Japan has joined forces with France and Germany to develop electromagnetic railgun technology. This alliance, which includes the Japanese Ministry of Defense’s Acquisition, Technology, and Logistics Agency (ATLA), the French Ministry of Armed Forces, and the German Ministry of Defence, marks a significant step towards advancing this potentially game-changing weapon system.

The collaboration, outlined in a recently signed Terms of Reference (TOR) agreement, aims to leverage the combined expertise of the three nations. France and Germany, through the Franco-German Research Institute of Saint-Louis (ISL), are leading the charge in Europe with their PILUM project, a European Union-funded initiative dedicated to researching electromagnetic railgun technology. Japan, meanwhile, has been actively developing its own railgun capabilities since 2016, drawing upon its own research as well as lessons learned from the U.S. Navy’s long-running program.

Potential to revolutionize conventional artillery

The interest in this technology stems from its potential to revolutionize conventional artillery. Electromagnetic railguns can fire projectiles at velocities exceeding Mach 5, enabling them to travel significantly farther and with greater precision than traditional guns. Furthermore, they eliminate the need for explosive propellants, enhancing safety and reducing logistical complexities.

“There is much to learn from the US Navy’s experience, as they have invested heavily in research and developed numerous prototypes,” said a senior ATLA official, acknowledging the value of the partnership.

The ISL, renowned for its expertise in electromagnetic railgun technology, possesses various laboratory demonstrators, including the NGL-60 (New Generation Launcher) and the RAFIRA (RApid FIre RAilgun). These platforms offer valuable insights into the practical applications of railgun technology.

Japan’s involvement in the development of electromagnetic railguns is not limited to the European collaboration. Last year, Japan conducted the world’s first test-firing of a railgun from a Maritime Self-Defense Force vessel, achieving a projectile velocity of Mach 6.5. These developments highlight Japan’s commitment to advancing this groundbreaking technology.

The collaboration between Japan, France, and Germany underscores the growing global interest in electromagnetic railgun technology and its potential to redefine modern warfare.
