Ok, you are all hitting close to bingo but no...
Lets look into the past a.k.a. history:
So Ise hybrids were to counter the lack of IJN scouting ability (IJN CVs weren't ment to be scouts like USN, and D3A1 Val was not such a great multitasking carrier aircraft as SBD Dauntless was). Why? Doctrine...
So since batle of midway, the IJN's aircraft carrier numbers gone low and nor the doctrine let them to scout for the fleet (ijn carriers were ment to be pure offencive weapons), nor IJN carrier aircraft could do this task well enough, IJN admirals started to see that fleet is becoming blind.
So old battleships, which by outbrake of WW2 became nearly obsolete and were reasigned to secondary roles, were supposed to fill this gap.
The plans were to convert them to aircraft carriers, but planners realised that there's no time for that, nor place to occupy shipyards man power on conversions when shipyards were busy with building new ships.
So Ise hybrids were born.
Already limited in offencive gun battles, they were ment to stay in secondary role, but also to scout for the fleet.

So, all this leads to (in NF terms) support battleship. 
Ok, what it actually means in NF?
A battleship who stays behind front line, but at the same time close to it, waiting for a chance to utilise it self via various tools it can fit: main guns, secondary/AA guns,  torpedo launchers, hedgehog launchers, scout/fighter/dive bomber/torpedo bomber aircraft.

Now lets examine what it already has and what it doesn't.
It has limited main gun battery, those shells hit hard, but not enough of them.
It has T slots for AA or torpedo/HH launchers.
And It has space for aircraft, which is limited.

So we have a platform which is offencive (main guns), but also defencive - T slots and aircraft (why aircraft are not in offencive part? because you have main guns).

Lets build something out of it's drawbacks.
1) Main guns,
2) aircraft - fighters (can provide vission)
why not DBs or TBs? You already have main guns for that.
3) on T slots HHs - ASW role
Why not torpedo launchers? Since you already have your main guns for dealing damage to surfaced targets.

So main guns for damage, fighters for vission and defencive abilities (remember, support ship) and hedghies for underwater threats.

Now since I already established that it's a support BB and support means nothing else than defencive the crew would be:
B.O., 1 main gunners (if 2 slots, then 2 gunners), 2 any armament sailors for HHs.
On support slots if 8:
3 engies, 2 reps and 3 pilots
if 9 support slots:
4 engies, 2 reps and 3 pilots or 3 engies, 3 reps and 3 pilots.

There might be more pilot vise crew build, but then spaces for main guns woun't be utilised, nor BB status would...

To sum up, it's obvious, that whatever your crew build will be, it'll be so damn hard to play and properly utilise this ship, same as all hybrids, but at the same time it has the potential to be the best EBB6...

The Ise CV has the potential to completely change the heart of the battle in typical GBs for its hybrid uses as mentioned. Because of its unpredictable variety of gameplay despite its limited capacity of resources, if you can skill focus one CV trait along mastering both capital ship perspectives with your current pilot setup and its 16" gunset with its smashing penetration, reload and damage, then I really believe this ship has much to offer which can really throw off the momentum of a battle situation unexpectedly to even some of the most skilled players in-game. An even better asset with coordinated and synchronized teamwork with other captial CVs. Don't forget that you can also utilize its T slots to your preference as well whether it'd be for ASW/AA work if needed.

It's understandable that not many others would use this ship since the majority are more likely eager to jump into the next BB tier, but to anyone who does enjoy the minimalistic challenge (playing conservatively with a set target) for everything the game has to offer with enough in-game experience, reach for this thing.

Atago is the funniest BB i ever played, well today i tried:
-4 Fighters Pilots    (38 lvl 115 fighters)
-1 recon                 (14x lvl 115 scouts)
-5 enginners
-1 gunner
-2 repairers
-BO Config

Fighters are prioritary for protecting the BB and shooting down enemy scouts, the atago only gets 37 knots, is a line fighter, I carry aprox 35 fighters and 15 scouts, scout is the best, fighters T5 has ver low fuel, figters can take off only 8, due that are more for protecting and weak enemy players like KM with his only for 4 scouts. Repairing was useless due the range advantage, I need to repair when the match was lost, but for the lolz I wanted to test T slot and for a bug u cant changge them, I recommend ( I  lost today from 5 matches 3 times due subs) :
 
-4 Fighters 
-1 recon
-5 enginners
-1 gunner 
- 2 HH gunners (5 turrets), or 1 HH gunner (3 turrets)  and  a repair man
-BO Config 


For the lolz
-4 Fighters 
-1 recon
-5 enginners
-1 gunner 
-2 Torpedo men with 5x m3 Launches like a kita 1313  ( 500 of shell space  (kitakami has 98))
-BO Config  

Well I still need to lvl my torpedo launchers from my sub :(. 

In few hours T slot problem solving patch will be applied.

Um your setup is decent, though i would run 3 engies and 2 reps, instead of 5 engies.
The point beeing - that overheat must be controlled even if you have epic engies (vet capped heroes).

If someone is wondering, it can load 118 of 115lvl scout planes.

And to add diversity, what do you guys think about 40lvl fighter interceptors on it?
You can have more of those compared with 115lvl fighters, with more offencive power, speed and fast loading time, but limited by fuel. 
For scouting you already have scouts...  

Not sure about if Agato can be the best damage-maker among all BB6/EBB6s, but surely it'll be the best win-rate maker among them all because of its extraordinaly supporting role (and perhaps the best 1v1 BB).

1 Recon + 2/3 Ftr setup guarantees that, when well-controlled, you can give sight to your teammates with no blackout time at all, and keep enemy blind and free your teammates from being bombed by enemy CVs. Use PHH on T-slots and an escort so no SS can harm you either. Oh and BB6 range, one can't really ask for more.

In reality, even a proper CV such as USN Enterprise (Big E) can only hold 60+ aircrafts. 35 Lvl115 Fighters and 15 Recons on this thing sounds way too overpowered. In my opinion, this thing should only be able to hold 20 Lvl115 Fithers and 10 Recons. Otherwise please make its size 1.5 times as big as it is now.

Okay folks.


I was the guy who primarily dealt with the Atago in testing. Simply because I made the hybrid sprite that kicked off the idea of making the Atago a hybrid instead of a straight clone. 



The ideal setups for the Atago were:
Without T-Slot Weapons:
x1 BO
x1 Gunner
x2 Rep (T Slot)
x4 Engineers
x4 Primary Pilots
x2 Secondary Pilots (Or Airlift)

With T-Slot Weapons:
x1 BO
x1 Gunner
x2 T-Slot (Gunners, AA Gunners, Torpedo whatever)
x1 Rep
x3 Engineers
x4 Primary Pilot
x2 Secondary Pilots (Or Airlift)



Remember, this thing is essentially a CV3 with a 30+k front salvo and BB6 range. I highly suggest not going below 4 pilots on this thing. 

OKay, can anyone tell me the exact lay out of the ship?

From what I gather, it is

1 BO

1 Gunner slot (controlling 3 guns)

2 T slots (1x controlling 6 T guns, 1x controlling 4 T guns)

10 support slots

is that correct?

Here ya go:
