First of all. You made a good choice.

KM has good fighters and bearable bombers (their DBs are third place damage wise)

Since KM has very good fighters you should focus more on fighters than bombers.

5 fighters is a minimum in a CV5 (any less and you are either a BW or a nub),
If you want to do some damage you will want dive bombers 2-3 are enough when focusing on
fighters.

Just know that... KM CVs are both horrible and scarce. You literally get 3 CVs Seyditz,
Graf Zeppelin and Europa... and thats all you get untill CV6 (unless you buy the PCV).
Seyditz has CV1 aircraft space despite being a CV2 (KM has no CV1) and all other CVs have
less aircraft space when compared to their foreign counterparts.

PS. DO NOT use TBs. KM has the worst TB damage in game.
PS2. Your fighters should have at least 11 base in their fighter skill. Any less and you
gimp yourself.

go with 6FPs. 6 FP is better for rotate pilots...

KM have strong fighters and strong dive bombers. I would reccomend a balanced crew of 5
fighter pilots and 3 dive bomber pilots. You wont be able to use them all until you get to
CV5 europa but it is good to have them ready ahead of time.
