A cluster munition may include a plurality of submunitions that are ejected from a delivery vehicle. Each submunition is single target discriminating and includes electronic self-destruct and self-deactivate capability. Each submunition includes a microprocessor and a wireless communication device connected to the microprocessor. Each submunition includes a deployable antenna/stabilizer that functions as an antenna for the wireless communication device and as a stabilizer to stabilize the descent of the submunition. Optionally, the deployable antenna/stabilizer may also facilitate ejection of the submunition from the delivery vehicle. The submunitions may wirelessly communicate with each other and with other entities.

1. A submunition comprising: a submunition body including explosive material therein;a deployable antenna/stabilizer attached to the submunition body, the deployable antenna/stabilizer having a first end attached to the submunition body and a second end opposite the first end wherein, in a deployed state, the second end is distal the submunition body;a wireless communication device disposed on the submunition, the wireless communication device being electrically connected to the deployable antenna/stabilizer;a microprocessor disposed on the submunition, the microprocessor being electrically connected to the wireless communication device;means for determining a relative location of the submunition, the means for determining the relative location being electrically connected to the microprocessor; anda multi-mode fuze disposed on the submunition, the multi-mode fuze being electrically connected to the microprocessor, the multi-mode fuze including at least two of: (a) a proximity fuze for detonating the submunition in a selected proximity of the submunition to a target; (b) a point detonating fuze for detonating the submunition when contacting a target; and (c) a timer-based fuze for detonating the submunition after a selected time has elapsed, wherein the deployable antenna/stabilizer comprises at least one of a coil, a foldable flat spring and a drogue chute. 2. The submunition of claim 1, wherein the deployable antenna/stabilizer comprises one of the coil and the foldable flat spring, and further comprises the drogue chute wherein the drogue chute is attached to the submunition body with rigging lines. 3. The submunition of claim 2, wherein the wireless communication device is electrically connected to the rigging lines of the drogue chute. 4. A submunition comprising: a submunition body including explosive material therein;a deployable antenna/stabilizer attached to the submunition body, the deployable antenna/stabilizer having a first end attached to the submunition body and a second end opposite the first end wherein, in a deployed state, the second end is distal the submunition body;a wireless communication device disposed on the submunition, the wireless communication device being electrically connected to the deployable antenna/stabilizer;a microprocessor disposed on the submunition, the microprocessor being electrically connected to the wireless communication device;means for determining a relative location of the submunition, the means for determining the relative location being electrically connected to the microprocessor; anda multi-mode fuze disposed on the submunition, the multi-mode fuze being electrically connected to the microprocessor, the multi-mode fuze including at least two of: (a) a proximity fuze for detonating the submunition in a selected proximity of the submunition to a target; (b) a point detonating fuze for detonating the submunition when contacting a target; and (c) a timer-based fuze for detonating the submunition after a selected time has elapsed, wherein the deployable antenna/stabilizer comprises at least one of a coil, a foldable flat spring and a drogue chute, and, wherein the deployable antenna/stabilizer comprises the coil and the coil includes scoring in predetermined locations to define discrete sections thereof. 5. The submunition of claim 4, wherein the coil includes one or more projections extending therefrom to thereby increase an effective wireless transmission and reception range of the coil. 6. The submunition of claim 4, wherein the discrete sections include at least one curved section. 7. The submunition of claim 4, wherein the discrete sections include at least one straight section. 8. The submunition of claim 7, wherein the at least one straight section is disposed at the second end of the coil and extends radially beyond an external radius of the submunition body to thereby enable radio frequency communication with objects located below the submunition body. 9. A cluster munition comprising a submunition delivery vehicle having a main body portion with a plurality of the submunitions of claim 8 disposed in said main body portion, and wherein the delivery vehicle includes a wireless communication device and a microprocessor electrically connected to the wireless communication device. 10. A method, comprising: launching the cluster munition of claim 9; andejecting the plurality of submunitions from the delivery vehicle, and further comprising creating a wireless communication network between the wireless communication devices of the plurality of submunitions. 11. The method of claim 10, wherein creating the network includes creating a wireless communication network between the wireless communication devices of the plurality of submunitions and the wireless communication device of the delivery vehicle. 12. The method of claim 11, further comprising determining relative locations of the plurality of submunitions using each submunition's means for determining relative location. 13. The method of claim 12, further comprising sending target location information from the microprocessor of the delivery vehicle to respective microprocessors of each of the plurality of submunitions. 14. The method of claim 13, wherein the target location information includes a single desired target location for each submunition, a listing of all possible target locations, and a friendly/hostile identifier for each of the all possible target locations. 15. The method of claim 14, further comprising using each submunition's respective microprocessor and means for determining relative location to estimate the submunition's end location; then, comparing the submunition's estimated end location to its single desired target location; and then, executing a safe action if the estimated end location is not the single desired target location or if the desired target location has a friendly identifier. 16. The method of claim 15, wherein the safe action includes one of deactivating the submunition and detonating the submunition. 17. The method of claim 16, further comprising, for each submunition that reaches ground, wirelessly transmitting from the submunition information regarding location of the submunition and status of the submunition. 18. The method of claim 17, wherein the status information includes one of a pre-deactivation state and a pre-self-destruct state.
