The invention relates to a canard fin unit intended for guiding artillery projectiles (1) fired on ballistic trajectories, which comprises a number of identical canard fins, deployable from a first passive, retracted position into a second active position once the projectile (1) associated with the fin unit has been launched from the barrel from which it is intended to be fired, the canard fins (3a d) in the active position being individually controllable. The invention resides in the fact that each canard fin (3a d) is individually supported and controlled in its own swivel arm (6a d), extending in the longitudinal direction of the projectile, which arm is in turn pivoted about its own swivel shaft (7a d) arranged transversely to the direction of flight of the projectile, the swivel arms (6a d) of all canard fins (3a d) being moved together from the retracted to the deployed position by one and the same operating element (10), displaceable in the longitudinal direction of the projectile. In an especially preferred embodiment of the canard fin unit according to the invention the said fins (3a d) are each coupled to their respective control elements (8a d), 9a d), 24a d) only when they reach their respective deployed positions.
