In an airbreathing propulsion system for a supersonic vehicle, the improvement which comprises: a body having an air receiving duct formed with a fixed cross-sectional area inlet opening from a side of said body and said duct having a converging throat spaced from said inlet opening and having a lesser cross-sectional area than said inlet opening; a propulsion powerplant communicating with said duct downstream from said converging throat to utilize the air flowing therethrough; and means carried by said body for maneuvering the body into a position for starting said duct, said maneuvering means including a vehicle body guidance means and body flight attitude control means, said guidance means being operative on said control means for positioning said fixed cross-sectional area inlet relative to the airstream flow over said body such that its area presented to the airstream flow is reduced for starting said inlet to supply air for the airbreathing propulsion system.
