...newest part of the offensive- Operation Intercept- is the largest search and seizure operation ever enacted in peacetime under civil authority...
...Egyptian plane was lost. The Israelis, citing photographic proof, said that seven Egyptian jets were downed and two more damaged, and admitted no losses. Over the next two days, when Israeli jets again lashed at Egyptian positions along the canal, Egyptian aircraft made only one attempt to intercept them...
...some time after it has been launched, calculates its path, and then passes the missile track along to the less powerful but much more complex MSR (missile site radar). MSR then directs two types of ABMs against the incoming warheads. The long-range Spartan is designed to make an intercept above the atmosphere, at altitudes between 200 and 400 mi. The smaller Sprint would seek out and destroy warheads that penetrated the Spartan screen by intercepting them within 40 miles of the target...
Cornell Physicist Hans Bethe, a Nobel laureate who believes Safeguard to be sound in principle but not yet necessary to U.S. defense, replies that it is possible to intercept the enemy warheads with Sprints at altitudes below 30 miles, where radar blackout is not a serious problem. Further, the PAR installations are designed to overlap enough for one to take over the functions of another -at least in theory-if the second is blacked out or even physically destroyed by a missile that penetrates the ABM defenses...
...together, which raises doubts about its reliability-especially since by its nature it can never be tested under conditions accurately simulating a nuclear attack. Wiesner also contends that any ABM is limited by the defender's guessing about the technology of the weapons it is designed to intercept. The attacker can add chaff and decoys as "penetration aids" to confuse the defender's radar and exhaust the supply of ABMs. Says Wiesner: "I do not think the defender is ever going to know really what to expect; the variety of techniques available to a nation planning an offensive...
