USS Zumwalt DDG 1000
The USS Zumwalt underway for a brief visit to the Newport Navy Base, on her way to a commissioning ceremony in Baltimore MD.The Zumwalt-class destroyer is a class of United States Navy guided missile destroyers designed as multi-mission stealth ships with a focus on land attack. The class emerged from the previous DD-21 vessel program, previously known as the "DD(X)". The class is multi-role and designed for surface warfare, anti-aircraft warfare, and naval gunfire support. They take the place of battleships in filling the former congressional mandate for naval fire support, though the requirement was reduced to allow them to fill this role. The vessels' appearance has been compared to that of the historic ironclad warship.
The class has a low radar profile; an integrated power system, which can send electricity to the electric drive motors or weapons, the Total Ship Computing Environment Infrastructure (TSCEI), automated fire-fighting systems, automated piping rupture isolation, and may someday include a railgun or free-electron lasers. The class is designed to require a smaller crew and be less expensive to operate than comparable warships. It has a wave-piercing tumblehome hull form whose sides slope inward above the waterline. This will reduce the radar cross-section, returning much less energy than a conventional flare hull form.
The lead ship is named Zumwalt for Admiral Elmo Zumwalt, and carries the hull number DDG-1000. Originally 32 ships were planned, with the $9.6 billion research and development costs spread across the class, but the quantity was reduced to 24, then to 7, and finally to 3, greatly increasing the cost-per-ship.
