The picture shows the F-35A fighter aircraft imported from the United States by Japan.
Although this has reduced procurement costs, it has deprived Japans defense industry of the opportunity to participate in the production of fighter aircraft.
So far, the F-2 fighter has been developed jointly by Japan and the United States, while the F-4 and F-15 have accumulated a lot of fighter R&D technology through the way of franchise production. But in the production of F-35A, Japan is only responsible for the final assembly. Some members of the LDP said: Although it is only the final assembly, it has also contributed to the accumulation of technology and personnel training. In the future, there will be a gap in the research and development of fighter aircraft is the problem.
