The Sound Surveillance System (SOSUS) was a submarine detection system based on passive sonar developed by the United States Navy to track Soviet submarines. The system's true nature was classified with the name and acronym SOSUS themselves classified. The unclassified name Project Caesar was used to cover the installation of the system and a cover story developed regarding the shore stations, identified only as a Naval Facility (NAVFAC), being for oceanographic research. In 1985, as the fixed bottom arrays were supplemented by the mobile Surveillance Towed Array Sensor System (SURTASS) and other new systems were coming on line, the name itself changed to Integrated Undersea Surveillance System (IUSS). The commands and personnel were covered by the "oceanographic" term until 1991 when the mission was declassified. As a result, the commands, Oceanographic System Atlantic and Oceanographic System Pacific became Undersea Surveillance Atlantic and Undersea Surveillance Pacific, and personnel were able to wear insignia reflecting the mission.
USNS Kingsport (T-AG-164) was built as SS Kingsport Victory, a United States Maritime Commission VC2-S-AP3 (Victory) type cargo ship. During the closing days of World War II the ship was operated by the American Hawaiian Steamship Company under an agreement with the War Shipping Administration. After a period of layup the ship was operated as USAT Kingsport Victory by the Army under bareboat charter effective 8 July 1948. When Army transports were transferred to the Navy's Military Sea Transportation Service the ship continued as USNS Kingsport Victory (T-AK-239), a cargo transport. On 14 November 1961, after conversion into the first satellite communication ship, the ship was renamed Kingsport, reclassified as a general auxiliary, and operated as USNS Kingsport (T-AG-164).
USNS Mizar (MA-48/T-AGOR-11/T-AK-272) was a vessel of the United States Navy. She was named after the star Mizar.
R/P FLIP is an open ocean research platform owned by the U.S. Office of Naval Research (ONR) and operated by Scripps Institution of Oceanography. The platform is 108 meters (355 ft) long and is designed to partially flood and pitch backward 90°, resulting in only the front 17 meters (55 ft) of the platform pointing up out of the water, with bulkheads becoming decks. When flipped, most of the ballast for the platform is provided by water at depths below the influence of surface waves, hence FLIP is stable and mostly immune to wave action similar to a spar buoy. At the end of a mission, compressed air is pumped into the ballast tanks in the flooded section and the platform, which has no propulsion, returns to its horizontal position so it can be towed to a new location. The platform is frequently mistaken for a capsized ocean transport ship.
R/V Thomas G. Thompson (AGOR-23), an oceanographic research vessel and lead ship of her class, is owned by the United States Office of Naval Research and operated under a bareboat charterparty agreement by the University of Washington as part of the University-National Oceanographic Laboratory System (UNOLS) fleet.
The Naval Oceanographic Office (NAVOCEANO), located at John C. Stennis Space Center in south Mississippi, comprises approximately 1,000 civilian, military and contract personnel responsible for providing oceanographic products and services to all elements within the Department of Defense.
The Pathfinder-class survey ships are owned by the United States Navy and operated by Military Sealift Command for the Naval Oceanographic Office ("NAVOCEANO"). They have mostly civilian crews, including scientists from NAVOCEANO.
USCGC Yamacraw (WARC-333) was a United States Coast Guard Cable Repair Ship. The ship was built for the Army Mine Planter Service as U. S. Army Mine Planter Maj. Gen. Arthur Murray (MP-9) delivered December 1942. On 2 January 1945 the ship was acquired by the Navy, converted to an Auxiliary Minelayer and commissioned USS Trapper (ACM-9) on 15 March 1945. Trapper was headed to the Pacific when Japan surrendered. After work in Japanese waters the ship headed for San Francisco arriving there 2 May 1946 for transfer to the Coast Guard.
USS Chain (ARS-20/T-AGOR-17) was a Diver-class rescue and salvage ship commissioned by the U.S. Navy during World War II. Her task was to come to the aid of stricken vessels.
RV Sir Horace Lamb was a Navy owned former mine warfare vessel assigned to the Columbia University, Geophysical Field Station research facility in Bermuda for acoustic research operating from 1959 to 1976. The ship was the former USS Redpoll (AMS-57/YMS-294), a YMS-1-class minesweeper of the YMS-135 subclass built and commissioned as YMS-294 in 1943.
USS Hunting (E-AG-398) was built as the LSM-1-class landing ship medium LSM-398 at the Charleston Navy Yard and launched in the first week of 1945. After service in the Atlantic as a landing ship the vessel was converted in 1953 to a sonar research vessel for the Naval Research Laboratory. Hunting was unique among Navy research vessels of the time in having a center well through which large towed "fish" could be transported and lowered to operating depths. The work contributed to sonar improvements and understanding ocean acoustics.
USNS James M. Gilliss (T-AGOR-4) was a Robert D. Conrad-class oceanographic research ship acquired by the U.S. Navy in 1962. The ship was operated by the Military Sea Transportation Service and managed by the Naval Oceanographic Office as one of the "Navy Pool" vessels serving various Navy laboratories and projects in the Atlantic Ocean. After active Navy pool service the ship was assigned to the University of Miami to operate as part of the University-National Oceanographic Laboratory System (UNOLS) fleet until 1979.
USNS Sands (T-AGOR-6) was a Robert D. Conrad-class oceanographic research ship operated by the Military Sealift Command (MSC) for the Naval Oceanographic Office from 1965 to 1973. During that period she provided ocean-bottom information and underwater test data to the U.S. Navy and other U.S. agencies. The ship was the second naval vessel to be named for Rear Admiral Benjamin F. Sands and his son Rear Admiral James H. Sands, the first being the destroyer Sands (DD-243). The ship operated in the Atlantic on oceanographic and geophysical assignments for the Oceanographic Office and other agencies.
Thomas Washington (T-AGOR-10) was a Robert D. Conrad-class oceanographic research ship delivered to the U.S. Navy in 1965. The ship was owned by the Navy but assigned to the Scripps Institute of Oceanography, University of California, La Jolla, California and operated as R/VThomas Washington from delivery to inactivation.

Bartlett was one of the ships under the technical direction of the Naval Oceanographic Office (NAVOCEANO) operating as an Auxiliary General Oceanographic Research (AGOR) program "pool" ship for support of Navy laboratories on each coast as well as NAVOCEANO projects. The ship was first assigned to support laboratories on the West Coast with last operations in similar support on the East Coast and Atlantic.
Gyre (T-AGOR-21), best known as RV Gyre, was the lead ship of her class of oceanographic research ships acquired by the U.S. Navy in 1973 for assignment to the University-National Oceanographic Laboratory System (UNOLS) fleet of Navy owned ships. Gyre was operated by the Texas A&M University School of Oceanography as part of the Navy owned UNOLS fleet until stricken 17 August 1992 and transferred to the university under a program transferring ships to states, schools and other public institutions. The university operated the ship until sale in December 2005.
USNS Silas Bent (T-AGS-26) was a Silas Bent class survey ship acquired by the United States Navy in 1964 and delivered to the Military Sealift Command in 1965. Silas Bent spent her career in the Pacific Ocean performing oceanographic surveys. The ship was equipped with the Oceanographic Data Acquisition System (ODAS) as were the later oceanographic survey ships USNS Kane (T-AGS-27) and USNS Wilkes (T-AGS-33).
USS Allegheny (ATA-179) was an American Sotoyomo-class auxiliary fleet tug launched in 1944 and serving until 1968. She underwent conversion to a research vessel in 1952.
Project Magnet was a major geomagnetic survey effort from 1951 through 1994. The project originated in the U.S. Navy Hydrographic Office, renamed the U.S. Naval Oceanographic Office (NAVOCEANO), supporting world magnetic modeling and charting. The project used aircraft flying magnetic surveys worldwide. Additional magnetic data were collected with geophysical survey ships in conjunction with other projects for combination into final products. Data was used to support navigation of ships and aircraft and to meet Naval requirements as well as scientific research.
