The USS Gridley (DLG-21/CG-21) was a Leahy-class guided missile cruiser constructed for the United States Navy. Laid down by the Puget Sound Bridge and Drydock Company in Seattle, Washington, her keel was established prior to her launch on 31 July 1961. Sponsored by Mrs. Stuart D. Rose, she was commissioned on 25 May 1963. The vessel’s design incorporated advanced radar, sonar, and missile systems, making her a significant component of the Navy's surface fleet. Throughout her service, the Gridley operated extensively in the Pacific and Southeast Asian regions. After initial outfitting and acceptance trials out of Long Beach, California, she served as the flagship of Destroyer Squadron 19. Her early deployments included goodwill visits to Australia, participation in commemorations of the Battle of the Coral Sea, and operational duties off Vietnam, notably escorting the aircraft carrier USS Constellation and performing screening, picket, and communication relay tasks during the Vietnam War. Her notable service in the Gulf of Tonkin earned her the Navy Unit Commendation. The ship underwent multiple upgrades, including a major re-commissioning in 1970 with advanced radar and missile systems, such as NTDS and digital missile fire control capable of launching Standard Missile Type 2. Reclassified as a guided missile cruiser (CG-21) in 1975, she provided critical air traffic control and station support during operations like "Operation Frequent Wind" and the Mayagüez incident. Her service also included involvement in the aftermath of the Axe Murder Incident in Korea, and she played a role in escorting reflagged Kuwaiti oil tankers during Operation Earnest Will. The USS Gridley received several awards, including the Capt. Edward F. Ney Memorial Award for best food service and recognition for battle efficiency and supply performance. She was extensively modernized in the early 1980s, upgrading her radar, sonar, and missile capabilities. Her later years saw deployments in the Persian Gulf supporting Operation Southern Watch, rescuing refugees, and participating in regional security operations. Decommissioned and stricken from the Naval Vessel Register in 1994, the USS Gridley was eventually scrapped in 2005, marking the end of a distinguished service history as a versatile and technologically advanced surface combatant.
