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). [3]
Silas Bent (AGS-26), an oceanographic survey ship, was laid down in March 1964 by the American Shipbuilding Co. at Lorain, Ohio and launched on 16 May 1964 sponsored by sisters and granddaughters of Silas Bent, Miss Nancy M. McKinley and Mrs. Jeffrey R. Grandy. The ship was delivered to the Military Sea Transportation Service (now the Military Sealift Command) in July 1965. [1] [4]
Silas Bent—the first of a new class of oceanographic survey ships—was manned by a Civil Service crew and operated by the Military Sealift Command as an integrated system for the gathering of vital oceanographic data in both underway and on-station modes. The data she collected was recorded in a form immediately usable by computers. She was under the technical control of the Naval Oceanographic Office then located in Suitland, Maryland. The oceanographic survey ship completed her shakedown cruise during the winter of 1965 and 1966. The ship was assigned operations including the Navy's ASW/USW Oceanwide Survey Project supporting antisubmarine and undersea warfare weapons systems, primarily in the northern Pacific. [4] [5]
The ship completed the first full year of ASW/USW Oceanwide Survey Project, an effort to perform comprehensive surveys of strategic ocean areas, during fiscal year 1967. The first of the year was spent in the Atlantic with work in the Labrador Sea followed by a search for the reported American Scout Seamount. [6] The June 1966 survey found no evidence of a seamount with no soundings less than 2,362 fathoms (14,172 ft; 4,320 m) but did find strong returns from the Deep Scattering Layer that could be mistaken for shoals. [6] [7] Following additional surveys in the Gulf of Maine and north of Bermuda the ship was transferred to the Pacific in December 1966. The remainder of the fiscal year was spent surveying north of Hawaii into the Gulf of Alaska. [6]
On 8 August 1968 Silas Bent departed Hakodate, Japan for surveys east of Kamchatka but was diverted on 12 August to an area south of Amchitka Island, Alaska to assist in the search, termed CHASE VI SALVOPS, for the Liberty ship Robert L. Stevenson which was to be scuttled with a load of ammunition but failed to immediately sink and sunk in an unknown position. After six days on station the survey ship located the lost ship using a deep towed magnetometer and narrow beam echosounder with confirmation by photographs using a deep sea camera. [4] [5] After the search the ship returned to Japan for regular survey operations with a limited survey in the Sea of Okhotsk before transit to San Francisco arriving 30 October. On departure from San Francisco to Sasebo, Japan between 15 and 28 March 1968 the ship conducted underway transit data and planted current meter and thermister array buoys in the Sea of Japan. From 11 April to 14 May the ship conducted joint acoustic operations with the RV F. V. Hunt which was also assigned work for the ASW/USW Surveys Project. [5] [8] The two ships continued operations in the Sea of Japan and Sea of Okhotsk into June 1968. [5]
In 1972, she visited Japan, for the 2nd annual Ocean Development Conference held at Tokyo. During the conference, there were numerous tours and briefings held on Silas Bent describing, for the ocean scientists of the world, her capabilities for measuring bathymetric depth, magnetic intensity, gravity, surface temperature, seismic reflection, sound velocity, ambient light, and salinity. As of mid-September 1974, Silas Bent engaged in special operations in the area of Kodiak, Alaska. [4] The ship conducted surveys for about a month in the Sea of Okhotsk beginning on 25 September 1986. [9]
USNS Silas Bent was transferred under the Security Assistance Program to the Republic of Turkey 29 September 1999 and stricken from the Naval Vessel Register on 28 October 1999. [4]
As TCG Çeșme (A-599) the ship continued work as a hydrographic and oceanographic survey ship and was joined by sister ship USNS Elisha Kent Kane (T-AGS-27) which was renamed Çandarli (A-588). [10] [11]
Qualified Silas Bent personnel were eligible for the following:
Military Sealift Command (MSC) is an organization that controls the replenishment and military transport ships of the United States Navy. Military Sealift Command has the responsibility for providing sealift and ocean transportation for all US military services as well as for other government agencies. It first came into existence on 9 July 1949 when the Military Sea Transportation Service (MSTS) became solely responsible for the Department of Defense's ocean transport needs. The MSTS was renamed the Military Sealift Command in 1970.
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.
USNS Sumner (T-AGS-61) is a Pathfinder-class oceanographic survey ship that became operational in 1997. It is the fourth United States Navy ship named Sumner. These ships are crewed by a small crew of civilian mariners, supporting an even smaller contingent of United States Navy personnel.
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.
USNS Pathfinder is a United States Navy oceanographic survey ship, and the lead vessel of her class. Her mission is to collect acoustical, biological, physical, and geophysical surveys of the world's oceans. This data has many uses, but a primary focus is characterizing the ocean environment in order to improve the U.S. Navy's undersea warfare capabilities.
USNS Bowditch (T-AGS-21) was the lead ship of her class of oceanographic survey ships for the United States Navy. Launched as the SS South Bend Victory in 1945, Maritime Commission hull number MCV 694, a type VC2-S-AP3 Victory ship, she was named for Nathaniel Bowditch, the second U.S. Navy vessel named in his honor. The ship was acquired by the Navy in August 1957 and converted to an AGS at Charleston Naval Shipyard. Named Bowditch on 8 August 1957 and placed in service 8 October 1958 for operation by the Military Sea Transportation Service (MSTS).
NOAAS Thomas Jefferson is a National Oceanic and Atmospheric Administration (NOAA) hydrographic survey vessel in service since 2003. The ship was built for the United States Navy as USNS Littlehales (T-AGS-52) serving as one of two new coastal hydrographic survey vessels from 1992 until transfer to NOAA in 2003.
USNS Wyman (T-AGS-34) was an oceanographic survey vessel laid down on 18 July 1968 by the Defoe Shipbuilding Company of Bay City, Michigan. Launched on 30 October 1969, sponsored by Mrs. Francis J. Blouin, wife of the Deputy Chief of Naval Operations, Vice Admiral Francis J. Blouin; she was accepted by the Military Sealift Command (MSC) on 19 November 1971 at the Boston Naval Shipyard.
USNS Sgt. George D. Keathley, was a World War II United States cargo vessel that was used for troop transport and later converted to a survey vessel. She was laid down and launched as MS Alexander R. Nininger, Jr., then renamed MS Acorn Knot. She was put into US Army service as USAT Acorn Knot, then renamed USAT Sgt. George D. Keathley. She was transferred to the US Navy and became USNS Sgt. George D. Keathley (T-APC-117), but was later re-designated T-AGS-35. She was leased to the Republic of China, where she served as Chu Hwa (AGS-564). Both Nininger and Keathley were posthumous Medal of Honor recipients.
USS San Carlos (AVP-51) was a Barnegat-class seaplane tender built for the United States Navy during World War II. San Carlos, named after San Carlos Bay, Florida, was in commissioned from 1944 to 1947 and earned three battle stars for service in the Pacific during World War II. After eleven years in reserve, San Carlos was converted to oceanographic research ship USNS Josiah Willard Gibbs (T-AGOR-1)—named after American scientist Josiah Willard Gibbs—and placed in service as a non-commissioned ship of the Military Sea Transportation Service from 1958 to 1971. In December 1971, the ship was transferred to the Hellenic Navy as Hephaistos (A413), a motor torpedo boat tender. Hephaistos was struck from the rolls of the Hellenic Navy in April 1976.
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.
USNS Bartlett (T-AGOR-13) was a Robert D. Conrad-class oceanographic research ship acquired by the U.S. Navy (USN) in 1969. She was named after oceanographer Captain John R. Bartlett of the USN. 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.
Silas Bent III (1820–1887) was a naval officer in the U.S. Navy prior to the American Civil War. Silas Bent sailed both the Atlantic and Pacific Oceans and was recognized by the Navy for his contributions to oceanography which were published by the Navy. At the outset of the American Civil War, Silas Bent resigned his commission, as his sympathy was for the Southern cause.
USNS S. P. Lee was laid down on 27 June 1966 by the Defoe Shipbuilding Co., Bay City, Michigan as yard hull number 441. The ship, sponsored by Mrs. David Scull, great granddaughter of Admiral Lee, was launched on 19 October 1967 and delivered to the navy on 2 December 1968.
The Silas Bent class is frequently found applied to four ships though the Naval Vessel Register and some sources officially break them into the subclasses of AGS-26 and AGS-33. Silas Bent was the first of the first four purpose built ships for U.S. Navy surveys. Previous ships had been modifications of various naval types.
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.
USNS John McDonnell (T-AGS-51) was a hydrographic survey ship operated by the Military Sealift Command (MSC) with a contract crew for the Naval Oceanographic Office which assigned a military and civilian hydrographic detachment to conduct coastal surveys. The ship and its sister, USNS Littlehales (T-AGS-52), were replacements for the coastal hydrographic survey vessels USNS Chauvenet (T-AGS-29) and USNS Harkness (T-AGS-32).
USNS Kane (T-AGS-27) was a Silas Bent-class survey ship acquired by the United States Navy and delivered to Military Sealift Command in 1967. Kane spent her career performing oceanographic surveys. The ship was equipped with the Oceanographic Data Acquisition System (ODAS) as were oceanographic survey ships USNS Silas Bent (T-AGS-26) and USNS Wilkes (T-AGS-33).
USS John Blish was a Patrol Craft Sweeper (PCS) of the PCS-1376-Class, five of which were converted to small hydrographic survey vessels designated AGS and later coastal survey vessels, AGSc, that conducted hydrographic surveys for the United States Navy during and immediately after the Second World War. The small PCS type vessels assigned to the United States Navy Hydrographic Office missions conducted pre invasion surveys, sometimes under fire, with the survey crews erecting signals for survey and later navigation, laying buoys and placing lights.
USNS Chauvenet (T-AGS-29) was a coastal survey ship laid down on 24 May 1967, at Upper Clyde Shipbuilding Corp., Glasgow, Scotland. The ship was the second survey ship, Chauvenet (AGS-11) being the first, named for William Chauvenet (1820-1870). He was instrumental in the founding of the United States Naval Academy at Annapolis, MD. The mathematics department of the US Naval Academy in Annapolis was founded by Chauvenet and is housed in Chauvenet Hall. Chauvenet was launched on 13 May 1968, delivered to the US Navy, 13 November 1970 and placed in service with the Military Sealift Command (MSC) as USNS Chauvenet (T-AGS-29). The ship conducted coastal hydrographic and topographic surveys under the technical direction of the Oceanographer of the Navy through the U.S. Naval Oceanographic Office (NAVOCEANO). The ship was assigned to the Pacific for surveys, sister ship Harkness (T-AGS-32) was assigned Atlantic duties, doing so until inactivated in November 1992.
