Conclusion
War on Terrorism“Arm’s-length warfare”Primary Weapon: TomahawkOther guided weapons includedStand back and watch the results
ResultsExamples of guided weapon strikes:
How They Do ThatPhysical ControlsFins controlled by computer which
evaluates inputs from guidance systems
Initial Guidance SystemInertial Navigation System (INS)Easiest way from point A to B is a straight
line (or arc)Sensors determine tilt, roll and yaw as well
as acceleration and velocityComputer keeps memory of previous
motion and adjusts fins to keep on line or arc
Primary Guidance SystemGlobal Positioning System (GPS) INS has a habit of drifting due to error
compoundingGPS gives accurate positioning through
triangulation
Final Guidance SystemTerrain Contour Mapping (TERCOM)Used mainly for final approachAlso used at certain times during flightCan be used continuously for “ground-
hugging” flight, a la the TomahawkWorks by uploading pictures of target or
path before flight and comparing them to photographs taken during flight

ConclusionKeep US troops safe, which keeps public happyReason for US Military Supremacy in recent decades
