The Lun-class ekranoplan was a ground effect aircraft designed by Rostislav Evgenievich Alexeev and used by the Soviet and Russian navies from 1987 to sometime in the late 1990s.
It flew using the extra lift generated by the effect of its large wings when close to the surface of the water – about four metres or less. Lun was one of the largest seaplanes ever built, with a length of 73 m, rivalling the Hughes H-4 Hercules (“The Spruce Goose”) and many jumbo jets.
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 aircraft of this type ever built, the MD-160, entered service with the Black Sea Fleet in 1987. It became retired in the late 1990s and is now sitting unused at a naval station in Kaspiysk.
