...missile from the moment of blast-off at Russia's Tyuratam ICBM complex; the new radar will be fully operational in February and will give Washington 30 minutes' warning of a potential attack. The new three-stage Spartan anti-ballistic missile will also increase U.S. ability to intercept any incoming missile...
...will consist of five or six "perimeter acquisition radar sites" (PARS) along the northern U.S. border to identify and track incoming ICBMs. The radar sites will send information back to missile-site radar (MSR) equipment at 14 or so areas where long-range Spartan missiles will be poised to intercept enemy vehicles as much as 400 miles from their targets. Each Spartan battery will protect an elliptical area of the nation-in Pentagonese, a "footprint." Present plans call for batteries in each of the overlapping footprints, others in Alaska and Hawaii...
Each site will also have batteries of short-range Sprint missiles, designed to intercept, at ranges of up to 25 miles, any ICBMs that escape the clouds of X rays and neutrons laid down by the Spartans. In addition, five or six independent Sprint batteries will be deployed to protect the long-range radar sites and Minutemen in the U.S. Northwest. Though the number has not yet been determined, each Spartan site may have as many as 50 missiles...
...over-the-horizon" radar, now being perfected, to spot missiles as they leave launch pads in China or Russia, 30 minutes' flight time from the U.S. Once the onrushing rockets are detected, two types of antimissiles will be deployed. One is the long-range Spartan, designed to intercept enemy missiles 400 miles above the earth; the other is the short-range Sprint, whose job is to cope with any missiles that escape Spartan's nuclear net at levels under...
Assuming that such a disaster was nearly upon them, the M.I.T. students organized themselves into seven specialized groups to study the trajectories necessary to intercept Icarus, the space hardware and communications equipment that was available or could be quickly produced, and the effects of nuclear explosions. They consulted with leading physicists, used M.I.T. computers, and determined whether Cape Kennedy's launch-pad capacity could be expanded in time. The groups then coordinated their findings and, using systems engineering, devised a master plan to meet the threat of Icarus...
