USS Cetus (AK-77)

The USS Cetus (AK-77) was a Crater-class cargo ship in the service of the United States Navy in World War II. Named after the equatorial constellation Cetus, it was the only ship of the Navy to bear this name.

Cetus was laid down 21 November 1942 as liberty ship SS George B. Cortelyou (MCE hull 445) by Permanente Metals Corporation, Yard No. 2, Richmond, California, under a Maritime Commission contract; launched 26 December 1942; sponsored by Mrs. N. F. Potter; acquired by the Navy 4 January 1943; and commissioned 17 January 1943, Lieutenant Commander N. T. Gansa, USNR, in command.

Cetus’s assignment, for which she sailed from San Francisco 1 February 1943, was carrying cargo among South Pacific bases, and from ports in New Zealand. She arrived at Espiritu Santo, New Hebrides, 24 February, and began her share of the buildup of Solomon and Society Islands bases from which naval forces fought north through the Bismarcks. On 12 July 1944, she sailed from Guadalcanal for Eniwetok, where she prepared for her support of the invasion of Guam. She put to sea again 23 July, and arrived off Guam 27 July, 6 days after the initial assault. With bitter fighting continuing ashore, Cetus offloaded her much needed cargo over reefs and beaches, then returned to the South Pacific.

In September and October 1944, Cetus brought cargo, some of which eventually played its part in the liberation of the Philippines, from Espiritu Santo to Ulithi and Manus. Cetus lay just outside Manus Harbor 10 November when ammunition ship Mount Hood (AE-11) exploded, but escaped injury. She returned to Auckland and Wellington, New Zealand, to load cargo after brief overhaul, and on 18 March 1945 arrived at Guam to aid in preparations for the invasion of Okinawa, carrying cargo to Saipan, and then to Ulithi. On 26 April she herself arrived off Okinawa, with cargo to support the determined fighting ashore. Cetus unloaded under the constant hazard of enemy air and surface suicide attack, but received no injury. She then sailed for San Francisco, arriving on 12 June for a major overhaul which kept her there until after the close of the war. She proceeded on to Norfolk, Virginia, where she was decommissioned 20 November 1945, and returned to the Maritime Commission the following day. Cetus was scrapped in 1972.

Cetus received two battle stars for World War II service.
