A wrecked warship discovered decades ago off the Florida Keys has been identified as a British frigate that sank in the 18th century.

National Park Service archaeologists used new research to determine that the wreckage first spotted in 1993 near Dry Tortugas National Park is the HMS Tyger, the agency said.
