Rafale is smaller than the Super Bug, it's more in the legacy Bug class. That's why I think almost every pic I've seen of one in operation has had 3 massive fuel tanks underneath. Just like we're facing with our planes, the Rafale was built under a Cold War design philosophy. In modern ops it's being forced to do things differently from the way the designers conceived it.
Of course, there are some odd configs for planes out there. You'll have older planes upgraded with newer avionics than the newer planes have! There are F-15s that are 20 yrs old with better radars than 5 yr old Super Hornets.
I believe "stealth" is listed as a requirement for a "5th gen" fighter, but how MUCH stealth isn't specified.
