  • Taiga unveils plans to develop the F-3 ENG, an English export version of the Shinden II.


  • June: Structural test craft ASF-X-0 is rolled out.[1]
  • August: The British government orders 60 F-3 ENGs.


  • May: The first CTOL variant, ASF-X-01 is rolled out.[1]
  • August: First flight of ASF-X-01. In-house testing at Taiga begins.[1]


  • February: The ASF-X-01 is sent to Japan's Ministry of Defense. Japan's Technology Research and Development Institute forms an internal testing group, the Provisional Assessment Team, composed of F-15J pilots from the Japan Air Self-Defense Force.
  • March: The Provisional Assessment Team begins testing the ASF-X-01.
  • April: Taiga's facility in Yokosuka conducts a Shinden II test flight, the first of over 1,200 to take place over the next four years.
  • The ASF-X-01 suffers light issues related to electricity and cracking. These issues are not deemed dangerous to the aircraft's flight; tests continue with no delay.


  • September: Production commences on the ASF-X-02 prototype. This airframe is the first Shinden II to feature the STOVL engines.
  • The Blatnoi group plots to bring down the Russian government. In preparation, militias in East Africa are provided weaponry and support to divert attention from their plans.
