Lun-class ekranoplan
https://en.wikipedia.org/wiki/Lun-class_ekranoplan
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.[1][2]
It flew using the lift generated by the ground effect of its large wings when
might look similar and have related technical characteristics, ekranoplans like
a separate technology altogether. The International Maritime Organization
classifies these vehicles as maritime ships
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.[4] It had a maximum cruising speed of 340 miles per hour (550 km/h).[2]
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.[5]
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.[2][6][7]
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.
