A thrust vectoring exhaust nozzle system for helicopters includes a vertical thrust vectoring nozzle positioned on the rear of the tail of the helicopter and a horizontal thrust vectoring nozzle positioned generally adjacent the vertical thrust vectoring nozzle, the vertical and horizontal thrust vectoring nozzles each connected to the exhaust output of the gas-turbine engine of the helicopter such that by adjusting and controlling the vertical and horizontal thrust vectoring nozzles to direct gas outflow in a selected direction, the exhaust outflow from the engine can be used to assist or modify the movement of the helicopter.
