The largest hangar is only 75m wide, accounting into doors and what not the largest aircraft you could fit inside realistically is going to be only 65-70m wide. It's more likely they are used for more mundane uses like solar powered aircraft.
What kind of solar-powered (unmanned) aircraft would require a 75-meter wide hangar that is of military nature?
Perhaps that's meant to fit two (or more) smaller aircrafts parked side-by-side inside the hangar? Or whether that structure is actually a hangar to begin with?
