How many of you have heard about them?
Ekranoplan is a Russian word it means 'screen craft' or 'skimmer'. It is not a plane nor is it a ship, moreover its a mixture of both. The craft moves along on a dynamic cushion of air that is generated by its forward movement. It has similar characteristics of the common hovercraft in that it flies just above the surface as it moves. It will not however, hover while stationary but sit in the water.
These craft are big and fast and were kept secret from the west until the fall of communism in the early 1990's. It can quite easily be envisaged a hundred of such craft zooming across the ocean relatively undetected underneath radar to invade a country. And by the time that country reaslised what was going on it would have been too late.
Never underestimate the Russians, they are practical, innovative, resourceful and militaristically astute.
