MARIANAS SCENARIO v1 NOW PLAYABLE

[Andy Mac]

OK Guys not doing this with my dev hat on

So this is just me but I have been building a marianas limited map scenario

So far I have a map and a first draft of the Jap Land and Allied ORBAT

I have a first draft of the Japanese naval ORBAT and a reasonable cut of the USN combat ships

This is waaaaaay waaaaay out of my knowledge base so any comments welcome. In fact if anyone has time to check everything int here so far would be appreciated.

Still need to do the air side (which I may be gettingsoem help with) and I need to try and build the transports for the USN which I have zero idea how I am going to do. So if anyone has a list of which AKA#s APA's LST's etc served in this campaign would be really welcome.

AI I havent even started to think about yet.

So it doesnt work as yet and it probably won't be a real version 1 until post Christmas but I thought I would share where I am up to so far and see if anyone can help

Save is this thread

[Andy Mac]

I need things like a source for the LST's used any APA's AGC's AK's etc LCI (R's) etc etc any help much appreciated

[Andy Mac]

OK so I missed the old BB's adding them in now and the 3 CVE's

I have a list of LCI's and LST's from the original Marians scen not sure how right they are

[JeffroK]

Andy, have you looked at the US Army, Navy & UISMC histories at Hyperwar.
I know the Army History went into a lot of detail for Okinawa, I cant remember the detail on the Marianas.

[Andy Mac]

yes I picked them clean but they are a bit lacking on who garrisoned the bases I have the main assault forces but its the follow on forces and the marshalls guard force that I am lacking

In AE the difficulty is not the main combatants its all the little aux's that take the time

[Andy Mac]

I just recieved a major update of USN ships from Terminus so looks grand !!!!

[JeffroK]

really right field, (assuming you are looking for US info?)

There is a site that list combat credits given to units, as the Marianas were not cleared immediatly maybe some of these units got combat credit for garrison duty.

[Andy Mac]

Yes ists US stuff my library is not great for US data

[Andy Mac]

OK I now have the main Amphibs and command ships in need to start looking for Aux Ships now

[Dabo]

Andy,
here you can find a detailed OOB for the Northern Attack Force (TF52) http://www.ibiblio.org/hyperwar/USN/ACTC/actc-21.html (from page 878). I've got an OOB for the Southern Attack Force (TF53) but not as detailed (no names for most of the amphips and aux).
IICR in Morison’s History of United States Naval Operations in World War II Vol. 8 there’s a pretty detailed OOB unfortunately I can’t seem to find the book.

[Andy Mac]

Great thanks I have used hyperwar quite a lot.

Its startingto come together I have a decent enough attempt at a 1st stab in reality although to be correct i should have the right defence units in the Marshalls actually it probably doesnt matter as lets face it the Japanese dont have any ships to launch an attack with so as long as I stick a seabee and av unit on each one they dont really have to be the right av support and seabee unit.

I need to add some PT boats and a couple more destroyers as I only have the fleet destroyers in at present.

After that I will have enough land and sea for a working 1st draft

Then its onto Air then finally Ai

[Nikel]

I do not know if this is what you are looking for, but here there are lists of transports, LSTs,... from the page 878

Andy, I assume you have read Campaign in the Marianas

(I believe these could also cover the landings at Angaur)

[Sardaukar]

I will definitely be playing this one!

Good one for beginners too, because it introduces the complex amphibious ops to be learned as Allies.

[Andy Mac]

Needs a a little work to get it close probably about another 50 allied ships to add (mostly DD's and replenishment stuff)
 
But say about another week and it will be playable PBEM

[Andy Mac]

I probably need to dig out a rough OOB for the land based air - one of my colleauges is goign to do it properly but until that is finished I would probably like to rough one in to allow some testing anyone know the OOB of the Japanese or Allies in the Marshalls/marianas in the Air at this time.
 
Doesnt need to be exact just an approximation as I think its being done properly elsewhere

[Andy Mac]

p.s. I will update the save with the latest version tonight

OK really rough air OOB to get a working prototype will be

Allied

With this lot and the last few DD's I will get something with all the bits in but still needing to be checked and playtested then when I get the proper air OOB I can overwrite what we have above
