Re:Nukemap by tablespoon on Friday March 11, 2022 @03:09PM (#30645374)
I was looking at this the other day, and was wondering how nuclear weapons would actually be targeted against the US. Would they be aimed at city centers or nearby infrastructure? Would each city be targeted with one warhead, or blanketed with several over a large area?

Because if there's a full-scale nuclear war, if the Russians only target the center of my city, I probably have a chance of surviving. However if they target the civilian airport (where there's also a small ANG presence) or use multiple warheads for the metro area, I'll probably be vaporized.

Obviously I know no one posting here can answer definitively, since I'm asking about some of the toppest of top secret stuff.

Re:Nukemap by nostrademons on Friday March 11, 2022 @03:46PM (#30645791)
The vast majority of nukes are "counterforce" - they're targeted against military targets, primarily the enemy's own nuclear arsenal. Strategic reasoning for this is pretty simple: only by destroying the enemy's weapons can you prevent the destruction of your own citizens, and destroying the enemy's citizens is pretty cold comfort if all of yours are dead. I've heard that each Minuteman 3 silo in the U.S. has multiple nukes targeted on it, because they want to be really sure that they destroy that missile if it hasn't left yet. Many of these warheads are SLBMs, where flight times are only a couple minutes, so that they can hit as soon as it looks like a launch is imminent.

After ICBM silos, primary targets are (roughly in order):

1) Runways longer than 7000 feet, long enough for a B-52 to take off and land.

2) Naval bases, primarily those involved in the basing and maintenance of ballistic missile subs.

3) Command and control facilities of the U.S. military and government. This includes much of Washington D.C, the Pentagon, major government institutions like the CIA and NSA, and secondary military bases where leadership might relocate to.

4) Port facilities, which may become naval bases in a war.

5) Refineries and oil fields.

6) Concentration of heavy industry where military equipment might be made. Think of metro Detroit auto factories, or Caterpillar's factory, or Hendy Ironworks in Sunnyvale.

7) Office parks where significant brain trusts are located. You can bet that Livermore, Apple's headquarters, and the Googleplex are on a target list. (The Googleplex is actually in the blast radius for Moffett Field, so it may not need to be a separate target.) Also major universities.

8) Major city centers.

If you live in a suburban bedroom community, there is a very high chance of you surviving an initial attack unscathed. Nuke blast radiuses are often surprisingly small, relative to metro areas, and there is no reason for Russia to target a lightly-populated bedroom community 10 miles outside of the city.

Re:Nukemap by agency on Friday March 11, 2022 @04:06PM (#30646023)
"Fun" fact: Seattle is 20 miles (as the crow flies) from Naval Base Kitsap which is the home port for all of the pacific fleet of Trident ballistic missile submarines.
Re:Nukemap by hollerith on Saturday March 12, 2022 @03:04PM (#30654420)
From which I conclude that unless they make the mistake at looking at one of the explosions, in which case they'll be blinded (probably temporarily, but I'm not sure) or they're injured by flying glass, Seattle residents will not be immediately killed in an attack on Kitsap, but if the wind is blowing in the wrong direction or it rains at the wrong time they could easily be killed by the fallout.

Do you have a source for this? It seems (coldly and terrifyingly) sound from logical perspective, at least to the extent that "logical" is a word that can be applied to something that threatens the entire human race.

But I'm curious how much if any official doctrine has become public.

    If you live in a suburban bedroom community, there 
    is a very high chance of you surviving an initial 
    attack unscathed.
One might imagine a regime that was sufficiently evil and/or endangered enough to launch wide-scale nuclear attacks might also spare a few warheads for such bedroom communities as well, especially if resistance continued after an initial exchange. Would be a terrifyingly effective way to cow a populace - to make them feel nowhere was safe.
Re:Nukemap by hollerith on Saturday March 12, 2022 @03:10PM (#30654461)
>Do you have a source for this?

I don't have sources, but the list is very similar to the list I would write. I have no work experience in the field, but since the end of the cold war, my probability of nuclear war has always been much higher than most English-language commentators, so I've been keeping an ear out for information.

I would add that runways over 7000 feet would be such a high priority that even straight stretches of highway longer than that (which can be used as improvised runways) will probably be targeted (and some sections of the US interstate highway system built in the 1950s were made straight precisely so that they could be used as runways during a war).

Also, it is at least possible that they would attack the US, but not with everything they got (at least at first) and if they do that, then oil refineries would be much higher on my list than on the list in the grandparent comment because if they do decide to attack, it is probably because they (the leaders of Russia's security apparatus) are about to lose power in which case it is likely that they blame the sanctions the West has just imposed on them as the primary cause of their immanent loss of power -- and their attacking our oil refineries will have an effect on the US much like very severe sanctions would.

"Unscathed" is a questionable term here. Sure you likely don't get vaporized in the initial blast, but given grounds strikes, which to my understanding are more likely in a modern nuclear exchange you likely get enough radiation from the fallout you wish you had been vaporized. Depending on prevailing winds this can be true for a shocking distance from the impact site.

Re:Nukemap by sdoering on Friday March 11, 2022 @03:47PM (#30645803)
With nuclear weapons you know that getting all enemy weapons is a slim chance. So you aim for maximum destruction of the enemy.

If I had to decide on targets I would go for max destruction in terms of lives. In the initial impact and in the long term. So the biggest cities, nuclear power plants, water supply, food production.

As said when usi g this option I don't expect my people to survive as well.

Re:Nukemap by hutrdvnj on Saturday March 12, 2022 @02:56AM (#30649789)

Re:Nukemap by wonderwonder on Friday March 11, 2022 @05:20PM (#30646749)
A Nuclear exchange is not really to make the other side concede. Both sides know if they fire nukes the other side will respond in minutes with their own massive salvo. The initial strike is essentially to render as much of the enemies military ineffective especially their nukes. Surviving for a second strike is not a given. In the event of a nuclear strike I think both sides understand that there wont be very many people or leadership to concede. Hence the term Mutually Assured Destruction.
Re:Nukemap by kmonsen on Friday March 11, 2022 @03:27PM (#30645563)
It really doesn't matter, and honestly you probably want to die in the first blast.

If there is full scale nuclear war there seems to be consensus that there will most likely be full breakdown of normal society and probably a nuclear winter. Either one of those would mean your job is probably long gone if you are an HN reader, food is going to be scarce and there is no police to protect you anymore. Basically fallout on steroids, but with less mutants and also less food.

Personally I don't think the human race will go extinct, but the ones that do survive are not going to live in comfy modern societies anymore. And if you are living somewhat close to a nuclear strike you are going to miss that hospital when radiation sickness sets in.

Each to their own but I have never understood this way of thinking. I have kids, I would want them to survive and to have a chance at life even if its not the shiny modern one. I would also want them to have kids and so on. Life would obviously be hard but it would still be life. Death comes soon enough for everyone anyway. Obviously the best outcome is no nukes at all.
Re:Nukemap by minot on Friday March 11, 2022 @03:42PM (#30645743)
I think the difference is I don’t have kids. I would like to think I want kids but there is no way I can afford having kids especially given I’m not sure if I can even afford to retire.

I don’t understand the way of thinking of people millennials and later who aren’t at least millionaires who choose to (not counting accidental pregnancies) have children.

Re:Nukemap by jupp0r on Friday March 11, 2022 @03:55PM (#30645878)
You could choose to live somewhere where you don't have to be a millionaire to have children. Lots of people move out of San Francisco around the time they are starting a family, for example.

Incidentally, these areas might also be less likely to be hit by nuclear bombs.

Re:Nukemap by nostrademons on Friday March 11, 2022 @04:06PM (#30646025)
I'm a millennial with kids. I've been predicting that the world ends in nuclear holocaust for the last 15-20 years or so, since I was a teenager. My wife and I had the "If the future is going to be as bad as you predict, why bring someone new into this world?" conversation before we chose to have kids.

The simple reason is that if we don't, we lose by default. Survival is the Great Game, the one that has been going on throughout history and will continue to go on for as long as life continues to exist. In the U.S. we've been lucky enough to not need to play the game for the last 3 generations or so, with survival basically assured, and so a lot of people have forgotten how to play. In its absence, we've made up a lot of other games, like "Will I get more karma on Hacker News?" or "Will I get promoted at work?" or "Will I get rich by picking the right cryptocurrency?" But it's worth remembering that these are games, on some level their results don't matter (certainly not if there's a nuclear holocaust), and we may be once again called on to play the Great Game again.

So I just try to be grateful that I don't have to play the survival game right now, while keeping perspective and remembering that that can change in an eyeblink, and trying to keep my wits and skills sharp enough that I could pick it up again if needed.

Re:Nukemap by beeboop on Friday March 11, 2022 @05:30PM (#30646848)
I'm a millennial and have also chosen to not have kids (vasectomy) for similar reasons - it's expensive, the world feels unstable, and mental illness is pretty bad for both me and wife. However I don't fault people who highly value having kids, and I think it's an extremely human trait to want them with a higher priority than anything else.

If I didn't have kids I think I would still want to live. In this scenario worst case I could voluntarily check out. You don't need to be rich to have kids friend. Don't get me wrong they are definitely a cost of living increase but all they really need is attention and to feel loved. Everything else takes care of itself. Of course they need food and shelter but housing is affordable away from major urban areas.

This is not to underplay the difficulty raising kids on a below average wage job.

Survival instincts are strong tho, suicide would be a lot more prevalent in war zones and heavily impoverished regions if the will to live didn't most often prevail on terrible living situations. As horrifying as the thought of a nuclear collapse of civilization would be, I'm sure there would be something worth living for on the other side - assuming you're somewhere that remains remotely livable and don't die a week later from body melting radiation poisoning or from famine within two months... which I guess is likely in most places, maybe it's my non-urban Canadian bias and irrational optimism (I'm doubtful this scenario equates a carpet-atomic-bombing of Earth's surface) speaking.
Re:Nukemap by awb on Friday March 11, 2022 @03:19PM (#30645484)
> Would each city be targeted with one warhead, or blanketed with several over a large area?

It depends on your objective if you want to incinerate a target, maximize damage or produce maximum fallout.

Basically if you want to incinerate a small, hardened underground target you need to send a few nukes to have a high confidence level of success. If you want to damage a city and are OK with detonating in any part of the city then one might suffice. If you want fallout then you want an air burst to the West and let the Easterly winds spread the fallout.

Each missile has it’s own distance and accuracy calculations.

The author has another site called Missle Map that explores these scenarios in much more detail:

https://nukemap.org/missilemap/faq/

> If you want fallout then you want an air burst to the West and let the Easterly winds spread the fallout.

This might be true, but I've heard speculation that a surface burst would produce more fallout. Their reasoning is that fallout from an air burst would have considerably less dirt or debris so it would (supposedly) remain airborne for a longer period of time. On the other hand, a surface burst would darn near vaporize anything in the blast radius, and all that newly created radioactive debris would fall much quicker.

My sources could be incorrect, so if you've got something that indicates otherwise I'd appreciate it if you could point me in the right direction. :-)

Re:Nukemap by yellowapple on Friday March 11, 2022 @04:12PM (#30646076)
Nukemap seems to agree that a surface detonation would irradiate a much wider area than an airburst.
Re:Nukemap by Spooky23 on Friday March 11, 2022 @03:33PM (#30645631)
I was into this topic awhile back, basically while nobody talks about the details, there are reports re the reactions of people when they learn of the details. And they are basically horrified, borderline traumatized, but cannot come up with another plan.

The number of missiles and warheads available are very high, and planners identify all sorts of targets and assign priority, etc. I would imagine that factored into that are significant operational failures, operators who refuse to act, etc.

I’d assume any military significant site, current or former industrial target, interesting infrastructure, etc would be targeted multiple times. In an area like NYC, Boston, DC, SFO, forget it. If you didn’t get vaporized, you’d probably wish you did.

Re:Nukemap by aerostable_slug on Friday March 11, 2022 @04:16PM (#30646115)
This is correct. Based on public statements, the record appears to be the Russian Don-2N battle management radar facility: in the 1998 revision of the SIOP, it had 69 consecutive warheads dedicated to its destruction [0].

Unless you are far far away (like NZ or Aus) you are better off dying instantly. Even far away, and even if there is no nuclear winter sort of result, the radiation and effects are likely get you as well. Volcanic dust can be pretty widespread (Krakatoa is likely bigger than all the nukes we have) but it's far more localized unlike a general nuclear exchange, plus the dust is likely to be both radioactive and contain all sorts of nasty volatilized chemicals.
Re:Nukemap by excalibur on Friday March 11, 2022 @03:16PM (#30645458)
Guessing there would be several aimed at each city of any size, and the targeted locations would be spread out a bit to maximize impact. If you're conducting an all-out nuclear assault you're probably not pulling any punches.
Re:Nukemap by javajosh on Friday March 11, 2022 @03:25PM (#30645545)
I was going to say there aren't enough warheads to target every city because:

>[The] United States and Russia have the vast majority of nuclear weaps, with 4,804 and 4,480 warheads stockpiled respectively. There are approximately 1,861 nukes spread over the rest of the world, between China, Israel, the U.K, Pakistan, and India. France has the largest number of nukes after the U.S. and Russia. [0]

However, there are only 326 cities with over 100k population in the US. [1]

It would not be hard to list out the most valuable US locations to destroy, government, business, and military, for either the goal of preventing C&C and/or for ending the civilization.

I actually just recently read a report from the late 80s that discussed a couple of scenarios and likely distribution of nuclear targets in each one.

The best case scenario (in the context of a full scale nuclear war with Russia) was a couple hundred successfully detonated strikes. The eastern seaboard, and all the metropolitan areas on the west coast were smoking holes in the ground. Pretty much anywhere with a sufficiently large military base, or significant government presence was on the "likely destroyed" list. There were a lot of random inland areas, which I assumed were targeting silos.

Basically, even in the 400 bomb scenario, the Boise field office of the IRS becomes the nation's highest authority.

Re:Nukemap by tablespoon on Saturday March 12, 2022 @12:53AM (#30649286)
> However, there are only 326 cities with over 100k population in the US. [1]

Only using an definition of "city" that's based on arbitrary political boundaries:

> This list refers only to the population of individual municipalities within their defined limits; the populations of other municipalities considered suburbs of a central city are listed separately, and unincorporated areas within urban agglomerations are not included. Therefore, a different ranking is evident when considering U.S. metropolitan area populations.

Metropolitan statistical areas are probably the right thing to count, and there are 358 of those over 100k (https://en.wikipedia.org/wiki/Metropolitan_statistical_area) in the US. Since US urban areas are pretty sprawling, you'd probably need multiple strikes to fully destroy most of the large ones.

When I way playing with nukemap, it looked like with a single air-burst bomb aimed the the urban core, the destruction of wooden buildings wouldn't even make it to the inner-ring suburbs.

Re:Nukemap by holtkam2 on Friday March 11, 2022 @03:20PM (#30645493)
Well Russia has about 6000 nukes so they could definitely afford to hit every major metro area in the west potentially dozens of times. Unless you live hundreds of miles from the nearest town I’d think it’s safe to assume you’d be dead, if not from a detonation from the onset radiation and / or climate catastrophe following the nuclear fallout
Re:Nukemap by dragonwriter on Friday March 11, 2022 @03:40PM (#30645725)
> Well Russia has about 6000 nukes

But closer to 1500 operationally deployed, and if they should launch any significant number of them, a substantial portion of the rest of the operationally deployed nukes in the world will be landing in Russia targeted and destroying any capacity they have to use any they have that weren't ready and deployed in the first strike.

Which is why if they use any significant number, even as a first strike, it will largely be for a counterforce strike doing the same thing to other nuclear powers, because who wants to be in a bunker without usable nukes when the guys you just nuked are in their bunker with usable nukes.

Having 6000 nukes ≠ 6000 nukes with operational readiness. If nuclear war were to break out, it is extremely unlikely that they could successfully use more than 1000 of those.

Not that that should make anyone feel any better about the situation, because even 1 nuke is too many.

Re:Nukemap by omdv on Friday March 11, 2022 @03:41PM (#30645731)
As Ukrainian, who was very (pleasantly) surprised at ineptitude of Russian military I changed my mind about nuclear war recently...

Of course hindsight is always 20/20, but even before the war I had the arguments with some of my friends that modern Russia cannot produce anything at a modern world class level. How it can be possible if they pay 40k RUB to Senior Engineers working in military or space organizations, while you can get 90k RUB working as a "Sales Consultant" in electronics store. Add to this the record levels of corruption; inept leadership being assigned because of their political affiliation, rather than knowledge and experience (just check Rogozin) and you will find hard not to agree with me.

This incompetence manifests itself at all levels - starting from glorious leader Putin, who managed to convert pro-Russian Ukraine into the "NATO state" in less than 20 years; secret agents, who cannot kill a person without leaving a radioactive trace throughout the whole country and the success of "military operation" we see now.

Anyhow, obviously I'd prefer not to test my assumptions, but I believe that Russia has no hypersonic missiles - they planned to have it in production in summer, 2022 and we know what it means in Kremlin-speak. So far it's all cartoons, like their new 5th-gen aircrafts and MBTs. And I am quite confident that the vast majority of their warheads and missiles are long gone...

Re:Nukemap by lostmsu on Friday March 11, 2022 @04:43PM (#30646391)

Re:Nukemap by AdamH12113 on Friday March 11, 2022 @03:44PM (#30645758)
It probably depends on how the war escalated to a nuclear exchange and whether it's a first strike or a second strike. In a first strike, the goal would be to take out the enemy nuclear arsenal as quickly as possible ("counterforce") to prevent retaliation, so in that case we would hope that all or almost all of the warheads would be targeted at remote missile bases. But you need a large number of accurate missiles to do that, so if you don't have those you're stuck targeting cities ("countervalue") for deterrence.

It doesn't seem like the U.S, Russia, or China have a hardline commitment to any particular response. If there are tit-for-tat attempts at limited escalation and deescalation, they need to be flexible.

Regardless, you need multiple warheads per target for reliability reasons, so if there's a massive nuclear war, you can probably expect a quick death rather than a slow one.

From my understanding (correct me if I'm wrong):

Bunker targets (mostly ICBM silos, heavily shielded targets like the bunkers under the White House, etc) would be targeted with a surface burst because bunkers would withstand air bursts.

Soft targets like airports, major cities, factories, ports, etc would be targeted using air bursts to maximize the destruction by preventing the shock wave and direct radiation from being shielded by geography and buildings.

There's a well known paradox in nuclear strategy where counter-force targeting is actually more "humane", but it requires the nation to keep more nukes in service.

On the other hand, a small stockpile will deter your enemy only if you are willing to use your stockpile on your enemy's population centers.

The US defense establishment believes the literal nuclear bombing of cities is an unlikely strategy. Russian first-strike strategy involves the usage of nuclear weapons for their Electromagnetic Pulse generating effects. The ability to destroy electricity delivery, generation, and electronic devices is just as likely to destroy or render ineffective an adversary's ability to respond as outright nuclear holocaust.

This document mentions that the use of high-voltage EMP bursts renders our nuclear arsenal vulnerable- those in silos, those in planes, and those in submarines if they are not sufficiently hardened against these attacks.

I am... dubious of the actual danger EMP poses to submarines. If they were surfaced, especially if they were attempting to recieve radio communications, sure. But a submerged submarine would be extremely well shielded.

The real question would be whether a submarine captain would be willing to press the button based on radio silence alone.

From the report linked, on the threat to communications between submarines and command, and the direct threat to submarines:

>> HEMP Threat To U.S. Submarines?

> HEMP attack could achieve for Russia a key objective the USSR could not achieve during the Cold War—neutralizing U.S. ballistic missile submarines at sea.

> Russian Super-EMP weapons could destroy or degrade U.S. bombers, ICBMs, SSBNs in port and their strategic C3I—including land-based VLF communications systems, TACAMO aircraft, and other redundant means of strategic command and control used to convey Emergency Action Messages (EAMs) to submarines hiding at sea. Severing their communications links to the National Command Authority would neutralize U.S. submarines, rendering them useless.

> HEMP could also be used to attack submarines on patrol at sea directly.

> A high-yield warhead (1 megaton or more) detonated for HEMP over the ocean would cover an area 2,200 kilometers in radius, a zone nearly as large as North America, with powerful E3 HEMP that would penetrate the ocean depths and possibly damage or destroy the electronics of submarines on patrol. Submarines would be especially vulnerable when deploying their very long antennae—which they need to do precisely when trying to receive EAMS.
