Zumwalt Milestone at Bath Iron Works 

Maine’s Bath Iron Works is marking a milestone in construction of the Zumwalt, the largest ship built in more than two decades at the shipyard. Two daughters and son of the warship’s namesake, the late Adm. Elmo “Bud” Zumwalt, participated in Thursday’s keel-laying ceremony at Bath Iron Works. Traditionally, the ceremony marks the setting of the keel, the massive beam that served as the foundation of the wooden hull. In modern times, there’s no keel, so the ceremony marks the first completed hull segment. In this case, the hull segment is 180 feet long and weighs 4,000 tons. When it’s completed, the stealth destroyer will displace 14,500 tons, making it the biggest Navy ship built in Bath since delivery of an oil tanker to the Military Sealift Command in 1984. (AP)
