The projectile according to claim 1, wherein the ignition flash column includes a flash hole disposed inside the cavity and a flash column opening which communicates with an outside of the projectile. 3. The projectile according to claim 1, wherein the rotary indexing disk respectively aligns the rotary indexing disk opening of the rotary indexing disk with the base plate nozzle so as to open the nozzle of the base plate and covers the base plate nozzle with a solid area of the rotary indexing disk so as to close the nozzle of the base plate. 4. The projectile according to claim l, wherein the nozzle comprises a plurality of nozzles and the opening comprises a plurality of openings. 5. The projectile according to claim 1, wherein at least one of the rotary indexing disk and the base plate includes a registration member and at least one of the base plate, the rotary indexing disk and the body includes a registration member accepting portion disposed such that the registration member is accommodated within the registration member accepting portion so as to control a range of rotation of the rotary indexing disk. 6. The projectile according to claim 5, wherein the registration member is positioned such that, if the registration member is disposed at a circumferential end of the registration member accepting portion, then the nozzle is open. 7. The projectile according to claim 5, wherein the registration member is positioned such that, if the registration member is disposed at a circumferential end of the registration member accepting portion, then the nozzle is closed. 8. The projectile according to claim 1, further comprising a holding member which is formed so as to prevent rotation of the rotary indexing disk until at least one of a predetermined torque and a temperature is achieved. 9. The projectile according to claim 1, wherein the base is formed such that the nozzle is openable by a rotational force of the projectile. 10. The projectile according to claim 1, wherein the rotary indexing disk is formed such that the rotary indexing disk is rotatable by a centrifugal force relative to the base plate. 11. The projectile according to claim 1, wherein the body further includes a payload cavity configured so as to be openable and closable to the cavity. 12. The projectile according to claim 11, wherein at least one of an oxidizer, a projectile propellant booster, an explosive material, a nuclear material or composition thereof, an organic compound, an inorganic compound, a chemical, a raw material, and a biological organism is disposed in the payload cavity. 13. The projectile according to claim 11, wherein a sealed ampule or an inert container is disposed in the payload cavity. 14. The projectile according to claim 1, wherein the nozzle comprises an opening angled such that, if a propellant gas volume is ejected from the nozzle, then a spinning force is imparted to the projectile or is maintained by the projectile. 15. The projectile according to claim 1, further comprising: a motor disposed in the projectile; anda driveshaft connecting the motor to the rotary indexing disk such that the motor controls an opening and closing of the nozzle. 16. The projectile according to claim 1, wherein the nozzle comprises a plurality of nozzles. 17. A munition, comprising: a cartridge case including a cartridge case propellant and an ignition system; anda projectile attached to the cartridge case, the projectile comprising: a body including a cavity;a propellant disposed in the cavity; anda base including; an ignition flash column extending into the cavity and a nozzle formed so as to be openable and closable;a base plate attached to the body including the nozzle; anda rotary indexing disk including an opening, rotatable in a circumferential direction in relationship to the base plate so as to open and close the nozzle of the base plate, respectively. 18. The munition according to claim 17, wherein the nozzle comprises a plurality of nozzles. 19. A method of assembling a munition, comprising: providing a cartridge case including a cartridge case propellant and an ignition system therein;providing a projectile body including a cavity formed within;inserting a propellant into the cavity of the projectile body;attaching a base to the projectile body to form a projectile, the base including an ignition flash column extending into the cavity and nozzle formed so as to be openable and closable, a base plate attached to the body including the nozzle, and a rotary indexing disk including an opening, rotatable in a circumferential direction in relationship to the base plate so as to open and close the nozzle of the base plate, respectively; andattaching the projectile to the cartridge case. 20. A method of assembling a munition according to claim 19, wherein the body includes a payload cavity, and wherein a material is inserted into the payload cavity prior to propellant insertion and attaching the base to the body.
