Most important post about why Spain doesn't need F35, but could buy if they wanted.Spain doesn’t need fighter jets immediately like the east European countries. Spain is far away from any battlefields, like Poland or Türkiye.
I agree with @Sanchez about Spain could entertain the idea of Hürjet and Drones on Juan Carlos, but tbh I don't think Spain needs any naval fighterjets, if drones can fulfill 80% of the tasks of a manned fighterjets.
They are so far away from conflict zones and the refugee boats are the biggest issue they have.
