In a cannon system, a change in the elevation angle of the cannon tube is converted to angular displacement of the yoke trunnions of the forward tripod support of the cannon tube. This angular displacement is sensed by a fluidic sensor which transmits a corresponding signal to a fluidic amplifier whereby the signal is amplified and transmitted to a cylinder for actuation of a piston therein responsive to the signal. The cylinder, piston and a piston rod form one leg of the tripod and the linear displacement of the piston acts to change the elevation of the tube to where it returns to the pre-selected angle of elevation as sensed by the sensor.
