Radar, Anti-Aircraft
Radar, Anti-Aircraft, or simply AA radar for short, was a classification system for British Army radars introduced in 1943 and used into the 1960s when these systems were replaced by missiles with their own integral radar systems. The classification included subcategories, Number 1 through 8, as well as the many individual systems which were assigned Marks. Some of the Army radars pre-date the introduction of this classification system and had their own nomenclature that tended to remain in use even after they officially received new names. Notable among these are the Gun Laying and Searchlight Control categories. Additionally, equipment introduced after the classification system often have rainbow codes that they are well known by. Some were also used by the Royal Air Force and thus also had an AMES number. Number 1 Originally known as GL Mk. I radar, AA No.1 were short range gun laying radars operating in the 1.5 m VHF band used to provide information for a anti-aircraft ...

British Army
The British Army is the principal Army, land warfare force of the United Kingdom. the British Army comprises 73,847 regular full-time personnel, 4,127 Brigade of Gurkhas, Gurkhas, 25,742 Army Reserve (United Kingdom), volunteer reserve personnel and 4,697 "other personnel", for a total of 108,413. The British Army traces back to 1707 and the Acts of Union 1707, formation of the united Kingdom of Great Britain which joined the Kingdoms of Kingdom of England, England and Kingdom of Scotland, Scotland into a Political union, single state and, with that, united the English Army and the Scots Army as the British Army. The Parliament of England, English Bill of Rights 1689 and Convention of the Estates, Scottish Claim of Right Act 1689 require parliamentary consent for the Crown to maintain a peacetime standing army. Members of the British Army swear allegiance to the Charles III, monarch as their commander-in-chief. The army is administered by the Ministry of Defence (United Kingd ...

Fire-control System
A fire-control system (FCS) is a number of components working together, usually a gun data computer, a director and radar, which is designed to assist a ranged weapon system to target, track, and hit a target. It performs the same task as a human gunner firing a weapon, but attempts to do so faster and more accurately. Naval fire control Origins The original fire-control systems were developed for ships. The early history of naval fire control was dominated by the engagement of targets within visual range (also referred to as direct fire). In fact, most naval engagements before 1800 were conducted at ranges of . Even during the American Civil War, the famous engagement between and was often conducted at less than range. Rapid technical improvements in the late 19th century greatly increased the range at which gunfire was possible. Rifled guns of much larger size firing explosive shells of lighter relative weight (compared to all-metal balls) so greatly increased the ...

Air-Sea Vessel Radar
Radar, Air to Surface Vessel, or ASV radar for short, is a classification used by the Royal Air Force (RAF) to refer to a series of aircraft-mounted radar systems used to scan the surface of the ocean to locate ships and surfaced submarines. The first examples were developed just before the opening of World War II and they have remained a major instrument on patrol aircraft since that time. It is part of the wider surface-search radar classification, which includes similar radars in ground and ship mountings. The first ASV was developed after the accidental detection of wharves and cranes while testing an AI radar, air-to-air radar in 1937. For a variety of reasons, ASV was easier to develop than the air-to-air variety of the same systems, and the first operational use of the Mark I followed in early 1940. A cleaned-up and repackaged version, ASV Mark II, replaced it at the end of the year, but the system was not widespread until late in 1941. ASV was useful for detecting U-boats a ...

21st Army Group
The 21st Army Group was a British headquarters formation formed during the Second World War. It controlled two field armies and other supporting units, consisting primarily of the British Second Army and the First Canadian Army. Established in London during July 1943, under the command of Supreme Headquarters Allied Expeditionary Force (SHAEF), it was assigned to Operation Overlord, the Western Allied invasion of Europe, and was an important Allied force in the European Theatre. At various times during its existence, the 21st Army Group had additional British, Canadian, American, and Polish field armies or corps attached to it. The 21st Army Group operated in Northern France, Luxembourg, Belgium, the Netherlands and Germany from June 1944 until August 1945, when it was renamed the British Army of the Rhine (BAOR). Western European theatre Normandy Commanded by General (later Field Marshal) Sir Bernard Montgomery, 21st Army Group initially controlled all ground forces ...

Early Warning Radar
An early-warning radar is any radar system used primarily for the long-range detection of its targets, i.e., allowing defences to be alerted as ''early'' as possible before the intruder reaches its target, giving the air defences the maximum time in which to operate. This contrasts with systems used primarily for tracking or gun laying, which tend to offer shorter ranges but offer much higher accuracy. EW radars tend to share a number of design features that improve their performance in the role. For instance, EW radar typically operates at lower frequencies, and thus longer wavelengths, than other types. This greatly reduces their interaction with rain and snow in the air, and therefore improves their performance in the long-range role where their coverage area will often include precipitation. This also has the side-effect of lowering their optical resolution, but this is not important in this role. Likewise, EW radars often use much lower pulse repetition frequency to maximiz ...

Tactical Control Radar
Tactical Control is a term originating in the British Army to refer to a class of medium-range radar systems. They are generally used for controlling the airspace around a set location on the ground, sometimes a dispersed battery of anti-aircraft artillery or surface-to-air missiles, but they also found use as air traffic control systems around airbases. They generally have a high pulse repetition frequency and rotate quickly in order to provide rapid updates at the expense of reduced range. In the Army, these radars were initially grouped into the Radar, AA, No. 4 classification, with several Marks of such systems being used from the early World War II period into the early 1960s. The main purpose of these radars was to provide early warning An early warning system is a warning system that can be implemented as a Poset, chain of information communication systems and comprises sensors, Detection theory, event detection and decision support system, decision subsystems for early i ...
