The progress:
Standard version: ready to upload
Naval version: I still have to do some changes to the rear landing gear and armament, as well as making missiles
Third version: will be a pure fighter/interceptor with markings that resemble those on the planes from the soviet air base 1521
Here some pictures:

For the challenge announcement: I had the idea of making a war challenge that is a campaign for SP with individual missions and the like. I'll make it in September if enough people (at least 5) will definitely join the challenge.
