The Lockheed Have Blue was the code name for Lockheed's proof of concept (i.e. prototype) stealth aircraft that preceded the F-117 Nighthawk production stealth aircraft program. Have Blue was designed by Lockheed's Skunk Works division and tested at the top-secret Groom Lake base Nevada. The Have Blue was the first fixed-wing aircraft designed from an electrical engineering (rather than an aerospace engineering) perspective.
Made by Lockheed Corporation.
Lockheed Have Blue is the predecessor of the Lockheed F-117 Nighthawk.
