Abstract
A gun system for launching a projectile that forms a component of a two-part payload that also includes a pusher that is separable from the projectile. The system includes a barrel, a source of propellant gas to propel the projectile and the pusher through the barrel, and a retarding coil and an accelerating coil, each having a coil axis parallel to the barrel axis and surrounding a projectile passage through the barrel, the retarding coil being disposed closer to the source of propellant gas than the accelerating coil. The retarding coil is configured to generate electromagnetic energy in response to passage of the pusher when being propelled by propellant gas ignition, and the accelerating coil is configured and coupled to impose an accelerating force on the projectile in response to the electromagnetic energy generated by the retarding coil.
