EXCERPTS: . . . Instead, a scramjet is a better option. Scramjet stands for supersonic combustion ramjet, and they work in exactly the same way as a jet on a plane, except with no moving parts. In a typical jet a turbine compresses the incoming air, fuel is then injected and ignited, which then forces the air out of the jet, creating thrust. But a scramjet does away with the turbine. Instead, it uses the craft’s speed to ram air into the combustion chamber with sufficient pressure to get optimal combustion. This makes them far more efficient and powerful than an average jet.

This efficiency, combined with the fact they don’t need to carry their own oxygen supply, means that they can be built far smaller, far lighter and have a far greater range than an equivalent rocket. This makes them ideal for hypersonic missiles.

However, understanding how air flows through a scramjet at hypersonic speeds is incredibly difficult. So much so that even our best supercomputers struggle to model it accurately or find optimal designs. This results in even our best scramjet designs having a lot of losses and drag being inadvertently built into them, which lowers their speed and reduces range. This sub-optimal design is a weakness of our current hypersonic missiles.

[...] This is where NASA and Argonne come in. They have designed an AI that can use a scramjet’s CFD (computational fluid dynamics) testing results (this is how a computer models air flowing around or through an object) and use it to figure out how to optimize the design of a scramjet missle for high speeds and greater efficiency. This has already been shown to create brilliantly efficient and powerful designs in far less time than previous methods and could even produce novel new designs.

In other words, this AI could design a hypersonic missile that is far faster and with greater range than any other in the world, sending the US to the forefront of this military arms race. All they need to do is apply this incredible AI to the HAWC, load it up with explosives, and off they go.

[...] Putin appears to believe NATO and The West won’t use nuclear weapons so our old deterrent of mutually assured destruction, that contained Russian aggression since the end of the Second World War, appears to have lost it’s potency. But, if NATO is armed with an arsenal of hypersonic missiles that has enough range to hit any Russian target, our deterrent is renewed. Such a powerful, precise and indefensible weapon would decimate any army, let alone the unorganized Russian army. Make no mistake. This AI really could change the course of the war...

I think the author jumps the gun a bit. Nuclear weapons aren't suppose to be used as a tool to bully other nations to do your bidding. They are only really a "Last resort" when everything else has been exhausted and only if your nation is on the verge of extinction (e.g. being wiped out by a larger aggressor).

Sure they can wave them round, threaten to use them, but that's just it, it's only powerful as a threat while it's not being used.

Once one is unleashed, you can't put the genie back in the bottle.

It would be a bit like setting fire to a hornets nest in the middle of a field of hornet nets. Sure you might burn one down and make it impossible for it to directly retaliate, however indirectly every other hornet nest is going to respond to the pheromones given off from the one you attacked and they aren't going to be happy.

In other words people will lose their fear of the "potential" if it's already happened and fight back. (It becomes a rally call, a symbol of Martyrdom)

We (the majority of countries) can do enough damage with conventional weapons without the need for nuclear options, only extremists cling to the concept of them being something to covet.

So once the newfangled AI optimization gets incorporated, mere hyperbolic superlatives won't be sufficient to describe how much better the New Hypersonic Missiles will be compared to 'an average jet'!
Awesome. Of course the leapfrogging assumes foreign spies somehow won't have their 'traditional access' to the crucial technical details. That would be new.

Goes without saying Israel will automatically have it's 'traditional' exclusive exemption access to it all - free of cost to that militaristic apartheid regime of course.
