funding ran out for this ground effects cruise missle carrying seaplane

this aircraft used the ground effect – extra lift of large wings when close to the waters surface, a maximum of three meters above the sea but at the same time could provide take off, stable “flight” and safe “landing” in conditions of up to 5-meter waves. These were originally developed by the Soviet Union as high-speed military transports, and were based mostly on the shores of the Caspian Sea and Black Sea.
