A plug nozzle is convertible to and from an open nozzle by moving several components. The convergent flap moves between an outboard convergent flap position and a central plug position. Divergent flaps, hinged to the convergent flaps, move between the outboard divergent flap position and a central contacting position within the plug. Plug surface flaps are moved to the inboard position where they form the plug surface from an outboard position.
