...Grand Trianon; Ronald Reagan will sleep in a suite once occupied by Louis Philippe, an eight-room apartment with floor-to-ceiling windows overlooking the canal and gardens. Some 3,000 guards will patrol the palace this weekend, and at the request of jittery U.S. officials, six antiaircraft missiles will be placed around the park. Frogmen have inspected every pool and canal for bombs and killer rabbits; the schedule allows for a late-afternoon gondola ride, if weather permits...
...armada at Ascension Island, the closest British staging area to the Falklands. That help has now been extended to cover a broad range of war goods, such as Sidewinder missiles, which the British could use to replace those fired by the task force Harrier jump jets, and Stinger portable antiaircraft missiles in U.S. Army supply depots in West Germany...
...that short-pulse radio waves reflected off the ionosphere, which provided the theoretical underpinning for radar. In 1933 he confirmed the existence of the neutron and was also able to measure the bonding forces in atomic nuclei. During World War II, he organized development of the proximity fuse for antiaircraft shells, enabling defenders to increase greatly their accuracy in combating German V-1 buzz bombs and Japanese kamikaze plane attacks...
Designed for helicopter launch, the missile is believed to have a range of about nine miles, greater than that of the antiaircraft weapons it is likely to encounter on its intended victims, small boats and patrol craft. To use it, a helicopter flies close enough to let its radar light up the target with radio energy, which, when reflected, provides a guiding point for the missile's homing computer. The Sea Skua streaks to its destination at over 550 m.p.h. and as little as 6 ft. above the surface. It is designed to penetrate the target before exploding...
...almost impossible to evade. A would-be victim can use electronic countermeasures like radar jamming to confuse the attacking missile's guidance system. A ship can also launch clouds of metallic strips from a special mortar to decoy its radar. Perhaps the best defenses are computer-guided antiaircraft guns and supersophisticated antimissile missiles...
