BATH, Maine – The Navy's need for speed is being answered by a pair of warships that have reached freeway speeds during testing at sea.Independence, a 418-foot warship built in Alabama, boasts a top speed in excess of 45 knots, or about 52 mph, and sustained 44 knots for four hours during builder trials that wrapped up this month off the Gulf Coast. The 378-foot Freedom, a ship built in Wisconsin by a competing defense contractor, has put up similar numbers.
Both versions of the Littoral Combat Ship use powerful diesel engines, as well as gas turbines for extra speed. They use steerable waterjets instead of propellers and rudders and have shallower drafts than conventional warships, letting them zoom close to shore.
I have real problems with that new greyhound of yours, it might be fast, it might look the part. But it's a "one hit ship".

They're supremely confident their systems can stop any weapon from getting through their defensive nets. Does it always work? Not in the case of the USS Cole, which was nearly sunk by the Iraqi in the 1980's. But since then newer Aegis systems track all threats not to just their own ships but to all the ships in their group, allowing them to work as a unified system to stop incoming threats. AFAIK all modern Navy ships have eliminated armor in their hull designs.

They have been going 50 knots for awhile, top speeds are always classified.
How fast do you think the USS Enterprise goes with 8 (yes that is 8) reactors when all others have only 2..

Not that I can confirm anything about the origin of the first water jet
When he took one of his early demonstration jet boats to the US, the media scoffed when he said he planned to take it up the Colorado River (U.S.), but in 1960 a Hamilton jet became the first boat to travel up through the Grand Canyon. The critics were silenced further when the boat also went down river through the canyon.
Jetsprinting as an organised sport originated in New Zealand in 1981, and events were originally held in the same natural braided rivers that had inspired Sir William Hamilton to develop the jetboat, but when the sport was introduced to Australia in the mid-1980s permanent artificial courses were used—and this is now the norm even in New Zealand.
