Following another tour as fuel station ship at Hvalfjörður (30 May–26 June), Chemung departed from New York City 20 August with a convoy bound for the United Kingdom.

Recommissioned 1 December 1950, Chemung steamed to the Far East 28 January 1951 for a brief tour refueling forces engaged in the Korean War.

During her second tour of duty (7 July 1951—20 April 1952), she supported United Nations troops in Korea, served on the Formosa Patrol, then transported oil from Ras Tanura, Arabia, to Guam.

She again sailed from San Pedro 24 June 1952 to support the US 7th Fleet off Korea until returning to Mare Island for overhaul on 24 February.

In nine succeeding tours of duty in the Western Pacific from her home port at San Pedro California between 1953 and 1960, Chemung supported many of the 7th Fleet's most notable contributions to the keeping of peace in the Far East.
