There's a huge disparity between your missile ranges and your fire control ranges. Your missiles barely reach 17mkm while your fire controls see out to almost 300mkm. Unless your enemy can cruise around at 70kkm/s I would decrease the "to hit chances" of your ASMs, and put the freed up space into more fuel, or alternatively if your doctrine is " small range big bang" into more warhead. (the missiles the Gnevny uses are probably fine as they are if they are used against fighters, and those tend to be quite fast)
Your AMMs are fine, they are sort of "future proof" for when you decide to increase your AMM envelope to 10 mkm.
I would also put more fire controls on your missile ships. Even though your ships are quite well armoured, a single unlucky penetrating hit could essentially neuter your offensive capabilities. An other reason is to reduce the chances of overkill even if you fire missiles without sensors by dividing your firepower between several hostile ships (if you RP that your missiles have to have sensors then it's fine to have sensors, but fire control redundancy is still quite essential imho)
The Ognevoy and Gnevny does not have enough MSP to repair battle damage to the most expensive component (battle damage is max MSPx2 iirc)
I tend to design my ships (the exception being carriers) with half of the range you did, which frees up more space for weapons and such
Also your ASM Ships can only fire 3 salvos before they are out of missiles, which can be a problem.
But these two are more nitpicking than actual design flaws
These are the things I would personally change on these designs otherwise I think they are quite nice.
Enemy ships have observed ECM strenght 80, i don't know for sure will it increase or no, thats why all MFC's are way more range capable than missles (i still don't know what this "ECM" means in practice). And since they are 1HS - i don't thing that this is big problem for 20kt ship. But make them 25tonns and install 2 - is interesting idea : for now 1 enemy "Titan" class require full salvo of 2 Kirov's, maybe with 2 MFC's 1,5 Kirov's will be enough. Anyway for next ~2 years i can't do anything : Kirov's tied to protecting core worlds and i will not refit them until i will have spare 20 Kirov's to be able to rotate them.
MSP's of Ognevoy and Gnevny - thx i will do something about that.
Now all my anti-ship missles already done with sensors:
With future missles techs priority will be strictly warhead (Enemy "Eclipse" class : 25k speed , 262 150 tonns , 168 x 3 dmg lasers , 4 x 289 dmg lasers). For now only 1 observed and destroyed. (this one rolled over my 5 Kirovs that run out of missles)

About deployment and range: when i will have 2 full fleet's (i need ability to rotate them) i think i will reduce deplotment time to 6 months. Range : only if will create Military tankers that could operate with fleet.
Kirov's are capable only for 3 salvos : yes, this is a huge problem and i managed to provide only this solution for now:

This design is classed as a Military Vessel for maintenance purposes
Designed to operate within Kirov's Groups directly : 5 Kirov + 5 Priboy-MLT G8 in group. I will build 20 of them and test in future Kapteys Star offensive, maybe will build more if results will be good.
