stealth aircraft

1, a very objective question, so there is data link and radio silence. In combat, pilots often passively receive information through radio or data links;

2. Stealth aircraft will have a set of radar identification equipment, which can be found by ground radar when opened and opened in combat airspace; In the early days, there was no such device. An American SR7 1 with a certain stealth capability could not be found by ground radar or tanker when it requested aerial refueling in Europe, and finally forced to land.

There are only a handful of stealth aircraft models. F 1 17 and B2 are both used to carry out ground attack missions. F 1 17 is also a subsonic aircraft, but B2, F22 and F35 are supersonic, and the latter two still have certain air combat capability, especially high-speed performance, but their close-range maneuverability and combat capability are obviously not as good as those of the conventional aircraft.

4. Vertical take-off and landing will consume a lot of fuel and take-off empty weight, so only the F35 Navy has this function.
