USS Atlas (ARL-7) was one of 39 Achelous-class landing craft repair ships built for the United States Navy during World War II.

She arrived in Baltimore, Maryland on 14 December 1943; entered the Bethlehem Steel Key Highway Shipyard; and was placed out of commission for her conversion to a landing craft repair ship.

After shakedown training along the Atlantic coast, Atlas departed Boston, Massachusetts at the end of the second week in March and steamed via Halifax, Nova Scotia to the British Isles.

Though not present for the actual assault, Atlas arrived on the scene on 8 June, two days after "D-Day," and immediately began repairing damaged landing craft.

Her crew worked about 14 hours a day returning their charges to active service while frequently fighting to fend off enemy air attacks.

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 stood out of San Diego on the 16th of that month for another tour of duty in the Far East, reentered Yokosuka on 15 April, and resumed repair work on American amphibious warfare ships and craft operating in the Orient.

On 21 September, Atlas weighed anchor at Yokosuka and shaped a course via Pearl Harbor for home and arrived at San Diego on 19 October.
