Yeah and that makes the SAM stuff easier. But there's other stuff to like ECM gear, air search radar, navigation radar, etc. You can scavenge quite a bit from the real Soviet drawings but stuff like railing can be in the way which bisects systems. They aren't labeled and so I've sometimes found it difficult trying to figure out what system is what by cross checking it with the Polmar books I have which lack a lot of pictures of Soviet ECM gear and radars. It's not a criticism of anyone just a few observations about the differences between parts sheets.
Yes, that's the other side of the coin. It's a much more challenging task than the USN side. If your library has any of Friedman's Naval Institute Guide to World Naval Weapons Systems
, that would be the best reference I can suggest.
