IJN 9/30/42
We are evolving into three Geographically based fleets - the need to concentrate the main fleet (and hence constitute KB) having evaporated at least for a time - with the demise of the Allied Carrier Force at Johnston Is.
Not wishing to use our carriers to challenge large concentrations of Allied airpower, until we have to, we will probably use them most effectively in the CENPAC and Aleutians areas. Hence I would expect the bulk of the carriers to be split between those two locations for about the next six months (through end of Q1 43).
Our three forward area fleets then are the Northern, Western and Central Pacific Fleets.
NORTHERN FLEET
Northern Fleet bases include Sapporo(Hokkaiado), Shikka(Sakhalin), with forward bases at Entorofu and Paramushiro in the Kuriles.
Sapporo is a L5 port but will build up to L9. Shikka is L8 building to L9. The 5F HQ has been deployed to Shikka and is 8 hexes from Paramushiro. But distance to Attu and Kiska is 19 and 20 hexes respectively, so to cover these hexes for combat we would have to forward deploy 5F HQ to Paramushiro or thereabouts. This is under consideration although it trades to benefits of 4 port shifts on ship repair/maintenance for the combat multipler of a command HQ.
We had till now been reluctant to build up the installations in the Aleutians, figuring the Allies could possibly take them back quickly with a well timed massive effort. However, we now have the freedom of action to base major fleet units near the Aleutians continuously and hence can support movement of engineers and regular resupply to the Aleutians. Thus building up of the airbases and ports becomes an option. And while the Allies can bring air power to bear here it cannot be on the same scale as in CBI due to lack of numbers of bases.
Kiska now has the 35IMB and the 17A HQ and hence has a credible defence. Forts are L6, L5, L5 respectively at Kiska, Amchitka and Adak with minefields 8000, 9000, 2000, 2000 at Attu, Kiska, Amchitka, Adak.
