USNS Watertown (T-AGM-6) was a Watertown-class missile range instrumentation ship acquired by the United States Navy in 1960 and converted from her SS Niantic Victory Victory ship cargo configuration to a missile tracking ship, a role she retained for eleven years before being placed out of service in 1971.
The Western Range (WR) is the space launch range that supports the major launch head at Vandenberg Space Force Base. Managed by the Space Launch Delta 30, the WR extends from the West Coast of the United States to 90° East longitude in the Indian Ocean where it meets the Eastern Range Operations involve military, government, and commercial interests. The WR has been operated by civilian contractors since its establishment, following the precedent of the Eastern Range. On 1 October 2003, InDyne Inc. took over the range contract from ITT Industries which had operated the range for the previous 44 years.
USNS Observation Island (T-AGM-23) was built as the Mariner-class merchant ship Empire State Mariner for the United States Maritime Commission, launched 15 August 1953, and operated by United States Lines upon delivery on 24 February 1954, making voyages for the Military Sea Transportation Service (MSTS) until going into reserve at Mobile, Alabama on 9 November 1954.
A tracking ship, also called a missile range instrumentation ship or range ship, is a ship equipped with antennas and electronics to support the launching and tracking of missiles and rockets. Since many missile ranges launch over ocean areas for safety reasons, range ships are used to extend the range of shore-based tracking facilities.
USNS Invincible (T-AGM-24), also known as ex-AGOS 10, is one of two tracking ships operated by the Military Sealift Command. One of the radars it carries is the Cobra Gemini dual band, X band and S band, radar.
The Eastern Range (ER) is an American rocket range (Spaceport) that supports missile and rocket launches from the two major launch heads located at Cape Canaveral Space Force Station and the Kennedy Space Center (KSC), Florida. The range has also supported Ariane launches from the Guiana Space Centre as well as launches from the Wallops Flight Facility and other lead ranges. The range also uses instrumentation operated by NASA at Wallops and KSC.
The Downrange Anti-missile Measurement Program or DAMP was an applied research project to obtain scientific data, just prior to and during re-entry, on intermediate- and intercontinental-range ballistic missiles as they returned to earth. The program was funded by the Advanced Research Projects Agency (ARPA) under the technical direction of the Army Ordnance Missile Command (AOMC) during the period 1 January 1959 through 30 September 1963.
USAS American Mariner was a United States Army research vessel from January 1959 to 30 September 1963. She was originally assigned to the DAMP Project by the Advanced Research Projects Agency (ARPA) to attempt to collect radar signature data on incoming intercontinental ballistic missiles in the Caribbean, the South Atlantic Ocean, and the Indian Ocean. Her initial operations involved providing radar track on the Atlas missile, which was under development at the time. Subsequently, she provided track on other types of missiles as they proceeded through their development and operational stages. In September 1963 the original contract was transferred to the USAF until the completion of the testing phase in 1964.
The Missile Test Project (MTP) was a U.S. Air Force program operated by RCA Service Company (RCAS) from Patrick Air Force Base, Florida, under the direction of prime contractor Pan American Guided Missiles Research Division during the 1950s and continuing on for several more decades. Under this program, RCAS instrumented and operated various ships and stations on the Air Force Eastern Test Range with electronic tracking and telemetry equipment. The instrumented ships and stations tracked incoming intercontinental ballistic missiles launched from Cape Canaveral Air Force Station (CCAFS) and, using radar or telemetry, also tracked manned or unmanned space vehicles orbiting the earth.
SS Twin Falls Victory, named after Twin Falls, Idaho, was a Victory ship built for World War II. Converted to a Missile Range Instrumentation Ship, she was initially operated by the US Air Force as USAF Twin Falls Victory, before coming under US Navy control and being named USNS Twin Falls (T-AGM-11/T-AGS-37). She later had a third career as the training ship SS John W. Brown II.
Pan American Airways Guided Missile Range Division was a distinct division of Pan American World Airways in the period 1950-1980, responsible as prime contractor of the U.S. Air Force Eastern Test Range, based out of Patrick Air Force Base, Florida. It was responsible for providing operations and maintenance for the Eastern Test Range, but subcontracted operation and maintenance of electronic equipment, such as missile tracking radars on the test range tracking ships and stations to the Missile Test Project of RCA Service Company (RCAS).
USNS General Hoyt S. Vandenberg (T-AGM-10) was a General G. O. Squier-class transport ship in the United States Navy in World War II named in honor of U.S. Army Chief of Engineers Harry Taylor. She served for a time as army transport USAT General Harry Taylor, and was reacquired by the navy in 1950 as USNS General Harry Taylor (T-AP-145).
USNS Range Recoverer (T-AG-161/T-AGM-2/YFRT-524) was a missile range instrumentation ship responsible for providing radar and/or telemetry track data on missiles launched from American launch sites.
SS Haiti Victory (T-AGM-238) was originally built and operated as Greenville class cargo Victory ship which operated as a cargo carrier in both the Atlantic Ocean and the Pacific Ocean during World War II.
USNS Sword Knot (T-AGM-13) was a missile range instrumentation ship which operated as USAFS Sword Knot on the United States Air Force's Eastern Range during the late 1950s and early 1960s. Sword Knot operated under an Air Force contract with Pan American Airways Guided Missile Range Division headquartered in Cocoa Beach, Florida.
USNS Rose Knot (T-AGM-14) was a World War II era United States Maritime Commission small cargo ship built in 1945 and delivered to the War Shipping Administration for operation through agent shipping companies and for periods by the Military Sea Transportation Service (MSTS). In 1957 the ship was transferred to the Air Force and converted into a missile range instrumentation ship which operated as USAFS Rose Knot on the U.S. Air Force's Eastern Test Range during the late 1950s and early 1960s. Rose Knot operated under an Air Force contract with Pan American Airways Guided Missile Range Division headquartered in Cocoa Beach, Florida. In July 1964, all Air Force tracking ships were transferred to MSTS for operation with the Air Force in operational control while the ships were at sea as tracking ships. Rose Knot had special facilities for supporting the human spaceflight program and supported the early crewed flights. The ship was owned by the U.S. government until sold for non-transportation use in 1977.
USNS Coastal Crusader (AK-220/ORV-16/T-AGM-16/AGS-36) was an Alamosa-class cargo ship that was constructed for the US Navy during the closing period of World War II. She was later acquired by the US Army in 1946 and the US Air Force in 1957 before being reacquired by the USN in 1964 and as a missile range instrumentation ship.
USNS Timber Hitch (T-AGM-17) was a US Navy missile range instrumentation ship which earlier operated as the US Air Force Ocean Range VesselUSAFS Timber Hitch (ORV-17) on the US Air Force's Eastern Test Range during the late 1950s and early 1960s. Timber Hitch operated under an Air Force contract with Pan American Airways Guided Missile Range Division headquartered in Cocoa Beach, Florida.
USNS Waters (T-AGS-45) is a United States Navy vessel tasked with supporting submarine navigation-system testing and providing ballistic missile flight test support services. In 2011, it was homeported in Port Canaveral, Florida.
