The utility model provides a fire gun follow -up control device, including the main control unit, control the handle unit, install in second direction induction system, the fire gun drive unit of fire gun, install in operating handle's first direction induction system, the main control unit is connected with first direction induction system, second direction induction system, fire gun drive unit respectively. Its directional deviation through detecting first direction induction system and second direction induction system, motor among the control fire gun drive unit rotates, make the sensing of fire gun consistent with operating handle's sensing, reached and controlled action and the synchronous linkage of fire gun angle of adjustment, realized indicating which target which beat, overcome in the past at the car, the bad places of sight such as ship cockpit, operating personnel is difficult to learn in real time that the fire gun sprays the defect of position and angle, the efficiency of the operation of fire gun is greatly improved.
