Our military stuff is hardened, probably everyone elses, ditto. I expect it to out survive us.
Exactly how is that cosmogenesis measured from millennial data?

* Carbon-14 and Berylium-10 are created from cosmic particle bombardment of the upper atmosphere, and follow the 11-year solar magnetic cycle variability.
* Sampled lavas will reveal magnetic flux magnitude and lines of flux orientation at the time of freezing.
* And radioisotopic dating will provide their age.
* There are 50- dating techniques available to scientists, which include radioisotopes dating to the creation of the solar system.
