Any serious coast artillery will send her away, but she'll probably stand up to field artillery:

As long as you don't mind using CDS tonnage on such things, it looks fairly good.

I'd have simmed the 130mm guns as 'quick firing'.

I plan to use Russian CDS tonnage to build:

2x ~8,000 ton monitors with 4x 305mm

3x ~6,000 ton escort cruisers with 6x 234mm

3x ~1,800 ton bombardment ships, either with 1x 305mm or 2x 254mm.

and maybe another 1,000 ton bombardment ship with 1x 254mm, just to use up the remainder

That should usefully reinforce coast defenses, safeguard Russian convoys from surface raiders, and give Russian armies a bit of extra punch when reducing fortifications along rivers.
