Invisibility on the cradle

The ability to create a bottom layer and special design allows one type of ship in the United States to move extremely fast and avoid detection of radar.

Discovery reports that Juliet Marine, a New Hampshire-based company in the US, has successfully built a type of vessel capable of producing a bottom layer of air. Thanks to the gasket the vessel can reach speeds of up to 96 km / h and the friction between the ship and the water surface is reduced to 900 times that of regular ships. The design team made the ship a special shape so that it could avoid radar detection. The ship was named Ghos t (meaning "ma" in English).

Gregory Sancoff, president and chief executive officer of Juliet Marine, explains that when a subject moves fast on the water surface, it is capable of producing a low pressure area at the bottom. If the speed reaches a certain level, the low pressure zone changes into a gas cushion. Sancoff claims that Ghost is like a Russian torpedo.

In principle, to turn ships and planes into objects capable of escaping radar detection, people must find ways in which radar waves do not return to the transmitter after they have hit the crust.

Jan Brink, an electroencephalographer at Swedish company Kockums, says that because of its water activity, ships primarily deal with radar from above, while aircraft deal with radar from below.

"The radar that ships receive may come from other ships or missiles ," Brink said. He refuses to reveal more about Ghost's stealth technology.

Ghosts are designed to operate near the coast - such as bringing troops into the mainland or picking them up from the mainland to the sea. It can also be used to combat piracy and escort carriers as well as frigates. In fact, carriers and destroyers are very vulnerable to the attack of small groups of ships and move at high speed. The presence of Ghost will help them mitigate that risk.
