![]() ![]() The Lun was powered with eight Kuznetsov NK-87 turbofans, mounted on forward canards, each producing 127.4 kN (28,600 lbf) of thrust. The Lun-class ekranoplan was developed on the basis of the experimental KM ekranoplan, which was nicknamed the " Caspian Sea Monster". Design and development Lun class at Kaspiysk, Russia, in 2010 Scale model of a Lun-class ekranoplan displayed in a museum The name Lun comes from the Russian word for the harrier. This effect does not occur at high altitude. The ground effect occurs when flying at an altitude of only a few metres above the ocean or ground drag is greatly reduced by the proximity of the ground preventing the formation of wingtip vortices, thus increasing the efficiency of the wing. Rather, craft like the Lun-class ekranoplan are classified as maritime ships by the International Maritime Organization due to their use of the ground effect, in which the craft glides just above the surface of the water. Although they might look similar to traditional aircraft, ekranoplans like the Lun are not classified as aircraft, seaplanes, hovercraft, or hydrofoils. It flew using lift generated by the ground effect acting on its large wings when within about four metres (13 ft) above the surface of the water. It was designed by Rostislav Alexeyev in 1975 and used by the Soviet and later Russian navies from 1987 until sometime in the late 1990s. The Lun-class ekranoplan ( Soviet classification: Project 903) is the only ground effect vehicle (GEV) to ever be operationally deployed as a warship, deploying in the Caspian Flotilla.
