American Atlanta-class ships were designed as destroyer flotilla leaders but were mainly used as AA defense cruisers to escort aircraft carrier forces. The main caliber of these ships was represented by dual-purpose 5-inch guns. A total of 11 ships of this class were built; 2 of them were lost during World War II, and the rest were incapacitated between 1959 and 1965. In the 1960s, the Thai Navy needed ships, and given the alliance between the countries, they had a chance to consider acquiring decommissioned American cruisers.
