About the Zumwalt class destroyer

The Zumwalt-class destroyer is a class of three United States Navy guided-missile destroyers designed as multi-mission stealth ships with a focus on land attack.

It is a multi-role class that was designed with a primary role of naval gunfire support and secondary roles of surface warfare and anti-aircraft warfare. The class design emerged from the DD-21 "land attack destroyer" program as "DD(X)" and was intended to take the role of battleships in meeting a congressional mandate for naval fire support.

These ships are classed as destroyers, but they are much larger than any other active destroyers or cruisers in the U.S. Navy. The vessels' distinctive appearance results from the design requirement for a low radar cross-section (RCS).

The Zumwalt class has a wave-piercing tumblehome hull form whose sides slope inward above the waterline, dramatically reducing RCS by returning much less energy than a conventional flare hull form.

The class has an integrated electric propulsion (IEP) system that can send electricity from its turbo-generators to the electric drive motors or weapons, the Total Ship Computing Environment Infrastructure (TSCEI), automated fire-fighting systems, and automated piping rupture isolation. The class is designed to require a smaller crew and to be less expensive to operate than comparable warships.
