Military Implications of an SPS

TABLE 3-6. EARTH-TO-SPACE THREATS WEAPON TARGET PERIOD REMARKS HEL Spacecraft N-M Level of capability increases with time. PBW (neutral beam or pulsed charged beam) Spacecraft I The difference in exo- and endo-atmospheric propagation mechanisms make it unlikely that ground-to-space or space-to-ground attacks can be mounted. Orbital interceptor Spacecraft N Range beyond GEO. Conventional or nuclear warhead. Pilot beam Power satellite F(I?) Covert communications relay to other military facilities in space. Probably infeasible since cheaper, more effective means exist. RF transmitter Power satellite F(I?) Jamming, pied piper box. Feasibility depends on design of beam steering equipment. RF/Laser communication Spacecraft N Launch vehicles used for support Non-specific N Transportation of men and materiel, including ASAT weapons. Launch site used for support Non-specific N Alternate launch site for military vehicles-- existing facilities presently used for both purposes. Thus, this is not a new.threat which could cause concern and we ignore it.
