Interesting that you mention only domestic military facilities... When I was deployed to Afghanistan ten years ago, with rockets and mortar rounds landing daily inside the perimeter of our Forward Operating Base, I was irritated to see recent and high-resolution satellite imagery on Google Maps. I can see my sleeping tent, office building(s), and parked helicopters in perfect clarity. The imagery hasn't been updated since then, so you can still see everything despite this base being abandoned years ago. https://www.google.com/maps/@33.9428134,69.0629605,492m/data...

Do they need military-grade imagery? The Chinese or Russian militaries do because they’re trying to estimate war-time performance but I find it hard to believe that there are any domestic terrorists building sensor arrays to support SAM batteries. If they’re trying to blow one up, the resolution on a consumer drone or telescope would likely be more than enough.

Those generally avoid hardened targets like military bases.

It's 2021 (for another couple weeks) and everyone has access to imaging satellites with almost instant turnaround, for a negligible fee.

Consider yourself corrected.

Have you considered including a source that supports your statement?

Not OP, and no idea on pricing, but https://www.spymesat.com/new-tasking.html appears to allow you task a satellite selfie on demand

According to the pricing tab, it costs ~$20 to get a 1 km2 area with a 30-50cm resolution.

And if you ask for a shot of the “wrong” coordinates, how long until a nice person with a badge knocks on your door?

Seems like an obvious kind of honeypot?

For my family's semi-rural home I'm seeing that I can buy 0.5m (500cm) imagery from the last year for $250. No historical images with higher resolution I can buy. To task a new a photo at 40cm resolution would cost $1,800.00 from KOMPSAT-3A. (and it'd be a 10km x 10km area)

I googled it and came up with multiple answers. Instead of demanding people prove their work, take reasonable statements in good faith imo.

But do such consumer services mask military targets? Probably yes.

Not all of them. Some of them just don’t offer photos of that area, even though they offer literally every other inch of the earth in at least SOME scan, a lot of these are missing.
