The F-5 35 generation fighter-bomber proposed by American developers did not meet the needs of the Japanese Air Force. They needed a maneuverable fighter to gain air superiority, not a cumbersome “cow.”
In this regard, the Japanese aircraft manufacturing corporations decided to create their own national generation 5-6 aircraft. And in April 2016, the first prototype called X-2 rises into the air. On this experimental aircraft it is planned to work out all the key technologies that will later be implemented in the projected X-3 fighter.
