JET-JET TEMPUR GENERASI KE 5 STEALTH (SILUMAN)

 KFX 201 (INDONESIA-KORSEL) 5TH GERERATION

16 Juli 2010, Seoul -- Indonesia sepakat bergabung dalam proyek pengembangan jet tempur KF-X,Korea Selatan (Korsel), yang tertunda selama beberapa tahun akibat masalah teknis dan pendanaan.

Kedua negara juga sepakat untuk bekerja sama dalam produksi dan pemasaran jet tempur tersebut. “Indonesia akan memperoleh sekitar 50 jet tempur KF-X dengan menanggung 20% biaya pengembangan proyek bernilai miliaran dolar AS itu,” ungkap Kementerian Pertahanan Korsel dalam rilisnya. Kesepakatan itu ditandatangani di Seoul oleh Komisioner Kementerian Pertahanan Korsel dan Sekretaris Jenderal (Sekjen) Kementerian Pertahanan (Kemhan) Indonesia Marsekal Madya TNI Erris Herryanto kemarin.Menurut Juru Bicara Kementerian Pertahanan Korsel,proyek ini akan kembali dimulai awal tahun depan. Adapun produksi jet-jet tempur baru dilakukan setelah studi kelayakan rampung pada akhir 2012.

“Kami juga memerlukan mitra asing yang akan mentransfer teknologi dan suku cadang utama jet tempur tersebut,” ujarnya tanpa menyebutkan total dana yang diperlukan. Proyek jet tempur KF-X sebenarnya sudah diluncurkan tahun 2000,tapi ditangguhkan karena masalah teknis dan ekonomi.Presiden Lee Myung-bak pada Januari lalu setuju untuk mendorong proyek tersebut di tengah meningkatnya ketegangan antara Korsel dan Korut. Kementerian Pertahanan RI membenarkan kerja sama dengan Korsel dalam memproduksi pesawat tempur KF-X.Pemerintah Indonesia bisa menggunakan fasilitas milik PT Dirgantara Indonesia.

“Kami tidak hanya membeli pesawat tempur, tetapi juga ingin bekerja sama dalam produksinya.Kami berharap fasilitas milik PT Dirgantara Indonesia bisa digunakan untuk hal itu,”kata Juru Bicara Kemhan BrigjenTNI I Wayan Midhio. I Wayan mengatakan KF-X adalah pesawat tempur jenis baru yang memiliki kemampuan tempur andal. Bahkan.Wayan berani mengklaim kemampuan KF-X ini di atas F-16, tapi masih di bawah F-35.Wayan mengakui pemerintah berencana membeli 50 buah KF-X begitu pesawat selesai diproduksi.Tidak hanya membeli, pemerintah juga membantu memasarkan pesawat itu ke negara-negara lain.

“Saya kira, prinsip yang paling utama adalah sekarang negara kita bisa ikut terlibat dalam proses produksinya,jadi ada transfer teknologi,”tuturnya. Juru Bicara TNI Angkatan Udara Laksamana Pertama Bambang Samudro menyatakan kerja sama produksi pesawat tempur dengan Korsel ini adalah bagian dari rencana kedua pihak untuk meningkatkan kemampuan dalam memproduksi pesawat tempur.“Ini adalah kerja sama jangka panjang kedua negara.Kesepakatan ini dicapai setelah melalui pembicaraan panjang,”tuturnya.

Kerja sama produksi pesawat tempur ini, lanjut Bambang,dimulai tahun ini sementara segala persiapan seperti survei dan membuat prototipe akan dilakukan hingga 10 tahun ke depan.Bambang menambahkan, TNI AU akan memakai semua pesawat itu jika pemerintah membelinya.“Yang paling utama, kita tidak hanya membeli, tetapi kita bisa membuat sendiri peralatan tempur kita sebagaimana yang pemerintah inginkan,”katanya. Sekjen Kemhan Marsekal Madya Erris Herryanto sebelumnya mengatakan Indonesia layak untuk berpartner membuat pesawat tempur.Menurut dia,langkah kerja sama dengan Korsel merupakan suatu kemajuan karena tidak banyak negara yang bisa membuat pesawat tempur.


Apabila memiliki pabrik pesawat tempur, Indonesia tidak akan bergantung lagi kepada negara lain. Namun Erris saat itu belum bisa merinci beberapa hal yang tertuang dalam perjanjian itu,termasuk apa saja yang akan diperoleh Indonesia dan apa saja yang harus disediakan. ”Yang jelas, kita punya PT Dirgantara Indonesia dan tenaga ahli,”kata Erris. Dia juga mengungkapkan, spesifikasi pesawat tempur KF-X ini kira-kira berada di atas F-16,tetapi di bawah spesifikasi F-35.Adapun kebutuhan biaya yang diajukan sekitar USD8 miliar dengan jangka waktu kerja hingga tahun 2020.Pada 2020 diharapkan sudah bisa disiapkan lima prototipe.Dari keseluruhan anggaran itu,Indonesia diharapkan menanggung sebesar 20%.

Berdasar informasi yang berkembang, pesawat tempur ini rencananya akan rilis pada 2020 .Rencananya KF-X akan disokong mesin kembar setara dengan kelas General Electric F414 atau SNECMA M88 yang digunakan pada F/A- 18E/F Boeing dan Dassault Rafale. SNECMA menggambarkan M88 sebagai landasan dari keluarga mesin generasi baru. Mitra yang akan dirangkul untuk pengembangan mesin adalah Lockheed Martin yang sebelumnya terlibat dalam desain dan pengembangan pelatih Korea Aerospace T-50 jet supersonik. Proyek KF-X juga akan merangkul sejumlah perusahaan asing. Perusahaan-perusahaan asing akan membayar hingga 30% dari program.

Kepala Tim Pengembangan Sistem Udara Korsel Kolonel AU Dae Yeol-lee sebelumnya mengungkapkan, BAE Systems telah menyatakan minatnya dalam mengembangkan radar, sedangkan Alenia Aeronautica dipercaya untuk memasok senjata utama dari KF-X dan bertanggung jawab pada program neuron kolaboratif untuk mengembangkan teknologi European combat-drone.

Jet Siluman Cina J-14

: BERITA HANKAM

J-XX, J-14 (China, 2018)

This is the Chinese 5th generation fighter (4th generation by Chinese nomenclature) under development in Shenyang Aircraft Industry. Its introduction is planed for 2018.

No details of the aircraft were given yet to the public, but it is almost certainly designed for supersonic cruise without afterburning. China is probably working on two 5th generation concepts – one would be a heavy twin-engine fighter probably of about the same size as the F-22, and the other is a single-engine aircraft probably closer to the F-35.

Sukhoi PAK FA T-50 (Russia, 2015)

The twin-engined Sukhoi PAK FA (Russian: Перспективный авиационный комплекс фронтовой авиации, literally "Future Frontline Aircraft System") is the first non-American 5th generation fighter. It is developed by Sukhoi OKB for the Russian Air Force. Its first flight was in January 29th 2010, and introduction is planed for 2015. Estimated cost of 1 fighter is US$100 million.

As mentioned, the Russian Defense Ministry will purchase the first 10 of the T-50 after 2012 and then 60 after 2016. Also, Sukhoi director Mikhail Pogosyan has projected a market for 1,000 aircraft over the next four decades, which will be produced in a joint venture with India, 200 each for Russia and India and 600 for other countries.

General performances

Data available to public is unreliable, but according to www.globalsecurity.org, the T-50’s top speed is Mach 2.45 (2,600 km/h, 1,615 mph).
Ferry range is 5,500km, service ceiling 20,000m and g limit is +11g.
It seems that the PAK FA is going to surpass the US’s F-22 Raptor, and it going to be cheaper at the same time due to its more simple structure.
The PAK FA also has a bigger weapons bay and greater fuel capacity. Innovative wing leading edge radar of lower frequency (perhaps L band) would be able to locate stealth aircraft like the F-22, a capability that the F-22 does not have.

However, premier of Russia Vladimir Putin and Russian media has spotted that the stealth technology along with electronic equipment are not fully developed yet for this aircraft, so it need to be reequipped to regain its title as 5th generation fighter.

F-22 Raptor (USA, 2005)

This is the world’s first and so far only produced fighter classified as 5th generation aircraft – it is introduced in December 15th 2005, but it’s first prototype, YF-22, had his first flight in September 29th 1990. 9 years earlier (1981), USAF identifies need to replace F-15. Manufacturers are Lockheed Martin Aeronautics and it’s partner Boeing Integrated Defense Systems. They produced 168 units so far (1 unit costs ~ US$150 million).

This fighter is a single-seat, twin-engine aircraft designed to be dominant in the air-to-air combat, but its complex structure and size makes it too expensive right now. On the other side, the smaller F-35 is less dominant and cheaper fighter, so it will be produced for selling.  

General performances

According to Lockheed Martin, the F-22 is the 2.0 Mach machine (Mach 1 = speed of sound) – they said that with afterburners, speed is "greater than Mach 2.0" (2,120 km/h, 1,317 mph).
According to AirForces Monthly magazine, the highest achieved speed by this aircraft is Mach 2.25 (2,410 km/h, 1,500 mph).
Range of F-22 Raptor is 2,960km, service ceiling (max altitude) is 19,802m, combat radius (max distance from the airbase) is 759km and g limit is -3.0/+9.0g.

This fighter is capable of maintaining a constant angle of attack of over 60°, yet still having some control of roll. During June 2006 exercises in Alaska, F-22 pilots demonstrated that cruise altitude has a significant effect on combat performance, and routinely attributed their altitude advantage as a major factor in achieving an unblemished kill ratio against other US fighters and 4th/4.5th generation fighters.

F-35 Lightning II (USA, 2014)

This is the single-seat, single-engine fighter descended from the X-35, the product of the Joint Strike Fighter (JSF) program. First flight of prototype was in December 15th 2006, and its introduction is planed for 2014.

As mentioned, The United States intends to buy a total of 2,443 aircraft for an estimated US$323 billion, making it the most expensive defense program ever. Its development is being principally funded by the United States, with the United Kingdom, Italy, Netherlands, Canada, Australia, Denmark, Norway and Turkey providing additional funding. It is being designed and built by an aerospace industry team led by Lockheed Martin with Northrop Grumman and BAE Systems as major partners.  The F-35 is likely to cost between US$65–120 million – it will be less dominant then F-22 in air-to-air combat, but much more economical (commercial).

To keep operating costs down, designers are developing 3 types of this aircraft: F-35A - conventional take off and landing (CTOL) variant, F-35B - short-take off and vertical-landing (STOVL) variant and F-35C - carrier-based CATOBAR (CV) variant. The F-35 is intended to be the world's premier strike with close and long range air-to-air capability second only to that of the F-22 Raptor.

General performances

According to Aviation Week site, max speed of F-35 Lightning II is Mach 1.67 (2,065 km/h, 1,283 mph).
Range is 2,220km, service ceiling is 18,288m and combat radius is 1,090km and g limit is 9g.

Mitsubishi ATD-X Shinshin (Japan)

The “Advanced Technology Demonstrator – X” (ATD-X) is a prototype being developed by Mitsubishi Heavy Industries for Japanese Ministry of Defence. It is not officially planed for production, but its first flight is expected in 2014.
The ATD-X will be used as a technology demonstrator and research prototype to determine whether domestic advanced technologies for a 5th generation fighter aircraft are viable, and is a 1/3 size model of a possible full-production aircraft. It is mostly inspired by F-22 Raptor.
