Ground effect vehicle

The Russian Lun-class ekranoplan during a test run on the Caspian Sea.

A ground effect vehicle (GEV) is a vehicle that is designed to attain sustained flight over a level surface (usually over the sea), by making use of ground effect, the aerodynamic interaction between the wings and the surface. Among the best known are the Soviet ekranoplans, but names like wing-in-ground-effect (WIG), flarecraft, sea skimmer, or wing-in-surface-effect ship (WISE) are also used.
