The $2.6 billion, 377-foot-long USS North Dakota will return to its home port of Groton, Connecticut, on Jan. 31 after a six-month deployment, the Minot Daily News reported.
The submarine is able to launch cruise missiles, deliver special forces and carry out surveillance.
The deployment included 68 days of operations that required "the most rigorous attention," said Mark Robinson, USS North Dakota's commanding officer. "But the team didn't blink. They pulled off a very impressive mission which completed one of the highest priorities of the chief of Naval Operations."
Bob Wefald, chairman of the USS North Dakota Committee from Bismarck, said, "We are very pleased our boat and its crew have had successful deployment so far, carrying out missions of critical importance to our country."
The USS North Dakota is just the second Navy vessel named for North Dakota. A World War I-era battleship was also named for the state.
The submarine was commissioned at Groton in 2014.
