Are Austrian, Danish or Finnish variants included?

Bookmark currently has two versions of Draken for Prepar3D, the Swedish J 35J and the Austrian J-35OE. They are sold as separate products.

The Finnish versions of Draken were similar to the Swedish versions, although there are differences in cockpit instrumentation and armament. There may be a Finnish Bookmark Draken for Prepar3D in the future, but it is not on the roadmap at the moment.

There are no plans for a Danish version of Draken for Prepar3D and probably never will be. The Danish F-35 was very different in instrumentation and systems as well as structurally and aerodynamically, so this would be a separate project.
