Seawolf III (SSN-21)

1997–

Anarhichas Lupus, a fish known for its ferocious nature. The third U.S. Navy ship (all submarines) named Seawolf. The first Seawolf (SS-197) served from 1939–1945, and the second (SSN-575) from 1957–1987. Seawolf (Submarine Torpedo Boat No. 28), authorized on 3 March 1909, was renamed H-1 on 17 November 1911, two years before she was commissioned, and thus never served under the name.
