PROBLEM TO BE SOLVED: To provide a nozzle with yaw vectoring vane not complicated, not heavy, not expensive, and effective in vectoring. SOLUTION: An exhaust vane 26 disposed in a divergent section 13 of an engine exhaust nozzle 10 is sideways pivotable about a vane pivot axis 28 centrally located at an unvectored nozzle throat 18. Upper and lower tips sideways of the exhaust vane 26 with a space are incorporated into the upper and lower surfaces of a nozzle outer wall 23. The exhaust vane 26 has flat or contoured sidewalls 20. The sidewalls 20 are concaved. The exhaust vane 26 has upper and lower vane sections biased sideways from the upper and lower tips to extend inwardly. The exhaust vane may be articulated having upstream and downstream sections separately sideways pivotable about the vane pivot axis 28 and a second pivot axis 38 disposed downstream of and in parallel with the vane pivot axis 28.
