| Citat: | 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.
The ships, better able to chase down pirates, have been fast-tracked because the Navy wants vessels that can operate in coastal, or littoral, waters. Freedom is due to be deployed next year, two years ahead of schedule.
Independence is an aluminum, tri-hulled warship built by Austal USA in Mobile, Ala. The lead contractor is Maine's Bath Iron Works, a subsidiary of General Dynamics.
Lockheed Martin Corp. is leading the team that built Freedom in Marinette, Wis. It looks more like a conventional warship, with a single hull made of steel.
The stakes are high for both teams. The Navy plans to select Lockheed Martin or General Dynamics, but not both, as the builder. The Navy has ordered one more ship from each of the teams before it chooses the final design. Eventually, the Navy wants to build up to 55 of them.
Speed has long been relished by Navy skippers. Capt. John Paul Jones, sometimes described as father of the U.S. Navy, summed it up this way in 1778: "I wish to have no connection with any ship that does not sail fast; for I intend to go in harm's way."
Eric Wertheim, author and editor of the U.S. Naval Institute's "Guide to Combat Fleets of the World," said speed is a good thing, but it comes at a cost.
"This is really something revolutionary," Wertheim said. "The question is how important and how expensive is this burst of speed?"
Early cost estimates for Littoral Combat Ships were about $220 million apiece, but costs spiraled because of the Navy's requirements and its desire to expedite construction. The cost of the ships is capped at $460 million apiece, starting in the new fiscal year.
Both ships are built to accommodate helicopters and mission "modules" for either anti-submarine missions, mine removal or traditional surface warfare. The goal is for the modules to be swapped out in 24 hours, and no later than 96 hours, allowing the ships to adapt quickly to new missions, said Cmdr. Victor Chen, a Navy spokesman.
While they're fast, they aren't necessarily the fastest military ships afloat. The Navy used to have missile-equipped hydrofoils and the Marines' air-cushioned landing craft is capable of similar speeds, Wertheim said. And smaller ships are capable of higher speeds.
Nonetheless, the speed is impressive, especially considering that other large naval vessels have been cruising along at a relatively pokey 30 to 35 knots for decades.
Loren Thompson, a defense analyst at the Lexington Institute, noted that Independence sustained 44 knots despite a 30-knot headwind and 6- to 8-foot seas in Alabama's Mobile Bay. "For a ship of this size, it's simply unheard of to sustain that rate of speed for four hours," he said. |

Potrudicu se da prevedem cim budem imao vremena.
Nego, vredi li ovo nesto, i cime bi uopste bio naoruzan?

Ukratko, kosta duplo vise od planiranog i jos prostije: preskupo. |

ufff,nisu normalni,za to bi kupio 5-6 gripena...to je prestrašno koliko ta mornarica košta,pa cak i da zemlja kao sto je HR kupi nesto takvo,nije problem samo kupiti jbg ga,upravo da to zelimo i slati van u misije,ko ce placati odrzavanja,gorivo etc etc...ali prokleto je dobro dizajniran sa ovim nosom onako dugim špičastim,više izgleda kao neki vojni katamaran,dizajniran je tako da ce sigurno imati dobre stealth karakteristike ,pogledaj mu samo povrsinu,kao da je pravljen iz istog materijala kao i raptor.

Super... da li Gripen može da se usidri u vazduhu 4300 nautičkih milja daleko od baze i da tamo izvršava zadatke?
Mogao si da prevedeš i u cenu pušaka, ispalo bi više.... Podsećaš me na pešadince koji nikako nisu mogli da uklavire da brod i FAP nisu isto i da im treba više nafte da bi ga tankirali... |

Nista cudno. Odavno je to tako kod njih. Ide se sa cenom koja nije moguca samo da bi kongres odobrio projekat. A onda cene polako ali sigurno rastu |

| Vidim imaju heliodrome, pa me zainteresovalo, da li brod mora da stane da bi helikopter sleteo, ili ima neki način sinhronizacije brzine? |

A zašto to nebi sami napravili imate dosta škverova sa radnicima koji nemaju što da rade.
Inaće su ti novi LCSovi bezobrazno brzi, 45 čvorova (oko 85 km/h) za tako veliki brod to nije više normalno ima da sve oduva što je bliže od 200 metara od broda kad kapitan ožeži po gasu. |
