As of 2020, railguns have been researched as weapons utilizing electromagnetic forces to impart a very high kinetic energy to a projectile (e.g. dart ammunition) rather than using conventional …

5 days ago · The Navy poured $500 million into a Mach 7 railgun that never deployed. Power, barrels, and China’s missiles killed it—leaving a brutal lesson for Pentagon planners.

Nov 25, 2025 · Discover how railgun technology works, the physics behind electromagnetic weapons, their power systems, advantages, and the future of EM military tech.

One solution is the electromagnetic rail gun, or rail gun for short. Using a magnetic field powered by electricity, a rail gun can accelerate a projectile up to 52,493 feet (16,000 meters) per …

Nov 3, 2022 · Rail guns use electrical power instead of chemical power to propel projectiles over long distances at hypersonic speeds. A linear motor device, this weapon typically uses …

Dec 13, 2024 · The feed mechanisms of a conventional firearm must move to accommodate the propellant charge as well as the ammunition round, while a railgun would only need to …

Key Points - While the US Navy abandoned its railgun program in 2021 after decades of research and over $500 million invested, primarily due to severe barrel degradation issues, Japan is...

Review the Navy’s Electromagnetic Railgun development, analyzing its revolutionary kinetic technology, strategic intent, and the decision to pivot resources away from the hardware.

We assess that railgun technology is undergoing an accelerating rate of development, with major programs in Japan, China, Europe, and other regions. While the US withdrew from its railgun …

A railgun or rail gun, sometimes referred to as a rail cannon, is a linear motor device, typically designed as a ranged weapon, that uses electromagnetic force ...
