The "Caspian Sea Monster" - the Ekranoplan KM - holds the distinction of being the largest Ground Effect vehicle ever built. The Sea Monster carried record payloads quickly and economically by riding just above the sea waves on a cushion of air, or "ground effect", which significantly increased lift and reduced drag.
-------- It is a monster over sea, also a potential vehicle in future.
I would like share some technologies with you~!
