The invention, as embodied herein, comprises a kinetic energy driven projectile for defeating unexploded ordnance or buried land mines. This projectile has been developed to address the specific problem with similar devices in that the kinetic energy by itself does not sufficiently fracture the explosive material within a mine in order to fully defeat the mine. This invention adds a small amount of insensitive high explosive material but that is cap sensitive to one tip of the projectile, along with a novel initiation mechanism, so that the detonation of the high explosive material can more fully fracture the explosive material within a mine. This allows a neutralization agent to completely react with all of the explosive material within the mine, thereby consuming the entire fill.

1. A projectile for defeating a mine having a casing surrounding explosive material, comprising: an elongated body; a neutralizing agent at a first end; a second explosive material at a second end; a detonator proximate to the second explosive material; and, a backstop proximate to the detonator wherein the projectile penetrates through the casing and into the explosive material, deceleration causes the second explosive material to push into the detonator and the detonator to push against the backstop, activating the detonator, initiating the second explosive material, fracturing the explosive material without initiating the explosive material. 2. The projectile of claim 1, wherein the second explosive material comprises 77 percent HMX and 23 percent HTPB binder.3. The projectile of claim 1, wherein the second explosive material comprises a weight ranging from about 1.5 grams to about 2 grams.4. The projectile of claim 1, wherein the explosive material neutralizing agent is selected from the group of a surface contact chemical or a pyrotechnic mix material that will burn and consume the explosive material.5. The projectile of claim 1, wherein the backstop comprises at least one tab protruding from an interior surface of the elongated body.6. The projectile of claim 1, further comprising a location sensing means protruding from an outer surface of the elongated body.7. A method of defeating a mine having a casing surrounding explosive material, comprising the steps of: providing a projectile comprising an elongated body, a neutralizing agent at a first end, a second explosive material at a second end, a detonator proximate to the second explosive material, and, a backstop proximate to the detonator; and, propelling the projectile at the mine wherein the second end of the projectile penetrates through the casing and into the explosive material, deceleration causes the second explosive material to push into the detonator and the detonator to push against the backstop, activating the detonator, initiating the second explosive material, fracturing the explosive material without initiating the explosive material, and allowing the neutralizing agent to defeat the explosive material. 8. A method of defeating a mine having a casing surrounding explosive material, comprising the steps of: providing a projectile comprising an elongated body, a neutralizing agent at a first end, a second explosive material at a second end, a detonator proximate to the second explosive material, a backstop proximate to the detonator, and a location sensing means protruding from an exterior surface of the elongated body; and, propelling the projectile toward the mine, wherein the first end of the projectile penetrates the casing into the explosive material, stopping when the location sensing means contacts the casing, causing the second explosive material to push into the detonator and the detonator to push against the backstop, activating the detonator, initiating the second explosive material, fracturing the explosive material without initiating the explosive material, and allowing the neutralizing agent to defeat the explosive material. 9. A projectile for defeating a mine having a casing surrounding explosive material, comprising: an elongated body; a neutralizing agent at a first end; a second explosive material at a second end; a detonator proximate to the second explosive material; a location sensing means protruding from an exterior surface of the elongated body; and, a backstop proximate to the detonator wherein the first end of the projectile penetrates the casing into the explosive material, stopping when the location sensing means contacts the casing, causing the second explosive material to push into the detonator and the detonator to push against the backstop, activating the detonator, initiating the second explosive material, fracturing the explosive material without initiating the explosive materia l, and allowing the neutralizing agent to defeat the explosive material.
