美国新型战略轰炸机B—1的设计目的是以低高度、超音速突防敌人空域,雷达几乎不能探测到它。第一架生产型飞机已于去年10月交付给空军进行飞行试验。B—1B的雷达特征信号只是其原型飞机B—1A的1/10,而B—1A的雷达特征信号又约
The new strategic bombers in the United States, B-1, are designed to penetrate the enemy’s airspace with low altitude and supersonic speeds, and the radar can barely detect it. The first production aircraft was delivered to the Air Force for flight tests in October last year. The radar signature of B-1B is only 1/10 of its prototype B-1A, and the radar signature of B-1A is about
