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.

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.

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.

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.

When moving a save file I have somehow managed to load one that moved me back a year or two. Thus I have used slightly different path and Uranami now has 242 HTK and combination of 20cm and 15cm lasers, beside those double spinal 38cm ones and (now just dual) gauss turrets. Going with just 15cm C6 lasers would be too much demanding on power plants. Each of those FCs clocked at 16k will get one 20cm and one 15cm turret. Being a Flag ship it gained the first level of strategic Davidson sensor. Final HTK raised to 242. FCs are named so I later know which one is which in the battle log.

New fleet with half of dozen updated or new classes is in construction and still no enemies have been found.

Your Battlecruiser seems rather small to me but this is coming from someone who has mounted a 120mm spinal laser on a battleship that is exactly 60,000 tons.

120mm is 12cm. So was that the starting 10 cm laser which with spinal-ness raised to 12cm one :D ?
But yes, what is a cruiser for one is just a frigate for some other one. Bigger ships will come later though with this system my battleships would be at 30kt size.

I like the idea of using spinal and advanced spinal together to make a ship that can fire farther than common ships can and then using it to snipe the enemy. In wet navies, battlecruisers could run from battleships while pummeling cruisers freely, so that kind of build fits the old idea pretty well.

The problem is that huge guns don't give a range advantage in Aurora.

At extreme range, no single hit will be telling and battles will take time. This means continuous output is king, favouring weapons that fire every 5s.
15cm can be made to fire every tick without unreasonable tech investment (if you care mostly about extreme range, you'd research C6 before spinal tech or larger focal size), and they're a good match for the longest-range fire controls if wavelength and fire control range tech keep pace with one another.

For a classic battlecruiser concept (hoping to prey on ships both slower and shorter-ranged, avoiding equal or superior enemies), I'd recommend midsize lasers. With high speed requirements, tonnage is expensive; they want the most weight-efficient long-range weapon.
While not necessarily fragile, this type of ship tends to be expensive for its capability in a short-ranged brawl.

Large lasers have better armour penetration and shock damage, giving them the ability to achieve telling hits in the first salvo and quickly end battles at short and medium ranges.
They also allow reaching the maximum FC range with less wavelength tech; with smaller lasers we have to choose between cheap and long-ranged.
If tonnage is less of an object than cost-efficient raw power and we care about shorter ranges too, larger calibres have some merit... but to me that implies we're building battleships.

At equal technology levels, spinals can give you a range advantage.

Not realistically, because you're limited by fire controls.
