Lockheed Martin and Fincantieri Marinette Marine have begun construction on the future USS Nantucket, the US Navy's 14th Freedom-class littoral combat ship (LCS).
The LCS will be the third US Navy ship to be named in honour of the island of Nantucket in the US state of Massachusetts.
The 115- by 17.5-metre Nantucket will be capable of speeds of up to 40 knots and will be used to support mine countermeasures, anti-submarine warfare (ASW), and surface warfare missions.
