The USS Belmont (AGTR-4/AG-167) was a converted Victory cargo ship with a significant service history as a Cold War-era electronic research vessel. Originally built during World War II, she was launched as SS Iran Victory on 25 March 1944 by the Oregon Shipbuilding Corporation in Portland, Oregon. She measured approximately 7,608 gross register tons with an overall length of 439.1 feet (133.8 meters), a beam of 62.1 feet (18.9 meters), and a depth of 34.5 feet (10.5 meters). Powered by twin Westinghouse oil-fired steam turbines producing 8,500 horsepower, she could reach speeds of up to 17 knots. Initially serving as a merchant cargo ship, Iran Victory participated in wartime logistics, including delivering ammunition and other supplies in the Pacific theater, notably during the Philippines campaign and the Battle of Ulithi. She supported U.S. military operations by transporting essential materials such as ammunition, mail, and food, and was present when the USS Randolph was hit by a Kamikaze attack at Ulithi Atoll in 1945. After the war, she supported Korean War efforts by moving supplies to the conflict zone. In 1963, the ship was acquired by the U.S. Navy, converted at the Willamette Iron and Steel Co. yard in Portland into a specialized electronic intelligence platform, and renamed USS Belmont on 8 June 1963. She was redesignated AGTR-4 on 1 April 1964 and commissioned at Puget Sound Naval Shipyard on 2 November 1964. As a Belmont-class technical research ship, she was tasked with conducting electromagnetic propagation research, supporting Cold War espionage efforts. Belmont’s operational history included deployments to the West Indies, South America, Africa, and the Mediterranean, where she engaged in signals intelligence and surveillance activities, often near sensitive geopolitical hotspots. Her voyages included circumnavigating South America and operating along African coasts, as well as a notable tour with the U.S. 6th Fleet in the Mediterranean in 1969. Deemed of limited naval value, Belmont was decommissioned on 16 January 1970 and sold for scrapping in June 1970. Her service underscored the transition of merchant ships into vital intelligence platforms during the Cold War, marking her as a significant, if lesser-known, component of U.S. maritime and intelligence history.
