Dec 30th:
CV Lexington is confirmed lost; I was so worried about it running away, after all it only got 1 torpedo and 4 bombs, that I decided to split KB into smaller components:
Three carrier TFs; each composed of 2 carrier and a light escort of destroyers. And each moved to a possible retreat path; all have a significant % of their strike capacity (~30%) devoted to search.
Shokaku, Kaga and 4 DDs to SE Woodlark
Zuikaku, Soryu, Abukuma and 2 DDs to SE Rossel island
Akagi, Hiryu and 3 DDs to NE Rennel island
And a SCTF composed of CAs Tone, Chikuma and 2 DDs to move directly to patrol the last enemy position.
I know this was a risk... but considering last turn search was good, and his cruisers were all damaged, I felt it was a calculated risk. Moreover, I made Kaga and Akagi, flagships of two TFs, as they have heavy cruiser guns, while the last TF kept a cruiser Abukuma, in case of surface combat.
Hiei and Kirishima were at Truk, out of ammo, waiting for AKEs. I would had felt safer with them, even without heavy caliber ammo.
In the end everything worked fine, however, I was actually bitching all the turn, because, even though I put a massive search effort that included rebasing Jaluit's patrol boats and Roi Namur's Nells at 100% search, etc. I didn't find the damned carrier!
It was not until the turn ended, that I saw, with relief, that Lexington sank, probably due to some uncontrollable flooding or fire... I think this is the first time I have ever seen a big USN carrier going down with such little effort.

Between yesterday and today all aircraft at Lexington's TF (including cruiser FPs) went down, either in battle, or by ditching or by ship sinking. Even if these were obsolete models, it is really not good for the Allies to lose so many planes (and experienced pilots) so early on the war.
So while the KB didn't sink Lexington this turn... it really mopped the floor with it's escorts:
