Shared in hypersonic and missile threads as a compact, impressive overview of what Sprint achieved in the 1960s.
A short video on the US Sprint anti-ballistic missile, which accelerated to around Mach 10 in seconds under extreme g-forces and heat. It includes striking launch footage and a brief development history.
“It's a great overview of the development of the Sprint though, worth watching if it's of interest.” (HN, 2022)
You beat me to it! This timecoded link shows the launch sequence of the Sprint with a tracking shot of the vehicle itself. Pretty remarkable watching it start to glow white: [this video] I think this is the first video on that channel where the subject can match the guy's cadence. It's a great overview of the development of the Sprint though, worth watching if it's of interest.
Great overview of Sprint development with remarkable launch tracking shot.
Cool video of the (hypersonic) Sprint anti-ballistic missile, designed to intercept incoming ICBMs once they get below the ionosphere and are more visible to radar: [this video] It looks fake. I'm bummed I'll likely never see something like that in person...at least in a test.
Footage of hypersonic Sprint anti-ballistic missile launch.
On the subject of impressive old missile footage, I recommend the Nike-X program's Sprint interceptor-missile. Not hot glowing plasma on re-entry, but instead going up . As a short-range interceptor, Sprints were slammed up out of their silos via an explosively-driven piston, then they would ignite and reorient in midair, accelerating at 100g to reach Mach 10. The missile itself couldn't see very much, but would be remotely guided with strong signals from the launch installation. [link] [link] [this video]
Impressive footage of Sprint interceptor accelerating at 100g to Mach 10.
