The FS9 version includes a complete Austrian J-35OE exterior/interior model, but the FSX and Prepar3D versions only contain the Swedish J 35J.
A J-35OE version for Prepar3D V4 is on the roadmap, but there is no timeplan yet.
The Danish F-35 is very different in instrumentation and systems as well as structurally and aerodynamically. There are no plans for a Danish version at this point.
