Wow, did you discover that by yourself? :P

(you can also run a 120 engineer on your BO slot)  

I'd say, better late than never :D

I am sure this is no new discovery but I did find out about this myself. Before I was driving an AA Emdan which runs out of ammo really fast. Now I can spam KM40 all day long. And those 5" shells usually kill with one hit.

I am looking into the possibility of doing this on a BB. But I cannot find a suitable AA platform in this class of ships. May be CVs can work? Haha.  I want to be a tank AA ship.

Honestly tho. I shoot down about the same number of planes on this ship as on my CV Implacible. On CV I mainly shoot down fighters but on Moltke I shoot down bombers. The credits isn't as great but the number of kills is really satisfying. Plus, its a lot of work running a CV.

 

If you're going to make any km bbs a dedicated aa ship better staying at moltke you'll just be wasting bb slot

It kinda depends on what room type you are playing. I am pretty sure that when you are playing a moltke in Blitz without R slots that it is kinda useless...

All KM BBs have great AA spots. I advise you to load the level 30 AA guns on your BB1-4s and the level 42? on the 5-6s. The point of having AA on your BB is give cover to yourself and your closeby teammates. 

It used to be handy to blind the enemy with it, but wouldn't trust to much on it with all the bugs/desyncs and subs. Had it very often that I killed all scouts in my surrounding, knowing that there is no sub near me, and that I somehow catch three full hits from the enemy *_*

I still use my AA to kill all kinds of planes nearby, but I am not going to use its "advantage" anymore. A last tip is to keep in mind that you are battleship and you ll be fine.
