Lockheed Have Blue

Lockheed Martin · United States · first flew 1977 · fighter

The Lockheed Have Blue was a secret technology demonstrator built to validate the principles of low-observable (stealth) flight, using radical faceted geometry to scatter radar returns. Two aircraft were built and flown under deep secrecy at Area 51.

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Unmistakable for its all-faceted fuselage, deeply swept delta wing, V-tail inward-canted surfaces, and complete absence of any rounded surfaces; far smaller and more angular than the production F-117.

History

Flown from 1977 to 1979 under the DARPA-funded Have Blue programme, the aircraft proved that a highly faceted shape could dramatically reduce radar cross-section. Both prototypes were lost in accidents but the programme directly led to the F-117 Nighthawk.

Variants

Two Have Blue prototypes (HB1001 and HB1002) were built; there were no production variants, the design evolving into the F-117.

Where you'll see it

The Have Blue never entered operational service; it was a pure technology demonstrator flown at classified test facilities in Nevada.
