Theenim (AKA-63) was laid down under Maritime Commission contract (MC hull 215) on 3 July 1944 at Kearny, N.J., by the Federal Shipbuilding Co.; launched on 31 October 1944; sponsored by Mrs. Joseph Midder; and commissioned on 22 December 1944, Comdr. G. A. Littlefield, USCG, in command.
On 6 January 1945, Theenim got underway for Hampton Roads, Va., and a brief shakedown in the Chesapeake Bay-Virginia capes area. After loading at Norfolk, the attack cargo ship got underway for the South Pacific on the 27th. The ship proceeded via the Panama Canal and Hawaii to the Solomon Islands, reaching Guadalcanal on 5 March. Assigned to Amphibious Squadron 5, Theenim loaded troops and equipment and headed for the Marianas on 15 March. She sortied from the Saipan staging area on 27 March with Task Group 51.2, Demonstration Group "Charlie," for the assault on Okinawa. Theenim arrived off the Hagushi Beaches on 1 April, but did not land her troops until the 3d, when she began offloading mobile equipment and debarking marines. Three days later, her antiaircraft gunners helped splash an Aichi D3A Type 99 carrier bomber (Val) some 1,000 yards off her stern. On the 12th, her gunners shot down a Mitsubishi A6M Type 00 carrier fighter (Zeke) that passed about 60 feet over her bridge. On the 15th, her guns aided in the destruction of a Nakajima Ki.43 army fighter (Oscar).
The next day, Theenim joined a convoy that was retiring to the Marianas, and she arrived at Saipan on 19 April 1945. On 4 June, she stood put of Tanapag Harbor to return to the Solomons to pick up cargo and carry it to Guam where she arrived on 3 July. For the next three monthsthe last phases of the fighting and the early days of the occupation—the ship shuttled supplies between Saipan, Manus, Guadalcanal, Espiritu Santo, Leyte, Hokkaido, and Honshu. On 5 November, she departed Tokyo Bay for the United States.
Theenim arrived at Portland, Ore., on 17 November 1945 and moved down the coast to San Francisco on 9 December. On 27 December, the ship left the west
coast for the Philippines and arrived
at Subic Bay on 17 January 1946. She
operated in the Philippine Islands until
19 March when she got underway for San Francisco. Upon her arrival on
the west coast, the ship was ordered to report
to the Atlantic Fleet for disposition. She
reached Norfolk on 19 April. Theenim was decommissioned and
returned to the War Shipping Administration on 10 May and was stricken from the Navy list on 12 May 1946.
Renamed American Inventor in 1948 the ship carried on in merchant service under the house flag of the United States Lines, being renamed again, to Pioneer Surf, in 1958. Renamed Australian Surf in 1965, she operated under the flag of Farrell Lines, Inc., into the late 1960s.
Theenim received one battle star for World War II service.
