I can't believe that after a long discussion on the 1.98ata K-4 that this a/c was included. I am truly disappointed that the developers were taken in by the private lobbying of a certain Hungarian, well known for his revisionism.

So what ?
Servers will allow it or not, and you can choose your server.
Most probably Tempests will have a rocket loadout as an option and it's even less historical.
If no server allow his toy, at least he will be able to enjoy it offline.
And if it is allowed on a server, I doubt it will make much difference on the gameplay I see there. 1.98 ata vulchers will still be bounced by some other guys they didn't see in the 10km bubble before diving.
