Since the mid-1950s, Japan has obtained patents for American F-86 fighter, T-33 jet trainer, F- 104J fighter, F-4EJ fighter and F- 15J fighter, as well as military helicopters such as SH-60, CH-47H and UH-60J/JA. Patented military aero-engines include: TF40 (equipped with T-2 advanced trainer and F- 1 support fighter), J79 (equipped with F-4EJ, F 104J, F- 104DJ fighter) and F 100 (equipped with F) T64 (equipped with P-2J antisubmarine aircraft, PS- 1 antisubmarine seaplane and US- 1 amphibious rescue aircraft), F10 (equipped with F-2 support fighter).
Military and civil aviation technology research cooperation
On the military side, according to the "Guidelines for Defense Cooperation" constantly adjusted by Japan and the United States, Japan actively studies advanced military equipment with the United States, and strives for the equipment system of the Japanese Self-Defense Force and the US military to be more universal and enhance its military strength. See table 1 for the open aviation-related military projects jointly developed by Japan and the United States.
On the civil side, in August 2005, Japan and France signed a joint research agreement on supersonic passenger aircraft technology, hoping to make a breakthrough in the field of supersonic passenger aircraft and take the lead.

International Cooperation and Development of Fighters
1988 the United States and Japan jointly designed the F-2 support fighter. It is the successor of the F- 1 support fighter based on F- 16, which combines the advanced aviation technology of the United States and Japan.
International cooperative development of civil aviation products
1958, the Japanese government promulgated the Aviation Industry Revitalization Law, which supported the development of YS-1/regional aircraft from policy and economy. YS- 1 1 was put into use on 1965, 1974 stopped production in February, and * * * produced 182 aircraft, with a loss of 36 billion yen. After YS- 1 1 failed in the international market competition, Japan re-examined its aviation industry development strategy. It is recognized that: firstly, although some advanced manufacturing technologies have been mastered in production through imitation for many years and the industrial base has been greatly restored, the technical base of new aircraft (aircraft and engines) is relatively weak, especially in integration and comprehensive management, market forecasting, after-sales service, etc., and there is still a considerable gap with the world advanced level; Second, after the mid-1970s, some aviation industry enterprises have accumulated experience in cooperative development with foreign aviation industry enterprises. In the 1980s, the Japanese government listed the aviation industry as one of the emerging industries and wanted to develop the civil aviation industry. Third, international cooperative development has become a trend, and developing the whole machine independently is costly and risky. Therefore, in 1986, the former Ministry of International Trade and Industry promulgated the revised Aviation Industry Revitalization Law, which changed the localization of independent development into international cooperative development, and set up the Aircraft International Cooperative Development Promotion Fund (IADF) to provide subsidies for international cooperative development projects. The new subsidy system retains the original subsidy part, increases the interest subsidy, allows the project responsible unit to borrow money from the Japanese policy investment bank of the government system, and IADF gives interest subsidy.
Up to now, including Boeing 787, Japan has participated in the subcontracting, cooperative development and production of international aviation parts for 29 types of aircraft, 20 types of engines and airborne equipment. Among them, 36 aircraft and engine parts invested in venture cooperative development projects, with an investment ratio of 1%? 35% varies.
