I seriously doubt it, I read the space-x job postings a while back, they are low low low cost equipment (they had every bean counter red flag known in their job listings, its probobly a stressful place to work). Piggy backing expensive military hardware on those soda cans would be a waste of money
more then likely, what they would allow for is OPFOR playing with them , that is give access to the regular sats for possible experiments / war games / hacker games, i.e. test jammers, virus/malware, etc. Stuff that requires access and "user time" but is non destructive. The only provision I can see them installing that would be secret on the behest of the government is some kind of kill switch, but that is a double ended sword (back doors that can be exploited by your enemies) and
very paranoid... more then likely installing shutdown back doors would be giving your enemies way more power over you, it would be a holy grail for a hostile country to find access to that. The proverbial self destruct button (space balls).. and even the war games are pretty dangerous, since its a commercial venture that effects the economy, the last thing you want is your stock to go
down because you made provisions for some idiot that wanted to play with a virus (reminds me of the sg1 episode avenger 2.0 )
I am sure his network is a barely functional nightmare and requires tons of effort to keep running at all, I doubt there is time/resources for shenanigans
i.e. right now GPS is making so much dollars that starting even a small war that threatens it would have such big consequences that any gains would be totally lost and piss off most of the people on earth.. it seems that all you need is a few successful quarters on the markets and most problems get settled lol. Even for a individual, like 3 paychecks later and you have no idea what you were even thinking before
IMO all the high end hardware that is interesting for the military (like say powerful jammers) is incompatible with the bare bones systems on those sats, you would need special antennas, improved power systems, cooling system provisions, heavier mounts, shielding etc. I think there is a lack of understanding of how much more involved the engineering is to add simple features in space, compared to putting it on a benchtop. The reason why space-x can afford 10000 of them in space is because their engineered down to the fractional penny. Those things are the hardest to modify
oh yeah, and if you make secret deals with the govt, and they some how wreck your stuff (i.e. say software/hacking experiments), then the ONLY thing you can tell your investors is that you are incompetent if you want to remain secret. Expect your stock to implode after that shareholders meeting, its full of rabid investors that bail out if you promise less then 1000% growth in the next quarter lol
Maybe a few of those sats have limited access by the military for limited / scrutinized experiments. I would not think it would go much further then this. But I think they would just buy it and keep it internal (why would you involve space-x at all other then tech support for secret govt research?)
The NSA obviously has a interest in them (much like ISPs), and I expect there is a room for them nearby, but they would just be interested in traffic, not the space part. The russians are using space-x terminals, its known, so its guaranteed the NSA is some how involved, just like they are involved for the internet in general... they would not be doing their charter if they were not
https://en.wikipedia.org/wiki/Room_641ABTW not sure if you worked with it, but bottom dollar hardware engineering (even for more advanced uses, like factories ,that need alot of something), is totally insane, when you first go there you run into ten "what the fuck, how could that possibly be a problem for this kind of system"'s in one week, when you realize that the design you had in mind for the system before seeing it is like 15 times more advanced then what they made (for cost reasons), and its generally a systems engineering nightmare, and later on you get literally excited when you determined its possible to fit another wire in the chassis if the assembler yanks on it, and its considered a engineering achievement, whereas external people would find it benign and pathetic
