Indonesia-Korsel Buat Pesawat Tempur.
Kamis, 3 Juni 2010 | 03:21 WIB
Jakarta, Kompas - Tahun ini, Indonesia diharapkan bisa menandatangani perjanjian kerja sama dengan Korea Selatan untuk pembuatan pesawat tempur. Dengan demikian, Indonesia diharapkan tak akan bergantung kepada negara lain dalam hal penyediaan pesawat tempur.
Hal itu disampaikan Sekretaris Jenderal Kementerian Pertahanan Marsekal Madya Erris Herryanto, Rabu (2/6). ”Kemungkinan besar tahun ini sudah ditandatangani,” kata Erris. Kesepakatan untuk studi kelayakan ditandatangani tahun lalu.
Kementerian Pertahanan menerima hasil studi kelayakan pada Juli 2009. Dalam studi itu disebutkan, Indonesia layak untuk berpartner membuat pesawat tempur. Spesifikasi pesawat tempur dengan kode KFX ini kira-kira berada di atas F-16, tetapi di bawah spesifikasi F-35.
Menurut Erris, langkah tersebut 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.
Menurut Erris, masalah komitmen dan perjanjian secara rinci tengah dibahas. Namun, tidak ada perbedaan yang mencolok. Saat ini tengah disusun redaksional perjanjian di antara kedua belah pihak. Erris 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.
Kebutuhan biaya yang diajukan sekitar 8 miliar dollar Amerika Serikat dengan jangka waktu kerja hingga tahun 2020. Pada tahun 2020 diharapkan sudah bisa disiapkan lima prototipe. Dari keseluruhan anggaran itu, Indonesia diharapkan menanggung sebesar 20 persen. Akan tetapi, ujar Erris, belum ada kesepakatan soal keuangan tersebut.
Mengenai pengadaan pengganti pesawat OV-10 Bronco, Direktur Pengadaan Direktorat Jenderal Sarana Pertahanan Marsekal Pertama Mukhtar Lubis mengatakan belum ada kepastian. Mabes TNI masih mengevaluasi masukan dari TNI AU. Menurut Mukhtar, pihaknya belum bisa memastikan bahwa pesawat yang akan dibeli adalah Super Tucano dari Brasil. ”Masih harus diteliti dulu spesifikasi dan juga prosedurnya,” katanya.
Soal Sukhoi, kata Mukhtar, pihaknya tengah mengirim sejumlah personel untuk mengikuti pelatihan. Hal itu dilakukan untuk persiapan kedatangan lagi tiga pesawat Sukhoi Su-27SKM yang diharapkan tiba pada September mendatang. ”Soal persenjataan, kita beli dengan paket yang berbeda,” kata Erris. (EDN)
ROK's New Stealth 5th Generation fighter
KFX SINGLE ENGINE SERIE.
July 22, 2010: South Korea and Indonesia have agreed to jointly develop a new fighter, the KFX. This would be an aircraft with capabilities somewhat beyond the top-line American F-16 Block 60. The best example of this is a special version of the Block 60 developed for the UAE (United Arab Emirates). The UAE bought 80 "Desert Falcons" (the F-16E) which is optimized for air combat. It is a 22 ton aircraft based on the Block 52 model, but with an AESA (phased array) radar and lots of other additional goodies.
KFX development is expected to take ten years and cost $2 billion. South Korea hopes to build on the work it did to develop its T-50 jet trainer. This is a 13 ton, two seat, single engine aircraft that is also available as a combat model (the F-50), which carries a 20mm autocannon and up to three tons of bombs and missiles. The KFX would weigh twice as much, have one or two engines, a single seat and the ability to carry twice as much weight in weapons. The KFX is expected to look more like the Eurofighter Typhoon, than the T-50 or F-16. The KFX is also expected to cost $50 million each, have advanced electronics (including an AESA radar). Indonesia will provide 20 percent of the development costs and buy fifty of the KFX’s. South Korea will buy 150-250 of the new aircraft, to replace its current fleet of elderly American F-4s and F-5s. This is an ambitious undertaking, and success is not certain, especially when the timeline, budget and aircraft performance are concerned.
The competition remains the U.S. F-16, which is one of the most modified jet fighters in service. While most are still called the F-16C, there are actually six major mods, identified by block number (32, 40, 42, 50, 52, 60), plus the Israeli F-16I, which is a major modification of the Block 52. The F-16D is a two seat trainer version of F-16Cs. The various block mods included a large variety of new components (five engines, four sets of avionics, five generations of electronic warfare gear, five radars and many other mechanical, software, cockpit and electrical mods.)
KF-X REJECTED MODEL.
South Korea's New 5th Generation Stealth Fighter Concept
Now the South Koreans are planning to make a "5th generation fighter" that strongly resembles the F-22A (in a way), YF-23 and the proposed J-XX design.
Korean stealth fighter project. (KF-X, which is 12,000,000,000 dollar project to develop stealth fighter by 2017 and begin to produce by 2022.) Now this project comes out to surface.
KAI (Korea Aerospace Industries) is trying to push NSC (National Security Council) to replace KFX to F-50 (which is fighter-version of T/A-50) but ROKAF will indefatigable to continue KFX project. This is really interesting story to discuss about.
There was news (Sep, 2005) from Korean media that ADD is in the progress to design model and working on concepts and shapes. These two (101, 201) models only announced to media.
And here is the picture and video clips from ADD(Agency for Defense Development, which is South Korean military research institute) website.
These are video clips of wind-tunnel test and a picture that have published on ADD webpage. There I have found two model of KFX and these are named 101 and 201. KFX-101 model looks like an F-22 mixed with F-35. And KFX-201 looks like a stealth version Rafale, which has canard and delta wing.
Joint Servo Actuator design
Operating computer design
Data link design
Equipment integration and control
Aircraft - Equipment linking system design
Air-to-Air missile design
'Smart Structure' design
Single-piece complex body design
Newest Delta-Canard design and 2 other tech.
Electronic engine-control system design
And other other technologies that it's include RAM paint design
p/s: Japanese are on progress of developing ATD-X (might be the Japanese X-plane project of F-3 stealth fighter), and there is "well known" rumor about Chinese J-XX (or J-14) project. And here comes KFX, and it's going to be interesting competition to watch.

Saab Offers Supercruising Stealth to South Korea
Aviation Week & Space Technology

South Korea?s combat aircraft requirement draws out advanced proposals from Western fighter houses
A Saab proposal to co-develop a stealth fighter with South Korea is raising the prospect of an Asian-European aircraft emerging to compete with the Lockheed Martin F-35 Lightning.
The South Korean project to build an advanced combat aircraft alternatively offers to fund developments of the Eurofighter Typhoon or to help sustain Boeing?s waning fighter business?but there is also a strong chance that the ambitious program will collapse into yet another F-35 order.
Saab is pitching a new design for a supercruising stealth fighter to South Korea, as well offering the possibility of joining the Gripen next-generation program (AW&ST June 30, p. 42).
Boeing is putting forward developments of the F-15, including reviving a 1990s concept without tail fins, and it has also offered a new fighter design.
EADS is pushing developments of the Typhoon beyond the Tranche 3 standard, and also flagging the opportunity of participating in its combat drone project. It may also have submitted a clean-sheet-of-paper fighter concept.
Lockheed Martin meanwhile is telling Seoul that the F-35 Lightning will meet its needs. That?s not surprising, since it has no business interest in supporting South Korean ambitions to co-develop a stealth fighter, which would surely become an F-35 competitor.
The diverse range of offerings from the four manufacturers reflects uncertainty in South Korea itself over combat aircraft development. The air force wants an advanced fighter, but various factions in the government, industry and military are debating whether the country should fill that requirement by buying off the shelf or by taking part in development of a new aircraft or major derivative.
The country has two substantive fighter requirements, F-X Phase III for 60 aircraft and then F-XX for 120. It also has a parallel domestic stealth fighter development program, KFX. The F-XX requirement calls for fifth-generation aircraft, so the hope is that KFX will fill that need through a joint program between South Korean and foreign industry, with the latter carrying up to 30% of the development cost.
But KFX is up for review this month by the administration of new President Lee Myung-bak. It may be canceled or restricted to co-production or assembly of an existing aircraft, boosting Lockheed Martin?s hopes of an order for the F-35. An intermediate possibility would be South Korean involvement in less advanced developments of current production aircraft.
The manufacturers presented their ideas at an air force seminar in Seoul on June 26.
Saab has circulated two series of designs for South Korea, for single and twin aircraft, recent iterations of which have been designated P305 and P306, respectively. Its presentation at the seminar showed only the twin-engine design, probably reflecting South Korean views on how large an aircraft is needed. The air force?s Warfare Development Group has described the KFX as having a capability between that of the F-15 and F-16. By ?capability? it must mean weight and thrust class, since a new stealth aircraft would be much more capable than even updates of the 1970s designs.
Saab gave no specifications for its design but the external weapons shown on a drawing suggested an aircraft length of 17-18 meters (56-59 ft.). Span is much less than the length, possibly about 12 meters. If those rough estimates are correct, then the Saab stealth fighter would be at least as large as the Typhoon.
Saab shows single- and tandem-seat versions of the design. Inlet configuration is similar to the F-22?s, and the tail fins are canted. The trailing edge of the main-plane is swept forward, again like the F-22?s, but the leading edge looks significantly less swept. A gun is mounted abreast the left inlet duct.
The manufacturer promotes the aircraft as a balanced multirole design offering broadband stealth, supercruise, ?range and endurance,? integrated sensors, avionics and weapons, and situational awareness through the human-machine interface. It also claims attractive ?low life-cycle cost, growth potential [and] exportability,? while dismissing ?extreme stealth? as ?suitable for tailored platforms.?
Internal weapons stowage seems to be limited, since Saab says the bays are optimized for the air superiority role, although it still describes the aircraft as multirole in high-threat scenarios. External stores would be carried for low-threat scenarios. One of the three bays is behind the pit and between the inlets, and the other two are in the lower corners of the fuselage under the wing.
With domestic development, ?upgrades and changes to the aircraft can be implemented according to Republic of Korea Air Force priorities without interference by [the] seller?s government, etc.,? Saab argues, in a clear jab at Lockheed Martin. Brig. Gen. Lee Hee-woo, head of the Warfare Development Group, is opposed to a South Korean order for the F-35, saying the inaccessibility of its software will deny ?operational sovereignty? to the user.
Within South Korea, the defense ministry?s Agency for Defense Development is the most gung-ho about KFX. It would have little to do if KFX were canceled, so it is lobbying for the project to fill the F-XX requirement and has already produced stealthy concept designs.
Perhaps surprisingly, Korea Aerospace Industry is far less keen on an advanced development. Apparently mindful of its technological limitations, it would like the government instead to order the proposed F-50 combat version of the T-50, its Gripen-sized supersonic trainer.
The T-50 was developed under the guidance of Lockheed Martin, using the F-16 planform. Holding out the hope of a later development that might satisfy the urge to advance domestic technology, Korea Aerospace is also showing a concept of a delta-wing F-50XL, an analog of the F-16XL that Lockheed Martin offered to the U.S. Air Force in 1982. But the F-50XL concept differs from the F-16XL in having a wing with a straight leading edge, rather than a cranked arrow, and it has canted tail fins.
Some politicians are in favor of the F-35 for the F-XX requirement, and it is clearly well placed because of its combination of capability and cost.
The F-50 seems a long shot. Air force Chief of Staff Kim Eun-ki says the immediate priority is to continue buying fighters in the class of the F-15K until neighboring countries begin acquiring fifth-generation fighters.
Hence Boeing?s opportunity in pushing the F-15K, of which South Korea has already ordered 61. Boeing updated the F-15E to create the F-15K for F-X Phase I, added features again for Phase II, and now says the Phase III model would have a next-generation active electronically scanned radar, electronic warfare suite, and advanced memory and weapon systems.
The KFX would follow that, and Boeing seems to have shown the finless F-15 as a possible candidate for the advanced program. The advantage of such an aircraft would be lower radar reflections, weight and drag. Brad Jones, Boeing?s KFX program manager, tells Aviation Week & Space Technology that the Super Hornet could also be offered for KFX, and he adds that Boeing has also proposed a completely new design.
Jones suggests, however, that given the cost and development timescale implications of an all-new fighter, the defense ministry will most probably pursue the development of an existing aircraft to meet the KFX requirement.
The F-35 is the main competitor for F-X Phase III, as well as a strong candidate for F-XX. The immediate need to keep buying aircraft in the F-15K-class does not necessarily exclude the F-35, which is significantly larger than the Typhoon, for example.
The EADS offering is an improved Typhoon. In its presentation, EADS suggests new interface technologies, further development of sensor fusion and sensor upgrades, among others.
An EADS representative says: ?The EADS approach to KFX is based on an overarching partnership with the Republic of Korea [RoK] for the future combat air system capability development, including on the one hand RoK participation in the development of the Eurofighter future enhancements, and on the other the joint development of an unmanned combat air system, offering the perfect mix in terms of RoKAF future capability, program affordability and Korean industry workshare.?
A top South Korean government think tank responsible for economic policy analysis judged the KFX economically not worthwhile in December 2007 and stood fast when ordered by the defense ministry to reconsider its view (AW&ST Feb. 11, p. 19). The new government under President Lee, whose defense policy is vague, stresses economic efficiency first and foremost.
According to an industry source, one of the foreign companies offering to participate has assessed the program cost at 10 trillion won ($9.5 billion).
A committee chaired by Defense Minister Lee Sang-hee will conduct this month?s review.
The Agency for Defense Development has revealed successful ground tests on radar-absorbing material on a McDonnell Douglas F-4 fighter. The timing of the May announcement could be interpreted as an attempt to gain publicity for the country?s advanced aerospace efforts, helping to keep the KFX alive.
It isn?t clear whether the South Korean material is structural or a coating, nor, if it is a coating, whether it is a paint or a metallic compound.
The agency says it has been studying the material since 1999 and received good results from trials in an indoor test facility. The next step will be flight tests, which will be conducted ?soon,? it says.
Taiwan, whose technological capability is similar to South Korea?s, tested an imported anti-radar material on an AIDC AT-3 jet trainer in 2001-03. The supplier was ?an overseas Taiwanese man,? local media reported.
The Korean agency also says it has acquired technology for stealth shaping and analysis. In a November presentation, it showed pictures of a 1/10 scale model in an indoor radar range.
The model represented the agency?s K100 concept for a fighter that would resemble a twin-engined F-35 with a multifaceted nose.
The KFX project dates back to the South Korean Joint Chiefs of Staff?s decision in November 2002 to acquire up to 120 fighters, which is the requirement known as F-XX. In 2004-06 it became the basis of the agency?s fighter design study, which spawned two concepts, the K100 and K200, the latter being a twin-engined canard-delta fighter.
Like Japan?s full-scale radar cross-section model tested in France in 2005, the model probably closely reflects the agency?s ideas of what sort of aircraft it currently has in mind (AW&ST Feb. 11, p. 36).
SEOUL - South Korea and Indonesia signed a memorandum of understanding (MoU) July 15 to jointly develop a 4.5-generation fighter jet with greater capabilities than those of the KF-16.
Indonesia agreed to bear 20 percent of the development costs of the 5 trillion won ($4.1 billion) project over the next decade, according to South Korea's Defense Acquisition Program Administration (DAPA). South Korea plans to foot 60 percent of the bill, with the balance to come from other government or corporate partners.

* Air Warfare
The two Asian countries will work together in production and marketing of the KF-X aircraft. Indonesia also agreed to buy about 50 KF-X aircraft when mass production begins.
The agreement follows a KF-X letter of intent signed in March 2009 by South Korean President Lee Myung-bak during a visit to Indonesia.
The MoU is "the reflection of our commitment and strong bilateral cooperation in the fields of defense industry," Eris Herryanto, the director general of defense facilities at Indonesia's Defense Ministry, said in a speech ahead of the signing ceremony here with DAPA Commissioner Byun Moo-keun at South Korea's Defense Ministry.
"I'm confident that through signing this MoU on joint development of the KF-X Fighter, the outcome of cooperation shall be implemented at its earliest convenience," Herryanto said. "The realization of joint development, production and marketing will be finalized with our very own maximum of development capability."
Col. Lee Jong-hee, director of DAPA's KF-X development team, said his agency is negotiating with Turkey and the United Arab Emirates on investments in the KF-X program.
"There are two options on the table. One is to lure financial investments from other nations, such as Turkey and the United Arab Emirates," Lee said. "The other is to receive investments from Western aircraft makers wishing to participate in the KF-X."
Boeing and Lockheed Martin of the United States, the European defense group EADS and Sweden's Saab have shown their interest in the KF-X program, which is linked to South Korea's F-X III fighter acquisition competition set for next year. Under the F-X III program, South Korea plans to purchase 40 to 60 stealthy fighters.
Initiated in 2002, the KF-X program was originally aimed at producing and marketing about 120 aircraft, stealthier than Dassault's Rafale or the Eurofighter Typhoon, but not as stealthy as Lockheed's F-35 Lightning II.
Due to questions about the program's economic and technical feasibility, the South Korean government refocused the requirement last year to produce fighter jets on par with the F-16 Block 50 to replace older F-4 and F-5 aircraft.
Key requirements for the KF-X include an active electronically scanned array radar, an electronic warfare suite, an infrared search-and-track system, super-velocity intercept and supercruise capabilities, and air-to-air, air-to-ground and air-to-sea capabilities.
In the first 11 years of exploratory and full-scale development, about 120 KF-Xs would be built, and more than 130 aircraft would be produced after the first-phase models reach initial operational capability.
