A launchable grenade system is backwards compatible with conventional launch platforms and is capable of launching a variety of payloads at greater range and increased launch velocity, and with significantly improved targeting accuracy. The grenade is pre-packaged in a disposable launch canister that effectively confines launch ejection gases behind the projectile until it exits the canister. Additional enhancements in one or more embodiments, include collapsible aerodynamic stabilizers that are folded inside the launch canister prior to firing and deploy in flight to improve projectile stability and ballistic performance; electronic fuzing for improved repeatability and targeting precision, next-generation digital capabilities that include electronic device identification, failsafe and device monitoring; and momentum arresting forward expulsion of the payload to reduce blunt trauma hazard from projectile hardware and to provide for short distance targeting at significantly greater speed.

1. A launchable grenade system, comprising: a launchable grenade having a lift charge, a lift charge ignition system, a fuze, a payload expulsion system, and a payload; anda disposable launch canister in which said grenade is packaged and from which it can be launched, configured to lock into a discharger tube of a conventional launch platform, said launch canister providing a closed base in which lift charge gases can be confined to increase launch thrust. 2. The launchable grenade system of claim 1, wherein said launch canister is configured to increase the blast handling capacity of said discharger tube to permit use of an enhanced lift charge. 3. The launchable grenade system of claim 1, further comprising a seal to confine launch gases behind said grenade in said launch canister until said grenade is propelled from said launch canister. 4. The launchable grenade system of claim 3, wherein said seal comprises an elastomeric material. 5. The launchable grenade system of claim 3, wherein said seal comprises an obturator ring. 6. The launchable grenade system of claim 3, further comprising a lift charge reservoir positioned at the base of the grenade around which said seal is provided. 7. The launchable grenade system of claim 6, wherein said lift charge reservoir is configured to separate from said grenade when it exits said launch canister. 8. The launchable grenade system of claim 1, wherein said launchable grenade system is electrically and mechanically configured for compatibility with existing launch platforms. 9. The launchable grenade system of claim 1, further comprising a collapsible aerodynamic stabilizer positioned on said grenade. 10. The launchable grenade system of claim 9, wherein said collapsible aerodynamic stabilizer is contained with said grenade in said launch canister to facilitate device storage, handling and pre-launch configuration. 11. The launchable grenade system of claim 9, wherein said collapsible aerodynamic stabilizer comprises a sliding ring encircling the body of said grenade and a plurality of collapsible fins extending therefrom. 12. The launchable grenade system of claim 11, wherein said fins comprise a resilient material. 13. The launchable grenade system of claim 11, wherein said aerodynamic stabilizer is configured to slide aft to form a radially flaring tail after said grenade exits said launch canister. 14. The launchable grenade system of claim 1, wherein said payload is expelled from said grenade in a forward direction that provides a deceleration of said grenade in flight. 15. The launchable grenade system of claim 9, wherein said aerodynamic stabilizer is configured to oppose a reverse thrust produced when said payload is forward expelled from said grenade. 16. The launchable grenade system of claim 15, wherein said aerodynamic stabilizer comprises a radially flaring tail. 17. The launchable grenade system of claim 1, wherein said payload is expelled from a substantially sealed compartment that is configured to dispense said payload with a reduced hazard of fragmentation and shrapnel. 18. The launchable grenade system of claim 17, wherein said substantially sealed compartment comprises a member that is configured to rupture at a predetermined pressure. 19. The launchable grenade system of claim 18, wherein said member that is configured to rupture at a predetermined pressure comprises a rupture diaphragm. 20. The launchable grenade system of claim 18, wherein said predetermined pressure is developed by a gas generator. 21. The launchable grenade system of claim 1, wherein said fuze comprises an electronic fuze. 22. The launchable grenade system of claim 21, wherein said electronic fuze comprises a controller that processes data and instructions comprising one or more of the following: performing grenade identification, launch initiation, time function, impact function, self destruct function; and determining grenade operability. 23. The launchable grenade system of claim 1, wherein said lift charge comprises an enhanced lift charge to provide greater thrust during launch. 24. The launchable grenade system of claim 1, wherein said launch canister is constructed to protect the grenade during storage and transportation. 25. A launchable grenade system, comprising: a launchable grenade having a lift charge, a lift charge ignition system, a fuze, a payload expulsion system, and a payload;a disposable launch canister in which said grenade is packaged and from which it can be launched, configured to lock into a discharger tube of a conventional launch platform and be substantially electrically and mechanically compatible therewith;said launch canister providing a closed base in which lift charge gases can be confined to increase launch thrust, and configured to increase the blast handling capacity of said discharger tube to permit use of an enhanced lift charge;a seal configured to confine launch gases behind said grenade in said launch canister until said grenade is propelled from said launch canister;a lift charge reservoir positioned at the base of said grenade around which said seal is provided; anda collapsible aerodynamic stabilizer contained in said launch canister configured to slide aft to form a radially flaring tail after said grenade exits said launch canister.
