Special Coating
The lack of conventional navigational tools helped prevent the F-117 from showing up on radars. Moreover, the jet designers brushed a special coating around the exterior of the plane. This coating also prevented detection and made this plane extremely stealthy.

The F-117 didn’t carry any munitions externally like other aircraft. It still was armed with weapons such as infrared- or radar-seeking bombs and missiles that were deployed using laser guidance. It was such an advanced technology it shocked many people.
