The Lockheed X-17 was a three stage solid-fuel research rocket to test the effects of high mach reentry. The first stage of the X-17 carried the rocket to a height of Template:Convert before burning out. The rocket would then coast on momentum to about Template:Convert before nosing down for reentry. The second stage engine would then fire before jettisoning and igniting the third and final stage. On April 24, 1957, an X-17 reached a speed of Template:Convert at Patrick AFB.[1] Ultimately the X-17 would be travelling towards earth at up to Mach 14.5.
The X-17 was also used as the booster for the Operation Argus series of three high-altitude nuclear tests conducted in the South Atlantic in 1958.[2]
