Aug 27 - Sept 2, 1942
Death of the Copahee - Congressional Investigation - Tanna Falls
The IJN will break the convoy lines between the West Coast and PH. PH is in no danger of running out of supply (a million or so) but fuel is down to a 3 month supply. CINCPAC will need to deeply consider how to handle this threat. It will be argued (at the investigation) that the loss of the Pennsylvania and Copahee are due to faulty analysis of the available intelligence.
KB: The locations of the KB and mKB are unknown.
US CVs: Docked at Pago Pago.
AIR WAR:
SURFACE WAR: We catch another raider between Australia and New Zealand.

On 8/28 Japanese raiders in the NorPac kill another not-picket. At this rate - losing 5 in last 3 days - the allies will run out of xAKL before the end of '43. Another plan will be needed.

AUSTRALIA: The Japanese take Lord Howe Is on 9/2. Along with Norfork Is and Raoul Is it looks like they are trying to break the PH-Aus convoy lines.
PH and points east: To try and catch the pesky Japanese raiders sitting on the convoy lines between SF and PH the newly commissioned CVE Copahee, embarking 2 sections of fighter and one of dive bombers is sent on her maiden voyage. The 1st swing south from SF spots a submarine and the SBDs are put on ASW patrol. Then the CVE and her 4 DD escorts run into a heavy SCTF in broad daylight. Later that day Japanese aircraft appear over the already doomed TF (note the 20 Vals - is this more than 1 CVE/CVL?). The Copahee will never launch a single aircraft in anger. The level of incompetence of the West Coast USN commander leads to a Congressional Investigation.
