Technical research ships were used by the U.S. Navy during the 1960s to gather intelligence by monitoring the electronic communications of nations in various parts of the world. At the time these ships were active, the mission of the ships was covert and discussion of the true mission was prohibited ("classified information"). The mission of the ships was publicly given as conducting research into atmospheric and communications phenomena. However, the true mission was more or less an open secret and the ships were commonly referred to as "spy ships". The United States Navy (USN) is the branch of the United States armed forces responsible for naval operations. ...
The 1960s decade refers to the years from 1960 to 1969, inclusive. ...
These ships carried a crew of U.S. Navy personnel whose specialty was intercepting electronic communications and gathering intelligence from those communications (see SIGINT, COMINT, ELINT). In the 1960s those personnel had a U.S. Navy rating of Communications Technician, or CT. SIGINT stands for SIGnals INTelligence, which is intelligence-gathering by interception of signals, whether by radio interception or other means. ...
SIGINT stands for SIGnals INTelligence, which is intelligence-gathering by interception of signals, whether by radio interception or other means. ...
ELINT stands for ELectronic INTelligence, and refers to intelligence-gathering by use of electronic sensors. ...
The term rating or rate carries different meanings depending on which navy is being discussed. ...
In order to transmit intelligence information that had been gathered back to United States for further processing and analysis, these ships had a special system named Technical Research Ship Special Communications, or TRSSCOM (pronounced tress-com). The system used a special gyro-stabilized 16-foot dish antenna, which can be seen aft of the main superstructure in the accompanying photographs of the Belmont and Liberty. Radio signals were transmitted toward the moon, where the signals would bounce back toward the Earth and be received by a large 64-foot dish at the Naval Communications Station in Washington, D.C. Communications could occur only when the moon was visible simultaneously at the ship's location and in Washington. The gyro stabilization of the antenna kept the antenna pointed at the moon while the ship rolled and pitched on the surface of the ocean.

These ships were classified as naval auxiliaries with a hull designation of AGTR, which stands for Auxiliary, General, Technical Research. Five of these ships were built with hull numbers of 1–5. The first three ships of this type (Oxford, Georgetown, and Jamestown) were converted from World War II-era Liberty ships. The last two ships (Belmont and Liberty) were converted from Victory ships. All of the technical research ships were decommissioned and stricken by 1970. The United States Navy uses hull classification symbols (sometimes called hull codes) to identify the types of its ships. ...
The Liberty ships were cargo ships built in the United States during World War II. They were cheap and quick to build, and came to symbolize U.S. wartime industrial output. ...
The Victory ship was a type of cargo ship produced in large numbers by North American shipyards during World War II to replace losses caused by German submarines. ...
The most well known of these ships was the USS Liberty, which was attacked and severely damaged by Israeli aircraft and ships in the Mediterranean on June 8, 1967, resulting in the deaths of 34 US sailors.

There were also three similar but smaller ships of a different type but with a similar mission. Those ships were "environmental research" ships, of type AGER. The most well known of those ships was the USS Pueblo (AGER-2), which was attacked and captured by North Korea on January 23, 1968. USS Pueblo (AGER-2) USS Pueblo, AGER-2 is a United States ship, famous for being boarded and captured by soldiers of North Korea in 1968 in what is known as the Pueblo incident. ...
