USS Flatley (FFG-21) was the thirteenth ship of the Oliver Hazard Perry class of guided-missile frigates. She was the first ship of the U.S. Navy to be named for Vice Admiral James H. Flatley (1906–1958), a leading Naval Aviation tactician from World War II who flew the F4F Wildcat in the Battle of Coral Sea and subsequently commanded the VF-10 Grim Reapers taking them into combat for the first time.
