Abstract

An anti-missile missile for preventing an incoming threat missile from impacting a target without requiring impact of the anti-missile missile with the incoming threat missile. The incoming threat missile is provided with a guidance and control system disposed for receiving a source of guidance energy from an external source for guiding the threat missile to impact with the target. The anti-missile missile includes a body having a container carried thereby and a shield device carried in the container for ejection from the container in the vicinity of the threat missile. The shield device is disposed for controlling the amount of guidance energy received by the guidance and control system thereby rendering the guidance and control system ineffective to guide the threat missile to the target. An ejection device is provided for ejecting the shield device in the vicinity of the threat missile.

Claims

1. An anti-missile missile for "blinding" an incoming, threat, precision, seeker, guided missile in its trajectory to a target without requiring impact of said anti-missile missile with said incoming threat missile, said incoming missile having a guidance and control system and a seeker having an aperture through which energy which contains target information is directed to said guidance and control system of said threat missile, said anti-missile missile comprising:

a body having a container portion enclosing shield means, said shield means disposed for controlling the total energy received in said seeker aperture to alter the operational capabilities of said guidance and control system; and

means for ejecting said shield means from said container portion at a predetermined point in the vicinity of said trajectory, said shield means being a blinding material defined as a coating material which adheres to said seeker to prevent said incoming energy from entering said seeker.

2. An anti-missile missile as in claim 1, wherein said coating material is in the form of fine strands or strips that, on impact, adhere to said seeker.

3. An anti-missile missile for "blinding" an incoming, threat, precision, seeker, guided missile in its trajectory to a target without requiring impact of said anti-missile missile with said incoming threat missile, said threat missile having a guidance and control system and a seeker having an aperture through which energy which contains target information is directed to said guidance and control system of said threat missile, said anti-missile missile comprising:

a body having a container portion enclosing shield means, said shield means disposed for controlling the total energy received in said seeker aperture to alter the operational capabilities of said guidance and control system;

means for ejecting said shield means from said container portion at a predetermined point in the vicinity of said trajectory, said ejection means including means for rupturing at least a portion of said container portion of said missile for release of said shield means to the atmosphere, and

a pressurizing medium carried in said container portion for pressurization thereof to exert pressure on said shield means for release of said shield means from said container portion of said missile; and

said at least a portion of said container portion includes a plurality of ports disposed around the periphery thereof including cover members disposed for rupturing to release said shield means.

4. A system for defending against incoming threat missiles including a defensive missile for preventing an incoming threat missile from impact with a target without the need for impact between said defensive missile and said threat missile, said threat missile having guidance components, controlled by external energy signals and external trailing conductors for transmitting said energy signals to said guidance components, said defensive missile comprising:

a body having a container portion;

shield means carried in said container portion of said defensive missile, said shield means disposed for preventing said energy signals from reaching said guidance components of said threat missile, said shield means of said defensive missile including shorting means for creating a short circuit in said trailing wires to prevent said energy signals from reaching said guidance components of said threat missile; and

ejection means for ejecting said shield means from said container in the vicinity of said threat missile.

5. A system as in claim 4 wherein said shorting means comprises at least one strip of adhering material having electrically conductive members disposed therein.

6. A system as set forth in claim 4 wherein said guidance components of said threat missile includes a seeker aperture to receive said energy signals and said shield means includes means to alter the permissivity of said seeker aperture to prevent said energy signals from reaching the guidance and control components of said threat missile.

7. An anti-missile missile for preventing an incoming threat missile from impacting a target within the lower atmosphere without requiring impact of said anti-missile missile with said incoming threat missile, said incoming threat missile having a guidance and control system disposed for receiving a source of energy from an external source for guiding said threat missile to impact with said target, said anti-missile missile comprising:

a body;

a container carried by said body;

shield means carried in said container for ejection from said container in the vicinity of said threat missile, said shield means being an abrasive which crazes, cracks, or stoves the seeker to prevent said source of external energy from entering said seeker to thus limit the amount of said energy received by said guidance and control system ineffective to guide said threat missile to said target; and

ejection means for ejecting said shield means in the lower atmosphere in the vicinity of said threat missile.

8. An anti-missile missile for preventing an incoming threat missile from impacting a target without requiring impact of said anti-missile missile with said incoming threat missile, said incoming threat missile having a seeker provided with an aperture having a window and a guidance and control system disposed for receiving a source of energy from an external source associated with said target, through said seeker aperture window, for guiding said threat missile to impact with said target, said anti-missile missile comprising:

a body;

a container carried by said body;

shield means defined as silica material carried in said container for ejection from said container in the vicinity of said threat missile, said shield means disposed for physically altering said aperture window so that insufficient energy from said external source is passed therethrough for operational control of said guidance and control system thereby rendering said guidance and control system ineffective to guide said threat missile to said target; and

ejection means for ejecting said shield means in the vicinity of said threat missile.

9. An anti-missile missile for preventing an incoming threat missile from impacting a target without requiring impact of said anti-missile missile with said incoming threat missile, said incoming threat missile having a seeker provided with an aperture having a window and a guidance and control system disposed for receiving energy from an external source associated with said target, through said seeker aperture window, for guiding said threat missile to impact with said target, said anti-missile missile comprising:

a body;

a container carried by said body;

shield means carried in said container for ejection from said container in the vicinity of said threat missile, said shield means being a material capable of sustained incandescence before and at contact and disposed for physically altering said aperture window so that insufficient energy from said external source is passed therethrough for operational control of said guidance and control system thereby rendering said guidance and control system ineffective to guide said threat missile to said target; and

ejection means for ejecting said shield means in the vicinity of said threat missile.

10. An anti-missile missile as in claim 9 wherein said incandescence is provided by burning said material.
