How would the crew of A turret have fired off the famous last salvo, i would have thought the whole gun crew would have been thrown to side of the turret or been slid down to the side of the turret?

[@kurumi394]

It seems like every other major naval power took gradual steps in designing battleships after the Naval treaties; i.e. GB built the KGV class and Nelson class before moving onto the Lion class, and the US built the NC, SD, and Iowa classes. With Japan, who withdrew from the treaties in the 1930s, why was there such a massive jump? Why did they not design any new treaty compliant battleships after the 8-8 plan was scrapped and just went straight for the A-140/150s?

35:20 Plus, after steaming 48 more hours at high speed she'd be a bit lighter, and as she was starting a turn to port, the moment of her rudder's initial movement would likely have listed her to port ~ 5 degrees as the helm was applied, thus exposing that area even more. Excellent argument! Lest we forget.

[@coffey3c]

Very interesting, and seemingly Very likely. Of course, as my years have gone by, I've grown more and more uncomfortable with the suggestion that the men of the hood somehow contributed to their own demise. A confluence of circumstance due to maneuver, along with the fine gunnery of the kreigsmarine sailors, seems more meet as well as likely.

[@English-Hound]

Something my father told me was, when he was first aboard the ship he was taken round the ship with a petty officer. They went into a room that had a lot of cannon balls, my father asked "What are those for surely we don't fire those?" the reply was "When we get into action you'll soon find out." Well later they did get into action during the Bismarck hunt and the turret my father was in was actually hit by a shell that passed behind him. The velocity from the shell burnt the seat of his pants out, one of the chaps next to him was not so lucky as he was decapitated. Later the use of the cannon balls became clear, as they were put into the canvas bags at the dead sailor's feet for burial at sea.

[@kevinbendall9119]

When I was serving in the U.S. Reserves after my active duty tour, I worked with a very good Senior Chief who was a nuclear engineer. In civilian life, he worked for a company that had a contract to design the ammunition hoists for the U.S.S. Theodore Roosevelt. A major consideration of the design was to prevent the bypassing of the safeties so blast doors could be open simultaneously. Million were spent "sailor proofing" the lift system. He told me that on the first acceptance sea trials, it took the crew forty minutes to defeat the interlocks and open all of the blast doors at the same time. So much for that theory...

Funny story about that. One of my friends is an officer with the USMC. His unit was tapped to field test a new... Widget by The People Doing R&D. The researcher in questions handed him a few of this widget and basically said, "we've designed this to be grunt proof. I'm heading out of country tomorrow, send me an after action report if any of your guys manage to break this." Three hours later my friend was standing in front of this R&D guy with a hundred pieces of widget. When asked how the hell his Marines had managed to break it, he responded, "They put it in a freezer and then shoved it between the road wheels and track of an Abrams." "Why the hell did they do that?!" "I thought you said it was grunt proof?"

The thing is you say defeated the system, did they intentionally defeat it? If there were doing everything they could to bypassing it then the system was reasonably good as having that many steps to achieve a unsafe condition should not happen in a real world situation. If it took 40 minutes accidentally then the system was junk as a series of events to achieve this were not alerted to.

[@kevinbendall9119]

@@NavyVet4955 It took that time the first time. Because the transport time is long, crews were notorious for bypassing the safeties to get weapons on deck for faster turnaround of strikes. The system was supposed to prevent it, but it is still wiring, and any system can be negated. I don't know if it alarmed, I wasn't there, but the whole point was that the doors are opened when the ship is most vulnerable, during active operations. Ask the British what can happen...

Its interesting to note that, although Prince of Wales retreated behind a smoke screen after the Hood was sunk, she got 2 crucial hits on the Bismark, 1 straight though her bow causing a large amount of flooding and a reduction in Bismark's speed, and another one in one of Bismarks fuel tanks causing a loss of critical fuel and also causing a trail to be formed behind Bismark that made her easier to spot by ally planes.

Yet, for all their practice drills, rarely did the RN produce a really remarkable display of gunnery with the possible exception of Matapan.

RIP and respect to all those who died.

[@thanatosstorm]

More than half the crew (all in the aft end) would have been gone in seconds. Those in the forward turrets and forward half of the hull wouldn't have had time to evacuate with all doors secured for combat operations. As for the forward bridge, odds are they likely wouldn't have known what the hell was going on.

[@justforever96]

What is so confusing? The ship exploded and was torn in half and sank in less than a minute. There are really survivors of sudden sinkings. 97% of the crew are in the hull or in compartments in the superstructure. Almost all of these have no natural light source or direct escape route. The first thing that happens with a catastrophic damage event is that the entire power grid is severed and the whole ship goes black inside. Then you have to locate your flashlights and try to find your way around the darkness. But with the catastrophic destruction the ship immediately starts to sink rapidly. Those near the damage site who weren't killed by the blast and flash are quickly drowned as the water rushes into the blackened hull. The hull immediately slants steeply and/or rolls and capsizes. Your have seconds before you are trying to walk on a steep roof. While following a maze, in the dark, while climbing up ladders (which aren't even ladders but steep stairs, making it even harder if it is now tipping towards you or sideways). This is assuming you didn't wait for the order releasing you from your post, which will never come due to the loss of the network grid and power. It is extremely difficult to escape from a sinking ships hull once it exceeds a few degrees off level, and the Hood was quickly going bow and stem towards the sky. Almost no one still alive had any chance of escaping the hull, the deeper in you were posted the harder it was. Not much better in the superstructure or turrets, unless you happened to be right by a door (all the doors and hatches to the outside and between compartments were shut and dogged when you went to quarters so you have to stop and open every one of those too, don't forget), and you basically sprinted for the exit the moment you felt a bad explosion assuming the ship was doomed and your life was more important than potentially being charged with deserting your post of our turned out that it wasn't as bad as you feared it was and the ship didn't sink. Or if you were posted on deck as an AA gunner or lookout. But then you would have to jump pretty quick before the bow raised too high for you to jump, and you would have to swim pretty fast to escape the massive suction of the fast sinking ship. Almost every ship that blew up had no survivors, and it has happened many times. Any ship that sinks rapidly.

One piece of evidence that you don't discuss here, but is mentioned in your Operation Rheinuburg video, is Ted Briggs' account of the impact. He mentions a slow, 10 degree list to starboard (as well as loss of steering... but I don't have any knowledge of how that might fit in). This is consistent with a hull breach at or below the waterline, as you describe, and almost entirely rules out the plunging fire hypothesis or anything associated with the fire on the boat deck.

[@hatchcrazy]

The key to this mystery is, I think, the silent flaming jet that appeared just before the explosion. An erupting, coherent column of flame emerging with no associated shockwave implies a significant volume of superheated gas at very high pressure suddenly getting a narrow aperture to vent through. Superheated gas being present inclines me to believe the 4" magazine did cook off first, as the 15" wouldn't have messed around overpressurizing compartments but cut straight to shattering the ship. The eyewitness accounts also mention the eerie lack of a shockwave/sound when Hood exploded, again suggesting the ship ruptured from internal pressure rather than being pulverized by a blast wave. Hood's destruction sounds (literally) more like a deflagration than a detonation. The ship probably filled up like a fiery balloon in the milliseconds before explosion. In fact perhaps her deck armor worked _against_ her here by holding long enough to let obscene levels of pressure build in lower compartments. Taking all that into account, is it necessary for a shell to have hit Hood's magazines at all? All that's really needed is a way to start a fire in that 4" magazine. Could excessive heat and/or pressure from a near-miss have ignited stored charges in a (relatively) slower-burning deflagration?

[@stevenjermy1098]

Well done Drachs, its a superb analysis; been reflecting on this off and on for years, and this is the best explanation I've seen. Three additional nuanced thoughts. First, the weather on the day, from the footage of Bismark firing, was about Sea State 4 or so, by eye. With Hood steaming at 28 knots, the depth of the exposed area under the main mast will change slightly as she runs through the swells and troughts, with the possibility again of further exposure of the hull area below the main belt, thus potentially further increasing the probability of penetration. Second, if her turn to port is underway, then at 28 knots she will start to list to starboard, by 5 to 7 degrees, I'd guess, which will change the impact geometry slightly, and in two ways: the exposure of the hull below the waterline will be reduced, thus reducing the probability of below belt penetration; but this will be balanced again slightly the change in horizontal geometry, as the angle of penetration becomes closer to perpendicular. Third, and very subtly, if the Hood's rudder has just been put over, but she has not started to turn, then else will come into play. Battleships and battlecruisers were designed with metacentric height such that they were not too 'stiff', and were thus good gun platforms. For any warship, but especially a warship that is so designed, when the rudder is put over, the first thing that happens is counter-intuitive, namely the vessel will list in the direction that the rudder is put over. The reason is to do with the physics, in that the rudder is below the vessels centre of gravity and, at the moment of the rudder being put over, a vertical lever force is applied below the centre of gravity, causing the vessel to list in the direction of the turn. Once the rudder bites, and the vessel's turn commences, then classical hydrodymanic forces come into play, and the vessel will then list in the opposite direction of the turn. In Hood's case, if the moment of impact coincided with the application of the rudder, but before it had begun to bite, then she would have been listing slightly to port, which would have further exposed the hull below the armour belt, and made for a slightly higher probability of penetration as you propose. All of which tends to increase the probability that your explanation is the right one.

[@Damorann]

Amazing video. I remember watching a documentary that stated that the commander knew of his thinner deck armor and tried to close the gap to avoid plunging fire. Considering this very plausible explanation, it makes it even more sad that this kind of incredible hit took place. It draws even more importance to a simple fact about battleships : if one lucky strike can cripple a ship this size, that takes so long to build and so many men to run, why would you ever risk using them ? I always feel that early WW2 should have sounded huge alarms in naval commanders : Taranto, Hood, Bismarck, only to name those before Pearl Harbor, repeatedly show the inherent dangers of huge battleship battles. The tide could turn in an instant, regardless of how skilled and capable your people were, and you just couldn't replace the losses. Those poor souls on the Hood and later Bismarck were betrayed by a lucky shot. Wonderful video.

[@atpyro7920]

The problem with this line of thinking is that the examples listed aren’t really indicative of battleships as a whole. Yes, in our 20/20 hindsight, we understand that battleships as we know them are outmoded, but at the time, aircraft carriers were very much an unproven concept and big gun duels were still thought to be the end all be all of major naval engagements. As for the examples in particular, you run into the same problem with Taranto and Pearl Harbor: both were surprise attacks on an enemy fleet at anchor. While this is something that battleships cannot physically do without some sort of super gun due to their speed, this does not also inherently rule out battleships as being defenseless- if the crews were not in a relaxed state, then it’s very likely that less casualties, both man and ship, would have been inflicted in both instances. As for Hood and Bismarck, again, the same error is evident in both in that both were doomed by a lucky shot- Hood’s more instantaneous than Bismarck’s, but still. The only reason both are so famous is because of how improbable Denmark Strait and the crippling of Bismarck’s rudder were- battles like North Sea, Sibuyan Sea and Surigao Strait prove that battleships could still take plenty of punishment before going down. To conclude, we know for sure that battleships are obsolete in the age of the fully understood carrier, in the era in question battleships were still a viable unit until combat experience proved otherwise.

An excellent analysis from all angles. Whilst it may have been a “lucky” hit from Bismarck it simply proves that having a shot may actually work sometimes - regardless of the odds. In a similar way - the later torpedo hit on the rudder by the Swordfish attack - which led to the demise of Bismarck herself - is equally a “lucky” shot. For good or bad it shows that taking your best shot sometimes works to advantage. In the end it was a one for one swap of battleships and many good souls perished . RIP to all.

A one-for-one numerically maybe, though in chess and warfare, like-for-like swaps are rarely fair exchange.

No doubt the Admiralty had to risk the Old Girl. Like in the Battle of Britain, maybe straight swaps are not a "thing" when you have the enemy outnumbered, or when the enemy asset carries a greater threat.

One point you should note: The water in the through of the wave would have been agitated. Agitated water offers significantly less drag and has no surface tension.

The expedition to Hood's wreck (her rudder positions) showed that Hood was in the process of turning to port when the shell hit. Now, beside the through of the wave, the fact that she was turning, and heeling over to port at 28 knots (albeit at a shallow angle to port) may have exposed a few extra feet of her hull.

@@RayCis1 I think you are mistaken there. She was hit on the starboard side, any boat with a rudder (that includes almost all ships) will heel out when turning. So if she was turning to port Hood would have listed to starboard and therefore "hidden" part of her hull. With that said, when turning sharply, both the bow wave and wake will change form and structure. It might have exposed more of the hull in the area she was hit.

By coincidence, I was going through the Nathan Okun resource on Navweaps, and I was reading through his analysis of the HMS Hood and the results of the 1919 armor tests, made against various permutations of her armor (the end result of the tests was a thickening of her deck armor). The title is a little misleading though, because Okun also goes into possible causes of the loss of the Hood, and there's a lot to chew on there! His analysis partly mirrors yours, in that he agrees that an aft engine room hit would likely set off the aft magazines. Okun also discounts the possibility of the shell punching through the 7" upper belt and then the 3" armored deck (this is his Scenario #1); it'd skip right off the 3" deck and cause some havoc high in the ship, but not in the citadel spaces. So far, so good. However...by his calculations, at about 9.8 degrees angle of fall, a 15" shell that hit the 7" plate over the aft engine spaces would penetrate and then *only have to contend with a 2" deck*, since according to Okun, the armor deck had been thinned here. And this was something the 15" could penetrate at that angle of fall, even after being slowed down by the 7" belt, ending up right in the aft engine spaces (where your scenario also had the shell fetching up). After that, things go very similarly. This is his Scenario #4. I guess the key question for his analysis is if the armor deck thinness for the aft engine spaces are right or not. Okun's armor-penetrating formulae are downright exhaustive and extensively cross-checked against historical test results, so they're very reliable. Both his scenario and yours are very convincing, and the video does an excellent job of presenting the case. Either way, it was an extremely unlucky hit for the Hood.

Pictures of Hood are shown with the quarterdeck completely awash at speed or in heavy seas. After the war when Bismarck's specifications were studied, it was found that Hood had no immune zone to Bismarck. In the absence of lucky hits, the Hood was doomed in this scenario.

That was a fascinating and very plausible explanation. The arguments and rebuttals against the other theories made perfect sense. Thank you, drach

A remarkably detailed and rationalized presentation, well-presented as always. You were kind enough to acknowledge William ("Bill") Jurens as providing substantially to your presentation. Reading through the well-deserved accolades in the comments, I was struck by the remarkable lack of your followers mentioning the contribution, which you appropriately gave to Mr. Jurens. My little thanks to him as well is intended to make up - minutely - for this general omission. (It would also be interesting to see if the British Admiralty would commenton, or even acknowledge your presentation.)

This is by far the most detailed video I’ve ever seen, I went into this thinking “eh why not listen to another video about the HMS Hoods demise” but you had my full attention by the end.

[@costalepas7192]

My thoughts go out to all the brave men lost with the Hood. They were remarkable heroes who fought to the bitter end. Rest in peace lads!!!

Never forget her Aft turret was still firing as it sunk beneath the waves

[@danielbtwd]

I remember listening to another documentary about this episode. There was an account of the response of the sinking of the Bismarck by the house of parliament which was a roar of cheering. The accounts of the people on the ground was very sombre. No sailor likes to see a ship go down even when they are the enemy.

[@torenico]

It's insane to think that this explosion lasted for mere moments. Poor sailors nearby didn't even noticed, no wonder only 3 guys survived.

[@seawolf4846]

IIRC, they were all up in the fighting top.

[@davidwong825]

The facts that they got far enough from the sinking ship always troubling me, NO disrespect

[@adamtruong1759]

I always wondered/had trouble wrapping my head why around when the magazine of a ship detonates, almost all the crew die. Sure it's a fairly large explosion, but aren't their many other places some of the crew could survive?

[@alexeisinitsa]

@@adamtruong1759 and what next? To stay alive, they need to a) get an order to "abandon ship" -- otherwise they are defecting, and deserve a quick court-martial, and gallows in wartime; b) be able to execute said order: good luck with that, if you are anywhere but on the upper decks or otherwise outside of the structure -- and there are precious few who are lucky/unlucky enough to have their station outside, in a live battle (and as the ship sinks, all matter of things go wrong: the gravity is battling you -- decks become sloped/vertical instead of horizontal, damages jam hatches, etc.) c) have fate on your side to actually stay afloat and survive. As the ship goes down, it releases a bunch of air -- which means you are in a bubble bath, water density is way below 1 -- even a life vest might not keep you afloat for a while; you may well drown in the meantime. Then, all matter of wood starts floating up from the wreck, and if it gathers enough speed, it may hit you bad. Oil on the surface is bad, even if it doesn't catch fire. Hypothermia is a murderer, too. The question is rather "how lucky are those few that actually made it"...

[@rafaellopez2765]

What a great post...!!!! Thank you for your work and keep alive the passion for history.....

[@DaystromDataConcepts]

Thank you for this fascinating and highly detailed analysis.

[@johnsmith-iv8ul]

My grandfather was assign to this ship, but few days before my grandfather was to go out on that mission where those poor souls where lost. He caught a disease and had to be quartined in hopstial so he was replaced. I know this story sounds silly but it is true. And when I think about it I wouldn't be alive now if he didn't get infected. This is the story my father told me.

[@jackthorton10]

Fate has a funny way of saving a life… but also taking one

[@johnsmith-iv8ul]

@@jackthorton10 your not wrong about that 👍

[@Matt-yg8ub]

I have a similar story about my Grandfather in the 10th mountain in WWII ending up in the infirmary, missing a deployment and surviving the loss of the whole unit.

[@MrSGL21]

this theory makes the most amount of sense. when he started talking about below water line hits and you see the picture of the ship you realize that yes thats likely what occurred. Drach failed to point out something about the bow wave. as the ship is turning, the bow wave on the side in which they were hit is being pushed farther out from the hull as the ship swings through its turn. the ship is throwing water in the opposite direction of its turn while sucking it in on the side in which its turning to. you're going to expose more hull on the side that is in the outside of the turn, the side that took the hit.

[@adukes2440]

Whilst he may have failed to point out that particular fact, he does state in the video that though the rudder was found locked to port in the wreckage, its more than possible the rudder had yet to overcome the ships inertia by the time it was struck by the incoming shell, and therefore still moving in a rather linear motion.

[@Archangelglenn]

@@adukes2440 Though there is still enough doubt cast, that I think the note does deserve to be well noted.

What a great and enormous amount of information to digest....great great job!!!
