Jeff, where did you get your information?  Dwayne

Its been a long time so my memory may be wrong but I think the US produced a
missile, called the Sprint, that went 0->mach 10 in a few seconds. It was a
short
range, nuclear armed, anti-missile missile. If it was ever deployed it was
only
for a short time because the ABM treaty outlawed them. In the movies I've
seen of
its launch you cannot see it once it clears the silo. If the information in
Wikipedia is correct the top fuel dragster is much slower. Following is the
Wikipedia article:

The Sprint was a two-stage, solid-fuel anti-ballistic missile, armed with a
W66
enhanced radiation thermonuclear warhead. It was designed as the short-range
high-speed counterpart to the longer-range LIM-49 Spartan as part of the
Sentinel
program. Sentinel never became operational, but the technology was deployed
briefly in a downsized version called the Safeguard program. The Sprint,
like the
Spartan, was in operational service for only a few months in the Safeguard
program, from October 1975 to early 1976. A combination of high costs,
congressional opposition, and questionable efficacy resulted in a very short
operational period.

The Sprint accelerated at 100 g, reaching a speed of Mach 10 in 5 seconds.
It was
designed for close-in defense against incoming nuclear weapons. As the last
line
of defense it was to intercept the reentry vehicles that had not been
destroyed
by the Spartan, with which it was deployed.

The Sprint was stored in and launched from a silo. To make the launch as
quick as
possible, the cover was blown off the silo by explosive charges, then the
missile
was ejected by an explosive-driven piston. As the missile cleared the silo,
the
first stage fired and the missile was tilted toward its target. The first
stage
was exhausted after only 1.2 seconds, but produced 2,900 kN (650,000 lbf) of
thrust. The second stage fired within 1 - 2 seconds of launch. Interception
at an
altitude of 1,500 m to 30,000 m took at most 15 seconds.

The Sprint was controlled by ground-based radio command, which tracked the
incoming reentry vehicles with phased-array radar and guided the missile to
its
target.

The Sprint was armed with an enhanced radiation nuclear warhead with a yield
reportedly of a few kilotons, though the exact number has not been
declassified.
The warhead was intended to destroy the incoming reentry vehicle primarily
by
neutron flux.

Perhaps we are talking about manned vehicles?
