Approximately 20 percent of ''North Dakota'' was redesigned to lower acquisition cost and increase operational flexibility. The changes include a ship's bow redesign, replacing 12 individual launch tubes with two large-diameter Virginia Payload Tubes, each capable of launching six UGM-109 Tomahawk cruise missiles.〔 〕 The contract to build her was awarded to Electric Boat division of General Dynamics in Groton, Connecticut on 14 August 2003.

The U.S. Navy accepted delivery of ''North Dakota'' on 29 August 2014 two days prior to its contract delivery date. The submarine successfully completed Alpha, Bravo, and Board of Inspection and Survey (INSURV) trials, which evaluate the submarine's seaworthiness and operational capabilities. During the trials, the crew took the submarine to test depth, conducted an emergency surfacing, and tested the submarine's propulsion plant. The U.S. Navy postponed ''North Dakota''´s original commissioning date of May 2014 because of quality issues with vendor-assembled and delivered components that required an unplanned dry-docking to correct. Additional design certification work was also required on the submarine's redesigned bow. ''North Dakota'' was commissioned on 25 October 2014 in Groton, Connecticut. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「USS North Dakota (SSN-784)」の詳細全文を読む スポンサード リンク
