Japan Aims To Launch F-3 Development In 2016-17 By Bradley Perrett Source: Aviation Week & Space Technology October 22, 2012
Sometime around 2030, if U.S. Air Force plans come to pass, a fighter that leaps ahead of Lockheed Martin F-22 and F-35 technology will enter U.S. service. At about the same time, if Japan's plans come to pass, a similarly advanced fighter will enter service on that side of the Pacific.
It might be the same fighter. Merging Japan's 2030s requirement into evolving U.S. plans for post-F-35 fighters seems to make great industrial sense. Japan plans to begin developing a homegrown fighter within five years, with the aim of beginning production under the designation F-3 around 2027. The defense ministry wants to lay the groundwork to go its own way by investing in stealth technology and building its own powerful fighter engine 0046名無しさん＠お腹いっぱい。2012/12/15(土) 10:22:58.20ID:fj3fkZlZ ●原文：日本は２０１６−１７年にＦ−３の開発に着手 その２
IHI Corp. is to develop a technology-demonstrator engine of 15 metric tons (33,000 lb.) thrust, according to an official document seen by Aviation Week.
Mitsubishi Heavy Industries is already building a small airframe technology demonstrator, the ATD-X Shinshin, which the ministry expects to test in the fiscal year beginning April 1, 2014. Mitsubishi Heavy is also very likely to build the F-3, which Japanese officials expect will carry a pilot.
Full-scale development would begin in 2016 or 2017 and the first prototype would fly in 2024-25, according to the ministry's plans. Series production is to begin in 2027 and the type would begin replacing Mitsubishi Heavy Industries F-2 strike fighters in the first half of the 2030s. In the second half of that decade it would begin replacing Boeing F-15Js. The F-15s are older but are likely to remain the mainstay of Japan's air-defense squadrons, with suitable upgrades (see following article). 0047名無しさん＠お腹いっぱい。2012/12/15(土) 10:23:29.19ID:fj3fkZlZ ●原文：日本は２０１６−１７年にＦ−３の開発に着手 その３
The power of the IHI demonstrator engine is surprising. It would generate 50% more thrust than the General Electric F414, two of which power the Boeing F/A-18E/F Super Hornet. The Super Hornet's thrust is not notably high for its empty mass, 14.6 tons (32,100 lb.),
A Japanese engine would not be needed if the F-3 program were merged into a U.S. fighter program, as industry executives suspect it will, since the U.S. would certainly supply its own powerplant. But by developing an engine, Japan will retain the freedom to power its own fighter should it not come to an agreement with the U.S. And even if it does, technology from the demonstrator might be useful to the U.S. 0048名無しさん＠お腹いっぱい。2012/12/15(土) 10:23:44.69ID:fj3fkZlZ ●原文：日本は２０１６−１７年にＦ−３の開発に着手 その４
Japanese participation in the next U.S. fighter program is now conceivable because Tokyo has relaxed its arms-export restrictions, which in the past have largely prevented its industry from working with foreign partners. The way is not entirely open for cooperation, however, since Japan might be reluctant to supply some countries that the U.S. sees as suitable customers.
Stealth technology is also a feature of the F-3 program, as it has been for the i3 Fighter. That, too, is probably a hedge against failure to cooperate with the U.S., which is unlikely to need much Japanese help in that area when it designs its next fighter.
Other work flagged for the i3 Fighter might be enticingly dangled under the Pentagon's nose, though. The Technical Research and Development Institute and industry are working on skin sensors, directed-energy weapons and advanced avionics. 0049名無しさん＠お腹いっぱい。2012/12/15(土) 10:24:13.06ID:fj3fkZlZ ●原文：日本は２０１６−１７年にＦ−３の開発に着手 最後
Arguing that neighboring countries?meaning China, South Korea and Russia?will have stealth fighters and longer-range missiles in the 2020s, the ministry is asking for \1.6 billion in fiscal 2013-16 to study integration of antennas into the skin of an aircraft, thereby helping to control radar reflections. The antennas would be those for electronic support measures, which listen to enemy transmissions, and electronic countermeasures (ECM), which jam and confuse them.
The ministry also wants to push ahead Japanese ECM technology, to preserve national independence in that area that was developed in building a system for the F-15. The ECM work must be part of what the ministry calls an “all-around surveillance and jamming system.” Japan is also looking for “reflection suppression” technology, apparently distinct from stealth shaping and materials. Details are unavailable. Results of this electro-magnetic work are to be assessed in 2019. 0050名無しさん＠お腹いっぱい。2012/12/15(土) 10:24:44.99ID:fj3fkZlZ ●原文：日本は２０１６−１７年にＦ−３の開発に着手 訳者コメント
