I agree with those Kirovs. They would decisively lose a Missile engagement with Mars and would never get into laser range where their weight of fire might make a difference.
I was wondering what design theme to use for the US/Russia faction, so I was reading a really good book I have on Soviet warships...

After reading the Kirov section, I wondered if I could really get everything onto a single hull. Designing ships is fun if you don't have to worry about actual combat effectiveness
Besides, with no real combat experience, they probably seem fine to the Jovians. Very large and threatening. I'm sure they will adjust based on combat experience
It seems you and me both do a lot of background research.
For my current USSR-campaign, I spent about a week going through the military structure and organization of soviet strategic missile troops (in other words; ICBM batteries), soviet army and soviet navy in order to make a believable OOB for ground troops and setting up the organization tab.
I've used them as a template in other short-lived campaign where I tried out the 1982 Able Archer scenario in a multiple-NPR earth start.
Keep up the good work and I really appreciate the way you keep things "realistic" in the context and play things out as anyone would best assume they would in such situations.
