Have they been upgraded? Yes. Have they replaced those 1970s era engines with subs that have quieter electric drives as planned? Nope.
From the open letter (linked above) by the experts: "The last concentrated investment to modernize the triad came during the Reagan administration."
Even if you believe the subs are in great condition, that doesn't fix the other two fundamentally broken legs of the triad. The B-52 fleet would likely get shot down because they're very slow and non-stealthy. The ICBMs probably don't even work (no public evidence they do), they're in well known static silos, and have just a few minutes of "use or lose" time.
you do realize the ohio replacement class is literally in development right now.

They fire off a few randomly selected minuteman IIIs every so often and the footage is typically public. maybe not perfect evidence but it is some evidence.
