A railgun is a type of weapon that uses electromagnetic forces to launch projectiles at very high speeds. Unlike traditional firearms that rely on chemical propellants, railguns use electricity to create a magnetic field, which accelerates a conductive projectile along two parallel rails. This technology allows for greater range and impact compared to conventional weapons. Railguns are often considered for military applications due to their potential for high velocity and reduced logistical needs, as they do not require ammunition in the traditional sense. Research and development are ongoing, with interest from organizations like the U.S. Navy and various defense contractors.
