After Delays, LCS 2 Completes Builder's Trials

By philip ewing - 21 Oct 2009 16:34

The Navy's second littoral combat ship, the Independence, finished its builder's trials Wednesday, more than three months after first sailing from its Mobile, Ala., shipyard for its tests at sea.

The aluminum trimaran hit a top speed of 45 knots and kept a sustained speed of 44 knots during its full power run in the Gulf of Mexico, shipbuilder General Dynamics said in an announcement. It kept a high speed and stability despite eight-foot waves and 25-knot winds.

[...]

Navy officials will decide next spring which version of LCS they will put into full-scale production.

That decision will take place during or after the Freedom's trial deployment, scheduled for early 2010, in which the ship will take a test mission to South America and the Pacific with its surface warfare mission module. But the down-select will take place before the Independence can do its own trial deployment, although Navy officials say they don't need to see its performance on a test mission to decide which LCS they'll buy.

Each LCS was initially pitched to Congress for a cost of about $220 million, but according to the Navy's latest budget figures, the Freedom has cost $637 million and the Independence has cost $704 million. The Navy has awarded contracts for a second Freedom-class ship - the Fort Worth - and a second Independence - the Coronado - but has not disclosed the value of the contracts. ...

US NAvy Littoral Combat Ship Earns High Marks on Maiden Voyage

US NAVY said:

WASHINGTON, March 22, 2010 – A month into a maiden voyage that has seen a trio of drug-smuggling attempts thwarted, the commander aboard the Navy’s first littoral combat ship today described the vessel’s performance to date as “exceptional.”

Now floating off the coast of Colombia, the USS Freedom received high marks from Navy Cmdr. Randy Gardner, who delivered an assessment to reporters today from aboard the ship via telephone.

“The performance of the ship so far has been exceptional,” he said of the Freedom, which set sail Feb. 16 from Mayport, Fla. “We are learning a lot about what Freedom can do well.”

Freedom and its crew grabbed headlines in recent weeks after interdicting three vessels transporting illicit drugs through the western Caribbean. Military officials say the ship’s speed, which at roughly 46 miles per hour is significantly faster than U.S. frigates that max out just below 30 miles per hour, is responsible for much of its counternarcotics success.

In its most recent interdiction, the Freedom disrupted a high-speed ship known as a “go-fast” vessel and recovered more than 2 tons of cocaine that officials said was bound for the United States.

After detecting the suspected drug vessel March 11, the Freedom launched a high-speed pursuit and deployed a separate team of sailors and Coast Guardsmen aboard rigid inflatable boats to intercept it. Smugglers aboard the fleeing vessel began dumping its cargo into the southern Caribbean Sea.

The Navy-Coast Guard response team recovered 72 bales of cocaine weighing a total of 4,680 pounds from the water after being jettisoned from the vessel that was on a “stereotypical route” pursued by drug traffickers with U.S.-bound narcotics, Gardner said.

During its first two successful drug seizures in the Caribbean -- on Feb. 22 and March 3 -- Freedom seized one “go-fast” vessel, five suspects and more than 3,700 pounds of cocaine.

In addition to counternarcotics operations, the Freedom made its first shore leave in Cartagena, Colombia, Gardner said. The Freedom also played host to top defense officials from Colombia who toured the ship while it was docked in Cartagena.

The Freedom, which is deploying about two and a half years before the first littoral combat ship was expected to be operational, is bound for Panama and Mexico before it’s set to return to its home port in San Diego in late April. After undergoing about a month of routine maintenance, the ship then will carry out operations in Canada, followed by an exercise in the Pacific Ocean, military officials said.

The Freedom, along with the USS Independence, is at the vanguard of a Navy littoral combat ship fleet that is expected to grow to about 55 vessels by 2035, officials said.

Found a nice & interesting article on defensenews comparing the two LCS designs briefly in 12 areas.

LCS 1 Vs. 2: Both Meet the Requirements, But Similarities End There

By CHRISTOPHER P. CAVAS - Published: 3 May 2010 15:00

The two ships vying to become the prototype for a new U.S. Navy fleet of Littoral Combat Ships (LCS) have, according to top Navy officials, virtually the same combat capability. "Both ships meet the requirements" has been a mantra for officials testifying to Congress and speaking to the media.

But the Lockheed Martin and General Dynamics teams have fielded ships that take very different approaches to fulfilling the basic LCS requirements for a fast, smallish ship able to provide basic combatant services while taking on specialized equipment to carry out focused missions. ...

Is it likely for a revised design incorporating elements of both LCS prototypes as the main production unit?

This means at least 24 LCS (Up to 12 of each class) of LCS have either been built (3 do far) or are under contract to build.

That's interesting.

Wasn't there supposed to be only 1 class selected to minimise costs and maximise economies of scale? I suppose in the trials, the USN found both classes to be useful?

Re: Littoral Combat Ships (LCS); Which is best?

That whole LCS thing is a really long back and forth story. I think the Navy lobbied pretty hard to finally be allowed by congress to accuire both types. Probably to avoid painfull, lengthy and costly protests and rebids. So they'll get two types.
And the programm was somehow brought back on the cost schedule. I think one hull is down to 300 and something million from the once estimated 450+ per ship. That would be a good sign for the industry and navy acquisition programs.
On the other hand, critics pretend these ships are just really fast patrol boats instead of warships, hence actually still expensive for what they offer. The navy will not do the normal blast shock tests it does with all the other hulls, becuse several components of the ship may sustain unrecoverable damage. Apparently they are built to civil structural standarts, and not military?

No, not really. As both ships are operated the US Navy is discovering both ships have unique virtues and unique vices. The decision to down select is not so simple as both offer capabilities the US Navy very much needs.

LCS 1 is based on a civilian hull form from Fincantiere. It was originally built to a more or less civilian spec but the inspectors at NAVSEA had a lot of heartburn with that and made them redesign and re-equip it to the normal US Navy specification for it's combat ships.

The Navy had to cancel the third and fourth prototypes to get their attention and really beat both contractors over the head to get the program back on budget. The Navy more than the other services is taking cost management very seriously. The Navy even threatened to consider a version of the National Security Cutter outfitted for the LCS mission to get the contractors in question to behave.

Re: Littoral Combat Ships (LCS); Which is best?

The reason de etre for the LCS is the inability of fast attack craft to sustain open ocean voyages with our larger surface combatants. Frigates like the oft mentioned Fremm and other traditional displacement hull combat craft of sufficient size to cross oceans comfortably in all weather are too slow and draw too much water to go inshore and mix with enemy fast attack craft on equal terms. The USN tried a number of patrol craft designs, from the PGH's of the 1970's through various hydrofoil designs and found that all were much too small for long deployments with a CSG or ARG. They needed to fuel every day, could not make their own fresh water, needed laundry services and other services from the carrier, and in general were too slow in a big swell in the middle of the ocean. Their crews suffered and they slowed the rest of the ships down.
What to do? For decades now we relied on SH-60's shooting Penguins and later Hellfire to perform the mission for us. The LCS is supposed to be a fully seaworthy ship that can cross the ocean with the carrier or the LHD, yet possess the speed and shallow draft necessary to go close inshore and mix with enemy fast attack craft, and defeat them. Frigates cannot do this mission.

Deleted, Ambivalent clarified the LCS's purpose.

I notice the LCS lacks any anti-submarine or anti-ship missiles, saving that room and weight for more hanger space and resources for a longer voyage.
