Considering you were heavily outnumbered I'd say that the battle was nothing short of a triumph. Does the US have other fleets, or is that really everything?
They've got more, but this will set them back - from what I've seen in the future this basically breaks the back of the USN for at least a year, if not more.
It was only a matter of time for the AI to assemble a mob-fleet, especially with over 1k in IC when he had full rares access. But I had become somewhat complacent with smashing the dribs and drabs he had been sending off to grab ports.
Combined with not really "pinging" those assault fleets with land based air before engaging with the carriers - that is what led to the near total disaster at Kwajalein.
Much like I described in the AAR, I knew the mob-fleet would return at some point and decided that the key was to neutralize their CAG-mob, if possible...it was there that the stacking penalties made them vulnerable, combined with the qualitative advantages my own veteran air had both in skill and (I'm pretty sure at least) in equipment.
I can just imagine those "Phase 1" air battles...because they would be truly epic with a total of around 3000 aircraft deployed...I know the Japanese air losses deployed in that first phase would've been about 1/3 of the strength deployed looking for the screen shots I have of the air fights...less with the fighters deployed. I know also from looking over the screenies that the USN carriers had lost *at least* 20% based on the number of CAGs deployed at the start of Phase 1 to those deployed in combat at the end, add in the strength losses you know the remaining CAGs had and 1/3 losses for them seem reasonable...before they start loosing places to land...so for losses that's about 300 aircraft total for the Japanse vs. 500 aircraft for the USN (once again only a portion of their strength went to air superiority, about 40% I'd guess, the rest were either ground attack or naval strike, depending on situation.)
The "suicide" dash of MBF-1 was figured to be an acceptable risk at that point in the continued attrition battle to further weaken the USN mob-fleet as much as possible before the arrival of CSF 1.
So we can guess in Phase 2 the USN had just over 1000 operational aircraft, but they never deployed more then 700 of those, so they were already carrying around 10 CAG's that were basically combat ineffective. Of course CSF 1 showed up with 330 carrier aircraft...but they were fresh, and added their weight to the approximately same number of various land based aircraft still running missions.
Also important was that CSF 1 arrived just six hours after MBF 1 had disengaged, a decent set of unintentional timing that preserved the life of a number of the MBF 1 minor ships, allowing the re-engagement of MBF 1 into the Phase 2 battle.
Another "lucky" part for the long term was the ability to split off damaged ships...the Shokaku got rocked in the first exchange and I split her off with a damaged escort...later on doing the same to preserve the core of the carrier strength, leaving the least damaged carrier and battleships to administer the coup de grace to what was clearly a broken USN force.
