Infrared and radar wavelengths are completely different. Infrared does not use "radar" to return a thermal signature. Radar doesn't use infrared for vice versa. Mentioned materials can reduce the thermal footprint of an aircraft and the radar cross section can also be repeatedly reduced, but correlation is not causation. Materials that reduce thermal spin may also have a lower radar cross section. The Incredible Power of the B-2 Bomber. We know it as B2 but its full name is Northrop Grumman B-2 Spirit. It is one of the most powerful aircraft any country's military defenses have, but what makes it different from any other aircraft Its role is to be a stealth bomber, so it should come as no surprise that stealth is its number one priority. But how can an airplane traveling at top speeds of up to Mach 0.95 – almost at the speed of sound – hide so well Join us in this video as we explore the unrivaled power of the B2 Bomber.
