this next one ill be going with simple set ups
first I'll go over what all the icons mean

Starting from the left column down and to the right column down
Health
Armor
Evasion
Plane slots
Speed (to distinguish a fast fleet vs slow)
Range
Firepower
Torpedo
Anti air
ASW (antisubwarfare)
Line of Sight (used for branching later and recon phase at start of battle
Luck (if 30 use luck based cut ins (3 torpedos))


starting off with destroyer set ups

red red green is a good set up because this isn't luck based and it allows double attack
and cut ins.

this allows a small chance cut in at night battle.

a high luck destroyer like Shigure or Yukikaze would equip torpedoes on all three slots for the night battle cut in.

you can also take a wildcard like starshell searchlight or radar.










similar to the first set up, this uses two high angles with a wild card. cannot cut in at night but can carry the night battle equipment.

If up against subs, you should take two sonars and one depth charge.

you will get a bonus if you combo depth charge with sonars.











Light cruisers:

This is probably the most used setup of red red plane.

you can swap these out for the setup above if you are against subs.

If you have a four slot light cruiser like ooyodo or yuubari, you can add an extra torpedo, radar, night battle equipment, asw equipment, etc as the fourth slot.

ooyodo kai also has 30 luck so you can put 3 torpedos on her.



Heavy Cruiser:

red gun, red gun, plane, wildcard is the most common setup.

wildcards can be: 

Type 3 shell (good against installation boss)

Searchlight/Starshell (night battle equipment)

Torpedo (luck based mixed cut in)

15.5 yellow (cut in at night battle)

For high luck CAs like Myoukou, you can equip 3 torps on her.

For Maya kai ni, she will come with this concentrated 25mm and an anti air fire director (aafd) which allows maya to do an anti air cut in.

I have a 12.7 high angle with an aafd installed.

For a cheap cut in, use the 25mm concentrated, AAFD, and a high angle. The last slot is a wild card slot.

CAV (Aviation Cruisers)

Aviation cruisers are the same as heavy cruisers except they are able to help with air superiority and can hit subs.

Red gun, red gun, bomber, wildcard is the most common set up.

The only thing is to be careful of their plane slots.









Battleships:
Set ups are the same for all but the type of gun they use can matter.
Kongou, Fusuo, Ise, Italian Battleships:

The usual setup of
35.6
35.6
plane (bomber if Fusuo/Ise)
AP Shell (or other wildcards like radar, type 3 shell, etc.)

On these classes of FBBs/BBVs, you want to use 35.6 because using 41 or higher will be too heavy for them and you will suffer some stats like accuracy.

Generally AP Shell is the way to go but if you don't have any, you can use radar.













Nagato, Yamato Battleships:

The difference here is that Nagato/Yamato class can use 41cms.

Except on Yamato class, you are able to equip 46cms.










Carrier setups are a bit strange but this should be a general set up.

Pay close attention to the plane slots in the red box.

Fighter
Fighter
Torpedo Bomber
Dive bomber

Is a good setup for a carrier.
Torpedo bombers help in the opening phase of a battle, dive bombers helps a carrier's damage when attacking, and fighters shoot down enemy planes.

When using Souryuu, Hiryuu, or any CVL, you can equip Saiun (yellow plane) into the slot with the least amount of slots.

CVLs are generally used as Air superiority carriers so I have a Saiun for utility, dive bomber for attacking, and two fighters for AS (air superiority).
