Wainwright was built as an "auxiliary survey vessel" (ASV) for the Coast and Geodetic Survey by Robinson Marine at Benton Harbor, Michigan, in 1942.

Wainwright and her sister ship USC&GS Hilgard (ASV 82) conducted wire-drag hydrographic survey operations together along the United States East Coast until 1967, when they were replaced by USC&GS Rude (ASV 90), which later became NOAAS Rude (S 590), and USC&GS Heck (ASV 91), which later became NOAAS Heck (S 591).
