The ship was launched on 12 September 1943 by the Western Pipe and Steel Company, San Francisco, California; sponsored by Mrs. Sue Frances Hemminger, widow; and commissioned on 30 May 1944.

On 28 February 1945 while on a HUK mission with Corregidor (CVE-58) and CortDiv 53, the destroyer escort was diverted to participate in the fruitless search for Lieutenant General Millard F. Harmon, Commander Army Air Forces Pacific, whose plane had disappeared.

From 16 May to 20 June, she acted as screen for a carrier group engaged in neutralization of Sakishima Gunto and supported ground forces on Okinawa, as well as the air attack on Kyūshū.

Detached from the Pacific Fleet, Hemminger reached Norfolk, Virginia, on 2 December via Saipan, Pearl Harbor, San Diego, California, and the Panama Canal.

One reserve cruise in June 1952 took Hemminger to Lisbon, Portugal, while others saw her at Rouen, France; Barranquilla, Colombia; Cadiz, Spain, and New Orleans, Louisiana.
