The USS Troilus (AKA-46) was an Artemis-class attack cargo ship constructed during the final months of World War II, primarily designed for amphibious operations. Laid down on 18 March 1945 by the Walsh-Kaiser Co., Inc. in Providence, Rhode Island, and launched on 11 May 1945, the vessel was sponsored by Mrs. Arthur G. B. Metcalf. She was commissioned into the U.S. Navy on 8 June 1945, shortly before the end of the war. The ship measured approximately 426 feet in length with a beam of about 59 feet, designed to carry troops, cargo, and landing craft for amphibious assaults. Her service began with shakedown training in Chesapeake Bay before departing Norfolk on 11 July 1945, heading through the Panama Canal to Hawaii. At Pearl Harbor, she conducted amphibious exercises with Transport Squadron 22 until the surrender of Japan on 15 August 1945, after which she shifted focus to logistical support for occupation efforts in Japan. Troilus played a vital role in delivering supplies, ammunition, vehicles, and troops to Japan, notably unloading cargo in Wakayama harbor amid challenging weather conditions. She also transported over 200 troops from the 98th Division’s 368th Field Artillery. After completing her mission in Japan, she returned to the Philippines, stopping at several key ports including Subic Bay, Manila Bay, and Lingayen Gulf, before disembarking troops at Wakayama and Nagoya. In November 1945, Troilus was assigned to Operation "Magic Carpet," repatriating American servicemen from the Pacific. She brought back 485 passengers to San Francisco by late November. Subsequently, she made additional voyages to Japan and the U.S. West Coast, transporting landing craft and cargo. Her final voyage was in April 1946, after which she was decommissioned on 14 June 1946. The vessel was struck from the Navy list in July and transferred to the War Shipping Administration. She remained laid up until 1967 when she was sold for scrap, marking the end of her brief but active service.
