"Atlas" remained inactive until midway through 1951 when the Fleet was expanding to meet the demand for warships caused by fighting in Korea. She was recommissioned at Astoria on 1 June 1951, Lieutenant Commander Jaroslav Kohl in command, and operated along the west coast until early November. On the 12th, the landing craft repair ship got underway for the Far East and made a stop at Pearl Harbor from 24 November to 1 December before continuing on to Japan. She arrived at Yokosuka on 21 December and, for the next nine months, repaired amphibious warfare ships and craft damaged in the Korean War. She operated primarily at Yokosuka and Sasebo but also saw service at Okinawa. On 25 September 1952, she left Yokosuka and shaped a course back to the United States. The ship stopped off at Pearl Harbor before continuing on to San Diego where she arrived on 24 October.
