 An electro-mechanical all-electric drive (AED) for weapons control with independent stabilisation has been developed indigenously by DRDO in association with private sector industry for the turret.The purpose of the AED is to position the 40 mm cannon on to the target in azimuth and elevation and to provide twin-axis turret stabilisation against external disturbances.The AED uses brush-less drives with especially designed backlash-free elevation and traverse gearboxes coupled to the turret ring for rotation in azimuth, and to sector gears for elevation/depression of the cannon, respectively.
