A munition (10) with variable explosive power comprises a body (12) extending in an axial direction and housing at least first and second explosive charges (31, 32), together with a firing device (16). According to the invention, the munition further comprises a selector (50, 50′) provided with a detonating portion (52) and adapted to move between at least first and second positions, the selector being configured so that its detonating portion couples the firing device (16) to the first explosive charge in said first position and to the second explosive charge in said second position, one of the first and second explosive charges (31, 32) not being coupled to the firing device (16) in at least one of the first and second positions.

1. A munition with variable explosive power, the munition comprising a body extending in an axial direction and housing at least a first and a second explosive charge, together with a firing device, wherein said munition further comprises a selector provided with a detonating portion and adapted to move between at least a first and a second position, the selector being configured so that its detonating portion couples the firing device to the first explosive charge in said first position and to the second explosive charge in said second position, one of the first and second explosive charges not being coupled to the firing device in at least one of the first and second positions, wherein the selector is a rotary element having a first angular sector constituting the detonating portion and a second angular sector that is made of a non-detonating material. 2. A munition according to claim 1, wherein the first and second explosive charges are separated by a first non-detonating intermediate element. 3. A munition according to claim 1, wherein the first explosive charge is arranged in the vicinity of a front end of the munition, and the second explosive charge is arranged in the axial direction of the munition between the firing device and the first explosive charge. 4. A munition according to claim 3, wherein the firing device is separated from the second explosive charge by a second non-detonating intermediate element. 5. A munition according to claim 1, further including at least one primary pyrotechnic transmission unit coupling the first explosive charge to the selector. 6. A munition according to claim 1, further including at least one secondary pyrotechnic transmission unit coupling the second explosive charge to the selector. 7. A munition according to claim 5, further including at least one secondary pyrotechnic transmission unit coupling the second explosive charge to the selector, wherein the primary pyrotechnic transmission unit and the secondary pyrotechnic transmission unit are radially opposite to one another. 8. A munition according to claim 1, wherein the selector is configured in such a manner that its detonating portion couples the firing device to only one explosive charge at a time. 9. A munition according to claim 1, wherein the selector is configured in such a manner that in at least one of the first and second positions, the detonating portion couples the firing device to both the first and the second explosive charges. 10. A munition according to claim 1, wherein the selector is a rotary ring. 11. A munition according to claim 1, wherein the first angular sector constituting the detonating portion extends over an angle of less than 180°. 12. A munition according to claim 1, wherein the first angular sector constituting the detonating portion extends over an angle of not less than 180°. 13. A munition according to claim 1, further including a drive system for connecting the selector to a movable actuator element forming a portion of an outer covering of the munition, the movement of said actuator element causing the movement of the selector. 14. A munition according to claim 1, wherein each of the first and second explosive charges occupy substantially an entire diameter of the body. 15. A munition according to claim 11, wherein the first angular sector constituting the detonating portion extends over an angle lying in the range 30° to 150°. 16. A munition according to claim 11, wherein the first angular sector constituting the detonating portion extends over an angle lying in the range 90° to 120°. 17. A munition according to claim 12, wherein the first angular sector constituting the detonating portion extends over an angle lying in the range 210° to 330 °. 18. A munition according to claim 12, wherein the first angular sector constituting the detonating portion extends over an angle lying in the range 240° to 270°.
