Following the outbreak of Communist aggression In South Korea, "Marine Lynx" was acquired by the US Navy from the Maritime Commission 23 July 1950; placed in service; and assigned to duty with Military Sea Transportation Service (MSTS). Manned by a civil service crew, she served throughout the years of the Korean conflict carrying US troops to Japan and the war‑torn Korean peninsula. Between mid‑December 1950 and 20 August 1954, she deployed to the Far East out of Seattle, Washington, 22 times. She debarked combat‑ready troops at Yokohama and Sasebo, Japan, and at Pusan and Inchon, South Korea. After the establishment of the uneasy truce 27 July 1953, she cruised primarily to return veterans of the U.N. police action in Korea to the United States.
