Here’s a short news report on the program to domestically develop the Japanese military’s next fighter:

After being repeatedly turned down by the US Congress in its attempts to purchase the F-22, the Japanese government has turned to its own stealth fighter program. As the video shows, they seem to be making significant progress in the development of the “Shinshin” fighter [with a little help from France], but it will take years to produce a final product. For more information, check out Aviation Week’s post on the ATD-X.

Mitsubishi Stealth
The Mitsubishi 3000GT sports car was sold in the US as the Dodge Stealth, but now the company has moved up to the real thing.

Japan's Technical Research & Development Institute (TRDI) recently unveiled images of the Mitsubishi ATD-X stealth fighter in the form of a full-scale radar cross-section (RCS) model. One picture was released a few months ago by TRDI, but has now disappeared from their site. Other images can be found here. They include a presentation slide confirming that France has been supporting the Japanese stealth program:  between September and November 2005, the model was tested in the French government's radar cross-section (RCS) range. Other features of the twin-engine jet include thrust vectoring with external paddles, an F-22-like external shape, fly-by-light controls and the testing of a smart-skin sensor.

In some ways the ATD-X project is comparable to BAE Systems' Replica stealth demonstration in the mid-1990s. It's not likely that the Japanese government will fund the development of an operational stealth fighter, but the domestic capability may be used to ease US concerns about exporting its own stealth aircraft to Japan. Further down the road, too, the same technology could be used in other systems such as cruise missiles or unmanned air vehicles.

Using the French range is logical. At Bruz, near Rennes, France's DGA defense agency's CELAR (center for military electronics) laboratory constructed the Solange indoor RCS range. A photo found here shows that Solange may be the biggest indoor RCS range in the world, capable of measuring a real fighter rather than a subscale mock-up. The same site also confirms that Solange was built with the help of a US company, absorber specialist Emerson & Cuming.

justement le projet ATD-X est 100% japonais, pour répondre au refus américain de vendre le F-22 au japon en 2007. le ATD-X a toute les chance de voir le jour rapidement grâce à la maîtrise japonaise des technologies de pointe nécessaire au développement d'un chasseur de 5th génération, n'oublie pas que les japonais étaent les premier à développer un radar AESA dans le cadre du prjet FS-X/F-2.

Report: Japan to develop prototype fighter jet

Published: July 24, 2007

TOKYO: Japan plans to develop a prototype of an advanced fighter jet in the hope it will spur the United States to review a ban on selling F-22 fighters, a news report said Tuesday.

But an official of the Defense Ministry said no decision has been reached.

Japan's largest daily, The Yomiuri, said the Defense Ministry plans to request a budget for the next year to build the test model of a stealth fighter jet.

The project is expected to cost billions of yen (hundreds of millions of dollars and euros) over the next 10 years, the report said, without saying where it got its information.

It would be the first time since the 1970s that Japan has developed its own fighters, although the Yomiuri said developing the prototype would not necessarily lead to the actual development of stealth jets.

Japan's agreement with the U.S. to jointly produce F-2 fighter jets ends in 2011, and Tokyo wants to build on the technology base achieved during that relationship, the paper said.

Japan has expressed interest in advanced F-22 fighters. However, the U.S. Congress has repeatedly banned the sale or license of the F-22 "Raptor" to any foreign government, largely to safeguard its advanced technology.

The latest attempt to repeal that ban was shot down in the U.S. Senate earlier this year.

A Defense Ministry spokesman said the ministry has been studying stealth fighters but has not begun considering building a prototype. He also said no decision has been reached regarding the budget request as reported by Yomiuri. The spokesman spoke on condition of anonymity, citing protocol.

The F-22 was originally designed by the U.S. to counter the threat of advanced Soviet Su-27 fighters during the 1980s.

Though that threat has diminished, Japan now is seeking to counter a Chinese fleet of those same fighters.

Yomiuri said by showing interest in building its own fighters, Japan apparently hopes the U.S. might review the current ban and cut prices of the F-22, which costs US$130 million (€94.06 million) a plane.

The report said it is not certain developing the prototype would lead to developing stealth fighter jets in Japan.

Mitsubishi ATD-X ShinShin a Japanese Stealth Fighter

The Mitsubishi ATD-X Shinshin is a Japanese aircraft being developed by the Ministry of Defense Technical Research and Development Institute (TRDI) for research purposes. ATD-X is an acronym which represents "Advanced Technology Demonstrator - X". The aircraft's Japanese name is 心神 (shin-shin) which means "one's mind". The main contractor is Mitsubishi Heavy Industries. This aircraft will be used as a technology demonstrator and research prototype to determine whether domestic advanced technologies for a fifth generation fighter aircraft are viable. The aircraft's first flight is scheduled for 2014.

The design of the aircraft reflects those of several American fourth and fifth generation fighters, most notably the F-22.

The aircraft also features 3D thrust vectoring with 3 paddles on each engine nozzle. The nozzles on the prototype appears to be uncovered and might have a slight adverse effect on the aircraft's stealth characteristics. Japan is set to develop its own next-generation stealth fighter jets to reduce its dependence on foreign technology and counter similar moves by China and Russia.

Japan, which wants to replace its aging fighter fleet, has also made overtures to Washington on the possibility of purchasing the U.S. F-22 Raptor stealth fighter.

However, the U.S. Congress has repeatedly banned the sale of the plane to any foreign government, in an attempt to safeguard the country's advanced technology.

Japan's Defense Ministry now aims to test its own prototype stealth jet, advanced control system and radar-jamming device — within five years, the Tokyo Shimbun newspaper reported, citing a budget plan submitted Friday by the ministry.

A mock-up has already undergone preliminary ground tests in France, the report said. Friday's decision by the ministry to push ahead with the multi billion-yen (multi million-dollar; multi million-euro) project means developers will start working toward flight tests, with production in about 10 years, it said. The reports also say that there was a possible involvement of US Lockheed Martin in the development of ATD-X.

Japan hopes that having its own domestic stealth fighter jet would mean it would not have to rely on foreign governments for key military technology, the report said.

Homegrown stealth capabilities would also likely help Japan enhance its radar systems to counter regional rivals China and Russia, which are thought to be developing their own stealth jets, the paper said.

Japan's air force has been searching for replacements for its aging fleet of F-4s. Options include three U.S.-made planes — the F-35 Joint Strike Fighter, the F-18 and advanced F-15s — as well as the Eurofighter Typhoon.

But a purchase from Washington has been hindered by its export ban of F-22s, imposed in part over reluctance to share sensitive military technology with foreign governments.

Japanese navy computers' recent leak of data from a joint U.S.-Japan AEGIS radar system has also spurred U.S. concerns over sharing information with Tokyo.

Japan and the U.S. recently signed a military data protection pact that tightens controls on the handling of classified information from one another's militaries.

The moves come as Japanese Prime Minister Shinzo Abe seeks to bolster the country's defense coordination with the U.S.

Washington has about 50,000 troops based in Japan, its top ally in Asia, under a mutual security pact.

Dommage qu'il s'agisse seulement d'une maquette...

les japonais n'ont ni les moyens finaciers ni la volonter politique pour aller de l'avant dans leur projet, ce qu'is veulent c'est le raptor, et rien que le raptor.

Pas moyen, Raptor..
C'est la seconde puissance économique du monde.
C'est politique plutôt, les Etats unis ne veulent pas de concurrent...
Surtout avec des pays comme le Japon, qui pourrait être des concurrents sérieux, car il ne manque pas de moyen ni de matière grise..
Ils veulent garder le monopole les Américains

Dommage, pour nous autres clients.

c'est normal, le F-22 à été conçu pour assurer l'hégémonie de l'USAF...les japonais ne l'auront jamais mais ils essayent quand même...

Japan seeks foreign engines for stealth fighter prototypes
By Leithen Francis

Japan is looking to use foreign engines for the prototype aircraft needed for its fifth-generation fighter programme.

The ATD-X Shinshin programme is still in the study stage, but industry sources in Japan and overseas say Tokyo has issued a document to engine-makers seeking information and pricing on powerplants needed for two prototype aircraft.

Responses are due to be submitted by 10 May.

Japan is interested in engines in the 10,000-20,000lb thrust class (44-89kN), and has a long-list of candidates on which it is seeking information, the sources say.

These include the General Electric F404 used to power the Boeing F/A-18 Hornet, Snecma's M88-2 for the Dassault Rafale and Volvo Aero's RM12, integrated with the Saab Gripen. Its search even contains the Gas Turbine Research Establishment GTX-35VS Kaveri, still in development for India's Aeronautical Development Agency Tejas light combat aircraft.

Japan had wanted to buy Lockheed Martin's F-22 to meet its future fighter requirement, but the US government has barred exports of the type and agreed to halt production for the US Air Force. Tokyo has responded by vowing to develop its own fifth-generation fighter under the ATD-X programme.

Local engine-maker Ishikawajima-Harima Heavy Industries (IHI) has been assigned to develop the XF5-1 engine for the ATD-X. The move to source foreign engines for the prototypes could be part of efforts to give IHI more time and ensure that the overall programme remains on track.

Japan is also expected this year to issue a request for proposals for new fighters under its F-X programme. Aircraft in the running will include the F/A-18E/F Super Hornet, Eurofighter Typhoon, and Lockheed's F-35 Joint Strike Fighter.

Le M88-2 et le F404 n'ont pas suffisament de poussée pour répondre à la spécification japonaise de 89 Kn en AB, il me semble que c'est une spécification faite pour le F414 et EJ200 (respectivement moteur de Super Hornet et Typhoon), comme c'est le cas dans le projet Sud Coréen, où ces 2 moteurs sont favoris.

Mitsubishi Hvy Ind : MHI Begins Assembly of Full-scale Model for Advanced Technology Demonstrator Aircraft Project

03/28/2012 | 01:44am


Tokyo, March 28, 2012 - Mitsubishi Heavy Industries, Ltd. (MHI) today began assembly of a full-scale structural-testing model of an Advanced Technology Demonstrator (ATD). The ATD, which MHI is building under the contract with the Japan Ministry of Defense, will be used to prove the airworthiness of advanced technologies, including stealth capabilities and high maneuverability, for future Japanese fighters. With the commencement of assembly, the ATD project has now moved into the production phase.

To mark the beginning of assembly work, the "first rivet" ceremony was held earlier today at the Tobishima Plant of MHI's Nagoya Aerospace Systems Works in Aichi Prefecture. Among those attendees were Yoshitaka Akiyama, Director General of the Technical Research & Development Institute, the Japan Ministry of Defense; Haruhiko Kataoka, Japan Air Self-Defense Force Chief of Staff; and Takashi Kobayashi, Representative Director, Executive Vice President and Head of MHI's Aerospace Systems.

During the ceremony, an equipment mounting bracket was riveted to the bulkhead separating the fuel tank from the forward equipment bay in the mid fuselage, which houses electronic equipments. It marks the first step in the assembly of the ATD aircraft. This riveting was conducted for the full-scale static structural test model to be used to obtain strength data of the aircraft's basic structural elements and to verify the design of the ATD.

The ATD prototype project was launched in Japanese fiscal year 2009 (April 2009-March 2010) in the situation of next-generation fighter development programs in neighboring countries. Through flight tests of advanced technologies relating to stealth and high maneuverability, the project aims at the empirical research of the advanced fighter technologies and air defense systems that are capable of coping with the stealth fighters that may soon be deployed around Japan.

With the assembly of the full-scale static structural test model as the first step, the ATD project is on track to produce a flight test model that is expected to make its first flight in 2014. The project is slated for completion by the end of March 2017.

MHI is committed to playing a major role in Japanese defense industry going forward and will make every effort to see the ATD project through to a successful completion.

Japanese Stealth Demonstrator To Fly This Year


Speaking to the foreign affairs and defense committee of Japan’s upper house, defense minister Itsunori Onodera has confirmed that the Mitsubishi ATD-X (advanced technology demonstrator-experimental) future fighter demonstrator is on course to fly later this year, albeit with a slight delay. Originally to have been unveiled to the media in May, the ATD-X is now a few months behind schedule but should be revealed later this year, with a first flight to follow soon afterwards.

ATD-X is a project led by the defense ministry’s TRDI (Technical Research and Development Institute), with Mitsubishi as main contractor. The aim of the program is to build an experimental aircraft for evaluating the maturity and integration of advanced airframe and engine technologies for future fighters. The aircraft is also colloquially known as the “Shinshin” (spirit of the heart).

In late 2005 an ATD-X mock-up was used for radar cross-section tests at a range in France, and in the following year a one-fifth-scale radio-controlled model was built to test high-angle-of-attack controllability. Preliminary results from these trials led to a decision to proceed with a flying ATD-X demonstrator program in 2007, and a year later the mock-up was shown publicly for the first time at the Japan aero show.

It has been speculated that the project was initiated to apply pressure on the U.S. to sell the F-22 Raptor to Japan, although if true it was unsuccessful in that aim. However, it has subsequently evolved into a program that could lead to an indigenous sixth-generation fighter incorporating what is described as “I3” (informed, intelligent, instantaneous) technology. Among the technologies being explored are fly-by-light optic cable flight control, three-dimensional thrust vectoring and a “self-repair” flight control system that automatically recalibrates itself after failure or damage to the control surfaces.

Ishikawajima-Harima Heavy Industries (IHI) has developed the XF5-1 afterburning turbofan to power the ATD-X. The company has considerable engine expertise through a long history of licensed production of U.S. engines, and indigenous development of the F3 turbofan that powers the Kawasaki T-4 trainer. The XF5-1 has already undergone extensive testing.

The Japanese MOD has outlined a plan for an “F-3” fighter to replace Mitsubishi F-2s in Japan Air Self-Defense Force service in the late 2020s, and expects to make a decision in Fiscal Year 2018 as to whether to continue with an indigenous design or to proceed along a joint development path, as it did with the F-2 (an enlarged derivative of the Lockheed Martin F-16 airframe with Japanese systems). Flight-tests with ATD-X will validate whether Japanese technologies are mature enough to support a cost-efficient indigenous development program.

On dirait qu'ils se sont inspiré du design du F15, il ya pas mal de similitudes pour aboutir à ce résultat d'avion furtif   

il faut se rappeler que les "ailes du F22 Raptor" doivent beaucoup ,voir tout aux Japonais pour la conception (le moulage ) en une seul piece d'une aile,procédé vivement rapatrié aux states ....

Pour reprendre un des commentaires : This is the beginning of something big in the land of the rising sun.

Le programme japonais de chasseur furtif


16 novembre 2016/ Actualité Industrie et matériels



Cette semaine, le japon entreprendra la première campagne d’essais de son prototype d’avion furtif de cinquième génération, le X-2, après le succès du premier vol en avril dernier. Initié en 2007 avec le projet ATD-X, le japon est parvenu en une décennie à réaliser un avion de combat tout en composite.

Le refus par Washington d’exporter ses F-22 et les restrictions en termes de transferts technologiques, qui ont accompagné l’achat de 42 F-35 en 2011, ont poussé le Japon à lancer en juillet dernier un appel d’offres pour l’acquisition d’une centaine d’appareils de cinquième génération. L’issue de la compétition est attendue en 2018, pour un déploiement opérationnel en 2030.

Mais l’achat sur étagère de F-35 supplémentaires serait, selon les experts, peu probable, d’autant que l’industrie aéronautique japonaise a renoué contre toute attente avec sa grandeur passée. Shinmeywa a réalisé un hydravion dédié à la surveillance, Kawazaki a réalisé en parallèle et en un temps record non seulement un avion de transport tactique, le C-1, en remplacement des C-130, mais aussi un concurrent du P-8 Poseidon, le P-1.

C’est le géant de l’industrie de défense, MHI, qui a constitué un cluster de 200 sociétés pour réaliser le X-2. Mais les Japonais n’excellent pas seulement en tant que plateformistes, ils sont aussi de redoutables équipementiers. Le P-1 dispose, par exemple, de sonars, d’un radar de surveillance AESA, d’un système de missions et de moteurs japonais. L’analyse de leurs brevets démontre qu’ils bénéficient d’une avance considérable en matière de capteurs multifonctions qui seront communs aux antennes radars, radio, et de guerre électronique de future génération ou encore de câblage par fibres optiques pour accélérer le transfert des données et de moteurs à poussée vectorielle.

Une politique de remplacement des armements américains a permis à l’industrie japonaise de développer ses propres missiles air-air de courte et de moyenne portées ainsi qu’un missile de croisière antinavire. En revanche, la dépendance historique à l’égard des Etats-Unis n’a guère stimulé son ingénierie logicielle sur le traitement du signal, même si Melco a réalisé des progrès spectaculaires dans le domaine de la guerre électronique, grâce à l’achat par le Japon des pods Elint français Astac. C’est pour cette raison que la BITD japonaise cherche à multiplier les partenariats pour compléter ses savoir-faire.

Ce programme d’avion de cinquième génération constitue donc une réelle opportunité pour les équipementiers occidentaux. L’industrie japonaise n’est, certes, pas capable, à court terme, de réaliser seule un système d’armes complet, mais elle est totalement incontournable pour accéder à ce marché, en raison des sommes déjà investies, et de la nouvelle orientation stratégique japonaise.
