A mine defeating projectile includes a housing defining an inner cavity, a plurality of channels extending through a front surface of the housing and to the inner cavity, and a plurality of cutout sections extending through as side wall thereof. The projectile further includes a fragmentation sleeve disposed in the inner cavity of the housing and a slider sleeve disposed in the inner cavity of the housing abutting an aft end of the fragmentation sleeve. The slider sleeve includes an explosive train and the slider sleeve is frangibly attached to the housing. The projectile further includes a finned section attached to an aft end of the housing. The finned section defines a protrusion for initiating the explosive train. The protrusion is spaced apart from the explosive train.

1. A mine defeating projectile, comprising: a housing defining an inner cavity, a plurality of channels extending through a front surface of the housing and to the inner cavity, and a plurality of cutout sections extending through a side wall thereof;a fragmentation sleeve disposed in the inner cavity of the housing;a slider sleeve disposed in the inner cavity of the housing abutting an aft end of the fragmentation sleeve, the slider sleeve including an explosive train, the slider sleeve being frangibly attached to the housing; anda finned section attached to an aft end of the housing, the finned section defining a protrusion for initiating the explosive train, the protrusion being spaced apart from the explosive train. 2. The mine defeating projectile of claim 1, wherein the housing includes a nose section defining closed, generally flat forward face. 3. The mine defeating projectile of claim 2, wherein the forward face is configured to supercavitate as the projectile travels through water or to create a terra-dynamic cavity when traveling through earthen materials. 4. The mine defeating projectile of claim 1, wherein the housing includes a nose section and the mine defeating projectile further comprises a frangible barrier disposed about an aft end the nose section for inhibiting water, air, or earthen materials from entering the plurality of channels defined by the housing until the projectile impacts a material of predetermined hardness. 5. The mine defeating projectile of claim 4, wherein the frangible barrier includes a plurality of sections separated by perforations. 6. The mine defeating projectile of claim 4, wherein the frangible barrier is configured to break apart upon impacting at least one of a material of a predetermined hardness, a metal mine housing, or an energetic fill of a mine. 7. The mine defeating projectile of claim 1, wherein the explosive train comprises: an insensitive energetic component;a sensitive energetic component; anda percussion primer that is initiated by impact with the protrusion. 8. The mine defeating projectile of claim 7, wherein the insensitive energetic component comprises a combination of octagen and vinylidine fluoride-hexafluoropropene polymer. 9. The mine defeating projectile of claim 7, wherein the sensitive energetic component comprises a deflagration-to-detonation material. 10. The mine defeating projectile of claim 1, further comprising an energetic column slider in which the explosive train is disposed, the energetic column slider being affixed in the slider sleeve. 11. The mine defeating projectile of claim 10, wherein the frangible attachment of the slider sleeve and the housing is configured to be defeated when an energetic fill of a mine impacts a forward face of the energetic column slider, resulting in the explosive train contacting and being initiated by the protrusion. 12. The mine defeating projectile of claim 1, further comprising a plurality of shear pins, wherein the housing and the slider sleeve define corresponding openings in which the shear pins are received to frangibly affix the slider sleeve in the housing. 13. The mine defeating projectile of claim 12, further comprising an energetic column slider in which the explosive train is affixed, the energetic column slider defining a plurality of openings corresponding to the plurality of opening defined by the slider sleeve, wherein the energetic column slider is disposed within the slider sleeve and the plurality of shear pins are received in the plurality of openings defined by the energetic column slider. 14. The mine defeating projectile of claim 13, wherein the explosive train comprises a percussion primer that is initiated by impact with the protrusion. 15. The mine defeating projectile of claim 1, wherein the fragmentation sleeve is configured to fragment, such that fragments of the fragmentation sleeve are expelled through the plurality of cutout sections defined by the housing. 16. A mine defeating projectile, comprising: a housing having a blunt nose section defining a generally flat forward face, the housing defining an inner cavity, a plurality of channels extending into the inner cavity, and a plurality of cutout sections extending through a side wall thereof;a frangible barrier disposed about an aft end the nose section;a fragmentation sleeve disposed in a forward end of the inner cavity of the housing;a slider sleeve disposed in the inner cavity of the housing abutting an aft end of the fragmentation sleeve;an energetic column slider disposed in the slider sleeve, the energetic column slider defining a cavity therein;an insensitive energetic component retained in a forward end of the cavity defined by the energetic column slider;a sensitive energetic component retained adjacent the insensitive energetic component;a percussion primer retained adjacent the sensitive energetic component;a finned section defining a protrusion extending from a forward face thereof, the finned section attached to the housing; anda plurality of shear pins engaged with the housing, the slider sleeve, and the energetic column slider, such that the percussion primer is spaced away from the protrusion.
