Of the seventeen (including the three "Oregon City"s) completed ships, twelve were commissioned before the Japanese capitulation on September 2, 1945, though only seven took part in the battles of the Pacific Theater and one in the European Theater. By 1947, nine of the "Baltimore"s had been decommissioned and placed in the reserve fleet, while seven ("Helena", "Toledo", "Macon", "Columbus", "Saint Paul", "Rochester", and "Albany") remained in service. However, at the start of the 1950s, six were reactivated ("Macon" had been decommissioned for four short months: June–October 1950), making thirteen available for deployment in the Korean War. Six of these were used for escort missions and coastal bombardment in Korea, while the other seven reinforced fleets in other areas of the globe. Four ships remained out of service: the "Fall River" was never reactivated, the "Boston" and "Canberra" were refitted as "Boston"-class guided missile cruisers (CGs), and the "Chicago" was reactivated after being converted to an "Albany"-class CG.
