A uniplanar swivelable jet exhaust nozzle having duct sections which are serially and rotatably connected in planes oblique to their longitudinal axes. The first duct section is rotatably connected to support structure and peripherally carries a speed reduction train. The first gear of the train engages a motor driven ring gear extending around and carried by the first duct, and the last gear of the train engages a ring gear carried by the second duct section to impart torque thereto. A first gear of a synchronizing gear train, peripherally carried by the first duct, engages the second duct ring gear and a last gear of that train engages a ring gear fixedly carried by the support structure. Suitable connecting means are provided to drive the remaining duct sections.
