Hasegawa 64702 1/72 Ace Combat ASF-X Shinden II "Kei Nagase COLOR" Model Kit ASF-X Shinden II is a prototype fighter plane from the Assault Horizon universe. The machine was presented in that universe as a prototype of the later serial F-3 Shinden II fighter. In the Assault Horizon world, the development of ASF-X Shinden II goes back to the terrorist attacks of September 11, 2001, when the Japanese government decided to create an aircraft capable of providing the country of the Rising Sun with protection against such attacks. Development of the machine started in 2003 and the first flying prototypes were ready in 2018. It was characterized by an impressive maximum speed, great maneuverability, as well as VTOL (shortened take-off and landing) capabilities.
