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 aimed directly ...
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 ...
One of the first successful fire-control radars, the SCR-584, was used effectively and extensively by the Allies during World War II for anti-aircraft gun laying. Since World War II, the U.S. Army has used radar for directing anti-aircraft missiles including the MIM-23 Hawk , the Nike series and currently the MIM-104 Patriot .
The earliest form of aiming point was a pair of aiming posts for each gun, almost in line with one another when viewed through the gun's sight, and placed about 50 m (160 ft) from the gun. There were at least two ways of using these, but the simplest is to aim the sight midway between them.

Gun laying is based on calculations of the range and azimuth of the target relative to the gun position, without the need for ranging shots (or adjusting) or even observation of the target. Ranging shots take time, and alert the enemy both to the presence and position of the guns, and to the likelihood of an attack.
The operator of the scanner would select targets, causing the gun laying cabin to slew onto the right bearing. The operator would then find the target, and begin a lock-follow. From then the data from the radar was sent into a predictor in the same cabin as the gun laying radar, which in turn controlled motorized systems on the guns.
