About this Unit
USS Jamestown (AGTR-3) was a technical research ship of the United States Navy, commissioned in 1963. Originally built as a Liberty ship during World War II, she was later converted for electronic intelligence gathering during the Cold War. Serving primarily in the Pacific, Jamestown monitored communications and electronic signals, supporting U.S. intelligence operations during the Vietnam War. She was decommissioned in 1969 and subsequently struck from the Naval Vessel Register.
Historical Facts
•
Converted Liberty Ship: USS Jamestown (AGTR-3) began her life as the Liberty Ship J. Howland Gardner, built in 1945 for World War II cargo service before her conversion into an intelligence-gathering vessel.
•
Special Mission: The ship was converted to an Auxiliary General Technical Research Ship (AGTR) in the early 1960s, tasked with conducting signals intelligence (SIGINT) operations during the Cold War.
•
Nickname - "Spook Ship": Due to her secretive missions and intelligence-gathering role, Jamestown was often nicknamed a "spook ship" by those in the know.
•
Vietnam War Service: USS Jamestown conducted several intelligence-gathering patrols in the South China Sea and Gulf of Tonkin during the Vietnam War, supporting U.S. military operations.
•
Highly Classified Missions: The ship's true missions were often classified, with much of her crew sworn to secrecy about their activities even decades later.
•
International Incidents: Like other "research" ships of her kind, Jamestown operated close to foreign coasts, sometimes provoking diplomatic protests or shadowing by hostile navies.
•
Technological Upgrades: Over her career, Jamestown was fitted with advanced electronic surveillance equipment, including antennas and listening devices, making her a floating signals intelligence platform.
•
Crew Composition: The ship carried a blended crew of Navy personnel as well as specialists from the National Security Agency and other government agencies.
•
Decommissioning: USS Jamestown was decommissioned in 1969 after just a few years of service as an AGTR, reflecting the rapid technological evolution in signals intelligence.
•
Final Fate: After decommissioning, the ship was struck from the Naval Vessel Register and sold for scrap in 1970, ending her unique chapter in Cold War naval history.
