Amazing thanks, my grandfather was an engineer at chatham docks, sadly died trying to save the life of a friend who inadvertently fell into the water just after they left the security gate on shore leave! The friend could not swim so my grandad dived in and its believed he struck his head fatally. Still have the plaque given to my grandmother by the King.
I tried to save a friend when we were in gradeschool. He was bigger and stronger so he climbed me like a ladder and stomped me to the bottom of the pool. Luckily a much old and much much strong guy saw this and pushed Jack over to the pool edge where he climbed out. It all happened in such slow- motion, I can still see 3 of us standing watching Jack flounder.

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.
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.
Most definitely. Literate intelligent technically competent beings with the ability to explain clearly are a treasure. Thank you, Drach. You are a beacon of lucidity in a very cluttered content-scape. Greedily gobbling may be just a touch exaggerated, but not by much, of what happens when I heave into sight of one of your videos.
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...
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.
Excellent video, Drach! Your explanations were clear enough the a very non-engineer, political scientist could understand. Count me as a vote for further videos on this topic regarding WWII ships!
My takeaway: Given sufficient energyu-- Every elastic collision becomes an inelastic collision and Corollary: Newtonian mechanics become fluid mechanics
I was a GMG in US navy in the early, mid 80’s. As a child, I was fascinated with the type vessels you cover. I was shocked at what little armor our gun turrets were provided with. Different era, I understand, but I realized I didn’t want to be in a Savo Island, type battle. Lol
@trickydicky2908: I was a GMG in the late sixties, I so wanted to get aboard one of the big gunslingers that were still in service, like Oklahoma City or Newport News… no luck, I was sent to the brown water navy which was a hell of an adventure but I never got to be around anything bigger than a Browning M-2.
@JoshuaTootle 1/4” I suppose. Lots of sound-deadening foam, inside the turret, lol. The turret housing was there purely to protect the machinery and electrical bits, from seawater. Lol
SUPER INTERESTING! Battleships and their guns are fascinating bits of historical technology. The battles these ships fought are covered in minute detail, yet the actual, physical effect of their weapons on an unfortunate competitor is rarely ever explained. Good on yer Drach!! ; D
You have seen and felt the 16" Battleship Massachusetts Shell that slammed into the French Battleship in Moracco ,as I did in 1972 when I was 11 , it was so bizarre, I couldn't understand how the after end of it was so devastated , it was so deformed, so much missing and that Scalloped pattern of destruction made it look like a Meteor the damage was so extreme, but I was amazed how the front of the Projectile was so intact?
I’d enjoy watching as much content about projectiles and their impacts as you are willing to make, from WWII or any time period in which projectiles have been impacting ships
I concur. An analysis of shell hits on USS South Dakota or a study of Kirishima's impotency in the duel with Washington would be fantastic, for example.
Ive never been subject to naval gunfire, but I imagine being hit with a capital ships main battery would be very much consistent with "A significant emotional event"
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)
from a completely different POV, actual artillery operations are just plugging numbers into an app that gives you the angles to set on the gun (at least that's how Ukrainian artillery operates, and yes, it's a literal app on your phone)
I have a pdf saved somewhere of a detailed study talking about all of the failure modes and the physics involved for how the armor breaks apart. Very interesting - I'll try to find it if anyone is interested.
iVE always been interested in the LAYTE gulf action against i beilieve it was FUSO, being firied apon by WV with its new radar. What kind of power or penitration would have happened on the full frontal armor of FUSO from WW1 based guns on a ship coming straight at the guns.
Fascinating! Decades of interest in Navel history and that was the first time I had ever been shown the mechanics of shell fire and the effects on armor. yes please on a WW2 chapter and may I suggest a part three as to what happens with missiles and modern shipping and why the change over (apart from range) Thanks for the presentation
H.M.S. Tiger was a beautiful-looking ship. Her well-proportioned lines are very attractive. I especially like the layout of her tripod mast, bridge structure, and three funnels.
When at boarding school in the ‘60’s, the school was managed as a naval ship and many of the teachers were ex-RN. One particular teacher had been the commander on a destroyer, and was responsible for fire and damage control. If you wanted an easy lesson, all you had to do was ask him about how badly his ship was damaged in WWII, and he would give you precise details of each and every shell hit. Fascinating.
I love reading (hearing) names and anecdotes of engineers, craftspeople, labor, actual people who make inventions and advancements and labor to build these things. Im sure the metallurgy of naval armor has much to do with making steel and other metals for civil uses.
That slightly raggedhole in the turret reminds me of when I gradually drill through hard metal pipe with a cobalt drill tip and finally break through the first side and need to take a break and so does the drill engine before making the hole neater. Then I need to continue so that the bit passes through the pipe's other side.

Referring to Drach's introductory remarks... Never have I heard, or imagined hearing, so many qualifiers in such a short amount of time, and yet have them still be both intelligible and interesting (even amusing). Well, well done Sir!
The picture of the Battleship firing at 02:07 is using what type of propellant, Black Powder, Soot or is this another way of making smoke, did they not use smokeless powder bags or shells?.
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
Wow. Had no idea THIS is what a naval cannon could ACCURATELY do at THOUSANDS of yards. Bone chilling. Just, jaw on the floor, all those men facing it. Wow.
Yeah, my grandfather was a man like that. Nearly lost his life a half dozen times. He was always perplexed at how soft men became over time. I don't know how he would react to the current state of affairs.
A long time ago, when the Washington, D.C. Navy Yard was a working navy yard, sometimes they would build a turret, take it way down the river to a range, shoot it, weld it up, then shoot it again to test the patch. Kind of a combined R&D and QC. Take care.
WWII study would be fantastic. I am a retired USCG Gunnersmate Chief and serious history buff. The WWII "knife fights" are always interesting. Appreciate the post this is really interesting.
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.
I think this serves as an objective study in why battleship shells were historically so inefficient at sinking things even if the battleships got to open fire and hit, barring extreme size mismatches or magazine detonations.
@@tommatt2ski If you’re shooting at point-blank range obviously you’re going to not only hit way more often (even if Lee wasn’t at the helm) but also do more damage.
@@bkjeong4302USS Washington opened fire on Kirishima at 8,450 yards, and the two fleets were passing near parallel to each other traveling in opposite directions with the closest approach being just after when Washington fired her fourth salvo at 7,850 yards (which had an angle to target of only 5° from perpendicular). 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... Rather than "point blank", the battle occurred at ranges closer to the Maximum effective range of WA's secondary 5"/38 armament when firing anti-ship SAP shells of 13,800 yards (with 1" penetration at that range)...
@@tommatt2ski - You beat me to it. I was about to say, "...unless the shooter happens to be W. "Ching" Lee", in which case, the target could serve admirably as an illustration for the concept of *_perforation._*
Excellent presentation ! I have been hoping for a long time that you would do this. And yes, I would love to see more about the effects of world war II armor versus armament. Thanks again.
Need more channels actually deserving of a platform around. This guy has genuine value in reality. Tired of worthless media churned out for quick pennies. Nice channel dude.
Just to confirm, the first hit on Von der Tann from Batham is the same one described by the guest barrator in the Jutland video series as having "caused the hull to vibrate like a tuning fork"?
@20:47 to @21:34 - What’s the advantage of having the props angled outward like that ? Is it for quicker port and starboard maneuverability ? Like your turns of the ship begin earlier ?
I think Jean Bart, Kirishima, and South Dakota would be interesting to look at. 2 of the 3 survived and I believe Kirishima's DC log did or it's DC chief made a report afterwards which lines up with what divers have found on the wreck.
I've been looking forward to watching this... not only for the chance to see some rare photos of what naval shell damage actually looks like (I still hope someday to make a model of a battleship abandoned after a large naval battle), but because of the physics and the history of technological development involved!
26:15 Tangent: A Sherman tank moving closer to a German 88. At what angle, if any, considering time under fire will it be better to approach at an angle? Example: 30 degrees to make enemy's shells ricochet away?
11:06 Most of the full impact AP strikes will make round holes because at impact it's Kinetic Energy, and explosion. Unless a shaped charge is used the holes, cratering will be circular. KE= V^2*M/2 There's no resulting vector in this formula.
This episode highlighted many of the design treatise I've read about putting "de-capping decks/bulkheads" and "anti-spall bulkheads" integral to the hull.
Fascinating information Thank you, I learned so much I had no idea of about naval shells, and how they work. I never thought this would be interesting.
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.
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
In Willard Park, Washington Naval Yard, they display a turret face plate that had been earmarked for a Yamato class battleship. The Americans took it as spoils and fired a 16'' round at it. The result can be seen on the exhibit and imagining yourself to be one of the guys behind that armor plate the result is...toe curling. And not in a good way.
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.
Thank you for this lovely video and information. Please DO make one with WWII examples. Also, if you know, did the experiments performed on Baden had any merit in the decision to arm the King George V class battleships with more 14" guns instead of a larger caliber?
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.
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.

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.
Absolutely would love to see more information on the WWII-era examples of shell hits that were recorded with whatever you consider a sufficient level of fidelity to warrant even this level of casual analysis you find in a RUclips video.
6:15 , Midvale seems to have gone for a very blunt penetrator, but if the impact is more like a punch tool in a press rather than a knife or wedge function perhaps they could have gone more blunt with better effect? I think that Mr Szimanski said that the New Jersey's ap shells were fused for a one third second delay, seems an excessively long time, is that in line with other main gun munitions?
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.
Wonderful video as always. By the way, as you stumble upon German names quite often: Seydlitz is pronounced as "side lits", which is generally the case for "ey" in German.
Also, the cap was itself often capped by an aero-ballistic cap that was pointy. APCBC (Armour Piercing Capped Ballistic Capped) had the armour piercing shell, an armour Piercing cap, and then a Ballistic (pointy) cap on top of thr armour Piercing cap to provide minimum air friction and resistance

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 Like a tank.
@@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.

Most definitely. Literate intelligent technically competent beings with the ability to explain clearly are a treasure.
Thank you, Drach. You are a beacon of lucidity in a very cluttered content-scape. Greedily gobbling may be just a touch exaggerated, but not by much, of what happens when I heave into sight of one of your videos.
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...
Yes more examples and assesments of shell impacts. All of them that you have, can be a new series
I second that. Gib Moar!!!
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.
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.
Excellent video, Drach! Your explanations were clear enough the a very non-engineer, political scientist could understand. Count me as a vote for further videos on this topic regarding WWII ships!
My takeaway: Given sufficient energyu--

I was a GMG in US navy in the early, mid 80’s. As a child, I was fascinated with the type vessels you cover. I was shocked at what little armor our gun turrets were provided with. Different era, I understand, but I realized I didn’t want to be in a Savo Island, type battle. Lol
@trickydicky2908: I was a GMG in the late sixties, I so wanted to get aboard one of the big gunslingers that were still in service, like Oklahoma City or Newport News… no luck, I was sent to the brown water navy which was a hell of an adventure but I never got to be around anything bigger than a Browning M-2.
If a modern ship with radar and missiles ends up in a Savo Island scenario, something already has gone very, very wrong for both sides.
You had armor?
@JoshuaTootle 1/4” I suppose. Lots of sound-deadening foam, inside the turret, lol. The turret housing was there purely to protect the machinery and electrical bits, from seawater. Lol
@@trickydicky2908 PROTECT THE GUN!

Yes, please, of course! More information about shell impacts on WW2 ships. Awesome work Drach!
I would like to see another video on this subject: WW2 incidents, and maybe something on cruiser-level armor and guns.
Anyone else have his naval engineering playlist on repeat honestly endlessly fascinating
Yep... Do not watch another Drach Playlist they all make this effect 😂
Check out Asianometry for more incredible history videos. Many are tech-y but there are plenty of unexpected topics.
SUPER INTERESTING! Battleships and their guns are fascinating bits of historical technology. The battles these ships fought are covered in minute detail, yet the actual, physical effect of their weapons on an unfortunate competitor is rarely ever explained. Good on yer Drach!! ; D
You have seen and felt the 16" Battleship Massachusetts Shell that slammed into the French Battleship in Moracco ,as I did in 1972 when I was 11 , it was so bizarre, I couldn't understand how the after end of it was so devastated , it was so deformed, so much missing and that Scalloped pattern of destruction made it look like a Meteor the damage was so extreme, but I was amazed how the front of the Projectile was so intact?
Plastic deformation of metal is really cool effect to see in slow motion, friction stir welding of aluminum in particular. 😎
The visual aids in this presentation are great Drach.
I’d enjoy watching as much content about projectiles and their impacts as you are willing to make, from WWII or any time period in which projectiles have been impacting ships
Definitely interested in detailed analysis of more shell hits, especially from WW2, though more WW1 are also welcome!
I concur. An analysis of shell hits on USS South Dakota or a study of Kirishima's impotency in the duel with Washington would be fantastic, for example.
This must be the continuation to : Stop poking holes on my ships.. and I'm all for it!
Ive never been subject to naval gunfire, but I imagine being hit with a capital ships main battery would be very much consistent with "A significant emotional event"
If my early math teachers had told me geometry was the key to artillery I'd have mastered it straighaway......
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)
from a completely different POV, actual artillery operations are just plugging numbers into an app that gives you the angles to set on the gun (at least that's how Ukrainian artillery operates, and yes, it's a literal app on your phone)
Yes WW1 comparison to WW2 would be interesting. What was learned and what was dropped
I don't know, getting hit by shells seems a bit life threatening
Yeah, I've always recommended *not* getting hit, myself.
depends, are you a Warspite?
well they are generally not life extending 😅
Just dodge lol

iVE always been interested in the LAYTE gulf action against i beilieve it was FUSO, being firied apon by WV with its new radar. What kind of power or penitration would have happened on the full frontal armor of FUSO from WW1 based guns on a ship coming straight at the guns.
Definitely more examples of damage. Fascinating, and your analysis is valuable and appreciated.

@@tomhsia4354Da, Comrade!! FIRE!
Fascinating! Decades of interest in Navel history and that was the first time I had ever been shown the mechanics of shell fire and the effects on armor. yes please on a WW2 chapter and may I suggest a part three as to what happens with missiles and modern shipping and why the change over (apart from range) Thanks for the presentation
H.M.S. Tiger was a beautiful-looking ship. Her well-proportioned lines are very attractive. I especially like the layout of her tripod mast, bridge structure, and three funnels.
When at boarding school in the ‘60’s, the school was managed as a naval ship and many of the teachers were ex-RN. One particular teacher had been the commander on a destroyer, and was responsible for fire and damage control. If you wanted an easy lesson, all you had to do was ask him about how badly his ship was damaged in WWII, and he would give you precise details of each and every shell hit. Fascinating.
I love reading (hearing) names and anecdotes of engineers, craftspeople, labor, actual people who make inventions and advancements and labor to build these things. Im sure the metallurgy of naval armor has much to do with making steel and other metals for civil uses.
That slightly raggedhole in the turret reminds me of when I gradually drill through hard metal pipe with a cobalt drill tip and finally break through the first side and need to take a break and so does the drill engine before making the hole neater. Then I need to continue so that the bit passes through the pipe's other side.
Yes on WW2 hits. Also yes if you can find and discuss testing results with cool pictures.
I’d proudly consider this a worthy lecture on ‘Naval Ordnance’ for the US Naval Academy. The mids would love your style of presentation! Thanks!

Who doesn’t love hearing what happens when high velocity armor piercing shells hit armor plating?
Referring to Drach's introductory remarks... Never have I heard, or imagined hearing, so many qualifiers in such a short amount of time, and yet have them still be both intelligible and interesting (even amusing).
Well, well done Sir!
Drach: "What happens when a shell hits a battleship?"
Me: "Physics!" 😁
The laws of physics giggle and then laugh at us....
The picture of the Battleship firing at 02:07 is using what type of propellant, Black Powder, Soot or is this another way of making smoke, did they not use smokeless powder bags or shells?.
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
There is allot of powder gas/smoke.
Mmmmmmmm I wonder if black was used? If you can get a date on that pic we then could tell.
Very educational! I never thought this deeply on what actually happens when a shell hits armor. Thank you!
Another great video, I always enjoy your technical commentary, looking forward to the next one.
Wow. Had no idea THIS is what a naval cannon could ACCURATELY do at THOUSANDS of yards. Bone chilling. Just, jaw on the floor, all those men facing it. Wow.
Yeah, my grandfather was a man like that. Nearly lost his life a half dozen times. He was always perplexed at how soft men became over time. I don't know how he would react to the current state of affairs.
A long time ago, when the Washington, D.C. Navy Yard was a working navy yard, sometimes they would build a turret, take it way down the river to a range, shoot it, weld it up, then shoot it again to test the patch. Kind of a combined R&D and QC. Take care.
Drac have you looked at the damage report from S. Dakota. That would be a good one to do from WW2 that has a lot of good details.
A very informative and detailed analysis of Naval gun effects upon armour in the WW I era!
WWII study would be fantastic. I am a retired USCG Gunnersmate Chief and serious history buff. The WWII "knife fights" are always interesting. Appreciate the post this is really interesting.
Oh... my.... how I have waited for this video. Thank you drac
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.
I think this serves as an objective study in why battleship shells were historically so inefficient at sinking things even if the battleships got to open fire and hit, barring extreme size mismatches or magazine detonations.
USS Washington: " I beg to differ....SIR"!!!
@@tommatt2ski
If you’re shooting at point-blank range obviously you’re going to not only hit way more often (even if Lee wasn’t at the helm) but also do more damage.
Depends upon what you're trying to sink
@@bkjeong4302USS Washington opened fire on Kirishima at 8,450 yards, and the two fleets were passing near parallel to each other traveling in opposite directions with the closest approach being just after when Washington fired her fourth salvo at 7,850 yards (which had an angle to target of only 5° from perpendicular). 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...
Rather than "point blank", the battle occurred at ranges closer to the Maximum effective range of WA's secondary 5"/38 armament when firing anti-ship SAP shells of 13,800 yards (with 1" penetration at that range)...
@@tommatt2ski - You beat me to it. I was about to say, "...unless the shooter happens to be W. "Ching" Lee", in which case, the target could serve admirably as an illustration for the concept of *_perforation._*
Excellent presentation ! I have been hoping for a long time that you would do this. And yes, I would love to see more about the effects of world war II armor versus armament. Thanks again.
Fascinating! Do the WW2 version.
Need more channels actually deserving of a platform around. This guy has genuine value in reality. Tired of worthless media churned out for quick pennies. Nice channel dude.
Just to confirm, the first hit on Von der Tann from Batham is the same one described by the guest barrator in the Jutland video series as having "caused the hull to vibrate like a tuning fork"?
Excellent - thank you! Please do a WW2 episode as well.
@20:47 to @21:34 - What’s the advantage of having the props angled outward like that ? Is it for quicker port and starboard maneuverability ? Like your turns of the ship begin earlier ?
I think Jean Bart, Kirishima, and South Dakota would be interesting to look at. 2 of the 3 survived and I believe Kirishima's DC log did or it's DC chief made a report afterwards which lines up with what divers have found on the wreck.
Very nice. I always love battle damage assessments.
I've been looking forward to watching this... not only for the chance to see some rare photos of what naval shell damage actually looks like (I still hope someday to make a model of a battleship abandoned after a large naval battle), but because of the physics and the history of technological development involved!
26:15 Tangent: A Sherman tank moving closer to a German 88. At what angle, if any, considering time under fire will it be better to approach at an angle? Example: 30 degrees to make enemy's shells ricochet away?
Yes. Please, I would love to see dara on WW2 impacts.
11:06 Most of the full impact AP strikes will make round holes because at impact it's Kinetic Energy, and explosion. Unless a shaped charge is used the holes, cratering will be circular. KE= V^2*M/2 There's no resulting vector in this formula.

This episode highlighted many of the design treatise I've read about putting "de-capping decks/bulkheads" and "anti-spall bulkheads" integral to the hull.

Fascinating information
Thank you, I learned so much I had no idea of about naval shells, and how they work.
I never thought this would be interesting.
Legit question. Why don't naval guns use shaped charges to defeat armor plating?
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.
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
Fantastic and well in depth, would love to hear more. Well done!
Really enjoyed. Would like more when able
Still the best intro in all of youtube.
In Willard Park, Washington Naval Yard, they display a turret face plate that had been earmarked for a Yamato class battleship. The Americans took it as spoils and fired a 16'' round at it. The result can be seen on the exhibit and imagining yourself to be one of the guys behind that armor plate the result is...toe curling. And not in a good way.
Point blank range 90 degrees the only way the armor could be penetrated ever 😉
Yes was point blank
@@JeffEbe-te2xs in other words that says a lot about how better the armor was it was rated too stop 18inch shells
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.
Thank you for this lovely video and information. Please DO make one with WWII examples. Also, if you know, did the experiments performed on Baden had any merit in the decision to arm the King George V class battleships with more 14" guns instead of a larger caliber?
Time to watch a hard thing hit a hard place.
I was waiting quite a while for such a video. Thatnk you very much, highly informative. Will share it with my community... 😊
Yes please do another video of shell impacts.
Fascinating and insightful as usual.
I always find it shocking that hard steel can look like it was plasticine when it was hit.
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.
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.
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.
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.
Absolutely would love to see more information on the WWII-era examples of shell hits that were recorded with whatever you consider a sufficient level of fidelity to warrant even this level of casual analysis you find in a RUclips video.
14:28 - Say no more! YES, do some WWII examples, please!
I think I speak for all of us interested enough to follow your niche channel in the first place: Yes, please!
6:15 , Midvale seems to have gone for a very blunt penetrator, but if the impact is more like a punch tool in a press rather than a knife or wedge function perhaps they could have gone more blunt with better effect? I think that Mr Szimanski said that the New Jersey's ap shells were fused for a one third second delay, seems an excessively long time, is that in line with other main gun munitions?
“ *Stop poking holes in my ship: Part III* “
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.
I would like another lesson on this subject, please.
Wonderful video as always.
By the way, as you stumble upon German names quite often: Seydlitz is pronounced as "side lits", which is generally the case for "ey" in German.
Surprised by how blunt the armor piercing cap seems to usually be
at those sizes it just has to be really hard and really dense rather than pointy
Dead on 90 degrees a sharp pointy tip aids penetration. But it doesn't take much of an angle before it causes more problems than it's worth.
@joearnold6881 look at hydraulic metal hole punches. I used one at work. It was flat with a small point
Also, the cap was itself often capped by an aero-ballistic cap that was pointy. APCBC (Armour Piercing Capped Ballistic Capped) had the armour piercing shell, an armour Piercing cap, and then a Ballistic (pointy) cap on top of thr armour Piercing cap to provide minimum air friction and resistance
Very interesting, especially how penetration of the armour isn't necessary to cause havoc. I'd be interested in a WW2-focussed video!
