From where You have 40miles delta between speeds part. Is that experience or You have that from one of devs[:)].

I remember that from a discussion about the ACM couple years back. Pretty sure it was one of the devs. It also shows up though in game testing.

Look what happens when the Corsair shows upearly '43 at 430. We've all been on one side or the other looking at the same combat reports. It ain't the armament creating the difference nor the manouver. It's all speed. 430 .vs. Zero at 336. Tojo struggles as well.

I was driving my car last day on highway and i was driving something 70mph and suddenly i was outrun by another car i think he have 120-140mph, very very fast. There where only seconds until he was few hundred meeter in from of me and i don`t have even chance to see him in mirror so i can imagine how this works for planes. Usually Japanese pilots not even seen what hit him. And even if he manage to avoid enemy fire he have no time to counter attack because enemy was already to far. It suck to be Japanese pilot.

Is there any reason not to skip the Ki-43-IIa and just stay with the Ki-43-Ic as a pure fighter and try hard for the IIb? The IIa has more range and better cruise speed, however it's maneuver is only 39 and the Ic has 46 at the 10k-15k range. I suppose the IIa still has a 39 from 16-20k while the Ic is only a 37. Also, the IIa does have a range +1 better than the Ic.

What do others think and do with the period between the Ic and the IIa?

Thanks

It depend in what kind of mission You see them
When flaying as escort with bombers bombers there should be no difference at all they bot dieing equal.
When at sweep or CAP You must remember speed is a key. If i understand PaxMondo correctly maneuverability start to have impact when planes speed difference is ~40mph or smaller

On Your place i will go forward IIa

Always keep in mind that whatever airframes you decide to use, there's a concurrent need for specific engine types to power them. And that can be complicated by the need to use those same engines to power other airframes. So once you have made your decisions, it might be useful to use my Japan Airframe and Engine Planner spreadsheet (see third link in my sig) to figure out what the impact will be on engine needs, and to make plans accordingly (it's very easy to run what-if scenarios).

We can compare Ki-83 and Shinden only for statistic. But one is army and second navy fighter so for game economy, discussion like that is pointless
I don't consider it pointless. Allow me to elaborate a bit on my thoughts why.

As the war moves into '45, I tend to ignore the whole IJA/IJN thing. Everything is moving back to the HI for defense and there isn't much fleet left so everything is LBA.

Having said that, I'm looking for specific fighters to perform specific roles. To me, there are 3 roles that need to be filled:
1. A2A Fighter
2. A2A 4E
3. NF

A2A Fighter
Meaning, what am I going to send toe2toe up against the Stangs and Bolts? I don't beleive in ablative fighters, so that's out for me. There are only a few choices here as you need to be within 40 of the Stang which is at 487 to avoid the heavy delta speed penalty. That means 448 min, and that means: Shinden, Karyu, or Shusei. Shinden is generally my choice, but I sometimes go for Karyu. Having chosen Shinden, it means I'm putting the other two roles on the IJA side because I need a LOT of these fighters and fighter groups.

A2A 4E and NF
These have to be at least 20 faster than the B-29 (364), looking for +385. What you can't catch, you can't hit. And the more armament, the better. Again, this is a short list: Ki-83, Ki-84b*. Armament between these two is a wash. Ki-83 is faster ... 46 faster which is a lot. It is also exactly 2x the cost as it is a 2E. I consider this a coin-flip. Personally, I don't think it matters that much. I prefer the Frank, but I readily accept that the 83 is a fine choice.

So, in the end, all of my IJN fighter groups will be Shinden, all of my IJA groups will be Franks. Tiered CAP. With production focused, I can build lots. I also have my production spread out so it is hard to take down. If I did my 42/43/44 builds right, I have lots of potential kami's in my pools. I think I can keep the allies off the shores of the HI. Keeping thrm out of Korea will be harder. [:'(]

These are all SR3 fighters. Oh well, they are fighting over their bases and the allies have to fly from far out. And by mid 43 every base in the HI is maxxed out, right? SR3 is not an issue unless I let my Base Forces and Air HQ's get caught out on the frontier leaving me naked at home. In which case, SR3 is really not my biggest problem, is it? [;)]


* you could include Karyu and Shusei again in this if you wish, but both are SR5 and you need to think that through carefully before you commit to either one.

Anyway, just my thoughts.

A very helpful post, Pax. [&o]

I'm not sure if I agree with the absolute tone of your selections (e.g., all or nothing Franks for IJA), but it's clear you've weighted the choices well.

The Oscar Ic is a nice dogfighter, but a poor frontline fighter against the Allies armored aircraft. It is woefully undergunned. Tojo IIa is better (also with SR=1), but the replacement of two small rifle caliber MGs with two heavy MGs in the IIc really makes a substantial difference.

The IIb, with its incredibly inaccurate cannon, is actually a step back from the IIa in terms of armament. Most players hurry through the Tojo IIb in pursuit of the far better IIc.

So, scenario 2: I have the Ic at the onset. With R&D, I will get the Tojo IIa in either May or June latest. Until then, the Ic can, with A6M support, hold the line.

I disagree here. Tojo IIb have actually better armament, because it does have center line 12,7 mm MG. So the accuracy of main gun is much better than IIa. Secondary gun of both models is crap, so it's the 12,7 mm that matters.

But he was asking about Oscar models, not Tojos. I'd say japanese player must replace Oscar Ic as soon as possible. And Oscar IIa is much plane than Ic, and arrives 7 months earlier than Oscar IIb.

The accuracy of the wing-mounted 12.7mm in the Tojo IIa is not bad. The two smaller caliber centrally mounted MGs have an excellent accuracy-one not achieved with a "never hits" larger caliber cannon in the IIb. So, would you rather have the additional two small caliber MGs with a slight decrease in accuracy of the 12.7mm guns or a cannon that never hits and only two 12.7mm guns? I'll take the two smaller MGs-at least I know that I can damage some airframes with it regularly.

IIRC, SuluSea 'sandboxed' the Tojo IIa v. IIb against B-24s. As anticipated, the IIb was poor, the IIa better. IIc was the best of the bunch. Maybe I'm losing my mind (always a possibility, I can assure you), but I thought this had been demonstrated with testing.

Yes, the Oscar IIa is superior to the Ic. In scenario 2, I will have access to the Oscar IIa sometime in late summer 1942, some three months after access to the Tojo IIa. I'd choose the Tojo IIa for the intervening three months, rather than stick with an Oscar Ic-IIa upgrade later that Fall.

As for leapfrogging the Oscar IIa and waiting for the IIb? No. The Oscar IIa is a good plane, build (and deploy) it sequentially. Lastly, consider overbuilding it and the Oscar IIb for kamikaze purposes later in the war.

Afaik those tests made by zulu are showing, pretty clearly, that ki44b is less effective against 4Es than ki44a

The KI43-Ic becomes useless very soon. Wile the later oscar models, starting from IIa, carry 2x250 kg bombs and so can be used as kamis late in the war, the Ic doesn't and its utility remains confined to ablative armour for suicide offensive escort missions

Karyu is tough with SR5, but if you can field 400 of them the allied sweeps will have a really, really bad day. However, it is a unique R&D along with a unique engine. Takes a lot of investment. And of course, there are tactics to deal with it. There are no silver bullets.

Shinden SR3 isn't that bad for me. I can easily deal with it in the HI by cycling groups. At 466, only the Stang is faster, but they have (hopefully) had a long flight already so I am facing slightly fatigued pilots and a/c. Shinden and Karyu have the best armament in game for the IJ. 4 CL cannon. You can only wish they were 4x20mm instead of the 2x20mm and 2x30mm. Still a good punch.

Thx for that info. I never managed to get my games to that late stage unfortunately, so I still am deprived of the opportunity to use these fancy toys. No silver bullets, but at least some out of usual to play with. I should probably just start up a late scenario at some point...

What again was that Japanese counter-piece to the Me-163, the Komet? I forgot. I never invested anything in researching it so far. Have you also tried it? Do I guess correctly that it is rather poor compared to Karyu or Shinden?

So let me get this straight ... people think the Tojos are better than the Oscars? That is what I should be researching/producing in 43 onward? Up till now have focused on the Oscar and have the Oscar IIa in full production and want to get to the armored version.

Do 'em both would be my advice. Post 1943, there are better airframes to research (N1K1-J, Franks, etc.), but the Ki-44IIa-IIc (Tojo lines) serve as valuable interim mid-war fighters to stem the tide against the Allies' 2nd generation fighters.

Oscars are very good for their range in the escort role. Nature of the beast that escorting fighters are slaughtered outright, but at least there's a chance you'll get your strike package through at range. Tojos, with their limited range, aren't as useful in the escort role.

You should pre-plan your kamikaze production too. Oscar IIa-IIb, with 2x250kg bombs, speed and range is a good candidate. They're capable of ruining the Allies' day if you connect with 'em.

Thanks for the great advice, I will not slack on my research/production on the Tojos anymore. What should be be producing as airframes to best combat the allies HB threat to my production cities in 44-45?

Sounds like there's a trade off between the maintenance/AB capacity of the 2E Japanese fighters vs the 1E counterparts?

Seems like the consensus is the Franks?

I found the Allied night fighter P-70 Havocs to do well disrupting and even killing a few incoming strike planes. There was usually the radar message in the combat report. Although nothing like late war strike size and of course IJ planes not having any defensive capability, I'm not sure the same would be true for the IJ night fighters in the Home Islands in 44-45.

I used my first Beaufighter nightfighter squadron to protect Rangoon (pilots around air combat skill 70). They began to score almost immediately at night and are about as useful as my insane concentration of heavy AAA there (~ 2 kills each per substantial night bomber attack).
Some other times I used them for very successful LR CAP over convoys, since only a G4M threat was expected.

What are the better night fighters that Japan can make in 42? 43? 44-45?

Thanks


You do not need any night fighters as they really do not work. Putting any old fighter up at night works just as well. You will not shoot anything down but the mere presence of any fighters at night will greatly lessen the impact of the bombing attack. Night fighters are total chrome.

An arguable position to hold before the last big official path But with the increased importance now given to having airborne radar to locate the enemy (planes and terrestrial targets) at night, perhaps no longer such a definitive position to hold.

I noted if i fly br4e bIII w/ b29s from the same base they all seem to find the target at night! Using beta 1121

Here are some numbers and dates when I got the plane in my PBEM game. We are now at July '44.
Feel free to poke fun at my production as this is not only the furthest i have ever gotten in a WitP game but also the very first time as Japan [X(]. So this is most likely NOT an optimal setup lol.

The first number is in the pool, the second is Build/month. The last number is the date they were available. If a plane is not on this list then I did not make any and converted their factories to one of these types.

Total Aircraft 6,790 Build/month 2,158

A6M5c - 236, 340, 12/43
Ki-44 IIc - 122, 280, 9/43
Ki-84a - 86, 200, 6/43
J2M5 - 208, 160, 3/44
N1K2-J - 87, 148, 6/44
Ki-67-Ib - 9 (nine), 146, 6/44
P1Y2 - 399, 140, 10/43
B6N2a - 16, 110, 5/44
D4Y2 - 52, 85, 3/44
E13A1 - 56, 80, 12/41
Ki-49-IIb - 69, 70, 6/43
H8K2-L - 108, 55, 7/43
Ki-49 II KAI - 0, 55, 5/43
H8K2 - 47, 50, 3/43
Ki-46-IIIb - 83, 41, 12/42
A6M5d-S - 33, 20, 2/44
Ki-45KAID - 31, 20, 3/44
C6N1 - 2, 12, 7/44

I have the following turned off, but can produce if needed
G4M2 - 338, 50, 10/43
G4M2a - 0, 65, 6/44
J1Ni-C - 98, 20, 11/42
Ki-46-III - 167, 10, 1/43

Engines I have the following that are in production. Everything else was converted to one of these types.
Ha-60 - 93, 100, 3/42
Ha-32 - 541, 1,170, 12/41
Ha-33 - 407, 360, 12/41
Ha-43 - 199, 40, 2/44
Ha-34 - 390, 340, 12/41
Ha-35 - 19, 650, 12/41
Ha-45 - 102, 660, 6/42

Not producing but can if needed
Ha-44 - 82, 100, 3/43

Just some other 'fun' numbers

Total air losses
Japan - 26,260 planes (from all sources, only 12,846 from A2A. The next largest was from ops, i.e. getting bombed to death [:(])
Allied - 15,634 (5,587 A2A)

I still have 100's of old plane types that are no longer active, like over 300 Vals. So these are included in the Total Pool number above.

Hope this helps to see where at least one Japanese player is in a late game situation [:)]
