Sorry but the USA does not have hyper sonic missiles yet.
Many of the challenges of hypersonic flight, such as the cumulative effects of extreme aerodynamic heating as glide vehicles speed through the atmosphere, become increasingly intractable as range and flight time increase. With long-range performance proving elusive, the Pentagon has shifted the offi

The US successfully tested a hypersonic missile in mid-March but kept it quiet for two weeks to avoid escalating tensions with Russia as President Joe Biden was about to travel to Europe, according to a defense official familiar with the matter.

And cruise missiles (far too slow) are primarily only useful against underdogs.
yeah sure, the Tomahawk devastated the Iraqi IADS of ODS, on of the most dense and sophisticated IADS in the world at the time.
So here's some counterpoint in regards to cruise missile being underdogs:
land/sea based sensors are line of sight (LOS) limited, low flying cruise missile are just as hard to intercept as high and fast flying projectiles, at best you only have seconds before onboard sensors could pick an incoming cruise missile as it appears out of nowhere, yeah so much so for being underdogs.
being slow is actually one of the advantage of a cruise missile, not a weakness themselves. Fire solutions on the missile corresponds with the time and thereby speed. The greater the speed, the greater the demand on the sensor/guidance integration to have a no-miss first pass solution.
Hypersonic missile body shape are designed to reduce drag coefficient, hence most of those missiles has a very small nosecone, some are even flat, not great at all to accommodate sensors. the smaller the volume, the more limited the sweep of the sensors are, and because it is faster, they have little time to discriminate objects, now add countermeasures and poof.
Just how hard is it to hit a moving object while being high and fast, make you own conclusion
also the recent sinking of the Moskva involves Neptune sub sonic cruise missile, the JASSM and its anti shipping variant the LRASM are a quantum leap ahead of those Neptune. the LRASM has AI integrated into it.
The likely hood of a B-52 making it towards China is more like 0,
True they're not making it towards China, their payloads will. The JASSM in its baseline variant is +370km, the JASSM ER 925km and the XR is close to 2000km. Flying from Alaska, Diego Garcia and launching it from the relative safety of Japan and the Indian ocean.
the B-1 wouldn't fare much better
and the B-2 aren't enough to provide a winning factor.
An AGM-158 JASSM has only an effective range of 350-400km, JASSM-ER range around 900km and even the JASSM-XR with a range of around 2000km isn't expected to enter service before 2024. The best part is that both the JASSM-ER and XR don't fit into the internal weapon-bay of the F-35. All of them are sub-sonic so good luck to them penetrating China's air-defense.
First of all, they occupy different roles, non VLO platforms like the B-1 or B-52 uses what is called a stand off weapons, lobbing long range missile in the relative safety out of enemy air defense. This will likely be used against targets ranging from PLAN ships, Chinese islands facilities in the SCS to blind Chinese surveillance and knock out Chinese A2/AD in the SCS.
A strike deep inside China would require what is called a stand in strike, this where the VLO (very low observable) B-2 and the upcoming ELO (extremely low observable) B-21 raiders shine. A stand in strike means the platform are deep inside the very bubble of enemy air defense, once they're there, they will lob cheap JDAM to devastating effect and run away undetected. This is how the F-117 are utilized in the opening days of Desert Storm. Meaning these will likely be used against Chinese industry, infrastructure (dams, power plant, bridge, shipyard etc) and anything that contributed to the Chinese war effort.
As for F-35 it is VLO enough, and China doesn't have anything close to its LO characteristics. And soon the F-35s will be equipped with the SiAW (Stand in Atttack Weapons), reportedly a modified AARGM-ER used for high speed stand in strike.
as the video suggest, it could be launched from the weapons bay or from the wing.
The B-1 will off course fare much better than the Xian H-6, the H-6 is actually closer to a P-8 Poseidon when it comes to weapons load and with inferior range and electronics. I think the P-8 is the underdog that no one really thinks much but deserve to be feared. Simply there are currently hundreds of those P-8 that could be turned into a quasi naval bomber, complicating Chinese effort in its defense.
