21 July 2014

Huntington Ingalls Industries (NYSE: HII) said it has completed the builder´s sea trials for the company´s fourth US Coast Guard National Security Cutter, Hamilton (WMSL 753).

The ship, built by HII´s Ingalls Shipbuilding division, spent three full days at sea testing all of the ship´s systems.

Ingalls has delivered the first three NSCs, and three more are currently under construction. A seventh NSC, Kimball WMSL 756, is scheduled to begin construction in early 2015.

Legend-class NSCs are the flagships of the Coast Guard´s cutter fleet. Designed to replace the 378-foot Hamilton-class High-Endurance Cutters that entered service during the 1960s, they are 418 feet long with a 54-foot beam and displace 4,500 tons with a full load. They have a top speed of 28 knots, a range of 12,000 miles, an endurance of 60 days and a crew of 110.
