After shakedown operations out of San Diego, General H. B. Freeman departed San Pedro 1 June 1945 with 3,040 troops and passengers for Calcutta, India, where she arrived 9 July with 16 additional passengers, British Royal Marines who had embarked at Brisbane, Australia. On 13 July she was underway with more than 3,000 military passengers; embarking and debarking in Ceylon, Australia, New Guinea, and the Philippines before arriving Hagushi, Okinawa, 16 August 1945, the day after hostilities ended.
More than 1,000 homeward-bound veterans boarded the transport which departed Okinawa 21 August 1945 headed via Saipan and Pearl Harbor for the West Coast, arriving San Pedro, California, 12 September 1945. She sailed 7 October, carrying occupation troops to Tokyo, and returned to Seattle, Washington, 5 November as the "Magic-Carpet" home for more than 3,000 fighting men from the Pacific War. General H. B. Freeman made a similar passenger run from Seattle to Yokohama and back (16 November – 16 December 1945).
She next entered the Puget Sound Naval Shipyard, Bremerton, Washington, for inactivation overhaul and decommissioned there 4 March 1946. She was redelivered to the Maritime Commission for service with the Army's peacetime transport fleet.
General H. B. Freeman was reacquired by the Navy 1 March 1950 and assigned to MSTS. Manned by a civil service crew, General H. B. Freeman carried military passengers throughout the Korean War from the West Coast to Korea, Japan, and island bases in the Pacific.
She was in the fleet that evacuated Hŭngnam. Her distinguished service won her the "Smart Ship Award" for three consecutive years (1950, 1951, and 1952). The transport continued to operate throughout the Pacific until 24 July 1958 when her name was again struck from the Navy List. She was returned to the Maritime Commission and to the National Defense Reserve FleetOlympia, Washington, where she remained until sold for commercial service in 1967 under the MARAD Ship Exchange Program.
The ship was rebuilt in 1968 by Todd Shipyards, Galveston, TX as the container ship SS Newark, USCG ON 511486, IMO 6903199, for Sea Land Service. She was sold for scrapping in Taiwan in 1986.[1][3][4]
