For years, the United States government asks its allies — Britain, Italy, the Netherlands, Turkey, Canada, Australia, Denmark, and Norway – to support the development of new radar-evading F-35 fighter jet. By now, Japan has also expressed interest in buying the F-35 fighter jet. The single-engine F-35, also known as the Joint Strike Fighter, is at the early stages of production in Lockheed Martin Corporation. According to the Japanese media, however, the US government is going to withhold F-35 fighter software code, which will not give any nations of American allies. The reason Japan wishes to purchase F-35 fighter jet is that F-35, which is 20-30 years advanced than the Chinese fighter jet, can compete with the Chinese J-10, the 3rd generation fighter jet.
