The steering of a jet propelled flying body is improved by positioning jet deflector flaps into the propulsion jet for deflecting the propulsion jet. The deflector flaps can steer the flying body automatically in response to a flight control unit either alone or as a support steering system for the control surfaces of the flying body. The jet deflector flaps are arranged in the jet nozzle in a cross or star configuration and preferably near the periphery of the jet nozzle.
