RE: RA 5.4

Post by FatR »

ORIGINAL: John 3rd

Remember FatR that we ADD two cruiser/cv-sized slipways to Japan with RA. Did you factor that? We have one at Shanghai and added the other somewhere in the Home Islands. WE had one heck of a discussion as to whether there was room in any of the HI Ports and came up with only the one. Cannot remember WHERE for the life of me!

Well, that's why I asked the list of additions so far... I do think that two extra slipways may be excessive, though, seeing as everything can be built by concentrating on existing ones and intensifying construction works there, see the latest table above. Resources aren't infinite, and if extras are there, they are needed for more urgent things assumed by the mod, such as mass production of 100/65 mounts and AAMGs. One extra slipway, however, in combination with probably expanding the slipway at Sasebo, will allow to build new CLs in timely manner, and further unload the Mitshubihi shipyard in Nagasaki for conversions, allowing to convert all suitable APs before 1944. With two extra large slipways, we'll need to add extra ships or have them underloaded, and I think we already added enough extra ships. What do you think of that?


EDIT: Alternatively, both the smaller shipyards at Sasebo and Yokohama can be expanded to handle normal cruisers (or carriers).

Hi folks, after upgrading to RA 5.5 i still have the problem of 9999 days upgrade.
The game asked for adding database changes, of course i answered yes, and than showed something like "database updated succesfully" but my Air HQ are in the same situation as before [:(]
I feel like I'm missing something? [&:]

Everything shows correctly when I launch 5.5. Maybe a bug due to imperfect update? Does anyone else still see this problem?

It's surely my fault cause if I start a new game I see the problem solved: the Air HQ upgrades in 555 days instead of 9999!
but in my current game I've an unsuccesfull update (I've tried it three times and it always says apdate succesfull)
In the preferences screen the scenario, after updating, still shows RA 4.1 instead of RA 5.5 [&:] but in the same time it shows also "database updated this turn". It's something like I'm missing a file or I'm putting it in wrong location?

Files should be in the scenario folder. As far as I can see, all 11 scenario subfiles are included in the download. The most likely reason lies in the database changes between 4.1 and 5.5, which can cause all sorts of unpredictable bugs. Don't think there is a cure - I'm personally still stuck with the 1.something version of Scen 70 in my longest-running PBEM game, because attempts to upgrade caused fatal bugs since long ago.

That said, addition of some radars and flak to air flotillas is not something Japan can't live without. The above-mentioned game got stuck with full-strength Chinese units and a couple of less significant problems...

RE: RA 5.4

A slightly modified shipyard load program, assuming upgrade of two smaller shipyards to shipyards capable of handling full-sized cruisers/carriers. Reduction of load on Mitshubishi's shipyard at Nagasaki might allow to convert all potential CVEs before 1944.

Note that there's a theoretical possibility of laying two more cruisers or Unryu-class carriers for late 1944, but considering material shortages and needs of late-war games, I'd prefer to stick with expanded destroyer construction.

Speaking of destroyer construction, before the war IRL it was primarily handled at the Maizuru arsenal which built only destroyers, the Fujinagata shipyard at Osaka and the Uraga shipyard at Tokyo, with Yokosuka and Sasebo arsenals, and the Kawasaki shipyard from the table above also participating to a lesser extent. During the war, both Mitshubishi shipyards also started to help with destroyer construction. I just don't see how this can be centralised to just two shipyards, or how such centralisation can benefit Japan, particularly late in the war, when almost all shipyards built some destroyers. Expanding the Maizuru arsenal and making it reponsible for training teams of engineers to help other shipyards with streamlining construction of standardized destroyer designs (in RA Japan builds only Akizukis and Matsus - improved Matsus, if you accept my earlier proposal, John - during the war, instead of also Yugumos and Shimakaze).

RE: RA 5.4

Nagasaki 4 certainly appears to be open for two ships. Available 5-1939...

Sasebo KK (10/42) and Yokohama #1 (3/43) could each take one ship each.

Possibilities:
CL Agano is not listed so she goes into Nagasaki #4 'C' Slot 6/39 - 11/41
Two CVLs (Ibuki and Kurama). Place Ibuki at Nagasaki #4 with dates being 12/41 - 6/43 and Kurama in the 'D' Slot of Kobe #2 with dates being 6/39 - 1/42
Two CVE conversions we added (Saiyen and Kuzuryu). These were two Shadow Program ships never converted. Each could go into the 'D' Slots for Sasebo and Yokohama with dates being Saiyen 11/42 - 11/43 and Kuzuryu 4/43 - 4/44.

Don't know if that works but it is a proposal. That chart is like playing tetras!

RE: RA 5.4

Post by FatR »

Purely theoretically expanded shipyards can handle all this, but where materials will come from? Also, why build dedicated CVLs before the war even begins?

I still stand with the idea of returning to the old RA construction lineup (only 4 new-project CLs, no extra CVLs), but add CVE conversion options to all 5 suitable xAPs, listed upthread (useful, and takes no build points, but is not too useful, because these ships won't have organic airgroups), and shift dates as the table suggest, so Unryu-class carriers will be available earlier and some of the new ships later. Late in the war Japan needs destroyers and small, fast transports above all (besides aircraft, of course), in my experience from 1944... If you really want to add 2 more CVLs, Japanese can start to construct 2 additional light cruisers before 1943 in Sasebo and Nagasaki, and then convert them to CVLs on the slipways, with availability in 1945. I see no point in adding surface combatants with availability in late 1944 or 1945.

Also, I thought of another idea, related to my light forces proposal: although Japan doesn't produce 127/40 Type 89 twins during the war anymore, quite a few mounts of this type will be available after being removed from newer carriers and cruisers, as well as battleships. As Matsu-class destroyers are supposed to be bigger in my proposal, and carry 2x2 HA guns mounts, it makes sense to arm the first series entirely with these now-available older guns. The later Tachibana class will switch to twin 100/65 mounts, after their production will allow for that, and the stores of old guns will be exhausted. This will reduce Matsus' capabilities, but beggars can't be choosers.

RE: RA 5.4

Post by John 3rd »

I have held off truly jumping into this discussion due to life being incredibly busy, however, have some time today so I will revisit some of what was written earlier as well as where we are right now.

Thoughts on Ship Construction:
1. Your comments on building dedicated CVLs just when the war starts are totally on target. Why would the Japanese build them? They would not. These would have been conversions like what you describe from the enlarged Agano-Class. It would then make sense as to why there are fewer CLs within the Building Plan. Since the CVLs would be of marginal use then it makes sense to me in NOT building them.

2. So what would be built when war begins? Throw out two CVLs and add a 4th Shokaku-Kai would be my response. The Japanese nearly always built pairs anyway. They lay down a pair of Sho's (Shokaku--Zuikaku) in 1937, then a 2nd pair in 1939 (Taikaku--Ryukaku), and a final pair in 1941 (Renkaku--???). Through acceleration the Japanese could get a pair of CVs in early-43 and another pair in early-44. They would then be DONE with heavy warship construction from the pre-war. Remember no Taiho and no Shinano. There would certainly be steel enough available by not building these RL ships as well as others...

3. With no Training Cruisers built there is TIME to build an expanded class of CL. The argument is whether they are BIG CLs or DL? The Improved CLs seem to be what you really want to go after so either:

a. Build the bigger CL that is much more akin to the original Mogami-Class and make them BAD-ASSED ships. Build just a small number of them but they would ROCK!

b. Scale back to a true Destroyer Leader that would be cheap and easy to build. They replace the old WWI CLs as originally intended but are modern ships. Heck: Go with 4 twin mounts and a full DD's TT complement and build 8-10 of them. They would be larger then the Moon-Class DDs and be a fast DL. There would be several already in commission when the war starts and then allow for 4-6 reflecting completion of the Class before realizations ets in as to just how out-matched the Japanese are.

RE: RA 5.4

Post by John 3rd »

Essentially I propose we go with either 8 of Proposal 1 OR 4 of Proposal 3.
ORIGINAL: FatR

As about cruisers, my thoughts continue to go in endless circles, John. I cannot choose among the following:

(1)The RL Agano

Pros: Can be built cheaply and rapidly, using second-rate shipyards, therefore can be built in relatively large numbers. I find myself using old 5500-ton CLs very actively in my games, because they are numerous and expendable, RL Agano can be same but better, and with pre-planning probably at least 8 can be constructed.

Cons: IRL it was too vulnerable and likely to sink or completely lose power from one torpedo hit against machinery spaces, which is not desirable for a fairly large ship. And not that cheap in the end - almost half the cost of an Unryu-class carrier. In the game qualitative inferiority within your class is punished harshly.


(2)A Super-Agano

An example, is, again:

Image

Pros: Actually can take on Allied cruisers, at least in the night, while possibly still being relatively cheap and suited for mass construction.

Cons: Cheapness and suitability for mass construction on second-rate shipyards are not guaranteed. Is almost as vulnerable as RL Agano, but even bigger and more painful to lose.


(3)An Oyodo-sized cruiser

By the current point "Aganos" in RA actually approach this. I prefer this project, already posted in the previous thread, however:
Image

Pros: More reasonable protection, can hold its own against American CLs at least in night combat, a better TF escort, due to powerful AA armament. The best balance of qualities required from a cruiser.

Cons: It's unclear if shipyards that built Aganos and training CLs can handle this. The first four can be armed with turrets taken from Mogamis, cutting down on the expenses, but after that they won't be cheap. Still weaker than Washington cruisers.

(4)The standard Japanese Washington CA

Note, that Ibuki and Hull #301 were based on Suzuya, not Tone, IRL.

Pros: More powerful and useful than any other cruiser, maybe not IRL, but certainly in the game. Good survivability and relatively little chance of being taken out with a single lucky shot. A pure artillery cruiser, a Tone-type scout and a Tone-based cruisers with increased medium AA armament all are very useful

Cons: Very big expensive, due to being an erzatz battleship, like all Washington heavy cruisers, but particularly Japanese ones. Why not just build battleships, after you are no longer bound by treaties? Japanese IRL certainly thought so, and laid down new CAs as a part of the Circle Urgent RL program only because they needed ships right now and hoped to complete those hulls quickly.


I think that the initial RA plan of building four of #3 and two of #4 is pretty nice and not particularly outlandish (considering, again, availability of turrets from Mogamis, absence of training cruisers, etc, etc), but I don't the idea of just adding more cruisers very much. Unless they arrive in 1945, making them more like "build at your own risk" projects, rathet than something Japan is expected to have.


Note that for Perfect War I now want to pick one of these options and build only that, to maximize production efficiency, but just cannot make a choice...

Any more additions to the Allied side in 44 - 45? They could use some extra 2nd/3rd generation aircraft production.

John,

The fourth Shokaku-kai, and the Oyodo-sized cruisers would get my vote. Some additional standardization, plus a lot of usefulness. Not sure how much of a difference they will make, but I like the idea :)

RE: RA 5.4

Post by FatR »

I'm not sure we should be remodding all over again things that already have been changed. Crazier ideas should wait until we return to the Perfect War. But the cat is out of the bag with 5.0, as it seems, and Babesfying RA is at least a good pretext for the new changes... By the way, John, do you agree with that idea?


Regarding your ideas:

(1)The fourth Shokaku-kai carrier. Avoiding breaking the traditional Jap patter of carrier pairs makes sense, but just spawning a fourth carrier doesn't. Replacing 6 Unryus with 4 Shokaku-kais could potentially produce sizeable savings in materials (and shipyard space), particularly considering the standardization bonus, but is currently problematic in game terms: construction 2 100 Durability ships is much more expensive than 2 63 durability ships. In the light of that I note, that there's no need to raise Shokaku-kai's Durability. It can remain at 90, with an airgroup of 75 planes (the maximul practical complement of the Shokaku class with late-war planes IRL). This will keep the construction cost a bit more reasonable. The first pair of Shokaku-kais, as you said, arrives early 43, the second early 44, the last two late 44 to very early 45. 8 modified Sho-kai = 600 aicraft. 6 Unryus + Taiho + Shinano + Ibuki = 524 aircraft. The result = more aicraft than IRL, and their platforms arrive fairly through 43-44, instead of mostly being concentrated in late 44-45. Currently RA 5.5 provides 3 Shokaku-kai + 6 Unryus + 2 greatly enlarged Ibukis = 717 aircraft, albeit most of them on weaker and more fragile platforms. A bit too many, I think! We wanted to avoid miracles.

The build point comparison, if you want to know, is 648 000 NSY points to fully build up an all-Shokaku-kai program, and 576 860 for the current program. The former will become cheaper if Shokaku-kai durability is reduced below 85. However, I'm not counting here 3 CVEs (Kaio, Sayien, Kuzuryu) that I propose to remove from the queue and replace with on-map conversions of 5 large APs. These CVLs cost 30 990 NSY points. So 8 neo-Shokaku-kais will break about even with the current state at durability 87.


Note, that the game and IRL are, IMO, in contradiction here, smaller ships are far too cheap to build. In practice Taiho's cost was only 30% higher than that of Unryu and Japs chose the latter for wartime production because they needed to restart carrier construction real quick after Midway, with no hulls on slipways at that moment, except Taiho, and smaller hulls, powered by standard cruiser engines, were faster to construct with little preparation. Note, however, that they failed to build enough proper engines for all 6 Unryus.


(2)On cruisers. Remember, that we picked to build 4 CLs with 3x3 155mm turrets to utilize guns taken from Mogamis. This was the whole reason beyond the current CL project. I just propose to place these turrets on Oyodo hulls in Proposal 3. And I do think that I personally prefer building 4 of Proposal 3.

IIRC, a few aircraft that stopped production in 1945 continue until the end of the scenario, and Hellcats are tougher. Ask John if anything was added to their fleets...

RE: RA 5.4

Like the sound and logical thinking Posted in the above comments FatR. Does anyone have thoughts regarding this?

Allied additions in RA (currently) include:
1. UP to 10 additional CVE conversions that are available starting January 1, 1942.
2. A pair of additional CVLs coming in early-43.
3. Immediate conversion of the old WWI Omaha-Class to CLAA.

Are there any serious and realistic ideas for changes to the Allied OOB? Might as well voice them since we're looking at an RA 6.0...

RA 6.0

Post by John 3rd »

Changes/Additions as I see it:

1. We completely scrap the Japanese Emergency CV Program and go with all Sho-Kais as described. Expensive compared to the Unryu's but FAAR better ships.

2. Go with a Revised 4th Circle of: the first pair of Sho-Kais, two BCs, two Tone-Kai, four Oyodo-Style CLs: 3x3 Main Armament, 5x2 100MM AA, 4x2 TT, and then its seaplane complement.

3. Wartime Construction:
a. 4 Sho-Kai's built in pairs
b. 5 Additional Conversions WITHOUT organic air groups

Did I screw any of this up?

Well, technically it is 8 Shokaku-kai carriers instead of 6 Unryus, Taiho and part of Shinano, and with no significant pause in carrier construction after leaving the treaties.

Oyodo-replacements are supposed to carry 6x2 100/65 (with less AAMGs, though, as the place used for them on RL Oyodo will be taken). And 4 Shokaku-kai carriers must be laid down before the war, the second pair probably as a part of Circle Urgent - 3 ships that are already present in RA + another one. But the general idea is as you described.
