Ingalls is building the composite deckhouse and hangar for the DDG 1000 class 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 carbon fiber materials and balsa wood cores. When cured, the composite structure is as strong as steel but requires little maintenance and is very lightweight. These unique attributes reduce maintenance cost over the life span of the ship due to its corrosion resistance in the marine environment and allow for improved hull stability, more payload and increased ship speeds. The Gulfport facility also builds composite masts for the Navy's San Antonio (LPD 17) class of amphibious ships.The deckhouse structure will be integrated to join the other eight of nine "ultra units" making up DDG 1000. This is a process that is similar to the integration process already used with the LPD masts. Steel base plates that are bolted to the composite structure will be welded to the steel hull of DDG 1000. Ingalls delivered the composite hangar and the aft peripheral vertical launch system units for DDG 1000 and has begun work on the composite components for DDG 1001.
