The USS Liberty (AGTR-5) was a Belmont-class technical research vessel originally built during World War II as a VC2-S-AP3 type Victory cargo ship named SS Simmons Victory. The keel was laid on February 23, 1945, at Oregon Shipbuilding Corporation in Portland, Oregon. She was launched and delivered to the War Shipping Administration on May 4, 1945, and shortly thereafter transferred to the Coastwise-Pacific Far East Line, designated as a "Fleet Issue Ship." Her primary wartime role involved delivering ammunition from the San Francisco-Suisun Bay area navy munitions depot for operations such as the planned invasion of Japan. Constructed as a Victory cargo ship, Simmons Victory was equipped with a 5-inch gun, a 3-inch gun, and 20-mm anti-aircraft weapons, manned by a Navy Armed Guard detachment. She supported U.S. military operations during World War II, including trips to the Philippines and the support of Operation Downfall, arriving in Leyte Gulf just before Japan’s surrender in August 1945. Following the war, she transitioned between commercial charters and the National Defense Reserve Fleet, making nine trips to the Far East during the Korean War to support American troops. In 1963, the vessel was acquired by the U.S. Navy and converted into a "Miscellaneous Auxiliary" ship at Portland’s Willamette Iron and Steel, receiving the new designation USS Liberty (AG-168). She was further reclassified as a Technical Research Ship (AGTR-5) in 1964 and commissioned in December of that year at Puget Sound Naval Shipyard. The ship was outfitted in 1965 at Norfolk, Virginia, with advanced electronic intelligence capabilities to support NSA operations. Liberty’s maritime significance is marked by her role in electronic espionage and her involvement in the 1967 Six-Day War, when she was attacked by Israeli forces in international waters. The attack resulted in 34 fatalities, 174 wounded, and severe damage to the vessel, including a large hole amidships and a twisted keel. Despite her damage, she remained afloat and was repaired temporarily before returning to the U.S. in July 1967. She was decommissioned in June 1968 and sold for scrap in 1973. Her service and the attack remain notable in U.S. naval and intelligence history, with her crew receiving numerous decorations for their heroism.
