You are getting 6th generation carrier drones. The whole problem with the F-35 is that they are trying to get 3 different aircraft from one design, they could build the F-35A and maybe the F-35C from one design, but the F-35B is such a different aircraft it needs a whole new design.
The other part of it is probable fraud. Remember the A-12 fiasco? Word from OMB is that they are having issues "adapting the A-12" technology, among other issues. This was a giveaway. The OMB report early Summer said $650 billion, but it's been pushing up an average of $100-150 billion a year with no resolutions in sight. Everyone is afraid to touch it, or investigate it. I wouldn't be surprised if Granger was involved.
I believe they may be Japanese, a different country, but your geography may be better than mine. That or you're talking crap.
So, what you're saying is, a very professional and highly organised cyber attack was traced back to China. Yep, a load of (*)(*)(*)(*) and bull. If I were to do some serious hacking of military secrets, I'd do it from some island somewhere so, if anyone managed to trace me, I'd just ack up and leave before they could do anything about it. It's a lie or a guess, presumably to deflect attention from their terrible security.
When you are a Nation-State, you do not worry about such things as much. Aftr all, what will happen if you are caught? You just blame it on private individuals and claim innocence. Cyber-warfare is going on all the time, and who does it is no secret. Check around for examples of North Korean hackers going after South Korea, or in the ME against Israel. Pakistan is not going to declair war against India because "some hackers in India" break into their computers and download their war plans.
