Abstract: A sight for an anti-aircraft gun, which is manually aimed, comprises a ranging unit, a gun-fixed aiming unit and a calculating unit, preferably a computer. The ranging unit comprises means for optical aiming at the target, and devices for determination of the range, the angular rate in elevation and azimuth, and elevation. The devices emit measured value signals to the means for optical aiming at the target, which means is settable in elevation and azimuth in relationship to the firing direction of the anti-aircraft gun. The calculating unit controls, guided by said received signals and information given about the velocity of the fired projectile and the prevailing wind vector, the second optical means in such a way that when the operator aims through same at the target by setting the barrel in elevation and azimuth, the offset and lead angles of the barrel are such that a fired projectile hits the target.
