Ingalls Shipbuilding delivers composite deckhouse for DDG-1001
Huntington Ingalls Industries' Ingalls Shipbuilding division has delivered to the U.S. Navy the second of two 900-ton deckhouses for the destroyer Michael Monsoor (DDG-1001).
Huntington Ingalls Industries' (Gulfport, Miss., USA) Ingalls Shipbuilding division reported on Aug. 7 that it has delivered the composite deckhouse for the destroyer Michael Monsoor (DDG-1001) to the U.S. Navy. The 900-ton deckhouse provides an advanced structure that will house the ship's bridge, radars, antennae and intake/exhaust systems and is designed to provide a significantly smaller radar cross-section than any other ship in today's fleet.
Ingalls built and delivered the composite deckhouse and hangar for DDGs 1000 and 1001 at the company's Composite Center of Excellence in Gulfport. Made almost exclusively using cored composite construction processes, the deckhouse and hangar take full advantage of the properties of the carbon fiber materials and balsa wood cores. The composite deckhouse provides the unique performance and technical capability necessary in the Zumwalt class of destroyers. The structure is as strong as steel, at significantly less weight. The composite deckhouse also reduces maintenance cost over the life span of the ship due to its corrosion resistance in the marine environment.
The deckhouse will be placed on a barge and shipped to General Dynamics Bath Iron Works in Maine, USA, to be integrated onto the steel hull of DDG 1001.
"This is a very unique structure for a very unique ship," says Kevin Amis, program director, DDG 1000 Program. "Wherever she goes in the future, the shipbuilders of the Gulfport Composite Center of Excellence will know that they had a hand in building one of the most complex carbon fiber structures ever built."
"I am extremely proud of the men and women of the Supervisor of Shipbuilding Gulf Coast and Ingalls Shipbuilding for their outstanding accomplishment in manufacturing the DDG-1001 deckhouse," says Jonathan Graves, DDG 1000 program manager's representative, supervisor of Shipbuilding Gulf Coast. "This complex and cutting-edge composite deckhouse will serve as the heart of the USS Michael Monsoor. We are extremely honored to have a role in celebrating a great American and Medal of Honor-winning hero."
