The ''Lun''-class ekranoplan (NATO reporting name ''Duck'') is a ground effect vehicle (GEV) designed by Rostislav Evgenievich Alexeyev and used by the Soviet and Russian navies from 1987 until sometime in the late 1990s.〔 It flew using the lift generated by the ground effect of its large wings when close to the surface of the water–about or less. Although they might look similar and have related technical characteristics, ekranoplans like the Lun are not aircraft, seaplanes, hovercraft, nor hydrofoils–ground effect is a separate technology altogether. The International Maritime Organization classifies these vehicles as maritime ships. The name ''Lun'' comes from the Russian for harrier. ==Design and development== The Lun was powered with eight Kuznetsov NK-87 turbofans, mounted on forward canards, each producing of thrust. It had a flying boat hull with a large deflecting plate at the bottom to provide a "step" for takeoff.〔 It had a maximum cruising speed of .〔 Equipped for anti-surface warfare, it carried the P-270 ''Moskit'' (Mosquito) guided missile. Six missile launchers were mounted in pairs on the dorsal surface of its fuselage with advanced tracking systems mounted in its nose and tail. The only model of this class ever built, the ''MD-160'', entered service with the Black Sea Fleet in 1987. It was retired in the late 1990s and is now sitting unused at a naval station in Kaspiysk.〔 Another version of ''Lun'' was planned for use as a mobile field hospital for rapid deployment to any ocean or coastal location. It was named the ''Spasatel'' ("Rescuer"). Work was about 90% done, when the military funding ended, and it was never completed.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lun-class ekranoplan」の詳細全文を読む スポンサード リンク
