Japan reached a new defense milestone in the summer of 2025 after successfully test-firing a high-power electromagnetic railgun at a moving naval target. According to the Acquisition Technology & Logistics Agency's (ATLA)
Instagram page, where it released images from the test, "It's the first time that a ship-mounted railgun was successfully fired at a real ship," bringing it a step closer to becoming the first nation to deploy next-gen railgun systems. ATLA first tested the weapon in 2023, following years of research and engineering validation that began in 2016. The prototype that was tested between June and July 2025 is installed on the JS Asuka vessel.
