New plasma stealth device targets specific areas, not entire aircraft.
According to a recent report from the South China Morning Post, Chinese scientists and engineers claim to have developed a plasma stealth device for military aircraft that is capable of rendering nearly any such aircraft undetectable by radar.
If you can’t make the whole plane with angled surfaces, at least add a cover to the rounded parts. Makes sense.
Still an interesting move to cover the radar dome with radar absorbing plasma, effectively blinding the plane itself…
…but if it can also be de-activated quickly, then it could make sense.
