Construction

The contract to build Seawolf was awarded to the Electric Boat Division of General Dynamics on 9 January 1989 and her keel was laid down on 25 October 1989. She was launched on 24 June 1995, sponsored by Mrs. Margaret Dalton, and commissioned on 19 July 1997. The 7-year 9-month time period from keel laying to commissioning is the longest for a submarine in the U.S. Navy.

Adding support personnel as well as ship's crew, there are 140 personnel assigned or attached to Seawolf.[7]
