Several years ago it was a big deal. Today... not so much. That's because back then the US assumed it would be first to then brag they have it. Before the J-20, stealth was invincible. After the J-20 all of the sudden stealth could be easily defeated. They exaggerate when they're the only ones to have it and then the "truth" comes out when they aren't the only ones. What they don't talk about which tells a lot is now all of the US and its allies are in range where before the range issue comforted them. They talk about how Aegis can knock this down. Are they going to spend the money to make enough Aegis ships to encircle the US? How about this satellite system they say they can put up to track hypersonic missiles? How about allies? Lots of money they don't have that will have to be spent.
