Personally, I prefer the pompoms on my battleships. They're light, fast firing and have a rather fast reload time.

On the carrier (Malta), I prefer the D version of the 5.25" RP12 guns. I load enough AA to kill incoming aircraft that get left at default height.

And some of the LHE ammo for those games where I find myself  having crappy teammates. I just shoot charging ships that are focused on something else. *cough* DDs *cough*

 

What level is "late" when classing AA gunners? Mine are currently sitting at level 78, as passengers. Do I keep going or is that far enough?

If you have 100 vets,boosted and full experts, you 'll get close to the reload cap at 120 if classed at 100. If you want to reach the reload cap for sure you'll either need to class later or get more vets.

Armament sailors aren't totallly useless though, HH might be worth carrying.

Use of pom-pom:
1. To kill bombers (range too short to kill scouts)
2. To make your enemy lag


Use of 5.25 AA guns:
1. To kill scouts and TBs


P.S. Try QV with 5.25 in WAW. I'd say the best BB6 in WAW. (low shell hang time + medium range + armor + great AA + great damage)
