Will a video ever be done on Naval Defenses of the American Coastline? Or even British, French, German, or even Russians. Also I was wondering if a Video could be done on the USS Georgia BB-15
Possibly a question you’ve answered before, but what difference would have been made to the pacific campaign had some or all of the standards been absent at pearl harbour? I mean it was quickly apparent the aircraft carrier was the major means of projecting sea power in WW2 so much as the temporary loss of the battleships was a shock, did their loss really mean a great deal given they were too slow to keep up with the CVs and the US had two classes of fast battleships soon to join the pacific fleet?
Hey Drach. I know that the 1.1 inch gun mounts ended up having a Bofors mount put in the same place instead of the 20mm. What was the decider to put it in the first category as opposed to the “medium”, where it would probably be the worst?
@@_nanking5374 like it take times to train up a soldier and unlike China, the US won't have enough man power to trade kill to kill And they ain't drafting anymore
A USN below-decks sailor was told this about AA gun activity: 5" guns firing: "Maybe they're not after us." 40mm guns firing: "Here they come." 20mm and machine guns: "Hit the deck plates!" At the Battle of Midway, he heard everything firing and wondered what was going on topside.
@@neddyladdy lol, i had thought so.. but i have had enough people in youtube comments make such comments seriously that i figured better safe than sorry :P , nonetheless i assure you its well worth the few hours or such.
The amount of shrapnel laying on the seafloor of the Western Pacific expended by the US Navy would probably be equal to the steel required to build a Yamato.
@@timengineman2nd714 indeed. Probably more then that, as every 5 inch/38 caliber gun put out half a ton of shrapnel a minute, there is probably a Yamato worth from just all those firing
65,000 tons displacement, half a ton a minute, 16 guns. An Atlanta class cruiser can spit out a Yamato in shrapnel in 135.4 hours of constant firing, or 5.64 days. If you go with the entire class, your down to just under 17 hours using all 8 ships in the class.

Have we not forgotten airships here, have we? Though they are not air "planes", they are definitely air "craft" ...and then there is the Ekranoplan, the soviet ground effect vessel. Since I'm already on the run: Hovercraft. What are those?
@@ringowunderlich2241 In the US Navy, I believe the LCAC hovercraft are considered "boats" or auxiliary craft, not "ships". They don't get names, only numbers.
It is one of the most attractive AA mounts, and like an underappreciated amount of Italian tech in WW2, actually a pretty good weapon, just with a couple of significant issues that prevented it from reaching it's full potential.
I'd like to suggest an episode about battleship's seaplane launch systems, history and operational use. I feel there is a lot of interesting detail there that gets a bit brushed over by carriers and radar. I always found it a bit romantic to carry a dainty little airplane on a big gun floating fortress.
Fun fact: Cooks on naval ships have to prepare meals even in the middle of battle. During World War 2 the cooks on USN warships always kept an ear out for the different AA that their ship was using by its sounds and would respond accordingly 5/38: *BOOM BOOM BOOM* = Kalm 40mm: boombadoombadoombadoombadoom = Kalm 20mm: Ratatatatatattatatatatatatatatatatatatatata = *PANIK!*
My Dad was an RN AA gunner, In the first action, he told me was a time of pure terror he got through by doing his job by the numbers. His best friend was killed right before his eyes. He told me after that things became personal and he took great pride in downing enemy planes. Strangely he never thought of killing the men in the planes the plane itself became the object of his fury. Although after the war he said the enemy pilots were just doing their duty like him. My Dad was my hero and I still miss him.
You were truly blessed, and so were his shipmates. Sounds like he is still your hero. Such men make eternity easier to look forward to. May we all meet there one day.
My grandfather was motivated by fury as well, and a desire for vengeance, though not simply because of the loss of a friend. He was a Pearl Harbor survivor. He was there when Japan mercilessly brought the war to us. He, like so many others, was eager to strike back. But killing another human being changes you. It’s almost like a little bit of you dies with them. He was forever haunted by the things he saw and those he killed. It was only a few years before his death that he finally spoke about the war. I like to think that meant that he was finally at peace with what happened in the end. He never considered himself a hero. He just saw himself as a soldier that did his duty, even if it meant walking through the gates of hell onto a God forsaken battlefield. I admired him for that, and I’ll always miss him.
Another fun thought is about armour and penetration: modern tanks have frontal armour and firepower that faaar outclass that of WW2 battleships, at least on paper. You know, effective frontal armour approaching 1 meter equivalent of RHA, and guns that can penetrate such armour. The only difference is, a tank gun can't punch through armour that thick at 30km range xP I really wonder what would happen to a Leopard 2A6 or a T-90MS if they were slapped in the face by an AP salvo from 16'' /50cal guns at that range. Would they bounce off or shatter? That'd be quite the thing to see
@@johnfrancisterne1072 and look how times has changed... Today most deck guns are actually lower caliber than modern tank guns (although typically they are higher velocity weapons, and quite often quick-firing revolver cannons) And modern Tank guns finally reached caliber used on WWII dedtroyers.
@@mancubwwa well as there were some tanks of Russian and German origin that equaled or bettered the us destroyers ( jagtiger kv2 isu 152 and the is series of tanks ) all had guns greater than 120 mmr and some up to 152mm
@@Paveway-chan 16" shells would probably leave a crumpled mess of steel, ceramic tiles and bits of NERA in an explosion crater by virtue of them being so massive. 1200 kg AP shell moving at those speeds will not care about 50-60 tonnes of an obstacle.
While as an American I am happy that the 5"/38cal won overall, the idea of that UK 5.25"/50cal literally sniping Japanese craft out of the skies pleases me immensely.
The 5 inch/38 gun was far more workable and a marvel of engineering, however in the early to mid 50s, the 5.25 had more development potential. It became a truly lethal weapon with remote power control and power ramming on Anson, Vanguard and Bellona class Didos
For those who keep memeing about the 18.1" sanshiki shells for the Yamatos, remember this: the late Eugene Slover's web site (a treasure trove of official publications for the Iowa class) has official AA range tables from New Jersey's Vietnam cruise... for her main battery. Yes, the US Navy did actually work out antiaircraft range tables for the 16"/50 caliber gun, since VT fuzes made it *technically* possible to use it against aircraft...
Loading time plus slew and such . . . use radar to get where and when, then, "Wait for it . . . wait for it . . . . Fire!" If it had a mine charge/fragmentation shell engineered for purpose, who needs missiles?
It should be noted that, in practice, the characteristics of the AA gun directors are just as important as the guns themselves. A 5"38 with radar direction is a very different beast than a 5"38 fired with dead reckoning.
Reminds me of my favourite quote from the old robo voice about US AA doctrine: 'Us there an empty spot on the ship? Why is there an empty spot on the ship? Put a gun on it you idiot.' Turns out deadpan robots can do snark well.
During my first year aboard DD540 ,a Fletcher,I was in charge of 7 motley apes, in the ammo compartment below #5 AA gun. Being the tallest,it was my job to push clips of 40's, up thru a slot above my head. The gunners would grab them and drop them into slots of the guns,where they would automatically fire,as long as the gun Captain,and the Sight Controller each held their firing switch on Fire mode. We saw nothing from inside. One time our ship was missed by 2 bombs, which exploded in the water, missing us by about 5 feet. The concussion blew out our lighting,and blew a couple of control boxes loose from the bulkheads.that caused them to swing by the cables, in the dark, knocking a couple of guys down. Thinking we were hit,I opened the hatch.There was just blue sky filled with AA puffs, and soon the damage control team came and secured the Control boxes. After a year of that GQ station, I was assigned as sight-setter on #AA1 Sight . This was right on the bridge where I could hear some orders, and see the action. Officers previously were assigned to that position. I was FC2C at the time. We were a lucky ship, with the 3rd. or 5th. Fleet, involved with everything starting with Saipan, and ending with 'The Bombs'. We were one happy bunch, and were shocked when we realized we had survived.The Captain celebrated by giving us a straight shot of Bourbon!
You don't see too many 102 year old people posting things on you tube . Figure the battle of saipan was in July of 1944, and the average second class petty officer in the navy in 1944 was 23 years old that would make you 102 years old when you posted this. Sorry, my friend but I have to call bullshit on this one.
USN to Gun Manufacturers: "Give me all the AA Guns you Have" Gun Manufacturers: Ok USN: Wait. I think what you believe you heard was give me a lot of AA Guns. What I actually said was Give me All the AA Guns you Have.
The Japanese and Italians have always competed for the "worst machine gun" title. Not all of their machine guns were terrible, mind, but the bad ones were REALLY bad.
Probably would have helped to point out that the role of the Japanese 25mm was filled by the 37mm for the Italians, and for the role of the Italian 20mm guns, the Japanese were stuck with a 13.2mm MG lol
LOL especially as Navy ships often had way more of them stuck on than they were supposed to receive. Both on land and at sea the American trait of "borrowing" equipment not authorized was very common.
The 20mm Oerlikon was produced in absolutely massive numbers during the war. somewhere between 125,000 and 150,000 barrels, and some variation of the original gun are still being produced and in use in 2020.
In fairness to the Chicago Piano, it actually performed surprisingly well despite all of its problems. Sure, they were glad to replace them as soon as they could, but the fact that they actually shot down a few planes (in one case, a plane that was in the middle of a dive!) is impressive.
@@LazyLifeIFreak The Bofors 40mm was a pre-war design. The Swedish navy gave Bofors the job of designing a new AA gun in 1928 and the new gun was ready for production in late 1933 though a lack of funds meant that it became the m/36 rather than the m/33 in Swedish service.

@@joshuahadams An incendiary shotgun shell. Basically it was an 18inch time fused shell, that would detonate, hurling out a mass of thermite filaments in a conical blast intended to flat out incinerate anything within the blast zone. To my knowledge, they were never fired in combat and wouldn't have been especially effective if they had, being more of a firework show than an actual weapon
@@weldonwin They were used (google san shiki for more). Though they were sufficiently awful that they were rarely used, as it was difficult or impossible to man the actually useful AA guns while the main battery was being fired.
@@joshuahadams Type 3 incendiary shrapnel, produced all the way down to 8" caliber for cruiser guns. Not terribly effective against all-metal aircraft, even if you do time the fuse correctly.
Longest range and largest rate of mass thrown downrange does indeed seem to have been the IJN 46 cm guns firing Sanshiki Model 13 “Common Type 3” antiaircraft incendiary (IS) rounds. The USN Air Action Reports for the Battle of the East China Sea indicate that 11 of the 16 squadrons making attacks on Yamato on 6 April 1945 came under main battery fire. This involved both air-burst shells and shells fired into the water in front of attacking torpedo bombers. Main battery AA fire extended out to ten miles. No indication of any USN aircraft harmed by main battery fire. As the purpose of the Ten Go attack was to beach the battleship and shoot up the invasion fleet, pointlessly expending so much ammo swatting at gnats seems puzzling. During the actions off Guadalcanal the IJN evidently used Type 3 IS projectiles for both shore bombardment and shipping attack; USS Quincy apparently came under fire from IS shells (Hornfischer, 2011, "Neptune's Inferno" p.71). There are stories of unburnt “rubber thermite” filled sub-munitions "littering the decks everywhere" after such attacks. As recounted by Hornfischer (p.327) sailors on the USS San Fransisco found it a bad idea to put one in your hip pocket as a souvenir as they were sometime still active and couldn't be put out with water. Interesting concept, using sub munitions during Naval engagements: Maybe Drach could do a story on this?
While true, I believe he deliberately did not take technology such as proximity fuses and radar targeting into account. This made the comparison between guns of different nations fair, because otherwise the nation with a worse gun, yet better technology in other respects would win every category.
@@MoeZiilla A gun, any gun, is a system. Ammunition is part of that system. You can't make a comparison by saying "oh, the firing mechanism on this one was marginally better than on that one" while ignoring that one had exponentially more effective ammunition is a fool's errand.
Before the U.S. entered World War Two, my grandfather worked as an iron miner in Lyon Mountain NY for a while. Later on, he hauled breach blocks for 90mm AA guns from a manufacturer that used Lyon Mountain iron to Chelmsford MA. When he was drafted into the army, he served as an anti-aircraft gunner... using 90mm guns. So, there's a chance that he actually dug up some of the material for his gun.
My Dad was fire watching in H&W during the shipyard blitz on Belfast.He decided the safest place was beside a navy vessel which was putting up a barrage. He found that quite dangerous from flying cartridge cases which he nabbed to store his nails they were roughly1 1/2 wide and 4" long.I played with them as a child. Unfortunately I no longer have them .
Two entries I kind of expected to see: 1. The German 12.8 cm FlaK 40. Did they really never bolt one of those to a ship? Quite possible, I would have expected them to, though. 2. The Japanese 460 mm. Mostly for honorable mention & comical relief. In any case thanks a lot for the very interesting content as always.
As I'm watching this from my father's basically death bed I find it strangely soothing. This vid gave me a lot of answers I never knew I needed. Thnx, please just keep up the stellar work. These kind of knowledgeable and strangely entertaining vids have made this terrible time bearable for me. Just thank you.
Drach: "Anti aircraft machine guns were largely useless." One thing you fail to realize is us Americans and our love affair with the M2 Browning. It is the only modern weapon that is still in use after a 100 years with very little tweaks, and we will put it on an MRE if we thought it would help!
@@Kromaatikse pretty effective against the Germans and Italians too. Indeed, the transition to cannon wouldn't come for another decade or so, helped by the unreliability of early US 20 mm cannon designs and the lack of heavy bombers to shoot at.
It's odd the Japanese held on to the 25mm. Their aircraft had several good cannon designs around that size that were essentially scaled up Browning designs. They also almost certainly had captured examples of the Russian 23mm, another excellent light AAA autocannon design.
I wish the actual statistics were provided, i.e., "399 rounds per minute, rather than pretty good or average, etc. The range is "2300 meters instead of somewhat pretty fair, but not as good as the Swiss 67 mm, which is slightly less but O.K.ish, etc., etc." More objective, less subjective, or opinion-only. Love the channel, though.
An hour long discussion of AAA fire control advances in WW2 would be interesting. Radar and proximity fuses. Also, how effective were fuse setting devices!
I'm sure they wanted to develop quad 5.1 inch turrets too. I can't begin to imagine how badly that would train and fire without remote power control and power ramming (only post war viable) given how atrocious the triple 4 inch gun was as a purely anti surface weapon
Not for drach maybe but an anti tank weapon version of this video would be stellar. Super Light: Hand held Light: up to 40mm Mid:up to 75mm Heavy:76mm plus
So glad you're covering this in some detail. Almost every one of the hundreds of ship and class descriptions you've done refers to oar-lickers, bifurs, bofurs, bombers, pomades, and I know not what else. This will be a big help.

Often wondered how the US 1.1 inch ‘Chicago Piano’ (replaced as soon as possible when its shortcomings became apparent) compared with the Japanese 25mm (a gun which continued to provide unsatisfactory results into 1945). Thank you for providing your detailed analysis and ranking.
The major consideration for the longer-ranged weapons particularly is the capability of the fire-control systems to which these weapons are attached. Many of the small weapons listed are "one-man/one-vote" where, with minimal supervision, each gun is fired by its one or two-man crew at whatever they personally think is the best target within their arc of fire and range. The advent of small "angle-rate" calculators built into their guns later in WWII in many US 20mm mounts, at least, gave some better chance of hitting by using a fixed average expected range and the rate that the gun was being moved in elevation and bearing to provide the other bits of data for calculating a lead angle (in both bearing and elevation) to increase accuracy. Most larger weapons had eventually separate directors added that could control its dedicated gun mount or, depending on the system design, several nearby mounts, and these greatly added to their effectiveness, particularly systems designed for director control from the start (US Navy 5"/38 gun on its several mount variants). When radar came into the picture, weapons that could use it got much better, since range, in particular was now extremely accurate, though the narrow radar beam-width to get good angular position and rate tracking took longer to perfect. When "2nd order" rate tracking became the norm for aiming calculations, where, once a target was being tracked properly, its internal "virtual" target inside the calculator's mathematical "motion space" was set to allow the target to coast at its last good rates, things got much better for AA tracking systems. Now, only if the target began to diverge from its expected track due to it changing speed and/or maneuvering, did the calculator need to adjust this "coasting" internal virtual target. This made updates to keep up with a target MUCH faster and made it more difficult for a target to "break lock" even with chaff and jamming unless it did violent maneuvers while hidden, since if it came back into the radar's view anywhere near its old expected position, the radar, which was moving its dish as if it was still tracking the target anyway, would just lock back on as if nothing had happened. Older radar systems with simpler calculations could not do that very well. Note that not only had the calculators have to be accurate, but fast enough to keep up with fast-moving, maneuvering aircraft to get enough lead to hit the target (aiming where it is now is obviously not viable), but the speed of transmitting the information from the tracking systems (optical and/or radar) to the calculators and their fast transmission of their orders to the weapon mounts had to be acceptable. "Follow-the-pointer" systems where the information, usually the orders from the calculator to the weapon mounts due to their weight, had to go through a person who looked at a dial reading from the calculator and did his best to keep up with it using his hand and foot controls, was fast enough for firing against slow surface targets (though accurate "eyeball" matching of the orders dials was not always the best) but it got more and more ineffective at longer ranges against high-speed aircraft, since even a small error would mean that the shell being fired would diverge from the aim point too far to be reliable, even when the VT (proximity) fuzes were adopted, though they greatly helped, of course. Complete Remote Power Control, where the calculator could in Remote/Director Control take over the gun mount aiming, with the human there only for backup or special things like shore bombardment, was the rule in the US Navy at the end of WWII, with Germany and, to a lesser extent, Britain also having this RPC capability at least in some gun systems, which eventually completely replaced humans in gun mounts, even small mounts, after WWII. Rating complete fire-control systems (weapon, sensor, calculator, location on the ship) is not a simple thing, though, even if you precisely know the targets it was made to destroy.
@@marcusborderlands6177 I do that in some cases. Depends on how much effort I take to do a comment. You are correct that I should do it more often. Thanks.
One hour of pure, unadulterated, detailed and (ostensibly) explosive content! Drach, this might sound silly but.... you couldn’t imagine how much I needed this. Just something to listen to and enjoy whilst disregarding the cares of the world. Thank you sir.
I was hoping you might mention the 18.1 inch sankhiki anti-aircraft shells fired by the Yamato / Musashi battleships . Possibly the heaviest AA rounds , and "dual purpose" guns ever to see service . Both spectacular to witness , and spectacularly ineffective . Almost worth an episode in themselves , although I don't know if much reliable data still exists for them .
This was a very informative video. However, if I can state a recommendation, it would be this in assessments that are rather heavy on the technical side could use a little bit of numbers on the screen to keep track of things. On many occassions I found myself rewinding to a previous gun in order to pick up a number to compare it to the next gun in line. A few numbers and names on screen would help _immensely_
Teacher: Did everyone do their AA installation homework? US: the top student who grinded their soul into their homework UK: not that much but did it pretty well Germany and Italy: just your joe average classmates with joe average homework Japan: "Wait bruh there was homework?"
Not sure the US was so much the top student, as it was the student who was surprised to find his favorite hobby was actually a graded activity. He just loved guns, he didn't know it was going to be graded.
Great! Another excellent video topic by the Drach-master! Always wanted an in-depth discussion about the rapid advancement of fire-control and anti-aircraft weapons and tactics!

My uncle was in charge of the anti- aircraft guns on an LST in 1946. He would have loved this channel. Pity he missed it by as year of two. But he also missed them war but a month or two, so he didn't do too bad.
Great video as usual. The amount of work you put in is stunning, really. Id really love to see a video about the peculiar and weird AA weapons, such as the AA shells of the yamato etc etc.
This video cant help but remind me of a Kancole story I read which had the following line "Bofers is the new black" because let's face it damn near everyone who could dressed their ships in Bofors is some cases the ships' crews did it, never mind where they found it, it's here now.
In medium category shell weight might be over empahasized. These are all 37 or 40mm HE rounds fired directly at the enemy, thus practically any hit would be fatal to the aircraft these would be usually firing at. The shell weight does affect muzzle velocity and range, but those are already separate categories. I should also note the German M42 and M43 are far lighter weapon systems than those higher in the category. Perhaps not enough to make a significant difference on most naval mounts, but M43 was also used on land. Both towed mounts and mounts on armored vehicles were relatively simple for it thanks to the low weight.
One point of note that may be a neutralizing effect is barrel life. The Italian 20mm may have been elevated from its low ranking to a respectable ranking, simply because it maintains its accuracy longer. The high rate of fire guns and cannons with shot out throats and rifling would be lowered in ranking if they couldn’t hit the broadside of a barn.
Masterful work as always. Two thoughts, there was a 3 inch gun mounted on Royal Navy A-I destroyers in lieu of the aft torpedo tubes and on V/W long range escort conversions. I guess it belongs in the bottom category. I think the Italian 100mm deserves its own category, I've read it was "deemed unsuitable for aimed fire" meaning used to fire a barrage and hope you maybe hit something. They were replacing them with 37mm guns because 37s actually could hit something....
was missing all the stats you were running through for the guns, would have loved it if you put those on screen as well! Other than that an excellent video as usual!
@@dariomasi9 Exception that proves the rule. Just because it shot down some planes doesn't mean it was a good gun - the 1.1" Chicago Piano managed to shoot down some planes too, but it was awful.
@@TexasSpectre Thats not what i was saying... Just that it wasnt such an awful weapon as both Drach and many commenters say it is. It was better than the japanese 25mm despite what Drach said (he tried to sugarcoat how awful it was by not dweling into just how awful the mounting requirment was) It was "bad" when compared to the oerlikon and late war german 20mm, it was still not the worst gun of its caliber nor other light guns, dont even get why it was compared to medium caliber guns since the requirments are very different. The breda 20mm dindt just "shoot down some planes" it was a clear threat to any plane it its range unlike the 25mm and the Piano gun, i can count around 30 ish confimed planes shot down by it alone, without the help of medium caliber weapons, wich is quite a lot for a gun of its size.
@@dariomasi9 I don't know why people take Drach as any sort of authority, he just repeats old bullshit from other sources and packages it up for videogame-obsessed idiots (see: the idea of 'scoring' AA guns by a bunch of arbitrary numbers instead of actual historical data)
I wanted to say that everyone who loves these videos PLEASE become a Drachinifel Patreon! This guy does such a great job and deserves your contribution!
Hey Drach, did some digging around and found a story in Air Force News (official US Government site) that claims the cost per round of 40mm AA rounds was $8 in 1940’s dollars. That figure is for training rounds though.
I knew the 5"- 38 was going to win, I was waiting for him to talk about the radar proximity fuse as the main reason why. He never did and that made me sad. :(
Makes sense to me. Polish history is like a bad porno, every opportunity the neighbours fuck them. Maximum firepower in a transportable platform? They'd love it.
If my memory serves me, the US submarine force took a liking to the 5" 25 cal. for deck mounted weapons. Dunno how much water proofing it required but it beat the schnizzle out of the older 3" that created underwater drag than defense on a boat.
I believe the "wet mount" for submarine deck guns required the optics to be in a removable module, so they were not subject to submerged pressure. The gun barrel received a muzzle plug to complement the breech - probably didn't keep seawater out entirely, but would have reduced the extent to which internal coatings were washed away and marine growths built up while submerged. The deck guns were not for defensive purposes, but rather for engaging targets that were too small to be worth a torpedo, or for finishing off a damaged target. The 3-inch gun could do that, but took a long time and a lot of ammo to do it. The 4-inch gun was significantly better. Some boats received 5-inch or even 6-inch guns, which could be considered overkill.
Then there's the British M-class Submarines, 3 subs where made and they mount single barrel 12" gun as deck guns like the French Surcouf 8" gun submarine
The only thing I wish you included was the yards in range, as I have no idea hoe far away a WWII navel battle is as now a days a missile can go destroy its target over the horizon and you dont have to worry about powder magazines exploding.
Hey Drach, good video! If you look there’s some footage here on YT of 5”/38 twin mounts in action during WW2 on an Essex-class carrier. To quote a certain RUclipsr, they put a hilarious amount of shells in the air. Looked quite devastating really, which begs the question: “Does a kamikaze pilot REALLY care much about the status of his underwear?”
If you walked into an anti-aircraft showroom, you would buy 5"/38. It's lovely. It's elegant. It's beautiful. In the world of heavy AA, it is the Saville Row suit, the Rolls Royce Corniche, the Chateau Lafitte 1945. It is the heavy Anti-aircraft gun Harrods would sell. What more can I say?
I am not sure if the Oerlikon 20mm is better than the C/38 by that big of a margin. Both had a max rate of fire of 450 rpm, with the difference in practical rpm being the magazine size. Since light AA will not be shooting all the time during an engagement, I think there will be time for loaders to change out magazines. Larger magazine does carry an advantage, but I don’t think it is as much as the practical rate of fire reflects. Aside from that, Oerikom 20mm had a muzzle velocity of 820 m/s and range of about 0.9-1.0 km against low flying aircraft, while the C/38 had a muzzle velocity of 900 m/s, very high among light AA, and a range of 2.2 km against aircraft, much longer than the Oerlikon.

Bofors, pom-pom, Oerlikon. They were all in a day's work for my dad as an Ordnance Artificer. Thank you so much for this.
My Dad was an RN AA gunner, In the first action, he told me was a time of pure terror he got through by doing his job by the numbers. His best friend was killed right before his eyes. He told me after that things became personal and he took great pride in downing enemy planes. Strangely he never thought of killing the men in the planes the plane itself became the object of his fury. Although after the war he said the enemy pilots were just doing their duty like him. My Dad was my hero and I still miss him.
You were truly blessed, and so were his shipmates. Sounds like he is still your hero. Such men make eternity easier to look forward to. May we all meet there one day.
May he rest well in Vahalla, with my grandfather, an American Paratrooper.
And may he rest easy. Its men like your father, that allow us to live like we do today, and for that they have my eternal thanks.
I've never met your father, and he's my hero as well.
My grandfather was motivated by fury as well, and a desire for vengeance, though not simply because of the loss of a friend. He was a Pearl Harbor survivor. He was there when Japan mercilessly brought the war to us. He, like so many others, was eager to strike back. But killing another human being changes you. It’s almost like a little bit of you dies with them. He was forever haunted by the things he saw and those he killed. It was only a few years before his death that he finally spoke about the war. I like to think that meant that he was finally at peace with what happened in the end. He never considered himself a hero. He just saw himself as a soldier that did his duty, even if it meant walking through the gates of hell onto a God forsaken battlefield. I admired him for that, and I’ll always miss him.
Gotta love the scale of warships when cannons that were considered amazing for tanks (75 mil) are thought of as medium aa
The largest guns mounted on a tank are like the peashooters on ships
Another fun thought is about armour and penetration: modern tanks have frontal armour and firepower that faaar outclass that of WW2 battleships, at least on paper. You know, effective frontal armour approaching 1 meter equivalent of RHA, and guns that can penetrate such armour. The only difference is, a tank gun can't punch through armour that thick at 30km range xP I really wonder what would happen to a Leopard 2A6 or a T-90MS if they were slapped in the face by an AP salvo from 16'' /50cal guns at that range. Would they bounce off or shatter? That'd be quite the thing to see
@@johnfrancisterne1072 and look how times has changed... Today most deck guns are actually lower caliber than modern tank guns (although typically they are higher velocity weapons, and quite often quick-firing revolver cannons) And modern Tank guns finally reached caliber used on WWII dedtroyers.

While as an American I am happy that the 5"/38cal won overall, the idea of that UK 5.25"/50cal literally sniping Japanese craft out of the skies pleases me immensely.
I’m imagining the multiplayer announcer from Halo making his Headshot cry whenever that gun fires lol
They did not have enough material to expend without getting a result to show the Quartermaster when they wanted another round.
The 5 inch/38 gun was far more workable and a marvel of engineering, however in the early to mid 50s, the 5.25 had more development potential. It became a truly lethal weapon with remote power control and power ramming on Anson, Vanguard and Bellona class Didos

During my first year aboard DD540 ,a Fletcher,I was in charge of 7 motley apes, in the ammo compartment below #5 AA gun. Being the tallest,it was my job to push clips of 40's, up thru a slot above my head. The gunners would grab them and drop them into slots of the guns,where they would automatically fire,as long as the gun Captain,and the Sight Controller each held their firing switch on Fire mode. We saw nothing from inside. One time our ship was missed by 2 bombs, which exploded in the water, missing us by about 5 feet. The concussion blew out our lighting,and blew a couple of control boxes loose from the bulkheads.that caused them to swing by the cables, in the dark, knocking a couple of guys down. Thinking we were hit,I opened the hatch.There was just blue sky filled with AA puffs, and soon the damage control team came and secured the Control boxes. After a year of that GQ station, I was assigned as sight-setter on #AA1 Sight . This was right on the bridge where I could hear some orders, and see the action. Officers previously were assigned to that position. I was FC2C at the time. We were a lucky ship, with the 3rd. or 5th. Fleet, involved with everything starting with Saipan, and ending with 'The Bombs'. We were one happy bunch, and were shocked when we realized we had survived.The Captain celebrated by giving us a straight shot of Bourbon!

Didn’t they basically have the cannon equivalent of a shotgun shell?
@@joshuahadams An incendiary shotgun shell. Basically it was an 18inch time fused shell, that would detonate, hurling out a mass of thermite filaments in a conical blast intended to flat out incinerate anything within the blast zone. To my knowledge, they were never fired in combat and wouldn't have been especially effective if they had, being more of a firework show than an actual weapon
@@weldonwin They were used (google san shiki for more). Though they were sufficiently awful that they were rarely used, as it was difficult or impossible to man the actually useful AA guns while the main battery was being fired.
@@joshuahadams Type 3 incendiary shrapnel, produced all the way down to 8" caliber for cruiser guns. Not terribly effective against all-metal aircraft, even if you do time the fuse correctly.
Longest range and largest rate of mass thrown downrange does indeed seem to have been the IJN 46 cm guns firing Sanshiki Model 13 “Common Type 3” antiaircraft incendiary (IS) rounds. The USN Air Action Reports for the Battle of the East China Sea indicate that 11 of the 16 squadrons making attacks on Yamato on 6 April 1945 came under main battery fire. This involved both air-burst shells and shells fired into the water in front of attacking torpedo bombers. Main battery AA fire extended out to ten miles. No indication of any USN aircraft harmed by main battery fire. As the purpose of the Ten Go attack was to beach the battleship and shoot up the invasion fleet, pointlessly expending so much ammo swatting at gnats seems puzzling. During the actions off Guadalcanal the IJN evidently used Type 3 IS projectiles for both shore bombardment and shipping attack; USS Quincy apparently came under fire from IS shells (Hornfischer, 2011, "Neptune's Inferno" p.71). There are stories of unburnt “rubber thermite” filled sub-munitions "littering the decks everywhere" after such attacks. As recounted by Hornfischer (p.327) sailors on the USS San Fransisco found it a bad idea to put one in your hip pocket as a souvenir as they were sometime still active and couldn't be put out with water. Interesting concept, using sub munitions during Naval engagements: Maybe Drach could do a story on this?
My grandfather, pom pom gunner on ships including HMS Manchester, would approve.
You can't have a reasonable comparison of antiaircraft guns without mentioning ammunition. Specifically the proximity fuse, which was a game changer.
While true, I believe he deliberately did not take technology such as proximity fuses and radar targeting into account. This made the comparison between guns of different nations fair, because otherwise the nation with a worse gun, yet better technology in other respects would win every category.
@@MoeZiilla A gun, any gun, is a system. Ammunition is part of that system. You can't make a comparison by saying "oh, the firing mechanism on this one was marginally better than on that one" while ignoring that one had exponentially more effective ammunition is a fool's errand.
Before the U.S. entered World War Two, my grandfather worked as an iron miner in Lyon Mountain NY for a while. Later on, he hauled breach blocks for 90mm AA guns from a manufacturer that used Lyon Mountain iron to Chelmsford MA. When he was drafted into the army, he served as an anti-aircraft gunner... using 90mm guns.
So, there's a chance that he actually dug up some of the material for his gun.
That’s extremely sad interesting
My Dad was fire watching in H&W during the shipyard blitz on Belfast.He decided the safest place was beside a navy vessel which was putting up a barrage. He found that quite dangerous from flying cartridge cases which he nabbed to store his nails they were roughly1 1/2 wide and 4" long.I played with them as a child. Unfortunately I no longer have them .
1.5" wide would make them 37mm or 40mm calibre, which sounds about right.

There’s the Colt 1911, the US Marines still use it, and it was, like the M2, designed by John Browning.
@@Kromaatikse pretty effective against the Germans and Italians too. Indeed, the transition to cannon wouldn't come for another decade or so, helped by the unreliability of early US 20 mm cannon designs and the lack of heavy bombers to shoot at.
It's odd the Japanese held on to the 25mm. Their aircraft had several good cannon designs around that size that were essentially scaled up Browning designs. They also almost certainly had captured examples of the Russian 23mm, another excellent light AAA autocannon design.
I wish the actual statistics were provided, i.e., "399 rounds per minute, rather than pretty good or average, etc. The range is "2300 meters instead of somewhat pretty fair, but not as good as the Swiss 67 mm, which is slightly less but O.K.ish, etc., etc." More objective, less subjective, or opinion-only. Love the channel, though.
An hour long discussion of AAA fire control advances in WW2 would be interesting. Radar and proximity fuses. Also, how effective were fuse setting devices!
"Two barrels good! Four barrels better!"
After the war the Soviets went through a phase where they mounted quad 45mm and 57mm on their ships.
That sounds beautiful
"Two barrels good! Four barrels better!" Eight barrels best!

Wasnt there a project for a 2×2 turret that was basically a giant bofors?
I'm sure they wanted to develop quad 5.1 inch turrets too. I can't begin to imagine how badly that would train and fire without remote power control and power ramming (only post war viable) given how atrocious the triple 4 inch gun was as a purely anti surface weapon
Not for drach maybe but an anti tank weapon version of this video would be stellar.

35mm go *BRRRRTT*
My grandfather was a yeoman and a sweeper for the 40mm bofors on a US destroyer tender back in 1949 through 1952
Drachinifel: The most common anti aircraft guns.
Me: Do you mean the bofors guns?
Drachinifel: No the other guns too.
Often wondered how the US 1.1 inch ‘Chicago Piano’ (replaced as soon as possible when its shortcomings became apparent) compared with the Japanese 25mm (a gun which continued to provide unsatisfactory results into 1945). Thank you for providing your detailed analysis and ranking.
To be honest, I'd love to see whatever spreadsheet you used to analyze all of this.
The major consideration for the longer-ranged weapons particularly is the capability of the fire-control systems to which these weapons are attached. Many of the small weapons listed are "one-man/one-vote" where, with minimal supervision, each gun is fired by its one or two-man crew at whatever they personally think is the best target within their arc of fire and range. The advent of small "angle-rate" calculators built into their guns later in WWII in many US 20mm mounts, at least, gave some better chance of hitting by using a fixed average expected range and the rate that the gun was being moved in elevation and bearing to provide the other bits of data for calculating a lead angle (in both bearing and elevation) to increase accuracy. Most larger weapons had eventually separate directors added that could control its dedicated gun mount or, depending on the system design, several nearby mounts, and these greatly added to their effectiveness, particularly systems designed for director control from the start (US Navy 5"/38 gun on its several mount variants). When radar came into the picture, weapons that could use it got much better, since range, in particular was now extremely accurate, though the narrow radar beam-width to get good angular position and rate tracking took longer to perfect. When "2nd order" rate tracking became the norm for aiming calculations, where, once a target was being tracked properly, its internal "virtual" target inside the calculator's mathematical "motion space" was set to allow the target to coast at its last good rates, things got much better for AA tracking systems. Now, only if the target began to diverge from its expected track due to it changing speed and/or maneuvering, did the calculator need to adjust this "coasting" internal virtual target. This made updates to keep up with a target MUCH faster and made it more difficult for a target to "break lock" even with chaff and jamming unless it did violent maneuvers while hidden, since if it came back into the radar's view anywhere near its old expected position, the radar, which was moving its dish as if it was still tracking the target anyway, would just lock back on as if nothing had happened. Older radar systems with simpler calculations could not do that very well. Note that not only had the calculators have to be accurate, but fast enough to keep up with fast-moving, maneuvering aircraft to get enough lead to hit the target (aiming where it is now is obviously not viable), but the speed of transmitting the information from the tracking systems (optical and/or radar) to the calculators and their fast transmission of their orders to the weapon mounts had to be acceptable. "Follow-the-pointer" systems where the information, usually the orders from the calculator to the weapon mounts due to their weight, had to go through a person who looked at a dial reading from the calculator and did his best to keep up with it using his hand and foot controls, was fast enough for firing against slow surface targets (though accurate "eyeball" matching of the orders dials was not always the best) but it got more and more ineffective at longer ranges against high-speed aircraft, since even a small error would mean that the shell being fired would diverge from the aim point too far to be reliable, even when the VT (proximity) fuzes were adopted, though they greatly helped, of course. Complete Remote Power Control, where the calculator could in Remote/Director Control take over the gun mount aiming, with the human there only for backup or special things like shore bombardment, was the rule in the US Navy at the end of WWII, with Germany and, to a lesser extent, Britain also having this RPC capability at least in some gun systems, which eventually completely replaced humans in gun mounts, even small mounts, after WWII. Rating complete fire-control systems (weapon, sensor, calculator, location on the ship) is not a simple thing, though, even if you precisely know the targets it was made to destroy.
Quick suggestion, editing the comment and chopping it into paragraphs very much helps people read through it without loosing their place
@@marcusborderlands6177 I do that in some cases. Depends on how much effort I take to do a comment. You are correct that I should do it more often. Thanks.
One hour of pure, unadulterated, detailed and (ostensibly) explosive content! Drach, this might sound silly but.... you couldn’t imagine how much I needed this. Just something to listen to and enjoy whilst disregarding the cares of the world. Thank you sir.
I was hoping you might mention the 18.1 inch sankhiki anti-aircraft shells fired by the Yamato / Musashi battleships . Possibly the heaviest AA rounds , and "dual purpose" guns ever to see service . Both spectacular to witness , and spectacularly ineffective . Almost worth an episode in themselves , although I don't know if much reliable data still exists for them .

54:16 - "It's got a twelve-and-a-half-thousand-meters antiaircraft ceiling, which puts it quite a way up there" ...both figuratively _and_ literally.
I'd love to hear more about the less-common AA guns like the Japanese merchant marine short AA/ASW guns and those of the minor navies!
This was a very informative video. However, if I can state a recommendation, it would be this in assessments that are rather heavy on the technical side could use a little bit of numbers on the screen to keep track of things. On many occassions I found myself rewinding to a previous gun in order to pick up a number to compare it to the next gun in line. A few numbers and names on screen would help _immensely_
Teacher: Did everyone do their AA installation homework?
US: the top student who grinded their soul into their homework
UK: not that much but did it pretty well

Not sure the US was so much the top student, as it was the student who was surprised to find his favorite hobby was actually a graded activity. He just loved guns, he didn't know it was going to be graded.
Lol nice comment
Great! Another excellent video topic by the Drach-master! Always wanted an in-depth discussion about the rapid advancement of fire-control and anti-aircraft weapons and tactics!
I’m glad to here you rated the bolfars at the top of its list, my Grandfather was on a twin bolfars on board a tanker/ freighter in the South Pacific, after refueling a destroyer at the battle of Guadalcanal, the destroyer peeled off running away, his gun battery got a kill on a kamikaze, that turned at split the bow of the destroyer wide open like a banana, if he was still alive, he’d agree with your rating of the bolfars

Great video as usual. The amount of work you put in is stunning, really. Id really love to see a video about the peculiar and weird AA weapons, such as the AA shells of the yamato etc etc.
This video cant help but remind me of a Kancole story I read which had the following line "Bofers is the new black" because let's face it damn near everyone who could dressed their ships in Bofors is some cases the ships' crews did it, never mind where they found it, it's here now.
In medium category shell weight might be over empahasized. These are all 37 or 40mm HE rounds fired directly at the enemy, thus practically any hit would be fatal to the aircraft these would be usually firing at. The shell weight does affect muzzle velocity and range, but those are already separate categories.
I should also note the German M42 and M43 are far lighter weapon systems than those higher in the category. Perhaps not enough to make a significant difference on most naval mounts, but M43 was also used on land. Both towed mounts and mounts on armored vehicles were relatively simple for it thanks to the low weight.
I'm constantly amazed at the fact you can find all these old pics? and the fact these old pics were taken ...and survived!!!
One point of note that may be a neutralizing effect is barrel life. The Italian 20mm may have been elevated from its low ranking to a respectable ranking, simply because it maintains its accuracy longer. The high rate of fire guns and cannons with shot out throats and rifling would be lowered in ranking if they couldn’t hit the broadside of a barn.
Masterful work as always.
Two thoughts, there was a 3 inch gun mounted on Royal Navy A-I destroyers in lieu of the aft torpedo tubes and on V/W long range escort conversions. I guess it belongs in the bottom category.
I think the Italian 100mm deserves its own category, I've read it was "deemed unsuitable for aimed fire" meaning used to fire a barrage and hope you maybe hit something. They were replacing them with 37mm guns because 37s actually could hit something....
was missing all the stats you were running through for the guns, would have loved it if you put those on screen as well! Other than that an excellent video as usual!

A gun wich menaged to shoot down 7 planes on a Spica class? (and many other planes on many other ships)
@@dariomasi9 Exception that proves the rule. Just because it shot down some planes doesn't mean it was a good gun - the 1.1" Chicago Piano managed to shoot down some planes too, but it was awful.
@@TexasSpectre
Thats not what i was saying...
Just that it wasnt such an awful weapon as both Drach and many commenters say it is.
It was better than the japanese 25mm despite what Drach said (he tried to sugarcoat how awful it was by not dweling into just how awful the mounting requirment was)
It was "bad" when compared to the oerlikon and late war german 20mm, it was still not the worst gun of its caliber nor other light guns, dont even get why it was compared to medium caliber guns since the requirments are very different.
The breda 20mm dindt just "shoot down some planes" it was a clear threat to any plane it its range unlike the 25mm and the Piano gun, i can count around 30 ish confimed planes shot down by it alone, without the help of medium caliber weapons, wich is quite a lot for a gun of its size.
@@dariomasi9 I don't know why people take Drach as any sort of authority, he just repeats old bullshit from other sources and packages it up for videogame-obsessed idiots (see: the idea of 'scoring' AA guns by a bunch of arbitrary numbers instead of actual historical data)
Another winner!! Thank you Drach!
I wanted to say that everyone who loves these videos PLEASE become a Drachinifel Patreon! This guy does such a great job and deserves your contribution!
Never heard of the Japanese anti-sub round. Can you provide any details as to how it worked and how effective was it?
Probably not as effective at killing American subs as their own torpedoes. Thanks BuORD.
Hey Drach, did some digging around and found a story in Air Force News (official US Government site) that claims the cost per round of 40mm AA rounds was $8 in 1940’s dollars. That figure is for training rounds though.
I really like the in depth, detail oriented style of your videos
Have you done an episode on the proximity fused shells? Some say that is what made the 5"/38 the superior AA weapon of the war.
I knew the 5"- 38 was going to win, I was waiting for him to talk about the radar proximity fuse as the main reason why. He never did and that made me sad. :(
It's quite funny that of all the navies in the world, Polish was one of the first to see the light and adopt the Bofors
Makes sense to me. Polish history is like a bad porno, every opportunity the neighbours fuck them. Maximum firepower in a transportable platform? They'd love it.
Is that why they charged the Bismarck? Trying to get the 40mm in range. Ha
@@cmikles1 funny as it may sound, that was actually leased british N-class destroyer carrying pom-poms.
If my memory serves me, the US submarine force took a liking to the 5" 25 cal. for deck mounted weapons. Dunno how much water proofing it required but it beat the schnizzle out of the older 3" that created underwater drag than defense on a boat.
I believe the "wet mount" for submarine deck guns required the optics to be in a removable module, so they were not subject to submerged pressure. The gun barrel received a muzzle plug to complement the breech - probably didn't keep seawater out entirely, but would have reduced the extent to which internal coatings were washed away and marine growths built up while submerged.
The deck guns were not for defensive purposes, but rather for engaging targets that were too small to be worth a torpedo, or for finishing off a damaged target. The 3-inch gun could do that, but took a long time and a lot of ammo to do it. The 4-inch gun was significantly better. Some boats received 5-inch or even 6-inch guns, which could be considered overkill.
Then there's the British M-class Submarines, 3 subs where made and they mount single barrel 12" gun as deck guns like the French Surcouf 8" gun submarine

The only thing I wish you included was the yards in range, as I have no idea hoe far away a WWII navel battle is as now a days a missile can go destroy its target over the horizon and you dont have to worry about powder magazines exploding.
3:21 That's an amazing photo. 4 torpedo tracks, 2 intersecting the carrier.
Hey Drach, good video! If you look there’s some footage here on YT of 5”/38 twin mounts in action during WW2 on an Essex-class carrier. To quote a certain RUclipsr, they put a hilarious amount of shells in the air. Looked quite devastating really, which begs the question: “Does a kamikaze pilot REALLY care much about the status of his underwear?”
Just about to start overdue college assignments..... Guess they can wait now :/
If you walked into an anti-aircraft showroom, you would buy 5"/38. It's lovely. It's elegant. It's beautiful. In the world of heavy AA, it is the Saville Row suit, the Rolls Royce Corniche, the Chateau Lafitte 1945. It is the heavy Anti-aircraft gun Harrods would sell. What more can I say?
Throw in a pallet of VT fuses to go.
Especially with the Mark 37 fire control system installed!
@@tcpratt1660 moreso using VT fuze, controlled by Mk 51
I am not sure if the Oerlikon 20mm is better than the C/38 by that big of a margin. Both had a max rate of fire of 450 rpm, with the difference in practical rpm being the magazine size. Since light AA will not be shooting all the time during an engagement, I think there will be time for loaders to change out magazines. Larger magazine does carry an advantage, but I don’t think it is as much as the practical rate of fire reflects.
Aside from that, Oerikom 20mm had a muzzle velocity of 820 m/s and range of about 0.9-1.0 km against low flying aircraft, while the C/38 had a muzzle velocity of 900 m/s, very high among light AA, and a range of 2.2 km against aircraft, much longer than the Oerlikon.
