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

A United States Coast and Geodetic Survey diagram of ca. 1920 of wire-drag hydrographic survey operations as carried out by Hilgard and her sister ship USC&GS Wainwright (ASV 83). The basic principle is to drag a wire attached to two vessels; if the wire encounters an obstruction it will come taut and form a "V."

Hilgard and her sister ship USC&GS Wainwright (ASV 83) 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).
