A projectile (28) for a barrel assembly (10) containing multiple projectiles (28) including a propellant charge (22), a primer (23, 26) that ignites the propellant charge (22), a payload (28) that is propelled from the barrel (10) on ignition of the charge (22), and ignition system (20, 24, 25) havi
A projectile (28) for a barrel assembly (10) containing multiple projectiles (28) including a propellant charge (22), a primer (23, 26) that ignites the propellant charge (22), a payload (28) that is propelled from the barrel (10) on ignition of the charge (22), and ignition system (20, 24, 25) having both an electrical (20, 24) and a mechanical (25, 26) sub-system either or both of which may be triggered to ignite the primer (23). The electrical system may involve induction white the mechanical system may involve a solenoid or fully mechanical arrangement, the mechanical system acts as a backup for the electrical system if required.

The invention claimed is: 1. A barrel assembly including: a barrel with a plurality of projectiles aligned nose to tail for sequential firing, each projectile being associated with a propellant charge, a primer that ignites the propellant charge, and an ignition system triggerable to ignite the primer and thereby fire the projectiles; a plurality of firing systems, each firing system being for a respective projectile and including (i) a sensor for determining whether the respective projectile has successfully fired, and (ii) an induction coil coupled to the sensor, wherein the sensor is configured for detecting the respective projectile using a signal received from the coil; and a firing controller coupled to each of the firing systems, the firing controller being for operating the firing systems to thereby: determine whether or not a respective projectile is to be fired; and selectively trigger respective ones of the ignition systems to thereby fire associated ones of the respective projectiles. 2. A barrel assembly according to claim 1, wherein the firing controller is coupled to each firing system via a respective control line. 3. A barrel assembly according to claim 1, wherein each firing system is positioned on the barrel for triggering the ignition system of the respective projectile. 4. A barrel assembly according to claim 1, wherein each firing system is positioned on the barrel adjacent the respective projectile. 5. A barrel assembly according to claim 1, wherein the sensor is configured for detecting a magnetic field associated with the projectile. 6. A barrel assembly according to claim 5, wherein each projectile includes a magnet. 7. A barrel assembly according to claim 1, wherein the firing controller is configured to operate the firing systems to determine whether or not the respective projectiles are to be fired by determining from the sensor whether the respective projectiles have been successfully fired. 8. A barrel assembly according to claim 1, wherein the sensor is configured for activating the coil to thereby inductively trigger the ignition system. 9. A barrel assembly according to claim 1, wherein the induction coil is at least one of surrounding and embedded within the barrel. 10. A barrel assembly according to claim 1, wherein each ignition system includes an SCB embedded in the primer that is triggered by induction from the coil. 11. A barrel assembly according to claim 1, wherein the firing controller is configured for generating coded signals, the firing system being configured for: receiving the coded signals; and, selectively triggering the ignition system. 12. A barrel assembly according to claim 11, wherein the coded signal is configured for determining a manner in which a projectile is to be fired. 13. A barrel assembly according to claim 1, wherein the firing controller is configured for generating a coded signal and the coded signal is conveyed to the ignition system by the induction coil, and wherein the ignition system is configured for detecting the coded signal and igniting the primer. 14. A barrel assembly according to claim 1, wherein each ignition system has a backup firing system. 15. A barrel assembly according to claim 14 wherein each firing system incorporates a solenoid having a core that operates through the barrel as a firing pin. 16. A barrel assembly according to claim 14 wherein each firing system has a firing pin that operates through the barrel in response to movement of a sliding shaft adjacent to the barrel. 17. A barrel assembly according to claim 14 wherein each ignition system includes an auxiliary primer that is triggered by a firing pin in the barrel. 18. A barrel assembly according to claim 1, wherein each ignition system has both an electrical and a mechanical subsystem either or both of which is triggerable to ignite the primer. 19. A barrel assembly according to claim 13, wherein the coded signal is configured for determining a manner in which respective ones of the projectiles are to be fired.
