The B2 Bomber is an amazing machine and years ahead of it’s time, but what made this revolutionary aircraft put the Stealth in Stealth Bomber?

First we need to understand how radar works. When a ground station is looking for aircraft it will send out pulses of light that will diffract off of an airplane and send that information back to the station giving away the aircrafts locations. The second thing it can do is look for infra-red radiation given off by the engine to detect an aircraft.

The B2 Bomber combats the light pulse by being covered in Electromagnetic Radiation (ER) tape and paint. It is also curved in almost every aspect which helps in redirecting the light emitted. The flat top and bottom will also re direct the light to a different location making sure it does not get back to the ground station. 

The B2 also prevents being seen in infra-red by enclosing it’s engine in the main body of the aircraft to hide the heat that is emitted. The exhaust also goes through cooling duct before exiting the aircraft  since the engine exhaust is a common place for high Infra-red emissions.

There are also other innovations taken to keep the aircraft hidden. It is exceptionally aerodynamic is so it will not make as much noise as it cuts through the air. Since the engine is embedded in the main body it is muffled. The B2 does not give off a smoke trail as it flies through the air. The tail has been removed to decrease drag and help with diffracting light. It can not reach Supersonic speeds so it is not capable of creating a sonic boom.
