> designers, engineers and welders grapple with something the U.S. hasn’t done in decades: reliably shape hardened steel that is more than an inch thick into a curved, reinforced ship’s hull I don't understand. Aren't modern military ships armoured anymore?

The thick steel (like the landing deck of an aircraft carrier) is flat not curved. The curved stuff is actually Kevlar, not steel.

Didn't know they had kevlar hulls in WW2.

Do we really need to OWN icebreakers? Maybe we could start a website where countries and companies who own icebreakers can operate them for the benefit of other countries and companies who want to use them. They just walk to the shore in the Canadian north, click the "Call Icebreaker" button on the app and wait for an icebreaker someone else owns to arrive.

Generally speaking, states try to avoid having critical dependencies on other states, because they become points of leverage for adversarial foreign policy. For the purposes of keeping America running, yes, we really do need to own icebreakers in the same way that we need to own powerplants, steel mills, chip foundries and and refineries.

In this case though we're talking about Canada - the Canadian and US economies are incredibly linked. Personally, I'm a Canadian who makes money examining the US healthcare market and reselling that data to other Americans - there's lot of crossover here.

Two articles now I try to access the content at archive.ph and cannot make it past the Captcha. I've disabled uBlock Origin and that seems to make no difference. Is anyone else seeing this and if so, have a solution? (Firefox 117.0.1 (64-bit) on Debian Linux.)

Are you with Starlink by any chance? Had similar trouble from one of their IP's, but a different ISP's (same device) is working fine.

No, no amount of armoring is useful against modern weaponry, but it does increase the "m", thus lowering the "a" you get from your engine's "F".

Only the most vital parts receive some armor iirc. But not as thick as the armor found on the old battleships, and probably not curved.

Makes me wonder how much manufacturing knowledge has been lost in the west, and how long it might take to rediscover it all. Does anyone know of any good sources on this?

I remember a very old WSJ article about "swiss style machinists" and how there are no young American ones any more. This style of machinist makes tiny objects (think of how small things inside a mechanical watch are), where a day's production fits into a coffee cup. It takes a 10 year long apprenticeship to become productive enough that a company is willing to one of these machinists. All of the "younger" ones came from Germany or Austria because their governments subsidize the long training & apprenticeship programs. In the US, virtually all of them were laid off at the end of the Cold War.

Like most trade workers, the worker owns the tools that they use on the job. When they sell their tools, they leave the trade.

I don't think there have been any good studies or histories written about the decline in tradeskilled labor.

Meta: What is it about this post that attracted so many flippant comments? Non-meta: Why does the US have so few of these ships? Were more just not produced? I didn’t see an answer in the article but it’s possible I missed it.

Not a huge need, really just Alaska and the Great Lakes. For geostrategic purposes, our friends to the north have something like 20 including a couple heavies.

Interesting. I would have thought that the Great Lakes would be important to keep cleared and necessitate more than 1-2.

Surprise, this is what happens when you shift everything in heavy industry or production in general off to India and China without keeping at least some production domestic or at least have everything documented and regularly (i.e. once every ten years) check if the documentation is accurate and workers can understand it to build a product that meets specifications.

The U.S. doesn't have a centrally planned economy. Each business is free to do as it wishes... and if they wished to survive competitively, they moved their production offshore (helps avoid UAW strikes). Easy to know U.S. lost expertise, but tough question how do you get it back? Tariffs? A larger military-industrial complex? Even larger government?

> The U.S. doesn't have a centrally planned economy. Each business is free to do as it wishes...

Currently US federal government spending is around 36% of GDP, which means 36% of the US economy is in fact centrally planned, albeit with some devolution in some cases.

> Do we really need to OWN icebreakers? That would depend on one's strategic goals and priorities. Personally, I do not believe the US should be the world police so I don't think it is necessary.

OK, the who would you suggest should be the world's police?

The post-WWII world order is predicated on the agreement that the age of imperialism is over and that invasion by force to annex another country is illegitimate.

It is obvious that all nations do not agree to this. E.g.: China on Tibet, Taiwan, 9-dashed line, etc., Russia in Chechnya, Georgia, Ukraine. Those authoritarian states think it is perfectly fine to use force or threats of force to occupy & annex other territories and peoples.

The fact that we also have global shipping and travel at a relatively low cost (cheap enough to make & ship goods petty much anywhere-to-anywhere, and international travel is available to non-elites), is a direct result of US Navy keeping a lid on piracy.

Anarchy, or unpoliced random aggression would be a very bad option.

So, if the US does not do it, who do you think would do a better job, Putin, Xi, Kim, someone else?
