Largest destroyer built for Navy headed to sea for testing

BATH, Maine (AP) — The largest destroyer ever built for the U.S. Navy headed out to sea for the first time Monday, departing from shipbuilder Bath Iron Works and carefully navigating the winding Kennebec River before reaching the open ocean where the ship will undergo sea trials.

More than 200 shipbuilders, sailors and residents gathered to watch as the futuristic 600-foot, 15,000-ton USS Zumwalt glided past Fort Popham, accompanied by tugboats.

For the crew and all those involved in designing, building, and readying this fantastic ship, this is a huge milestone, the ship's skipper, Navy Capt. James Kirk, said before the ship departed.

The ship has electric propulsion, new radar and sonar, powerful missiles and guns, and a stealthy design to reduce its radar signature.

Critics say the "tumblehome" hull's sloping shape makes it less stable than conventional hulls, but it contributes to the ship's stealth and the Navy is confident in the design.

Eric Wertheim, author and editor of the U.S. Naval Institute's "Guide to Combat Fleets of the World," said there's no question the integration of so many new systems from the electric drive to the tumblehome hull carries some level of risk.
