Dug this up. No idea what the formulas and technojargons mean honestly.

If anyone thinks that's a Mach 6 platform, they're wrong. There are other reasons for the wing sweep. It reminds me of when the USAF first showed pics of the F-117 to intel people from a spysat perspective and due to the faceting and wing sweep they all thought it was a hypersonic aircraft. Rightly so, because a hypersonic aircraft would have those features, but they must have concealed it's size, as it was much too small to be a hypersonic vehicle.

θ-β-M relationship basically is the formula describing the relation between oblique shock angle, flow deflection angle and mach number. It could be used to do a very rough estimate of an airframe's top airspeed since generally as the post said you do not want the leading edge of the shockwave to interfere with the wings and control surfaces so you could find the angle between the nose and the edge of the wings to calculate how fast the plane needs to be going so the leading edge of the shockwave formed at the nose start interfering with the wings. But imo it is a very rough way of estimating top speed and there's a few specially designed aircraft that could operate beyond these restrictions so I personally wouldn't take it as solid facts.

Mach 2.5 is a pretty good speed.

After the first drawing of NGAD we saw a secpnd appear , some sort of light NGAD , may be the second will be the affordable one.

Are they still going with their "Digital century" series thing? or did they ditch it for something more conventional ie. a single manned NGAD design+CCAs

We absolutly don't know what the NGAD look like , we can just speculate with the few informations we have...

Kendall: Reveal of New Chinese Aircraft Hasn’t Changed USAF Plans

Secretive new Chinese stealth aircraft are already accounted for in the Air Force's NGAD plans, Secretary Frank Kendall said.

www.airandspaceforces.com

Asked what recommendation his blue-ribbon panel of stealth experts—including analysts, former Chiefs of Staff, and senior generals—came up with regarding NGAD, Kendall said they reached “a consensus that there are a number of other things that we need to fund” but if resources are available, “then it would still be beneficial to have an NGAD-like aircraft.”

Kendall could not go into detail because of classification, but said several alternatives were considered.

“We looked at something that’s more of a lower-cost, multi-role kind of a capability. We looked at something that’s more tailored to work with [Collaborative Combat Aircraft], although, of course, NGAD could do that. And we looked at some other ’out of the box’” ideas, he said, adding that “some of them might be worth pursuing independently.”

I haven't heard this said explicitly before. The consensus is that PCA is not the highest priority to fund. I assume "other things" refers to CCAs, NGAS, maybe NGAP, and potentially could be expanded to include entirely separate programs like Sentinel.

Well at this point, funding and focus are likely in flux until incoming administration officials make choices. There probably was a well defined plan, and some here have outlined it, but the program is an open question now.

NGAS (tanker) and NGAP (engine) are tied to manned NGAD. Sentinel is taking a lot of funding. CCA is not yet.

Sentinel is very not a priority it have zero need in a battle, nuclear weapons are a waste of money , Bomber and submarines are enough for launching nuclear weapon. This is not a sentinel missile who will stop the Chinese expansion, this end of the world weapons have realy no utility, insteed if we want a collective suicide. They are speaking a lot of Space weapons it seem to be a hurry now for this kind.
This is interesting :
"“What motivated us to take another look [at NGAD] was the affordability” Kendall said, noting that there were other missions to which the service wanted devote added resources such as “more aggressive counter-space capabilities, airbase protection, particularly our forward air bases.” Is there a hurry to fight in Space a new priority ?
"former Chiefs of Staff, and senior generals—came up with regarding NGAD, Kendall said they reached “a consensus that there are a number of other things that we need to fund”
What is more important to fund than a new fighter ?
And the last interesting too:
"And we looked at some other ’out of the box’” ideas, he said, adding that “some of them might be worth pursuing independently.”
