World War II service
Following shakedown exercises, Marathon underwent amphibious training operations off the southern California coast and in the Hawaiian Islands. On 24 January 1945, she departed Pearl Harbor, with army, marine, and naval passengers, and steamed independently for Espiritu Santo and Guadalcanal. She arrived in the New Hebrides 2 February, disembarked her army passengers and general cargo and continued on to the Solomons, arriving at Guadalcanal on the 7th. At the end of the month, the transport commenced a period of intensive amphibious exercises in preparation for the upcoming Okinawa campaign.

On 22 March she got underway for Ulithi, conducting gunnery drills en route, and 27 March sailed with the fleet for the Ryukyus. Just before dawn, 1 April, Marathon began dispatching her boats toward the beaches. Commencing with smoke boats, she continued unloading troops and cargo into the afternoon. losing only one of her landing craft, with no casualties, to enemy fire. The transport remained in the assault zone until 5 April when she headed for the Marianas. From Saipan, she returned to Pearl Harbor, arriving on the 20th for maintenance. Following training, Marathon called at San Francisco, California, to embark troops bound for Hawaii. She returned to Pearl Harbor 8 June and headed for the western Pacific Ocean 2 days later, steaming via Eniwetok and Ulithi, for Okinawa. Marathon reached that island 14 July and proceeded into newly named Buckner Bay, where she discharged passengers and cargo.

On 22 July, while at anchor in Buckner Bay Marathon’s hull trembled with a force of a violent explosion. Postwar examination of Japanese records indicates that the explosion, which resulted in extensive damage, was caused by a kaiten, a one-man suicide Japanese submarine.

Post-war activity
Following prolonged repairs, on 16 September Marathon sailed to Nagasaki to embark ex-prisoners of war of varying nationality for transport to Okinawa. From October to February she swept minefields in the Nagoya, Hiro Wan, and Ise Wan areas.

Marathon headed for the United States in late February 1946. She decommissioned and returned to her owners at San Francisco 8 May.

Marathon received two battle stars for World War II service at Okinawa.
