A thrust vectoring variable geometry exhaust nozzle for gas turbines, which includes a convergent section (2) followed, in the direction of the flow, by a divergent section (3), both formed by master (4 and 5) and slave petals (41 and 42), whose convergent section (2) defines a throat (15) having a variable area. The divergent section (3) has variable geometry in order to orientate the thrust, and includes a governing and external radial support system for regulating the throat area (15), and a governing system for regulating the vectoring of the thrust. Both system are formed by a single governing system consisting of three annular pieces (6,7 and 8), concentric among themselves and with the axis of the turbine, and by a plurality of linear actuators (9). The master petals (5) of the divergent section (3) are transversely subdivided into at least two segments (5a, 5b).
