Cid,
I think that your points on the planes are, generally, good but there are a few flaws:
REPLY: And one omission: I should have said your opposition to the ASW Kate was flawed - because it is the ONLY CARRIER ASW plane! And YOU have ASW carriers which use it in EOS (vice the Ki-76 in other scenarios). It has MAD and you WANT this plane - trust me.
1. All of this upgrading etc costs supplies... supplies you want us not to waste and which I'm trying to conserve by delaying upgrading until September 42 when we can do a single upgrade of Ki-36s ( and others) instead of two upgrades ( costing twice as much supply).
2. If we have planes in the pool then we might as well use them up so long as we can find niches in which they can survive and achieve goals.
REPLY: You are not considering pilot costs. Nor the efficiency of fewer types. Different types are not nearly as easy to manage. Even so, there are niches: I mentioned training units - which if used as such (and not doing so is gamey - and probably unwise for pilot skill reasons) are both survivable and have no need for line planes. I usually use civil air transport the same way briefly - downgrade to Ki-34s and never use them in combat - UNTIL I have more better transports than I can use. [This was historical practice on both sides early war].
3. The strategic strike model focuses on number of bombs dropped, not their weight such that planes carrying many bombs are more effective than planes carrying fewer but heavier bombs.
REPLY: To the extent that is so, it is gamey to exploit it. The Ki-36 carries the smallest bombs in the game - 5 of them. If you are not attacking a light target - it is not permitted under the RHS general house rule: a real commander would not use it as a strategic bomber (your term). We don't do things like that. I don't think this is as so as you think it is - I tampered with the bombs. In RHS these tiny bombs have very little value except against soft targets. And the value 9 is incorrect: it is only 5. [verified]
E.g. The Ki-32 carries 9 bombs and is thus three times as effective at resource attacks as the Ki-21. Sure the Ki-21 has more range and more durability BUT over China there are more than enough bases within 6 ( or even 8 hexes) to make the Ki-32 ( of which we have about 500, including the pools) a really viable bomber for the anti-resource campaign. Obviously we should expand production of the Ki-21 BUT we shouldn't do so and think it is the answer to all our problems. The Ki48, 32 and 36 all have excellent niche roles, albeit mostly over China.
4. Ki-36 and Ki-51 being junk.I have 93 Ki 36s in the pool and 60 Ki-51s. I won't upgrade from them to Kates and Vals ( which are rare) until the Ki-36s and Ki-51s are used up.
REPLY: I want priority for naval bombers. But I want an IJA dangerous to ships: here is the deal: I will upgrade these planes when I think I have naval bombers to spare for them. I also want IJA pilots to survive. You have over 40% of our airpower - and I don't want you to run out of pilots as soon as I will.
I am just arguing that you need to be open to the benefits of the older planes in China and other subsidiary theatres in the first few months while production of the necessary replacements is ramped up.
REPLY: We must use some planes (notably Ki-27) far longer than I like. I want you to optimize to minimize that time.
6. As regards the Me-264... I think your maths as regards comparing the Me-264 to a Ki-21 is flawed. A single Me-264 costs 90 HI ( 4 engines + 1 airframe x 18 HI ). A single twin-engined plane costs 54 HI ( 2 engines + 1 airframe x 18 HI). So the Me-264 only costs 66% more than a Ki-21. It doesn't mean that one should immediately stop the Ki-21 obviously though but it does mean that the Me-264 isn't quite as expensive, relatively speaking, as you seem to believe.
REPLY: Per the manual, your math is flawed. It says the ONLY cost of an aircraft is engines. Engines indeed cost 18 HI each. Airframes cost 18, 36 or 72 HI - period. No airframe cost. So it say.
Your analysis of Me-264 production vs fighters is flawed. A fighter costs 36 HI ( 18 for the engine, 18 for the airframe) so a single Me 264 costs the same as 2.5 fighters, not 4. As to the 115 planes per month. That was illustrative of the relative cost of an Me-264 vs a CV so as to provide context for the discussion. It wasn't intended to justify production of 120 per month

.
REPLY: I would prefer your analysis to be correct - and I disagree with the Matrix system. They refused to use the system I gave them when WITP was proposed - or they used it and grossly simplified it. They ignore lots of costs in the aircraft cycle. Even so - a full blown system would make the ratio WORSE than 4:1!
8. Transports.
Looks like we are in substantial agreement as re: focussing on a mix of L2s and G5s for the army... I understand what you are saying about using Mavis and Emilys flying boats as extempore transports so as to maintain the maximum recon capability BUT there is a 42 plane flying boat unit. Surely that could be equipped with the transport version as it is massive overkill for a patrol unit. As to all the other units, sure, maximise your patrol capability. That makes sense.
REPLY: Note in RHS a TRANSPORT FLYING BOAT DOES have recon capability. What it lacks is armament. [Curiously - they sometimes depth charge submarines! So do wholly unarmed recon planes! Some code. These may be rationialized as improvised attacks.] The transport flying boats actually are unique: they may deliver troops or supplies to an undeveloped airfield! They have great range as well. If they were only cheaper - or if I only had more airborne troops...
9. Floatplane fighters...
Well every time you lose a Pete you lose a 70 Exp pilot... Its your navy you can do with it what you wish... I prefer to risk a bit of minor damage to a few DDs than continue to lose my precious pilots in this way. You draw the line in a different place, that's fine. it is your navy after all.
REPLY: DDs are not pawns for Japan. They are the minimum "major warship" for cause. And who says I am protecting DDs? I am protecting capital ships, transports laden with IJA troops, even aircraft carriers: stuff like that.
10. Kamikazes.
LOL! So under no circumstances would you use kamis EVEN in the face of uebercap where your only chance of getting a hit was to sneak a few Oscar IIs in above their CAP ceiling and dive down into their elevators?
REPLY: Well - that was Adm Yamamoto's position. It was not an option while he lived. Perhaps AFTER I am killed we can consider it! [I AM Adm Yamamoto - so we can tell.]
Well, in that case I think we might see the army becoming the kamikaze wing of Imperial Japan in 1944

. I love kamis... Obviously I prefer conventional attacks so long as they produce results. Once they stop producing acceptable results though I will switch over to kamis.
REPLY: I posted that somewhere already. But it is foolish use of pilots and planes (you realize they don't come back, right?).
11. Fighters.
Ok I'm quoting from V6.15 ( latest version I have). The Ki-44 III is listed as having a top speed of 394. The A7M2 is listed as having a top speed of 390. Sure the A7M2 has a 2 mph advantage in cruise speed but surely it would make more sense to base air intercepts on top speed as I would imagine most planes trying to intercept another plane making for a precious CV would use top speed for the intercept.
REPLY: Oddly - code considers cruise speed a factor. And possibly rightly so: a flight being intercepted may not know it is being intercepted, so it is at cruise speed. The faster that is, the less likely it is to be intercepted. I can't read the code - I only know I was told (by Mike Wood I think) it matters. I am guessing how.
Maybe you can explain the A2A model a bit more as I always thought top speed was the most important thing. Now you seem to be saying it is cruising speed ( which seems a bit unlikely to me).
REPLY: Well - I posted just that - and got corrected (partially).
Ground combat issues:
13. Aleutians.
Ok, we agree on this.
REPLY: Except YOU should do it! Northern Command is YOUR flank IMHO. And it gives your naval planes a job. And you love strategic bombing - from the North you can do it.
14. Pearl.
It appears we agree here. The only question is whether you charge into the guns on December 11th or go for the more gradual approach of taking Hilo and Kona and blockading, running down supplies and the defending coastal defences with concentrated bomber raids before landing sometime in February or March.
REPLY: It is necessary to have all nearby air bases and ports. Too many problems if you don't.
15. Oz.
Not to mention I NEVER will build a base in NORTHERN Austraila that the Allies can use (when captured) to bomb Java.
I think this is short-sighted. The Allies will be able to build these bases up with their engineers + bulldozers in almost no time when they take those bases.
REPLY: That is what Joe says. It is too bad - and a flaw. Doesen't matter - every week of production unmolested and shipping unmolested matters to us. It is unwise to build up bases for the enemy. This is my fundamental principle:
most of what we take that we don't need is NOT built up - we just hurt them retaking it - AFTER which they START to build things.
OTOH if we take some of these bases we can unleash our strategic bombers on their resources, repair shipyards and HI.
REPLY: We have the range. Bases are not a big problem. And the one thing we don't want is enemy bases in range of Java.
16. China.
The vital strategic goal of clearing the rail-lines can be achieved once Chinese troops begin to starve and troops begin returning from India
REPLY: You don't understand this. This is a fundamental priority. It grossly frees up shipping and it grossly messes up an enemy strategy focused on sinking transport ships. You can not achieve this soon enough. Soon enough would be about Dec 10, 1941 in my view. [Deliberate exaggeration - but you get the idea]
( minus the troops left there as a garrison force... not all that many troops since they aren't expected to hold India, just conduct a fighting retreat to Ceylon and the southern coastal ports and then be evacuated from there... while Me-264s bomb as many of the resources as possible.
Sid, I'll post an economic analysis later... I will assume a 50/50 split initially with aircraft production split 50/50 between us as totting up who was producing a given plane and using it would just be too much of a headache on a per turn basis.
REPLY: I start with a bigger air force. I get more additional air units. 50/50 is not going to work. I will send you the data (roughly - it is CHS era when I created it).
