Manufacturers will continue to build stealthy planes and drones, simply because it makes it harder to detect them. Yes, you may be able to detect a stealthy plane at, say, 100km, but using the same techniques you would be able to track a non-stealthy plane at 200km. Stealth isn&amp;#x27;t an end-all be-all tool that makes vehicles completely invincible, as the Bosnian shootdown of the F-117 showed, but it does make it harder, and I don&amp;#x27;t know of any technologies that could render it completely useless.</text><parent_chain><item><author>Someone1234</author><text>This isn&amp;#x27;t strictly just about a weakness in the F-35&amp;#x27;s radar resistance, but that the whole concept of &amp;quot;stealth&amp;quot; aircraft may be limited in the future thanks to ever increasing computation power and clever usage of existing radio waves (making effective, passive, &amp;quot;radar&amp;quot; that cannot be easily overcome).
