“Supersonic speed compromises stealth primarily because it generates strong shockwaves around the aircraft, which can be detected by radar systems, essentially giving away the aircraft's position and significantly reducing its stealth capabilities; this is due to the way the air interacts with the aircraft at high speeds, creating disturbances that can be picked up by radar.”
所以隐身战机实际作战时还是亚音速的,否则隐身要大打折扣。
所以B21的亚音速在实际作战时并不是什么缺点,因为大家都一样。
