@michaelcoyote @osinttechnical GPS was built for ICBM navigation; one of the great Cold War unintentional innovations.

Thirty years after initial full operational capability, the intended-to-be-enabled smite button has been downscaled and widely deployed.

180000 tungsten spheres wrapped around 50 lbs of PBX delivered to within a meter or so? @osinttechnical
@michaelcoyote @osinttechnical I doubt that was tungsten spheres; likely the M31 unitary warhead.
@graydon @michaelcoyote @osinttechnical GPS wasn't built for ICBM navigation, they've used inertial since day one. Modern missiles can supposedly take GPS into account, but it's easy enough to jam that they still have full inertial navigation onboard.

@necedema @michaelcoyote @osinttechnical SLBM and (at the time, planned) mobile ICBM launchers benefit greatly from knowing just where they are on launch, and that was the original justification for the stonking price tag of the GPS constellation.

Then it became the world's clock and a US national technical asset, but in the beginning, it was so the missiles would know where they were on launch.

(Also, jamming GPS at the peak of a strategic ballistic missile's trajectory is non-trivial.)

@osinttechnical Welcome (again) to Mast! Good to see you here. Thank you for posting!
@osinttechnical very glad to see you over here.

@osinttechnical

That surely shredded some orchestra.

@osinttechnical I didn't expect the rockets to be hot enough to glow in IR. Seems like a drawback tho.
