Smile. I took a History of Science class at Wheaton College. My professor was Dr. Joseph Spradley, who wrote some of the original mathematics and physics of phased array radar, the basis of the SPY/AEGIS system on the Burkes. He loaned me a copy of his paper, which was more like a half-inch thick book. It was full of integral calculus and other summation equations. Later, when I was in engineering school taking things like machine language and Fortran and Pascal, I recalled some of his text and saw how the phased array system lends itself very well to computer processing of its "pencil beam" orientation and the return signals obtained from the "painted" target. It doesn't need a rotating antenna, which seems rather primitive in comparison. The faster the processor and the greater the number of fixed antennas in the system, the higher the resolution of its "imagery" and the harder it is to jam. And there's no jamming it when it's not pointed at the jamming source. And even then, a jamming signal would need to cope with the system's ability to alter transmitted levels of energy that essentially encode the bandwidth of plausible return signals. As we know, the speed of computer processing has multiplied many times over the years, making phased array radar more potent than ever. Can it still find the target? Anything can break, but it's great when it does work. Fun question.

@Rob_F8F I would think the terminal guidance of an anti-ship missile would not be electronic, as powerful ship-based ECM should be assumed capable of thwarting any radar on the missile and any electronic remote guidance the closer the missile gets to the ship. I would think the terminal guidance would be processed signals from infrared and optical sensors. The higher quality of the processing, the likelier a hit. In that sense a hypersonic would seem to be moving too fast to process countermeasures and the movement of the ship. The terminal behavior of anti-ship missiles I have seen includes an evasive climb and dive to try to evade CIWS.

@D64nz I would think the problem with a hypersonic is that its target tracking can't keep up with it when faced with countermeasures. There's a sweet spot for the guidance system's processing capacity to filter out the likely counter-measures and track the ship. That means there's a sweet spot for an anti-ship missile's speed in the terminal phase. And the defense is always going to have a last second wrench to throw in the critical window between a hit and a miss. Hypersonic speed forces a very high guidance computer processing speed that might miss the final correction needed for a hit. Now if it's a nuke warhead that just needs proximity . . . that needed to be chasing a convincing decoy some distance away.

@Rob_F8F I don't know that hypersonic speed is an advantage if it cannot be accurate or defeat countermeasures.

The usual cities in rubble scenario?

I think surface ships will need their own horde of drones in the future. Maybe different sizes and types can be packed into launchable modules in VLS tubes. They would be used to further confound the terminal guidance systems of anti-ship missiles beyond the Burkes' and Ticonderogas' current EW and other capabilities. In a peer fight the incoming warheads could be nuclear. It will be critical to have a way to confound those guidance systems, because, as you know, all the missile needs to do is get close.

What specifically is the AI looking for? What does it use to process smoke and chaff and flares? Can the AI work through the Faraday cage it will need to avoid EMP effects (see Ukraine). I suppose if they spread out and talk to each other and the ship isn't too far away they could get some hits. How big are their warheads going to be?

The M10 does not appear to be built to counter what will be its nemesis, the FPV drone. Back to the drawing board. The design requirement is not so much to move infantry forward as to move one's own FPV drone controllers forward through mined areas to bring more enemy targets into FPV range, which appears to generally exceed the effective range of a tank gun, and to provide protection for that crew through electronic and other counter measures to thwart the enemy's FPV drones and mines. Think of it as a sort of aircraft carrier on land. The unit could involve more vehicles as does a carrier task force. Many vehicles would be almost purely for defense against enemy drones. They could launch balloons or quiet gliders to acoustically acquire enemy drones. They could forward fire land-based, networked listening devices in a role similar to the sonobuoy. Land assault is now a smaller version of the carrier task force rather than battleships (tanks). The idea is for the number and variety of one's own drones and control points to outnumber the enemy drones and control points. Mechanized artillery is still relevant because its range generally exceeds drone range, the naval analogy being missiles launched out of VLS's.

Adversaries, like the US, perform SIGINT missions to examine US systems. They know almost whatever the US Navy lets them see in operation. They just can't afford it in the volume we can, and they're usually behind us in the details. An AEGIS processor can have "gears" of speed and resolution that they have never seen before because the Navy never shifts into them where they might be examined. Cards to play. Secret sauce ready to go.

North Korea is in regime preservation mode, e.g. nuclear program. If China commences hostilities against Taiwan, South Korea goes into full alert, which probably deters North Korea. The question is would China prompt North Korea to take surprise offensive actions of some kind to begin a dilution of Allied forces. I doubt it. I suspect if North Korea is in on the war they start at the same time as China does in an attempt to overwhelm allied forces. Like Russia, this effort could evolve out of extensive military exercises by both countries. Like Russia, that would be the giveaway that the attack is coming. North Korea would be risking its regime while China could not devote itself to their preservation as they did in the Korean War. I think NK looks for arms deals with China to raise revenue. I don't think the NK regime risks losses in a fight with South Korea and US forces there. Deterrence has worked for decades.

Yes it does. But it gets into a sort of gray zone of stealing/reparation seizure confusion at sea.

Helicopters? Really? See Ukraine.

@tabinerdominguesmarques9715 With such confidence in China and North Korea, one would think Taiwan and South Korea would have been annexed long ago. Yet there they are, still autonomous. I know, change is just around the corner . . . or the next corner . . . or the . . . The fact is, the "crushing" has not happened. Why not? Lack of preparation? Fear of loss?

@WarriorsIntelect Yes. It is why they failed in earlier attempts and why they have not tried again. In the 50s they found out how difficult it was to invade Taiwan. The Chinese buildup is in large part a reassembly of Chinese dignity after humiliation. Psychopaths in the endless pursuit of victory and respect. A part of the populace gets caught up in that kind of thinking. Most folks want to live and let live. If we can get past Xi's generation of leadership without catastrophe, we might encounter a more businesslike and peaceful China. I have no hope for Russia. The psychopathic dictatorship style is firmly entrenched there. Too many of the people who could change that lose hope and leave for a better life elsewhere. The regime keeps hope atomized in silenced individuals.

@mrvwbug4423 I agree. I think NK sits back and sells whatever it can to China. Same MO they use with Russia. No serious quantity of NK troops to Ukraine, just arms for money.

Every US citizen gets a managed investment account starting at birth or a certificate of pregnancy. The account is funded with quarterly installments of loans by the FED open market window at the lowest possible interest rate, and as much as possible below the interest rates on the national debt. Part of the account is in US T-bills. This distributes interest earnings on the national debt to the citizenry. Earnings on the accounts service the loans from the FED. Strict rules prevent the use of the account in a way that would result in its demise or lack of value for the last years of the citizen's life. The account is not so large in value in the early years that it disincentivizes work in the productive years. Accounts could be used to mitigate student loan risk, to facilitate the purchase of a home, severe medical costs, and for disaster relief or disability. This can create a hybrid system that stabilizes the Social Security and Medicare Trust Funds. Existing investors would find the new influx of capital into the markets to be advantageous to their interests, at least in the short run.

@ensteffo Colonialism has been replaced by global trade, something China, Russia, the US and others engage in. The aggression is the drive to become the sole source and control the spice (Dune), I mean price.

user-tn8uu2cu8g Whoever has My commandments and keeps them is the one who loves Me. The one who loves Me will be loved by My Father, and I will love him and reveal Myself to him.” 22Judas (not Iscariot) asked Him, “Lord, why are You going to reveal Yourself to us and not to the world?” 23Jesus replied, “If anyone loves Me, he will keep My word. My Father will love him, and We will come to him and make Our home with him.

Don't worry. The Russians and Chinese know a lot more about these subjects than the American public. However, as we see in Ukraine, they haven't necessarily figured out how to make and use these things as well as the highly paid US MIC. I didn't hear anything that was a serious revelation.
