The device its selfEdit
A Ekranoplan would also be used in the Soviet invasion of Denmark if they had lived up to expectorations. A hand full of prototypes were made and tested. A planned civil cargo variant was partly built, but never tried out. The civil passenger and military utility versions never got off the drawing board.
Boeing tried a joint venture with the Russians in mid 1990s, but if was unsuccessfully due to political, not corporate issues. American, Ukrainian (until Russia invaded the Dombass region), Chinese, Japanese and Russian firms are trying out various small prototypes for high speed civil use.
