Signals intelligence (SIGINT) is intelligence-gathering by interception of signals, whether communications between people or from electronic signals not directly used in communication. Signals intelligence is a subset of intelligence collection management. As classified and sensitive information is usually encrypted, signals intelligence in turn involves the use of cryptanalysis to decipher the messages. Traffic analysis—the study of who is signaling whom and in what quantity—is also used to integrate information again.
The Defence Research Establishments were a number of separate UK Ministry of Defence Research Establishments, dating back to World War II, World War I, or even earlier. Each establishment had its own head; known as the Director or the Superintendent. Prior to the formation of the Ministry of Defence each of the three Services, i.e. the Royal Air Force, the Admiralty and the War Office, had their own research establishments; although some establishments had tri-service functions.
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers.
The Admiralty Mining Establishment originally known as the Mine Design Department was a technical department of the British Royal Navy responsible for both the design of naval mines and the development of suitable countermeasures from 1915 to 1951
Naval Surface Warfare Center Crane Division is the principal tenant command located at Naval Support Activity Crane. NSA Crane is a United States Navy installation located approximately 35 miles (56 km) southwest of Bloomington, Indiana, and predominantly located in Martin County, but small parts also extend into Greene and Lawrence counties. It was originally established in 1941 under the Bureau of Ordnance as the Naval Ammunition Depot for the production, testing, and storage of ordnance under the first supplemental Defense Appropriation Act. The base is named after William M. Crane. The base is the third largest naval installation in the world by geographic area and employs approximately 3,300 people. The closest community is the small town of Crane, which lies adjacent to the northwest corner of the facility.
Ralph Benjamin was a British scientist and electrical engineer.

The Operational Test and Evaluation Force (OPTEVFOR) serves as an independent and objective agency within the United States Navy for the operational testing and evaluation (OT&E) of naval aviation, surface warfare, submarine warfare, C4I, cryptologic, and space systems in support Navy and U.S. Department of Defense acquisition programs.
The TF-2000-class destroyer is a projected anti-air warfare guided-missile destroyer currently undergoing development by the Turkish Naval Institute. The class will provide survivability in the presence of aerial threat and also support mission functions such as command, control, and communications, reconnaissance, early warning, surface warfare, anti-submarine warfare and electronic warfare. Moreover, once in service, the TF-2000s are slated to be an integral part of Türkiye's expeditionary strike groups centered around the TCG Anadolu LHD and the country's future aircraft carrier(s). The TCG Anadolu is to be followed up by the TCG Trakya light aircraft carrier and President Erdoğan has also hinted at the construction of a larger aircraft carrier that is to be designed in cooperation with Spain. These capital vessels require destroyer escorts to defend them against enemy aircraft, ships and submarines; in other words, the perfect role for the TF-2000s once these new designs are slated for operational service by 2038. On 5 December 2007, Defence Industry Executive Committee approved plans to build six ships of this class. In January 2013, it was announced that Turkey was planning to acquire a total of 8 TF-2000 destroyers, which was confirmed at the International Defence Industry Fair (IDEF) 2021. With the realization of the project, it is intended to improve the anti-air warfare (AAW) capabilities of the Turkish Navy.
The Admiralty Research Establishment was formed on 1 April 1984 from various Admiralty establishments. It became part of the Defence Research Agency on 1 April 1991.
The Admiralty Underwater Weapons Establishment was an Admiralty research department dedicated to underwater detection systems and weapons. It was formed at the Isle of Portland in 1959 and later became part of the Admiralty Research Agency (ARE) in 1984.
The Secret War was a six-part television series that was produced by the BBC in conjunction with the Imperial War Museum (IWM) that documented secret technical developments during the Second World War. It first aired during 1977 and was presented by William Woollard, drawing on the first-hand recollections of participants from both sides. The principal interviewee was R. V. Jones, whose autobiography informed much of the research before its publication. The opening music was an excerpt from Mussorgsky's Pictures at an Exhibition. The closing music was by the BBC Radiophonic Workshop.
The Admiralty Compass Observatory was a department of the British Royal Navy. It was established in 1842 to provide the Royal Navy with services for the design, development, inspection, testing and repair of compasses and certain other instruments. It subsequently undertook requirements for the other services as appropriate. Lord Kelvin is said to have called it 'the Temple of Accuracy'.
The Admiralty Naval Staff was the former senior command, operational planning, policy and strategy department within the British Admiralty. It was established in 1917 and existed until 1964 when the department of the Admiralty was abolished. It was replaced by the Ministry of Defence as part of the Ministry of Defence Navy Department.
The Admiralty Signal and Radar Establishment (ASRE) originally known as the Experimental Department and later known as the Admiralty Signal Establishment (ASE) was a research organisation of the British Royal Navy established in 1917. It existed until 1959 when it was merged with the Admiralty Gunnery Establishment to form the Admiralty Surface Weapons Establishment (ASWE). Its headquarters were located in Haslemere, Surrey, England.
The Gunnery Division was a Directorate of the Admiralty Naval Staff of the Royal Navy responsible for the tactical use of naval weapons and the training of naval personnel in relation to operational requirements. It was established in 1920 when the Gunnery and Torpedo Division was separated into an independent Gunnery Division and Torpedo Division. It existed until 1964 when the Department of Admiralty was abolished and replaced by a new Ministry of Defence.
The Admiralty Gunnery Establishment (AGE), originally known as Fire Control Group (ARL) and later known as the Admiralty Surface Weapons Establishment (ASWE), was an admiralty research department primarily responsible for Army and Navy gunfire control work between 1931 and 1959.
Elizabeth "Betty" Audrey Killick was a British naval electronics engineer who worked on radar and weapons systems for the Ministry of Defence. In 1982, she became the first woman to be elected a Fellow of the Royal Academy of Engineering.
The Vulnerability Assessment Laboratory (VAL) was a research institution under the U.S. Army Materiel Command (AMC) that specialized in missile electronic warfare, vulnerability, and surveillance. It was responsible for assessing the vulnerability of Army weapons and electronic communication systems to hostile electronic warfare and coordinating missile electronic countermeasure efforts for the U.S. Army. VAL was one of the seven Army laboratories that merged to form the U.S. Army Research Laboratory (ARL) in 1992.
