LOL. Of course we do. Tungsten rods the size of telephone polls dropped from orbit with an impact speed of about Mach 10. Its old tech. Weve probably had them for about 30 years.
No we dont.
1) It was an interesting concept but, like all things space, very expensive.
2) If you know anything about orbit mechanics you would know you cant be everywhere all the time and orbit revisits could be many hours to a half day.
3) gravity alone doesnt get you Mach 10, in fact the speed slows down to a few hundred mph due to atmospheric drag
4) with hypersonics we can get there faster with sub orbital systems than waiting for proper orbit geometry and that (hypersonics) is the next tech
5) having systems based on the ground keeps cost down, lets you upgrade much easier and cheaper, lets you test easier.
You can believe some old copy of popular mechanics if you like, but we dont have them. We may have prototyped the idea during the Cold War under Reagan, but certainly never operationalized.
Ive explained this in the past. If you could drop anything from orbit and hit the earth at Mach 10, then we would all be dust from the meteor strikes that bombard the earth routinely. The atmosphere slows and oblates all those rocks. But you would have to understand some real atmospheric physics to know this.
I live west of nowhere, near places not on the map and have seen stuff flying slowly and majestically overhead in the dead of night when normal people are sleeping, that would make most people faint...or claim they saw a “UFO”.
We got stuff.
Bet on it.
I smiled and waved and watched it glide out of sight.
