USS Boston (CA-69/CAG-1), a Baltimore-class heavy cruiser and later a Boston-class guided missile cruiser, was the sixth ship of the United States Navy to be named for the U.S. city of Boston, Massachusetts.

Boston was launched 26 August 1942 by Bethlehem Steel Company’s, Fore River Shipyard in Quincy, Massachusetts; sponsored by Mrs. Helen Noonan Tobin, wife of the Mayor of Boston, Maurice J. Tobin; and commissioned 30 June 1943, Captain J. H. Carson in command

Recommissioned as guided missile cruiser[edit]

Boston (along with Canberra and Chicago) was not recommissioned for service during the Korean War as were 10 others of her class, but was earmarked for conversion to carry guided missiles and reclassified CAG-1 on 4 January 1952. In February 1952 she was towed from Bremerton, Washington, to Philadelphia for conversion to a guided missile heavy cruiser by New York Shipbuilding Corporation, Camden, New Jersey. During conversion her aft 8-inch turret was replaced with Terrier Surface-to-air missile launchers and she was modernized. Boston was recommissioned 1 November 1955 as the lead ship of her class and operated along the east coast and in the Caribbean conducting missile evaluations and participating in fleet exercises until departing for the Mediterranean 23 November 1956. She returned in May 1957.

After making a Midshipmen‘s cruise to South America, taking part in NATO exercises in the North Atlantic, and receiving an overhaul, Boston made her second Sixth Fleet tour during June–September 1958. This cruise included participation in the Lebanon crisis. During the next eight years, she frequently operated in the Mediterranean, often in the role of flagship, taking part in exercises off Northern Europe, the Caribbean and off the US East Coast. Boston served as flagship for the recovery effort of the Palomares Incident from February through April 1966
