USS Thach (FFG-43), an Oliver Hazard Perry-class frigate, was the only ship of the United States Navy named for Admiral John Thach, a Naval Aviator during World War II, who invented the Thach Weave dogfighting tactic. Thach was laid down on 6 March 1981 by the Todd Pacific Shipyards, Los Angeles Division, San Pedro, California; launched on 18 December 1982; sponsored by Mrs. Madalyn J. Thach, widow of the namesake; and commissioned on 17 March 1984 at Long Beach, Cmdr. Dale H. Moses in command. She was the frigate long-hull variant (Flight II).
