USS Nebraska (SSBN-739)

The contract to build Nebraska was awarded on 26 May 1987 to the Electric Boat Division of the General Dynamics Corporation at Groton, Connecticut. Her keel was laid there on 6 July 1987 and she was launched on 15 August 1992, sponsored by Patricia Exon, the wife of United States Senator J. James Exon (1921–2005) of Nebraska. Nebraska was delivered to the U.S. Navy on 18 June 1993 and commissioned on 10 July 1993. ==Service history==

Nebraska was originally assigned to Submarine Group 10 at Naval Submarine Base Kings Bay, Georgia. On 1 October 2004, Nebraska was transferred to Submarine Squadron 17 in Submarine Group 9 at Naval Base Kitsap, Bangor, Washington. In 2013 Nebraska transferred to Submarine Squadron 19 to conduct an Engineering Refueling Overhaul. The sub has successfully launched Trident missiles for testing six times, once in 1993, in 2004, in 2008, in 2011 in 2018, and in 2019. As of November 2013, the submarine had completed 62 deterrent patrols during her 20 years of service. Each patrol is usually 77 days in duration followed by 35 days in port for maintenance. Following Patrol 54, Nebraska was awarded the "Battle E" for Submarine Squadron 17. Additionally, following Patrol 56, the submarine was awarded the "Battle E" for Submarine Squadron 17 for its second consecutive year. After completing an unprecedented 116-day patrol in late 2013, Nebraska was again awarded the "Battle E," her third in four years. ==In popular culture==

In the military hard science fiction Looking Glass series by John Ringo and Travis S. Taylor, Nebraska is converted into the first human interstellar spaceship and renamed Vorpal Blade. The boat is the main setting for the majority of the second, third, and fourth books in the series, Vorpal Blade, Manxome Foe, and Claws That Catch. == Related reading ==
