Japan has unveiled a prototype of a new vehicle-mounted high-energy laser system intended to bolster the Japan Ground Self-Defense Force's (JGSDF's) counter-unmanned aircraft system (C-UAS) capability.

The laser system was publicly shown for the first time at an event earlier in November to mark the 70th anniversary of the JGSDF in Saitama Prefecture. Footage of the event was published on social media by the JGSDF.

Speaking to Janes, a Japan Ministry of Defense (MoD) spokesperson said the system was developed for more than four years by its Acquisition, Technology & Logistics Agency (ATLA) in partnership with Mitsubishi Heavy Industries (MHI).

Following the production of the prototype, the spokesperson said the MoD is currently assessing the scope of potential procurement of the system for the JGSDF. “We have not decided on the number of units to be procured, [or] when and where to deploy them,” the spokesperson said.

The MoD spokesperson said the new laser C-UAS features a laser unit, a UAS detection and tracking system, a power supply unit, and a cooling device along with other associated systems. Media reports in Japan said the laser system can generate an output of 10 kW, although this has not been confirmed.

Janes assesses that the laser system is mounted on an MHI 8×8 heavy wheeled vehicle that weighs around 20 tonnes. The vehicle is approximately 11 m long, 2.5 m in depth, and 3.5 m in height. Trials of the system are likely to continue before any JGSDF procurement is announced.
