Better than the F-22 at what, being a fighter? I hope you’re right, but I think we would have heard about it.
I will say this friend, there are some things you really do NOT want to know about when it comes to “skunk works”.
The US has never relied upon a sole fighter aircraft, bomber or ship ever, as soon as it in production its already obsolete. We will make the best fighter aircraft but we will also make something that can defeat it in the case it falls into enemy hands.
