...almost daily for three weeks, Egyptian and Israeli artillery traded fire over the Suez Canal. Egyptian army commandos, their faces covered with grease, crossed the canal in rubber rafts, killing three Israeli soldiers in patrol-sized firefights. Roaring into Jordan, retaliating Israeli jets blasted two Egyptian-manned underground radar stations...
...most incredibly complex electronic-mechanical system ever built, with all the fallability such complexity implies. The ABM's reliability could never be tested under conditions approximating those of a nuclear attack, simply because there is no way of simulating all the conditions of a nuclear attack. For example, a radar system control the trajectories of the ABMs. We know that radar is affected in strange ways by nuclear explosions, but that is all we know. To accurately test the effectiveness of the ABM's radar system under actual attack conditions, we would have to explode large nuclear weapons all over...
...first pinpoints a radar site and then, by analyzing the signal picked up, determines just what that particular radar is used for. The experts can tell whether the radar under observation is meant to warn of possible threats from an enemy, whether it is intended to guide defensive surface-to-air missiles, or whether it is designed to control a network of offensive nuclear weapons. The aircraft's antennas, tuned to a wide range of radio frequencies used in military communications, can overhear conversations between major command posts 200 miles away and thus plot troop movements and combat readiness...
...ingenious way to test a potential enemy's alertness is known as "exercising." That means feeding a fake signal back to the adversary's tracking radar at precisely timed intervals to simulate an intrusion in his airspace. The defender is lured into sending his interceptors aloft and activates all his secret radar equipment to bag this fictitious intruder. Meanwhile, from a distance, the spy plane can carefully monitor everything that is done by the enemy in order to meet the electronically manufactured threat. There is no indication, however, that the downed EC-121 was "exercising...
...Most recently they have been keeping tab on the U.S. Sixth Fleet in the Mediterranean-sometimes flying with Russian markings, sometimes with Egyptian. A shorter-range reconnaissance airplane, the TU-16 Badger, until a year aeo made frequent flights down the Pacific coast of Japan to spy on Japanese radar installations; it earned the nickname "Tokyo Express." But since the sort of military information that is secret in Communist countries is often openly available in the West, the Soviet Union generally has an easier espionage chore than...
