Future USS Zumwalt underway for the first time conducting at-sea tests and trials in the Atlantic Ocean

The future USS Zumwalt (DDG 1000) is underway for the first time conducting at-sea tests and trials in the Atlantic Ocean Dec. 7, 2015. The multimission ship will provide independent forward presence and deterrence, support special operations forces, and operate as an integral part of joint and combined expeditionary forces.

BATH, Maine, April 1, 2015 /PRNewswire/

 

The U.S. Navy has awarded funding for the construction of DDG 122, the Fiscal Year 2015 Arleigh Burke-class destroyer under contract at General Dynamics Bath Iron Works. This $610.4 million contract modification fully funds this ship which was awarded in 2013 as part of a multi-ship competition for DDG 51 class destroyers. The total value of the five-ship contract is approximately $3.4 billion. General Dynamics Bath Iron Works is a business unit of General Dynamics (NYSE: GD).

Fred Harris, president of Bath Iron Works, said, "This announcement allows us to continue efforts associated with planning and construction of DDG 122. We appreciate the leadership of Senators Collins and King and the strong support of our entire delegation in matters of national defense. We are grateful for their recognition of the contributions made by the people of BIW to the U.S. Navy's important shipbuilding programs."

There are currently three DDG 51 destroyers in production at Bath Iron Works, Rafael Peralta (DDG 115), Thomas Hudner (DDG 116) and Daniel Inouye (DDG 118). The shipyard began fabrication on DDG 115 in November 2011, and delivery to the Navy is scheduled for 2016. Fabrication on DDG 116 began in November 2012, and that ship is scheduled to be delivered to the Navy in 2017. Fabrication has just begun on DDG 118, the first ship of the 2013 multi-ship award.

Bath Iron Works is also building the three ships in the planned three-vessel Zumwalt-class of destroyers, Zumwalt (DDG 1000), Michael Monsoor (DDG 1001) and Lyndon Johnson (DDG 1002).

The Arleigh Burke-class destroyer is a multi-mission combatant that offers defense against a wide range of threats, including ballistic missiles. It operates in support of carrier battle groups, surface action groups, amphibious groups and replenishment groups, providing a complete array of anti-submarine (ASW), anti-air (AAW) and anti-surface (ASUW) capabilities. Designed for survivability, the ships incorporate all-steel construction and have gas turbine propulsion. The combination of the ships' AEGIS combat system, the Vertical Launching System, an advanced ASW system, two embarked SH-60 helicopters, advanced anti-aircraft missiles and Tomahawk anti-ship and land-attack missiles make the Arleigh Burke class the most powerful surface combatant ever put to sea.

 

Bath Iron Works currently employs roughly 5,600 people.

WASHINGTON — Problems with the complex technology being installed in the new destroyers of the Zumwalt class have forced the Navy and shipbuilder General Dynamics Bath Iron Works to delay delivery of the first two ships, the US Navy said Monday night.

 

The Zumwalt (DDG 1000) had been scheduled to be delivered to the Navy this summer, but that has dropped back to November. Delivery of the second ship, Michael Monsoor (DDG 1001), production of which is about a year behind Zumwalt, has also been pushed back a few months in 2016, to November of that year.

 

Work on the third and last ship in the class, Lyndon B. Johnson (DDG 1002), has not been affected, and that ship is still scheduled for delivery in December 2018.

 

"The schedule delay is due primarily to the challenges encountered with completing installation, integration and testing of the highly unique, leading edge technology designed into this first-of-class warship," Cmdr. Thurraya Kent, spokeswoman for the Navy's acquisition directorate, said in a statement.

 

The three ships are all under construction at GD's shipyard in Bath, Maine. Zumwalt was launched last October and is 94 percent complete, Kent said, and the ship is expected to begin engineering sea trials later this year. Monsoor is scheduled for launch this year as well.

 

Bath also builds Aegis destroyers of the DDG 51 Arleigh Burke class. Completion delays with Zumwalt and Monsoor could affect Aegis destroyer production, Kent indicated.

 

"Navy and General Dynamics Bath Iron Works continue to work together in evaluating schedule impacts for all ships under construction in Bath, Maine, which also includes ships under construction for the Aegis Class Destroyer Program," Kent said in the statement. "Both the Navy and BIW are committed to collectively managing risks and controlling costs to deliver both DDG 1000 and DDG 51-class ships to the fleet in the most efficient manner possible."

 

The DDG 1000 design features an innovative, integrated power system able to switch electrical power between propulsion, sensor and weapon systems, along with a new combat system and numerous technical innovations. The Pentagon's Office of Test and Evaluation did not discuss the DDG 1000 in its latest report on selected acquisition programs, issued in January, and in its report a year earlier did not discuss any major technical problems with the ships' construction.

WASHINGTON - La Marine américaine s'apprête à baptiser samedi l'USS Zumwalt, premier d'une nouvelle classe de destroyers aux formes futuristes qui ne sera finalement développée qu'en trois exemplaires en raison de son coût de développement et d'une réévaluation des besoins.

 

Le navire, dont la construction a débuté en 2009, doit entrer en service en 2016. La cérémonie de baptême, au cours de laquelle une bouteille de mousseux sera brisée sur la coque comme le veut la tradition, se déroulera sur le chantier naval de Bath, dans le Maine (nord-est), précise l'US Navy dans un communiqué.

 

Le Zumwalt, nommé en l'honneur d'un ancien chef d'état-major de la Marine américaine, a été conçu comme un navire multi-missions axé sur des capacités de bombardement terrestre et naval grâce à deux canons de 155 mm. Il est également doté de 80 tubes de lancement de missiles, adaptés notamment pour les missiles Tomahawk.

 

Il comprend de nombreuses technologies nouvelles, notamment en matière de propulsion, qui lui permettent d'opérer avec un équipage réduit à 158 hommes contre 276 pour les destroyers de la classe Arleigh-Burke, en service depuis le début des années 1990.

 

Il est également plus gros, jaugeant plus de 15.000 tonnes, contre moins de 10.000 pour les Arleigh-Burke.

 

L'US Navy compte actuellement 62 destroyers de classe Arleigh Burke, dont 25 sont équipés du système de défense antibalistique (BMD) et constituent le fer de lance du bouclier antimissile américain.

 

Le Zumwalt, qui sera suivi du Michael-Monsoor et du Lyndon-Johnson, en est en revanche dépourvu.

 

L'US Navy comptait à l'origine se doter de 24 destroyers de la classe Zumwalt. Elle n'en aura finalement que trois après avoir réévalué en 2008 les types de menaces auxquelles elle s'attend à faire face dans les décennies à venir.

 

Mais cette décision est également dû au dérapage des coûts de développement du navire, une inflation aggravée par la baisse du nombre de navires finalement décidée: le Zumwalt coûtera plus de 4 milliards de dollars, contre environ 1,5 milliards pour un destroyer de la classe Arleigh-Burke.
