Lawmakers call for audit of KF-X

By Jun Ji-hye

Lawmakers from the ruling and opposition parties have asked the state auditor to launch an inspection into the country's troubled fighter jet development program.

They claim the KF-X project, worth 8.5 trillion won, is in jeopardy because the Defense Acquisition Program Administration (DAPA) failed to acquire the necessary technologies.

Rep. Chung Doo-un of the ruling Saenuri Party, who chairs the National Assembly Defense Committee, said Tuesday, "If there is nobody who will take responsibility for the project in crisis, an audit by the Board of Audit and Inspection (BAI) will be unavoidable."

The KF-X project, which calls for developing indigenous fighter jets by 2025 to replace the Air Force's fleet of F-4s and F-5s, faced a big setback in April after the U.S. government refused to allow Lockheed Martin to transfer to Korea four core technologies related to the F-35 stealth fighter for security reasons.

The four technologies, including the active electronically scanned array (AESA) radar, are considered critical in the development of the high-tech fighter jet.

Following the rejection, DAPA kept maintaining that the nation will be able to develop such technologies domestically.

But Rep. Chung said the explanation is unacceptable.

"Just two months ago, Korea asked the United States to allow the transfer of four technologies, and right after the transfer foundered, DAPA said the nation can develop them domestically. Who will be able to understand this?" he said.

He noted that it is common sense to review a project again if any changes in conditions arise.

Rep. Yoo Seong-min of the ruling party and Rep. Yoon Hu-duk of the main opposition New Politics Alliance for Democracy also said the inspection of the botched project is necessary.

In response, DAPA Minister Chang Myoung-jin told lawmakers that if the nation fails to develop the core technologies domestically, it would buy a complete product from a foreign company.

Chang also said if a budget bill recently approved by the Defense Committee is passed at the Assembly as it is, the project would be behind schedule for about two to three years.

DAPA had initially requested 161.8 billion won for the KF-X project next year, but the Ministry of Strategy and Finance cut it to 67 billion won in September, which was approved by the Assembly Defense Committee at the end of last month.

Chang added that Korea is planning to sign a tentative deal with Indonesia as early as next week for the Southeast Asian country to join the KF-X project.

In October last year, Jakarta agreed with Seoul to participate in the project, paying 20 percent of the costs and later buying 50 aircraft.

But critics say there might be a problem with the deal, citing the timing delay.

On Oct. 6, DAPA said it would have signed that deal by the end of that month.

Korea Aerospace Industries agrees KFX investment deal with Indonesia
Jon Grevatt, Bangkok - IHS Jane's Defence Industry
22 November 2015

Korea Aerospace Industries (KAI) and the Indonesian government signed an agreement on 22 November to formalise proposed investment and workshare arrangements to support the development of the Korean Fighter Experimental (KFX) 4.5-generation fighter aircraft.

The agreement is framed by an accord signed by the governments of South Korea and Indonesia in October 2014 under which South Korea will pay 80% of the costs associated with the joint engineering and development phase of the KFX, with Indonesia paying the remaining 20%.

The newly signed deal, which in essence reaffirms Indonesia's investment in the project, will become operational once KAI formally secures the contract with South Korea's Defense Acquisition Program Administration (DAPA) to complete the development of KFX aircraft. KAI was named preferred developer of the KFX in March, and a contract to undertake the work is expected to be signed before the end of the year.

Under the terms of the newly announced agreement, Indonesia has agreed to invest about KRW1.7 trillion (USD1.5 billion) of the total KRW8.7 trillion in KFX development costs.

KAI said that in return for its investment, Indonesia's state-owned aerospace manufacturer, PT Dirgantara Indonesia (PTDI), will participate in the design phase of the aircraft and produce unidentified components. PTDI will also secure rights to some areas of intellectual property involved in developing the KFX and have access to one of six planned prototypes.

KAI plans to commence manufacturing the KFX from 2025. Company officials have previously suggested that about 250 KFX fighter aircraft could replace the Republic of Korea Air Force's ageing F-4E Phantom and F-5E Tiger II aircraft and, ultimately, its F-16 Fighting Falcon platforms. KAI also expects to export several hundred KFX fighters to countries that include Indonesia.

The KFX is envisaged as a single-seat, twin-engine, multirole aircraft equipped with stealth features, active electronically scanned array radar, and internal weapons carriage.

Das 21 tecnologias que a Coreia do Sul disse que o Eua aprovou 3 eles colocaram objeções 2 são referentes a alguma coisa na concepção semi stealth e uma é referente a integração de bi motores, ou seja das 25 tecnologias apenas 18 estão garantidas, se pretendia fechar o acordo com as 21 tecnologias neste mês, mas as negociações foram estendidas ate janeiro de 2016 por causa da negação de mais 3 tecnologias.

Coreia do Sul conseguiu copiar uma peça do motor do F15k Ge F110 utilizando uma impressora 3d, ate o momento foram feitas 14 unidades.
Cada motor F110 necessita a troca da tampa do compressor 10 vezes ao ano e tem o preço unitário de US$40 mil, a importação demora cerca de 60 dias.
Ao utilizar a impressora 3d o custo unitário saiu por US$32 mil e demora cerca de 20 dias para ficar pronto, com isto se conseguiu uma economia de US$300 mil neste ano.

South Korea’s rapid weapons exports expansion causes strains with U.S.
November 26, 2015

By YOSHIHIRO MAKINO/ Correspondent

SEOUL--South Korea has increased its weapons exports more than 12-fold over the past decade, triggering friction with the United States because much of the technology involved originated there, sources say.

It was stopped from selling the T-50 advanced trainer aircraft to Uzbekistan this year, according to a source knowledgeable about South Korea-U.S. relations.

"The United States did not want the technology to go to a nation that once belonged to the Soviet Union," the source said.

The T-50 is among the more popular South Korean defense systems and is manufactured by Korea Aerospace Industries Ltd. (KAI). The company is seeking to sell the jets to the United States, as it is in the process of replacing about 1,000 trainer aircraft. The 1,000 jets would cost about 38 trillion won ($33 billion, or 4 trillion yen).

"Large amounts of technology from the United States have been used in the T-50,” said a military source. “Because experiments during the development stage have been passed, the plane can now be produced at cheaper prices.”

On Nov. 22, South Korea signed a provisional contract with the Indonesian government for joint development of a fighter jet.

Other sales pitches have been made to Thailand for the purchase of training aircraft and to Indonesia for a diesel-powered submarine.

The provisional contract with the Indonesian government involves KAI. Plans call for developing a fighter jet that is more advanced than the F-16, of which 4,600 have been sold throughout the world, and cheaper than the F-35, a stealth fighter jet.

A KAI official said, "We are seeking to sell 1,000 fighter jets to the South Korean and Indonesian militaries for a profit of 180 trillion won."

But when South Korea asked the United States for the transfer of 25 types of technology that would be needed in developing the fighter jet, Washington declined to provide four of them.

A military source said, "The objective of weapons exports by South Korea is purely to pursue economic benefits. However, there is a slight sense of being a 'merchant of death,' and it also faces the challenges of not being able to go against U.S. strategy."

According to the South Korean government, weapons exports in 2013 totaled about $3.4 billion, which represents a drastic increase of 12.8 times over 10 years ago.

Other than the T-50, South Korea’s lucrative defense systems include the K-9 self-propelled howitzer, which has a firing range of 40 kilometers, similar to weapons made in the United States and Japan

The exports have been sent to about 80 nations, including the United States, as well as those in the Middle East and Southeast Asia.

Efforts to expand its international customer base began during the administration of President Lee Myung-bak. His successor, President Park Geun-hye, has continued that course and during talks with leaders of Southeast Asian nations has often asked for cooperation among the defense sectors.

US to provide maximum support for S. Korea's KF-X project: State Department

The United States will provide maximum support for South Korea's indigenous fighter jet development project, the State Department said Tuesday, dismissing speculation that Washington might be reluctant to back the program.

The State Department is responsible for approving U.S. defense giant Lockheed Martin's promised transfer of key technologies to South Korea for the fighter program, known as the "KF-X" project. Speculation about U.S. reluctance arose after reports that the department was negative about approving the transfer of some technologies.

"The United States continues to support the Republic of Korea's defense programs and priorities through the transfer of many of our most sensitive defense technologies. We seek to support the KF-X indigenous fighter program to the maximum extent possible," Katina Adams, a State Department spokeswoman, said in response to a question from Yonhap News Agency.

"The U.S. government is in discussions with Lockheed Martin to address ROK areas of concern. We will continue to work closely with Lockheed Martin throughout this process to ensure continued support to the KF-X program," she said.

South Korea agreed with Lockheed Martin last year to receive 25 combat jet technologies and the two parties have been negotiating the terms of transferring 21 of the technologies after the U.S. government decided earlier this year not to transfer the other four sensitive technologies.

Recent media reports said that the U.S. decided to disallow the transfer of three more technologies. But the department spokeswoman said no final decision has been made.

"Programs like the KF-X are large and complex. As a result, there is often an iterative process whereby export licenses are amended as the program matures and becomes better defined," the spokeswoman said.

A team of experts from the Defense Acquisition Program Administration, South Korea's state arms procurement agency, has arrived in the U.S. for talks with Lockheed Martin on the technology transfer, according to an informed source who spoke on the condition of anonymity.

"I understand that the basic position of the U.S. is that it will resolve the issue in a positive manner, taking into account technological aspects, as well as the South Korea-U.S. alliance," the source said.

The talks are expected to run through the weekend as the two sides negotiate the details of each of the technologies under discussion. (Yonhap)

Se comenta que o Eua perguntou o que realmente vocês necessitam das 21 tecnologias da lista tudo não vai dar.

Co-development of Jet Engine

Hanwha Techwin, GE Team Up to Develop KF-X Engine Parts

Imagem
Hanwha Techwin CEO Shin Hyun-woo (right) shakes hands with Jean Lydon-Rodgers, general manager of GE Aviation's military systems, after signing the partnership for the KF-X at the Farnborough International Airshow held in the U.K. on July 12 (local time).
SEOUL, KOREA
14 July 2016 -

Hanwha Techwin, a defense unit of Hanwha Group, has teamed up with U.S.-based GE Aviation, one of the world’s top three aircraft engine suppliers, to jointly develop engine parts for Korea’s flight-jet development project KF-X.

The company announced on July 13 that it has signed the partnership deal with GE at the Farnborough International Airshow held in the U.K. on the 12th (local time). The aircraft engine production industry has high barriers to entry. Currently, GE, Pratt & Whitney and Rolls-Royce are considered the world’s top three aircraft engine producers.

Hanwha Techwin said, “With the latest deal, we are now able to lead the integration and installation of the engines into the KF-X jets and domestically assemble and produce the engines and major parts. Based on these, we can also support flight test smoothly during the system development period.”

GE suggested “F414-GE-400” as the engine for the KF-X jets and was selected as the preferred bidder for the project in May. The engine has with 21,500 pounds of thrust and the KF-X is a twin-engine jet. Hanwha Techwin will receive the engine, which is designed and manufactured by GE, and assemble it. It will also produce and supply major parts and localize the technology to install and operate the engine into fighter jets.

The KF-X project is the largest defense project in South Korean history to develop Korean fighter jets replacing its aged fleet of F-4 and F-5 fighters. It is expected to be completed by 2026. Korea Aerospace Industries (KAI) manages the project and Hanwha Techwin is in charge of developing the engines. The size of the KF-X engine business will be worth more than 4 trillion won (US$3.49 billion) – 300 billion won (US$261.67 million) for the system development, 1.8 trillion won (US$1.57 billion) for shipments of mass production and 2 trillion won (US$1.74 billion) for exports and follow-up support projects.

Hanwha Techwin is a major engine supplier of various Korean fighter jets and helicopters. With the technical partnership with GE in 1980, the company began production of the engines for the F-5 jets and was selected as the final assembly company for the KF-16 jets in 1986.

Hanwha Thales selected to develop AESA radar for Korean fighter aircraft

Jon Grevatt, Bangkok - IHS Jane's Defence Industry
22 April 2016

South Korea's Defense Acquisition Program Administration (DAPA) has selected Hanwha Thales to develop an active electronically scanned array (AESA) radar for the proposed Korean Fighter Experimental (KFX) aircraft.

DAPA said on 20 April that it had selected the company as preferred tenderer for the AESA radar development programme and will now enter negotiations with a view to signing a contract by June.

Once under contract Hanwha Thales will develop the radar in collaboration with DAPA's Agency for Defense Development and KFX prime contractor Korea Aerospace Industries (KAI).

Samsung Thales was in competition for the AESA development programme with LIG Nex1.

Korea, US meet on fighter jet project
By Jun Ji-hye

Korea and the United States held their first high-level talks in Washington, Tuesday, on the transfer of jet technologies for Seoul's project to develop its own fighter jets.

The Ministry of National Defense said the two sides discussed the vital intersection of foreign and national security policies on defense technology cooperation, including issues related to the transfer of technologies for the KF-X project.

It was the first high-level meeting of the Defense Technology Strategy & Cooperation Group (DTSCG), which followed the group's working-level talks held in March. The DTSCG was established last year based on an agreement between defense chiefs of the two nations.

During Tuesday's meeting, the Korea delegation, led by Vice Defense Minister Hwang In-mo and Deputy Foreign Minister for Economic Affairs Lee Tae-ho, stressed the need for the transfer of key technologies from the United States for the success of the KF-X project, according to a ministry official.

In response, the U.S. delegation, led by David Shear, assistant secretary of defense for Asian and Pacific security affairs, and Rose Gottemoeller, undersecretary of state for arms control and international security, said the two sides will continue to discuss the issue, the official said.

The official added that details about which technologies will be transferred were not determined during the meeting.

The joint press release of the two sides also said, "The U.S. delegation provided an overview of its conventional arms transfer and regional defense trade policies."

The release added that the two sides concurred on the need for regular information-sharing on relevant issues and decided to continue to utilize the DTSCG to advance policy and strategic discussions on technology security, foreign policy and defense technology cooperation in support of the ROK-U.S. alliance.

The 8.5 trillion won KF-X project is to replace the Air Force's aging fleet of F-4s and F-5s. The government will invest an additional 10 trillion won to produce 120 jets by 2032.

The project is proceeding with the help of the U.S. defense company, Lockheed Martin, which vowed to transfer technologies used in the F-35 stealth fighter in return for Korea's purchase of 40 F-35s, signed in September of 2014.

In early December, the U.S. government approved the transfer of 21 technologies in a "large frame," according to the Defense Acquisition Program Administration (DAPA).

Since then, negotiations between DAPA and Lockheed Martin officials have been ongoing to list the details, as hundreds of technical items are part of 21 technologies.

Before its official kickoff in January, the KF-X project had suffered a severe crisis after the U.S. government refused in April of last year to allow the defense firm to hand over four core technologies — the active electronically scanned array radar, electronic optics targeting pod, the infrared search and radio frequency jammer and the infrared search and tracking system.

The DAPA said the nation will domestically develop those four technologies.

During the meeting, the Korea delegation also asked the United States to give it technologies related to the development of the medium-altitude unmanned aerial vehicle (MUAV), the official said. Washington said that was being considered added.

The two sides plan to hold the next DTSCG high-level talks in 2017, according to officials.

On the sidelines of the defense talks, Hwang met Deputy Secretary of Defense Robert O. Work to discuss views on extended efforts between the two allies to cope with ever-growing nuclear and military threats from North Korea, according to the ministry.

E a novela continua, dentro das 21 tecnologias básicas as negociações se expandem a mais de 100 itens diferentes... e ainda estão pedindo mais coisas que não tem nada a ver com o projeto KFX para UAVs
