...three have been built and a fourth will be completed in 1979-at a total cost of $4 billion. Three additional production models now under construction will probably be scrapped. The test models will be flown for several years, primarily to refine ultrasophisticated gear that jams enemy radar. This will make it easier to design manned bombers of the future-if any are built-that can penetrate enemy air defenses. Also, continuing the research will leave open Carter's option to change his mind in the event that technological breakthroughs or international political developments make the B-1 more...
Carter was also impressed by Pentagon reports that despite the B-1's speed of up to 1,320 m.p.h. and its ability to slip under enemy radar defenses, weapons advances would probably make it vulnerable to Soviet defenses by the 1980s...
...main considerations is the vast Soviet air defense network, largest in the world. Some 6,000 radar installations stretch from Murmansk to Vladivostok for early detection of a U.S. attack. The Soviet force of 5,000 interceptor aircraft includes 200 formidable MiG-25s, known as Foxbats, which have a top speed of 1,800 m.p.h. and a maximum altitude of close to 80,000 ft. In addition, the Soviets have about 12,000 surface-to-air missiles-low-level SA-3s and SA-6s and high-level SA-2s and SA-5s-at more than 1,000 sites...
...Soviets have a serious weakness: they have developed only a very crude "lookdown" radar, capable of spotting low-flying planes or missiles only over water. The U.S. has such radar in its Airborne Warning and Control System (AWACS) planes. The Soviets, however, have not yet figured out how to distinguish an airplane or missile from ground clutter. Before they solve this problem and deploy look-down radar (which may not happen until the 1980s), U.S. bombers will be able to penetrate Soviet borders...
...better chance than the B-52 of getting through Russian defenses. For one thing, it offers a smaller target for existing radar. It is only two-thirds the size of the B-52 (see chart). It can also fly faster and lower (600 m.p.h. at about 70 or 80 ft. above the ground). The B-l also is equipped with the most advanced black-box gear, which sends out electronic signals to counteract enemy warning systems. But critics maintain that when the Soviets develop new defensive weapons, including look-down radar and radar picket planes, like the AWACS...
