I know they’re made to go off the radar but im still here wondering if they’re anywhere close to the Helicarriers in Avengers

So radar works by essentially sending out radio waves and “listening” to how they bounce back. Think about it like pushing a wave in water and locating rocks by the waves that bounce off of them and come back to you.

Stealth planes are shaped in such a way that they minimize this bounce back. Like a knife making minimal waves when you cut through water. Unless a government uses super sensitive equipment, it’ll be hard to locate.

There’s also a different technique they can use where they “listen” for the radar sound waves and use their own equipment to send out a sound to counter or cover up the bounce back. Although, I’m not sure how commonly used this technique is, because it’s super tricky to pull off.

Edit: I said sound waves, but it’s radio.
