Say what you will about the LCS, and I agree with a lot of them, over priced, behind schedule, under-armed for their displacement, and under-crewed, but when you stomp the throttle, they go like a scorched cat:

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.

I have no clue as to their endurance when going this fast, but my guess is that they would need to refuel if they wanted to cross the Pacific at this speed.
