Honestly the loss of life is kind of horrifying. Especially when you consider the vast majority were unarmed transport ships of some kind. I cannot imagine slowly trawling along in some tanker when suddenly you're under fire from a uboat with no way to shoot back.

I feel like we're 'sleepwalking towards war' today with China over Taiwan (many top military brass have said they expect a war later this decade), and to be brutally frank, it's kind of insane to me that the powers that be have decided a mountainous island and some computer chips are worth the sacrifice of hundreds of thousands or even millions of human lives. I hope sanity prevails.

Russia has consistently used nuclear blackmail in Ukraine.

The West has responded with a very slow, incremental ramping up of aid to avoid triggering it.

If Russia didn't have nukes, the situation in Ukraine would look very different.

Nuclear blackmail is what stops NATO from ending the war overnight tomorrow with a massive air assault on Russian troops in Ukraine. Instead, we ship arms over the border and wring our hands with every small ratcheting up of aid calibrated to hopefully not trigger it.

Blackmail doesn't have to be perfect to be functional. The West has correctly assessed "they're not going to nuke us over x" so far, but it remains a consideration.

The current war situation is quite convenient for the US. They watch the Russians screw themselves up in Ukraine while mostly supplying it with aging weapons that were mostly sitting around close to being decomissioned. O handy way to get rid of old inventory and also to push Eastern European NATO members to update their stuff: donate your USSR-made scrap to Ukraine and we'll give/sell you more modern NATO compatible equivalents. Putin was dumb enough to start a war and enable this. And this time the US reacted with more than just sanctions.

The point of nuclear deterrent is to have it, not to use it. If one has too much of it they'll go bankrupt like the USSR. None and they'll get attacked or invaded. That's why nobody attacks North Korea and Iran mainly uses proxies to attack Israel.

I compare them with Israel, another small nation with high defense needs. They've spent less than 2% of their GDP on defense until very recently, they don't have a strong history of conscripting and training their civilian population. In short, they seem to have operated under the assumption that the united states would ride in to save the day.

I am a little sick of seeing the US, a country with two friendly neighbors, and massive oceans between us and our nearest peer adversaries spend ~ 1T / yr on defense to be the 'world's police'. The real threat to our security is at home.

Why is 2% a meaningful number? Less than that is insufficient and more than that is sufficient? Taiwan couldn't effectively defend itself against China regardless of how much it spends on defense. Nor could any other country on the planet except potentially the US.

Taiwan couldn't effectively defend itself against China regardless of how much it spends on defense.

They don't have to be able to defeat China to deter them, they simply have to make an invasion too costly to be worth it. Google porcupine strategy.

If Taiwan was serious about their defense, they would have a higher percentage of their population conscripted and trained for longer. They would have been spending a much higher proportion of their GDP on defense. The fact that they've done neither of these things tells me they're passing the buck to us and expecting the US to pay the cost (in both money and lives) of their defense, and I don't think we should.

If you think the US isn't a major beneficiary of global peace and open trade, you are very mistaken.

You don't think the world had free trade before US hegemony? The truth is that other countries would step up and help shoulder the burden instead of simply relying on us to do everything.

I'm extremely doubtful of the benefit to the average us citizen of the tens of trillions of dollars in us military expenditures since WWII. I think we would find ourselves in a more stable, prosperous country had we spent that money on education, infrastructure and healthcare.

Regardless, I'm not interested in continuing this conversation further. We're not going to change each others minds.

Again, what benchmark are you using to assess the sufficient level of deterrence, GDP ratio, or conscription?

As far as I can tell, we have solid empirical evidence that those things are sufficient, based on the fact that China hasn't invaded.

That seems to be the recent business plan of the military industrial complex. Wars aren't popular among US voters, and military recruitment numbers are struggling. Instead, if we sell slightly dated weapons to foreign armies then the money keeps flowing into our war economy.

I think this strategy will only work because of MAD, and it's essentially a modification of our previous proxy war strategies that existed prior. It has several risks and benefits. I'm worried that the separation Americans feel (we aren't at war, one of our allies we are heavily supporting is) isn't the same level of separation that the other side of the conflict feels. I'm worried that some of these allies will be manipulated into conflicts in order to generate customers. I'm worried that if our soldiers are needed too many of them won't have combat experience, which improves their effectiveness. I'm worried that the loss of life will have less of an emotional impact when it's happening to other people far away.

The benefit of not risking American lives while still maintaining cashflow for weapons R&D is massive though.

It can be said as well that war between China and the Philippines may break out even before that given their current encroachment on a number of strategically important shoals in the South China Sea.

Things are escalating in a very scary direction between the two countries coast guards.

That being said the Pacific has not changed in the last 80 years and it will still be eerily similar to the naval escapades seen then - but I anticipate with far greater loss of life despite autonomous capabilities (due to range of weapon effectiveness and lethality of munitions).

A long time ago I was a Merchant Marine cadet. One of the classes we had to take during senior year was on working with the Navy during conflict/all out war.

As we were working through the Convoy Operations unit, I remember thinking that it was basically bullshit. You're in a group of other merchant ships being protected by the US Navy, but the maneuvers were based on an enemy with a WW2 level of technology. If you are attacked by any modern force that somehow managed to get through the outer ring of defense, as a merchant vessel, you might as well start lowering lifeboats.

For context, the contemporary commercial merchant fleet is about 80,000 ships, roughly a third of which are bulk liquid carriers (a/k/a oil tankers). As a percentage, that's actually down from the 1970s/80s when half of all commercial ships were tankers. Most of the growth has been in container ships.

Relevant to WWII, oil tanker losses by the US alone were staggering. "A total of 129 tankers were lost in American waters in the first five months of 1942." (<https://warfarehistorynetwork.com/article/operation-drumbeat...>).

A consequence was the US government building the first long-distance oil pipelines, the "Big Inch" and "Little Big Inch" pipelines from east Texas to refineries on the Atlantic seaboard in New Jersey. They remain in use.

<https://en.wikipedia.org/wiki/Big_Inch>

I've also realised that both whales and large-scale commercial shipping rely on similar circumstances: the ability to on- and off-board cargo (or food) rapidly, widely-separated ports (or feeding grounds), and no significant predators (or war / piracy hazards). Whales are a remarkably recent evolutionary development, with the large great whales dating back only about 5 million years. Similarly, bulk shipping required not only global markets but cargos which could be handled in aggregate, whether liquids (as with petroleum), dry solids (mostly ores), or containerised miscellaneous cargo, the latter being premised on standardisation. Canals, safe shipping routes, and quayside cargo handling capacity were also prerequisites.

There were certainly groups in the services in WW II who suffered much higher casualties. For example, flying in a bomber crew was very dangerous. I can't quickly find some complete stats, but for example in 1943:

During 1943, only about 25% of Eighth Air Force bomber crewmen completed their 25-mission tours—the other 75% were killed, severely wounded, or captured.

See my comment above. Total air crew and merchant-marine sailor contingents were likely somewhat comparable.

The US built ~35k bombers during WWII, generally with large crew sizes: 8 for the B-24 Liberator (18,118 built), 10 for the B-17 Flying Fortress (12,731), 11 for the B-29 (3,970). That's ~35k aircraft, which would have required at least 3,500 crew members, and probably a multiple of that (presuming several crews per aircraft to sustain multiple missions).

That does make the bomber crew contingent itself smaller than the merchant marine, and air losses seemed to be concentrated among bomber crews, which were larger, slower, and generally more vulnerable than fighters or fighter-bombers.

dredmorbius

Trying to back out numbers here ...

I don't find a total size of the US Army Air Corps' European flight crew operations, but I do find a casualty count of 70,000 (<https://www.nationalww2museum.org/war/articles/black-thursda...>). If that constitutes 75% of the total force size, then we come up with a total force size of 93,333. Let's call that 100,000.

For the merchant marine:

During World War II, nearly 250,000 civilian merchant mariners served as part of the U.S. military and delivered supplies and armed forces personnel by ship to foreign countries engulfed in the war. Between 1939 and 1945, 9,521 merchant mariners lost their lives — a higher proportion than those killed than in any military branch, according to the National World War II Museum.

<https://www.defense.gov/News/News-Stories/Article/Article/30...>

The US Army Air Corps trained 435,000 pilots during WWII, with more trained by the US Navy and Marines.

"WWII’s Tragic Aviation Accidents", Warfare History Network (2018)

<https://archive.is/718ZJ#selection-671.287-671.295>

The US Navy reports 5,563,507 officers and 6,570 enlisted (totals are regular and reserve), presumably aviation, with 12,133 total fatalities, of which just under 30% were combat deaths. (The remainder were largely non-combat crashes.)

<https://www.history.navy.mil/research/library/online-reading...>

(The total officers count seems suspiciously high, and I suspect is for the total Navy corps, rather than just flight operations.)

And about 15,000 pilots died during training.

<https://www.realclearhistory.com/articles/2019/02/12/stagger...>

This still doesn't break out bomber crews relative to the overall US air operations, but at least for ballpark estimates, it seems that air crews and merchant sailor contingents were at the very least comparable in size, if not more air crews. That makes some sense as ships would be larger, fewer in number, and with a more efficient use of personnel (in terms of crew to net operations and tonnage delivered).

Another triangulation: the US produced about 300k combat aircraft, and about 35,000 bombers, during WWII:

<https://en.wikipedia.org/wiki/United_States_aircraft_product...>

(The story of industrial production and scale at which the US poured out materiel, whether ships, tanks, fighters, bombers, or what have you, during WWII, is worth its own discussion.)

I'm actually surprised the losses were so low. Obviously 4% is dramatically higher than your chance of death in other jobs but it's still quite low (e.g. when I'm playing X-COM I feel like the computer is cheating when I miss a 96% shot). I would have thought that in going to war, especially one as deadly as WW2, you'd at least have a double digit chance of dying.

The US submarine warfare operation in the Pacific was also absolutely devastating to Japan, particularly as that country has virtually no indigenous mineral or energy resources.

A large part of Japan's invasion of China (from whence it could reasonably readily ship resources) was China's own mineral supplies, particularly coal an iron. For petroleum though the nearest viable source was Indonesia (then the Dutch East Indies), and the US sank much of what moved from there.

This fact, as well as my parent comment above about U.S. east-coast oil shipping and pipeline construction are quite well covered in Daniel Yergin's book The Prize. If you want an appreciation for just how much oil transformed the US and world, it is an absolutely excellent resource. And that's from someone who's not partial to Yergin's oil-industry boosterism.

Corollary: one reason we see a mismatch here in modern days is the long term effect of the Jones Act.

It's illegal for a non-US flagged ship to go between two US ports, so we see more done by train.

This was Texas (and perhaps Oklahoma and Louisiana) oil. Texas alone produced a huge fraction of the oil used by all parties during WWII, with Russia being the other major supplier.

Texas oil shipped from Gulf of Mexico ports (probably Port Arthur, though there may have been others), around Florida, and up the East coast of the US, principally to New Jersey where the major East Coat refineries were. Probably Bayway Refinery, owned and operated by Phillips 66.

There was no significant oil transport around South America so far as I'm aware. West-coast oil was supplied out of California, presumably the Pacific Theatre as well.

My recollection is that they did use trains, at least during the worst parts of the war. (In terms of tanker losses & shortages.)

But an oil tanker is vastly more efficient than train full of tanker cars. And the supplies of tanker cars, rail lines, locomotives, & etc. were all pretty constrained.

Yes, though the contemporary fleet moves a lot more cargo than the WWII era fleet, as the ships are a lot bigger, somewhat faster, and thanks to containers and ro-ro ships cargo handling is a lot more efficient so the ships spend much less time in port unloading and loading.

Thanks for asking, as I seem to have misremembered (and inflated) my earlier source, and have pulled in fresh data.

My source was the UN Trade & Development organisation's Review of Maritime Transport 2014, which I'd looked up a ways back for an earlier essay.

Turns out I'd misremembered the size of the shipping fleet as of 2014, it was 47,601 ships, not ~80k, though that makes my point on this thread all the more apropos. I suspect I'd turned up the ~80k figure (if I recall, slightly less than, in the 70--80k range) from that or another source, and current fleet size is somewhat above that, keep reading. It should be remembered that current ships tend to be far larger than those of WWII, with the 2014 fleet totalling 1.68 million deadweight tonnes (DWT), or about 35 DWT on average. That's ... still lower than I'd have thought, as, for example, a Maersk E-Class container ship weighs in at 158,200 DWT,[2] and the largest oil tankers range up to 550,000 DWT.[3] From my sources earlier in this thread, WWII ships tended closer to 10,000 DWT.

The 47,601 ship number comes from summary line of the table on page 37 of the 2014 report, and applies to ships of 1,000+ DWT:

<https://unctad.org/system/files/official-document/rmt2014_en...>

Full report: <https://unctad.org/system/files/official-document/rmt2023_en...> (PDF) (English)

From that:

In January 2023, global maritime trade was transported on board 105,493 vessels of 100 gross tons (GT) and above, with oil tankers, bulk carriers, and container ships accounting for 85 per cent of total capacity.

My dad served in the Merchant Navy in WWII and narrowly escaped death more than once. I don't recall the details because I was too self absorbed as a young man to pay sufficient attention to his stories. Which astonishes and shames me now, nearly 40 years after his death.

The source I'd relied on for the 80k ships figure actually reported 47k ships, as of 2014.

The latest estimate, from the same source, is 105k ships of 100 deadweight tonnes or greater.

On a related note: Those ships are highly sought after. At some point there will probably a startup using this data to salvage all these ships.

Why? Because it was before the nuclear bomb and all the other desasters that followed which actually permanently raised our background radiation levels. And because these ships were and still are underwater, they have been largely unaffected by this.

It might not seem much but apparently the radiation difference is enough, so for things that go into your body (like after an operation) only this old steel is used.

Or so I was told by a friend working in medical.

When you turn iron ore into steel with blast furnaces and steel making (e.g. basic oxygen process) you blast it with atmospheric air (or oxygen made from atmospheric air), and tiny amounts of impurities in the air (such as fallout from atmospheric nuclear testing) get embedded in the steel.

Yes, this is the same air you're breathing. No, the levels are not high enough to be a health issue. But it's an issue for very sensitive scientific instruments and such.

Also to note that, in theory, you could use purified oxygen for the forging and create new steel similar to low-background radiation steel, but it would be ridiculously expensive given how much oxygen is used.

Steelmaking is the combination of iron ore and carbon (from coked coal) with huge amounts of forced air or direct oxygen to form the alloy of carbon and iron we call steel.

One notable form of radioactive contamination is Carbon-14, which is what makes radiocarbon dating after ~1950 unreliable. Though of course since the carbon in coal is itself primordial, that isn't the principle route of steel contamination.

Best I can make out it's radioactive isotopes in the air itself which increase the radiation background of post-WWII steel, with several sites mentioning Cobalt-60. Substances used in the post-smelting processing of steel (welding rods and the like) may also introduce contamination.

Given the 1963 Partial Test Ban Treaty which has halted most atmostpheric nuclear testing, radiation levels have fallen to the point that current steel is largely similar to pre-WWII "low-emissivity" steel in terms of background radiation.

It's because the smelting process introduces a lot of isotopes into steel when you make it.

I assume that they find big pieces of already smelted steel in the ocean and just grind away the rust / mill it into the shape they want.

It was a thing.

https://en.wikipedia.org/wiki/Low-background_steel

Since we've stopped nuclear testing, though, it's returned pretty close to normal, and such steel is no longer as sought after.

World anthropogenic background radiation levels peaked at 0.11 mSv/yr above natural levels in 1963, the year that the Partial Nuclear Test Ban Treaty was enacted. Since then, by about 2008, anthropogenic background radiation has decreased to 0.005 mSv/yr above natural levels.

By your logic, any random long-urbanized space on Earth should remain untouched because at some point it was the site of people's (often violent) deaths. These ships weren't memorial vessels, they were just ships doing work and there's nothing wrong with salvaging them. Cemeteries are a different story. They represent places where people specifically chose to bury their dead for the sake of memorializing them.

Nah, they don’t use low-rad steel for medical implants. Mostly for scientific instruments that would thrown off by even a small rise in background radiation.

IIRC the bulk of the supply came from the scuttled German fleet at Scapa Flow, where the ships involved were not graves - they were intentionally scuttled by the crew, who got off and were rescued.

In the NYT story, it makes much more sense (also the way it's implemented is far less offensive). It makes sense because it was trying to tell a story, and the slide show gives more emotional impact to it. That's cool! I still don't like it and would prefer just the story, but I see why it makes sense here.

however, when you're trying to convey information, this style of page is offensively bad and I doubt is really doing you any favors - inline images and videos do the exact same thing you're trying to accomplish here without all the obnoxiousness.

There is a clear inflection point around March 1943: From this point onward, the Allied forces sank more ships every month than they lost.

If you look at the graphs there is nothing like an 'inflection point' or qualitative change in the graph behaviour.

The Allied line goes slowly down and the Axis line goes slowly up. At one point they cross, but there's nothing particularly significant about that crossing point. Nothing happened in the month that they crossed other than the two numbers were equal momentarily.

Supposedly the better question is why it took so long for an allied victory. Britain’s economic output was absolutely vast, and its colonies made it very powerful. Yet it still took the US industrial capacity coming online and a significant portion of the USSR’s population dying before victory.

It's a silly thing to say, because ship losses are largely driven by German submarines in the Atlantic and American submarines in the Pacific, which are about as disconnected as things get in WW2.

You can see clear trends in the data in each of those theatres, both of which turn drastically in the Allies favor later in the war. The main driver for that is American war materiel production, but there's also plenty of decisions in strategy, tactics, and weapons systems that are entirely different.

May of 1943 was called Black May because so many U-Boats were sunk, 25% of the force.

It's surprising to me how few ships seem to sink out in the open ocean where it would be nearly impossible to ever recover or research their wrecks.

Does anyone know to what degree modern ships tend to hug the coast on their trips? My understanding is that until relatively recently (maybe the last 500 years or so?) almost all sailing was coastal and it was mostly unheard of for anyone to venture out into open ocean. However, I don't know to what degree that's still the case. E.g. if a modern ship is traveling from from somewhere in Asia or Europe to South Africa do they plot a relatively direct route or do they tend to hug the coast?

That's mostly a function of which ports ships travelled between, various choke points (particularly straits and canals), and Great Circle routes.

As an example, shipping traffic between Long Beach (Los Angeles, CA, USA) and Shanghai, China, doesn't head straight out into the Pacific, but hugs the west coast of North America, the southern coast of Alaska, the Aleutian Islands, and threads through the Japanese archipelago, not because today's container ships fear the open ocean and cannot navigate across it, but because that is the shortest route, following a Great Circle from Los Angeles to Shanghai. Similarly, Atlantic traffic between New York and Britain travels significantly further north than one might expect.

WWII saw little US-China traffic, but a great deal of US-UK traffic.

Sea traffic generally would have been concentrated along major supply routes. US-UK, as noted, Japan-Indonesia, and along the Atlantic and Mediterranean coasts of Europe and North Africa. Venezuela was another major oil hub, and Japan was sourcing materials from occupied China and Indonesia.

There's also logistics for attackers: it's militarily advantageous to strike within target-rich environments (where there's a lot of traffic), where the opponent cannot defend or strike back, where traffic tends to be concentrated (straits, islands, port mouths, around islands), within range of a home base or resupply network (the US's western Pacific operations are a solid indicator of just how robust the US logistics chain was, to permit operations over 8,000 mi (13,000 km) from West Coast ports), etc. Hanging out in mid-ocean waiting for the stray target to come into view makes little sense.

Even today, many shipping lanes tend to follow or be shaped by coastlines, see for example:

<https://www.visualcapitalist.com/cp/mapping-shipping-lanes-m...>

That map doesn't do justice to the tremendous traffic from China via Suez to Europe, or the massive amounts of South China Sea traffic, though at least the general routes are evident. It also cuts the US-China route in two by way of the map projection.

Also of interest are the two dots off the mid point of the west coast of Australia, one green for "non combatant merchant" one red for "armed warship".

The reality is that the heavily armed "merchant ship" Kormoran was a stealth convert by the German Navy and generally referred to as the German auxiliary cruiser Kormoran.

The Kormoran was approached by the RAN warship HMAS Sydney for signaling and inspection, figuring that its game was up it unloaded everything it had fatally damaging the Sydney and taking on terminal shelling in the process.
