The USS Virgo (AKA-20) was an Andromeda-class attack cargo ship constructed during World War II, later converted into an ammunition ship designated AE-30. Built by the Federal Shipbuilding and Drydock Company at Kearny, New Jersey, she was laid down on 9 March 1943, launched on 4 June 1943, and commissioned at the New York Navy Yard on 16 July 1943. Designed for amphibious assault operations, Virgo was a medium-sized vessel divided into five holds, each equipped with multiple booms—two thirty-ton and one or two ten-ton booms—providing a cargo capacity of approximately 350,000 cubic feet after conversion. Her propulsion system consisted of a single steam turbine engine rated at 6,000 horsepower, driving a single screw propeller, capable of reaching a top speed of 17 knots and cruising comfortably at 15.5 knots. She carried 436,000 gallons of fuel oil, enabling a range of over 10,000 miles at cruising speed. Her auxiliary systems included two General Electric 300 KW generators and one Ideal Electric 300 KW generator, with additional emergency power arrangements. Virgo’s service history spans over 22 years, beginning with her participation in key Pacific campaigns during World War II. She was present at Tarawa, participated in the Gilbert and Marshall Islands invasions, and supported landings at Saipan, Peleliu, and Okinawa, earning seven battle stars for her WWII service. Post-war, she supported occupation duties in Japan and China, and from 1949 onwards, she primarily operated in the Far East, supplying bases and supporting U.S. military operations during the Korean and Vietnam wars. During the Korean War, Virgo provisioned ships and troops at Inchon, Jinsen, and other Korean ports, earning nine battle stars. In 1965, she was reclassified as an ammunition ship (AE-30) and recommissioned. She supported Vietnam War operations, supplying ammunition to naval forces in the Gulf of Tonkin and off the Vietnamese coast, earning ten additional battle stars. Decommissioned in 1971, she was transferred to the Maritime Administration and eventually sold for scrapping in 1973. Her significance lies in her versatile service, from amphibious assaults to logistical support in multiple conflicts, embodying the evolution of naval auxiliary vessels through mid-20th century warfare.
