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 ...

Radar, Gun Laying, Mark I, or GL Mk. I for short, was a pre- World War II 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.
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 SCR-584 (short for Set, Complete, Radio # 584) was an automatic-tracking microwave radar developed by the MIT Radiation Laboratory during World War II.It was one of the most advanced ground-based radars of its era, and became one of the primary gun laying radars used worldwide well into the 1950s.
The use of Director-controlled firing together with the fire control computer moved the control of the gun laying from the individual turrets to a central position (usually in a plotting room protected below armor), although individual gun mounts and multi-gun turrets could retain a local control option for use when battle damage prevented the ...
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.
Handguns and rifles, machine guns, anti-tank guns, tank main guns, many types of unguided rockets, and guns mounted in aircraft are examples of weapons primarily designed for direct fire. NATO defines indirect fire as "Fire delivered at a target which cannot be seen by the aimer."
