The USS Tutuila (ARG-4) was an internal combustion engine repair ship that saw service in the United States Navy during World War II, The Korean War, and The Vietnam War as well as several smaller actions. Named for the Island of Tutuila, the largest and main island of American Samoa, it was the second U.S. Naval vessel to bear the name. Originally laid down as Arthur P. Gorman under a Maritime Commission contract (MC hull 1179) on 11 August 1943 at Baltimore, MD, by the Bethlehem Steel Co.; renamed Tutuila on 8 September 1943 and designated ARG-4; launched on 12 September 1943; transferred to the Navy when 80 percent complete for conversion to an internal combustion engine repair ship on 18 September; converted by the Maryland Drydock Co.; and commissioned there on 8 April 1944, Comdr. George T. Boldizsar in command.

In the wake of the liberation of the Philippines, Tutuila arrived at Leyte on 24 May 1945 and provided repair services there to a wide variety of ships and smaller craft from the date of her arrival until the end of hostilities. After the war, Tutuila's work was far from over. As American and Allied forces prepared for occupation of the Japanese homeland, the ship joined those forces headed north for duty off Japan's shores. On 30 August, Tutuila—in company with USS Jason (ARH-1), USS Whitney (AD-4), and 11 smaller ships—set out on the first leg of the voyage northward. One day out, a typhoon lashed at the convoy, forcing the slower repair ship to remain with the "small boys" while Jason and Whitney received orders to run for Japan.

On 2 September, having weathered the storm and shepherded her charges to safe harbor, Tutuila dropped anchor in Buckner Bay (Nakagusuku Bay), Okinawa. From there, Tutuila proceeded with a 33-ship convoy, bound for Korea, making port at Jinsen (Incheon) on 24 September 1945. She operated there as a maintenance vessel for ships engaged in the repatriation of Japanese prisoners of war. She continued this work after moving to Taku, China, where she arrived on 26 January 1946. Departing Taku on 30 March, the ship steamed to Shanghai, China, where she dropped anchor on 2 April. Six days later, she sailed for the United States. The ship transited the Panama Canal and arrived at New Orleans, LA on 20 May. Following repairs, she moved to Galveston, TX, on 9 June 1946 for deactivation and was decommissioned there six months later, on 7 December 1946.
