World War II Pacific operations

Departing San Francisco, California, 12 September 1942, Delphinus arrived at Auckland, New Zealand, 4 October. She operated from this base until the end of 1945, carrying chilled and frozen provisions to forward bases in the South Pacific and to the Society, Fiji, and Samoan Islands.

After calling at Manila in January 1946, Delphinus sailed for the west coast, arriving at San Francisco, California, 23 February. For a brief period she carried cargo along the west coast and to Pearl Harbor, then sailed to New Orleans, Louisiana.

End-of-War Decommissioning

Delphinus was decommissioned on 8 May 1946 in New Orleans, and was delivered to the War Shipping Administration the same day.
