While browsing for A6M info, I decided I'd check out some specs on my favorite IJA fighter, the Ki-61.

Started as a sideline project to Kawasaki's Ki-60 fighter (appearing mostly the same but with a more "bubbleish" canopy), the Ki-61 became the airframe that ultimately went into service.

According to this information, the Ki-61-1-Ko, or Ki-61-1a had two 12.7mm guns in the nose with two 7.7mm guns in the wings, unlike the cannon armanent we have currently. The Ki-61-1-Otsu introduced a quartet of 12.7mm weapons, but also had provisions to mount MG151/20 cannon in the wings; 388 were modified in the field or on the assembly line to accept these weapons. Additionally, the Otsu should be a '42 plane, right after the Ko.

The definitive variant was the Ki-61-1-KAI-Hei, which brought about a redesigned rear fuselage and 20mm guns in the nose, as well as 12.7mm guns in the wings.

In total, Kawasaki made 1,380 Ki-61-1-Ko (Ki-61-1a) and Ki-61-1-Otsu (Ki-61-1b), coupled with 1,274 Ki-61-1-KAI-Hei versions.

Capable of 360mph (580kmh) at 5000m, with a 7 minute climb time to 5000m. A very well balance fighter for '41 and '42.

count the Ki61 as non existent in PF3.0 - its bugged like hell . and btw, the first combat appereance of the Ki61 was April 1943 (!) , at NewGuinea.
the first prototype flew december 41 , so i wouldnt count it a 41 plane http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Yes I've seen that thread and I know the deployment date. For '43 it is a bit outclassed, no? http://forums.ubi.com/images/smilies/16x16_smiley-tongue.gif

the USAAF still flew P-40s and P-39s there , well http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

and a Ki-61 is sure a better threat to also more modern US fighters that apeared 1943 over NewGuinea , P-38 and P-47D , than an Oscar II http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

Oh I think a Oscar is plenty threatening to the likes of many allied players now.

BTW, by '43, most of the Airacobras had been eliminated, and primarily the 5th Fighter Command was using a mixed bag of P-47s, P-40s and P-38s.

Just an interesting sidenote, but an early (before deployment) Ki-61 attempted to intercept the Doolittle raiders, but failed to catch any. Probably the type's first use in "combat." http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

By the way, I'm pretty sure all three versions of the Ki-61 we have should not have droptanks or bombs. These were introduced with the modified wing of the Ki-61-Tei (or KAIc, as many English sources call it).

Might be why the Ki-61s are listed as '41/'42 planes, unless they're listed as production dates rather than supplied dates.

That sounds more like the way it should be Koro. The Ki-61 Otsu that we have I believe is the one that is retrofitted with the 20mm MG151/20. Its not on the plane in the game right now but thats what it should have.

Looking forward to the patchified Ki-61!

Ki-61-Ko's and Ki-61-Otsu's were both modified to take the MG151/20s. The 3 Hiens we have in game should be essentially the same except armament, minor weight differences, and a small bulge on the top of the wing for the MG151/20-equipped Hiens.

Well hopefully the patch solves these things for us. That'd be great because this looks like a fun fighter to fly...

well, there are different sources around about Heins varaints names.
Saxon (the builder) and Maddox decided that way:

Ki-61-Ko(a) with 12,7mm in fuselage, 7,7mm in wings , rectractable tailwheel

Ki-61-Otsu(b) with 4 12,7mm , non retractable tailwheel

Ki-61-Hei(c) with 12,7mm in fusealge, 20mm MG151 in wings , non retractable tailwhell.

Not sure about the tailwheel. I was under the impression that this began with the Ki-61-Tei(d), along with the other fuselage modifications made.

that looks like a "short fuselage" Ki61

Yes, after posting that, I did a little research last night. I can't find any text references to the earlier Hiens with droptanks/bombs, but I also found several images of "short-fuselage" Hiens with drop tanks, most of them apparently in late-war homeland-defense service. I'm wondering if maybe a field mod was done to retrofit earlier Hiens with wing store provisions.

You forgot to mention the version of Ki-61 with a pair of wing 30 mm Ho-155 cannons, a specialized bomber killer that came into production in December 1944. This version was made on the base of the Ki-61-I-Tei and also had 19 cm longer nose and a non retractable tailwhell. This version is known as
Ki-61-I-Kai D(in English trascription).
