He spent the whole time talking about situational awareness with about 10 seconds on stealth being the way to give you that information sooner than your opponent would get it. So one question that I wonder about is whether a UCAV would be a cheaper way to "spice up your legacy aircraft" rather than an F-35 by giving them the information they need.
Another thing that I wonder about is: hasn't the Gripen had this sort of thing for ages?
