By the late 1980s, many aerospace industry observers believed that the U.S. had the technological capability to build a Mach 5 (hypersonic speed) replacement for the aging Lockheed SR-71 Blackbird. Detailed examinations of the U.S. defense budget claimed to have found money missing or channeled into black projects . [ 8 ]

The Aurora (supposedly called the SR-91 Aurora) is a possible surveillance aircraft. No one knows if it ever existed. Supposedly, it was meant for trying out hypersonic flight, or speeds above 5 times the speed of sound. The name "Aurora" was used for the aircraft because in 1985, it appeared on an American military funding list.

美国曙光女神侦察机（Aurora，据称其正式编号为SR-91 Aurora），为美国航空界和军事界最负盛名的传说之一，据说此机种为美国研发的高超音速侦察机。 外界推测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。
