Not very Korean against the Su-35?

Not very Korean against the Su-35?

We can say that the program to create a new South Korean KF-21 fighter is moving as confidently as the aircraft that made its first flight two years ago and is now in mass production.

World experts evaluate the KF-21A as a 4++ generation aircraft. That is, not the F-35 or F-22, but somewhere close to the Su-35. And here there is something to think about.



This year, the Korea Aerospace Company (KAI) plans to produce at least 40 KF-21A aircraft, production of the aircraft for the needs of the South Korean Air Force should end by 2026. And in the same year, the South Korean Air Force plans to deploy the first full-fledged unit equipped with these aircraft. And by 2032, the South Caucasus Air Force plans to have at least 120 aircraft of this type in service.

In principle, in terms of equipment, the KF-21A does not have anything out of the ordinary: a radar with AFAR, a decent speed of 1,8M, a very significant flight range of 2 km and a combat payload of 900 kg of bombs and missiles.

But there are also things in the design of an aircraft that should not be overlooked. The aircraft is slightly more than half (65%) South Korean. The airframe, radar, avionics, hydraulics are all Korean. The rest - the engines, their control system, and the weapons control system - are American.

As for weapons, everything is clear: the South Korean Air Force in terms of combat aircraft consists of 100% American equipment: F-5 Tiger II (Korean name KF-5, as it is assembled in South Korea under license), F-16 Fighting Falcon , aka licensed KF-16, F-4 Phantom II, F-15E Strike Eagle.


Naturally, all the weapons on the planes are also American. They are not talking openly about the KF-21A’s armament yet, but if you look at the T-50, a combat training fighter of the South Korean Air Force, which was also made in cooperation with Lockheed Martin, its armament includes AIM-air-to-air missiles. 9 Sidewinder, AIM-120 AMRAAM, air-to-ground AGM-65 Maverick, satellite-guided JDAM bombs.


Well, it’s clear that there’s simply no point in fencing your garden in such a situation. And the KF-21A will also be armed with American bombs and missiles.

And here we will pay a little attention to this airplane, because it makes sense.


The T-50 made its first flight on August 20, 2002. The base was the Samsung KTX-2 training aircraft, which was significantly rebuilt by professionals from the Lockheed-Martin corporation. The result was a two-seat combat training aircraft, a classmate of our Yak-130, although superior to our aircraft in many respects. The T-50 is almost twice as fast (1,4M), can climb 2 km higher on the ceiling, and takes on more combat load. Our aircraft has a longer flight range and a significantly lower cost. Moreover, a very significant one, 15 million dollars versus 25.

The car turned out to be successful, and other countries began to buy it. Local, so to speak: Indonesia, Philippines, Thailand. From far away are Iraq and Poland. Half of the produced T-50s were sold for export, which, I am sure, recouped part of the development and production costs.


That is, in addition to tanks, howitzers, corvettes and boats, South Korea began to export aircraft. Combat ones, too, because Poland then ordered not a training version of the T-50, but an assault version, the so-called FA-50.

And in general, if you look at the reference books, from 2000 to 2021 South Korea increased its arms exports by 178,6%, moving from 31st place in the world to 8th. The top 10 world exporters are serious.

And, as you know, appetite comes with eating. Obviously, having looked at the successes of the Russian-Indian Su-30 program, the Koreans decided to do something similar and created a consortium with Indonesia specifically on the KF-21 topic.


It must be said that Indonesia's fleet of combat aircraft is a rather bizarre mixture of Russian Su-27 and Su-30 of various modifications (5 Su-27 units and 11 Su-30) and American F-16 of various modifications in the amount of 39 units and living out their days F-5F (no more than 5 units). Plus British, Brazilian and South Korean combat training aircraft, which are also listed as light attack aircraft.


And now, after some pressure from the United States in recent years, Indonesia has practically stopped communicating with Russia regarding the Su-30MK2, but for some reason it is also not eager to take American aircraft. And now - such a nod as the joint development of the KF-21, albeit as a junior partner. That is, Indonesia invested money in development, and will receive preferences by plane.

It’s not for nothing that at the presentation in 2022, the KF-21 flew with two flags on its nose: South Korean and Indonesian.


In general, having aircraft in service, spare parts for which do not need to be transported halfway around the world, without fear of sanctions and other troubles, is not bad. But we will return to the issues of regional sales at the end.

So far in 2022, the KF-21 has made its flight, the Korean media has been very supportive of this matter, announcing that the creation of the KF-21 took only six and a half years.

In fact, story KF-21 or KF-X, as the project was called then, was somewhat longer.

In November 2000, South Korean President Kim Dae-jung voiced demands for the creation of a new fighter and the start of mass production by 2015. The F-16 was taken as a model, that is, the new aircraft had to exceed the parameters of the American car.

2 years later, in November 2002, the Joint Chiefs of Staff is developing a long-term plan to develop such a fighter.

year 2009. A study was conducted by order of the Government of South Korea, the purpose of which was an economic analysis of the feasibility of developing a new aircraft. The analysis showed that the development would be economically profitable.

2011-2012. Initial research process and pilot development.

year 2013. The KF-X development plan in detail, including operational capabilities, has been completed and submitted to the Government.

December 2015 DAPA signs a development contract for the KF-X with KAI.

That is, Koreans are just a little bit cunning. Of course, it is unrealistic to develop and build an aircraft in less than seven years. As you can see, a full 13 years passed from the decision to develop the aircraft to the presentation of the full project. Of course, this period could have been greatly reduced, but apparently the Koreans take a long time to harness.

Well, then, in 2020, the assembly of the first prototype began, which was completed in 2021.


The Defense Acquisition Program Administration (DAPA) of the South Korean Ministry of National Defense, which is in charge of all development and procurement for the Ministry of Defense, characterizes the KF-21 as a 4,5 generation fighter, which is a category that is usually used to define new or significantly modernized fighters that have appeared since the 1990s. If in our opinion, then 4+.

Compared to fifth-generation fighters, such aircraft typically lack some key features, such as stealth or thrust-vectoring engines.

The KF-21 was no exception; its General Electric F414-GE-400K engine (installed on the F/A-18 “Super Hornet”) does not have a UHT. And its shape is far from those of the next generation of stealth aircraft.

On the other hand, with the KF-21, South Korea chose a path very different from that followed by manufacturers of fourth-generation fighters such as the Super Hornet, Eurofighter Typhoon or Dassault Rafale, the Russian MiG-35 or Su- 35, which are truly significantly modernized designs from the last century.

The Koreans do not hide that the KF-21 is the beginning of a long process in which, developing in a spiral, the aircraft will acquire new forms, new equipment, and new properties over time.

Accordingly, ongoing work in the future will ultimately result in a version of the KF-21 with more significant stealth characteristics, and in the long term - with internal weapons compartment


But even at the outset, the KF-21A or Block 1 will be equipped with Active Electronically Scanned Array (AESA) and Infrared Search and Track (IRST) radar to detect airborne targets. Next is a gradual path of modernization with the necessary changes to both the airframe design and its contents.

By taking this approach, Seoul appears to have cleverly found a way to avoid the huge costs and lengthy processes involved in developing a true fifth-generation fighter from scratch. At the same time, the basic KF-21 promises to offer at least as much as competing fighters of the same generation, with all the advantages that come from being manufactured in-house.

In addition, South Korea saves a very important resource - time. Considering the difficult foreign policy situation in which the country finds itself, and the lack of its own design school, like aviation powers, creating a fifth-generation fighter all at once is a task that could take much longer than it took to create the KF-21.

And so, more than 20 years and 8,8 trillion won have passed since the decision was made, which in dollar terms also gives a very respectable amount of 6,67 billion dollars.

Even if the subsequent version of Block 2 doesn't live up to being a true fifth-generation stealth fighter, that's not such a big deal. After all, Seoul has already purchased the F-35, which meets these criteria, and for a certain time the country's air force will be equipped to perform any mission.

And thus, if the KF-21 Block 1 version quickly falls into the hands of the ROKAF (South Korean Air Force), the first production KF-21s could replace the aging F-4E Phantom II and F-5E/F Tiger II fighters.

This is a very strong move for the Air Force, which will begin the process of replacing old aircraft with not just new ones, but of a much higher class.


The 2032 milestone is when the country's air force should receive its entire order of 120 KF-21 Block 1 aircraft, and work on the more advanced Block 2 should be in full swing.

By that time, the KF-21 Block 2 training program for ground targets should already be completed. Combining improved stealth with an air-to-ground weapon promises to make the KF-21 a powerful air defense penetration tool against key high-value targets such as North Korea. And if you consider that South Korea has complete order with the production of its attack UAVs and the presence of the F-35, then in general this represents a completely viable concept of action against a neighbor even with a breakthrough of its air defense defense.

And there is confidence that this will really happen. After all, the Koreans were able to overcome the unexpected refusal of the United States to share technology, as a result of which the entire KF-21 program was brought to the brink of failure.

The point is that, according to the original plans, the United States will provide the KF-21 with an AESA radar, an IRST sensor, an electro-optical guidance container and an radio frequency jammer. But something went wrong, and in 2015 the US government revised the supply of these technologies towards refusal. As a result, the South Koreans had to quickly carry out what we call import substitution.

As a result, South Caucasus now has its own developments, which means the possibility of potential export.

The main air-to-air weapons will consist of short-range IRIS-T missiles from the German company Diehl and medium-range Meteor missiles from the European consortium MBDA.


It is obvious that creating from scratch the capacity to produce decent aircraft engines or air-to-air missiles is far from easy, even for such a technically advanced country as South Korea. So it makes sense to outsource these things, especially when the missiles on offer are at least as good as, and maybe even superior to, their American counterparts.

At this stage, with one prototype in the air and five more (of which four are two-seat variants) in active production, it looks like Seoul's decision to take a different route to create the next-generation fighter may be paying off.

But there may be problems here.

The Southeast Asian market is a challenging market. The USA, Russia, and China are present there. And everyone wants to sell their planes. Of course, Chinese aircraft are not the best that can be in service compared to their competitors, but there are not so many rich countries that can afford the Su-35 or F-35.

But South Korea has a chance with those countries that have already bought the T-50. Indonesia, Philippines, Thailand. Moreover, Indonesia generally has a 20% share in the KF-21 project.

True, all of the countries listed do not have luxurious military budgets, but the KF-21 can become a good competitor to American aircraft in terms of price, and Russian aircraft are still being held back on the market by their threats of US sanctions.

However, we should not forget how changeable the political weather can be. Today, yes, Russia has certain problems with the sale of military equipment on the world market, but it is not worth denying that some types of weapons are of greater interest than before the start of the SVO. Considering that Malaysia, Indonesia, and the Philippines have shown genuine interest in purchasing Russian aircraft, a change in the political climate may entail an active return of Russia to the arms market.

Today it is clear that the same combat aircraft are needed by more VKS, but by the time South Korea is ready to make the KF-21 for export, who will guarantee that our Su-35, which has a successful track record, will not enter the market again? combat use and more interesting characteristics in terms of UVT and more powerful engines. We’ll simply keep silent about the set of weapons, because in this regard only the Americans can compare with our aircraft.

And most importantly, in terms of price, the Su-35 is no match for the Joint Strike Fighter program aircraft of all modifications. And in this case, the KF-21 will remain in a very unenviable role as a cheaper, but much less powerful alternative to the F-35 and Su-35. The issue of price is a very difficult issue.


Indonesia, which from the very beginning of the project planned to purchase at least 50 KF-21 fighters, this, in fact, was the point of participating in the project from the very beginning. But for now the country is facing a certain crisis, and the purchase of such a number of aircraft is being postponed. What will happen next is again a question, because Indonesian pilots are well aware of what both the F-16 and Su-30 are. And how Korean aircraft will fit into such a company is a question.

We will wait with interest to see how far the KF-21 goes in realizing its potential, both in ROKAF and in the export market. But this will be a very difficult battle with aircraft that have not been on the market for the first time and have been tested not only by time, but also by combat operations.

    If the logic of the article is told about the very curious Korean KF-21, then on the whole everything was a success. But what does the Su-35 have to do with it? What side is he here? The KF-21 is "semi-stealth" with advanced avionics, like the F-35 at minimum wages. Apart from Indonesia, his export prospects include Poland, Turkey (if the US allows) and the Philippines. In turn, during its career, the Su-35 was delivered to one country - China. And there is a very high probability of delivery to Iran. They can intersect only when the Philippines selects aircraft (or if we dump very heavily with Indonesia). But this is practically a fantasy, since we will be allowed into the market either in the event of a complete victory in Ukraine, or an equally complete defeat. Since we are now far from both options, competition between these aircraft is extremely unlikely.

        I wrote it carefully, since the Russian Federation never officially confirmed the existence and specifics of the contract. Moreover, she did not confirm any numbers. So to speak. in fact, and according to Iranian agencies, you are right.
        I hope the contract will be completed in full, and it will not work out both with Egypt (the planes destined for which went to Iran) and with Indonesia. There is every chance of this, since there are actually no other suppliers for Iran (the PRC will not get involved with this).

      I don’t really understand why Indonesia and the Philippines got involved with this. Because given their geography, they need an attack aircraft with maximum flight range, loitering time, and capable of carrying heavy anti-ship missiles, preferably more than one. They have only one real enemy - the People's Republic of China. And conflict is possible - because of the islands. That is, far away and over the sea. And here - the Su-35 is almost ideal for them.. Another thing is that on the Chinese side it will obviously be almost the same..

        Indonesia wanted to buy the Su-35, which would be a logical development of their Su-27-Su-30 line. But, alas, sanctions. Now the likelihood of returning to their market is negligible.
        The Philippines has always bought American. Potentially, yes, they could have bought the Su-35. But now they cannot do this.
        Their interest in the KF-21 is logical, the F-35 is expensive and it’s not a fact that they will even sell it. The KF-21 with high situational awareness and low RCS can be very good for overcoming air defense and ground strikes (in the block 2 version). With the Su-35 they occupy different “ecological niches” and could well be combined.

    As usual, there are a lot of letters and little specifics. This plane is just drawn based on the 5th generation. Well, respect to the Koreans for almost making the siogli themselves and putting the plane into production.
    You don’t even have to consider the option that the T-50s will end up in Ukraine. They will burn very quickly. This is a "stormtrooper" only against aborigines in the jungle.
    Comparing the Korean T-50 with the Yak-130 is incorrect. The plane is slightly better than the L-39 or a modern multi-role combat trainer and fighter-bomber. We can discuss this topic for a long time, but, by and large, it will come down to the idea that I expressed in the previous sentence.
    There is a very important nuance here. The farther we go, the DPRK is falling further and further behind South Korea in terms of aviation. And their only salvation is the purchase of modern aircraft from Russia. It is no coincidence that Kim Jong-un came to us

    But things aren’t going well there...the idea of ​​a reunion was finally torn apart the other day.

    And a strike (by analogy with air defense) can happen not only at airfields,
    but also for the enterprises of the military-industrial complex of the South Caucasus.
    And these risks when purchasing equipment from the UK are bought by Indonesia, Poland, etc.

    Unlike Russian technology. There are no future risks in purchasing the Yak-130/Su-30.

    Of course, that breakthrough in the development and production of various types of weapons, whether air, sea, or land, could not have happened in South Korea without the permission and support of the United States, but they took advantage of this chance very well. And personally, I think that in these matters they are already ahead of India.
    As for the described KF-21, it is apparently worth noting its external similarity with the Chinese J-31 and the Japanese Mitsubishi X-2 Shinshin. I think that there will be a struggle between them in the markets of third countries. For those for whom the F-35 will be too expensive or “inconvenient”, politically.
    Considering that this “Korean”, after modernization, will clearly go into the “fifth” generation, on our side its competitor will not be the well-deserved Su-35, but the promising Su-75

    And what? Until they have their own engine, it’s all fiction. At any moment, the United States can slam any sales of this aircraft. Or even production in general. And they will do it - if the Koreans even once try to cross their path in the arms markets.

    And YUK won’t have an engine for a very long time. Even the PRC, which has incomparable resources and apparently has access to some Soviet technologies, is still only at the beginning of its journey. Somehow they can’t come up with anything convincing. What can we say about the Koreans...

        The Chinese also have no problems with mechanical engineering. There is no engine yet. In general, a modern jet engine is perhaps one of the peaks of technical development. Along with nuclear power plants and chips. Because for their production and, most importantly, development, you need to have behind you very strong scientific and technological schools of your own in a bunch of areas. Which take decades to develop. And this process cannot be replaced by any money or licensed assemblies... At the moment, only we, thanks to the great Soviet heritage, and the conditional West can do this - because there you can’t figure out which company belongs to which country. All.

    Yeah.

    Before us is a twin-engine aircraft with an F414. That is, an F-18 refinished with plastic to look like stealth. His main problem at the moment is AFAR. If they still persuade the Americans to use a phantom ai or install one of the latest Europeans, then there is nothing to catch the Su-35. There is nothing for a Korean to catch in a cannon fight - however, I’m not sure that the Koreans are into a cannon fight.

    Well, the Su-35 has nothing to catch anyway. The Korean is an aircraft of the NATO “ecosystem”. If a country follows the Anglo-Saxon course, so to speak, then it no longer considers weapons standards compatible with NATO. And vice versa.

        Only the Korean is 4 tons lighter than the Superhornet with the same engines. It looks like a move towards “non-afterburning supersonic”.

        “Non-afterburning supersonic”, “with the same engines”, does not depend on the mass of the aircraft.

          Same engine.
          Thanks to the new General Electric F414 engine with a thrust of 6 kgf (500 kgf in afterburner), the fighter will be able to perform non-afterburning supersonic flight at speeds up to M = 10.

          During testing of the 39-7 aircraft, its ability to perform supersonic cruising flight with Mach number = 1,2 in non-afterburning engine operation was demonstrated.

    Naturally, all the weapons on the planes are also American. They are not talking openly about the armament of the KF-21A yet.

    The armament of the KAI KF-21 Boramae is not something that they talk openly about, they even report specific contracts (for example - https://www.mbda-systems.com/press-releases/south-korea-to-integrate-mbdas-meteor -missile-onto-kf-x-fighter-aircraft/). And the aircraft’s armament is international, as they say today - from the world’s best manufacturers.
    If we take air-to-air missiles, these are the American AIM-120 AMRAAM, AIM-9X Sidewinder, ASRAAM, the European MBDA Meteor from the transnational European consortium MBDA and the German IRIS-T.
    The arsenal of air-to-ground missiles looks exactly the same - the American AGM-65 Maverick, the German-Swedish Taurus KEPD 350, in the future MBDA Brimstone, SPEAR 3. In addition, the Koreans plan to develop their own Taurus-level cruise missile by 2028. But ordinary bombs, UAB and KAB are really all American.

    That is, Koreans are just a little bit cunning. Of course, it is unrealistic to develop and build an aircraft in less than seven years. As you can see, a full 13 years passed from the decision to develop the aircraft to the presentation of the full project.

    Koreans are not lying at all. It’s just that in 13 years the Koreans have developed five projects. The first four are KAI KFX-E, ADD C103, ADD/KAI C105, ADD/KAI C109. Then, having assessed the advantages and disadvantages, on the basis of the ADD C103 project in 2015 they began to create the KAI KF-21 Boramae.

    The Southeast Asian market is a challenging market. The USA, Russia, and China are present there. And everyone wants to sell their planes. Of course, Chinese aircraft are not the best that can be in service compared to their competitors, but there are not so many rich countries that can afford the Su-35 or F-35.


    I doubt that the export of Chinese aircraft has any serious prospects. China pathologically loves to embed “undocumented functions” into electronics; there is a very high probability of spyware in military equipment; is it really acceptable when purchasing an aircraft worth tens of millions of dollars?
    China's share in arms exports decreased from 6.3% (2013-2017) to 5.2% (2018-2022), South Korea increased from 1.3 to 2.4%. https://www.sipri.org/sites/default/files/2023-03/2303_at_fact_sheet_2022_v2.pdf

    After WW2, a black cat ran between the Koreans (well, like we do with the dancers) and the country was divided. They developed in completely different directions. Today we have: South Korea with a population of 50 million people, a world leader in shipbuilding, electronics, very good in the arms business, etc. S. Korea itself has created nuclear weapons and ballistic missiles, textiles at the level, weapons for the poor, etc. Population 25 million
    Now let's remember that all this is in a very small area and there are not very many natural resources. What if they were a single state? Japan, China, and the Russian Federation would be breathing deeply. Koreans are certainly impudent and arrogant, but God certainly did not offend them...

      There were two black cats: Stalin and Roosevelt. According to the agreement between the USA and the USSR, the surrender of Japanese troops north of the 38th parallel was to be accepted by Soviet troops, and American troops to the south. Then foreign troops had to leave Korean territory because Korea was not a belligerent state, but was forcibly incorporated into Japan in the early 20th century. But already in 1946, the United States began planning a war against the USSR using nuclear weapons.

    World experts evaluate the KF-21A as a 4++ generation aircraft. That is, not the F-35 or F-22, but somewhere close to the Su-35. And here there is something to think about.

    The Su-35 is the pinnacle of modernization of the Su-27. And the KF-21A is an aircraft whose modernization capabilities have not yet been used.
    The airframe, radar, avionics, hydraulics are all Korean.

    According to initial plans, the United States will provide the KF-21 with an AESA radar, an IRST sensor, an electro-optical targeting pod, and an RF jammer.

    The Koreans wanted to buy electronics from the F-35. The Americans did not agree. But nevertheless, many companies participated in the development of the aircraft in one way or another, including Lockheed Martin, Israeli Elta, Saab, Italian Leonardo, and other English, Spanish and American companies.
    but, if you look at the T-50

    It’s not entirely clear why the T-50 is a completely different aircraft.
    two-seat combat training aircraft, a classmate of our Yak-130

    Yeah, classmate. One is supersonic, the other is not.
    Poland then ordered not a training version of the T-50, but an assault version, the so-called FA-50.

    Poland has shown interest in the KF-21 and would like to enter the project at the Block-2 development stage; the Koreans have no fundamental objections.
    Of course, this period could be greatly reduced

    The Koreans were looking for co-investors for development and production. As a result, the Korean government's share of expenditure was only 60 percent.
    The KF-21 was no exception; its General Electric F414-GE-400K engine (installed on the F/A-18 “Super Hornet”) does not have a UHT. And its shape is far from those of the next generation of stealth aircraft.

    Not that far. The hand of Lockheed Martin is visible. There are not enough internal compartments, but there is a fundamental possibility of installing them. Due to the development of rockets and electronics, UHT is no longer considered a mandatory feature of fifth-generation aircraft.
    "Super Hornet", Eurofighter "Typhoon" or Dassault "Rafale", Russian MiG-35 or Su-35, which are truly significantly modernized designs from the last century.
