Soviet Tier X cruiser Smolensk is a hypothethical realization of a MLK-16-130 (Small Light Cruiser, 16 130-mm guns) project of an escort ship armed with four quad dual-purpose 130-mm guns.
Basically, this entire ship is a controversy, for two reasons: she falls just a tiny bit short of having enuff dakka and she can use a smokescreen. Bonus points for her guns being 130-mm meaning Basic and Advanced Firing Training affect them.
I think it took me about half an year to finally get her. She's available in Admiralty for 244k Coal, and I decided to grab her first before WG removes her from sale or nerfs her.
