USNS Neptune (ARC-2), was the lead ship in her class of cable repair ships in U.S. Naval service. The ship was built by Pusey & Jones Corp. of Wilmington, Delaware, Hull Number 1108, as the USACS William H. G. Bullard named for Rear Adm. William H. G. Bullard. She was the first of two Maritime Commission type S3-S2-BP1 ships built for the US Army Signal Corps near the end of World War II. The other ship was the Albert J. Myer, which later joined her sister ship in naval service as the USNS Albert J. Myer (T-ARC-6). [1] [2]
The ship was assigned to and largely worked on installation of the Sound Surveillance System (SOSUS) under its unclassified name for installation, Project Caesar.
Neptune's assignments were typically to transport, deploy, retrieve and repair submarine cables, tow cable plow [note 1] and acoustic projectors, and conduct acoustic, hydrographic, and bathymetric surveys. [3] Civilian cable engineers and specialist were involved during cable or surveying operations in addition to a Navy crew of nine officers and 142 enlisted personnel. [4] [note 2] In addition to cable operations and surveys for Project Caesar the ship supported experimental efforts and other projects. [5]
After completion for the US Army Signal Corps in February 1946, Neptune was handed to the Maritime Commission and placed in the James River reserve fleet on 2 March 1946. [6] [7] [8]
In 1952 Neptune was assigned to Project Caesar, the unclassified name for the installation phase of SOSUS. The system's mission was declassified in 1991. [9] On 17 February 1953 the ship was named Neptune and withdrawn from the reserve fleet. [6] The ship then went to the Bethlehem Steel Co. in Baltimore, Maryland for a number of modifications: e.g., electric cable machinery (in place of steam), precision navigation instrumentation, and a helicopter platform over the fantail. [5] Cable drums 15 ft (4.6 m) in diameter and bow sheaves spanning 12 ft (3.7 m) were among the more visible modifications. [10] On 1 June 1953 the ship was commissioned USS Neptune (ARC-2). [5]
The ship's operations were classified so few specific ones are public. One was the 1962 connection of the array once terminating at Naval Facility Cape May to Naval Facility Lewes necessitated by destruction of the Cape May shore station in the "Ash Wednesday" Storm. [9] [11] [12] [note 3]
From December 1965 through March 1966 Neptune was overhauled in Boston. [5] In 1973, Neptune transferred to the Military Sealift Command (MSC), was re-designated T-ARC-2, and continued operations with an MSC civil service crew.
Only two of the four cable ships available for Project Caesar had been designed and built as cable ships, the others being conversions and lacking some critical features needed for cable operations. The larger Aeolus and Thor were not suitable for modernization while Albert J. Myer and Neptune had cable ship features, including deeper draft than the larger ships, that made them suitable candidates for modernization. [13] In hearings for the 1980 appropriations the Navy requested an increase of $9.6 million over an original estimate of $14.5 million in Neptune conversion budget for a total of $24.1 million. The revised estimate was based on actual Myer conversion costs. In particular the Navy was questioned about conversion of merchant type hulls to cable ships and answered that conversion would be more expensive. Further, charter of commercial cable ships was done when needed, but expensive and those ships were not always available when required. The AT&T CS Long Lines was used on occasion to lay trunk cable at a daily cost of $30,000 vice Neptune's $19,200. Scheduled Project Caesar work required a minimum of three Navy cable ships. [14]
Neptune was extensively modernized in 1982 by General Dynamics Corporation in Quincy, Massachusetts. [note 4] That work included new turbo-electric engines. Neptune and sister ship Albert J. Myer, with Skinner Uniflow Reciprocating Steam Engines, were the last ships in the Navy to operate using reciprocating steam engines. [3]
Neptune performed cable repair duties all over the world until 1991, when she'd been in service for some 38 years. During her career, she received a Navy E ribbon in 1988.
Inactivated in 1991, the same year in which the SOSUS mission was declassified, she was placed in the James River reserve fleet near Ft. Eustis, VA on 24 September 1991. The ex-Neptune was removed from the fleet 6 December 1994 to stripped. [6] The ship was dismantled and recycled by International Shipbreaking Ltd. of Brownsville, TX in late 2005.
Sound Surveillance System (SOSUS) was the original name for 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 classified as well. 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. The name changed to Integrated Undersea Surveillance System (IUSS) in 1985, as the fixed bottom arrays were supplemented by the mobile Surveillance Towed Array Sensor System (SURTASS) and other new systems. 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.
Ramey Air Force Base also known as Borinquen Field, is a former United States Air Force base in Aguadilla, Puerto Rico. It was named after United States Army Air Forces Brigadier General Howard Knox Ramey. Following its closure, it was redeveloped into Rafael Hernandez Airport.
Naval Facility Bermuda, or NAVFAC Bermuda, was the operational shore terminus for one of the Atlantic Sound Surveillance System (SOSUS) array systems installed during the first phase of system installation and in commission from 1955 until 1992. The true surveillance mission was classified and covered by "oceanographic research" until the mission was declassified in 1991. The system's acoustic data was collected after the facility was decommissioned until the system was routed to the central processing facility, the Naval Ocean Processing Facility (NOPF), Dam Neck, Virginia in 1994.
USS Thor was a cable repair ship that supported Project Caesar, the unclassified name for installation of the Sound Surveillance System (SOSUS). Originally the Artemis-class attack cargo ship Vanadis (AKA-49) which was briefly in commission from 9 July 1945 to 27 March 1946, it was converted in 1955 after nine years in the reserve fleet.
USS Turandot (AKA-47) was an Artemis-class attack cargo ship named after the minor planet 530 Turandot, discovered by Max Wolf in 1904 and named by him after the title character in the Puccini opera of the same name.
Project Artemis was a United States Navy acoustics research and development experiment from the late 1950s into the mid 1960s to test a potential low-frequency active sonar system for ocean surveillance. The at sea testing began in 1960 after research and development in the late 1950s. The project's test requirement was to prove detection of a submerged submarine at 500 nmi. The experiment, covering a number of years, involved a large active element and a massive receiver array.
USNS Albert J. Myer (T-ARC-6) was the second of only two Maritime Commission type S3-S2-BP1 ships built for the US Army near the end of World War II intended to support Army Signal Corps communications cables. She is named for Brig. Gen. Albert J. Myer, the founder of the Signal Corps. The other ship was the William H. G. Bullard, later USS Neptune, which Myer later joined in naval service.
USS Aeolus (ARC-3) began service as USS Turandot (AKA-47), an Artemis-class attack cargo ship built by the Walsh-Kaiser Co., Inc. of Providence, Rhode Island. In 1954 she was converted into a cable repair ship to support Project Caesar, the unclassified name for installation of the Sound Surveillance System SOSUS. Aeolus was the first of two ships, the other being USS Thor (ARC-4), to be converted into cable ships. Aeolus performed cable duties for nearly thirty years, from 1955 to 1973 as a commissioned ship and from 1973 until 1985 as the civilian crewed USNS Aeolus (T-ARC-3) of the Military Sealift Command (MSC). The ship was retired in 1985 and sunk as an artificial reef in 1988.
Naval Facility Nantucket Island or simply Naval Facility Nantucket was a shore terminal of the Sound Surveillance System (SOSUS) active from 1955 to 1976. The true function of the system and the shore terminals, in which output of the array at sea was processed and displayed by means of the Low Frequency Analyzer and Recorder (LOFAR), was classified and the term "Naval Facility" was intentionally vague. Its function was described as oceanographic research.
USNS Flyer (T-AG-178), was a type C2-S-B1 cargo ship built for the Maritime Commission (MC) as Water Witch in service under charter by the commission to several lines until purchased in 1946 by United States Lines and renamed American Flyer. After being placed in the Reserve Fleet 14 December 1964 the title was transferred to the United States Navy for use as a deep ocean bathymetric survey ship supporting installation of the Sound Surveillance System (SOSUS). The Navy placed the ship in service 9 February 1965 with the name Flyer given on 22 March. The ship operated in that role until 1975.
SS Arthur M. Huddell is a Liberty ship built in the United States during World War II and is now a museum ship, SS Hellas Liberty, in Greece.
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.
USNS Zeus (T-ARC-7) is the first cable ship specifically built for the United States Navy. Though planned to be the first of two ships of her class, the second ship was not built, leaving Zeus as the only ship of her class. She is capable of laying 1,000 miles (1,600 km) of cable at depths of up to 9,000 feet (2,700 m).
Canadian Forces Station (CFS) Shelburne is a former Canadian Forces Station that was a shore terminus for the Sound Surveillance System (SOSUS) from 1955 to 1994. It was located in the Municipality of the District of Shelburne, Shelburne County, Nova Scotia.
Naval Facility Cape Hatteras was a Sound Surveillance System (SOSUS) shore terminal, one of the nine initial systems installed, located on Cape Hatteras near Buxton, North Carolina and adjacent to the old location of the Cape Hatteras lighthouse. NAVFAC Cape Hatteras, eighth of the initial nine Atlantic systems to be activated, was in commission 11 January 1956 to 30 June 1982.
Naval Facility Point Sur was one of 30 secret sites worldwide that were built during the Cold War to detect Soviet submarines. In 1958, the U.S. Navy built a Naval Facility ½ mile south of Point Sur on the Big Sur coast to provide submarine surveillance using the classified SOund SUrveillance System (SOSUS). The public was told the station was engaged in oceanographic research.
In 1958 Naval Facility (NAVFAC) Centerville Beach was the third Sound Surveillance System (SOSUS) shore terminal, in which output of the array at sea was processed and displayed by means of the Low Frequency Analyzer and Recorder (LOFAR), established on the Pacific coast. The previous year the last of the original Atlantic systems, Naval Facility Barbados, had become operational and the first of the Pacific systems had been installed at San Nicolas Island. Naval Facility Point Sur to the south had been commissioned on 8 January 1958. The SOSUS mission, as well as the name itself was classified until 1991. The facility was installed under the cover name Project Caesar and described as being engaged in "oceanographic research" with its actual role in undersea surveillance not revealed until two years before the facility closed.
Low Frequency Analyzer and Recorder and Low Frequency Analysis and Recording (LOFAR) are the equipment and process respectively for presenting a visual spectrum representation of low frequency sounds in a time–frequency analysis. The process was originally applied to fixed surveillance passive antisubmarine sonar systems and later to sonobuoy and other systems. Originally the analysis was electromechanical and the display was produced on electrostatic recording paper, a Lofargram, with stronger frequencies presented as lines against background noise. The analysis migrated to digital and both analysis and display were digital after a major system consolidation into centralized processing centers during the 1990s.
