Khinh tốc đỉnh tàng hình mới nhất của Mỹ , tốc độ 97 km giờ , dùng kỹ thuật lướt sóng mới gọi là " Lỗ to " ( "supercavitation" ). Để di chuyển cực cao , phần chìm dưới nước của thân tầu , sẽ phát ra một luồng hơi ngăn nước với thân tầu , như thế thân tầu lướt sóng , tránh được sức cản của nước .

Với tốc độ cao và radar không thấy , Khinh tốc đỉnh tàng hình chủ yếu dùng vào việc mang Thuỷ lôi ( torpedoes ) để bắn phá chiến hạm lớn của đối phương .[/COLOR]

Meet the 'Ghost' - the stealth ship radar can't see

A US company has built a high-speed stealth "attack helicopter on the water" that could revolutionise navies and the shipping industry.

The ship, called The Ghost, can glide on water using a layer of gas that is generated around its submerged areas at high speeds - a technology called "supercavitation", designer Juliet Marine Systems said.

The Ghost can reach speeds of up to 97km/h, would be undetectable by radar and could be used by the US Navy to carry torpedoes, the company said.

It could also protect larger ships, both military and commercial, from pirate and terrorist attacks, chief executive of Juliet Marine Gregory Sancoff told the Discovery Channel.

"Right now we have thousands of sailors whose only defence against high-speed craft is a .50 calibre machine gun from World War II," Mr Sancoff said.

Defence expert Sam Roggeveen from the Lowy Institute's Interpreter blog said there was a market for small high-speed crafts such as The Ghost, with Australian catamaran companies already supplying combat and transport ships to the US Navy.

"The US Navy wants something between airlifting and traditional sealifts. Airlift is very fast but very expensive ... with very small amounts of equipment moved at a time. Sealifts are much cheaper but extremely slow."

He said the Australian Navy leased a catamaran during the East Timor crisis.

China was one country that has invested in high-speed attack craft and its navy had dozens of missile-armed catamarans based on an Australian design, he said.

But he said military bureaucracies tended to be very conservative when it came to purchasing new equipment, especially if it involved "exotic technology".

"Although I understand the Russians have been working on supercavitation for some time, this is still fairly immature technology," Mr Roggeveen said.

"It can take years and sometimes decades for these things to fully mature, and for military forces and defence ministries to have the kind of confidence that they place orders for these vessels."
