USA Gives South Korea Green Light to Build Nuclear Submarines

Brilliant move. Giving South Korea the U.S. approval required to provide for its own defense, while using that to incentivize investment into American shipbuilding.
echelon•50m ago
That's a genius move!

We should get every country to do this.

Build your nuclear subs here, in the US shipyards. We'll help you!

We can massively expand our capacity, which will be important for self defense in the coming decades.

tyre•8m ago
An interesting example of this is the US modernizations of its military industrial capacity by supply pre- and during WWI. There was intense debate in the international community as to whether non-warring countries could supply nations at war without being considered combatants.

If they aren’t, you can’t neutralize the enemies supplies. If they are, those third countries are effectively part of the conflict.

The US had to take the latter stance because it didn’t have a strong industry to product its own weapons. If it supported nations from buying from non-warring parties, it would be shit out of luck if it had its own wars. So it received a lot of investment from European powers, generating jobs, economic growth, and the funding to expand its domestic production without having to take on debt or wait for a war to break out.

Come its entry into WWI and then WWII, the US had a strong home base of industrial capacity for arms manufacturing.

farseer•51m ago
South Korea is capable enough to build nuclear submarines even if the US had denied them the said facilities. This saves them money, not having to modify their shipyards.
echelon•48m ago
It's really great for the US to have customers. We can expand our shipyards again.

We should go and find more customers.

JumpCrisscross•47m ago
> South Korea is capable enough to build nuclear submarines even if the US had denied them the said facilities

Technically, yes. Politically, no.

“To produce fuel for the submarines’ naval propulsion, the ability to enrich uranium was required. However, this plan probably served two goals, since a country with enrichment capability can also enrich uranium to weapons-grade levels without significant difficulty. The fact that [former President Roh Moo-hyun] launched this plan less than five months after North Korea’s [2003] withdrawal from the Non-Proliferation Treaty (NPT) supports the possibility that his ulterior motive was to acquire uranium enrichment capability in part to enable the future development of nuclear weapons. Ultimately, Roh had to abandon this plan in 2004 amid rising suspicion of South Korea’s nuclear ambitions after the International Atomic Energy Agency (IAEA) discovered that South Korean scientists had previously conducted an unauthorized enrichment experiment” [1].

What am I missing about how hard it is to enrich uranium? We did it in the 40s, having a significantly less solid understanding of all of the physics involved. Material science on containers, motors, energy generation, etc have all been significantly improved in the intervening decades.

Wikipedia says U235 is ~0.7% of earth deposits, and as little as 7kg may be required for a minimal nuclear device. Processing, 700kg of uranium does not sound insurmountable, even with a terribly slow and inefficient process. Just grinding it up and using some kind of mass spectrometer could trivially separate a 3Dalton mass difference.

JumpCrisscross•20m ago

There was no NPT in the 40s. And we weren’t technically at war with a nuclear-armed Canada backed by a pro-NPT international alliance.

I mean Iran is certainly managing it, so I think it's mostly a political will / will this get you attention and coup'd thing?
tyre•1m ago
It takes a lot of centrifuges to refine the amount and, more importantly, the purity of fissile material. By the time you need them, it would take a long time to spin up that infrastructure and iron out the kinks.

It’s not a casual undertaking and other nations will know you’re doing it. The major global powers are not interested in more nuclear weapons, not only to maintain their hegemony but also to limit the number of parties that could cause massive issues. Not to mention the likelihood that a national or political shift could mean nukes in the hands of those less…restrained.

Plus it raises the surface area of others gaining access to the material or capabilities. Proliferation is bad for the world, generally.

The US has an incredibly strange relationship with shipbuilding.

Zvi and the Cato institute both have lengthy pieces about why the Jones act is bad [1] [2], and whether or not you believe that has entrenched our shipbuilders, the US essentially manufactures no ships compared to South Korea and China.

This naval news post says there are $5 billion in modernization costs for the shipyard needed for this project so it seems like we're still years away from a started (much less completed) project.

Maybe we can buy some of these South Korean nuclear submarines, park them off the coast of the US, and use them for energy. If we do it quick, we might be able to get nuclear power going before the environmentalists notice.

Edit: Your downvotes only make me more powerful.

nemomarx•18m ago
Why would we buy south korean subs for this, especially ones south korea is building with us navy help? we have nuclear subs and the us is actually pretty good at building more of them. It's the cheapest kind of reactor we have and doesn't get protested by environmentalists.

The transmission from sub / ship to shore is not great I think, though. They're used for power during disaster recovery?

hearsathought•35m ago
Imagine if south korea needed china's permission to build nuclear submarines. We'd called them china's vassals and attack china for being bullies who deprived nations of their sovereignty.

Imagine if the title was : "China Gives South Korea Green Light to Build Nuclear Submarines".

What would the comments here be like. No doubt a lot of nonsense about "the ccp" this and "the ccp" that.

Glyptodon•27m ago
I will say that the "in/on US territory" piece is a very key detail.

Like obviously no matter the country, if you want to build weapons offshore in their territory you probably need permission.

hearsathought•23m ago
> I will say that the "in/on US territory" piece is a very key detail.

That's the point. South korea is not allowed to build nuclear submarines in their own territory. They lack the sovereignty to do it. The US won't give them permission to build one on their own.

But you probably knew this and your comment is meant to distract.

cookingmyserver•19m ago
Citation needed. I am unable to find any treaty that prevents the RoK from building nuclear submarines on their own territory.
hearsathought•15m ago
> Citation needed. I am unable to find any treaty that prevents the RoK from building nuclear submarines on their own territory.

Are you being intentionally dense? Why wouldn't they be building it in their own territory if nobody was stopping them?

Besides, I already replied to your other comment that South korea is not allowed to enrich uranium by the US.

IncreasePosts•8m ago
> Why wouldn't they be building it in their own territory if nobody was stopping them?

Because they don't have the facilities to build a nuclear sub, and America does, since America has built over 200+ nuclear submarines in the past?

Building a nuclear sub, and fueling it, are two separate things.

cookingmyserver•3m ago
No, I am not being dense. From your continued lack of citations I am starting to assume there is no law stopping the RoK from enriching uranium (though I have been trying to find one). Uranium enrichment facilities are expensive. If you have a partner nation who is willing to sell you the enriched uranium that just makes sense. Again, it being the property of another nation, they have the right to judge who should have access it it and what they might do with it. If RoK wanted to spend a percentage of their GDP on enrichment facilities they could. They don't have an urgent reason to. Further they don't have any deposits of any uranium to begin with so they would still need to partner with another nation anyways, so I ask you - Why would RoK want their own enrichment facilities?
OneDeuxTriSeiGo•4m ago
That's just not true? South Korean ministers have been discussing building nuclear submarines domestically long before this current agreement.

And the US has an agreement with South Korea that limits domestic production of fissile material for military uses but it's a mutual agreement that we have with a bunch of countries (including China) and is essentially always renegotiable as situations change. Essentially it's just an explicit agreement of how much material a given country intends on producing for the purposes of requiring public political discussions domestically before ramping up production.

That is all very much a flexible situation and the US doesn't have any actual power to legitimately stop South Korea from manufacturing domestic nuclear reactors for military purposes.

That's why reading comments about geopolitics on the Internet is largely useless. Big news! A country's population supports its own country on international stage! If you go on Chinese social media, it'll be mostly about how awful the Americans are, and vice versa if you are on Reddit for example. So what is even the point of reading them, anywhere..
mh-•16m ago
I think you and I are on very different Reddits, if you're using it as an example of pro-American social media.

Fully agree that reading either for geopolitical opinions is useless.

cookingmyserver•22m ago
I don't think any country has the right to demand that another country hands over enriched uranium and allow them to move into a shipyard so that they could build a nuclear sub. Of course you need permission from a seller to buy products and use their facilities. I would recommend going beyond simply reading the headline.
hearsathought•19m ago
> I don't think any country has the right to demand that another country hands over enriched uranium and allow them to move into a shipyard so that they could build a nuclear sub.

The US won't allow south korea to enrich uranium on their own. Want to try again?

> I would recommend going beyond simply reading the headline.

Another intentional distracting comment.

The US invaded South Korea, had and still has massive influence on their government, has military bases there. It’s just polite fiction to ignore the fact that South Korea is a US vassal. Makes US look better in the media, etc.

The treaty restricting Korea is the Treaty on the Non-Proliferation of Nuclear Weapons [1]. America is giving Seoul a loophole by offering to do the NPT-governed work.

Can you stop with the nonsense already. It never ends with you.

> The treaty restricting Korea is the Treaty on the Non-Proliferation of Nuclear Weapons [1].

Or maybe Korea could be like India, your native country, and not be part of it.

> America is giving Seoul a loophole by offering to do the NPT-governed work.

Yeah, a loophole seoul doesn't need. You act like america is doing korea a favor. All this does is make korea even more dependent on the US. Even more of a vassal.
