Anything in visual range could tell what it is rather quickly. Any SIG/ELINT capable aircraft would also be able to tell what it is. It also isn’t going to be flying without escort in any real use nor it’s ever intended to be used in contested or denied airspace. This just allows POTUS to be in a secure and mobile location while a more permanent solution can be found even tho it’s capable of being refueled in flight and has supplies for days if not weeks this isn’t intended to be used as a long term solution the engines can’t run indefinitely even if it constantly gets refueled.
