We need twelve of her. A couple for each fleet and extras. Always that darn fiscal issue. LOL
She'll be even more potent when fitted with rail guns in the near future!
 
USS Michael Monsoor, DDG-1001, construction coming right along. She will be launched within the year.

...about the time the Zumwalt goes to sea. ...
Jeff, hope you're right, as
Delays in Zumwalt Destroyer Program Hamper Production of DDG-51s at Bath Iron Works
Delays in the construction of the first two of three next-generation Zumwalt-class (DDG-1000) guided missile destroyers at the General Dynamics Bath Iron Works shipyard are partially to blame for slowing work on two Arleigh Burke (DDG-51) destroyers being built at the Maine yard, USNI News has learned.

Several sources told USNI News that due to myriad reasons — including the size of the yard, the composition of the workforce at BIW and continued setbacks in the delivery of the first two next-generation Zumwalts — production of the future Burkes Rafael Peralta (DDG-115) and Thomas Hudner (DDG-116) have been delayed by several months.

USNI News understands the delivery schedule of Peralta has been pushed back seven months, while Hudner has been delayed five.

It’s unclear exactly how much the $22.1 billion Zumwalt program production is responsible for the delays in building the two Arleigh Burke ships, but several sources pointed to an electrician shortage on the yard as a major bottleneck. The three Zumwalts are being built with a revolutionary new integrated power system (IPS) for which the Navy is undertaking a rigorous testing program alongside its installation.

Neither the Navy nor BIW specifically addressed the Burke delays at the Maine yard when contacted by USNI News.

However, both issued statements to USNI News that pledged a commitment to increased efficiency in the construction of both the DDG-1000 and DDG-51 lines.

As of Tuesday, Zumwalt was “approximately 96 percent complete with her production and testing in support of delivery by Bath Iron Works,” the Navy said, adding the ship would begin pier-side trials in November and get under way in December. “Schedules for follow ships of the Zumwalt-class—Michael Monsoor (DDG-1001) and Lyndon B. Johnson (DDG-1002)—are likewise under evaluation.”

According to a Navy estimate in January, Johnson was 28 percent complete.

News of the bottleneck in Burke production comes at a bad time for the yard, as management is scrambling to improve overall efficiency for future destroyer work and a bid for a 25-ship, $10.5 billion contract for the U.S. Coast Guard’s new class of Offshore Patrol Cutters.

BIW’S Rising Costs
The two ships — Peralta and Hudner — were part of the Navy’s restart of the DDG-51 line announced in 2009 by then-Secretary of Defense Bob Gates following the cancellation of the service’s proposed next-generation cruiser (CG(X)) and the truncation of the DDG-1000 line to three ships.

In a series of deals between the Navy, BIW and its DDG-51 rival, Huntington Ingalls Industries (HII) Ingalls shipyard in Pascagoula, Miss., Bath was given the task of building the Zumwalt class following the reduction in the line.

“The agreement to have all three DDG-1000s built at BIW was a condition that Secretary of Defense Robert Gates set forth in an April 6, 2009, news conference on the FY2010 defense budget for his support for continuing with the construction of all three DDG-1000s (rather than proposing the cancellation of the second and third),”

While long-lead production work for the Zumwalts began at BIW, the yard won the contracts for the pair of Arleigh Burkes in 2011 when the yard

in a split competition for the three Burke restarts. BIW offered a price-per-hull of $679.6 million versus a bid of $697.6 million from the Pascagoula yard.

Two years later, when the Navy awarded a $6.1 billion multi-year shipbuilding deal for nine Burkes,

Not only did HII come in with the lowest bid per hull for the June 2013 award – $666.2 million per hull for five ships – BIW’s costs increased by $30.9 million, to $710.8 million per hull for four ships. BIW later was given a fifth destroyer contract in a subsequent award.

Since the loss in the 2013 multi-year, BIW has made attempts to increase the efficiency of the workforce — a key management initiative — to make the General Dynamics yard more competitive with its HII competitor.

“In order to improve our competitive position to win future work, BIW must reduce the cost of building ships in Bath, Maine, to a level the Navy can afford and at a price which is lower than our Mississippi competitors,” BIW officials said earlier this year, according to a May report in

In November 2013 General Dynamics placed NASSCO president Fred Harris — responsible for turning the beleaguered Lewis and Clark–class cargo ship (T-AKE) from one of the service’s worst performing shipbuilding programs into one of the best — in charge of BIW.

Harris spearheaded a series of workforce efficiency drives that have sparked conflicts between unions and management at BIW.

In particular, the lack of qualified electricians at BIW to work on both the Burkes and the Zumwalts has been a bottleneck in both lines, several sources confirmed to USNI News.

A proposal to import electricians from other General Dynamics shipyards – Electric Boat in Groton, Conn., and NASSCO in San Diego, Calif. – was met with intense resistance by the local unions.

“We don’t know if you realize it, but we’re not used to people coming into our yard,” Local S6 machinist union president Jay Wadleigh told

The Heart of the Zumwalt
(I'll skip this part here.)


The following are the complete written statements provided by the Navy and Bath Iron Works in response to questions from USNI News on how delays in the Zumwalt-class were affecting the Arleigh Burke line at BIW.

NAVY:

Zumwalt is approximately 96 percent complete with her production and testing in support of delivery by Bath Iron Works. With limited exceptions, the current forecast is for production to complete by September 2015. The shipboard test program, which is approximately 65 percent complete, comprises the preponderance of remaining effort in support of sea trials and ship delivery. In view of the highly complex ship systems that underpin ZUMWALT’s unique warfighting capabilities, the Navy and shipbuilder are executing the test program for this first of class ship with extreme rigor to ensure the highest standards of quality and completeness when the ship sails. Our current forecast, based on latest test program trends, is that Zumwalt will commence Dock Trials in November, in preparation for the ship’s first underway trial period in December. Schedules for follow ships of the ZUMWALT class, MICHAEL MONSOOR (DDG 1001) and LYNDON B. JOHNSON (DDG 1002), are likewise under evaluation. The Navy is working closely with the shipbuilder to ensure that lessons learned in the course of building and testing the first of class are being fully leveraged to improve performance on these follow ships. As we work to overcome schedule issues on this new ship program, we will maintain our priority on quality and efficiency in order to deliver both destroyer classes under construction at Bath Iron Works, DDG 1000 and DDG 51, in the most cost effective manner possible.

BIW:

DDG 1000 is the first ship of its class and incorporates many cutting edge technologies, integrating them together for the first time. BIW continues to work hard on the complex phase of test and activation, alongside the Navy and other navy contractors.
We are fully under way on the restarted DDG 51 program, with two ships well into construction and a third in early stages. We continue to work with the Navy to manage risk across all our programs, control costs and balance BIW’s workload so we can deliver ships to the fleet as efficiently as possible.

Jeff, hope you're right...
Only time will tell, Jura. But the Zumwalt is 98% complete and is going to sea late this year...and the Monsoor is coming right along. You can see the pic of her above and she is clearly nearing a state where she can be launched.

Apparently, according to this report the LBJ, which is the 3rd vessel, is itself 28% complete, an that is further along than I thought she would be.

The main issue I read it\s that Bath Iron Works, which is building two Zumwalts concurrently, and two Burkes concurrently, is beset with, in essence, too much work as a result of Gates decision to build all three Zumwalts there.

In addition to those our builds going on, they are outfitting the Zumwalt herself and DDG-13.

So they do have a LOT of work, and when you have too much work, invariably things slip unless you increase your fabrication capabilities and your work force.

I do not see BIW doing that since this is, in essence, a bubble that will pass within a few short years.
 
found some news:
Bath Iron Works Gets USS Zumwalt’s Propellers
Rolls-Royce has delivered the twin fixed pitch propellers to Bath Iron Works for installation on the US Navy’s most modern surface combatant, the future USS Zumwalt, the first ship of the DDG 1000 multi-mission destroyer class.

The provision of the twin fixed pitch propellers marks the completion of the power and propulsion system delivery from Rolls-Royce, following the MT30 main turbine generator sets and the RR4500 auxiliary turbine generator sets, which have already been installed and tested.

The five-bladed nickel aluminium bronze propellers measure over 18 feet in diameter and weigh nearly 60,000 pounds apiece. The propellers were cast and machined at the Rolls-Royce facility in Pascagoula, Mississippi. The production of the unique pattern, designed by NAVSEA, began over six years ago, with the first set of finished propellers being delivered by Rolls-Royce from Pascagoula to Bath Iron Works in Bath, Maine in May 2015.

In addition to the twin fixed pitch propellers onboard the Zumwalt are two Rolls-Royce MT30 Main Turbine Generator Sets (MTGs) and two RR4500 Auxiliary Turbine Generator Sets (ATGs) that will provide a total of 78 MW for total ship power – the MTGs provide 35.4 MW each and the ATGs 3.9 MW each. The MT30 MTGs are produced in England, and the RR4500 ATGs are produced in Indianapolis, Indiana.

As of mid-July Zuimwalt was 96% complete and is scheduled for dock trials in November, and initial sea trials in December of this year. That's four months away fro sea trials.

As it is, she too is looking very good. Can't wait for her to plow the waves.
