I do hope an attack on Truk is possible, the concentration of ships in a limited area sounds very tempting. Probably heavy losses on the attackers, but still carriers and capital ships compared to planes seems like a gamble worth taking.
That would be suicide. The Pacific Fleet has one fully operational carrier, one damaged carrier that can be repaired locally and kept operating but will need a yard period eventually, and Guadalcanal is still heavily contested. Truk also still has plenty of air defenses and is one of few Japanese bases with radar coverage.
You're not going to see Truk bombed until Nimitz can grind down the Japanese more, and not until he can throw at least five or six fleet carriers plus escorts at the base.
Keep in mind the premise of this timeline. It's not so much the Allies having more then OTL, it's a case of a couple commanders on the British side managing to outsmart, outthink, and outfight the Japanese, and successfully removing a number of key Japanese assets from the playing field while managing to avoid serious losses of their own forces. The fact that the fate of some Allied units has changed(sometimes for better, sometimes not) is more a butterfly effect then anything.
Don't make the mistake of looking at things with 20/20 hindsight. We the readers know the Japanese are loosing faster ITTL then OTL. From the in universe perspective of the 1942 military leaders, they've achieved great successes, but they've also taken quite significant losses. This most recent naval engagement saw the damage or loss of numerous vessels, including the loss of USS Wasp, USS Enterprise and other ships have suffered damage extensive enough to force them to return to Pearl Harbor or the west coast for repairs, Rear Admiral Daniel Callaghan has been killed in action, and a lot of aircraft have been shot down or damaged to the point of being written off and pushed over the side of the carriers, if if they managed to get to Henderson Field, likely being stripped for parts.
Speaking of the late RADM Callaghan, I noticed in one of the updates, correct me if I'm wrong, but Rear Admiral Norman Scott is still alive ITTL. It's believed that OTL his death may well have been at least partially due to friendly fire after his flagship, USS Atlanta, was hit by gunfire from Callaghan's own flagship, the heavy cruiser USS San Francisco. Here, while there is the likely possibility of more surface engagements around Guadalcanal and throughout the Solomons in general, that friendly fire incident obviously isn't going to happen. Scott was viewed by many as a quite capable flag officer, and in hindsight, it has been debated that if he had been placed in overall command during the Naval Battle of Guadalcanal, instead of 2nd in command under Callaghan, that many of the costly mistakes and losses of that battle might have been avoided or at least mitigated somewhat.
Here, I doubt we're looking at another 4 or 5 star officer in the making, but if the butterfly effect has seen to Scott getting a new lease on life ITTL, he could go on to be a quite accomplished surface warfare officer, maybe even make Vice Admiral at some point.
