JNAF Proposed Revisions and Queries

[el cid again]

This is a redo for eratta, to work the Ise/Hyuga issue now I understand code better, and to divide 7 recon units into two parts - since 24 plane units are a bit large for WITP play purposes. I also defined slots for future use so where they fit will make sense, and some units for ships not yet in play.

Let me give compliments to whoever did the original JNAF OB. The start of war OB is quite good for unit identification and aircraft assignment (with the notable exception of air transports, which are grossly exaggerated, but which are hard to get information about). I have quibbles over unit naming - but the real system is confusing - and ANYTHING you do gets messed up by late war when things get created with a completely different name system. The original OB used a late war carrier air unit name system similar to the real world early war system - and FINALLY it has hit me - use that early war system throughout for carriers. This won't work on land, but it does create the possibility of dealing with name issues late in the war - units can be created with later names using a completely different Table of Organization and machine count - and which are land based and not carrier at all. I am working on this modification. And do not cry too much for the lost transports - since I am adding the Ocean Unit of DNKKK with its H6K2-Ls (and eventually H8K2-Ls) plus the DC Unit with its DC-3s.

Note 71: Shotai split in CHS and stock but combined here. See Note 1. This unit will
reform with E16A1 IF its parent ship converts to a semi-carrier in a campaign game. It should be upgraded to M6A1 (= float D4Y2) to be strictly historical. It will initially have a size of 13 aircraft, and eventually resize to 11 aircraft due to hard code. The correct size would be 14 for Ise and 8 for Hyuga.

Note 74: Data for Tone and Chikuma indicates they flew four two seat aircraft plus two
three seat aircraft. Japanese Cruisers of the Pacific War, Eric Lacroix and Linton Wells II, p. 503.
Note 75: Data for Furutaka and Kako indicate they operated two E7K2. op. cit. Lacroix
and Linton, p. 255. Data for Aoba and Kinugasa is the same on p. 259.
Note 76: Oyodo was modified to operate two E16A1 aircraft, although in the event two
E13A1 were actually carried. op. cit. Lacroix and Linton, p. 628.
Note 77: The Agano class was expected to operate two E16A1 aircraft, although in the
event two E13A1 were actually carried. op. cit. Lacroix and Linton, p. 572.
Note 78: The Oyodo and Agano classes were designed to operate special E15K recon
seaplanes. These aircraft were unsuccessful and were never operated by ships.
Note 79: Four old light cruisers operated rare night reconnaissance seaplanes during the
early war period. Since these aircraft are not available, E13A1s are used instead.
Note 80: Tsugaru is wrongly listed as having a seaplane by CHS. Okinoshima is
wrongly listed as not having a seaplane. For this reason Okinoshima is substituted for Tsugaru. See Note 1.

Note 98: Organization unknown: assumed to duplicate 19th Kokutai. Date of formation
unknown: it is not listed when the war began but it is listed by July 1942. op. cit. Okumiya & Horikoshi, Pp. 30-5, 118.
Note 99: The Daitai of this unit has four Chutai or 48 aircraft. Each Chutai has four
Shotai or 12 aircraft. Each Shotai has three aircraft. op. cit. Hata & Izawa, p. xiv.
Unit TO&E from Hata and Izawa, Pp. 216-218.
Note 100: This unit is known to have operated night fighters but not day fighters. It is
assumed to have two Chutai of night fighters (similar to F2 Daitai/131 Kokutai) and two Chutai of recon aircraft (similar to R1 Daitai/153 Kokutai), all operating variations of the J1N1. op. cit. Hata and Izawa, p. 362.
Note 101: This unit became Reconnaissance Hikotai 102. op. cit. Hata and Izawa,
Pp. 193-195.*
Note 102: This unit was Fighter Hikotai 311. It transferred to 301 Kokutai on 10 July
1944 and 201 Kokutai in Aug 1944. cit. Hata and Izawa, Pp. 193-195 & 111.
This unit was represented by lines 401 and 402 in CHS.
Note 103: This unit was Fighter Hikotai 901. op. cit. Hata and Izawa, Pp. 193-195.
Note 104: This unit was Fighter Hikotai 301. op. cit. Hata and Izawa, p. 110. It had
been assigned to Kokutai 202. The 202nd was a renamed 3rd, and is not otherwise
listed. Hikotai 301 is listed from the date of a reorganization/reinforcement which defined it. op. cit. Hata and Izawa, Pp. 129-131. CHS listed this unit as forming only in November, 1943.
Note 105: This unit was the recreated Fighter Hikotai 305. Previously it had been
destroyed as a fighting force at Peleliu in the Marianas. The first Fighter Hikotai
305 had been created in the first Kokutai 201, primarily from the already existing
Chitose Air Group. op. cit. Hata and Izawa, Pp. 106-112.
Note 106: This unit was Fighter Hikotai 306 and it was assigned to Kokutai 201 on
4 March 1944. It had been in training. op. cit. Hata and Izawa, p. 110.
Note 107: These units became 303 and 304 Fighter Hikotais on 15 April 1944.
Originally they were the Atsugi Kokutai and assigned training duties for carrier pilots. These units were later assigned to Kokutai 201 and 221, respectively. op. cit. Hata and Izawa, Pp. 209-212.
Note 108: This unit was Fighter Hikotai 812. It was assigned to Kokutai 203 “during the
latter part of October.” op. cit. Hata and Izawa, p. 212.
Note 109: This is Fighter Hikotai 302. It was represented in two parts by lines 431 &
432 in CHS. It is 98% disabled because it has only one pilot! op. cit. Hata and Izawa, Pp. 229-230. It was later assigned to Hikotai 252 (II). p. 116.
Note 110: Each listing duplicates half of Fighter Hikotai 302. See note 109 above.


* From this point in time on, Daitai will be designated Hikotai. Prior to this time, every Kokutai had a single Hikotai which might operate mixed types of aircraft. After this time, most Kokutai had multiple Hikotai, which were specialized in a single type of aircraft. More generally, Kokutai grew in size, and might have up to six Hikotai, each of which often had as many as 48 fighters, or 24 other aircraft.

Page 19

Note 111: This is Fighter Hikotai 315. It was represented in two parts by lines 464 &
465 in CHS. It is 98% disabled because it has only one pilot! op. cit. Hata and Izawa, Pp. 229-230.
Note 112: This is Fighter Hikotai 302. It was represented in two parts by lines 464 &
465 in CHS. It is 99% disabled because it has no pilots! op. cit. Hata and Izawa,
Pp. 229-230.
Note 113: Ready aircraft based (as always) on aircraft actually available on the date the
unit formed. The recon Daitai is 99% disabled because no aircraft were available on that day. This is a mechanism to slow when the unit becomes fully operational. op. cit. Hata and Izawa, Pp. 224-226.
Note 114: Date of formation based on date of aircraft availability data (31 Jan vice 15
Jan 1944). These units became 308 and 312 Fighter Hikotai, respectively. Original TO&E is used. After reorganization these units increased to 48 aircraft each. 221 Hikotai nickname “Arashi” = “storm” op. cit. Hata and Izawa, Pp. 203-206. Both Daitai of this Kokutai were wrongly listed as night fighter units in CHS/stock.
Note 115: Date of formation based on date of reorganization. These Fighter Hikotai
were missing from CHS and stock. 221 Hikotai nickname “Arashi” = “storm”
op. cit. Hata and Izawa, Pp. 203-206.
Note 116: By the time of the formation of this Chutai, the Tainan Kokatai had been
renamed 251 Kokatai. Because units cannot be renamed in this game, the Kokatai name Tainan has been retained. This was the first night fighter unit to be formed using a variation of its recon aircraft. op. cit. Hata and Izawa, Pp. 132-138.
Note 117: This unit was a small Kokatai assigned to defend Hainan Island and Hong
Kong. It had a single Hikotai with two Chutai of 12 aircraft each. op. cit. Hata and Izawa, Pp. 175-177.
Note 118: This unit was a small Kokatai assigned to defend Shanghai. It had a single
Kikotai with two Chutai of 12 carrier fighters and one Chutai of 8 carrier attack
Aircraft. op. cit. Hata and Izawa, Pp. 207-208.
Note 119: 261 Kokutai was nicknamed “Tora” = “tiger”. It was initially authorized
36 aircraft but later increased to 72. For this reason each Daitai is 50%
“damaged” when it appears. op. cit. Hata and Izawa, Pp. 168-179.
Note 120: 263 Kokuai was nickmaned “Hyo” = “panther”. It was initially authorized
36 aircraft but later increased to 72. For this reason each Daitai is 50%
“damaged” when it appears.op. cit. Hata and Izawa, Pp. 178-179.
Note 121: This unit was formed from the 22nd Koku Sentai Yamada Dokoritsu Hiko
Daitai (HQ Squadron). It is not listed again because it is a duplicate unit. It was listed on line 445 as such and on lines 251 and 252 as the fighter elements of the Yamada Detachment. op. cit. Hata and Izawa p. 253.
Note 122: The fighter Daitai of the Genzan Kokutai reformed in April, 1942. On
20 September 1942 the entire Genzan Kokutai was renamed the 252nd Kokutai. op. cit. Hata and Izawa, Pp. 113-116.

Note 123: These are the seaplane bomber units for Ise and Hyuga when converted to
semi-carriers. Both ships also carried a D4Y2 Chutai (which we represent as M6A1 = float D4Y2: see page 3 lines 751 & 752). See Note 1.
Note 71: Shotai split in CHS and stock but combined here. See Note 1. This unit will
reform with E16A1 IF its parent ship converts to a semi-carrier in a campaign game. It will initially have a size of 13 aircraft, and eventually resize to 11 aircraft due to hard code. The correct size would be 14 for Ise and 8 for Hyuga.The Ise-1 and Hyuga-1 observation Shotai may continue to operate, and may upgrade to the E16A1. IF ships that operate the D4Y2 are created, these units should have the number of E16A1 reduced to 14 for Ise and 8 for Hyuga OR these units and the Ise-1 and Hyuga-1 observation Shotai should be disabled (set the date to 460331). Date based on when training completed. op. cit. Hata and Izawa, Pp. 77-79. See also The Hybrid Warship, R. D. Layman and Stephen McLaughlin, Pp. 129-134.
Note 124: These are the historical D4Y2 units for Ise and Hyuga when Converted to
semi-carriers. Both ships also carried an E16A1 Chutai, although they were designed to carry ONLY the D4Y2. Note that these ships can launch but not recover D4Y2 aircraft and will NOT work with the ships presently in WITP. For this reason, these units are assigned the M6A1, a float version of the D4Y2! They are date set NOT to appear in the campaign game, but should be used in 1944 and 1945 scenarios. If used in such a scenario, the date of appearance for these units should be set to 440501, based on when training completed. ALSO the date of appearance of M6A1 should be set to 4405.

Then there is the ugly case: Shinano. She is building - and so is a sister- as a variation of Yamato (with different secondary and tirterary armament) when the war begins. Hull 111 (Kii?) is cancelled. Shinano is ultimately converted to a carrier we CANNOT simulate in this system: she is to carry replacements and to service planes for other carriers. She eventually gets a small air group as well - theoretically - but in fact it never formed. But since we cannot "service" planes for other ships and since the existing ship has ZERO "extra" capacity - there are no replacements. Shinano could actually operate 96 machines and carry 24 in parts - we must ignore spares in this game for code reasons - but we could rate her for her real capacity.

You might have missed it, Sid, but I have already changed how Shinao is represented in CHS for the next update: There are now TWO Shinanos in the ship database - one a BB and one the CV conversion. The Japanese player can determine which one they build (employing a house rule to say that they can't complete BOTH). I have also upped the aircraft capacity, without adding additional air groups.

This is elegant - but you better make the house rule clear. Why don't we do this with some other awkward cases? For example Ibuki? I have tried to build in mechanisms that do not allow a player to have two versions of the same ship (although in the existing game players DO get both Argentina Maru and the carrier she was converted into!).

Andrew, any idea as to how this will be handled by a Japanese AI?

Not that it matters much, the AI needs all the help it can get...

Good question! My guess would be that the AI will try to build both ships. I tried to play with the editor to make one of the ships "halted" at the start, but I could not get it to work.

This change may indeed cause problems for the Japanese AI. But I don't know what actual effect it would have. Even though CHS is primarily designed to be played as PBEM, if this change survives, and it really does cause problems for the Japanese AI, I will need to add a note to the documentation stating that for play vs Japanese AI one of the two "Shinanos" needs to be removed beforehand (the player can choose which one).

Andrew

[bradfordkay]

Do you think that the presence of two Shinano's would cause the game to crash? Otherwise, I'd accept it as a minor bug...

I don't think it will crash (although I should test that), but the concern I have is not that the AI would get an extra ship - as you say the AI needs all the help it can get - but that building both Shinanos would be too much of a burden on the Japanese shipbuilding.

Andrew

[el cid again]

Do you think that the presence of two Shinano's would cause the game to crash? Otherwise, I'd accept it as a minor bug...

A much more likely issue is the air group. Which ship goes to which air group? Since each Shinano has its own name slot, it may work fine too.
And since Shinano has an air group as a carrier (albiet a small one), that group exists in stock, CHS and my own revisions.

Anyway, it will vastly slow down other ship construction. It is the same as if Japan builds the fourth Yamato (which IS building when the game begins and BELONGS in CHS - it is historical after all - let the player cancel it or get it). Every Yamato you build is the steel (Heavy Industry Points) of a LOT of other ships.

It may be better to have two variations of the scenario: For discussion I will call them Midway Yes and Midway No. In a Midway No scenario you get Shinano as a battleship, Ibuki as a cruiser, and those two battleship semicarriers do NOT convert. I think a few merchant carriers also do not appear. In Midway Yes you get the carrier variations. Air groups for Shinano (and Ibuki) can be defined for the version of the ship you are going to get. On the other side, you might also complete the last two Iowas, and there may be other variations (the actual plan shifted during the war, and it is fuzzy in my mind, but well documented). Another name for these two variations might be Carrier Heavy and Gunship Heavy.

I see you are still adding some info...

In future, could you mark lines in which data has changed?

It is my hope to finish today. You may assume that data has changed in EVERY line because, even if the data is preserved, the line itself has moved in most cases. Also, while the line may appear to be the same, it may well have changed location, date of formation, or command affiliation. You may have copies of the data set for review on request. This is to facilitate much easier finding of units - they are in order by category now - for anyone attempting to edit.
Theoretically I am only working on land based air reinforcements - although I just discovered TWO more carrier air groups! Usually it is said that Japanese CVEs didn't have air groups, but at least the first two did.

[Monter_Trismegistos]

Ouch... it will be a little pain for me

I am during little revolution in my database (only for my fun). Mostly sorting and Chutaizing Daitais (I prefer smaller units, and I'm panicly affraid of dividing units - I divided AVG once, and on next turn it reappeared in Karachi while AVG/A AVG/B AVG/C were still on map), so i lost slots nuumbers. Now it will be "very funny" work to add your additions and corrections.

By the way you are doing XXX *) great job!

*) - here should be an adjective describing how great is yor job Ahh how hard is trying be funny in other languages

PS. Questions:
1) Kokatai is different from Kokutai, or it's only misspeling?
2)How are you going to treat squadrons for Chitose and Chiyoda in their CV role - you probably cannot simply asign them to them (My English sucks). They will start as normal land based squadrons? Or maybe attaching them temporally to any CVE without airgroups to make them carrier trained?

[el cid again]

1) Kokatai is different from Kokutai, or it's only misspeling?

Kokutai is the right spelling - and Kokatai or Kokatui are wrong spellings!

Here it is in plain Japanese:

Buntai = Pair - used for specialist formations early but not for fighters and bombers until 1944.

Shotai = Trio - used for most combat formations and some others until 1944 when fighters converted to the Schwarm. At that point a Shotai becomes Four = 2 Buntai.

Chotai = Basic Squadron - often seen in Japanese as "unit" - because Japanese squadrons often are "compound" squadrons - with several units.
This is usually 8, 9 or 12, but can be 14 or 16 - and after 1944 it IS 16 for carrier fighters.

Daitai = Compound Squadron - often 2, more often 3, sometimes 4 to 6
Chotai - this usually is 16 to 48 aircraft - and rarely 12.

Kokutai = Group. This is really hard to explain! It means EITHER:
1) A small independent unit of at least six aircraft;
2) A large group of mixed types of aircraft, usually of Daitai size, but sometimes also including Chotai or even Shotai!
3) A medium or large group of homogenious aircraft - this became almost the rule after late 1942 - but NOTHING Japanese is EVER simple - so it is not quite a rule even then!

Koku Senati = Air Flotilla = Wing. This is usually several Kokutai, and can be medium or large in size. It can have a DHD - a HQ Squadron - and that is usually transports - but it can be fighters (see 22nd Air Flotilla - which has BOTH kinds of DHD - transport and fighter).

Koku Kantai = Air Fleet = Air Division or Air Corps. Confusing because many Japanese translate Kokutai as "Air Corps"! This is two or more Koku Sentais.

Now this is the SIMPLIFIED explanation! Japanese naval air organization has somewhat different operational and administrative terms, and some do not translate. If that is not bad enough, this organization changes during the war. It is very sophisticated, and has some good concepts. If JNAF airmen meet, they know who is in charge, and how to organize for whatever mission. All aircraft have an overall boss - he rides in a bomber or recon plane - he goes in first and leaves last. All aircraft by type also have a boss - that is all fighters, dive bombers, torpedo bombers, or whatever. And there is a NAME for each of those formations, and corresponding bosses! They also tend to form trans-unit units - that is - all the carrier or land elements in one strike (or whatever) will form a unit in its own right - with a name - naturally. And even the use of a trio for fighters is not similar to our use of it - the Japanese trio is loose and functions almost as a schwarm does. Bombers also might modify their formation - Kates used elements of 5 for Pearl Harbor to achieve about a 90% chance of a hit per element - when assigned to drop bombs (just one bomb per plane - they were 16 inch shells from Nagato!).
So the above is JNAF organization 101, not the whole thing!
