Video Lun class Ekranoplan (Caspian)

The Lun-class ekranoplan (NATO reporting name Duck) was a ground effect vehicle (GEV) designed by Rostislav Evgenievich Alexeev 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 four metres or less. Although they might look similar and have related technical characteristics, ekranoplans like the Lun are not aircraft, seaplanes, hovercraft, or hydrofoils
