I don't disagree with the questions about generations.
5th gen is generally stealth capability, and advanced avionics/sensors.
6th gen is stealth, optionally manned.
But I'd argue my own definitions.
1st gen jets are from WW2 (Meteor, Me262, P-80...), and peaking with the likes of the F-86, Mig17, A-4, etc. They are subsonic early fighters.
2nd gen would be mach 1 capable, after burning engines. Radar and Missile capable. F-4, Mig21, F-100, etc.
3rd gen would be energy maneuverability multirole fighters (F-14, F-15, F-16, F-18, Mig29, Su-27, etc.).
4th gen would be stealth capable, super cruising, etc.
There are of course execptions to these, and those could be described as their lowest most applicable category. Electric Lighnting was supercruise, but not 4th gen. F-4 was multirole, but not 3rd gen. Mig17 was afterburning, but not 2nd gen, etc.

@dammy "I'm talking about US program, not PLA's." then your argument is even WORSE. The US has no carriers to shoot hypersonics at. We can sink enemy ships with ease using a variety of other better weapons. The US is not investing heavily in hypersonic glide weapons as this video pointed out. the US is the world leader in all forms of hypersonic research, and they understood back in teh cold war the limitations and economics of hypersonics. everyone else is still playing catchup.
So, since the US has no such weapons, as we have no need for them and they don't make sense strategically nor tactically, we are going to discuss the PLA's hypersonics as the use case you KEEP describing is that of China attacking a US carrier. and since china actually tested one of these for real, we have actual understanding of what it can and cannot do right now.
The Chinese test missed a known stationary target by many miles. Two, as hypersonics descend into thicker air near the surface (where carriers are), they can no longer achieve hypersonic speeds due to air resistance. Look at the max speed of different aircraft at sea level vs at 40k ft. Many jet fighters can't even go supersonic at see level due to air density. Gliders have a fixed energy budget to use to reach their target. If you bleed off too much enroute, you wont have the same range as a missile that has nothing to dodge. Also, at mach 5 to mach 10, the exterior frictional heating will destroy sensors, antennae, etc. (look up the X-15 fastest flights if you don't beleive me). and so how do you plan to communicate with this thing in flight? The plasma build up during reentry of a space capsule can happen to these hypersonics too, blocking communications as well. How do they track moving targets after they've been fired? Keep in mind they are firing beyond line of sight, and so early the only way they can be guided is to be told by ground assets where the target is and where teh interceptor missiles are. These things can be detected and tracked from the point of launch, giving time for even a large ship to maneuver enough. And since the missile will be supersonic at best by the time it reaches the target, the majority of the damage will have to be done by it's rather small conventional warhead.
Also, don't forget that the US has demonstrated multiple weapon systems capable of intercepting ICBMs, satellites, and objects moving at hypersonic velocities in live tests. These hypersonics may be fast, but they are still much slower than a SpaceX Falcon 9 rocket.

US has the B-21, B-2, F-35, F-22, NGAD, etc.
Even as other nations like Russia, China, South Korea, UK, and others seek to field their own stealth aircraft, the US's most obsolete stealth aircraft from the 1980s are still stealthier than anything these other nations have yet been able to produce....says a lot about just how far behind everyone else is.
Tacit Blue, Have Blue, Bird of Prey, YF-23, YF-32, F-117, SR-71, various stealth drones, Loyal Wingman, Ghost Bat, AH-66, stealth UH-60, DDG-1000, Sea Shadow, etc. US has a long history of stealth aircraft and stealth technology, both in research as well as operationally.
