If what makes a plane "Generation 5" being the computer(s)
It's not, it's the stealth bit that makes it 5th gen, you can have all the computers and data links in 4th gen too; they have it now!
So I don't know how the JSF system is supposed to be better and obviously, for it to work, other aircraft need to be equipped too.
The main use for it obviously is that is allows any (not just stealth) fighters to keep their radars off and not present a huge target while still seeing the enemy on their screens, courtesy of an AWACS broadcasting this to them.
Now all we need is a boutique war for it to shine.
How about no war at all, that would be even better!
