Railgun

A railgun is a linear motor device that accelerates kinetic projectiles to extreme velocities. Conventional railguns use electromagnetic force to accelerate their projectiles, however some modern railguns also make use of mass de-simulation fields to enable a projectile to accelerate to higher and faster speeds than would normally be possible. Railguns are often used as weapons of war, but they also see use in deep space mining as a means to break up asteroids and comets. The Bowhead-class comet chaser utilized railguns for this purpose.
