I think it still needs to be cleared out the whole thing about operating your CVs into big TFs or smaller ones that respect the coordination issue.
GJ, I want to cover that in detail and will try to observe all advantages and drawbacks of the two variants.
My question now is: for what concerns CAP (so let's forget for a moment about offensive strikes), does it matter to have several CVTFs in the same hex (also forget about the possible reaction for a moment) instead of one big TF?
There is a difference in CAP effectiveness, fighters from other groups supporting interception on a specific group will get the "xy is area CAP intercepting"
message, in combat animations, which suggests lower effectiveness.
Will the presence of several TFs in the same hex puzzle the attackers so to divert some enemy bomber strikes to different TFs (even if all present in the same hex)?
I am not sure I understand your question like you meant it. If you are asking if multiple CV TFs are more difficult to intercept than a
single CV TF: Yes, definitely. They got different DLs, and so different chances to be attacked. If a strike is launched against a single
huge CV TF this automatically puts all carriers you got in that hex under attack. I am aware that WitP AE allows the strike now to split
up against multiple TFs in the same hex, but that still does not outweight the disadvantages. The CV battle Mike (offenseman)
has been referring to was partly influenced by the fact that I had multiple CV TFs instead of one.
And for what concerns AA fire, is it better to have a massive CVTF with several BBs attached or more CVTFs with one BB each... so to say, given the same amount of AA guns in the same hex, does it matter for AA coverage to have it spread over multiple TFs?
An A/C on a shipping attack run suffers 3 AAA phases. First on ingress alt targeted by ships in the TF (obviousely if gun range is within ceiling alt), second on weapon release alt from the
ship under attack (IIRC in addition CLAAs in the TF can fire as well), third on agress again by the TF.
So, on first glance this makes concentrated AAA of carriers in a single TF the better choice, but only on first glance.
Because all CVs expend AAA ammo firing on aircraft not attacking them (from DP high ceiling guns), and so are later in a worse position
when under attack themselves. Also they do not aid in the defense with lower caliber guns like 40/25/20mm, as for example the 40mm Bofors - the
premier longer range AA point defense gun on USN ships - as it only has a ceiling of 9800ft. Usually in a CV engagement the ingress and egress will
be flown between 10-15k.
This leaves us with the large number of DP guns (e.g. 5in/25 Mk 10 installed on many USN ships, or the IJNs 5in/40 Type 89) for shooting strike ingress
and egress, and with regards to those there are a couple of ship types better or equally strong equipped as carriers which are also less vulnerable to
drawbacks from expending ammo not in self-defense, as they will not be primary targets.
So in case all multi carrier TFs get under attack, in total there are a lot more guns available against the strike as when concentrating the carriers
in a single large TF.
EDIT: I am aware that the solution to the question whether to go single or multi TF is more difficult to find for the Japanese than for the USN,
as the IJN is always short on suitable CV escorts, at least in numbers required.
The advantages of using a low number of CV TFs are much greater than for the Allies, I will try to pay attention to this.
