EMP hardening is good news for the civilian population.
That raises the ante for the Russians to target direct hits on military installations since EMP will not disable them.
Not being mentioned, here, of course, is the quality of the Russian nukes.
They have more than us, but most are in storage and not mated to an active missile, SLBM or bomb. The numbers ready to launch on first strike are much less than the 6500+ they have. That also applies to our 5900+.
The question people have, is how much of the almost constant recurring maintenance has been done on them. It is very expensive. Since we know there is graft in the Russian high command, we must assume so for their nuclear forces. The vast majority of these numbers are devices inherited from the Soviet forces.
Furthermore, since nuclear has been very much on the back burner these past couple of decades, money diverted from this expensive task will not seem as traitorous as say, buying cheap, Chinese truck tires and letting them rot on the vehicle or real working ammo. But we know that has happened.
I can only speak to my knowledge of US military. I know in SAC (which is no longer a thing) missile maintenance was constant and inspectors were ALWAYS over your shoulder. I had a good friend, a B-52 cruise missile technician, who accidently dropped one off of a wing pylon and got fired. It wasn’t his fault, as he was working on a faulty release switch. The supervisors should have taken the ALCMs off first. But he still was resigned out of the nuke program and made a computer operator!
It’s a tough job. I’m sure the Navy has similar sop’s.
