I can think of only a handful of targets that the US might want to shoot at. (I realize there might be a ton, and this is my lack of imagination). The handful I can think of, almost all of them seem like they're in the supply chain to actually build the torpedos. I'm pretty skeptical of the depth of the US stockpile.
To put it another way, if there was a war so bad, the US reinstituted the draft, would these tools still be relevant? The US industrial base is mighty, and could certainly retool to meet whatever need arises, but that'll take years.
Really seems neat, but after you've taken your 20 or 50 or whatever shots, how do you resupply? Seems like you'd need special coatings or shelf stable chemicals or a hundred other things to make the super fancy weapon.
it sure _seems_ like (although I have no fucking clue, so I'm asking) the super fancy weapons are available for a few weeks if things get real bad.
_edit_
realized I didn't actually ask a question. Can the US actually build these things from, like, minerals? It's a big country, we have them. The industrial base doesn't seem tuned for actually doing that though.
_further edit_ I'm a very silly person. it seems like the only must have is a plausible second strike capability. It's great to be able to protect the free flow of oil, or defend the Kurds from chemical weapons. Hell, one of the most American things I can think of is protecting yankee clippers for safe trade. It's part of the Marine's Hymn. but clearing pirates from the shores of Tripoli isn't absolutely vital. I'd sort of thought that subs jobs in the modern world was making sure that if the US can't play, no one else can either, with moderately sized nuclear weapons. Again, I'm a very silly person.
The question with the further edit is, do subs have an essential job beyond second strike cabability?
> if there was a war so bad, the US reinstituted the draft
US has something better than the draft: poverty. As long as there's a large enough pool of young people without options, there's no problem. A draft generally can only be minimally discriminatory for PR reasons, so poverty as enlistment incentive works much better.
Though, talking about US military running out of manpower is a far, far fetch, isn't? It surpasses or is extremely competitive with any other military by any measure [0][1].
According to Blind Man's Bluff, which covers submarine warfare during the cold war from the US perspective, right up to the nineties, atomic subs had 3 main roles: espionage and intelligence gathering, preserving second strike ability, shadowing enemy subs to have a chance of thwarting their strikes in case of crisis. What submarine warfare was during the cold war, right up to the end, was largely defined by the technical superiority of US subs, especially their ability to remain undetected. By the collapse of USSR, Soviet subs were about to catch up in terms of essential technology. I would be intrigued to learn what sub warfare is like now.
Currently most military recruits come from the middle classes. Youths in poverty typically fail to meet enlistment standards due to health problems, low standardized test scores, criminal record, drug use, etc. Of course there are many exceptions but that's the general rule.
> An important predictor to military service in the general population is family income. Those with lower family income are more likely to join the military than those with higher family income. Thus the military may indeed be a career option for those for whom there are few better opportunities.
Now that we have a volunteer army, there are differences between how the wars of today are fought compared to the Viet Nam war. The Viet Nam war had literally an order of magnitude more deaths than our current wars. Having a volunteer force means the soldiers have to treated better and paid more than a draftee. These wars have been a waste of lives and money but things would have been much worse if there were millions of draftees serving in the middle east and Afghanistan. Having a volunteer force in the 1960s would have meant that if the Viet Nam war would have been fought, there would have been with a lot more concern for the loss of life of the solders - it likely wouldn't have been fought anything like it was fought.
The USA should use this opportunity to step back and re-think whether registering for the draft is needed in this age. The whole draft registration program is simply a waste of millions of dollars a year.
I don't (off the top of my head) remember my sources for claims about poverty being a mechanism for manning the US military, so I won't push the point. I'll leave it at saying that I wish you were right.
You're definitely right that it's a recruiting pressure - that and the free college and the path to naturalisation. But that only holds as long as the casualties are relatively low. And the ~4k dead and ~30k wounded of Iraq was relatively low compared to the ~58k dead of Vietnam. It's not clear what kind of non-nuclear war would bring that level of dead again, but I reckon restarting the Korean war would do it.
The US industrial base was mighty, but these days it's a very pale shadow of what it was. Rampant cost cutting, outsourcing, and lack of protecting domestic production has absolutely devastated US manufacturing. There's still lots of design work that goes on, but almost all the actual manufacturing takes place elsewhere. What little is actually "made" in the US is almost entirely assembled from raw components that are themselves manufactured outside the US.
> Rampant cost cutting, outsourcing, and lack of protecting domestic production has absolutely devastated US manufacturing.
This is utterly false thing that you learn if only read news articles. The value and quantity of manufacturing is now the highest it has ever been in the US.
What has declined is the number of workers and the share of GDP. This applies to almost all OECD countries. As economies change from industrial to post-industrial, the share of manufacturing declines naturally because manufacturing productivity increases.
Agriculture is something like 3% of the GDP, yet developed countries produce more agricultural products than they did when 90% of the economy was agriculture. The same thing is happening to manufacturing.
> This is utterly false thing that you learn if only read news articles. The value and quantity of manufacturing is now the highest it has ever been in the US.
I've seen it first hand. I've talked with people that have been impacted by it. I've also seen the corporate slight of hand that tries to disguise it. Components manufactured in China, shipped to Mexico for assembly, then shipped to the US to have some decorative panels and stickers slapped on so they can put a "made in USA" sticker on the side.
Go grab virtually anything from around your house (excluding food) and it's more likely than not that that thing was manufactured in whole or in part outside the US. That didn't used to be the case. Coming out of WW2 it was rare for people to own non-domestically produced goods.
This isn't a case of US manufacturing just being so ridiculously efficient that you just don't need many companies making things. That might hold water if most goods were still manufactured in the US, but they aren't. Cars are about the only manufactured consumer good still made in the US, and even they are quite often assembled in Mexico. Pretty much any electronic device is made in China.
Here's a case study, Ikea which is a very popular furniture manufacturer (among other things) mostly assembles their products in Mexico and China. They do have some US manufacturing, but that's largely because they acquired rights to some large swaths of woodland and it makes sense to process and assemble that on site.
To be clear, you mentioned agriculture, and yes, the US does have a thriving agriculture sector, but agriculture isn't manufacturing.
The US screwed up badly when it let basic manufacturing get outsourced. When the factories making screws and transistors are all based in other countries, eventually all the other factories are going to follow them.
You can't quantify manufacturing by looking around. What you see is cheap consumer products with low value added.
If you follow value chains for products manufactured in China, you quickly notice China imports high value added manufacturing products from other countries (including the US) then assembles them with cheap workforce and adds cheap components.
>Manufacturing can be for goods that you don't find in your house?
>If you look at the German mittelstand there's a lot of businesses that make stuff for some unknown-to-the-public industrial niche.
>I'm guessing the US also has a bunch of those.
And that is exactly why he said "from your house". Home goods lend themselves very, very well to outsourcing because low initial cost is such a key design criteria and they tend to have a density and packaging requirements that make them convenient to ship. If you browse through the McMaster or Grainger catalogs you'll find that a huge number of things (maybe not a majority but likely the largest minority) are made in the US and the rest are made all over the world.
You’re talking about cheap consumer products that will always be made cheaply.
No one is going to make a consumer product like they used to. Take power tools and kitchen appliances for example. They don’t have to be make entirely of metal when plastic will do just fine for home use.
Like Germany we want to keep high quality manufacturing at home.
According to wikipedia the US stockpile of Mark 48s is over 1000, and the current manufacturer is building about 50 a year, which certainly seems like enough for a little bit. Most military manufacturing happens in country or in an allied country, and there are people in the military devoted to making sure the supply chain for this stuff is healthy, and making sure there is room for surge if needed. As for overseas needs, it's hard to imagine a scenario where the US Navy is unable to defend American convoys in the Atlantic (linking them to manufacturing and raw materials in South America, Europe and Africa) at least not in the first year of the conflict.
Of course in a total war scenario things start to change. When it's truly nation against nation in a global conflict every part of society needs to be re-tooled into a giant war machine. In WW2 the US told General Motors how many cars they were allowed to make a week, because they needed steel for tanks. I imagine any facility capable of making electronics in the US and Europe today would be re-tooled to make the chips for Mark 48s, AIM-120s, SM-2s, etc.
EDIT: Oh, and in a total war scenario, submarines are essential weapons. Remember, a total war isn't just army against army, it's also economy against economy. If you can deny your opponent access to the resources it needs you can win the conflict, and that means you need submarines to sink enemy supply convoys. This would certainly come up in a hypothetical Sino-American conflict. The overwhelming majority of Chinese imports and exports come through ports. The port of Shanghai alone gets more tonnage of supplies in and out in a month than all land routes in and out of China COMBINED get in a year.
> To put it another way, if there was a war so bad, the US reinstituted the draft, would these tools still be relevant?
The drafted people would all go to factories and boatyards to build thousands of new submarines. Each submarine would likely have no people on board, and be fully remote control.
The age old problem of "you can't hide while sending and receiving data, so you can't make a drone sub" has been solved by using below-noise-floor gold codes, so without the coding key, nobody can even tell a transmission is going on.
I'm a cryptographer, so I'm inherently curious about secret communication. It just so happens that I'm also very curious about radios, satellite communications, etc.
Do you have a link that provides more information on these "below-noise-floor gold codes"? I tried googling, but I haven't found much technical information that I trust is entirely truthful or relevant.
The principle is that if your ally has a receive antenna with a gain of X, and you use a modulation scheme with a coding gain of Y, and you transmit strong enough that your signal can be received by your ally with a snr margin of Z, then as long as your enemy doesn't have a receive antenna with gain > X+Y-Z, they can't detect your signal from the noise.
Since Y can be increased arbitaraly (at the cost of channel data capacity), it's always possible to transmit some information to your ally without your enemy seeing a transmission, it might just be a few bits per second, but theres a lot you can do with a few bits per second in warfare.
One needs to make sure that the above holds true for all possible frequency windows and time windows, so no carrier waves or high power sync pulses!
I believe the implementation is much harder than the theory - just one crystal oscillator or PLL anywhere in your radio hardware will leak some of that frequency into the output, and since the bandwidth of a crystal oscillator is super low (obviously an ideal oscillator has zero bandwidth), even a tiny leak is detectable by an enemy.
No doubt that's what the end of the war would look like. But war is, generally speaking, a kind of work on the field. That kind of work isn't currently done by robots.
I have read the comms channels underwater are low to very low bit rate. If true, a remote controlled sub seems unrealistic.
Also a remote control sub would be continually sending data back which surely is tantamount to continually yelling "I'm here! I'm here!", so I don't really buy the RC sub theory yet. (edit: I don't buy your suggestion that it's possible to hide that. You just need to emit too much power and you can't hide that).
Correct, you can’t remote control a submerged submarine, you get maybe a few characters per minute rate of transmission. There are a few ELF stations throughout the world, the US, Russia and India all having some.
Some more info: https://en.wikipedia.org/wiki/Extremely_low_frequency which has my favorite quote. “ ... few nations have built naval ELF transmitters to communicate with their submarines while submerged. China has recently constructed the world's largest ELF facility roughly the size of New York City in order to communicate with its submarine forces without having them to surface. ...”
The antenna needed for these transmissions requires a lot of land.
That's not true. I was working on a system to do (not on subs, but the techniques are applicable) that a few years ago. With a big enough array, anything is possible, see the entire field of radio-astronomy. This includes sparse arrays, as long as you have good enough time sync to do coherent integration.
I can think of only a handful of targets that the US might want to shoot at. (I realize there might be a ton, and this is my lack of imagination). The handful I can think of, almost all of them seem like they're in the supply chain to actually build the torpedos. I'm pretty skeptical of the depth of the US stockpile.
