US EditionJapan's Massive Ship-Mounted Railgun Just Fired A History-Making Shot
The Acquisition Technology & Logistics Agency highlighted the cost efficiency and high speed of railgun rounds reaching 4,500 mph during tests on the JS Asuka experimental warship.
- Japan's Acquisition, Technology & Logistics Agency conducted a ship-mounted railgun firing test against a moving naval target on JS Asuka between June and early July 2025.
- This test followed years of research since 2016 and occurred as the U.S. Navy ended its railgun program in 2021 due to feasibility issues.
- The railgun accelerated projectiles up to Mach 6 without explosive propellants, hitting a real ship and showing adjustable speed and range per mission needs.
- According to ATLA, a ship-mounted railgun was fired at an actual vessel for the very first time, with projectiles reaching speeds of 4,500 mph, which could provide significant benefits for missile defense.
- This milestone suggests Japan leads railgun development while the U.S. shares its older equipment with universities for further study and China advances similar technologies.

The U.S. Navy’s Big Railgun Failure Still Stings
It was to be the naval weapon technology of the future, holding the tantalizing promise of very low per-shot shots, deep magazines, high precision, and long range. In 2007, the U.S. Navy even wrote that the tech represented the “next generation of naval guns.” The weapon in question? The railgun. And yet, years later, the U.S. Navy still fields no railgun, while Japan is making significant strides in this technology. Why? What Is a Railgun? The …

Electromagnetic cannons are capable of firing missiles at hypersonic speed that cannot be stopped by current defense systems
The Japanese Navy announced the successful test of what it claimed was the world's first electromagnetic cannon. The article "Electromagnetic Weapon. How Does It Work? The Japanese Test It" comes from the website Wszystko co mojego.
Japan has just made history by firing for the first time an electromagnetic cannon, known as “railgun”, mounted on a warship. This achievement inaugurates a new stage in military technology, marking the probable transition from gunpowder to the destructive power of electromagnetic physics. It must be remembered that the United States tried to develop this technology for decades, but ended up abandoning the project by technical obstacles. Japan, …
