Re: KanColle Headquarter! Winter 2015 Event - Counter-attack! Assault on Truk Anchorage
EDIT: I can't sink the boss; no cut-ins/DDs go red before entering night battle. Tried an aerial support expedition but that didn't really help much. What to do what to do fuel is low and time is tight
Should I try changing fleet composition?
Depends what equipment you're running on your CV, if you're able to reach boss with the composition already then I would say stick to it, changing now won't guarantee you reaching boss node again, so you need to try all over again to see what send you to boss or not, it could also end up in a different route that you have trouble reaching boss with.
Shelling would be red planes right
Whether they do shelling/air support/torpedo support does not depend on the equipment you have. Torpedo is basically useless so no point considering it right now, Air support is basically if you have 2 DD 3+ CV(L) then it will do air support. Air support is great if you have a large amount of trash mob that needs taken out (generally one with low hp like DD and such) but they're generally ineffective against higher hp enemy as air support generally just doesn't focus on any target. Shelling just means anything that doesn't meet the Torpedo or Air Support Criteria will provide shelling support. Now that's when the red planes come in. Suiusei 12A x4 on a fully modernized Kaga will provide around 208 FP, and because Shelling support is pretty much purely dependent on FP, that's why people go red plane for support expedition (I don't even have a single 12A but I do however have a lot of other rare planes), however do note that blue also get scaled, I think only Green/Yellow doesn't actually do anything in terms of scaling with support expedition. However do note that Air Support is also effected by enemy AA stats, so in this case, your Air support is probably not doing much when it is being shot down by the enemy due to a decently high AA in E4.
If you do wish to read more in detail in regards to support expedition, here is the link:

Yep, divebombers for CV. And no more than 2 CV in fleet.
Please note that both Blue and Red scales, however red scales 2.0 and blue scales 1.5, which is why people might not use Blue if they have 12A. However if you happen to have good 4/5 star blue, they also do the trick.
I used support with 2BB, 2CA and 2DD. Always sinks 2-4 enemies, but huge waste of fuel.
That's really lucky o.O You'll be surprised if you tried Hard Mode that your support expedition won't even sink anything at all. However if they do, and when they actually hit the right target then they're really useful. But I won't quote on "Always sink 2-4 enemies" as this is very misleading, as much as shelling support do generally hit at least something when they arrive, the chance of them hitting depends on your morale, heck I once send a full 2BB 2CV 2DD (that's one of the most used set up at the moment if you have good planes) support expedition fully sparkled and they didn't even manage to sink anything at E5 Final Boss node. (though it did decent damage, it is actually sinking ships that counts, because therefore you've more chance of your Kanmusus hitting the right target then.)
