USS Gridley (DLG-21) was a Leahy-class guided-missile cruiser commissioned in 1963 under the destroyer leader designation DLG-21 — later reclassified CG-21. Named for Rear Admiral Charles Vernon Gridley, who received Commodore George Dewey's legendary order "You may fire when you are ready, Gridley" at the Battle of Manila Bay in 1898, she served as a capable surface combatant throughout the Cold War in the Pacific Fleet.
