Further elaboration:International Herald Tribune wrote:TOKYO: 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, a news report said Saturday.
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 — fitted with a domestic engine, 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 multibillion-yen (multimillion-dollar; multimillion-euro) project means developers will start working toward flight tests, with production in about 10 years, it said.
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.
An official on duty at the ministry on Saturday said he was unaware of the project. He refused to give his name, citing policy.
Japan's air force has been searching for replacements for its aging fleet of F-4s and F-15s. 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, 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.
On Friday, Japan and the U.S. 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.
Given the events of WWII, it seems that Japan might be testing it's "self-defense" limits a bit far - but what do you think the implications are of a Japanese-built stealth fighter, apparently deliberately designed to be a competitor for the American F-22 Raptor?Aviationweek blog wrote: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.
(The only reason this was posted here and not in HAB as this is a fighter, and doesn't quite qualify as "heavy." Besides, the sociological implications of this range much further than merely technology.)
