Eli5: What makes a stealth fighter harder to detect than a regular plane?

In: 284

Answer 1

The stealth aircraft are defined to fly at high altitudes, fly fast, and fly quietly, as well as have an odd shape to deflect a radar signal in such a way that it does not return to the source. This is what makes the aircraft so hard to detect through conventional methods.
