Sweden entering NATO could be the beginning of Sweden selling planes to NATO.

I don't think there is much demand for JAS Gripen in Nato countries at this day. 4th gen fighters do not have much lifetime left in them, and F35 is increasingly taking the role of the current-gen fighter for advanced nations.

But Sweden is already member of the Cuture Combat Air System (FCAS) initiative to create a 6th gen air war system of systems, alongside nato members. And this kind of colaboration will be even more natural when/if they join Nato.

Dunno. If it was something else, I'd be tempted to agree. But Sweden deciding to join NATO, everyone but Hungary agreeing, Sweden stopping parts? Not sure. It's a, well, minor act of military... aggression? Extreme unhelpfulness for sure.

Also the real question would be, would Hungary see it as a credible threat. Were they to go ahead with that, they'd find themselves with no airforce and unhappy allies. That sounds like a raise they couldn't afford to raise.
