A vectorable nozzle for directing the thrust produced by a gas turbine engine includes a duct, at least one toroidal nozzle segment, and a carrier ring for mounting the nozzle segment to the duct. The nozzle segment is hinged to the outer circumferential surface of the carrier ring about its toroidal axis. The carrier ring is rotatably mounted to the external surface of the duct at the downstream end thereof by means of a roller element bearing. The arrangement is such that the nozzle segment is moveable between a stowed location within the airframe space envelope and a deployed location. Once deployed the carrier ring is able to rotate the nozzle segment relative to the duct in order to vector the thrust produced by the engine.
