Lockheed Have Blue

Lockheed Have Blue was the code name for Lockheed's demonstrator (i.e., "proof of concept") that preceded the F-117 Nighthawk production stealth aircraft. Have Blue was designed by Lockheed's Skunk Works division, and tested at Groom Lake, Nevada. The Have Blue was the first fixed-wing aircraft designed from an electrical engineering (rather than an aerospace engineering) perspective.The aircraft's plate-like, faceted shape was designed to deflect electromagnetic waves, greatly reducing its radar signature. Two flyable vehicles were constructed, but both crashed during the flight-test program.
