Having got the Moskva legendary upgrade (for slot 6) I've been trying to get a build for it, I hate losing turret rotation speed, so at the moment I'm trying this, but any other suggestions muchly appreciated...
Upgrades:
Slot 1 - Main Armaments Mod 1
Slot 2 - Surveillance Radar Mod 1
Slot 3 - Main Battery Mod 2
Slot 4 - Steering Gear Mod 2
Slot 5 - Concealment System Mod 1
Slot 6 - Heavyweight Main Battery Guns (LU)
Signals:
November Echo Setteseven
Mike Yankee Soxisix (replaces secondary performance from ASM1)
November Foxtrot
Sierra Mike
Juliet Yankee
India Yankee
Capt Skills: Viktor Znamensky - currently 19 points
Priority Target
Preventative Maintenance + (-45% module incapacitation)
Expert Loader
High Alert + (-20% consumable reload time)
Expert Marksman + (+1deg/ sec traverse speed)
Adrenaline Rush
Superintendent
Basics of Survivability
Concealment Expert
Net result from LU + MBM2 + Mike Yankee Soxisix seems to be; 2% better turret traverse, 4% better main battery dispersion (than if ASM1 was mounted), 8% main battery range gain, no loss of secondary performance (Moskva doesn't have torps anyway). On the downside main battery reload increases by 5% from 10.3 to 10.9 seconds, as a result of MBM2.
