USS Minnesota (SSN 783), the US Navy’s tenth Virginia-class submarine, has successfully completed its Alpha and Bravo sea trials at Huntington Ingalls Industries‘ (HII) Newport News Shipbuilding (NNS) division in Virginia, US.
USS Minnesota’s Alpha sea trials involved testing depth, conducting an emergency surfacing, and checking the submarine’s propulsion plant to evaluate seaworthiness and operational performance, while Bravo trials validated its acoustic performance and combat systems.
Built by General Dynamics Electric Boat and HII, USS Minnesota is expected to be delivered approximately one year earlier than its contract delivery date.
Minnesota commander, commander John Fancher said: "The events required during sea trials are some of the most demanding tasks a submarine can be asked to do."
