The USS Artemis (AKA-21) was an Artemis-class attack cargo ship constructed for the United States Navy during World War II. Laid down on 23 November 1943 by Walsh-Kaiser Co., Inc., in Providence, Rhode Island, she was launched on 20 May 1944 and commissioned shortly afterward on 28 August 1944. The vessel measured approximately 426 feet in length, with a beam of around 56 feet, and was powered by two reciprocating steam engines, enabling her to carry a substantial cargo and amphibious assault troops. During her active service from 1944 to 1947, USS Artemis played a vital role in the Pacific Theater. After shakedown training in Boston and transit through the Panama Canal, she transported passengers and supplies to Hawaii, arriving at Pearl Harbor in November 1944. She participated in several training exercises and logistical operations, including the transportation of pontoon equipment and troops. A notable aspect of her service was her involvement in the Battle of Iwo Jima in February 1945, where she anchored off the island and assisted in landing troops and cargo during the initial assault. Throughout the campaign, she remained in the area, discharging troops, cargo, and casualties, contributing to the logistical support essential for the amphibious operation. After the Iwo Jima campaign, Artemis continued to support operations in the Pacific, including resupply missions to Manus, Leyte, and New Guinea. Following Japan's surrender, USS Artemis transported occupation troops to Japan, docking at Yokosuka in October 1945. She operated in Japanese waters until late 1945, then returned to the U.S. West Coast, arriving in San Francisco in December 1945. In 1946, she supported Operation Crossroads at Bikini Atoll, testing atomic bomb effects on warships. She was decommissioned on 10 January 1947 and transferred to the Maritime Administration, eventually being scrapped in 1966. USS Artemis earned two battle stars for her World War II service, reflecting her significant contribution to naval amphibious operations during the war.
