She later served in the Korean and Vietnam Wars as a civilian-crewed Military Sea Transportation Service vessel, as USNS General John Pope (T-AP-110).

From 6 October to 19 November she made a troop-carrying voyage to Brisbane, Australia; and, after touching Townsville and Milne Bay, put in at San Francisco on the latter date.

General John Pope then embarked another full complement of troops, including the 1st Filipino Infantry Regiment, and sailed 6 April for Nouméa and Oro Bay, New Guinea.

Nearly 4,000 fighting men, mainly troops of the New Zealand Expeditionary Forces, were embarked and delivered safely to Melbourne and Wellington before the ship moored again at San Pedro 16 January 1945.

Finally, missions accomplished, General John Pope departed San Francisco 15 May bound for New York, where she decommissioned 12 June 1946 and was returned to the War Shipping Administration (WSA).

During the Korean War she carried American troops to Japan and Korea to take part in the giant effort to hold back the Communist invasion.

Following the war, General John Pope continued to sail to Japanese and Korean ports on troop rotation duties, finally being placed in reduced operational status at Seattle 14 May 1955.

On 23 July 1966, elements of the 64th Transportation Company boarded the General John Pope, and departed from the Tacoma, Washington Outport Facility, arriving in Okinawa on 5 August 1966.

The final years of the General John Pope began when she was placed out of commission once again on 1 May 1970, transferred to MARAD, and laid up in the National Defense Reserve Fleet at Suisun Bay, California.

On 18 May 2010, the last surviving P2-S2-R2 U.S. Army Transport vessel of her type, the General John Pope departed San Francisco Bay for her final voyage to Texas.

After a brief stop in San Pedro California, she made passage through the Panama Canal on 15 June 2010, continuing on to ESCO Marine in Brownsville, Texas where she arrived at her final destination for dismantling.
