The Zumwalt (DDG-1000) is a planned class of United States Navy destroyers, designed as multi-mission ships with a focus on land attack. Including research and development, the cost of the Zumwalt class ships was estimated at more than $7 billion, instead of building 25 the Navy will only get 3 due to the cost overruns, as the original cost projected at $2.5 Billion.
“The class is planned to feature a low radar profile; an integrated power system, which can send electricity to the electric drive motors or weapons, which may some day include a railgun or free-electron lasers; total ship computing environment infrastructure, serving as the ship’s primary LAN and as the hardware-independent platform for all of the ship’s software ensembles; automated fire-fighting systems and automated piping rupture isolation. The class is designed to require a smaller crew and be less expensive to operate than comparable warships. It will have 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 more hard-angled hull form. As of January 2009, the GAO found that only four out of 12 of the critical technologies were mature.” (Source: Wikipedia)
