You could paint the target using a laser, with the rocket-propelled drones homing on to it. Or extremely precise GPS coordinates!
Wait... It reminds me of something: https://en.wikipedia.org/wiki/Precision-guided_munition

I agree. But the only platform able to consistently engage a carrier group with this kind of firepower is another carrier group. Land-based artillery can be kept out of range or engaged using the force projection of the carrier.
>So would a submarine intelligently positioned.
Submarine capabilities are some of the most well-kept military secrets of the world. There is no way to assert that. In modern doctrines, they are mostly used for intel and as a platform for launching ICBMs, so I would really not bet on that.
>The ability of a group to counter a strike from high altitude is also very questionable and let’s not mention the very real anti-ship ballistic missiles.
That is true. Spamming ICBMs could work, and they don't need to be nuclear to defeat a modern carrier group :)
>Carriers really are a technology of the past for symmetric conflicts.
This is absolutely and provably false. No systems allows for the force projection that a carrier group afford. France was able to deploy & support an incredible amount of power from the Charles de Gaulle against the Islamic State. No other system could have achieved that. https://en.wikipedia.org/wiki/French_aircraft_carrier_Charle...

- Effective countermeasures already exists against this kind of threats, like CIWS.
- Carriers don't exists in a vacuum, there are a lot of other systems in a modern carrier group.
- Just like launching a missile barrage, deploying the tens/hundreds of thousands of drones is going to be quite the logistical achievement, especially bringing it in range of a modern carrier group, designed to project force against threats hundreds of kilometers away.
- Drones have significant range/projection issues. The Bayraktar, at $2M a piece, has ~300km of range and can only bear a very small payload designed to engage armored ground targets, nothing that would threaten carriers or destroyers, even deployed en masse.
- The bigger the range, the bigger the payload, the bigger the size/costs. The effectiveness of your drone swarm is always limited by this equation. Millions of small aliexpress drones bearing the equivalent of a hand grenade are not going to do anything against a carrier provided it can be deployed at all. You would need to be <10km away due to their range limitation and at this stage, there are already fighter jets and destroyers sitting on top of you.
- No single munition under the kiloton order of magnitude will sink an aircraft carrier. For a drone or anything under the scale of cruise missiles/MOAB, this means nuclear. Hand-grenade sized nuclear explosives in drone swarms? I wish! But to quote the fantastic game Highfleet, once you get the genie out, you cannot put it back in the bottle. If you plan to bring nuclear weapons to a war, everybody already has ICBMs.
tl;dr: Drones swarms don't disrupt the current status quo: Nothing except nuclear attacks or another modern carrier group will defeat a modern carrier group in a single engagement. The usefullness of drone swarms is not against modern carrier groups but small-scale asymmetrical engagements, such as the guerilla operations currently carried in Ukraine or in Syria, in which small drones are incredibly effective weapons. This is still a big deal, as it is the most likely form of conflict we're going to see in the rest of this century, not full-on peer-to-peer conflicts between superpowers.

On the video, the ukrainian tank is of course performing an effective ambush. I don't pretend I have the answers, but I wonder how would perform a bunch of infantry with NLAWs striking the column from multiple places at once, for cheaper than the tank, able to engage multiple targets at once, much less spottable, and so on.

Handheld old anti-tank weapons like RPGs with HEAT warheads were extremely unreliable, defeated by reactive explosive armors, successful only at very close range and so on. Modern ATGMs able to be fired from kilometers away and with >90% kill rates completely changes the dynamic. Those systems are only going to get smarter and cheaper when there is a physical limit on the armor+weight+cost+logistical support equation for tanks.

If this exists, why did the USMC binned their tanks 2 years ago stating they weren't cost-effective anymore? I'll believe this exists when I'll see it, but so far we have seen $4M tanks defeated by $100K javelins with a 93% kill rate, and so far cope cages have done nothing against them.

Until very recently, 2 guys hiding in a bush couldn't kill a tank, you needed a predator drone, an helicopter or some other advanced system requiring heavy logistics. Now behind every bush and every road corner is a potential enemy able to defeat you. With >90% kill ratio for javelins, the tanks needs to be lucky for weeks on end to survive, and the ATGM needs to be lucky only once.

"This advisory was developed after a review of human studies on the relationship of dietary cholesterol with blood lipids, lipoproteins, and cardiovascular disease risk to address questions about the relevance of dietary cholesterol guidance for heart health. Evidence from observational studies conducted in several countries generally does not indicate a significant association with cardiovascular disease risk."
Dietary cholesterol is not a threat, surplus calories and processed sugar is.

Absolutely! I would like to see a political entity led by Kantian ethical formalists. My opinion is that such a faction couldn't come into power. Let's hope I'm wrong.
>Relevant case in point: I live in New York, where until recently we had a governor that was all about ruthless assertion of power and ruled by personality. Then, when he ran into problems everyone turned their back on him because everyone hates him.
Sure, the history is littered with the corpses of the Hitlers and Mussolinis (and the mountains of corpses they have caused), the small petty tyrants who thought brutality and charisma it was ALL you needed to rule. They meet their ends alone at a moment or another, but this doesn't make a case for the success of ethical leaders either.
