MD-160, Lun-class Ekranoplan

It flew using the extra lift generated by the effect of its large wings when close to the surface of the water - about four meters or less. Lun was one of the largest seaplanes ever built, with a length of 73 m (240 ft), rivaling the Hughes H-4 Hercules ("The Spruce Goose") and many jumbo jets. The name Lun comes from the Russian for harrier.

The only aircraft of this type ever built, the MD-160, entered service with the Black Sea Fleet in 1987. Eight Kuznetsov NK-87 turbofans were mounted on forward canards, and each produced 127.4 kN (28,600 lbf) thrust. It had a flying boat hull with a large deflecting plate at the bottom to provide a "step" for takeoff.

The aircraft was equipped for anti-surface warfare, and it carried the P-270 Moskit (Mosquito) guided missile. It was equipped with six missile launchers, mounted in pairs on the dorsal surface of its fuselage, and its advanced tracking systems mounted in its nose and tail.

Another version of Lun was planned for use as a mobile field hospital for rapid deployment to any ocean or coastal location. Work was about 90% complete on this model, the Spasatel, but its military funding ended, and it was never completed. The only MD-160 completed is now sitting unused at a naval station in the town of Kaspiysk.

In 2007, the Ministry of Defence of the Russian Federation decided to resume production of this model of ekranoplan in 2012, following a detailed examination of the unit. Until then upgrades would be made to the craft. At present, the relevant government order has been received by the Alexeyev Design Bureau.
