A railgun concept is discussed in which a high pressure prefill of hydrogen serves as the close-in insulator between the rails. The Gas-Insulated Railgun (GIRG) may reduce or eliminate the velocity-limiting problem of growth and separation of the current-carrying armature region behind the projectile, and thus a low higher launch velocities to be achieved. A hybrid armature appears appropriate for this launcher.
