1164-625: A nation in Civil War as the Lazzaroni had hoped, nor did it centralize American scientific efforts. However, election to the National Academy did come to be considered "the pinnacle of scientific achievement for Americans" until the establishment of the Nobel Prize at the end of the 19th century. In 1870, the congressional charter was amended to remove the limitation on the number of members. In 2013, astrophysicist Neil deGrasse Tyson

1261-588: A new type of fixed bottom system, terminus was made at NAVFAC Brawdy, Wales. Stalwart makes first SURTASS operational patrol and system name is changed from SOSUS to Integrated Undersea Surveillance System (IUSS).

The museum's exhibits focused on climate change and infectious disease . In 2017,

2328-588: The "Ash Wednesday" Storm . NAVFAC Argentia got a 2X20 element array in 1963. A 1965 decision to deploy systems to the Norwegian Sea was followed in 1966 with a system terminating at Keflavik, Iceland with the first 3X16 array system while Western Electric installed data links by land line to OCEANSYSLANT and OCEANSYSPAC. New systems were installed during 1968 at Midway Island and Guam . COMOCEANSYSPAC relocated to Ford Island, Hawaii from Treasure Island, California . The shallow water system at Argentia

2425-562: The Ivy League , account for nearly 28% of all members ever elected. Those ten are also precisely the only institutions in the entire history of the NAS to have had 100 or more members overall. On the list for living members, only 14 institutions have 50 or more members overall, including the medical school (where it applies). They represent 32% of all living members of the NAS. The National Academy of Sciences maintains multiple buildings around

2522-511: The Atlantic and were getting dangerously close. That approach raised the threat level to several SAC bases along the coast. Rather than prosecute the contacts and reveal how closely the system could track the submarines, the SAC bases put more bombers on ready alert assuming the Soviets would notice. The submarines did not withdraw so SAC dispersed the bombers to bases as far away as Texas. Though there

2619-631: The Chief of Naval Operations. With the new, mobile systems Towed Array Sensor System (TASS) and the Surveillance Towed Array Sensor System (SURTASS) entering the system, the SOSUS name was changed in 1984 to Integrated Undersea Surveillance System (IUSS) to reflect the change from bottom fixed systems alone. In 1990 officers were authorized to wear IUSS insignia. Finally, with "undersea surveillance" so openly displayed,

More original NAVFACs closed during 1993 with NAVFACs Centerville Beach, California and Adak, Alaska closing with their acoustic data routed to NAVFAC Whidbey Island. The facility at Whidbey, with multiple systems terminating there became Naval Ocean Processing Facility (NOPF) Whidbey. During 1994 Canadian Forces Shelburne, Nova Scotia closes as does NAVFAC Argentia with HMCS Trinity established at Halifax Nova Scotia with operation as Canadian Forces IUSS Centre (CFIC). NAVFAC Bermuda data

3201-422: The Navy. Some did so and remained in the system as civil service or contractor personnel. The first women were assigned to NAVFAC Eleuthera when an officer and ten enlisted women were assigned in 1972. Due to the fact that the SOSUS community departed from the usual Navy cultural routine, with repeat assignments within the small community, women were able to serve in a warfare specialty without shipboard duty that

3298-651: The RAINFORM was abandoned and replaced. For much of the system's operation, direct action based on SOSUS contacts was avoided. An example was subject to a box piece in the January 5, 1981 issue of Newsweek titled "A Soviet War of Nerves" concerning an incident from August 1978. An alert to Atlantic Fleet, Strategic Air Command (SAC) and the Pentagon came from "underwater listening devices at several secret Navy installations" that two Yankee class nuclear-armed submarines had left their usual patrol areas 1,200 miles out in

3395-675: The Sea describes the production arrays as being 1,800 ft (548.6 m) long. In 1954, the order was increased by three more Atlantic stations and an extension into the Pacific, with six stations on the West Coast and one in Hawaii. In September 1954, Naval Facility Ramey was commissioned in Puerto Rico. Others of the first Atlantic phase followed, and in 1957 the original operational array at Eleuthera got an operational shore facility as

3492-460: The Sea , contains a segment at about 9:22 minutes into the film concerning the search for a suitable array location and laying the array. It describes the operational arrays as being 1,800 ft (548.6 m) long. In 1954 ten additional arrays were ordered with three more in the Atlantic, six on the Pacific coast and one in Hawaii. The cable ships Neptune and Albert J. Myer were acquired to support Project Caesar with later addition of

3589-659: The Senate Committee on Armed Services the request for funding of recreational and other support buildings for the Naval Facility Cape Hatteras the Navy noted it was part of a program supporting continental air and missile defense forces without mention of its role in tracking Soviet missile submarines. In 1954 the Fleet Sonar School at Key West established a Sound Search Course for training personnel. The highly classified program

3686-515: The Senate and House approved it, and President Lincoln signed it. Although hailed as a great step forward in government recognition of the role of science in American society, at the time, the National Academy of Sciences created enormous ill-feelings among scientists, whether or not they were named as incorporators. The act states: [T]he Academy shall, whenever called upon by any department of

3783-677: The Sound Surveillance System with the acronym SOSUS. Both the full name and acronym were classified. There were occasional slips. A contractor for the Office of Naval Research, Fleet Analysis and Support Division published an unclassified report with "SOSUS" in association with the system acronym "SOSS", defined as "Sound Search Station," and a capability to display data from sonobuoys side by side on either aircraft or SOSS displays in contact classification as either friendly or unfriendly targets. The unclassified name Project Caesar

3880-807: The Soviet submarine threat consisting primarily of a large fleet of diesel submarines. That group also recommended a system to monitor low-frequency sound in the SOFAR channel using multiple listening sites equipped with hydrophones and a processing facility that could calculate submarine positions over hundreds of miles. As a result of the Hartwell group's recommendations, the Office of Naval Research (ONR) contracted with American Telephone and Telegraph Company (AT&T), with its Bell Laboratories research and Western Electric manufacturing elements, to develop

4074-430: The U.K. has data remoted directly to NOPF Dam Neck and is decommissioned. British and US Forces then begin joint, combined operations at NOPF Dam Neck. Project Caesar, from initial bathymetric and acoustical surveys through cable installation and turnover to operations, was managed by Bureau of Ships (BuShips) from 1951 until 1964. All the direct support through contracts with Western Electric, Bell Labs and ship schedules

4171-883: The US Navy approached the Committee for Undersea Warfare, an academic advisory group formed in 1946 under the National Academy of Sciences , to research antisubmarine warfare. As a result, the Navy formed a study group designated Project Hartwell , named for the University of Pennsylvania's G.P. Hartwell who was the Deputy Chairman of the Committee for Undersea Warfare, under Massachusetts Institute of Technology (MIT) leadership. The Hartwell panel recommended spending of US$ 10,000,000 (equivalent to $ 128,060,000 in 2023) annually to develop systems to counter

The building has a neoclassical architectural style and was built by architect Bertram Grosvenor Goodhue . The building

4365-467: The ability ad-hoc to delegate certain tasks to committees. For example, the Committee on Animal Nutrition has produced a series of Nutrient requirements of domestic animals reports since at least 1944, each one being initiated by a different sub-committee of experts in the field for example on dairy cattle . The National Academy of Sciences meets annually in Washington, D.C., which is documented in

4462-518: The acoustic environment drove much of the oceanographic research by both the Navy and institutions with Navy funding for oceanography. A major, long-term research program spanning over 25 years, the Long Range Acoustic Propagation Program (LRAPP), made significant progress in such understanding and influenced decisions in SOSUS, significantly the SOSUS expansion into the eastern Atlantic. The hardware technology

4559-493: The addition of women to the academy "continues at a dismal trickle"; at that time there were 1,516 male members and 57 female members. The National Academy of Sciences is one of the 135 member organizations of the International Science Council (ISC). Although there is no formal relationship with state and local academies of science, there often is informal dialogue. The National Academy is governed by

The Keck Center provides meeting space and houses the National Academies Press Bookstore. The Marian Koshland Science Museum of

4753-458: The cable ships Aeolus and Thor . Other ships were added for acoustic and bathymetric surveys and cable support. SOSUS systems consisted of bottom-mounted hydrophone arrays connected by underwater cables to facilities ashore. The individual arrays were installed primarily on continental slopes and seamounts at the axis of the deep sound channel and normal to the direction in which they were to cover. The combination of location within

4850-428: The commercial telephone cable technology for the application requiring a shore facility within about 150 nmi (170 mi; 280 km) from the array and thus within that distance from the continental shelf locations suitable for the array. The cable of the time consisted of multi-pair wire connected to the forty hydrophones of the array. New coaxial multiplexed commercial telephone system cable, designated SB, using

4947-654: The consolidation of the Aleutian station at Adak in 1993, the North Atlantic's Argentia in 1995, and those termed "Special Projects" in 1997 and 1998. The western Atlantic system consolidation was centered on the establishment of the Naval Ocean Processing Facility (NOPF) at Dam Neck, Virginia beginning with closure of NAVFACs Eleuthera and Grand Turk. During 1981 Naval Ocean Processing Facility (NOPF), Ford Island became operational and

5044-437: The decommissioning of NAVFAC Midway with that system's data routed to NAVFAC Barbers Point was completed. NAVFAC Lewes, Delaware closed that year. NAVFAC Cape Hatteras closed in 1982 and in 1983 Midway acoustic data was rerouted directly to Naval Ocean Processing Facility, Ford Island. In 1984 the first SURTASS vessel, USNS  Stalwart  (T-AGOS-1) arrives at Little Creek, Virginia . USNS  Zeus  (T-ARC-7) ,

5141-601: The eastern Atlantic. NAVFAC Brawdy became the first "super NAVFAC" with some four hundred U.S. and U.K. military and civilian personnel assigned. The facility ( 51°52′15.3″N 005°08′13.8″W  /  51.870917°N 5.137167°W  / 51.870917; -5.137167 ) was adjacent to the Royal Air Force Station Brawdy which had returned to RAF control during February 1974 after closure in 1971. In 1975 Mizar left Naval Research Laboratory service and joined Project Caesar. In April 1974

5238-469: The entire history of the NAS, Harvard University is associated with the most members (331) overall, while the University of California at Berkeley is associated with the most members (255) without including the medical school. E.g. of the topmost schools, UC Berkeley/MIT/Princeton/Caltech do not have medical schools, while Harvard/Stanford do. The top ten institutions, two of which are from the University of California System and another four of which are in

5335-401: The facility had access to the operational part of the installations. The early arrangement can be seen in the vertical photograph of Naval Facility Nantucket and later in the photograph of Naval Facility Brawdy below. Equipment in the terminal buildings was installed by specially cleared Western Electric Company personnel. Western Electric and ONR representatives met on 29 October 1950 to draft

5432-553: The form's fields and codes. As a result, people in the fleet often did not know of the system's dedicated antisubmarine mission. Even when they knew they often did not know of its actual performance or exact role. This later had implications as the Cold War ended and budgets became an issue. In the late 1980s and early 1990s, the system was opened to tactical use and the fleet began to see the contact information in other formats readily understandable by fleet antisubmarine forces. In 1997

5529-399: The government 'whenever called upon' by any government department", an objective that promulgated the academy with the broad and enduring purpose of enriching and providing resources to any part of the federal government—rather than as a tool of one branch, or executive agencies, which adds a risk or propensity of becoming the tool of one part of the government. The goal was somewhat unusual at

5626-439: The last of the first phase of Atlantic systems. The same year, the Pacific systems began to be installed and activated. Over the next three decades, more systems were added; NAVFAC Keflavik , Iceland in 1966 and NAVFAC Guam in 1968 being examples of expansion beyond the western Atlantic and eastern Pacific. Shore upgrades and new cable technology allowed system consolidation until by 1980 that process had resulted in many closures of

6014-469: The museum closed and made way for a new science outreach program called LabX. The Act of Incorporation, signed by President Abraham Lincoln on March 3, 1863, created the National Academy of Sciences and named 50 charter members. Many of the original NAS members came from the so-called " Scientific Lazzaroni ", an informal network of mostly physical scientists working in the vicinity of Cambridge, Massachusetts ( c.  1850 ). In 1863,

6111-648: The ocean . From 2–19 January 1952 the British cable layer Alert installed the first full sized, 1,000 ft (304.8 m) long, forty transducer element operational array in 240 fathoms (1,440.0 ft; 438.9 m) off Eleuthera in the Bahamas. Successful tests with a target submarine resulted in the order to install a total of nine arrays along the coast of the Western North Atlantic. The 1960 secret, limited distribution Navy film Watch in

6208-581: The ocean and the sensitivity of arrays allowed the system to detect acoustic power of less than a single watt at ranges of several hundred kilometres. SOSUS shore terminal processing stations were designated with the vague, generic name of Naval Facility (NAVFAC). By the 1980s improved communications technology allowed the array data once processed in individual Naval Facilities to be sent to central processing centers (Naval Ocean Processing Facility (NOPF)) for centralized processing of multiple fixed and mobile array information. The first systems were limited by

6305-433: The one new cable ship of the requested two, enters the "Caesar fleet" for operations. Atlantic NAVFAC Antigua and Pacific NAVFACs at San Nicolas Island and Point Sur in California closed. Point Sur acoustic data was routed to NAVFAC Centerville. Consolidation and new systems brought further change in 1985. NAVFAC Barbers Point closes with acoustic data directed to NOPF, Ford Island. The Fixed Distributed System (FDS) test array,

6402-456: The organizers enlisted the support of Alexander Dallas Bache , and also Charles Henry Davis , a professional astronomer who had been recently recalled from the Navy to Washington to head the Bureau of Navigation . They also elicited support from Swiss-American geologist Louis Agassiz and American mathematician Peirce , who together planned the steps whereby the National Academy of Sciences

6499-519: The problem. The forty hydrophones spaced on the array provided the aperture for signal processing to form horizontal azimuthal beams of two to five degrees wide, each beam with a LOFAR analyzer and capability to do narrow-band frequency analysis to discriminate signal from ocean noise and to identify specific frequencies associated with rotating machinery. The NAVFAC watch floor had banks of displays using electrostatic paper, similar to that used for echograms in depth finders. The product of these displays

The Ocean System commands, COMOCEANSYSLANT (COSL) and COMOCEANSYSPAC (COSP), then began to reflect their true nature as Undersea Surveillance commands COMUNDERSEASURVLANT (CUSL) and COMUNDERSEASURVPAC (CUSP) under the Integrated Undersea Surveillance System (IUSS) name that had come into effect in 1985 as systems other than fixed emerged. SOSUS

6693-488: The second President of NAS. Agassiz, Davis, Peirce, Benjamin Gould and Senator Wilson met at Bache's house and "hurriedly wrote the bill incorporating the Academy, including in it the name of fifty incorporators". During the last hours of the session, when the Senate was immersed in the rush of last-minute business before its adjournment, Senator Wilson introduced the bill. Without examining it or debating its provisions, both

6790-432: The ship was reported as already being funded by Naval Electronics Systems Command (NAVELEX), where the project program management resided, and no longer funded as an oceanographic ship. By 1979 it was the most recently built ship of the five project ships that then included cable repair ships Albert J. Myer and Neptune due for modernization and the larger repair ship Aeolus that was uneconomical to repair and marginal as

6887-491: The sound channel enabled beamforming processing at the shore facilities to form azimuthal beams. When two or more arrays held a contact, triangulation provided approximate positions for air or surface assets to localize. SOSUS grew out of tasking in 1949 to scientists and engineers to study the problem of antisubmarine warfare . It was implemented as a chain of underwater hydrophone arrays linked by cable, based on commercial telephone technology, to shore stations located around

6984-506: The systems were accepted and turned over for operation, came under Commander, Oceanographic System Atlantic (COMOCEANSYSLANT) in 1954. Commander, Oceanographic System Pacific (COMOCEANSYSPAC) was established for the Pacific systems in 1964. Within the Office of Chief of Naval Operations the Director ASW Programs OP-95 was established in 1964. In 1970 COMOCEANSYSLANT and COMOCEANSYSPAC were designated as major commands by

7081-468: The target. The first Atlantic stations, ranging from Nova Scotia to Barbados, formed a long line semicircle looking into the Western Atlantic basin with geographic separation for contact correlation and triangulation. The combination of research and engineering under Jezebel and Michael into an actual broad area surveillance system as seen by Project Hartwell's Frederick V. Hunt became

7178-485: The time, and also different than other knowledge based entities serving a branch of government, such as the Library of Congress. The academy receives no compensation from the government for its services. As of 2024 , the National Academy of Sciences includes 2,687 NAS members and 531 international members . It employed about 1,100 staff in 2005. Some 190 members have won a Nobel Prize. By its own admission in 1989,

7275-489: The two Midway arrays could eventually be remoted directly to NOPF Ford Island. This first generation WADR was used to consolidate array data from the California facilities at San Nicolas Island and Point Sur in 1984. Those were followed by remoting Hawaii's Barber's Point in 1985, the Pacific Northwest arrays at Pacific Beach and Coos Head in 1987, and Bermuda in the Atlantic in 1992. A second generation WADR allowed

7372-421: The western Atlantic Ocean from Nova Scotia to Barbados . The first experimental array was a six-element test array laid at Eleuthera in the Bahamas in 1951, followed, after successful experiments with a target submarine, in 1952 by a fully-functional 1,000 ft (304.8 m), forty-hydrophone array. At that time the order for stations was increased from six to nine. The then-secret 1960 Navy film Watch in

7469-614: The wreckage of the American nuclear attack submarine USS  Scorpion , lost near the Azores in May. National Academy of Sciences The National Academy of Sciences ( NAS ) is a United States nonprofit, non-governmental organization . NAS is part of the National Academies of Sciences, Engineering, and Medicine , along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM). As

7566-534: Was a shallow water, curved array with ten eight-element arrays installed on two cables with each cable having the capacity for the usual forty elements. In 1962 a new system was installed terminating at Naval Facility Adak in the Aleutians . The system terminating at Cape May was rerouted to a new Naval Facility Lewes , Delaware, with upgraded processing, after the NAVFAC Cape May had been destroyed in

7663-783: Was asked to write a speech for the 150th anniversary of the Gettysburg Address in which he made the point that one of Lincoln's greatest legacies was establishing the National Academy of Sciences in that same year, which had the long-term effect of "setting our Nation on a course of scientifically enlightened governance, without which we all may perish from this Earth". The academy currently (as of late-2024) has 6892 members, including international ones, both past and present. 3218 of them are living. Existing members elect new members for life. Up to 120 members are elected every year while up to 30 foreign citizens may be elected as international members annually. The election process begins with

7760-946: Was behind the "Green Door" which became a name for the program itself as well as being seen as a term for the secrecy. In 1954 three full systems to include a NAVFAC terminus were installed with arrays terminating at NAVFACs at Ramey Air Force Base, Puerto Rico in September, Grand Turk in October, and San Salvador in December. Systems terminating at Naval Facility Bermuda , Canadian Forces Station (CFS) Shelburne, Nova Scotia , Nantucket , and Cape May were installed during 1955. Systems terminating at Naval Facility Cape Hatteras and Naval Facility Antigua and two Evaluation Centers, forerunners of NOPFs, were established in New York and Norfolk during 1956. The initial array at Eleuthera got

7857-522: Was capable of oceanic surveillance with the long ranges made possible by exploiting the deep sound channel , or SOFAR channel. An indication of ranges is the first detection, recognition and reporting of a Soviet nuclear submarine coming into the Atlantic through the Greenland-Iceland-United Kingdom (GIUK) gap by an array terminating at NAVFAC Barbados on 6 July 1962. The linear arrays with hydrophones placed on slopes within

7954-523: Was closely held on a strict need-to-know basis that was close to Sensitive Compartmented Information even though it was classified at the Secret level. Even the Fleet had little knowledge of the system or its function. Contact data reaching the fleet was in a strictly formatted message designated RAINFORM, hiding the source, that the fleet often did not understand without reference to publications to understand

8051-493: Was deactivated. In 1965 Flyer was acquired as a bathymetric survey ship. The satellite communications ship Kingsport joined the project in 1967 for acoustic and bathymetric work. The first NAVFAC decommissioning took place with the isolated duty station at NAVFAC San Salvador, Bahamas shut down on 31 January 1970. The old station is now home of the Gerace Research Center . NAVFAC Barbers Point

8148-469: Was dedicated in 1924 and is listed on the National Register of Historic Places . Goodhue engaged a team of artists and architectural sculptors including Albert Herter , Lee Lawrie , and Hildreth Meière to design interior embellishments celebrating the history and significance of science. The building is used for lectures, symposia, exhibitions, and concerts, in addition to annual meetings of

8245-435: Was given the name Project Jezebel . The origin of the project name was explained by Robert Frosch to Senator Stennis during a 1968 hearing. It was because of the low frequencies, "about the A below middle C on the piano" (about 100–150 cycles) and "Jezebel" being chosen because "she was of low character." This refers to A2 on the musical scale, which is technically two A's below middle C. Jezebel and LOFAR branched into

8342-473: Was given to cover development and installation of the resulting system. A cover story was developed to explain the visible shore installations, the Naval Facilities, and the commands under which they fell. The cover explained that data gathered by oceanographic and acoustic surveys with ships could at times be collected "more expeditiously and more economically by means of shore stations. These are

8439-541: Was introduced with fiber optic cable. Cable technology and signal processing improved and upgrades were made to the original installations. Cable technology made it possible to site arrays further from shore into the ocean basins. New signal processing capabilities allowed for innovations such as the split array in which a single line array was divided into segments, each separately processed, then electronically recombined to form narrower beams for better bearing and cross fixes between arrays. Augmenting these local improvements

8536-447: Was largely that of the commercial telephone system and oil exploration. Cable laying was a capability AT&T and other entities had developed for decades for commercial communications cables . The understanding of the ocean acoustic environment made the system possible rather than development of new technology. SOSUS was a case of new understanding of the environment and then application of largely existing technology and even equipment to

8633-423: Was on installation of MILS in the Atlantic and Pacific test ranges. Arrays of hydrophones placed around the target area located the missile warhead by means of measuring arrival times of the explosion at the various hydrophones of a SOFAR charge in the test warhead. During that period an atypical SOSUS system was installed in 1959 at Argentia, Newfoundland to provide surveillance for approaches to Hudson Bay . It

8730-446: Was placed under Commander, Submarine Force, U.S. Atlantic Fleet. The LOFARgram representation of acoustics in black, gray and white with an operator trained and adapted to interpreting that display was the critical link in the system. Experienced operators that could detect subtle differences and with practice could detect faint signatures of targets were vital to detection. It was even found that color blindness could be an advantage. It

8827-467: Was soon apparent that the Navy's practice of short term tours and transfer out of the system was a problem. Commander Ocean Systems Atlantic launched an effort in 1964 to create a rating peculiar to SOSUS and allow personnel to remain within the community. It took five years for Bureau of Personnel to create the rating of Ocean Technician [OT]. That bureau did not do the same for officers thus forcing those with experience to either leave for new duties or leave

8924-557: Was still being denied. That opened a new field for women outside the usual medical, education, or administrative specialties. SOSUS assignment qualified as important as sea duty on a Cold War front line. In 1961 the system proved its effectiveness when it tracked USS  George Washington on her first North Atlantic transit to the United Kingdom. The first detection of a Soviet nuclear submarine occurred on 6 July 1962 when NAVFAC Barbados recognized and reported contact #27103,

9021-514: Was the LOFARgram which graphically represented acoustic energy and frequency against time. Those were examined by the personnel trained to identify submarine signatures. When two or more arrays held a target the bearings from each array gave an estimated target position by triangulation. The system could provide cuing information on the presence of the submarines and an approximate location for air or surface antisubmarine warfare assets to localize

9118-577: Was the increased central processing in centers that eventually became the Naval Oceanographic Processing Facilities. There the contacts of multiple arrays were correlated with other intelligence sources in order to cue and provide the search area for air and surface antisubmarine assets to localize and prosecute. The system was considered a strategic, not tactical, system at the time and part of continental defense. In military construction hearings during 1964 before

9215-645: Was to be established. Senator Henry Wilson of Massachusetts was to name Agassiz to the Board of Regents of the Smithsonian Institution . Agassiz was to come to Washington, D.C., at the government's expense to plan the organization with the others. This bypassed Joseph Henry , who was reluctant to have a bill for such an academy presented to Congress . This was in the belief that such a resolution would be "opposed as something at variance with our democratic institutions". Nevertheless, Henry soon became

9312-664: Was to terminate in Canada but a change in government there precluded a facility in Canada at the time. The sixth array, requiring redesign of the cable and repeater system, was thus terminated at Naval Facility Pacific Beach, making it a dual array facility. From 1958 to 1960 Project Caesar assets began work installing the Missile Impact Location System (MILS), based on technology and installation methods similar to those for SOSUS, in support of Air Force ICBM tests. The survey and installation focus in that period

9409-446: Was under this management. In 1964 the project was placed under Industrial Manager, Potomac River Command and then Naval District Washington in 1965. In 1966 the project came under Naval Electronics Systems Command (NAVELEX PME-124) where it remained through the name change in 1986 to Space and Naval Warfare Systems Command (SPAWARSYSCOM PMW 180) and a move from Arlington to San Diego in 1997. The Navy operational side, taking over when
