Declassified spacecrafts and orbital weapons of the USSR (2018)
Not sure how much I trust this page but if you are interested in an alternative history version of the space race I highly recommend For All Mankind on AppleTV+! It's a great show IMO. It shows what might have happened if the USSR beat the US to the moon and the Space Race never ended. It kicks the US into high gear and leads to a more advanced and in my opinion better USA (more liberal and technological/focused on Science). It's a biased towards a progressive viewpoint (so am I so it works really well for me).
