In a world with stealth aircrafts and hypersonic missiles, a fighter like Gripen-E looks non-sense, but it is possibly the last example of when a jet is made to obtain the max of aerodynamics, flight and maneuver capability. Modern war jets sacrifice a lot their flight capability trusting in their "invisibility", or just using a so powerful motor, that aircraft doesn't fly by aerodynamics, but just by thrust impulsion.
