The U.S. Navy christened its first DDG-1000 class destroyer, a $3 billion, 610-foot stealth ship with advanced technology. The ship, named after Admiral Elmo Zumwalt, features a composite deckhouse and angular shape to reduce its radar signature. It has an electric propulsion system and will carry state-of-the-art weapons over 60 miles away. The ship will require half the crew of current destroyers and use cameras to monitor activities, allowing it to perform its mission with fewer sailors.
