What's new

KFX/IFX News and Development

Let's end this pipe dream. It seems clear that Jokowi isn't interested in paying the contribution towards the program and the Indonesian government is actively looking for alternative systems. (by the way, I do think F-16 may suit Indonesia better than KF-X/IF-X) Cancelling the submarine orders from DSME would further sour the relationship between two nations.

It doesn't matter how determined & mentally prepared the nation is for the project when they are not actually paying for the program. We can talk about how the project benefits Indonesia in both short-term and long-term, but the bottom line is that Indonesia won't receive the prototype nor be able to produce KF-X/IF-X locally as they simply are not paying for it.

I am pretty sure you are aware that the project can't wait for the next presidential election in Indonesia. It will progress and Indonesia would be denied to access to the final product unless they finally decide to pay up the full amount.

I can say this year and next year we have abundant of money coming from pandemic stimulus budget. Until December we just use around 65 % out of 49 billion USD economic stimulus budget intended for 2020 spending.

I am quite optimist government will pay our due and next payment (plus set aside money to complete our financial contribution) next year inshaAllah. Jokowi is stingy, he even hasnt paid government debt to our own state owned companies for years. The total debt is 115 trillion Rupiah or in USD is around 10 billion USD.

I just heard government has paid it after they borrow huge money from financial market (bond market) to finance the economic stimulus program. Our SOE minister even need to say it in public around July this year to pressure Jokowi to pay government debt to our state owned companies which become our main force in financing and building our massive infrastructure program along his own period

The reason Korean need to build their own fighter than just relying on US fighters. These coming from Korean Air Force ex pilot/General. One main reason is that it will be cheaper and easier to maintain our own fighter. In the time of war, this is very crucial. Some time he said Korean must delay the maintenance for about six month or even up to one year due to their dependency on US manufacturer.

Indonesian Aerospace official also said previously in other media that Indonesia will be much easier to upgrade the plane if KFX/IFX become our back bone fighter and he said this will give some sort of adventage for our Air Force that can increase our deterrent capability.

Indonesia equips frigates, corvette with stealth radars
Ridzwan Rahmat, Singapore
- IHS Jane's Defence Weekly
14 April 2014

The Indonesian Navy (Tentara Nasional Indonesia - Angkatan Laut: TNI-AL) will equip a total of four Ahmad Yani (Van Speijk)-class guided missile frigates and one Kapitan Pattimura (Parchim I)-class corvette with low-probability-of-intercept (LPI) naval radars.

The radars will be built by Indonesian naval sensor manufacturer PT Infra RCS, company officials told [i>IHS Jane's on 11 April.

The company describes its equipment, the IRCS LPI Radar, as a stealthy sea-based X-band (SBX) radar with frequency modulated continuous wave technology.

"It has a maximum power output of only 10 W, making it quiet and virtually invisible to radar warning receivers on enemy vessels", said Prihatno Susanto, Technical Advisor for the company. "This allows our warships to detect hostile surface combatants without being discovered".

The IRCS LPI Radar has an effective range of 24 n miles and is equipped with tracking software known as Maritime Tracking Aid that allows for automatic radar plotting aid functionality. The system's antenna rotates at 20 rpm and has a gain of about 30dB.

The radar is available as a stand-alone system but can also be integrated with a vessel's electronic chart display and information system (IRCS) and combat management system.

The vessels now equipped with the radar are the guided missile frigates KRI Ahmad Yani and KRI Abdul Halim Perdanakusuma. Both began upgrade works in December 2013. Undergoing the equipment fixture currently are similar vessels in class KRI Yos Sudarso , KRI Oswald Siahaan and the Kapitan Pattimura-class corvette KRI Sultan Taha .

Besides LPI naval radars, the company has also won a contract to equip Oswald Siahaan and Yos Sudarso with naval electronic support measures (ESM) systems that can detect electromagnetic emissions from electronic devices on enemy ships such as radar, communications equipment, jammers and missile targeting systems.

"The IRCS ESM has electronic intelligence (ELINT) capabilities that can pick up signals emitted by hostile warships from up to 90 n miles away via a passive radar", said Susanto. "Once these electromagnetic emissions are detected, a computer software that comes with the system will be able to identify, classify and pin-point the exact location of the source for commanders to take action."
The company has indicated that it is currently embarking on an effort to market both systems internationally.

[Contribution] In celebration of first assembly of KF-X airframe
By Korea Herald Published : Sep 20, 2020 - 16:54
Updated : Sep 25, 2020 - 11:44

Bradley Leland
Bradley Leland is the Lockheed Martin Program Director for the KF-X Program as part of F-35 offset. He has an extensive background in fighter aircraft development, including the F-22, T-50, and F-35 Programs. He has been supporting Korea Aerospace Industries since the beginning of the KF-X program in 2015. -- Ed.

Nearly five years ago, the KF-X Program began. It began with a vision, a vision built upon a 30-year commitment to successfully develop an aerospace industry in Korea.

The KF-X vision was the next step, and the pinnacle of a world-class aerospace industry. The KF-X is an outstanding, indigenous, highly advanced fighter aircraft.

ad
Five years ago, the many professionals at Korea Aerospace Industries, the Defense Acquisition Program Administration, and the Republic of Korea’s Air Force began working hard to mature that vision, to turn the vision into reality.

Sept. 3 was a major milestone. On this day, the forward fuselage, center fuselage, and aft fuselage assemblies all came together to make a single airframe. We now have the complete structure of the first KF-X aircraft.

But what you see is not just an airframe structure. It is so much more. It is the result of a long and complex journey, for there is a long distance between a vision and an airframe.

ad
Korea assembled a leadership team, and then embarked on that difficult journey at the end of 2015. They first turned the vision into a set of requirements, which is never easy. But from those requirements they developed a design. And that design was analyzed, refined, and optimized until it could meet those strict requirements in 2019.

But the process had only begun, for next they had to engineer each part -- over 10,000 parts. And each part needed a manufacturing drawing. Each part had to be fabricated precisely. Each part had to be assembled perfectly, and in proper order. For more than two years those parts have been fabricated by fine craftsmen across Korea.

As those parts were completed, assembly began. It began with small sub-assemblies, that led to large assemblies, and finally to aircraft sections by the skilled manufacturing workers at Korea Aerospace Industries.

On Sept. 3, KF-X became a complete airframe, but it represents so much more. It represents hundreds of expert engineers and millions of man-hours of design and analysis. This airframe reflects hundreds of small companies of skilled craftsman across Korea. It reflects the dream and commitment of ROKAF, the leadership of DAPA, the diligence of KAI technicians, and the courage of KAI management. Today, all of Korea can be proud.

I have learned to never underestimate the power of the Korean people. Many thousands of people working together, working toward one common vision.

Now you can see the vision is becoming reality. Soon the systems will be installed and tested. Soon the airplane will come to life with electrical power. Soon it will move on its own wheels, using its own jet engines.

And soon this airframe will become an airplane, and it will fly. And as you can already see, she will be beautiful.

During N 219 certification process ceremony in 28 December 2020, it is said by one of our former Airforce commander, Chappy Hakim, that newer generation engineers working in Dirgantara Indonesia (DI), which come from millennial generation, are quite enthusiast working because there are a new civil aircarft project, N 219, and also a military project, KFX/IFX program, going on. Those projects are both very good to improve Indonesian young designers/engineers knowledge/expertise particularly because they are also working with senior engineers from DI and also KAI and Lockheed Martin.
 
.
I put this 2016 information from Indonesia Defense Ministry official website to understand about the project further and about Indonesian contribution on the program. This is also important since there is disinformation going on to jeopardize the cooperation between the two countries.

In 2015 Korea and Indonesia has reached the agreement about work sharing and other so the information being put here is still up to date since the information is based on the 2015 deal that start the second phase of KFX/IFX program which is manufacturing phase after first phase, technology development phase, that started in 2011.

Korea Indonesia KFX / IFX Combat Aircraft Project
Monday, May 2, 2016

The development project of a 4.5 generation advanced fighter aircraft called KFX / IFX, which is being carried out by South Korea and Indonesia, has officially started in recent months. Indonesia, which bears 20% of the development fund, has also prepared infrastructure and human resources to support the success of this biggest Indonesian military project. Then what has Indonesia prepared?

The first thing that has been prepared by the Indonesian government is to build facilities to support this project in the future. The facilities under construction are a special hangar for the composing hangar facility, titanium hangar, production hangar, and hangar for the final assembly of this fighter aircraft in Bandung, West Java. This particular hangar is located in the area of PT Dirgantara Indonesia, and is almost complete.

In this special facility for the KFX / IFX project, it will be used by the Indonesian side for the purposes of this project. Indonesia itself is reportedly going to get a share to make a number of important components of this sophisticated fighter. Among them are the wing, tail and wing reinforcement components of this fighter.

In addition, it is also reported that in this facility, one of the IFX fighter prototypes will also be built which will become part of Indonesia. As we all know that in this KFX / IFX project, 6 prototypes will be built which will undergo a series of flight tests. One of these 6 prototypes will belong to Indonesia. Apart from the 6 prototypes, there will be 2 other prototypes to be built which will not be tested but will undergo a series of aircraft structural tests. The KFX / IFX fighter prototype to be produced in Indonesia is the fifth prototype, and will be a fully carried out test flight aircraft in Indonesia.

Design KFX / IFX C-103 Conventional Wing Dual Engine

Not only preparing for infrastructure, Indonesia has also started preparing my human resources since a few years ago to support this modern fighter development project. The Indonesian government and PT Dirgantara Indonesia are reported to have prepared around 200 to 300 experts to be involved in this mega project of the Indonesian military . However, a large number of experts will come to South Korea gradually over the next 10 years. However, there are also experts who will be involved for 10 years from the start.

Some of the experts from Indonesia themselves will be sent to school abroad, especially to European countries to sharpen their knowledge, before being directly involved in this project. The additional knowledge they get from European countries is expected to be of additional positive value for the development of Indonesian combat aircraft in the future.

The number of Indonesian experts involved in the second phase, known as the Engineering and Manufacturing Development (EMD) phase, was far more than the first phase (Technical Development Phase), which only amounted to 52 at that time. The first phase (Technical Development Phase) itself lasted 18 months from 2011 to 2012. Meanwhile, the second phase (EMD) will last for 10 years, involving 200-300 Indonesian experts.

Not only aerospace experts, the Indonesian military has also prepared several pilots from the Indonesian Air Force as test pilots for this fighter aircraft later. It is reported that 5 test pilots have been prepared for this KFX / IFX fighter later. The five pilots are reported to have qualified and had sufficient flight hours with the KT-1B Wongbee and T-50i Golden Eagle trainers.

Not only that, the five candidates for the KFX / IFX fighter pilot test have also been specially assigned to S1 Aviation Engineering - Bandung Institute of Technology (ITB). This is done so that the five prospective test pilots are also equipped with adequate aviation knowledge in addition to the ability to be fighter pilots.

This considerable preparation is expected to be a step towards the success of the KFX / IFX fighter aircraft development project which in the future is expected to become the foundation of the TNI's defense equipment, especially for Indonesian combat aircraft in the future. Although this fighter plane is not purely an Indonesian-made fighter, Indonesia has high hopes for the success of this project.

But of course all these preparations do not guarantee that this project will run smoothly and smoothly. Of course there will be many obstacles and obstacles that will still be faced, but at least all the preparations that have been carried out are a good first step. We cannot confirm the success or failure of this mega project of the Indonesian military and only time will tell.

There is disinformation going on in Indonesian circle as if Indonesia can only get profit from the sales of IFX which is not true. Some people dont understand how business operates, if we invest 20 % in a business of course we will get 20 % profit from all the sales, regardless it is IFX or KFX, and Indonesia doesnt only contribute on the cost but also work force and skills where the design development alone requires 114 Indonesian experience engineers/designers, I said experience because KAI only want engineers whose age is above 35 ( coming from Deputy Defense Minister statement in CNBC Indonesia June/July 2019)

Other disinformation said that Indonesia only produce some components for all KFX/IFX without any assembling/integration work which is not true since all of IFX will be assembled in Indonesia Aerospace and the components being made is for all KFX/IFX. I believe the possibility for KFX (not intended for Indonesia Aerospace) to be assembled in Indonesia Aerospace if the demand is quite high is also very possible, just look on Turkey where they still produce F35 components despite being kick out from the program, due to F35 high sales.

Current Indonesian government ask for export right, so what does it means ? It means Indonesia will be able to do assembling/integrating work for KFX that will be sold outside, not only for IFX as current deal said. So it talks about more Indonesian Aerospace contribution on the manufacturing and it is also to make the program sounds more indigenous like CN 235 program where Indonesia Aerospace share 50 % of the development cost. Indonesia will still get 20 % profit from all KFX/IFX sales regardless we get export right or not.

This is all coming from genuine information from Indonesia defense ministry website that I posted in above post and about 114 designers during design development comes from KAI official that is cited by Jane Defense publication. I hope Indonesian out there relies the information about the program from genuine source and respectable media like Kompas/Tempo/Angkasa/Jane Defense and in some extend CNN Indonesia if they have quotes from official (not the reporter narrative/analysis).

For those Alay generation who flood South Korean Facebook, I hope they write their opinion politely and do research first before commenting there. Some Indonesian act like girl who believe on rumors or every thing said by private Youtube channel with all of the sensation there. In order to see the program in a fair judgement we should look on the pro and contra of the program and it should be from people who knows the program and from respectable media as well.

Even politician comment like ex deputy of defense ministry official should not be swallowed just that, we need to be critical as they may get approached by foreign OEM to make Indonesia leave KFX/IFX program and buy that OEM fighter or other thing like his lack of understanding about technology development or lack of vision and others.

I think many contra opinion (coming from politician/private Youtube narrative/reporter interpretation) has been known already so I need to put the pro argument coming from Indonesian who were inside the KFX/IFX program during SBY admnistration so he knows better than YT abal abal with some dis-information they have created regarding the program or some green politician that just come to power or politician with has vested of interest.

Marsdya (Pur) Eris Herryanto Bicara Soal KFX/IFX: Korea Itu Tulus, Mereka Mau Ngasih Apapun ke Kita

Angkasa.news - Jika angkasa.news tidak keliru, Marsdya (Pur) Eris Herryanto adalah salah satu dari sedikit purnawirawan perwira tinggi TNI yang sangat fasih menjelaskan tentang program pesawat tempur nasional IFX (Indonesian Fighter).

IFX dan KFX adalah proyek pengembangan pesawat tempur generasi 4,5 yang digawangi Korea Selatan. Pada 2009, Indonesia menyatakan minat untuk terlibat, yang ditandai dengan penandatangan letter of intent (LoI).

Proyek ini dinamakan Korean Fighter Experimental (KFX) dan Indonesian Fighter Experimental (IFX). Pesawat akan diproduksi sebanyak 168 unit dengan rincian 120 unit untuk Korsel dan Indonesia diperkirakan 48 unit. Produksi massal rencananya dimulai 2026.

Pada 15 Juli 2010, pemerintah Indonesia setuju untuk mendanai 20% proyek KFX dengan imbalan sekitar 50 pesawat untuk TNI AU. September 2010, Indonesia mengirimkan tim ahli hukum dan ahli penerbangan ke Korea Selatan untuk membahas masalah hak cipta.

Di Indonesia sendiri, pemberitaan terkait program IFX naik turun ibarat ombak di laut. Ada yang bilang tetap jalan, terseok-seok, bahkan yang ekstrem bilang sudah berhenti.

Bertanyalah kepada yang paham, itu kata orang bijak. Untuk itu Angkasa pun menemui Marsdya (Pur) Eris Herryanto di lapangan terbang Pusdirga, Cibubur. Penerbang F-5E/F Tiger II dan F-16 Fighting Falcon ini sudah terlibat proyek KFX/IFX sejak awal.

Dengan jabatannya sebagai Dirjen Sarana Pertahanan Kemenhan (2007-2009), Irjen Kemenhan (2010), dan Sekjen Kemenhan (2010-2013), menjadikannya paham betul sejatinya program IFX.

Usai mendaratkan pesawat aerobatik Pitts S-2C yang rutin diterbangkannya setiap akhir minggu di Cibubur, Marsdya Eris bicara banyak tentang program KFX/IFX.

Publik selalu bertanya, apakah program IFX masih jalan?

Masih jalan, karena kita masih mengikutsertakan 72 ahli sesuai bidangnya. Misalkan bidang aerodinamika, ya mereka, yang lain belum. Banyak sekali tenaga ahli yang terlibat dari kita untuk KFX/IFX.

Program ini terkesan tidak berjalan lancar, apakah tidak ‘dikunci’ saja sebagai program nasional?

Kalau ditanya bisa atau tidak, saja jawab bisa. Masalahnya pemimpin harus diberi masukan, apa manfaatnya untuk kita di kemudian hari. Karena ada yang berpikiran Indonesia itu teknologinya belum advanced, jadi kenapa ambisi memiliki pesawat dengan teknologi canggih. Kenapa tidak beli saja, nggak susah-susah. Lalu ada ahli yang bilang, saya sudah sekolah tinggi-tinggi S3 di luar negeri, kalau tidak diberi mainan untuk apa saya sekolah. Jadi harus ada program yang disepakati bersama. Jangan semua bagian punya maunya sendiri-sendiri. Pemimpin harus bilang bisa, dengan masukan yang benar.

Apakah komitmen IFX tidak fixed dari awal?

Karena orangnya ganti-ganti. Programnya sudah fixed, tapi kalau pejabatnya baru dan dia tidak mengerti lalu tanya-tanya dan tidak dapat penjelasan, sampai ada yang punya keinginan lain, jadinya berubah. Contohnya radio. TNI butuh radio yang memiliki interoperability darat, laut, dan udara. Oleh karena itu supaya tidak tergantung, bikin sendiri. Ok, industri bilang bisa asal diberi kesempatan. Tetapi komitmennya harus terus, karena industri investasi di situ sehingga butuh long term. Tiba-tiba ada pejabat bilang, kok radionya begini, beli saja dari luar. Itu yang kita hadapi sejak lama.

Apakah dengan kondisi seperti ini, IFX masih jauh dari harapan?

Tidak jauh sih, tinggal bilang full support, masih ngejar. Kita terlambat 1-2 tahun saja, jadi masih bisa ngejar.

Bisa dijelaskan keuntungan yang akan diraih Indonesia jika menguasai teknologi pesawat tempur?

Saya sering bilang, Indonesia tahun 2035 akan kekurangan sumber daya alam yang kita ekspor. Apakah batu bara, nikel, minyak dll. Menurut Pak Jokowi sudah habis semuanya. Kalau sudah habis, lalu apa yang bisa kita ekspor. Satu-satunya ya teknologi. Kalau kita mau ekspor teknologi, mulai dari sekarang. Kalau tidak, bagaimana kita menguasai teknologi di tahun 2035.

Jangan underestimate orang Indonesia, pintar-pintar kok. Di PTDI itu banyak ahli kedirgantaraan. Saya tanya mereka, gaji tidak masalah buat mereka. Bagi mereka, mainannya mana. Jadi pemimpin harus tahu itu semua bahwa mereka siap mengerjakan.

Mungkin Indonesia berat memenuhi komitmen 20% karena masalah keuangan?

Kita hanya memberikan kontribusi satu tahun Rp 2,1 triliun untuk KFX/IFX. Anggaran belanja kita 2.000 triliun, 2 triliun dari 2.000 triliun hanya 0,01 persen. Tetapi ini akan menjadi backbone ekspor setelah 2035 yang nilainya tidak sedikit.

Anggap saja satu pesawat dihargai 75 juta dolar AS, itu 20 persen dari nilainya sudah ada di Indonesia. Kalau satu tahun kita bisa buat IFX sebanyak 30 unit, berarti 30 x 75 x 20%, berapa perputaran ekonomi di Indonesia. Itu memang nanti kalau jalan, dan kondisinya ideal. Termasuk marketing.

Saya berpendapat banyak nilai positif bisa kita dapat jika program ini jalan.

Apakah perlu forum untuk mengangkat kembali isu ini?


Tidak salah, tapi sekarang kita harapkan siapa. Pemerintah yang utama, yaitu Kementerian Pertahanan. Kita kan sedang development jadi perlu komitmen pemerintah, TNI AU perlu terus mendorong. Leading sector-nya ya Kemenhan.

Kalau saya melihatnya dari segi apapun, program KFX/IFX menguntungkan. Dari segi keamanan, ekonomi, SDM. Zaman Pak Habibie kirim orang belajar ke luar negeri, mereka butuh mainan. Kita punya banyak orang seperti ini.

Mereka tidak cari pendapatan besar kok di luar negeri. Mereka bilang, kasih mereka rumah di Indonesia, gaji secukupnya, saya bangun teknologinya.

Jadi siapa orangnya sekarang, saya tidak tahu. Nanti saya dibilang sok tahu he he he. Tidak ada yang tidak mungkin untuk kepentingan bangsa.

Bagaimana soal teknologi AS di dalam pesawat, apakah akan jadi ganjalan?

Kita kerja sama dengan Korea, mereka bilang akan kasih semuanya ke Indonesia. Indonesia tidak perlu khawatirnya, katanya. Saat ini ada empat teknologi yang belum dikuasai Korea. Tapi mereka tidak bilang, karena mereka sedang dan sudah lakukan R&D, jadi saya tahu sudah dikuasai.

Korea sebetulnya sudah tidak tergantung kepada AS. Namun mereka tidak mau begitu, karena tetap menjaga hubungan. Jadi kalau terjadi sesuatu dalam hubungan dengan Indonesia, Korea yang akan bilang bahwa mereka berteman dengan Indonesia. Korea butuh Indonesia, hanya kadang kita curigaan kepada orang.

Kalau kita diskusi dengan mereka, pahami pemikiran mereka. Mereka diikat UU yang ketat. Kalau melanggar UU seperti korupsi, ampun, hukumannya berat. Mereka sangat takut. Jadi pahami mereka. Mereka all out. Memang curiga itu boleh karena kita sama-sama punya kepentingan dan kita tidak bisa memaksakan kepentingan kita kepada mereka. Tapi mereka punya teknologinya.

Seperti soal kapal selam, Korea peroleh ilmunya dari Jerman dan tekonologinya dikasih ke kita, Jerman nggak protes. Karena apa, sudah dimodifikasi seluruhnya oleh Korea dan sudah dikuasai karena R&D-nya bagus. Walaupun disebut U-209 tapi tidak diprotes Jerman.

Demikian pula pesawat. Saya tahu 129 teknologi yang mereka punya sudah dikuasai. Hanya dalam pembuatan ini (KFX/IFX) Korea minta support.

Jadi kita ikuti saja, jangan kita belum menguasai sesuatu tapi sudah kemaki (sok-sokan). Saya ingat cerita Angling Dharma, yang bisa jadi orang digdaya karena belajar sama orang. Disuruh angkut rumput pun dia kerjakan asal ilmunya diberikan. Kata orang Jawa, ngawulo. Tapi ini kan tidak, belum apa-apa kita sudah kemaki.

Jadi, bagaimana sebaiknya kita menyikapi kerja sama dengan Korea?

Korea beda dengan China. Kalau China melakukan reverse engineering. Mereka beli lalu bongkar dan berani (bongkar) meski dilarang AS. Lalu di-reverse. Jadi polanya beda dengan Korea.

Soal kapal selam, saya diceritakan sejarahnya. Orang Korea pertama yang mempelajari kapal selam ke Jerman, namanya Admiral An. Di Jerman, semua orang Korea yang belajar dianggap buruh, itu tahun 1980 selama 20 tahun. Semua mulai dari bawah, mereka pelajari dan sekarang mereka kuasai dan bisa bikin sendiri. Orang Korea berbakti kepada negaranya sangat tinggi.

Perusahaan penerbangan mereka mulai 1980, dan sekarang kita beli T-50 dari mereka. Tapi kenapa kita berhenti ketika Pak Nurtanio sudah memulai dulu 1946. Apa yang dilakukan Pak Habibie juga diubah semua dan kita failed sejak krismon. Korea tidak begitu.

Pemerintahnya support penuh. Saya yakin tahun 2030-45, Korea menguasai semua teknologi.

Beberapa waktu lalu saya ikut paparan dari Litbang Kemenhan Korea, yang tidak pernah mereka sampaikan di negara lain. Saya minta kopinya tapi tidak boleh karena sangat rahasia.

Artinya mereka punya ketulusan kerja sama dengan kita. Semua kemampuan mereka sudah riset, semua platform mereka punya. Seperti tank K2 Black Panther buatan Korea, canggih sekali.

Dari presentasi itu saya tahu bahwa semua aspek pertempuran masa depan, akan mereka kuasai. Itu dari Litbang militer Korea yang sarjana S-3 nya kalau tidak salah 2.000 orang.

Saya merasa kerja sama dengan Korea itu tulus, harus kita tangkap. Mereka mau ngasih apapun kepada kita.

Indeed Indonesian aerospace engineers are very needed by the KFX/IFX program:

[Herald Interview] With KF-X, S. Korea eyes foothold in global fighter jet market

Chief engineer talks about challenges and rewards of next-generation military aircraft project ahead of prototype unveiling


By Choi Si-young

Published : Oct 22, 2020 - 18:13

The chief engineer discussed the shortcomings he faces as well, saying his team still needs a pool of experts familiar with aerospace technologies.

“We have about 1,300 engineers on the project, but they include those with expertise in shipbuilding and not aerospace,” Lee said, maintaining that for the next five years of jet tests, his team would need more veteran aerospace engineers to pinpoint every glitch in jet performance.

Skilled professionals come first in the high-end industries like the aerospace sector, where precision is a top priority. The fact that KAI is in Sacheon, far away from Seoul, doesn’t help in its efforts to attract and retain top-quality talent, he said.

More on the interview can be check on this link

Number of Indonesian engineers (designers) as of July 2019


"Despite such a delay in payment, the Indonesian side has continued to send its researchers to South Korea to take part in the development process," Rep. Kim Joong-ro of the minor opposition Bareunmirae Party said during a parliamentary audit into the administration, voicing concern about technology leaks.

As of July, 114 Indonesian engineers were sent to South Korea to work with Korea Aerospace Industries Co. (KAI), the country's sole aircraft manufacturer, to design and make a prototype of the fighter, according to a DAPA official.

The history of KFX/IFX Program

2009. MOU between Korea and Indonesia signed
2010. Contract between Korea and Indonesia to develop KFX/IFX fighter is signed.
(I will post Indonesian Presidential Decree about the program that talk about the MOU and Contract later)

2011. The start of Joint R&D

Joint R&D design set up.

52 Indonesian aerospace expert was sent. At that time Korea is represented by ADD and Indonesia with Indonesian Aerospace and Bandung Insitute of Technology. One of the result is C103 design that become the base of final C 109 design.

SACHEON, South Gyeongsang Province ― South Korea is set to roll out the first prototype of its indigenously developed next-generation fighter jet, widely known as the Korean Fighter eXperimental (KF-X) aircraft, late next month.

A total of six prototypes are in the final stages of assembly at the Korean Aerospace Industries (KAI) headquarters in Sacheon, Gyeongsang Province. Test flights will be carried out next year, following ground testing after the April roll-out.

Industry officials expressed expectations that the KF-X would not only help accelerate domestic production of fighter jet parts but also bring about a considerable economic effect, creating jobs for about 110,000 people during the full development period planned through 2028. Since the KAI embarked on the KF-X development project in 2016 after winning the contract from the government the previous year, the project has created jobs for more than 10,000 people as of 2020, according to the company.

Officials also expressed expectations that the KF-X fighter jets will compete in the global market with fifth-generation fighter jets such as the U.S. aerospace giant Lockheed Martin's F-35 and F-22, based on price and technology competitiveness. According to the KAI, the KF-X is designed as a 4.5-generation jet whose basic hardware and platform could be used for further development and conversion into a fifth-generation one with improved "stealth" technologies.

"As the KF-X has been equipped with hardware to become a stealth fighter, we are currently exploring ways to apply stealth technologies to the jet, although we have yet to specify details for further developments as the military has yet to present the details necessary for further developments after Block I and Block II stages of the KF-X development project," Jung Kwang-sun, director general of the KF-X Program Group under the Defense Acquisition Program Administration (DAPA), told reporters who were visiting KAI headquarters, Feb. 24.

The KF-X project is an "evolutionary development" project which is divided into two phases. The first phase, or the Block I stage, is about developing the basic system of the fighter jet from 2016 to 2026. The second phase, or the Block II stage which would be carried out from 2026 to 2028, is about adding more weapon systems.

While the core equipment of the KF-X has been developed with domestic technologies, including active electronically scanned array (AESA) radar, infrared search and track (IRST) equipment, electro-optical target tracking (EO TGP) devices and electronic warfare (EW) suite, the target ratio of localization is 65 percent, in terms of the total costs of the parts used for the jet.

With 10 stations on the jet, about 50 different weapons combinations that weigh up to 7.7 tons can be carried. The total fuel capacity of the jet is 5.3 tons and it has aerial refuelling capability.
