    The cost of a B-61 nuclear gravity bomb is only $28 million (2012). There are approximately 400, of which 100 were moved to Europe in 2022. They can only be launched by an F-18 or F-35 with a special armament control package (not included in the $28 million).

    $28 million gets you spin rocket motors that improve accuracy to within 10 meters, and internal and celestial guidance. The yield is variable ("dial-a-yield") (10-340kt) to allow selecting the amount of tritium for the explosion.

    The cost for an F-22 is $191 million (2023). A B-2 is $2 billion.

            And we bought 21 of them. So $42 billion for the airplanes. This figure does not include operational costs such as training, fuel, maintenance, etc.

              And we somehow managed to crash two of them - on takeoff. Like literally, while taking off. No deaths, thankfully, except for the pilots souls.

              In the first case because of - wait for it - rain. [https://en.m.wikipedia.org/wiki/2008_Andersen_Air_Force_Base...]

            Well, it cost more to design and build.

            I personally would consider the total cost of dropping two atomic bombs much higher, for hopefully obvious reasons.

            EDIT: Although, per the article, I might have been wrong about that:

            > The loss of life was shocking. The B-29 raid on Tokyo on the night of 9 March 1945 is thought to have killed as many as 100,000 people, making it more destructive than either of the atomic bombs that were to follow.

            Fascinating bit of history though, thank you for sharing.

              The US's conventional bombing raids on Japan were extensive - they had all but destroyed most Japanese cities by the time the nuclear bombs were dropped. Hiroshima and Nagasaki were not large and notable Japanese cities, but they were among the only ones left by that time.

              • tgv a day ago

                Spared, even. There were more selection criteria, though, and Nagasaki was (IIRC) chosen at the last moment because of the weather.

                  Kokura was the primary target and three bombing runs were made before diverting to Nagasaki.

                      It’s a bit worse as they were the only ones left because they were purposefully saved knowing the nukes would need a target.

                          Wikipedia claims Hiroshima was saved for atomic bombing, about a month ahead:

                          > On 3 July, the Joint Chiefs of Staff placed (Hiroshima) off limits to bombers, along with Kokura, Niigata and Kyoto

                          Nagasaki was not explicitly saved, but was just a difficult target to hit:

                          > Nagasaki had been spared from firebombing because its geography made it difficult to locate at night with AN/APQ-13 radar.

                          > Unlike the other target cities, Nagasaki had not been placed off limits to bombers by the Joint Chiefs of Staff's 3 July directive, and was bombed on a small scale five times.

                            July 3 was one month prior to the nuclear bomb dropping. By that time, B-29 bombing raids with conventional bombs had been operating since 1944. Further, the fact that they had to order it to be preserved on July 3 implies that it hadn't been saved until that point. So, Hiroshima was saved for a month, but only after it had been an equally viable target for the prior several months to a year.

                            Between May and August 1945, US bombers dropped an average of 34,402 tons/month of bombs on Japan. This would have reached 100,000 tons/month by September, 170,000 tons/month by January 1946, and 200,000 tons/month by March 1946.

                              The atomic bomb was more of warning and show of force to the Soviets rather than the Empire of Japan. The purpose of the bombs wasn't (just) to get Japan to surrender, since they were already near defeat anyway, it was to show the Soviet Union that the US had the wonder weapon already working and that they should back off and fall in line unless they want a piece of that. I think many people miss that part of history.

                                There was plenty of fight left in Japan. The battle of Okinawa was absolutely horrific and small a scale guide to what invading the homeland would have been.

                                There were 76,000-84,000 allied casualties and 105,000-110,000 Japanese. The civilian death toll was 40,000-150,000.

                                Claiming that lives were saved by bombing cities with nuclear weapons is always going to be a hard one to prove and morally dubious, but it might also be correct. https://en.m.wikipedia.org/wiki/Battle_of_Okinawa

                                  After the first dropping, the War Cabinet met on August 9th and concluded in the morning that the US probably did not have the resources to build more than one bomb, and it was decided to keep fighting.

                                  Then in the early afternoon they learned of the second dropping. After further debate the War Cabinet voted 3-3 on whether to continue fighting.

                                  It took two bombing to get to a tied vote (both of the War Cabinet, and the full cabinet): the Emperor had to be called to break the stalemate. I do not understand how anyone could believe zero bombings would result in a cessation of hostilities.

                                  And even after the decision was made, there were still attempts to prevent surrender:

                                      I suppose there were some coups that succeeded because the plotters controlled the news media.

                                        And military action against government wasn't a new thing in Japan either:

                                        > Prime Minister Inukai Tsuyoshi was assassinated by 11 young naval officers. The following trial and popular support of the Japanese population led to extremely light sentences for the assassins, strengthening the rising power of Japanese militarism and weakening democracy and the rule of law in the Empire of Japan.

                                    I'm not a historian but I've always read that the Japanese government famously did not intend to surrender despite being cornered.

                                    They had some operations scheduled for October 1945—they surrendered 1 month before due to the bombs.

                                      The Japanese government didn’t have any intent to surrender until the emperor at the time asked/told them to.

                                      I’m fairly certain that happened after the bombs.

                                      Then they suggested they’d surrender if the poition of the emperor was untouched.

                                        Didn't the Soviet invasion of Manchuria also boxed them in? Some Historians(Paul Hamn for once) have said that was the primary reason for the surrender.

                                          Manchuria was across the Sea of Japan from the Japanese home islands. The Soviet invasion of Manchuria did nothing substantive to directly threaten Japan.

                                          Japanese strategists wanted to be in Manchuria and Korea because of their proximity to imperial Japan, but that was also why they had invaded the Philippines (to defend seaborne lines of communication to their oil supplies in Borneo).

                                          By the time the Soviets invaded, the Japanese had been ejected from much of their outlying empire, yet they had not surrendered, because Japan itself had the capability to fight.

                                          The Soviet invasion of Manchuria did not change that, an invasion of Japan proper could only have come with involvement from the rest of the allies, including the sealift used for the invasions of Normandy and southern France.

                                            The Japanese were already expecting a Soviet attack: the only 'unexpected' thing about what the Soviets did was make a move in Summer 1945 instead of Spring 1946.

                                            But the Japanese knew what was going to happen eventually.

                                                The Soviets could never have done a large invasion of Japan. They had a few ships that the USA had given them as part of Project Hula, but that is nothing compared to what would be needed for a full scale invasion of Japan. They did have plans to possibly attack Hokkaido, but as the wikipedia entry says "Historians have generally considered it unlikely that an invasion of Hokkaido would have succeeded."

                                                In comparison, the proposed allied invasion was planned to have 42 aircraft carriers, 24 battleships, and 400 destroyers and destroyer escorts. Even that wasn't considered enough:

                                                    The Japanese had already moved all of their experienced troops from Manchuria before the invasion. They were surprised that the USSR would break the Soviet–Japanese Neutrality Pact, but the defense of the home islands was their main concern at that point.

                                                    As your source says:

                                                    >...The Soviet entry into this theater of the war and the defeat of the Kwantung Army were significant factors in the Japanese government's decision to surrender unconditionally on 15 August, as it became apparent that the Soviet Union had no intention of acting as a third party in negotiating an end of the war on conditional terms.

                                                    The Japanese knew the USSR was not a threat to the main islands and the USSR knew they would likely fail if they tried to invade Hokkaido. The Japanese had hopes that the USSR would be willing to negotiate with the Allies on their behalf, but once the Soviets declared war was, they knew that would not happen.

The US and Soviet Union would have leveled Japan without atomic bombs anyway. So the US history stories puts the success of the end of the war on the atom bombs, but Japan were defeated anyway, atom bombs or not.

                                                  As in, Kamikazis because ordered, honour in death, or killing yourself with your own sword. Not really a culture of capitulation. Most of their cities were already firebombed, as you elude to, some more than once, yet there was still no surrender.

                                                  Without surrender, a country isn't really done. Leave it be, and they'll arm and rebuild, still at war with you. Invade, and your troops die, for a standing army still existed. Japan also had colonies, islands, resources.

                                                  And of course without surrender, even if you occupy, now you have insurgents.

                                                  It's hard to view the world through the eyes of even 80 years ago.

                                                      Of course, after surrender, a country can still arm and rebuild, and again be at war with you...

                                                      And even with the atomic bomb, and Russia's declaration of war, they still had an attempted coup to keep the emperor from surrendering.

                                                      Two history books, "Code-Name Downfall" by Allen and "Downfall" by Frank point out that the Japanese high command was horrified by the effects of the nuclear bombs, cared a great deal about the loss of life, and were highly concerned that the next target would be Tokyo.

                                                      So they chose to end it.

                                                      There's a fair amount of detail and references in those books if one wishes to dig into it.

                                                      (I say they are "history" books as opposed to "activist" books. The latter are not worth reading.)

                                                      Some material I've seen claimed that the Japanese leadership didn't know it was a nuclear bomb. The Japanese knew immediately it was nuclear bomb, because they had a nuclear bomb development program themselves.

                                                      • themaninthedark a day ago

                                                        I think the material that claims the Japanese leadership didn't know what atomic bombs were is some revisionist's attempt to paint the actions and decisions of the time in a bad light. Fortunately, the emperor referenced atomic bombs in his surrender speech so it is fairly clear.

                                                        "Furthermore, the enemy has begun to employ a new and cruel bomb, causing immense and indiscriminate destruction, the extent of which is beyond all estimation."

                                                        Japan had no idea how many bombs we had and part of the strategy of using them in quick succession was to give the perception that we hod more than we did. It seems like Tokyo was going to be the next target:

                                                        Truman had ordered a halt to atomic bombings on 10 August, upon receiving news that another bomb would be ready for use against Japan in about a week. He told his cabinet that he could not stand the thought of killing "all those kids". By 14 August, however, Truman remarked "sadly" to the British ambassador that "he now had no alternative but to order an atomic bomb dropped on Tokyo", as some of his military staff had been advocating.

                                                          Yeah, it was in an activist's writings someone was using as a cite to me. Tells for an activist book:

                                                        Massive scale strategic bombing and nuclear weapons are not substitutable from a military strategy standpoint and everyone would have understood the implications of that. Any similarity is superficial.

                                                        The massive bombing of Japan was a grinding war of attrition that has well-understood limitations and challenges. Military leaders in Japan were perfectly capable of understanding what those campaigns couldn't do, so it came down to a willingness to accept the losses to maintain strategic optionality, which they clearly were.

                                                        Most of the limitations of strategic bombing campaigns do not apply to nuclear weapons, which is something the Japanese military leadership also understood, though the scope of capability was uncertain (which also probably helped). If the US switched to nuclear weapons instead of conventional bombing campaigns, which was the risk Japanese military leaders had to consider, it takes most of the strategic optionality off the table at which point there is little to gain by continuing.

                                                          I think there was also the shock effect of this one tiny bomb with that much power. And the Japanese didn't know that America only had those two available. They could have had thousands for all they knew.

                                                          And this is also something that could strike their leadership. You can build bunkers against conventional bombs but for nuclear that's a different ball game

                                                            My understanding is that Japan had agreed to surrender under the conditions that they got to keep their emperor, but the US had rejected that looking for an unconditional surrender*. A lot of the research around that time indicates the drivers for dropping the nukes included both sending a message to the Soviets and the overall cost of the Manhattan project (and an unwillingness to let the war end without “recouping” some of that cost). Whether the Japanese surrendered when they did or surrendered a couple months later, though, Japanese surrender was largely expected at that point.

                                                            One can argue about the increased cost in terms of lives if the bombs weren’t used, but my understanding is that by that time, we’re talking about shortening the war by maybe months, but certainly not years.

                                                            (*Worth noting that in the final terms, the Japanese did keep their emperor, but the US was demanding an unconditional surrender as a matter of principle.)

In actuality, both the US and Japan were planning for a long campaign on the Japanese home islands: https://en.wikipedia.org/wiki/Operation_Downfall. The Japanese intended to prolong fighting as much as possible to force the US to abandon the invasion because of mounting costs and casualties.

                                                              Even the night before the surrender, some among the Japanese military attempted a coup to prevent it and continue the war: https://en.wikipedia.org/wiki/Ky%C5%ABj%C5%8D_incident

                                                                Before that The Japanese had started to talk about a cease-fire, but that cease-fire was expected to include ongoing control of China, Korea, and some of the islands they had taken in the war. In other words it wasn’t a surrender, but rather a let us keep these last little bit bits and maybe we won’t kill you. It was delusional to the extreme.

                                                                The debate in Washington at this point not if Japan would be invaded or not or would surrender.

                                                                Operations downfall and Olympus were planned. They were projecting anywhere from hundreds of thousands to 1 million casualties on the US side. No one bothered to do the calculation on the Japanese side, but the Japanese leadership believed that their path of victory was to make it prohibitively expensive in American lives to take the islands and they didn’t care how many Japanese died. You can take a look at the ratios of Japanese dead to American dead on Iwo Jima, the Philippines to get an idea of the bloodbath that that would’ve been.

                                                                Of course, some Americans were seeing that the Japanese were far stronger on the islands and they anticipated. And we’re pushing for a total naval blockade instead. Japan’s economy and agricultural harvest had already collapsed. A total net naval blockade would’ve killed millions.

                                                              This is false. There has never been any historical record at that time that shows that “warning the soviets” was any part of it. In fact, the USA disclosed the bomb to stalin beforehand hand. Anyone who postulated that was not in the chain of command. The Americans still very much believed at this point that the best post wore outcome was an ongoing alliance between the United States and the USSR. It was only after the scale of Stalin‘s ambitions in Eastern Europe became apparent and the aftermath of the Nuremberg trials that it was becoming obvious that there would be an ongoing confrontation.

                                                              I strongly suggest the recent book on operation downfall, as well as the recent popular works on the last months of the war from the Japanese point of view.

They occurred at the one moment in 20th century where their power could be seen in a way that everybody immediately grasp the outcome of it and that no response was physically possible. They also occurred at the one moment in time in which a multipolar world essentially coalesced to a bipolar world.

Merely testing such a bomb on Earth would have been an act of mass destruction.

                                                                          […]

It's amazing what goes inyo "just" hitting a static target from a static position at 25 yards with soft time constraints. It's amazing what goes into hitting a moving target from a moving plane in a few seconds.

                                                                                • yread 9 hours ago

Crippling industry instead of punishing civilians.

                                                                                      They eventually lost out to the former, culminating in horrific napalm raids on Japan that continued even after the atomic bombs were dropped and had more casualties

                                                                                        The "bomber mafia" (they didn't call themselves this) were prewar strategists who thought you could destroy an enemy's ability to fight by hitting his strategic and tactical assets with bombers.

                                                                                        Basically they thought that bombers would be to the next war what artillery was in WWI.

                                                                                        What ended up happening is level bombing wasn't very precise, it was often hard to identify the correct targets, and modern mechanized war machines were more resilient than expected so bombers ended up not being as decisive as expected.

                                                                                        "Area bombing" or "carpet bombing" and the strategy to "dehouse and demoralize the population" were tactics developed during the war when the earlier tactics weren't working.

                                                                                        • jleyank 12 hours ago

                                                                                          • seabass-labrax 9 hours ago

The USA joined in the thick of WWII when the Germans/Axis were doing considerably better. A prevailing (but ahistorical) view among Germans after WWI was that they had surrendered prematurely in 1918, so that might have also led to a cultural disdain towards surrender.

                                                                                        • thunderbird120 12 hours ago

To put a bomb precisely on target back then you needed something like a dive bomber, a tactic which is incompatible with strategic-scale bombing. Even "precise" methods using advanced analog computers like the Norden bombsight could only do so much.

                                                                                          >Under combat conditions the Norden did not achieve its expected precision, yielding an average CEP in 1943 of 1,200 feet (370 m)[1]

                                                                                          This means that 50% of bombs fell within 1,200 feet of the target, which is an absolutely awful accuracy if you're trying to hit anything specific.

                                                                                          This was further compounded during the campaign against Japan by the heavy reliance of Japanese wartime industry on cottage industries which were dispersed almost randomly within Japanese population centers, rather than being located within specialized industrial districts. From a purely strategic standpoint which is only concerned with destroying the enemy's ability to make war, the most effect way to disrupt these kinds of industry with 1945 technology was essentially to burn every building in the city to the ground. Other options were simply ineffective.

But the systems fatally depended on accurate radio reception, and the British invented the first electronic warfare techniques to successfully counter this weapon in the 'Battle of the Beams' "

                                                                                              I do hope wherever you are from that your cities are larger than a few hundred yards.

The USA would have required at least an island near the Japanese mainland on which to establish such a ground station, or perhaps a ship if it could maintain an accurate position based on traditional methods.

                                                                                                Even then, I don't think it would be correct to say that the Americans had no other capabilities for targeted attacks. With air superiority you can do strafing at relatively low risk, which is very accurate. And the USA had also developed rockets by this point, which could drastically improve accuracy when compared to unpropelled bombs. They even used these operationally against Japan before the atomic bomb attacks.

                                                                                              • nopelynopington 14 hours ago

                                                                                                It was nowhere near as precise as today's tech but it vastly improved during the course of the war.

                                                                                                Ultimately it didn't work because the theory didn't work. German manufacturing was not disrupted by precision bombing enough to matter

                                                                                                Masters of the air also touches on this, and some of the disastrous missteps during the raids that led to aircraft loss

                                                                                                  Level bombing with dumb bombs was never going to be particularly precise regardless the sophistication of the bombsite because bombs in free fall don't have the momentum of an artillery shell so their trajectory is less dependable.

                                                                                                  The norden also had a multitude of parameters that the bombardier had to input quickly and accurately as they were changing during a bombing run under flak barrage.

                                                                                                  That being said the real problem with the air war in Germany was target selection. If you want to know more I'd suggest the book The Collapse of the German War Economy

                                                                                                  During the bombing of Dresden bombs somehow gravitated towards the city center 2km in diameter, while factories and railway hubs on the outskirts weren't damaged at all.

No B-29 in those first batches weighed exactly the same, a worrying state for such a highly complicated aircraft. Only 20% of the "finished" aircraft could be flown out of the factory. Badly fitted windows and observation panels bled air or were distorted, and many electrical plugs in the plane's 16km (10 miles) of wiring didn't work properly.

                                                                                                        Any European today still wonders why Tesla workers in the US still cannot hold a screwdriver, producing widely worrying results and claiming that the product is a valid car.

                                                                                                          The British Overseas Airways Corporation (BOAC) were desperate for new aircraft after the war. They would have bought Lockheed Constellations if they hadn't been pressured into rescuing the British aircraft manufacturing companies from financial obliteration, which had of course narrowly avoided direct obliteration from German bombing. Instead of buying new American aircraft, they converted British bombers like the Avro Lancaster into sub-par airliners and eventually brought the Bristol Britannia into service, which was a fine aircraft, just ten years too late.

                                                                                                          The de Havilland Comet eventually made BOAC and British engineering competitive internationally again, but I think it would be improper to not give credit to American workers and designers for being the first to create such advanced aircraft as the Constellation which really did keep the Allied war effort going behind the scenes.

                                                                                                          As for the Germans, they had rockets and all kinds of incredible experimental aircraft, but nothing quite like the USA when it came to high-altitude air freight.

Parts were magnesium to save weight, which could get rather excited if some parts broke and the fire started. A small time to bail out before the wing root burned through.

I've driven from Tallinn to Kyiv five times over the last year, and I've seen plenty of American vehicles. I know in Ukraine it's popular to kit bash imported wrecked US cars into something drivable, and I've seen plenty of full-size Dodge and Ford pickups on the roads in Poland.

                                                                                                                                  On 13 June 2025, I took a picture of a Honda with dealership plate frame from Bellevue Honda in Tallinn. I imagine many of the vehicles in Holland and Germany are owned by US military folks, but they can't all be.

Ford was really big here at one point but it's a shadow of what it used to be. Tesla was an exception until Elon decided to go full-on Nazi-wannabe.

                                                                                                                                          And it doesn't look like it will recover again:

                                                                                                                                          Other than that there are some people that have legitimate needs hard to cover with EU made vehicles, for instance larger pickups. Those are often imports, Toyota's, some Dodges, some GMs. Rarely Fords though, I don't remember when I last saw an F150 or an F250 here in NL, in Germany or Poland. The Dodge's are popular with landscaping crews here.

                                                                                                                                          In '24 Tesla did very well here (NL), with close to 8% of the market. For '25 they'll be happy to have half of that. And I expect BYD to achieve parity or even to exceed Tesla for EVs. Ford is at 3.5% and Jeep at 0.5%. So in total, for NL including Tesla the USA represents about 12% of the market and next year more than likely less than 10% and if Trump keeps up his tariff bs it might be far lower than that.

Similarly GM (AKA Vauxhall/Opel, now Stellantis) pushed the Corsa/Astra and so on rather than, say, the Chevy Suburban.

                                                                                                                                            A majority of them are made within Europe (if not necessarily the EU, between the UK and Turkey) so should avoid tariffs.

They're hard to park here (parking bays are smaller), difficult to drive in narrow historical cities, expensive to fuel etc. And pick-ups are very unpopular here, unless you're a farmer there's no point in such a large open loading bed.

                                                                                                                                              I remember choosing between a Nissan 100NX and a Ford Probe (both about 10 years old) but the latter had way worse fuel economy not being a Europe native model (though it wasn't really a US model either I think). Also the 100NX wasn't really a sports car, it was just a Nissan Sunny compact with a more sporty looking body and T-top. It was a super nice car though.

If you see something pick-up-like, it's usually more a variant of UniMog https://en.wikipedia.org/wiki/Unimog .

                                                                                                                                                And for the "small-time farmer without enough money to buy lots of equipment" (rare nowadays), tractors with tons of included functions were often more practical: https://de.wikipedia.org/wiki/Fendt_GT (no english version, sorry). Since Germany is more dense and distances are smaller, low speed is less of an issue I guess, compared to the US. And you can pull real farm equipment, which a pick-up car usually cannot.

                                                                                                                                                  Yeah it's also that American pick-ups usually don't feature 4WD (unless as an even more expensive option) which is kinda a need if you're into farming. It's a weird niche for people that want to show they are outdoorsy somehow but aren't really.

                                                                                                                                                  And for people that just need to move a lot, having it exposed to the open air is usually a dealbreaker. Panelvans are much more popular for that. Or MPVs with removable seats.

                                                                                                                                                  I have seen other countries where they are popular though. Like in Australia where they call it a "Ute". But yes also a long-distance country like you say.

                                                                                                                                                  The Ford cars sold in Europe are mostly European-designed and European-built though, seeing an actual US Ford model on the road is quite rare (in Germany at least). And the Ford factory in Koeln is so old (founded in 1925) that I'd say it's not unusual to recognize Ford as a German brand over here.

                                                                                                                                                  • Rover222 11 hours ago

Being against mass immigration? His support for the German AFD party? That’s the 2nd most popular party, hardly a fringe extremist Nazi party, despite its distant roots. Far left people are lately the most anti semitic, so it’s all ironic.

                                                                                                                                                    If you think he really did a Nazi salute, you’ve just drank the media kool aide.

                                                                                                                                                      But ultimately the Nazis were a specific brand of fascism. You don't need a Hugo Boss uniform and a lower limb disorder to be a fascist.

                                                                                                                                                      You do need to be actively opposed to fair elections and other bedrock progressive values, a cynical exploiter and promoter of race hatred and violence for political ends, and a dedicated corporatist.

It doesn't look scary at all, yet that silhouette must have been as terrifying in its prime as the B-2 is now.

                                                                                                                                                            B-29 service ceiling was 9710 m.

                                                                                                                                                            https://en.wikipedia.org/wiki/Messerschmitt_Me_262#Specifica...

But it's also completely crazy to think that as soon as it was in service the Me-262 had made it obsolete. Also the German development of guided surface to air missiles. The US immediately had to build a pressurized jet bomber that would operate in a considerably tougher environment.

                                                                                                                                                            The US had began working on what would wind up as the B-52 that would fly 6 years later in 1951.

                                                                                                                                                            By that point you'd think that everything would keep changing.

                                                                                                                                                            Yet here we are almost 75 years later and the B-52 is still a US combat aircraft that is expected to stay in service until the 2050s.

                                                                                                                                                              Yes, but the B-52H still in use are very different from the ones built in 1951.

                                                                                                                                                              Yes, but the youngest B-52H was built in 1962.

                                                                                                                                                              So much closer to the days of the Wright Flyer than to the present day.

                                                                                                                                                              • UncleSlacky 14 hours ago

                                                                                                                                                                                    I understand that the manufacturing and testing was a nightmare, with the need to redesign multiple subsystems.

The absolute cheapest 4th generation fighter would cost you an order of 20-30 million dollars to import brand-new, whereas 4.5th generation platforms like the Rafale commonly fetch 100m+ a unit to import.

                                                                                                                                                                                      As far as credible 5th generation strike fighters go, that's a pretty cheap per-squadron price tag. My bigger gripe is with the "Big Bomb Diplomacy" tactics that require such a platform, but we'd end up wanting one either way if a fight with China is in the cards.

Of 40,000 kriegsmariners trained for u-boats during the war, 75% became casualties. Incredibly, this was even higher than Kamikaze squadrons (on account of the fact that not all flyers were assigned a mission, and not all missions ended up finding a target)

In conventional attacks whole groups of planes flew right into the teeth of US air defense, fighting threw 3 layers of death and getting annihilated.

                                                                                                                                                                                        The reason they adopted Kamikaze was that normal air-attacks were suicide but suicide with no results what so ever.

                                                                                                                                                                                        In Kamikaze the pilots had more freedom and often only attacked the outlining ships. And quite often they just bailed out, or faked engine problems and flew back.

                                                                                                                                                                                        In terms of the 'strategic' bombing in Europe, the US was just incredibly arrogant and didn't want to listen to the Brits who had already learned some lessons. The way they employed air-power was outright insane, suicidal and also completely and utterly ineffective.

                                                                                                                                                                                        It took smart people using internal politics to sideline the idiots to turn the strategy around and do something actually useful.

This appears to have been on all sides. Maybe the Americans were better, but that just may be because they didn’t have time to get bogged down. I heard that Pershing refused to follow British and French tactics.

                                                                                                                                                                                            I assume that this was because many generals were trained on Napoleonic-Era tactics, that didn’t do well, against machine guns and semiauto rifles.

It demonstrated the power of the defence over the offence, and the sheer magnitude of war that an industrialized nation could create. Most people figured WW I would have ended by Christmas. Oops.

Prussia was able to use field artillery effectively to support infantry attacks. The overall scale of fighting was similar to the US Civil War, but the war was much shorter and the individual battles larger.

                                                                                                                                                                                                  If there was a war European WWI leaders had ignored, it was the Russo-Japanese War of 1904-1905. By then, technology had advanced enough that the teachings of the Franco-Prussian War were no longer valid, and defense was again stronger than offense.

                                                                                                                                                                                                  • InTheArena a day ago

It’s mind-boggling. I’ve always thought that it was crazy how much of a straight line there was between the trenches around Richmond and the trenches of World War II.

                                                                                                                                                                                                    • arduanika a day ago

                                                                                                                                                                                                      There's a theory that Longstreet saw it all coming, too, but was unable to get the point through to Lee. That is, he saw that trench warfare was going to be the future.

                                                                                                                                                                                                      But yeah. The European general staffs were modeling all their train timetables on the fast Franco-Prussian War of 1870.

                                                                                                                                                                                                        Grant saw that you have to kill everyone or kill their ability to kill, or both. Lee was looking for the illusive decisive victory to create a political end to the war.

                                                                                                                                                                                                        In fairness, the Confederates had an incentive to not see this, as an agrarian slave state cannot out produce a nascent industrial state.

                                                                                                                                                                                                    Everyone was trying to solve the problem of trying to figure out how to fight, and no one could keep up with how fast warfare was changing. Armchair generals watching people die in almost real time from drone footage in Europe did not exist in 1915.

                                                                                                                                                                                                        The reason we have this view of WW1 is that after WW1 in the 20s many normal people in the 20s started writing about the horrors of war and that combined with the strong anti-war sentiment lead to the view we have now. Claiming that generals like Haig was an incompetent butcher. The whole 'lions led by donkeys' myth.

                                                                                                                                                                                                        However non of that is actually true. Or not anymore true then in any other war. For example, there is stark contrast to right after the war, where Haig was considered a hero and most soldiers in their post-WW1 writing liked him.

                                                                                                                                                                                                        In terms of causality rates, WW1 isn't that special, high intensity combat in modern war isn't that different, from Crimea to WW2. If you have warfare at that level, even if you are successful, you have massive causalities. The Somme for example wasn't that different from the Normandy campaign in WW2.

How do you command 500 men in a coordinated attack without communication?

                                                                                                                                                                                                        The Americans had to go threw the same learning curve as the others, but they started right away fighting against an enemy that was mostly veterans. Americans could have learned better, but it also has to be said that Pershing by command from the president was not allowed to fully integrate his troupes with that of the French army.

Semiauto rifles practically didn't exist in the beginning of WW1. And machine guns had existed for a while and were not that effective.

                                                                                                                                                                                                        The big killer on the battle field is the fast shooting artillery. Massive innovations in that had happened in the 30 years before WW1.

                                                                                                                                                                                                          The fact that the war was effectively stalemate for 2ish years also contributed to both the medical issues involved and the psychological impact of combat too.

                                                                                                                                                                                                          They did have fairly strong and comprehensive landline field phone networks, wireless wasn't really needed.

They didn’t understand and didn’t learn the lessons of the us civil war that the capability of production made defeat of the enemy in the field impossible. French strategy was attack, period.

                                                                                                                                                                                                              They didn’t contemplate the impact of the lines moving out to 1000 yards, machine guns at the company or platoon level and the idea of the entire state as the enemy. Germany ultimately collapsed because their society was sucked dry.

                                                                                                                                                                                                              Calling critiques of a conflict that slaughtered 20 million as propaganda is probably one of the more ridiculous statements I’ve read in awhile.

IIRC he then volunteered to help with the Nuremberg prosecutions.
