A cartridge launched in an M203/M320 gun launcher device, which cartridge has fins of 1-5 inches in length to insure flight stability without spinning the cartridge. The non spin makes the cartridge capable of having a guidance navigation and control, canard actuating system added between the body and nose. The guidance navigation and control, canard actuating system features now make the cartridge suitable for successfully attacking stationary and moving targets not heretofore possible.

1. An enhanced stability extended range (guidance adaptable) 40 mm cartridge (100) comprising: a plug,a propellant holding cup,an enhanced cartridge case, anda 40 mm projectile comprising:a two part projectile holder cup,a rear obturator,an obturator holder cup,a tail cone,a rear fin housing,rear fins,a front fin housing,a body,an optional front obturator, anda nose. 2. The cartridge as in claim 1 wherein the fins are between 1 to 5 inches in length. 3. The cartridge as in claim 1 wherein overall projectile length are varied from 4 to 8 inches by varying the length of the tail cone, reducing the length of body, and/or by reducing the length of the nose. 4. The cartridge as in claim 1 wherein the projectile includes a guidance navigation and control, canard actuating system, added between the body and nose thereof. 5. The cartridge as in claim 4 wherein said included guidance navigation and control, canard actuating system makes possible the attacking of stationary and moving targets. 6. The cartridge as in claim 1 wherein the obturator holder cup is pressed onto the rear of tail cone tight against the rear fin housing, this preventing the fins from opening due to an interference fit. 7. The cartridge as in claim 1 wherein propellant gasses burn through a copper cup and escape through vent holes and are stopped by the obturator to propel an in-bore projectile to move rapidly through the gun tube to be launched. 8. The cartridge as in claim 7 wherein after the projectile leaves the gun tube, the two part projectile holder cup, rear obturator, and obturator holder cup, are all separated and discarded by flight air pressures. 9. The cartridge as in claim 8 wherein discarding of the projectile holder cup, rear obturator, and obturator holder cup enables the fins to open, at angles of 90 or 120 degrees. 10. The cartridge as in claim 9 wherein the fin blades have a canted angle to relatively slowly spin up the projectile during firing. 11. The cartridge as in claim 1 wherein the projectile carries a payload which includes any of: selected energetic materials, an explosive liner, fragmentation projectiles, or a selected warhead.
