USS Seawolf (SSN-21)

The USS Seawolf (SSN-21) was one of four Seawolf-class nuclear attack submarines in the United States Navy. She is the fourth submarine of the United States Navy named for the seawolf, a solitary fish with strong, prominent teeth and projecting tusks that give it a savage look. The contract to build her was awarded to General Dynamics Electric Boat and Newport News Shipbuilding on January 9th, 1989 and her keel was laid down on October 25th that same year. She was launched on June 24th, 1995, sponsored by Mrs. Margaret Dalton, and commissioned on July 19th, 1997 with Commander David M. McCall in command.

USS Seawolf featured in a 1998 episode of the documentary Super Structures of the World: Seawolf. The program followed her construction and sea trials.

Seawolf was taken down at the 2004 RIMPAC exercises by the Canadian submarine Lake Superior.

Between March 25th-27th 2006, a series of anti-submarine warfare exercises were held in Hawaiian waters that included Seawolf; Carrier Strike Group Nine (then centered around aircraft carrier Abraham Lincoln); the nuclear-powered attack submarines Cheyenne, Greeneville, Tucson, and Pasadena, as well as land-based P-3C Orion maritime patrol aircraft from patrol squadrons VP-4, VP-9, and VP-47.

On July 22nd, 2007, the submarine transferred from her previous homeport of Naval Submarine Base New London in Groton, Connecticut, to permanently reside at SubBase Bangor in Silverdale, Washington.

During the Second Korean War, Seawolf was deployed as part of Surface Strike Group 2 centered around the battleship New Jersey.
