...last week's mission, the F-111s used 2,000-lb. bombs of the Paveway II ! class. The bomb's nose contains a laser-sensing device, a computer and small movable fins for stabilization and control. The sensor homes in on the reflection of the laser off the target; the computer moves the fins to make minute midcourse corrections. Each F-111 emits a laser at a different frequency, which only its bombs are programmed to detect...
...launch pads, which could take up to twelve hours. The U.S. missile can reach its target within ten minutes of launch. The Soviet rocket takes as long as three hours. Furthermore, the Soviets use a radar homing device that is easier to detect, and thus counter, than the heat sensor employed by the U.S. The Soviets are trying to develop an infrared homing system but their prototype has failed in six tests...
Local resident Marilyn Wellons said Harvard has little regard for a residential area already crowded with Peabody Terrace, Mather House, Leverett Towers and a near by sensor citizens highrise "The treatment of that building is symbolic of the treatment of this neighborhood," she added...
...novel gadgetry that made Homing Overlay successful is a sophisticated guidance system in the interceptor's warhead. It is able, thanks to a remarkable infrared sensor, to fix in space a target as small as a human being 1,000 miles away...
...missiles raced toward each other at a combined speed of 18,000 m.p.h., the interceptor's warhead expanded into an umbrella-shaped array of aluminum "ribs," 15 feet in diameter. As it turned out, the sensor aboard the killer rocket was so accurate that the ribs were unnecessary: the missiles themselves collided. The feat has been compared to one bullet hitting another, but, said Wilkinson, the two missiles were moving "about twice as fast as bullets...
