Japanese Opinion on the Bf 109

Jun 04, 2021
Hello everyone, welcome back to the history of military aviation. I'm your host Chris and I have something really special for you today and it's a summary of Japan's evaluation of the BF109 during World War II and the conclusions they drew from the comparative fights between some. of their machines and the bf 109 and this video, well, it is courtesy of one of you, who is a viewer and supporter of patreon and has been responsible for translating much of the Japanese material and Japanese sources on the subject into English, that now It is giving me the opportunity to convey all this information to you.

Yes, that's fantastic, taken directly from the original language. That's how we do it here in military aviation history. Can there be anything better than this? No I dont think so. unless you have a pot of sauerkraut with you, so yeah, this video credit really goes to quas. I'm sure you'll appreciate what he's done here because yes, it's just fantastic, as you know, it was quite common in World War II for the allies and The adversaries tested each other's equipment to see if there was anything new and if they would ever something could be learned from the team on the front.

japanese opinion on the bf 109...

Now this story is not that different and when a new generation of German fighter aircraft appeared in the late 1930s, Japan was interested. The story I'm going to tell you today involves the Japanese military, their air service was, of course, different from the Japanese navy air service, but when they found out that the Germans were developing the BF-109 and the Heinkel. 112 well, the Japanese military attaché in Berlin in Germany sent a telegram to the military in Japan in September of '39 giving information about these aircraft and specifically what would be required to import them to Japan.

The first telegram number 373 was about BF109, model 109. The Fuchsia Bioshock aircraft has recently been equipped with the Daimler Benz solid injection model 601 engine and has demonstrated high performance with a maximum horizontal speed of 570 kilometers per hour at an altitude of 4,900 meters. Production rights will not be sold unless accompanied by 30 aircraft. or more and the price per plane is 260,000 marks in the future this plane will be the fighter of the German air force and if the production rights are purchased the price is about 700,000 marks and if two or three planes are bought as shows the price is still 260 thousand marks then telegram number 374 was about the Heinkel hg 112.

There is an offer from Heinkel to the army to sell 5 He 112 fighters the engine is Diamondband 601 the maximum speed of 570 kilometers per hour at an altitude of 4500 meters the rate of climb is about 5 minutes at 4,000 meters it was reported that the price is 185,000 marks per plane for the purchase of nine planes and it is not necessary to buy production rights in response to both telegrams army aviation The barracks General responded that although the fructose biological vector model is recognized as a valuable research aircraft, it is regrettable that it cannot be purchased due to its high price.
We know that the Heinkel 112 can already be obtained for research as the navy purchased this aircraft in In short, the BF-109 was not purchased for study due to the price and also the conditions involved and the Heinkel 112 was already in Japan because the navy had ordered it and the army could perhaps borrow from the navy for being optimistic for a year. Later the situation seems to have changed somewhat, a handful of Bo119s were successfully ordered from Germany in 1940 and, upon arrival in May 1941, they were assembled and then slaughtered to have a comparison flight and also a dogfight by means of a simulated dogfight of course between the bf109s and a couple of


army fighters, let's start with some of the basic information for this test.
This test took place in July 1941 and involved a German B419E7. The e7 was the last main production variant of the e model of the 109 and in 1941 this was increasingly replaced in the luftwaffe in germany of course by the newer f model, however it was still used as a fighter-bomber and, Additionally, the E7 would receive quite a bit of service among some of Germany's European allies, the Japanese military had a specific interest in this test and it doesn't seem like they were actually looking for production licenses, but simply wanted to see how the aircraft currently fares against modern high-speed fighters that were out there, the BF109 in that constellation was simply a substitute for some of the types of aircraft that Japan expected to encounter once they launched their offensive in the Southeast Asia and Pacific theater and that would primarily be then, of course, British and American types and you have to remember that in July 1941 Japan is still not involved in what we Westerners like to call the Second World War.
Instead, of course, they had already taken territory in Korea and Manchuria long before this and had been involved in China, but the kind of World War II time frame we're in. I would like to think that that just begins for Japan in December 1941 with the attack on Pearl Harbor and of course they are offensive in Southeast Asia. Before we get to the comparisons, I thought it would be really interesting to see what the Japanese really thought about the bf109, so let's get into that first, but keep in mind that throughout this video, the Japanese when testing the bf109 apparently had some problems with the engine and it was not operating at full capacity, which equates to slightly worse performance than the The e7 was able to do so in July, it flew for the first time hand in hand with pilot stur, a Messerschmitt test pilot, and comparative tests were carried out with a type 79 fighter, the Key 44, the Key 45 and the Key 60.
As a result, the acceleration force was considered to be excellent, but the other performances were not as expected, in particular the performance in Air combat related to the difference in design philosophy and was said to be no match for Japanese fighters at all as a result of comparative testing with the Key 44. and T60, the BF109E easily loses speed when climbing or performing air combat maneuvers, however, the special flight in the aerial gunnery tests subsequently held at the arcane army aviation school clearly showed several outstanding aspects, such as excellent performance in dive and the strength of the fuselage, also demonstrated the structure.
To be a great reference for mass production, the BF-109 was evaluated by the Arcano flight school. The low landing speed makes it difficult to lower the tail and when landing in a horizontal position, the bounce gradually becomes severe and the airframe tilts, scraping the wing. on the ground because it is an unknown phenomenon for Japanese pilots Aquino made several mistakes and damaged the aileron each time Captain Ahamaki knew the trick to land without bouncing and was praised by the civil pilot who arrived in Japan with the B of 109. next Willisteur Germany also sent another pilot Oberloytman and Fritz Lozekite who became military attaché until January 1942 and it seems that at least in the sky he was a bit of a troublemaker and became the center of quite a few discussions according to the prevailing


at that time. considered that Lozekite was not familiar with the simulated air battle method on the Japanese side switching between superiority and inferiority and the performance could not be compared because he ignored the regulations and focused on hit and run tactics, however, as So can be seen in the ki-27 versus beo-409 duo, it seems that while the lucikite was carrying out the tests according to the rules of the simulated air battles on the


side, some of the japanese pilots had negative comments about the logos of the kite. performance during these combat tests, captain aranaki said that that problematic guy doesn't make sense because his tactics are different and this shows the complexities involved in taking a pilot who is used to a certain combat environment and then putting him in a completely different and add to the Of course, this is a test environment now where they are simulating dogfights and essentially telling you what you can and can't do based on the test parameters that the Japanese are used to Fritz Lozekaide.
Well, at this point he had already participated in the Spanish civil war. In the war, he had been there during the invasion of Poland, the invasion of the Netherlands, the battle for France and he also flew during the battle of Britain and claimed a couple of kills throughout this time and yes, he flew the BF109 the way it flew. and I guess he wasn't going to let anyone tell him what he can and can't do with the plane that loses the kite. He introduced German-style rotter schwarm aerial formation tactics to the Japanese military. The maneuver of two and two platoons of four aircraft called rot tactics.
It was later taken up as a research topic at the Akaino flight school. Now let's take a look at how the BF109 fared against some of the other machines that the Japanese used well, specifically the Japanese Army aircraft, and that was the key 27, the key 44, and the key. 60. Now let's take a quick look at the schedule of the simulated dogfights, as you can see, here we are only comparing the BF109 with the Japanese army aircraft, starting with the key 27, an older model, moving on to the newer models of the Key 44 and Key 60. Also tested was the Key 45, which was a twin-engine heavy fighter.
I don't have any specific data on that test though, although somewhat surprisingly given its old look and also somewhat dated performance, the Key27 actually became a pretty important aircraft to test. Bf-109 and that was because many of the Japanese Army's air service squadrons were still equipped with this aircraft, so the Japanese wanted to see how this seemingly obsolete machine would perform against a more modern high-speed fighter and these were the conclusions. Overall, it can be seen that the Kia 27 is superior to the BF109e only in turning performance; It is impossible for the Ki-27 to take the initiative and fight unless it is a surprise attack, even if the Ki-27 managed to attack the B409 from a dominant position, the B409 would be able to move away and counterattack the Ki-27, regardless of if in level flight, ascend or descend maneuvers, taking advantage of the difference in speed;
However, if the Ki-27, which excels in turning performance, could be put into low-altitude aerial combat, it appears that victory would be possible because the BF109e's performance advantage is limited to Oberloidna and Lozekite commented that I think the BF109e can shoot when the key 27 tries to turn the key 27 turns frequently, so I can't dive into it, Captain Zakagava said that the ki-27 has a chance to be shot but has no chance to shoot, so it is interesting that these conclusions were taken with a rather positive spin since the Key 27 was still supposed to be capable of defending itself or being able to defend itself against modern fighters, the Japanese military essentially said that we can still trust these machines for the next few operations, which you know, I can see their motivation and try to spin it this way since they still have a lot of these planes. guys in service, but that's really putting a bit of pressure on him.
The comparison flights between the Key 44 and the BF-109 were perhaps the most important for the Japanese military because if the Key 44 fails against the BF-109, then the Japanese military then. knows that it is in trouble because this was one of its promising fighter aircraft in development and has already come under severe criticism from some parts of the japanese army air service, especially the aquino aviation school, the speed and performance of maneuver of both models are the same. The key 44 is superior tilt power and the BF109e is superior in diving performance. Judging by this, the Key 44 has the performance to compete with the BF109e if the pilot's skill is similar, here the side that makes the best use of the aircraft's features wins, captain. ishigawa said that the b409e has no merit compared to the key 44 in terms of performance captain ahramaki said that it can be said that the bf109e is no different from the k-44 the german village duraset if you can fly this plane aviation Japanese military will be the best in the world, the ki 44, had been harshly criticized and much of this seems to arise from the general expectations that part of the Japanese army air service had in emphasizing maneuverability and close-in and air combat performance in the machines above the kind of high speed hype, you know, quick passes, boom and zoom, kind of combat approach, that's not to say that the Japanese weren't completely familiar with that kind of combat close to high speed combat or that they didn't care about the fact that they really wanted it.
Seeing how the BF109 performs against their own machines shows that they were quite open to this idea and that their next fighter designs were also going in that direction, but there was still an institutional bias in some areas that seemed to emphasize that maneuverability. and the old way of thinking or theold school way of thinking, which is actually something that was quite prominent in many nations before they entered World War II, with this test now and with the comparison flights that they were doing, they actually realized Well, the K-44 with this aircraft had a pretty solid platform and after that test, the criticism or much of the criticism against this machine evaporated and disappeared and they realized that they actually had something here that could work. for them. and alias 44 was thus sacrificed to take a greater part in the next sovereign operation.
The Key 44, which was severely criticized by the Aquino aviation school for failing to be used as a fighter due to overemphasizing high-speed performance, was immediately erased of its stigma. After the evaluation of his simulated air battle with the BF109 from this point on the controversy of the Aquino Flight School negative


of the Key 44 disappeared and the evaluation of the Key 44 turned 180 degrees the comparison between the Key 60 and the b49 was also really cool because both planes actually used the same engine and the bf109e used the daimler benz 601 and key 60 and also later the key 61 used the license version of that same engine.
There is not a big difference in speed performance between the two, it seems that the key 60 was slightly inferior to the BF109 in acceleration for climbing performance. There is no difference in climb speed, but the Ke60 may have better climbing performance on a zoom climb than the BF109e. was still superior in dive acceleration, the Key 60 had slightly better cornering performance. The Key 60 was supposed to be able to compete with the B109e, which was good news for Japan because it meant that while it was still reliant on a foreign inline engine design, its own aircraft designs were on par with what that they were seeing in different countries, however, the Key 60 was not put into production and much of this is probably due to the fact that still during this stage it had quite a few problems with the design and also because it didn't really give the Japanese nothing extra and nothing that they really thought they needed at the moment and the Key 60 was supposed to be a kind of heavy fighter, a heavy single engine fighter but with a lot of firepower and used as a high altitude interceptor. which it seems was not really the focus for Japan at this time and therefore the Key 61 was put into production because it was also better suited for the local air superiority role that the Japanese military assumed it needed in the coming operations, so having taken a look at all of that, I think it's really interesting, you know, it's fascinating to see how different countries have completely different conclusions, they test them differently, they have their own reasons and their own justifications for the conclusions that they have and personally, I think it's, you know, looking back at the test, I think it's a little cheeky of them to say, oh yeah, the ki-27 is still there somehow, you know, it still feels as if they were pressing him at that point against the moderns. machines, I don't really see them being that capable, but of course you also have to remember that not all the machines that were in the area in this Southeast Asia and the Pacific regions that the Japanese were facing, you know? all those machines were the most modern types, let's look at the evaluation of the ki-44, key 44, key 60 here, I think this seems fair, you know, key 60, of course, did not materialize, instead , we had the key 61 with the It also has the same engine as the BF109e and it actually seems like overall on paper it had slightly better performance than its German cousin, but yeah, I hope you all enjoyed it too .
