Ok, I am just going to cycle through the bases (only those of any importance will be mentioned) to see what needs to be done:-
Port Moresby: Fort 1, Port 1, Airfield 3, 1300 troops, supplies to last a month (without combat) and plenty of fuel. AAA weak. The engineers will start improving the fortifications but the port and airfield can stay as they are until we know the base is securely ours.
There's not a great deal of air capability; just 6xCatalinas and some light bombers (12xWirraways), so we'll use these for Naval Search. The Wirraways will cover the approaches to and from Milne Bay at the SE tip of New Guinea while the Catalinas will range much further, covering an arc from Green Island (near Rabaul) through Onton, Tulagi, Gaudalcanal and as far as Fennel Island.
Noumea: Fort 0, Port 3, Airfield 3, only 50 combat troops, supplies will last forever for such a small force. Again we'll try to improve the defences. There are 12xCatalinas here and these will conduct Naval Search of the area Fennel Island to Duff (near Ndeni in the Santa Cruz Islands) with the intention of guarding any approach into the Coral Sea from the East. Unfortunately that will leave a slight gap between their range limit and Guadalcanal.
Lunga (Guadacanal): Nothing there. Totaly defenceless!
Brisbane: Well I'm pleased we have some defences here! Fort 2, Port 5, Airfield 6, 250 troops manning coastal artillery, adequate supplies and its our primary supply source producing oil and resources.
It has US Mitchells and Warhawks which I will continue to train until any threat is perceived. There's 1xSub just offshore but that is sent towards Milne Point to intercept the expected enemy transport route to Port Moresby.
Rockhampton: Fort 2, Port 3, Airfield 3, 300 engineers, adequate supplies and also produces oil and resources. There's Catalinas, Havocs and Mitchells here. The Catalinas are close enough to cover the area to the south of Milne Bay east of the Great Barrier Reef.
Townsville: Fort 1, Port 3, Airfield 3, 90 troops, adequate supplies, and Havocs and Warhawks are based there. Again these will be kept in training.
Milne Bay: Just a small port (no airfield) with smaller supply and fuel dump. No defence force present. But it is at the strategically important SE tip of New Guinea
The above review has concentrated on Air Naval Search so I will mention the basic set-up of the Carrier Air Search also.
Both CV TFs will maintain a close-in CAP, while its escorting Cruiser Float planes will conduct a 360 degree search. Combat focussed Naval Search will be set approximately in the northern quadrant for each carrier as they move northwards.
