A deployment and orientation device for projectile control surfaces, the deployment being carried out by means of springs between a loading position in which the control surfaces are folded inside the projectile and held against the action of the spring means using blocking means, and a deployed position in which the control surfaces may be oriented with respect to the projectile, device wherein it incorporates motors ensuring firstly the deployment of the control surfaces and secondly their orientation, the blocking means for the control surfaces being single means ensuring the immobilization of all the control surface and enabling them to be released simultaneously, the blocking means being immobilized by first locking means released by the pivoting of the bodies of the motors.
