The Lockheed Have Blue was the code-name for Lockheed's "proof of concept" Stealth Fighter program that preceded the F-117 Nighthawk production stealth aircraft project. Designed by Lockheed Advanced Development Programs, now Lockheed Martin Advanced Development Programs, better known as Skunk Works, Have Blue was developed at the top-secret Area 51 base near Rachel, Nevada. The Have Blue was the first fixed-wing aircraft designed from an electrical engineering perspective. The aircraft's plate-like, faceted shape was designed to deflect electromagnetic waves, greatly reducing its radar signature.
