Sequatchie (ex-Royston) was laid down on 1 June 1943 by Todd-Galveston Dry Dock Inc., Galveston, Texas, under Maritime Commission contract (MC hull 790); launched on 21 December 1943; sponsored by Mrs. Hazel Tometich; delivered on 5 August 1944, and commissioned on 2 September 1944.

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.

The tanker remained in the Central Pacific until ordered back to the United States for inactivation in 1946.

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.
