Only a few Atlantas were available early, and Atlanta and Juneau were both lost during the Guadalcanal campaign. Later units arrived slowly even though their batteries would have been useful around carrier forces and a projected invasion of Japan. After those losses, only San Diego and San Juan were available until Oakland commissioned in July 1943, so the type never shaped Pacific screens in mass.
