It's actually got better range than what we're using now, legacy Hornets, when you compare the two with typical drop tank loadouts, the Gripen has an advantage in range, and the newest Gripen E will have an even greater range, which is what we would buy most likely if a Gripen purchase happens. I do agree though there are far better options out there in terms of range/interceptor like the F15S/SE/Etc variants and such. In terms of overall cost/capability ratio though, the Gripen is pretty good.
The OP airshow video has a couple US Navy aggressor dogfights spliced in, you can see a few times where Hornets are in the gunsights, and one with a warbling Aim9 seeker locking up a Hornet in the hud video. Such a great video and performance, I've never seen one of the aggressor squads performing at an airshow, especially with a 4 ship up like that. At 3:30 in the video, the split S at low altitude - fantastic, one of the better shots I've seen in recent fighter gopro vids.
