USS Hartford, a sloop-of-war steamer, was the first ship of the United States Navy named for Hartford, the capital of Connecticut. Hartford served in several prominent campaigns in the American Civil War as the flagship of David G. Farragut, most notably the Battle of Mobile Bay in 1864. She survived until 1956, when she sank awaiting restoration at Norfolk, Virginia.

David Glasgow Farragut was a flag officer of the United States Navy during the American Civil War. He was the first rear admiral, vice admiral, and admiral in the United States Navy. He is remembered for his order at the Battle of Mobile Bay, usually paraphrased as "Damn the torpedoes, full speed ahead" in U.S. Navy tradition.
