曙光女神（Aurora，據稱其正式編號為SR-91 Aurora），為美国航空界和军事界最负盛名的传说之一，據說此機種為美国研发的高超音速侦察机。目前外界推測曙光女神最高时速可以达到6倍音速，飞行高度达到了3.88万米，在1980至90年代服役取代日漸老朽的SR-71黑鳥式偵察機。英國國防部在2006年6月的報告指出美軍在生產計劃優先順序中計畫生產速度4~6馬赫的極音速偵察機[1]；2007年9月，美國空軍與國防高等研究計劃局簽署諒解備忘錄[2] ，內容為製造最高速度可達六馬赫的無人機，此台無人機的名稱為Blackswift。但美国军方至2006年一直否认它的存在，虽然大量航空爱好者目击或拍摄到可能是曙光女神的形象。
