World War II service
Assigned to Service Force, Pacific, Sequatchie departed Galveston on 22 September; transited the Panama Canal at the end of the month, and joined Service Squadron (ServRon) 8 at Pearl Harbor in early November. During that month and in December, she shuttled fuel to Johnston Island and to bases in the Hawaiian Islands. On 31 December, she sailed southwestward to begin duty as a unit of ServRon 10. By mid-January she was in the Marshalls, and on 12 February, she arrived at Saipan, where she discharged cargo during March. At the end of that month, she commenced shuttling fuel to Iwo Jima and continued that duty, alternating it with station ship duty at Saipan, into August.
At the end of the war, Sequatchie was at Saipan where she remained until 26 September, when she returned to Iwo Jima to assume station ship duties there. At the end of November, she returned to Saipan.
The tanker remained in the Central Pacific until ordered back to the United States for inactivation in 1946. In March, she arrived on the U.S. West Coast. At the end of May, she got underway for the Gulf Coast; and, on 26 June, she was decommissioned at New Orleans, Louisiana. Her name was struck from the Navy List on 15 August; and, on 7 October, she was returned to the Maritime Commission and laid up in the National Defense Reserve Fleet at Mobile, Alabama. Final Disposition: fate unknown.
