PICTURE & VIDEO: Mitsubishi/Lockheed F-2B crashes after take-off on test flight
By Barbara Cockburn
A Mitsubishi/Lockheed Martin F-2B on a test flight has crashed after take-off, causing it to slide along the ground as it exploded in flames, injuring two crew members.
The multi-role fighter was set to be delivered to the Japanese air force.
Video footage taken from a CCTV camera shows the aircraft taking off from a runway in Nagoya, before suddenly hitting the ground.
Mitsubishi says the flames were extinguished about 10 minutes after the crash and that the aircraft's crew, both company employees, were taken to a hospital with minor injuries.

ItÂ’s natural for people to reduce the fighter's RCS by taking some measurements but itÂ’s far from a stealth fighter. -
Don't know about the Japanese, but the Germans are doing it. Even the Taiwanese have done it on their AT-3 trainer.Originally posted by FG42:heard that most of the japs are very angry and disappointed over this incident after spending 12billion yen in this F-2 project. it was also reported that the americans were also very reluctant to share F-16 technologies with japan for this project. the americans prefer the japs to buy from them instead... recent ex-defense perm sec of JSDF's corruption scandal adds salt into the wound for the japs.

"EADS has developed modification packages for aircraft such as the Tornado, reducing radar cross section (RCS) by 10 dB, says Ritter. "More complex means" - including the replacement of some structural parts - can cut the RCS of a conventional-looking aircraft by 15 - 17 dB, which substantially reduces detection range and (to an even greater extent) boosts the performance of electronic jamming, because a hostile radar needs more power to see the weaker target through the jamming signal. EADS has even developed a package of RCS-reduction measures for the A400M transport, not to make it invisible but to make its towed radar decoy more effective. Interestingly, EADS estimates that the Super Hornet has an RCS 20 dB lower than the original F/A-18C/D, getting close to the values for aircraft like the F-22 and JSF."

Air force hesitates over imported stealth technology

PRESSURE: The military believes that new material makes aircraft unsafe, despite a complaint by the man who brought the technology to Taiwan
By Brian Hsu
STAFF REPORTER
Monday, Nov 10, 2003, Page 1
The air force has delayed plans to use new stealth technology introduced by an overseas Taiwanese man because the technology might not suit local needs, defense sources said yesterday.
The imported technology, based on dielectric radar absorbing materials, has been undergoing secret tests for the past two years in a project code-named "Black Leopard." The material is supposed to make any object it covers invisible to enemy radar.
But test results showed that while the stealth material worked, it added too much weight to planes. It was feared that the extra weight might affect safety and overall performance.
The hesitation sparked a strong reaction from the overseas Taiwan-ese who brought the stealth technology to Taiwan, a defense official said.
"This man is obviously very influential," the officials said. "Through special channels, he has made a complaint to President Chen Shui-bian (’Â�…�G). We do not know President Chen's response to it. We fear that the man will not easily give up," the official said.
The National Security Council plays a leading role in the Black Leopard project, while the air force and the state-run Aerospace Industrial Development Corporation (AIDC) are joint executors of the plan. The spending for the project is not known and it was not included in the annual budget of the Ministry of National Defense.
The AIDC provided an AT-3 jet trainer plane for the testing of the radar-absorbing material.
The AT-3 has made 43 test flights over the past two years, sources said. The stealth material was even applied to an air-to-air missile carried by the AT-3.
In test flights against an Indigenous Defense Fighter (IDF), the AT-3 was not detectable to the IDF at a distance of 35km, which means the IDF would not have had time to respond to a missile attack by the stealth plane.
Despite the favorable test results, however, the AT-3 was thought to be carrying too much weight.
"The test results were only for reference since they might not be realistic enough. But a realistic test might put the test pilot in danger, because it is not known whether the extra weight on the AT-3 would pose a risk," a defense source said.
"It is also questionable whether the stealth-capable AT-3 would be able to safely fire a missile as simulated in the tests," he said.

Thats true, they have spent an awful lot of time and money on this larger version F-16.Originally posted by FG42:heard that most of the japs are very angry and disappointed over this incident after spending 12billion yen in this F-2 project. it was also reported that the americans were also very reluctant to share F-16 technologies with japan for this project. the americans prefer the japs to buy from them instead... recent ex-defense perm sec of JSDF's corruption scandal adds salt into the wound for the japs.

Maybe they can spend the time and money buying and equipping the F-16s from US.
That being said, one must also take note that developing a combat aircraft even with the help from Lockheed Martin is not going to be easy. Having corruption and frequent changes in the government certainly won't help either. -
From Videos it showed that the nose went went up and was supposed to life off when it suddenly lost power and the tail of the plane dragged on the runway.

Erm, no, looking at the video you will realise that it contacted the ground with its nose down. In cases of engine failure on take off, the nose is supposed to be maintained in a climb attitude, at least in the case of a multi engine aircraft.. The F2, well, is single engine. What I gather happened was that the pilots detected a drop in take off thrust, speed was reducing fast, so he nose-down to regain the speed in a hope that the speed increase as a result will get him lifted off the ground. The generic F-16 has its center of gravity behind its center of lift, thus it does not nose down during lose of thrust. It has to be pilot input. It was however too short a time to decide to do the correct thing, which was to eject.Originally posted by kenn3th:From Videos it showed that the nose went went up and was supposed to life off when it suddenly lost power and the tail of the plane dragged on the runway.
