I can't really see how satellites will utilize 5G, 5G has extremely limited range:
"The shorter wavelength means 5G can carry a lot of data much faster than 4G, but it also means a much shorter range. 4G wavelengths have a range of about 10 miles. 5G wavelengths have a range of about 1,000 feet, not even 2% of 4G's range."
Using it from a satellite is a no go, as far as I see it. (LEO for satellite deployment is 2000km, 1000ft is only 0.38 km ), 5G is typically deployed using ground base stations hooked up to optical fibre, sure you can make a satellite base station that hooks it up to your LEO service mesh, but why? Satellites have very high latency due to the distances involved (ever seen a satellite call on tv? theres alway multiple seconds wait). The entire point of 5G deployments are that they are close by and offer extreme low latency enabling a whole slew of new techs (think AR, and proximity based sensor integration)
The article you link to on USAF using 5G states in the abstract:
"experiment with the capability to seamlessly move and share data among a wide variety of fixed and mobile operating locations using constantly available, high-bandwidth, beyond-line-of-sight communications"
This is basically what the military does today using a combination of radio, 4G and satellite communication, adding 5G to the mix doesn't magically make this more dangerous.
The CNBC article is basically a lot of bluster from the trump admin trying to cover over the fact that the US is starting to lag behind in telecommunications tech.
“As more autonomy moves to the edge of the internet of things, it’s going to have to be supported by more bandwidth,” he said, adding that space-based communications will play a key role in connecting 5G devices. “It would be a shame that if something that is going to control most of the data moving from machine to machine commercializes first overseas,” Roper added."
They provide no concrete plans for using 5G on satellites.
On SpaceX and their LEO satelite program:
US Air Force gave SpaceX’s Starlink program what, like almost $30 Mil?
So far that to me is nothing but a lot of hype, and the US government using the military to fund the oligarchs pet projects. I also fail to see how a service mesh will be faster than optical cables, since each satellite will add a routing and switching overhead.
On HPTSS aka "Missile shield" aka "Starwars":
Makes sense for the US to be developing this, probably an extension of their long defunct missile shield program, HPTSS is mainly intended to counter the threat from China and Russia's hypersonic missiles. As with everything regarding military spending take it with a truck load of salt, this shit is extremely difficult and almost never works out with how corrupt and inefficient US military spending is.
If you are worried about the US's ability to build a missile shield ask Saudi Arabia how valuable the Patriot PAC 2 and 3 systems they bought from the US were when the Houthis owned their oil refinery with like $3k worth of drones.
longer range means higher wave length means lower bandwith and higher latency, (as you said similar to 4G) I again don't really see how this is anything new or dangerous. Most of this post and these articles seem written by people who don't understand the tech.
The CNBC piece in particular is horrible its basically big boy military guy from the newly created space force fear mongering about china using 5g to steal their vitale essences and saying his space force will also use 5g like the air force does.
Sigh..

only mmWave 5G has low range, there is also mid band and low band (which is similar to 4G)
