I hope you'll excuse some pushback from another layperson--isn't the situation with Aircraft Carriers categorically different? In the examples you provided above (Cavalry, Tanks, and Battleships), there has never been a push-button solution to eliminating every single unit in the service of the enemy. Given the technology mentioned by GP, the small number of Carriers in service and the utter impossibility of hiding them, it would appear that such a solution does exist for Carriers.

So while it seems to be true that Aircraft Carriers are not obsolete in peacetime or in a conflict with minor powers, aren't they obsolete in the context for which they were created--namely, war with another great power?

[greedo]

Weapons on their own are dumb, stupid devices. Weapons in a system can be dangerous when deployed appropriately. For ASBM or hypersonic missiles, there are several steps in a successful engagement:

1. Detect the carrier. Sounds easy but they can move at 30+ knots, and can be quite difficult to detect when they want to hide.

2. Provide targeting data. This is needs to be much more accurate than just detecting that a carrier is operating "near" this point. Most weapons will require relatively precise data for this.

3. Transmit this data rapidly to the launch systems. Every minute counts as old targeting data is relatively useless.

4. Launch the weapon. This means keeping aircraft or missile batteries safe from attack, and getting the weapons in range of the carrier.

5. Have the weapon reach the target area. This means a reliable weapon with a low failure rate.

6. Have the weapon avoid any ECM or other countermeasures that might affect its targeting.

7. Have the weapon avoid any defenses, either the layered defenses (SAMS, point defence guns), fighters, etc.

8. Have the weapon detonate properly, in the best spot.

Lots of things to go wrong in this "kill-chain." Lots of places to interrupt, disrupt or out-right kill the weapon.

And sure we hear a lot about Russian super weapons like Zircon and the silly torpedoes. But as the Ukraine war is showing, a lot of Russian stuff sounds great until you see it in action. Or it's a Potemkin weapon, or too expensive.

Look at all the burning Russian tanks. These aren't monkey models sent to client states like Iraq. These are top of the line, with ERA etc. Yet most don't have Arena/Trophy, and are getting killed by a weapon designed 30 years ago.

Now perhaps the DF-21 deployed by the PLAN is more reliable than the Russian crap. But unless things get hot in the South China Sea we'll never know.

Russia has been rather subdued in the Ukraine invasion, but they have won 95%+ of every military engagement in Ukraine: https://en.m.wikipedia.org/wiki/List_of_military_engagements...

They have taken nearly the entire Black Sea coastline and most major cities east of the Dnieper River. That entire eastern part of Ukraine will collapse imminently under Russian advances.

And meanwhile none of the aforementioned weapons systems have been engaged.

Detecting a carrier is trivial. They are large above surface vessels that leave a huge wake. 30 knots is nothing. And once locked its trivial for satellites or spy planes to track. We even publish the location of our carriers: https://www.marinevesseltraffic.com/vessels/USS-Enterprise-(...

Russia is a spacefaring, highly advanced military. They have all of the targeting capabilities you describe.

100 megaton nuclear torpedoes aren't silly. They're extremely dangerous. They can trigger tsunamis, and destroy anything within tens of miles and cause third degree burns out to hundreds of miles.

I'm not sure you understand the scale of what you're dismissing.

> Russia has been rather subdued in the Ukraine invasion, but they have won 95%+ of every military engagement in Ukraine: https://en.m.wikipedia.org/wiki/List_of_military_engagements...

You mean 95% of the ones on that list, which was made by an external observer. It's also a military engagement each time one of their vehicles gets exploded by a TB2 drone strike.

Their equipment losses: https://www.oryxspioenkop.com/2022/02/attack-on-europe-docum...

Most of these aren't in battle, it's because their equipment breaks on its own because they didn't maintain the tires for years, or runs out of fuel because everyone in the supply chain sold it for food money.

The Wikipedia map is good, but it's also out of date on that page, and the positions haven't moved much since then.

https://www.understandingwar.org/backgrounder/russian-offens...

[chrisco255]

"Their equipment losses:"

I'm skeptical of any list of equipment losses being comprehensive on both sides. We are very much in a fog of war situation.

The map you linked looks fairly dire to me. The Russians control the Sea of Azov and the Black Sea at this point, and all of Ukraine's eastern border. With Belarus to the north, it leaves Ukraine landlocked with only its western border for imports and exports (mainly via Poland). There's a cauldron

Russia has already captured many of the major cities east of the Dnieper, and it will be harder and harder for Ukraine to supply the eastern front, particularly across that river.

[greedo]

The aforementioned weapons systems only exist in labs if that. Hypersonics are expensive and Russia is poor. Look at their GDP.

And you do realize that satellites don't "lock" onto anything. They orbit around the earth. Geosynchronous orbits aren't used by RORSATs. Spyplanes? What spy planes? Russian maritime surveillance aircraft have limited range, (as do the PLANs) and can't see an infinite distance. Google the earth's curvature and you'll be able to find out how radar is limited.

Russia's military is a Potemkin village. Has been for decades if not longer. The only thing they have that's a threat is their nuclear weapons, and I'm even starting to wonder how reliable those are.

You keep talking about how dangerous Poseidon is. But Status-6 hasn't even been deployed, and probably never will. Why not talk about how dangerous Tsar Bomba is? And it's estimated speed is closer to 60mph.

I grew up when the Soviets were all 10 feet tall, with super T-80 tanks, with SS-20 missiles, nuclear powered cruisers and all sorts of scary stuff. Most of it turned out to be junk or too expensive for the USSR to afford. Same with Russia.

"The missile can be armed with a nuclear or conventional warhead and has been tested several times over the last few years in the Barents Sea and White Sea regions, both from surface warships and the latest class of multi-purpose submarine."

Sometimes it matters what a country spends its budget on rather than how much.

This is all noted by our own DOD: https://media.defense.gov/2018/Feb/02/2001872886/-1/-1/1/201...

"U.S. efforts to reduce the roles and numbers of nuclear weapons, and convince other states to do the same, have included reducing the U.S. nuclear stockpile by over 85 percent since its Cold War high. Potential adversaries, however, have expanded and modernized their nuclear forces."

"Russia possesses significant advantages in its nuclear weapons production capacity and in non-strategic nuclear forces over the U.S. and allies. It is also building a large, diverse, and modern set of non-strategic systems that are dual-capable (may be armed with nuclear or conventional weapons). These theater- and tactical-range systems are not accountable under the New START Treaty and Russia’s non-strategic nuclear weapons modernization is increasing the total number of such weapons in its arsenal, while significantly improving its delivery capabilities. This includes the production, possession, and flight testing of a ground-launched cruise missile in violation of the INF Treaty. Moscow believes these systems may provide useful options for escalation advantage. Finally, despite Moscow’s frequent criticism of U.S. missile defense, Russia is also modernizing its long-standing nuclear-armed ballistic missile defense system and designing a new ballistic missile defense interceptor."

[greedo]

Oh and I forgot to address your ridiculous comment about winning every engagement in the Ukraine. Tell that to the 7K dead Russians. How about the 400+ destroyed MBTs, and 4K IFVs? If you think that Russia is winning this conflict currently, you've been listening to Tucker Carlson too much. Russia lost this war on D Day, when they failed to establish an air bridge at Hostomel when the VDV got smoked.

[chrisco255]

How many Russians are dead? Who counted the bodies and how did they do so during an active engagement? How many Ukrainians have died by comparison? Do you have complete information or do you have incomplete information during a literal fog of war situation?

https://en.wikipedia.org/wiki/Casualties_of_the_Russo-Ukrain...

Russia says they've lost 400 men, USINT says 7K. Who's telling the truth? They're both known to lie.

We can be relatively sure, based on the numerous maps of Russian advances that eastern Ukraine will fall in the next couple of weeks. You let me know if that's a win or a loss. I'm not sure. It's certainly a thing.

https://www.bbc.com/news/world-europe-60506682

[greedo]

Hmm. Looks like Eastern Ukraine is still in Kiev's control. Russia's losses have been phenomenal.

[greedo]

That map (nor most of the unbiased non-Russian ones) doesn't show an imminent collapse in the next two weeks. According to the UK MoD the invasion has reached a standstill. Hope you'll be back in two weeks with more accurate information...

[thereddaikon]

As long as its useful to have a self propelled airbase that can launch strike aircraft from anywhere it goes air craft carriers will be relevant.

Emerging threats may change tactics, operations and spur development of countermeasures but they wont make an entire weapons system obsolete unless the change the nature of war.

>Given the technology mentioned by GP, the small number of Carriers in service and the utter impossibility of hiding them, it would appear that such a solution does exist for Carriers.

Carriers are not impossible to hide. A CSG that doesn't want to be found can do so. The ocean is a very big place. There are also grades to knowing "where" something is. Just knowing there is a carrier in the South China sea is valid for strategic planning but not much else. Knowing its somewhere to the south west of Taiwan can help plan operations but wont put warheads on foreheads.

A complete kill chain involves getting very precise and timely targeting information. This is something that needs to be done with some kind of sensor, RADAR, Thermal, Sonar etc. It must be timely because carriers are moving targets. A mere set of GPS coordinates is not good enough. By the time your missile gets there they will be wrong. So that means you need something nearby with a datalink and proper sensors to give targeting data. This could be a sub listening with sonar, a strike aircraft painting the carrier with radar or using an IRST to pick up its heat signature. It could be a warship of your own.

Point is, these kill chains are long and complicated and if you break it at any point your attack will fail or wont happen at all. Hypersonic missiles have very long kill chains, some of the longest. And they haven't been proven out in combat. "Finding" a CSG is much easier said than done.

> Given the technology mentioned by GP, the small number of Carriers in service and the utter impossibility of hiding them, it would appear that such a solution does exist for Carriers.

Strategic nuclear weapons, which one of the items you are referencing is, have been the “make it all go away” button for lots of things since they were created, but…MAD.

As for conventional anti-shipping missiles, people have been arguing that about carriers since weapons like the Exocet were available, but today, as then, remain at best highly speculative.

> So while it seems to be true that Aircraft Carriers are not obsolete in peacetime or in a conflict with minor powers, aren't they obsolete in the context for which they were created--namely, war with another great power?

Maybe, but so what? MAD has made war between great powers even more the exception among wars involving great powers than it was in the past, and it's almost always been the exception.

[pavelrub]

No. Because you have to consider:

1. Current or future means of intercepting hypersonic missiles.

2. The ability to disable or reduce the enemy’s ability of launching hypersonic missiles, or of pinpointing and accurately tracking the exact location of aircraft carriers.

[chrisco255]

We don't have the capability currently to intercept Russia's hypersonic missiles.

We also have no defenses against 100 megaton underwater torpedo nukes that can be detonated miles from a carrier group and still wipe it out.

In an all out war with Russia, our carriers would be big, slow, sitting ducks against Mach 20 missiles with variable speed and high maneuverability as well.

https://www.military.com/equipment/weapons/why-russias-hyper...

"The missile flies with an advanced fuel that the Russians say gives it a range of up to 1,000 kilometers. And it's so fast that the air pressure in front of the weapon forms a plasma cloud as it moves, absorbing radio waves and making it practically invisible to active radar systems.

U.S. Aegis missile interceptor systems require 8-10 seconds of reaction time to intercept incoming attacks. In those 8-10 seconds, the Russian Zircon missiles will already have traveled 20 kilometers, and the interceptor missiles do not fly fast enough to catch up."

[thereddaikon]

>We don't have the capability currently to intercept Russia's hypersonic missiles.

Say hello to SM-3. It has successfully intercepted hypersonic RVs in testing. Is it perfect? No. But if it done anything, the last month has made me feel more confident in what the US claims their weapons can do and dismissive for the Russians.

>We also have no defenses against 100 megaton underwater torpedo nukes that can be detonated miles from a carrier group and still wipe it out.

No such weapon exists. And if it did it would be wildly impractical. The largest nuke ever made was the Tsar Bomba and it was only 50 megatons and too large to be practical.

And we do have a counter to nuclear torpedoes. Its called the West's nuclear deterrence. Using a nuke on a carrier means nuclear war and nobody wants that.
