USS "Liberty" (AGTR-5) was a "Belmont"-class technical research ship (i.e. electronic spy ship) that was attacked by Israel Defense Forces during the 1967 Six-Day War. She was originally built and served in World War II as a VC2-S-AP3 type Victory cargo ship named SS "Simmons Victory". Her keel was laid down on 23 February 1945, under a Maritime Commission contract at Oregon Shipbuilding Corporation of Portland, Oregon.
