drones and light projectiles, mounted on the warship JS Asuka. This weapon combines ten lasers of 10 kW each, generating a laser beam capable of penetrating metal. The system, developed by Kawasaki Heavy Industries, was delivered to the Japanese Acquisition, Technology and Logistics Agency (ATLA) in February 2023 and will be tested in real maritime conditions starting from February 27, 2026. The weapon has an unlimited charging capacity, limited only by the availability of electricity, and lower operating costs compared to conventional systems. Although operational deployment is still years away, the tests will assess the potential use of more powerful lasers for missile interception. Japan joins other nations, such as the USA and France, in the development of directed energy weapons.
