Using a polyhedral airframe that eschewed right angles and curved surfaces to avoid radar detection, the Lampyridae completed several successful tethered test flights before the project was cancelled in 1987. Eerily similar to the then top-secret American F-117 Stealth Fighter, the Lampryridae was considered by many to actually have superior radar-avoidance properties even though it had only half the number of facets of its American counterpart.https://en.wikipedia.org/wiki/MBB_Lampyridae
