    Sprint was the dragster version of an RV interceptor. The Wikipedia extract below highlights its performance...

    ======================

    The Sprint was a two-stage, solid-fuel anti-ballistic missile (ABM), armed with a W66 enhanced-radiation thermonuclear warhead used by the United States Army. It was designed to intercept incoming reentry vehicles (RV) after they had descended below an altitude of about 60 kilometres (37 miles), where the thickening air stripped away any decoys or radar reflectors and exposed the RV to observation by radar. As the RV would be travelling at about 5 miles (8.0 km) per second, Sprint had to have phenomenal performance to achieve an interception in the few seconds before the RV reached its target.

    Sprint accelerated at 100 g, reaching a speed of Mach 10 in 5 seconds. Such a high velocity at relatively low altitudes created skin temperatures up to 6,200 F (3,430 C), requiring an ablative shield to dissipate the heat. The high temperature caused a plasma to form around the missile, requiring extremely powerful radio signals to reach it for guidance. The missile glowed bright white as it flew.

    Wows ......6000 degrees. That's like acetylene temps. Mind boggling.

    Even more incredible was the fact that the Sprint inertial guidance system used mechanical gyros. Imagine trying to design a precision instrument in an environment where every drift-inducing imbalance will be exposed to 100 g accelerations.
