Laser anti-missle defense system

Claim 1

A laser anti-missile defense system for producing coherent light energy to irradiate and destroy offensive attack missiles traveling within the atmosphere, irrespective of intervening atmospheric gases characteristic of said atmosphere between said system and said missiles, comprising: a multiple beam laser battery located on terra firma, said multiple beam laser battery comprising at least; a first chemical laser weapon to produce a first beam of continuous wave radiant heating energy of a given power level; a second chemical laser weapon to produce a second beam of continuous wave radiant heating energy of a given power level; with the power levels produced by said beams of said first and second laser weapons being sufficient in combination in intensity to at least weaken a spot of the wall of a missile located at the most distant portion of the atmosphere, irrespective of any effects of thermal blooming of said beams; said first laser weapon being spaced from said second laser weapon a predetermined distance sufficient to preclude said first and second beams from overlapping; mounting means at each of said predetermined locations for respectively mounting said laser weapons for universal targeting movement to permit the associated laser weapon to be independently aimed at any spot within a predetermined field of view within the earth's atmosphere over essentially non-overlapping beam paths; detecting means for detecting the presence and instantaneous position of an attack missile penetrating within said predetermined field of view for travel therethrough to provide position information on said attack missile as said missile travels within said field of view within said atmosphere; a point tracker means responsive to said position information for pointing each of said first and second laser weapons over substantially mutually exclusive first and second paths, respectively, extending from the respective laser weapon, at a spot on said attack missile, with said spot being located at a selected position behind the leading edge of said attack missile, whereby such first and second paths do not overlap away from the immediate vicinity of such spot, and tracking said spot during movement of said attack missile, whereby such first and second paths rotationally shift with movement of said attack missile; said pointer means comprising further: first pointer tracker means associated with said first laser weapon and second pointer tracker means associated with said second laser weapon; and firing means for simultaneously firing said first and second laser weapons to simultaneously direct continuous wave radiant heating energy from each said laser weapon to said spot on said attack missile for a predetermined duration sufficient to at least weaken said missile at said spot on said missile, whereby said missile may be destroyed.

Claim 3

The method of damaging an airborne moving target from within an atmospheric region, comprising the steps of: directing and maintaining a first continuous wave laser beam from a chemical laser onto a given area of said target to release radiant heating energy in said given area with said first laser beam originating from said first location; and simultaneously directing and maintaining at least a second continuous wave laser beam from a second chemical laser onto said given area of said target to release radiant heating energy in said given area with said second laser beam originating from a second location spaced from said first location, said spacing between said first and second locations being in an amount sufficient to preclude said laser beams from overlapping materially with one another away from the immediate vicinity of said target, wherein said laser beams essentially define two sides of a triangle having an apex at said given area on said target; and wherein said step of directing and maintaining said first laser beam includes the step of focusing a first pointer tracker at said target to aim said first laser beam at a selected position located a distance rewardly of the forward end of said target and said step of directing and maintaining said second laser beam includes the step of focusing a second pointer tracker at said target to aim said second laser beam at said same selected position on said target at which said first laser beam is aimed; said continuous wave laser beams releasing a combined radiant heating energy on said given area of said target sufficient in amount to at least melt or otherwise damage at least portion of said given area of said target, wherein the effect of said laser beams upon said given area is additive and results in damage to said target.

Claim 4

The method of damaging an airborne moving target from within an atmospheric region, comprising the steps of: directing and maintaining a first continuous wave laser beam from a chemical laser onto a given area of said target to release radiant heating energy in said given area with said first laser beam originating from said first location; and simultaneously directing and maintaining at least a second continuous wave laser beam from a second chemical laser onto said given area of said target to release radiant heating energy in said given area with said second laser beam originating from a second location spaced from said first location, said spacing between said first and second locations being in an amount sufficient to preclude said laser beams from overlapping materially with one another away from the immediate vicinity of said target, wherein said laser beams essentially define two sides of a triangle having an apex at said given area on said target; and wherein said step of directing and maintaining said first laser beam includes the step of focusing a first pointer tracker at said target to aim said first laser beam at a selected position located a distance rewardly of the forward end of said target and said step of directing and maintaining said second laser beam includes the step of focusing a second pointer tracker at said target to aim said second laser beam at said same selected position on said target at which said first laser beam is aimed; said continuous wave laser beams releasing a combined radiant heating energy on said given area of said target sufficient in amount to at least melt or otherwise damage at least portion of said given area of said target, wherein the effect of said laser beams upon said given area is additive and results in damage to said target.
