Moskva Sub Brief Research continues into May 2022 (Patreon)

I've been working on the Moskva Sub Brief for about a week now.  Things are moving along, I have a few rare photos that I will post here with this update.

One new obstacle is Russia has cut off access to some of the websites I use for the Russian perspective on the engineering and operations of these systems. I'm using more traditional 'Western' sources including a paid service for this Sub Brief.

Enjoy these photos while I finish the Moskva Sub Brief.  ETA early May 2022
