for tb
since the mn/sn patch is not yet patch in
MN got the best tb atm
(MN>RN>US>SN>IJN>KM)
but after the patch
RN get the title again
(RN>US>MN>IJN>KM>SN)

for DB
still MN lol
(MN>SN>IJN>KM>US>RN)
after the patch
IJN will gain the tile
(IJN>MN>KM>US>SN>RN)

for fp
i got know idea, they say US got the best fp

and i think the mn/sn patch is near

Actually,SN DB's will be SLIGHTLY better than IJN as far as damage goes...

FP
Ability wise
USN=MN>KM>SN>IJN=RN
USN and MN have +2 to FP as a national trait and another +1 for classing as Special Force.
KM has +2 as a national trait.
SN has +1 for classing as special force.
RN and IJN have no bonuses.

Tidbits:
IJN fighters are very fast making them actually better than RN and probably SN.
KM fighters are one of the slowest around but still pack a punch once they get to shoot things.
USN fighters have everything maxed.

DB bomb damage wise
SN>IJN>MN>KM>USN>RN
SN bomb damage is 10 points higher than IJN.
RN has the worst DB damage but tthe best TB damage.

Funfact:
in Korean NF KM DBs deal the most damage but the statchange for NFNA made them much weaker... they still have the worst TBs tho.

TB damage wise
Not sure but RN should be best and logic tells me SN has the worst... then again i'm not sure.

how about rm rangking position? pls advise

i think rm ft somewhere between km and mn

All the talk about ranking fighters and pilots is nice and exact science, but isn't everything that goes on during a game battle.

I run UK pilots, the dirtbag, tea-sipping woosie class of fighters.  However, I can take down all of the other nations' fighters. 

1 vs 1, the best pilot and best plane will most likely win. Not always.  If the best plane is slightly damaged, it may very well be the first of the planes to get shot down in a dogfight, not the weaker plane.  In other words, repeated encouters in dogfights weakens the plane (no repairman), and it can get shot down easily.

I've had plenty of squadrons eaten up, only to launch a quick 6 more and take down the enemy's hot T4s in a flash because they were already weakened by my fighters earlier.  Also, victory is in numbers.  Larger squadrons of planes inflict more damage and dominate zones.

ALso, if you run a nice set of +12 US FPs, what are your chances up against Boosted, Elite IJNs with 100 more vets?  Not much.  And until your boys reach L120, there will always be better pilots out there ripping your planes apart.  Don't rely too much on national traits, it's only part of the equation.

From my experience fighters usually oneshot each other (unless someone uses FPS below T3 with lvl 100+ pilots) so you don't really see many weakened planes unless you fly around ships at low alt for a long time.
