Real hard to get a heavy flying wing on board a carrier. That's probably the bottom line. Launching without tail surfaces might be exciting, too. J-UCAS died in 06 , so the X-45 and X-47 were orphaned. The Navy opted to go with NG for their UCAS program. There may have been something about the handling characteristics that weren't encouraging, or Boeing didn't think it matched well/best with whatever the UCLASS requirements were at a given moment. Or that it would require more development time/cost. Or some combination of those.
The interesting bit to me is that Boeing either spent their own money early, or used the post PDR money to build hardware. Makes me wonder if there aren't three other PDR airframes out there collecting dust.
