I had this shower thought last night. If you had enough satellites in the sky, you could broadcast certain bands of radio signal from the ground and use the shadows and distortions between the broadcast and the receiving satellites as a form of radar to watch for stealthy objects; it would allow for brief moments of detection, along with approximate vector calculation. If those satellites were also equipped with moderately high resolution cameras, the combination would allow detection and tracking of objects at any altitude.
Russia defeated the F-117 Nighthawk with X band radar, and I think a lot of aeronautical geeks have since dismissed "stealth" as useless. It's definitely not useless. The Nighthawk relied, in large part, on its tiny radar cross-section, and the technology was very rudimentary at the time. Despite how wasteful the military-industrial complex is, especially during peacetime, the amount of money put into stealth technology in the ensuing decades, is not simply a matter of waste. The Air Force would not spend twice as much time and money for every flight hour, for modern jets, like the F-35, if the stealth was entirely ineffective.
A lot of folks see these satellites as the Internet for the CBDC or digital ID, and I don't deny that they could also be used for those things. But I think that the bigger use case is as military technology, for battlefield communications and observation.
Just ask yourself, if I can think of this, what are the odds that DARPA and the military industrial complex didn't think of this. I've come up with some reasonably interesting military invention ideas over the years, but I'm certainly no competition to DARPA as a whole.
This isn't really a "conspiracy theory", since the military has always been engaged in designing and developing and deploying secret technology, and, if anything, it's a little bit of a white pill that the US could have a new leg up on the rest of the world when it comes to tracking missiles and stealth jets (versus the timeline where these satellites only serve nefarious globalist purposes).
LOL, this honestly could be the most realistic explanation.
