In the early 1980s the German aerospace company Messerschmitt-Bolkow-Blohm (MBB) developed a design for a "stealth", medium range missile fighter named Lampyridae (Firefly). The external shape was composed of a number of triangular facets to reduce the radar cross section (RCS), particularly over the frontal arc that would be exposed to the radar of enemy fighters, much like the "Have Blue" and F-117.
The design was revealed to the US in 1987 when a group of USAF officers were shown the piloted model, kept in a closed-off section of MBB's plant at Ottobrunn in Bavaria. Reputedly, later calculations indicated the Lampyridae would have had a lower RCS than the famous Lockheed aircraft.
