摘要： A weapon system includes a cartridge and a fire control apparatus have been developed for generating a projectile with a selectable launch velocity. The cartridge includes multiple primers and propellant chambers which may be individually selected by the fire controller so as to fire the projectile at a selected launch velocity. Additionally after firing the selected primers and propellant charges, the fire controller sends a second firing signal to all remaining primers after a suitable delay. The second firing signal ensures that all remaining propellant is initiated and consumed, thus rendering the cartridge safe to eject. The delay between the first firing signal and the second firing signal is sufficient to allow the projectile to be expelled from the cartridge so that the launch velocity is not affected by the combustion of the remaining propellant.
