Allied Transports

The following classes of xAKs can and should be converted over to xAPs. Many start the game in India area, but I have most converted on their way to USA at Cape Town.

Dominion M (spd 13 with 5550 capacity before conversion, endurance 14,600)
Pacific L (spd 12 with 3900 capacity before conversion, endurance 12,000)
C2 Cargo (available to do so in 2/42, spd 16, endurance 13,500)
C1-A Cargo (available to convert in 2/42, spd 14, endurance 19,300)

I've included some info to help you find these class of ships so you can convert them.

Tarawa

Post by Crackaces »

Ok Alfred .. I was thinking:

6861 Troops 16792 Cargo that I could get the troops off first .. they shock ....

what I reallly really need to be thinking about it 23653 divded into 8 ships Thus 16 ships total for two division. Excellent feedback ..[:)]

I can load one divisioin on AP/AK's and the other on xAP's/xAK's.

On Colombo .. I am not thinking he is thinking of China but this is an excellent point I did not think of doing [;)] I was pushing supply towatd Mandaly and Prome acutally supplying fighter that right now are getting 3:1 atriition on his Oscars and Bombers....

Ok Using all the feedback in this thread and loading up now .. back later ..

Yes, but the unload rate on xAP's/xAK's is only 250 per day. You'll just need a lot of them for the second division.

When I did that atoll sealift calculation, I came to the conclusion that there is sufficient Allied sealift capacity to mount a 2 division invasion. But you really have to concentrate just about all your troop transport ships.

The other thing to remember is that the transport load cost shown on the LCU screen, is for commercial cargo packing. An Amphibious TF automatically loads on a combat readiness basis, and that is 80% of commercial cargo packing.

Accepting at face value that the identified 23653 "combattant" points for a single division is after adjusting for the combat readiness packing, I still don't see how 8 ships are going to disembark the division fully in one day. You are loading each of those 8 ships with 2957 "combattant" points which is still far higher than the daily unload rate of 600. Plus that is not taking into account the tricky exercise of balancing "troop" with "cargo" requirements with the ship capacities.

Now as to your expectation of unloading on day 1 a total of 6861 troop and 16792 cargo, that is only going to roughly equate to a 230 unadjusted Assault Value. Putting aside the disruption issue, and the equally significant disablement/drowning casualties resulting from any enemy CD gunfire, you really are relying on the Tarawa garrison being much weaker than the ball park figure previously given of about 160 unadjusted Assault Value.

The more I think about it, the more convinced I am you would benefit from looking up Speedy's AAR. The last entry in there was made about 3 weeks ago.

Yes excellent advice .. I converted mine at Columbo and then sent them to the United States. They have been running forces between SF and PH, and PH to various points from Tabatuea to Noumea (all require Amphib initally because of a lack of level 3 ports to start ) ... but now these platforms are going to be missioned to drop stuff upon the shores of Tarawa and subsequently depending on how well this goes Ocean Island.

One thing I like about the Pacific L class is that they do not waste space since I am not loading more than 800 troops/Cargo on each one anyway for an offensive mission.. it is such a waste to load 800 on a Presdient class AP for example. That is why they have been working extra hard on moving stuff from friendly to friendly port using the President Monroe class and I did not even consider them for an amphib mission unitl the 3/43 upgrade to APA.

But this is great advice for the newbie like me ..

Also consider that two divisions will be seriously overstacking the Atoll. As such there supply consumption will be enormous. There is a very good chance you will find your self with two highly disrupted Inf Div with no supplies after day two. I really think this is a "Bridge Too Far" scenario in the making

Which is precisely why the operation must be structured to capture Tarawa on day 1. Then the the two divisions can immediately be lifted off Tarawa. If the operation can't be so structured, then vettim89's comment will be a most suitable epitah.

Ultimately, by far the best defence of any size 1 island (albeit Taraw is a size 2) is to sink the enemy fleet before it arrives.

Tarawa is a small atoll with a stacking limit of 30,000 so that part of the mission will not be the issue. [We had this debate on the War Room posting] However, you make an interesting point and this is a very interesting problem. I took Alfred's advice to serious considerationI really never looked at the big cargo number but the troops number thinking if I can get troops on shore they can shock. But ... one really needs to divide 23K by 600. That is 40 ships! I can't load 40 ships on the dock! [X(]

The other part of this equation is the 160 AV. The solution might be to reduce Tarawa using Dive Bombers and bombardment [Nemo is on the CENPAC Staff [:D] ] . I have 30K supply on AKE's at Tabateua that will support 15 bombardment missions. That is one turn there, one turn to rearm and one turn hit and back. My previous experience with bombardment with just the Mississpii, I took out 500 troops destroyed and 10% disrupton. I can put 7 BB's on target each mission. Combined with Dive Bombing by 130 Dauntless DB's I am thinking we can reduce Tarawa by 50%? This will make the slower unloading over say 4 days still feasible. Then the question becomes .. is this enough to make the Amphib mission stick?

So .. next turn the Big E and Yorktown begin to rain hell on earth, with a 7 BB Bomabrdment TF 3 turns later, and I have a recon air unit on Tabetuea to check the results. In the meantime I will load up the Amphib TF's. That will take 4 days at least. During these 4 days I will check on progress and decide the mission.

Tarawa

Post by Crackaces »

Ok the rules say "Regular Transport Ships. (Commissioned Naval AP/AK) in Amphibious
TFs, unload at a Rate of 600 points per ship per turn." Somehow I was thinking per phase .. that means given 15 AP's & 2AK's -- 5100 Cargo points per phase. I think I get the full turn to unload before my opponet can decide to try and push me into the sea. That means 10,200 cargo points on the beach before he reacts. We have 23K cargo points to complete the landing in 2 days for 384 AV minus causualties and disrupton from the landing.

Alfred's right .. Its going to have to be one division on the beach and the CVTF and SAG will have to reduce Tarawa to AV 100 before the invasion starts. I am going to assume a linear regression line and if 4.8K = 160 measn each AV = 30 men 100 AV = 3000 men.

Let see what 130 DB's and 7 BB's can do to make that number happen. In the meantime we load up the 24th division onto 15 AP's and 2 AK's.

Godspeed . I hope this is not worse than the real Tarawa ...[8|]

Sometime this week I will update the thread s to the affects of DB and BB's ...

RE: Tarawa

Post by Crackaces »

I reloaded ther 24th Division on 18AP's and 2AK's this turn after completly unloading. I can do this if I completly undock everything and only have these ships docked. The smaller the AP the better since it does not take up tonnage space and we are trying to spead the wealth so to speak.

CR had the most interesting posting on GreyJoy's thread. In particular, we defined just what it takes to accomplish the strategy of a Late 1944 early 1945 invasion of Formosa -- 10 Divisions and a lot of support in terms of CV/CVE's.

Still I think this is the goal rather than the DEI as first thought. No Malaria to contend with on that route ...[;)]

We are still workign on invading Tarawa .. it will take another 10 days to get stuff set up ...3 CV's arrive into theater in 24 days. The Saratoga @ PH. The LadyLex from Seattle, and the Hornet from Balboa. With 5 carriers in theater it is time to think about pushing a little harder.

RE: Tarawa

Post by Crackaces »

We hit Tarawa again .. this time with 2 ol' BB and some friends. One thing .. a lot more varation in this attack. The first attack killed about 100 men and disabled 4 Non-combat squads .. this attack is reported to have only killed 13 men:

The first attack of 25 FEB 1942:

Night Naval bombardment of Tarawa at 136,128

Allied Ships
BB Mississippi
CL Trenton
CL Detroit

Japanese ground losses:
116 casualties reported
Squads: 0 destroyed, 8 disabled
Non Combat: 0 destroyed, 7 disabled
Engineers: 0 destroyed, 1 disabled



Runway hits 3
Port hits 2

BB Mississippi firing at 53rd Naval Guard Unit
CL Trenton firing at Tarawa
CL Detroit firing at 53rd Naval Guard Unit


Now a follow up attack on 17 MAR 1942:

Night Naval bombardment of Tarawa at 136,128

Allied Ships
BB Mississippi
BB Idaho
CA Chicago
CL Trenton
CL Detroit

Japanese ground losses:
13 casualties reported
Squads: 0 destroyed, 1 disabled
Non Combat: 0 destroyed, 1 disabled
Engineers: 0 destroyed, 0 disabled



Runway hits 1
Port hits 1

BB Mississippi firing at Tarawa
BB Idaho firing at 53rd Naval Guard Unit
CA Chicago firing at 53rd Naval Guard Unit
CL Trenton firing at Tarawa
CL Detroit firing at Tarawa



The most significant piece of information is the 53rd Naval Guard Unit. If this is the only unit present -- he has simply left the orginal invasion force on the island. I beleive this starts out around 58 AV.

The other significant part of this raid is that the results can vary extermly .. I cannot count on a set amount of missions yielding some set amount of damage. Even within some reason. This is going to take more effort than a couple of raids. Disbaled squads heal too qucikly for my liking and only count on invasion day. I think I will remain quiet next turn.

I sure hope my BB's are more effective supporting an Amphib TF .. this will be the critical time.

We are now D-DAY-10 ...a little delay unloading and reloading the 24th Dvision..

Also .. quite a few more submarines have shown up at PH ...[8|] I have contacts on 5 ...These will have to be reckoned with on the way out of port ..

Post by Crackaces »

My Amphib operation took its first baby steps toward Tarawa. I have to skirt the coasts of the Islands and then breakout south of Hilo. PH is cramed with IJN submarines. The Baker Island Area is also a death trap of sorts and will need to be negotiated.

Funny little action today off Noumea:

ASW attack near Noumea at 114,160

Japanese Ships
SS I-17

Allied Ships
DD Vampire
DD Kortenaer
DD Witte de With



SS I-17 is sighted by escort
DD Kortenaer fails to find sub and abandons search
DD Witte de With fails to find sub, continues to search...
DD Witte de With fails to find sub, continues to search...
DD Witte de With fails to find sub, continues to search...
DD Witte de With fails to find sub, continues to search...
DD Witte de With fails to find sub, continues to search...
Escort abandons search for sub

..
But he gets a crack at the real force:

Sub attack near Noumea at 114,160

Japanese Ships
SS I-17

Allied Ships
CA Australia
BC Repulse
CA Canberra
CL De Ruyter
DD Selfridge
DD Scout
DD Voyager



SS I-17 launches 6 torpedoes at CA Australia
DD Scout attacking submerged sub ....
SS I-17 eludes DD Scout by diving deep
....


Good news .. My forces are reacting first for once ..

Now for some bad news ....[:(]

Submarine attack near Port Moresby at 97,131

Japanese Ships
SS I-15

Allied Ships
AVP Arend, Torpedo hits 1, heavy damage



AVP Arend is sighted by SS I-15
SS I-15 launches 2 torpedoes at AVP Arend


I have 6 more APD's coming to do a fast transport from Oz to PM. About 4 days away. PM is in deep trouble and needs supplies.

More later ..

Do you control the skies over PM?  I know your having issues with your ASW forces being on break whenever a sub is around.  Something I did againist my opponent in our Canal game.  I send some small AKs to PM with auto disband on.  Then pull one out dock and unload. Disband that one pick the next AK and so on.

Excellent Suggestion! Right now he has a sub right there in the only hex I can get into port and this guy is hell .. and no I do not control the skies .. yet .. but .. this will be the most interesting turn so far ...

The IJN has decided to raid Baker Island. The KB cannot possibly yet be within range as they just raided Colombo. Thus the picture below .. no additional intellgence besides the fact that a mini 2 CVL CVTF with escorts (18 ships total? including 3 CA's and 4 CL's?) decided to show up and raid Baker Island.

I have the BigE and Yorktown south of Tabetuea they are headed full speed to the spot on the end of the arrow . I have 25 PA's from Baker Island and Tabetuea covering all possiblites of his movement at cruise and full speed. With Luck its 2 CV's vs. 2 CVL's at 200 miles .. with fate I miss him ...Its clear skies expected and he is raiding Baker Island. I can not think of a more perfect situation ....I will post how this goes ...

Beware Tarawa. The CVTF could be a lure into Netty land. fingers crosssed.
As a follow up, If Crack has an aggressive TF leader on say a 5 or 6 react could he be inadvertantly lured into a Netty trap?

Do you remember that scene from Midway where the damaged aircraft were crashing on the decks but everybody was jublant ...

First, we did not meet exactly where we thought and in fact he went southwest rather than southeast as I was tracking .. so first thing in the morning both TF's find each other and exchange pleasentries.. [I sure wish I could write like Cuttlefish or the little ship that could [:(] One problem .. the BIG E cancelled their attack and did not fly ??????

Shoho 1 Hit critical she is on fire
Ryujo, 6, hits she is on fire
Zuiho, 2 Hits and operational?


USN: The BIG E ...She has her full complement including fighters! The Yorktown did all of this this alone! Now will he leave the carriers behind [got to be 1/2 speed at least?] and keep his CA's with them to defend? That is the question?
