The Ki-27 was the army's main fighter until the start of World War II.
In the 1939 Battle of Halhin Gol against USSR in Mongolia, Ki-27 faced I-15 biplanes and I-16 monoplanes, and dominated them with its maneuvrability, downing a total of 1,252 enemy aircraft.
The Ki-27's high turn performance caused the Army to focus almost exclusively on maneuvrability, a decision which came back to haunt them later as it handicapped the development of more heavily armed and faster fighters.
The Ki-27 served until the beginning of World War II in the Pacific. After it was replaced by the Ki-43, Ki-27 continuing to serve as a trainer. It was also exported for use with Manchukuo and Thai armed forces, seeing combat with both.
In Thai service, the Ki-27 reportedly damaged a P-51 Mustang and shot down one P-38 Lightning. Near the end of World War II, a few Ki-27 were equipped with up to 500 kg (1,100 lb) of explosives for Kamikaze duty.

In spite of its excellent turning performance, in combat Ki-27 suffered from lack of armor protection for the pilot and absence of self-sealing or fire suppression in the fuel tanks.
In addition, the airframe could not handle the stress of high speeds and Soviet pilots routinely escaped Ki-27 attacks in a dive. The armament of two rifle-caliber machine guns was weak.

<span class="ev_code_YELLOW">This gnat-like aircraft with fixed landing gear was the JAAF's first monoplane fighter.
To meet army specifications, Nakajima produced a fragile craft with no starter motor, tail-wheel, pilot armor, or self-sealing fuel tanks.
The Ki-27 went into service in the year 2597 (1937) and was therefore known as Type 97 Army Fighter; western pilots would call it Nate.
It made its combat debut on April 10, 1938, when Captain Tateo Kato claimed three CAF biplane fighters.
The Nates then went to Manchuria, the cold climate in which they had been designed to fight. But Claire Chennault had seen enough to warn U.S. authorities that Japan had a new fighter that "climbs like a sky rocket and maneuvers like a squirrel." </span>

http://www.airpages.ru/draw/ki27a.gif

When in mid 1935 Kawasaki, Mitsubishi and Nakajima were instructed by the Imperial Japanese Army to build competative prototypes of an advanced fighter aircraft.
Nakajima responded with a single seat monoplane fighter derived from the company's Type P.E., which it had started to develop as a private venture by the designers Hideo Itokawa and Yasushi Koyama.
A cantilever low-wing monoplane of all metal construction, except for fabric covered control surfaces, the aricraft had a conventional tail unit, fixed tailskid landing gear and power provided by a 650 hp (485 kw) Nakajima Ha-1a radial engine.

First flown during July 1936, this aircraft was followed three months later by the first Nakajima Ki-27 prototype which incorporated minor modifications and refinements that resulted from the early tests of the Type P.E. Service trials proved that the Kawasaki Ki-28 was the fastest of the three contenders, but Nakajima's Ki-27 was by far the most manoeuvrable and, on that basis, 10 pre-production examples were ordered for further service evaluation.
They differed from the prototype by having wings of increased span and area, and the cockpit enclosed by a sliding canopy.
Following further testing in 1937 the type was ordered into production as the Army Type 97 Fighter Model A (Nakajima Ki-27a). Late production aircraft which introduced some refinements, including a further improved cockpit canopy, had the designation Ki-27b. Subsequently two Ki-27 KA1 experimental aircraft were built, introducing a lighter weight structure to improve performance, but no production examples followed.

Nakajima could not have guessed that 3,999 aircraft would be built, by Nakajima (2,020) and Mansyu Hikoki Seizo K.K.(1,379), before production came to a halt at the end of 1942, but the type's entry into service over northern China in March 1938 gave an immediate appreciation of its capability, the Ki-27's becoming masters of the airspace until confronted by the faster Soviet Polikarov I-16 fighters.
At the beginning of the Pacific war the Ki-27's took part in the invasion of Burma, Malaya, the Netherlands East Indies and the Philippines.

Allocated the Allied codename 'Nate' (initially 'Abdul' in the China-India-Burma theatre), the Ki-27 had considerable success against the Allies in the initial stages before more modern fighters became available.
When this occurred they transferred for air defense o fthe home islands, remaining deployed in this capacity until 1943 when they became used increasingly as advanced trainers. As with many Japanese aircraft, thier final use was in a Kamikaze role.

Also, its remarkable that the Ki-27 still in 1944 - 45 was used for bomber interception, even against B-29's http://forums.ubi.com/images/smilies/blink.gif

In Ryuji Nagatsuka's book "I was a kamikaze" theres a thrilling account of how it was done http://forums.ubi.com/images/smilies/25.gif Nagatsuka never flew anything more modern than Ki-43 & Ki-45 during the war, he ended it by making an emergency landing in his damaged Oscar after a fight with Grumman planes (he doesnt mention the specific model). A couple days later Japan surrendered.

I too thought the Nate was coming, along with the similar Fokker D.XXI. Has this changed?

It should make an interesting opponent for the I-16 and a tasty tidbit for the P-40's .50-cal's.

There are rumors the Ki-27 will make it to the sim in an add-on, there are rumors that the Ki-27 will be in a "Russia-only" add-on, and there are rumors that it will not make it at all

I've seen cockpit pics.

The Ki-27 was used throughout the war, and was a main IJA fighter. It's omission renders a flyable plane we have (H81A-2) completely without it's main adversary, especially considering the Hawk 81's default skin is for the Flying Tigers

I've said it before and I'll say it again:

the Ki-27 is the most needed but absent plane in the sim. The Soviet-Japanese scenarios alone are tantalising. Ki-27s against I-16s, both Chinese, and Soviet

Re: Most needed plane.

The Ki 27 was the most numerous fighter in service, army or navy, for Japan on Dec.7, 1941.

Agree about the tantilizing Soviet Union vs. Japan possiblities too.

Also this plane was considered by some to be the most maneuverable monoplane fighter accepted for service by any major air force.

I've been using the P-36 as a substitute but it's not the same at all. I do hope that the Ki-27 makes it into the game; even AI-only would be better than nothing for mission building purposes.

When I noted that the Nate would be an interesting opponent for the I-16, I meant only in the sense of its great maneuverability. In terms of firepower it's arguably the worst a/c you could possibly fly. To think that the Japanese attempted B-29 interceptions with the Ki-27 just shows how truly desperate they were by war's end.

You just have to use the advantages you have against your opponents. I fly the Ki-43 against Beaufighters, Mosquitos, P-40s, P-39s, and Spits fairly regularly. I have shot down more than one of each of these types. It takes patience and careful aim with the "sniper scope", and it isn't always easy to avoid being a moving target when you are outclassed, but it's a lot of fun.

I used to fly a map on-line that pitted Ki-43s against I-16s and I-153s. Not real easy to take down, but it was possible. A Ki-27 should have no problem out turning the 16, and will probably be a pretty good handful for the 153. I can't wait to try it out!

When the Ki43 was initially put into service by the Japanese Army it was almost universally criticized for it's lack of maneuverability compared to the Ki27 that it replaced.
