Evo jedne malo duže priče.
Ena cvetka
Citat:Naval analyst Raymond Pritchett has pithily described the current compromise as:
”...3000 ton speedboat chasers with the endurance of a Swedish corvette, the weapon payload of a German logistics ship, and the cargo hold of a small North Korean arms smuggler.”


Citat:So, too, has the use of aluminum in ships exposed to hostile fire. The LCS-1 Freedom Class uses an aluminum superstructure, while the LCS-2 Independence Class is primarily an aluminum design. While both ships have had to certify to the same fire-proofing standards asked of other ships, aluminum conducts heat very well, and melts or deforms easily.
Otpornost nije jaka strana
Citat:June 17/11: The US Navy has told Congressional appropriations committees that “aggressive” corrosion was found in the propulsion areas of USS Independence, which rely on Wartsila waterjets. The ship has been given temporary repairs, but permanent repairs will require dry-docking and removal of the water-jet propulsion system. The strong Australian dollar has hurt Austal’s commercial exports, so this blow to its defense business has added impetus.
Opet cena gore... Zagrljaj

Sigurno je popločan iznutra nekim oklopnim panelima koji su još i izolaciono sredstvo. Što se tiće aluminija topi se već kod 700°C i vrlo je zapaljiv ako ga uspoređujemo sa ćelikom. No nema druge (osim kompozita) ako se hoće postići laganost broda i time sposobnost za velike brzine.

Nije sve tako sivo
June 20-22/11: After USS Independence [LCS-2] corrosion reports hit Austal’s share price, a company release addresses the issue. It notes the complete lack of such problems on all of Austal’s commercial and military ships to date, and suggests that the US Navy may have failed to follow basic procedures. Information Dissemination has a different take, and wonders if Austal’s JHSV, which may not have a cathodic protection system either, could also be at risk due to the military’s added electronics:

“In the case of LCS-2, the problem was apparently accelerated by stray currents in the hull from the electrical distribution system problems the ship has been having since it was turned over to the Navy. LCS-4 doesn’t have [a cathodic protection system] either, but apparently CPS is part of the lessons learned process and was included in the fixed-price contracts for Austal versions of the LCS beginning with LCS-6. LCS-2 will have the CPS installed at the next drydock period, while Austal has said a CPS will be added to LCS-4 before the ship is turned over to the Navy. The question everyone seems to be asking is whether the JHSV could suffer the same issue…. I’d be curious to know if Westpac Express has a CPS installed, or some other form of prevention is used at all.”

Zahtjev za brzinom i malom posadom ovaj brod je zakomplicirao do daske i na kraju i nije nešto upotrebljiv. I još činjenica, da mora ovaj brod služiti kao lovac mina.

Daleko bolja rešenja u ovoj klasi su brodovi Absalon ili njemački Meko.

Mornarici isporucen treci LCS-USS Fort Worth (LCS 3) i to pre roka.

Citat:Fort Worth is the third littoral combat ship (LCS) delivered to the Navy, and the second LCS of the steel, semi-planing monohull Freedom variant.

Citat:The Lockheed Martin-led industry team delivered the nation's third Littoral Combat Ship, Fort Worth (LCS 3), to the U.S. Navy two months ahead of schedule.

LCS: Quick Swap Concept Dead
Arrow http://www.defensenews.com/article/20120714/DEFREG.....dyssey=tab|topnews|text|FRONTPAGE
Citat:The original idea for the littoral combat ship (LCS) envisioned modular mission packages that could be rapidly swapped, but instead of taking just days to make the switch, it’s now apparent it could take weeks. An LCS assigned to a particular operation will likely operate in a single “come-as-you-are” configuration, requiring additional ships equipped with other mission modules to provide the flexibility the concept once promised.
Podbaćaj br. 1 (nova stvar)
Citat:Planners originally envisaged the LCS as a replacement for the fleet’s frigates, minesweepers and patrol boats, but the new assessments conclude the ships are not equal to today’s frigates or mine countermeasures ships, and they are too large to operate as patrol boats.
Podbaćaj br. 2 O tome je već bilo...
Citat:But the LCS vessels cannot successfully perform three other core missions envisioned for them — forward presence, sea control or power projection missions — and they can provide only limited humanitarian assistance or disaster relief operations, sources said.
Rezultat podbaćaja br. 2
Citat:A key LCS failure identified by the OPNAV report, sources said, is its inability to effectively defend against anti-ship cruise missiles (ASCMs), a weapon carried by hundreds of small, fast-attack craft operated by virtually all potentially hostile navies. These weapons include C-801 and C-802 Chinese missiles, Russian SS-N-2 Styx missiles, European weapons such as the Otomat and Exocet, and U.S.-made Harpoon missiles.

Maintenance Hurdles Mount for New USN Ship
Arrow http://www.defensenews.com/article/20120723/DEFREG.....dyssey=tab|topnews|text|FRONTPAGE
Citat:The OPNAV report, according to sources, concluded that, in light of what the ships can and can’t do, the entire LCS concept of operations needs to be reviewed, along with the minimal-manning requirements and the contractor-based maintenance schemes.

O kada sam poćeo da pratim o ovom brodu nikako nisam mogao da shvatim šta će im. A ovo sada. Kako da se održava?...Ovo će biti razpoloživost ovako pola pola...

E sad ga malo i oni tupe koji brod može da se odbrani protiv više manjih čamaca koji nose protivbrodske rakete. U suštini u celom tekstu se kaže da još nisu prevazišli dečje bolesti. Ako sam dobro razumeo imaju problema i sa nedostatkom ljudstva u mornarici.
