A scramjet (supersonic-combustion ramjet) is a ramjet engine in which the airflow through the whole engine remains supersonic. The highest speed attained by a rocket-powered airplane, NASA's X-15 aircraft, was Mach 6.7. The fastest air-breathing, manned vehicle, the SR-71, achieved slightly more than Mach 3. The X-43A more than doubled the top speed of the jet-powered SR-71.
New Horizons does hold a speed record of its own, however, but it is much more specific than simply the fastest spacecraft.. New Horizons is instead the fastest spacecraft launched from Earth to date. In other words, New Horizons was traveling faster as it left Earth orbit than any previous vehicle launched into interplanetary space. New Horizons attained an escape velocity of about 35,800 mph (57,600 km/h) as it departed Earth orbit.
