In the long run that could become a massive strategic advantage for the US. A 2nd layer of resilience over undersea cables

Real time video and telemetry for military drones that’s nearly immune to electronic warfare counter measures is the real end game. The fpv drone carnage in Ukraine is currently limited to the contact lines plus or minus a few kilometers. Satellite comms change that drastically. Yes it’s available now but highly restricted.

But not immune to missiles. Russia's already threatened to target Starlink satellites. Maybe they're bluffing, or not, but it does offer a reminder that these are just floating computers in the sky.

How feasible is it though once the network reaches a huge size? Starlink satellites are tiny, and they've been deploying thousands of them over the last few years. I imagine it would take enormous resources to shoot them down, especially if the US does treat them like a strategic resource and adds more for redundancy.

The huge size of the network is itself a risk. Kessler syndrome is something everyone is currently trying to avoid, but if you wanted to intentionally induce it you could just start launching giant payloads of tiny ball bearings into their orbits, or take down enough of them that the shrapnel becomes equivalent to that anyway. Starlink is low enough that the debris from even a full Kessler syndrome cascade will deorbit very rapidly, but we're still talking a 3-5 year timeframe, not months, and trying to rebuild capacity in that period will just worsen + extend the problem.

>>lucubr+rl6
This is something commonly misunderstood. Kessler syndrome is a statistical process that happens over many years. It is not a sudden cascade like is seen in movies like Gravity. Statistical processes are not what militaries are interested in.

It's actually thought that Kessler syndrome is kind of already happening right now, which is why there's a lot of push right now to try to de-orbit the very large pieces of debris, so they can't act to form further debris.

>>mlindn+Ox6
It happens as fast as it happens. Any actual projection would depend on the specific orbits, masses, volumes, materials, and numbers of satellites - Starlink's orbits have a lot of satellites now. There's a very big difference between "everyone trying to avoid it" and "one of the world's largest space programs trying to cause it" in terms of how much we should be worried about it happening for any given orbit in the near term.

The reason it's a scary outcome is because it's an exponential. It can look like an isolated incident or incidents, then the next day be not practically stoppable.

>>lucubr+HA6
There's already significant amounts of debris that transits through Starlink's orbit.

And I'm telling you, your "image" of what this looks like is just incorrect. The kessler syndrome is likely already occurring. Yes creating more debris will make it happen more, but it's not like lighting a match to a pile of tinder.

And it's not in fact exponential in the sense that people commonly imagine when they hear that. It's an exponential that's very close to flat, i.e. an exponential with an exponent barely above one. Given enough time, yes it can destroy all satellites in Starlink's orbit, but it's not on time scales that's relevant to a war.
