> Not really. There are already signs that the Russian military industry is in hot water now because there are no Russian semiconductor fabs that can supply the type of chips needed for anything beyond dumb ballistic missiles […]

I don't know what your definition of «the type of chips needed for anything beyond dumb […]» is, but – if I were to infer – all chips manufactured for military needs are the dump chips, be it in China, or in Russia, or in South Korea, or in the US etc.

Military does not chase cutting-edge, smallest nanometer manufacturing facilities nor do they look for fancy 3D stacked L1 CPU caches and alike, the ones we encounter in consumer tailored microchips (MC's). MC's produced for the military sector 1) are always several generations behind the consumer counterparts; 2) are slower; 3) get subjected to extreme and very rigorous testing, e.g. getting baked in specially designed ovens; 4) they come with hardened shells to later get subjected to irradiation; 5) likely something else. Surviving specimens make it into missiles and elsewhere, for all is required for a missile is a chip that will be guaranteed to not have failed a mission.

Freescale (ex-Motorola) and Texas Instruments are two of the largest MC manufacturing contractors in the US. They have separate lines set up for consumer and military needs, with the military contracts taking a priority. I can't be bothered to check whether Intel or AMD have clandestine US DoD contracts but it is safe to assume so. When Motorola used to manufacture their own MC's, they also had two separate lines for the highly sought after DSP's, 56k and 96k series. There were two versions, a hardened one (prohibited for export out of the US), and the consumer version (with somewhat more relaxed export controls for the 56k series but not for the 96k series). Tolerance specs of the hardened version were classified at the time.

Back onto Russia. To cut it short, it is a case of hypocrisy on both sides as propaganda has been busy working on both sides. Soviet Union (and later, Russia) has been self-sustained, self-contained and has been manufacturing their own chips since late 1960s - early 1970s with always prioritising military needs over the consumer needs. They have never chased the latest designs or developments, but their stuff has been reliable where required.

It is not easy to assess their current situation due to the information disclosure suppresion and also due to prior reports of embezzlement on a unfathomable scale having taken place in Russia specifically when it comes to military contracts. What it is known with a fairly high degree of certainty is that Russia had commenced a 90 nm manufacturing facility as early as 2014[•]. There have also been sketchy reports that they have since moved on to a 28 nm process. Finding a reliable source is not easy, though.

Either way, chips that have been produced to a 90 (or 28 nm) process and have been subjected to hardcore testing requirements are good enough to drive missiles (likely, other military equipment too). Provided chip manufacturing facilities are still operating in Zelenograd, their output will be prioritised in the current political environment, and it will receive a priority funding in the local currency. One ought not to underestimate the adversary and ought to be wary of the creativity they may come up with once having been cornered.

Emperor Poo of All Russia has been demonstrating the world that he is willing to drive his never be, imaginary empire into the ground at any cost – in order to fulfil his ultimate wet dream of crowning himself as the first Galactic Emperor Poo, and, since Russia has been making their own silicon wafers, the MC manufacturing situation is not all that black or white – until more is known for sure.
