The main guns do 4 damage with 1 % chance to hit at their 380k km max range and 5 damage with 17 % chance to hit  at decent 300k km, against slow targets. Archer S04 offers 38 % chance to hit or higher at 200k km range to those twin 20cm turrets with 2 damage per hit, against targets at up to 20k kmps. Gauss turrets are meant purely for final defence fire. Note those 20cm turrets are bit armoured, bringing total HTK to 223.

Iranon:
While not as flavourful, I think you'd be better off with 15cm lasers, which are a perfect match for your capacitor tech. I'd also run a single ECCM system, it's rare that you need ECCM and split fire. Generally, you have a lot of overhead in electronics.

Detros:
15cm C6 lasers are going on the new version of 15kt Tarthanac which will make him an area defence cruiser. Uranami as a battlecruiser was supposed to have range advantage against "normal" cruisers with assortment of 20cm or 15cm lasers.

As a variant I was trying to put few 15cm C6 lasers here too but ended with 3rd turret of 20cm lasers instead. The need for more power plants was just taking too much space.

I was planning for 2 ECCM modules, one for each of those Gauss cannons, but I ended with one HS left and didn't figured better use then those small craft ECCMs which I have just researched. They may be used mostly with the main guns.

I have checked against my other military ships: ~25 % of cost in BFCs seems normal to me. I am looking towards that lowering of their price to by a third in C# Aurora.

see 2 spinal lasers main gun.   Its a not good for shielded enemy. Maybe better use one laser maingun and one meson (or another) maingun ? Or implement more twin 20cm laser turrets instead all spinal maingun ? 
two 2x20cm UFL turrets with ROF 10 and TS 16000  are much better than two 38sm Spinal UFL with ROF 35 and TS 8000.  And max speed 4600kms of your battleship is too low for active hunting with energy weapons.   Need twice lighter and twice faster (10 000+ kms) ship.

Detros:
I guess at this level 4600 is not the best hunting speed but so far I have seen only 2400 at other ships. Uranami is not really meant for hunting nevertheless, rather to pack big punch against PDCs, spacestations and smaller beam combatants that try to come closer.

I have doubled the spinal weapon so that I can have 2 BFCs for it (in my reservist strategy). It makes bit more sense to me to try to have both of them of the same calibre in such case. It seems to me for spinal-advancedspinal combination of basic lasers there is only 38cm one though there are some other pretty close ones.

I have more 20cm lasers on my destroyers of Surgat class. I have no research done towards meson weaponry.
