[@themightynanto3158]

I've read from the Damage Report of the USS North Carolina's torpedo hit from I-19, that the torpedo did actually did cause a flash in Turret One's Magazine and that it could have possibly detonated the magazine if it had struck even slightly aft than it did. Is that actually true, and do you think I-19's torpedo could have done that had it struck more aft than it did?

[@bamafan-in-OZ]

Given its highly likely a shell from New Jersey's 16" guns would go straight through a ship of the line, in the unlucky event all she'll miss the canons I wonder how many shells it would take to sink something the size of HMS Victory

One of the close calls I had was when a defective 5" 38 HE round exploded right outside the gun mount during a training exercise. It left a sizeable dent on the frontal armor right where I was stationed. Some of the shrapnel flew back onto the bridge, too. Yes, I have tinnitus.

[@TomFynn]

Makes me wonder: The proximity fuze in WW2 is generally hailed as a game changer. Given the number of rounds fired, how often would the fuze detect "enemy nearby" just after leaving the muzzle? Or worse, while still inside the barrel?

[@Hyssar]

@@TomFynn If I recall correctly, in the WW2 channel Spies & Ties special episode about "Allied superweapons", that the proximity fuses had a delay built into them so that they wouldn't explode too close to the ship by accident. I believe it was the firing of the shell itself that activated the delay. I highly recommend you go check out that video!

[@TomFynn]

@@Hyssar If as the OP told, the round detonated right after leaving the barrel, I think we can assume that the fuze was faulty. And in WW2, given the sheer number of rounds, there must have been defective prox fuzes, which went boom where they were not supposed to simply because the delay was faulty or wrongly installed or any number of things. So the question is, how often did such a fuze suffer from premature detonation?

Perhaps a little unrelated, but the glass marble example mentioned, triggered an old funny memory from school. The school I attended has four floors, and in one location there are stairs with an open volume through all floors down to the basement floor. Thus five floors. The floor at the bottom is smooth stoned slabs, very tuff and hard. So... one day walking the stairs, holding a small billiard ball that I inexplicably had found somewhere, an intrusive thought raised it's stupid head. I could not resist, so from the top of the stairs, looking down an estimated 18 m(?), I threw the billiard ball, balancing force with control, as hard as I could down towards the bottom of the stairs. I expected the ball to shatter, but to my surprise, the ball bounced back high enough for my friend standing one floor below me to catch it. Examining the ball, there was little to see, just a small mark of contact. Looking at the stone floor... there was a somewhat larger mark of contact. The slab was cracked to each corner, with a very visible crater at the convergance of those cracks, but it had not shattered either. Physics is fun, in theory and practice. We the started to calculate the G-forces involved, but decided to go talk to the girls walking by instead. That is at least how I choose to remember the end of the story... 🙂

[@space_artist_4real138]

As a mechanical structural engineer, this is an excellent explanation for the phenomenon and their effects in shell impacts, shockwave, compression and what their stresses want to do to the shell. Putting down this basis is very good for the explanations with armored caps. Also, the sacrificial role of the AP cap, made to take the worst of stresses of the impact. A sacrificial penetrator made to push the strongest part of the armor out of the way of the shell, and get itself out of the way by shattering. I never thought a shattering object could be used to absorb energy, but I guess what actually happens is this does the inverse, concentrate energy inwards to create damage.

[@kemarisite]

Honestly, the biggest changes are improvements to explosive fillers and fuses so they actually "delay" properly, and greatly increased hardness for the armor piercing cap.

[@denysvlasenko1865]

Most important advances happened during WWII: shaped charges / explosively formed penetrators. They are the reason why today's ships are not heavily armored (they can stop 20mm projectiles at best). You can't realistically have armor thick enough to withstand a EFP formed by a warhead with 15 or more kg of explosives, would need something like 80 cm of steel.

@@denysvlasenko1865 you could but you would have to consider doing it to the scale of Abrams armor. Though actually modern armor piercing weapons are only designed to go through one piece of armor. Like the deck armor on ships back in WW 2 you would be going through at least two layers and they would be ten feet or more apart. THAT is why the comparison to weapons meant to take out a tank fail when talking about armored ships. You are not trying to kill four men in a small compartment.

This is the best video I’ve yet to watch on the topic of modern naval shells, with appropriate pictures accompanied by succinct narratives, Thank you.

[@jonathanrichards593]

Well, it's not exactly *modern*, except by comparison with cannonballs. No modern ships have these enormous calibre guns, and so we're not equipped to fling these monstrous shells, either. Naval guns firing big shells are almost obsolete in the scenario of anti-ship missiles and air attack, although Royal Navy destroyers are still fitted with 4.5 inch (114 mm) Mark 8 guns. What they lack in sheer mass they make up for in great accuracy, and rate of fire, but they're not primary armament.

[@felixcat9318]

An excellent, detailed explanation narrated in a clear, concise manner. Technical enough to be relevant, clear enough to be understood by people without engineering knowledge. The narrator achieved that difficult task of giving a clear, detailed explanation without alienating or boring viewers that don't know enough about the specific subject. The knowledge from this video increases my respect for the men that faced these weapons in war. My father and several uncles served in the Royal Navy and my uncle, whom was a gun layer, revealed absolutely horrific details of what occurred on board during and post engagements. I understood why such information was voluntarily suppressed and never made public. I considered myself extremely fortunate to have been born after the war had ended, what our forces endured for the length of that conflict was something that today's generation would find impossible...

it's not really geometry, at least in the commonly used meaning, the only things you use from it is trigonometry, most of the calculations are algebraic (I can still tell you how to calculate the simplest case involving no air resistance and it's all algebra, the only geometric thing is the firing angle)

After which they were past each other and the range opened up until Washington fired a final salvo at 12,650 yards. That's not exactly "long range" by WW1-2 battleship standards, but it isn't particularly close range either...

[@tendymusic9095]

Unfortunately, I cannot tell the class or type of ship, but being that the rear turrets are super firing That’s a good inclination that the ship is relatively modern at least from the 20th century so my best guess is that it is using smokeless powder and perhaps a black powder ignition charge I don’t know the proper term for it, but the black powder would’ve been used to ignite the smokeless powder so my best guess is that it could be a smokeless powder ship that is just beingshot with a film that was not particularly happy with the shade of smoke that was coming out of the gun

Yes was point blank

[@hitoshisawa8479]

@@JeffEbe-te2xs in other words that says a lot about how better the armor was it was rated too stop 18inch shells

[@trierog8440]

Does anyone know if the shell was fired with a full or reduced charge? I would not be surprised if it was fired at a reduced charge to attempt to mimic a hit from a greater distance.

A beautifully articulated narrative, both knowledgeable AND humble. Your pains to point out the limitations of your essay, and the danger of rushing to sweeping conclusions is a breath of fresh air in a media landscape saturated with spin doctors and polemicists. I would love to know how many armchair hawks got through to the end. And by armchair hawks I mean those who believe firepower is the answer to every problem both in war and ordinary life. The people who green-lit the building of these battleships, believed firepower was everything. Gunship diplomacy ASSUMES firepower is everything. The reality of a shooting war is very different, to this day! It is never as simple as blowing shit up. We see that in Gaza today. Armchair hawks will bluster that levelling the place will teach the enemy a lesson... and it does! Many! Just not the lessons the hawks believe. War is never about killing all the enemy, it is about convincing enough of the enemy that continuing the fight is impossible. And this is hard to do this by firepower alone, in the complex environment of modern industrialised warfare. Simple people demand simple answers and there are no simple answers in the fog of war. The devil is ALWAYS in the detail. And many of those details were set in stone by engineers years before the battle, and that is a very scary thought. The battle of Jutland is a perfect example of just how complex war is, with both sides having reasonable cause to claim victory at the time. In the end winning the war, beats the hell out of winning all the battles.

Yes please do another video of shell impacts.

[@BallisticCoefficient]

A magnificent production. - Thank you so much.

[@stevebarrett9357]

I remember reading (I think it was Geoffrey Bennett's Naval Battles of the First World War) that after Jutland it was determined a number of the British large caliber shells exploded or otherwise broke up on impact instead of penetrating. I recently read an article which suggested the Germans were using TNT as the primary explosive in their shells whereas the British were using a more volatile substance for their shells. Apparently the shock of hitting, say, an armored belt would set off the British shells and not the fuze so they would explode without penetrating the armor first.

[@notsureyou]

Correct, the British were using black powder for the explosive filler and an over sensitive fuse as well. Which led to a significant amount of premature detonations. The British initially thought that the poor performance of the shells was perhaps due to the shells design or cap, so post Jutland they designed and introduced the Green Boy shell. The firing test against Baden that is mentioned in the video was the FIRST test with the Green Boy having a different explosive filler and fuse (German inspired fuse) to what was used during the war. They also used at least one Green Boy that was in service with the navy at the time (what would have been used during the war). Against the same type of amour which was the barbette (though a different barbette was targeted each time), The Green boy shell with the wartime explosive filler exploded on contact and DID NOT penetrate The Green Boy shell with the new explosive filler and fuse PENETRATED. Proving once and for all that it was the explosive filler and fuse that was the issue. The British then continue to work on the filler and fuse and had it perfected by the late 1920's.

IMHO Drach and Greg's Aeroplanes and Automobiles are the best technical You Tube sites.

[@DavidW27]

Shows the difference when the creator has a depth of subject knowledge and does some thorough research. A lot of you tube channels these days are someone reading out the Wikipedia page with a few random - and often incorrect - photos.

[@mpetersen6]

WWll Bombers does deep dives actually going into source data. Bringing up graphs and reports. Chris from Military Aviation History and History not Visualized are top notch too.

[@howardmaryon]

Fascinating stuff. I have always been interested in “terminal ballistics” and of course when a child I spent many happy hours shooting various airgun pellets into blocks of “plasticene”, which makes a very satisfying crater and penetration channel. I expect the admiralty brass enjoyed testing their shells with the same boyish enthusiasm.

[@nickraschke4737]

Those poor young blokes behind the armour.

[@the_phaistos_disk_solution]

Amazing! Great photographs.

[@roho10011]

Excellent as always. Thank you for great content like this!

[@robertmatch6550]

Time to watch a hard thing hit a hard place.

[@arieltimeshrine8137]

A WW2 version of this video would be splendid and most appreciated as a more practical-minded examination of how the march of armor and shell technology has changed their performance over that time period.

[@quaternarytetrad4039]

14:28 - Say no more! YES, do some WWII examples, please!

[@brainkill7034]

I think I speak for all of us interested enough to follow your niche channel in the first place: Yes, please!

[@MsSteelphoenix]

Very interesting, especially how penetration of the armour isn't necessary to cause havoc. I'd be interested in a WW2-focussed video!

[@massimookissed1023]

I always find it shocking that hard steel can look like it was plasticine when it was hit.

[@RichBarlow70]

I just visited the USS Missouri in Pearl Harbor. The 16" rifles are AMAZING . . . i'd love to hear more about WWII armor impacts!

[@saberdogface]

Legit question. Why don't naval guns use shaped charges to defeat armor plating?

[@douglasthompson201]

HEAT rounds from tank guns were/are occasionally used as such against bunkers and buildings, so it's not unprecedented, but the science of shaped charges was in its infancy at the end of capital ships gunfighting each other. Missiles have almost completely supplanted guns even in surface warfare, so no R&D money was spent on 16 inch diameter shaped charge rounds for naval guns. Some anti-ship missiles are equipped with them though, I bet.

[@kidpagronprimsank05]

Also ship compartmentalization itself more or less acted as space armour which makes shaped charge probably less effective. At least in terms of penetration, but biggest threat for these are probably secondary fire as Sheffield shows

[@MrNicoJac]

Oooh, yes I'd VERY much love a WW2 follow-up on this topic, Drach! 😃

[@magpilot7465]

Having a moderate understanding of British culture, I did pause to reflect on the extensive moral damage done by that No.6 hit on HMS Tiger to it's resident bakery dept. Quite underhanded of the Germans to target the scone and biscuit supplies.
