The second Osage was named "for an old monitor formerly in the Navy."
(LSV3: displacement 4,626; length 458: beam 60; draft 20; speed 21 knots; complement 472; troops 1,358; armament 2 5, 8 40 millimeter, 20 20 millimeter; class Osage)
The second Osage (AN3) was laid down on 1 June 1942 at Pasacagoula, Miss., by the Ingalls Shipbuilding Corporation; redesignated as a transport, AP108, on 1 May 1943; launched on 1 December 1943; sponsored by Mrs. Dorothy K. McHenry ("a charming young matron"), wife of Lt. John A. McHenry, Officer in Charge of Construction (for both U.S. Navy and Maritime Commission vessels), Pascagoula; redesignated as a vehicle landing ship, LSV3, 21 April 1944; and commissioned alongside Outfitting Dock No.2, Tampa (Fla.) Shipbuilding Co., on 30 December 1944, Capt. Harry H. Keith in command.
Following shakedown out of Galveston, Tex., Osage embarked 703 officers and men of Casual Draft 2610 of the 126th Naval Construction Battalion and loaded 29 amphibian trucks (DUKW) at New Orleans. Transiting the Panama Canal on 8 February 1945, she continued on to Pearl Harbor for further amphibious training, conducted off Maui. On 17 March she sailed with vehicles and various units of the10th Army units embarked, in company with attack transport Lauderdale (APA179) and the submarine chasers PC492 and PC594. At Ulithi she joined Task Force 51 and continued on to Okinawa, arriving on 11 April. Despite repeated enemy air attacks, during which she frequently interrupted unloading operations to go to general quarters, laying smoke each night and opening fire as necessary to drive off Japanese planes when in range, Osage completed offloading within five days and on the 16th sailed for Saipan for provisioning, proceeding in company with Montauk (LSV6).
Moving thence to Peleliu, in the Palaus, she reached that place on 28 April 1945. She stood out the following day for Guam, Marianas Islands, and steamed unaccompanied, loaded with tank landing vehicles (LVT) of the 726th Amphibious Tractor Battalion, and marines of the 4th Anti-Aircraft Battalion, USMC. Reaching her destination on 1 May, Osage unloaded trucks and disembarked troops, and after fueling and provisioning sailed from Apra Harbor to return to Saipan, arriving on 4 May, where she launched the remaining vehicles via her stern ramp, and began a period of post-voyage repairs to her main and auxiliary engines. For a little over a month, Osage awaited orders at Saipan, painting ship and conducting inspections and training, after which time she received orders to proceed to Noumea, New Caledonia. Sailing on 6 June, the ship crossed the equator on 10 June at approximately 164º0' E, observing the event with appropriate ceremonies, during which time some 400 "pollywogs" received initiation into the realm of King Neptune.
Arriving at her destination on 15 June 1945, Osage received engine repairs at Noumea, culminating in trials on 25 June, then embarked the men and loaded the vehicles and equipment of the 47th Naval Construction Battalion, taking departure for Guam on 6 July. Unloaded and ready for sea four days later, she departed Guam on 11 July, and after a brief pause at Saipan to load supplies, pushed on for San Francisco, reaching her destination on 25 July for voyage repairs at the Kaiser yard at Richmond. During that period of yard work, that coincided with the cessation of hostilities with Japan, she received repairs to her engines, a drydocking, general repairs, and a revision of her paint scheme from "green and black camouflage to over-all gray." She was ultimately reported "ready for sea" on 22 August.
Five days later, on 27 August 1945, with approximately 1,400 officers and enlisted men (U.S. Army) embarked, replacements for troops in the forward areas, Osage sailed for Ulithi, in the Western Carolines, arriving there on 10 September where she refueled, then continued her voyage to the Philippines, reaching Tacloban two days later to disembark almost half of her embarked soldiers. Underway thence for Manila on 14 September, the ship reached her destination two days later to disembark the balance of her passengers. Sailing on 21 September with nine officers and 496 enlisted infantry, field artillery, engineering, signal, quartermaster and chemical warfare division passengers, she reached Batangas later the same day, where she loaded 61 army vehicles.
Having completed her work in the Philippines, Osage sailed for Japan in company with the attack cargo ship Betelgeuse (AKA11) and attack transport Oconto (APA107), the trio later joining with Task Group 34.8 to comprise a convoy of 23 ships and two escorts. The ship arrived in Tokyo Bay on 3 October, to discharge her passengers and cargo at Yokohama. Ordered thence to perform Magic Carpet duty, transporting veterans back to the United States, Osage sailed for Okinawa on 7 October. Receiving typhoon warnings while en route, the ship steered courses and speeds designed to evade the bad weather, and stood in to Buckner Bay on 11 October, where she embarked some 75 officers and over 1,600 enlisted men on 13 October for transportation to San Francisco and release from the naval service. She sailed for the west coast the same day.
Osage arrived at her destination on 26 October 1945, but would soon be underway on a return voyage to the Far East on 10 November. Calling first at Shanghai, China, and then Buckner Bay, the ship returned to the west coast immediately thereafter. Then, following a period of repairs at Portland that ended in mid-January 1946, the ship remained at San Pedro until 1 May, when she sailed for Panama. Although she had been earmarked for conversion to a net cargo ship, she remained a vehicle cargo ship due to the selection of Montauk for the change. After transiting the Panama Canal (9-12 May), Osage shed her port propeller on 12 May. She then put in to New Orleans (16 May-9 June), then moved to Mobile for overhaul, the availability of funds dictating when urgent repairs could be accomplished. Osage was towed to Orange, Tex., by ATA199, where she was inactivated, placed "out of commission, in reserve" on 16 May 1947.
Redesignated as a mine warfare command and support ship, MCS3, effective 18 October 1956, Osage remained in reserve until delivered to the custody of the National Defense Reserve Fleet at Beaumont, Texas, on 19 September 1960. Stricken from the Naval Vessel Register on 1 September 1961, the ship was delivered to the Maritime Adminstration, on permanent transfer, on 1 September 1962. Returned to the Navy for stripping on 8 November 1972 incident to her future disposal, she was returned to the Maritime Administration on 27 November 1973. Sold to Luria Brothers and Co., Inc., Cleveland, Ohio, on 11 December 1974, the ship was delivered to her purchasers on 6 January 1975, to be broken up.
Osage received one battle star for service in World War II.
