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 4 metres (13 ft) 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.
The Lun was powered with eight Kuznetsov NK-87 turbofans, mounted on forward canards, each producing 127.4 kN (28,600 lbf) 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 340 miles per hour (550 km/h).
