US Navy Drops LCS Plans, Concept After Latest Failures

(Source: Defense-Aerospace.com; published Sept 9, 2016)
By Giovanni de Briganti

The US Navy has finally decided to abandon the unworkable Littoral Combat Ship modular concept, and to turn the ships it has on order into dedicated, single-mission vessels. Both LCS variants are shown here. (USN photo)
PARIS --- After spending billions of dollars, the US Navy has finally abandoned the Littoral Combat Ship concept, saying it will turn the first four LCSs into training ships and that all future vessels will be equipped for a single combat mission.

Although deliberately worded to minimize its import, the US Navy statement below is a clear acknowledgement that the LCS concept has been an abysmal failure.

But, even as it looks to mitigate the disastrous effects of having ordered a dozen LCS at once, before checking whether they performed as claimed (they have not), the Navy makes no mention of having found the technical faults which have struck four LCS ships this year.

In the statement below, the Navy announces it is abandoning the LCS’ most prized objectives (interchangeable mission modules; innovative but complex crewing arrangements) which were supposed to turn inexpensive small ships with small crews into potent combatants in coastal regions.

Ironically, this is an admission that the Government Accountability Office was right in recommending, in its latest report on the LCS program issued in June, that “Congress should consider not funding any requested LCS in fiscal year 2017 and should consider requiring the Navy to revise its acquisition strategy for the frigate.”

In fact, the ships are very expensive ($562.8 million for each ship, according to the Congressional Research Service. This is about as much as a DDG 51 destroyer, whose last batch cost about $700m each), their small crews are unable to switch mission modules even when these are available, and their crewing arrangements have proved inoperative.

By turning the four Littoral Combat Ships it has commissioned to date into training ships, the Navy is also admitting they are operationally worthless.

So the LCS concept is a total failure, and the billions of dollars spent so far have been wasted, despite each one having cost about half a billion dollars.

All of this should be of major concern as the US Navy has ordered 22 ships under two block buy contracts awarded to the two LCS builders in December 2010, and the 8th was delivered in mid-August. These contracts run until FY2022.

This means the Navy is still buying fault-plagued ships designed to a failed operational concept at over a half-billion dollars a pop, which is neither a good idea nor a prudent use of taxpayers’ billions of dollars.

Whether, or how, the US Navy reacts to the LCS ballooning problems in the acquisition field will determine how seriously its military and civilian chiefs take their responsibilities.

Navy Adjusts LCS Class Crewing, Readiness, and Employment

(Source: U.S Navy; issued Sept 8, 2016)

SAN DIEGO --- The Navy announced today it will implement several key changes to the projected 28-ship Littoral Combat Ship (LCS) Flight 0/0+ class over the next five years that will simplify crewing, stabilize testing, and increase overseas deployment presence availability.

The projected 12 Frigates will be the next increment of LCS and will use the same manning, training, maintenance and operating concepts as those that have been approved as part of the LCS review.

The decision to make these changes resulted from a comprehensive review of LCS crewing, training, maintenance, and operations commissioned in March.

While a total of 40 ships have been approved for the program, the Navy Force Structure Assessment still projects the need for 52 small surface combatants that LCS and Frigate address.

Beginning this fall, the Navy will start to phase out the 3:2:1 crewing construct and transition to a Blue/Gold model similar to the one used in crewing Ballistic Missile submarines, patrol craft and minesweepers. The LCS crews will also merge, train, and rotate with mission module detachment crews, organizing as four-ship divisions of a single warfare area - either surface warfare (SUW), mine warfare (MCM), or anti-submarine warfare (ASW).

Though organized this way, the LCS class will retain the technological benefits of modularity and the ability to swap mission packages quickly if needed. Aviation detachments will also deploy with the same LCS crew, but will remain assigned to their respective squadrons when in home port.

To facilitate these changes across the class, the Navy will eventually homeport Independence-variant ships in San Diego and Freedom-variant ships in Mayport, Fla. 24 of the 28 LCS ships will form into six divisions with three divisions on each coast. Each division will have a single warfare focus and the crews and mission module detachments will be fused.

Each division will consist of three Blue/Gold-crewed ships that deploy overseas and one single-crewed training ship. Under this construct, each division's training ship will remain available locally to certify crews preparing to deploy. Few homeport shifts will be needed since only six LCS are currently commissioned while the rest are under contract, in construction, or in a pre-commissioned unit status.

The first four LCS ships (LCS 1-4) will become testing ships.

Like the training ships, testing ships will be single-crewed and could be deployed as fleet assets if needed on a limited basis; however, their primary purpose will be to satisfy near and long term testing requirements for the entire LCS class without affecting ongoing deployment rotations. This approach accommodates spiral development and rapid deployment of emerging weapons and delivery systems to the fleet without disrupting operational schedules.

Implementing these changes now and as more LCS ships are commissioned over the coming years will ultimately allow the Navy to deploy more ships, increasing overall forward presence. With the Blue/Gold model in place, three out of four ships will be available for deployment compared with one out of two under 3:2:1. The Blue/Gold model will also simplify ownership of maintenance responsibilities and enhance continuity as the same two crews rotate on a single ship. Single-crewed training ships will complement shore-based training facilities and ensure crews have enough time at sea before deployment. The findings and recommendations of the LCS review will allow the LCS program to become more survivable, lethal, and adaptable as the LCS become regular workhorses in the fleet.

"As we implement these changes, we will continue to make iterative adjustments and improvements based on evolving fleet requirements and technological developments," said Vice Adm. Tom Rowden, commander, Naval Surface Forces. "Implementing the approved recommendations from this review and continuing to examine other areas for improvement will better position the LCS program for success - both now and in the future."

Watch Navy shock testing from the deck of a new LCS
Batten down the hatches.

Brandon Turkus

http://www.youtube.com/watch?v=vpYyhrjeup8
This post is appearing on Autoblog Military, Autoblog's sub-site dedicated to the vehicles, aircraft, and ships of the world's armed forces.

Shock testing is a major milestone for any US Navy warship. But while setting off increasingly large charges at increasingly close distances with a live crew onboard sounds scary enough, seeing it from the ship's deck gives a far more visceral understanding of what new ships and their crews go through.

This is USS Jackson, a Navy Littoral Combat Ship we've talked about before. But while we've told about how the Navy is trying to blow up one of its newest ships, all we had at the time was a photo of the Independence-class ship's first test. This video shows those tests in high-definition and from multiple angles. Unfortunately, the music selection is bad, but you can still get an idea of the rigors a new ship like the Jackson endures during the trials. Just watch the way components like the CIWS cannon shakes following an impact.

Check out the video, available up top.

Newest US aircraft carrier to miss another delivery deadline

Imagem

The most expensive ship the U.S. Navy has ever built is once again bound to miss a delivery deadline.

USS Gerald R. Ford, the lead ship of a next generation of U.S. aircraft carriers, was scheduled to be delivered to the Navy in 2014, but the deadline kept being pushed back.

The latest delivery was scheduled for November this year, but according to a report by the Virginian Pilot, the delivery was delayed again and the Navy did not set a new one.

Defense News reported in September this year that voltage regulator problems on the carrier’s four main turbine generators (MTGs) resulted in an electrical explosion in one of the turbines in June with another, smaller, explosion taking place in July.

“We continue to look for opportunities to get Gerald R. Ford to sea as soon as possible. The Navy is evaluating the most cost-effective and efficient schedule to complete sea trials and ship delivery,” Navy spokesman Capt. Thurraya Kent was quoted as saying by the Virginian Pilot.

Earlier delays were caused by the carrier’s advanced arresting gear system which was, according to Senator John McCain $600 million over budget. Back in 2015, Ford faced a potential two-year delay which could have been caused by shock trial tests which were requested by Michael Gilmore, Director, Operational Test and Evaluation.

With a price tag of $12.9 billion, USS Gerald R. Ford is the most expensive ship in the Navy’s fleet. The $10.5 billion estimate from 2007 rose by 23 percent.

Gerald R. Ford (CVN 78) was ordered from Newport News Shipbuilding, a subsidiary of Huntington Ingalls Industries, on Sept. 10, 2008. With this new class of ships the U.S. Navy hoped to save $4 billion in total ownership costs during each ship’s 50-year service life, compared to the Nimitz-class.

The 1,100 foot (335 meter) ship displaces 100,000 tonnes and is designed to operate effectively with nearly 700 fewer crew members than a CVN 68-class ship. Improvements in the ship design will, according to the Navy, allow the embarked air wing to operate with approximately 400 fewer personnel.

É como eu sempre digo. Esta história de sair encomendando um monte de navios antes de se comprovar que a primeira unidade entrega realmente o que se espera dela é um risco enorme, e nem mesmo a toda poderosa e avançadíssima USN pode evitar que isso se torne um pesadelo.

Marinhas não se improvisam.

E pra contrariar o lobby?

Se bobear as empresas devem praticamente impor os projetos para as F.A. dos EUA.

Tem muito disso mesmo. E a desculpa é uma suposta redução dos custos, que na prática jamais se materializa.

Mas me parece evidente que este não é exatamente um exemplo a ser seguido.
