1: Gunners work on the ship, Reps and Restores on T slots and Support Slots, Engys only on Support slots.

2: To detect  SS once Submergedyou need a Sonarman and don't overheat or else you'll lose contact.

3: One learn the GA (Golden Angles for your guns) On the Brooklyn I cant remeber if it has enough room for Dual Guns on the brooklyn, but not all the T slot guns are single slot.

A: Brooklyn is believe you have no space for Dual guns on the T slots so you put the triple guns on the R slots and have it be a pure AA boat.  

A1: The Balitmore can put Dual guns on its T slots.

B:  The AA guns i use are the L24 D 5"/38 cal Mark 38 D. The Golden Angle for that gun is 40 Degrees

4: The alaska is a good AA ship but your main role is a BB so try to help your team and It can fit Dual Barrel  AA guns

4A: I can't remember if they have changed anything in NF since i left but if I remember correctly you want reload gunners, but i think AA gunners at high Levels are fine

I hate to be a killjoy, but don't forget that AA-only BBs are illegal as they don't "contribute" like other BBs. Make sure you have main guns if you're going to AA as a BB

it is easier to just use reload gunners as AA with US. if you class them to AAW (which is the little machine guns on all ships ) you will lose the reload for the gunners.

the lvl 18 3 inch "D" dual guns with 1.08 reload work good for US. the angle is 39 for planes at max altitude.

stick some HH in the main guns a sonar in the support slot, and be an AA, ASW ship.

if you need some help with AA find me in game and I will do what I can to help you out.

Best tip for US AA- turn off the red guide lines in your settings. use the green (normal guide lines to aim at the shadows of the planes.

a little practice and some timing and you will get it

A scout will help your team win also.

AAing with alsaka or guam is not a bad idea, this is a damage based game tho. just pay attention and you can switch to the main guns and hit some pretty big ships when they are blind or rushing. think about the other teams AA and ASW ships also. catch a couple AA boats that slip out a bit to far and CV will love you.

(it will not let you enter a GB room with out main guns on a BB)

any idea how to improve spread,i'm having really bad spread with my  BB3 right now,my main gunners are elite acc,class Acc-rld-rld EBVE lvl 90,but seem like with 16" gun 45 angle the speard really bad

US gunners will get better as they level up usually around mid 90's while using iowa. since your gunners are elite have you also "boosted" them? that will help exponentially as well as making sure rookie sailors have been converted to experts either by purchasing expert packs or AAing and getting experts that way.

as well its also best to convert expert sailors to veterans (100+) read teh user guides available on these forums for vetting and experting sailors as this will help with your gunners as well as your support crew

As for USBB's, all the BB's (BB1-BB3)  do not have good spread to begin with. it will not be until BB4 almost BB5 around mid 90's that us gunners start to block with the lvl 93 guns available and preferred for Iowa, and lvl 100 guns available and preferred for Montana.

unlike UK which block shots (shells clumped into a small group) by the time you reach BB3 and stay that way through BB6
