Yeah, like I'd 100% wager there are more NORAD-like sites and that the Greenbriar has been replaced with at least one new site, but for the most part America's military strategy at this point is mostly about maintaining imperial hegemony rather than doomsday prepping. In the event of a nuclear war the monsters responsible certainly have their holes to hide in and enough military infrastructure left to give them a hope of ruling over the ashes, but I can't imagine the broader military has anything but a "get as far away from known/likely targets, wait for the dust to settle, then regroup" plan for most of its personnel (apart from hardening gear against EMPs and using APCs and IFVs that at least ostensibly would protect from nuclear fallout and maybe even blasts provided they were far enough away; I know hardening against fallout and bio/chemical weapons was part of the design requirements for Soviet IFVs, and the US copied the fundamental concept of an IFV from them), and that's if the plan isn't just "keep doing what you're doing, even if that's mopping floors or doing logistics paperwork, right up until the bombs fall directly on top of you because you work on a base with a publicly known location," which wouldn't surprise me either.
They also don't need underground bases for secret shit when just building a bigass hangar in the middle of a desert accomplishes the same protection against aerial/orbital surveillance at a fraction of the cost.

But think of how neat an underground city would be, it'd be like Black Mesa from Half-Life!
Or NERV, from the "get in the fucking robot" and orange drink show.
I think the russians did have one. Like, I remember hearing about it. I just have to remember if it was real, or propaganda I forgot the origin of.
