Gun laying. Gun laying is the process of aiming an artillery piece or turret, such as a gun, howitzer, or mortar, on land, at sea, or in air, against surface or aerial targets. It may be laying for either direct fire, where the gun is aimed directly at a target within the line-of-sight of the user, or by indirect fire, where the gun is not ...
GL Mk. III. GL Mk. III (B), with IFF. Radar, Gun Laying, Mark III, or GL Mk. III for short, was a radar system used by the British Army to directly guide, or lay, anti-aircraft artillery (AA). The GL Mk. III was not a single radar, but a family of related designs that saw constant improvement during and after World War II.
Radar, Gun Laying, Mark I, or GL Mk. I for short, was an early radar system developed by the British Army to provide range information to associated anti-aircraft artillery. There were two upgrades to the same basic system, GL/EF (Elevation Finder) and GL Mk. II, both of which added the ability to accurately determine bearing and elevation.
Displayed in the Canadian War Museum. 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 ...
Range gate pull-off (RGPO) is an electronic warfare technique used to break radar lock-on. The basic concept is to produce a pulse of radio signal similar to the one that the target radar would produce when it reflects off the aircraft. This second pulse is then increasingly delayed in time so that the radar's range gate begins to follow the ...
The Automatic Gun-Laying Turret (AGLT), also known as the Frazer-Nash FN121, was a radar -directed, rear gun turret fitted to some British bombers from 1944. AGLT incorporated both a low-power tail warning radar and fire-control system, which could detect approaching enemy fighters, aim and automatically trigger machine guns – in total ...
The M9 gun director can be seen in the center background of the photo. The M9 gun director was an electronic director developed by Bell Labs during World War II. This computer continuously calculated trigonometric firing solutions for anti-aircraft weapons against enemy aircraft. When cued by the SCR-584 centimetric gun-laying radar and used in ...
In 1944, the US Army contracted [7] for an electronic "computer with guns, a tracking radar, plotting boards and communications equipment" (M33C & M33D models used different subassemblies for 90 & 120 mm gun/ammunition ballistics.) [3] The "trial model predecessor" (T-33) was used as late as 1953, [8] and the production M33 (each $383,000 in 1954 dollars) [9] had been deployed in 1950. [10]
