World War II Pacific Theatre operations
USS Cahuilla's first service to the U.S. Navy was a brief tour as antisubmarine attack teacher at Norfolk, Virginia. From there she sailed 18 April 1945 towing USS Pegasus (AK-48) for Pearl Harbor. After delivering her tow 24 May, the fleet tug sailed for Guam, where she took a string of pontoon barges in tow for Okinawa.
The end of the war found USS Cahuilla at sea, bound for salvage operations at Eniwetok, from which she returned to take part in the occupation of Nagasaki, Japan, until 16 October. From that time she was based on Okinawa for rescue and tow operations until 14 February 1946.
USS Cahuilla continued to offer towing service to fleet units, and rescue work to naval and merchant ships, calling at Pearl Harbor, Kwajalein, and ports of the west coast and Panama Canal Zone until January 1947.
USS Cahuilla was decommissioned on 27 June 1947 at San Diego, California. Laid up in the Pacific Reserve Fleet, she was struck from the Naval Register and later transferred, under the Security Assistance Program, to Argentina on 9 July 1961.
Renamed ARA Comandante General Irigoyen (A-1), she was in service with the Argentine Navy until 2009.
