NITPICK: GRIPEN PYLONS
Even "clean" the Gripen's sleek lines are interrupted by pylons. Pylons on each wingtip. Two more pylons underneath each wing. Another pylon midline bottom fuselage. Another pylon opposite the (partially exposed) Mauser cannon. Pylons everywhere.
Everything just sort of... Dangles there.
This is not a problem with a relatively light load. A few air-to-air missiles and a couple of external tanks do not sully the looks too much.
Things get dirty when equipping the Gripen for a strike mission. A targeting pod literally sticks out like a sore thumb in its special station opposite the cannon. Add a few bombs, some fuel tanks, and self-defence missiles and the Gripen starts looking absolutely ungainly.
When Saab went about upgrading the Gripen to the JAS 39E, they redesigned the wings and fuselage to make room for more fuel and weapons. So what did Saab do with all that extra space?
They added two more pylons.
Unfortunately, those pylons were added to the fuselage, just outboard of the midline pylon. This presents a slight problem when carrying larger ordinance; as demonstrated in the picture above.
There is not enough room to use all three pylons!
This begs the question: Why bother in the first place?
Realistically, no matter what kind of combat mission is intended to fly, its minimum load-out would require two IR-guided WVR missiles (ie. Sidewinders) and two radar-guided BVR missiles (AMRAAM or Meteor). Saab could have taken advantage of the "NG" Gripen's redesign to reflect this fact.
Take a gander at the Gripen E mock-up above. Imagine if those two outboard Meteors were tucked into the fuselage similar to this Eurofighter Typhoon.
