A 3D animation showing how a Bofors 57 mm Mk3/Mk110 naval gun reload works.
The Bofors 57 mm Mk3/Mk110 is fitted with a two 20-round ready use magazines, two 20-round ammunition cassettes and two 20-round intermediate magazines for a total of 120 rounds.

Brilliant. You can see the Bofors design characteristics back to the WW2 era 40mm Bofors.
Basically the majority of gun uses the same principle since ww2 and onward, there not much new invention since then, many are upgrade and inovation of the existing gun. Like how the bofor in the vidio is the mark 110 from a gun that was developed back in the 1970s.
Well I am gonna be that guy and say sorry now
@@coolyeah2410 the Bofors 40mm which the 57mm is derived from first entered service as a towed medium AA gun in 1938.
@@coolyeah2410 So if the gun and loading mechanism is from ww2 and basically simple mechanics, how come US Navy BUYS them from Swedish Bofors? Albeit there might be a production license and they are produced in US... but still the Licens costs on that.
@@petergrandien1440 Well the bofor guy make it since WWII, so ofc they hold the right to their mechanism
since everything in britain is brilliant, what is the next step up from that? we have brilliant too but it comes later on, we only use it if something is truly brilliant
What a gun the Bofors has turned out to be. First produced for the Swedes in 1930 it has stood the test of time and war to prove itself a superbly brilliant weapon. And its story isn't finished yet!!
Absolutely correct! During the Falklands war/conflict. The RFA LSL Knights of the Round Table. Had two 40mm Bofors In two weapon pits at the bow. 11 Ciels Squadron Royal Engineers. Built stands for twin light machine guns. Recalibered BREN's also of WW2 vintage. For anti aircraft defence. Situated at the galley entrances and on the flight deck.On board the LSL Sir Bedivere. 1 Raiding Squadron Royal Marine Commandos also on board positioned their GPMG's on the gunnels. Amidships. This proved effective. A 1000lb "return to sender" bomb. Hit the ariels, crane and bow before going into the water without exploding. The ship was also credited with shooting down an Argentine Mirage. Most likely the Bofor's did the damage.
Es el AK de la artillería
Well, it's now self actuated and radar guided which makes it a completely different kind of weapon, the actual gun part is the least significant part of the platform.
I love your 3-D animation. As a mechanical engineer, I really appreciate the hard work that you created from scratch.
If you or anyone else is interested in how the United States Sergeant York 40 mm anti aircraft tank of the 1980s way more complex feed system worked, I would love to describe it. It was my first job out of college and it was all done with paper and pencil. The tank could nearly 400 rounds of L70 40 mm rounds. Both HE and proximity fuse. I fully understand why the secretary of defense canceled it since Russia had long range missiles that would’ve taken it out very easily.
You designed the York's feed system? Yes I would love to learn about it, a video of it would be very interesting. I expect getting rounds fed into guns that could elevate was tricky if they used magazines. Am I right in thinking they were not belt linked? That DIVAD program had some interesting entries. I like SPAAGs in general!
this is really a clever innovation over the classic bofors magazine fed system from wwii, you keep the mature system, and replace the part of using manpower to fed the magazine with machine, i like this kind of combining the old and new.
すごくわかりやすいです！
Every home in America needs one.
* has one.😂
As someone who served in the Navy, I got to see that cannon in action during scheduled drills that were conducted to ensure it was seaworthy, as well as simply operating at peak condition. Whenever you were walking anywhere in the ship, and that thing went off, you could feel the vibrations throughout the ship go up your feet. And we all wear heavy steel toed, black leather boots!!
No one cares
@@dmoney8602you typed so you do care you know?
Alright, now, how do those four stacks get distributed to the one breech? That's what I want to see next.
It shows you - automatic feed - also reloads while firing...
Given that the magazines have parallel stacks I would assume each stack squeezes, sequentially, into a single feed and the gun itself has a double feed breach. Would be interesting to have confirmation of it.
@@alloy299 Four into two into on, with selectable gates at each 'branch' The original concept was to have multiple types of ammunition available depending on the target. Current usage is programmable multi-function projectiles that are 'told' what to do as they are fired, so ammo choice is less of a critical need. Except 'dumb' solids for practice/
Star wheel. Look up the 90mm automatic AA gun
@@5678sothourn Hi, could you post a link to the specific gun system to which you refer, please? There are several designs out there, and I am not familiar with this “star wheel” feed mechanism.
Great video!
My dad was on a 40 mm Bofors on Remagen Bridge during WW2.
Should have included the spent shell casing ejection in the animation.
Ack ack gun My Grandad was on them in WW2 . After Dunkirk he was injured so was stationed on the AA guns ..He called them Ack Ack guns . So many stories but he always said it was one of the best jobs he ever had in the War .
Ack Ack was the German 88 mm gun. (Acht acht)
こいつの仕組み前からずっっと気になってたから知れてマジで嬉しいw
Excellent piece of mechanical engineering.
中身、こうなってるんだねぇ（感嘆）
If you look at WW2 Bofors they alternated between 2 stack the sailors loaded, I expect with the ability to select which stack they "stripped" a round from that could likely be the simple change in rotation of the feeder would pick HE from the right, or AA frag from the left. Given the magazines can move too, the ready rounds could be a mix of 10 each of 4 different rounds. so you could have cheap solids and AP in in the mix. a 10 round burst off solids across the bow could probably reloaded with HE/AP depending on the target just threatened. Slick system, and that is what is in the turret, 80 ready rounds full of pain to go down range. Now the modern turret shape makes more sense.
What you're saying is true. Problem is the mentality of the average person has gone substantially downhill. Apparently the more technology that gets put into the Public's hands they become dumb down. Unless they join the armed forces and have someone knock some sense into them.

My bunk used to be right beneath that bad boy, onboard a Gothenburg-class corvette, the firing is not that bad, but the hydraulics are loud af.
Were you in the Swedish Navy ?
リロードがスケベ過ぎる
Great video as always. I wish I could have one for home defence and hunting purposes.
Do you like your prey turned into red mist?
@@senatuspopulusqueromanus2082 Yes
it's so much easier when you can eat them through a straw.
Me too. I recently started using one of these as my CCW and absolutely love it!
Really useful as an anti-government official deterrent!
すっげー！リロードするんだ！
って驚いたらマガジンロードまでするの？！
実質装弾数無限やんか・・・
砲塔内のストックが無くなったら終わりか・・・と思ったら足せるとは。凄い仕組み。
Great video! Thanks. It seems as if the Bofors was the only thing that remotely worked….at all!
Awesome! Thanks for these great animations!!
Brillaint. Light weight. This gun shoots more explosive per min than the 76mm super rapid
Perfect explination. Thank you for uploading.
Genial! Dieses Nachladesystem ist gut durchdacht.
イメージとしては「弾倉」「即応弾薬クリップ」「弾薬クリップ用予備弾」
が上にあってそれ以上必要なら下から上がってくる感じか。
I’m sold, I’ll take two.
I don't suppose you have to reload Bofors like this very often, there can't be many problems you can't solve with 40 rounds of 57mm.
It can one-shot an aircraft, can one-shot or 3-shot a modern vessel, and hit almost 98% of the time depending on the electronics of the platform so...
現代なら大量のミサイル飽和攻撃対策が必須だからなあ
40 of very inmediate use, 120 inside the turret... 240 total on a corvette like that, maybe more? 300, 360?
Drone swarm? It will happen sooner or later
*120 : 3x 40 rounds, a hell of a firepower !
After you cycle 120 rounds through that gun I don't recommend toughing the barrel for a while.
Exactly, not even if it's a water cooled version.
i think water cooling can be easily added, but yeah, after shooting for a while barrel will get deformations and will need replacement.
Nice video and interesting charging system but one thing wasn't shown. Where are the fired casings ejected? This is not shown in the animation.
Great illustration. Thanks
Clever design, unlike in the past no sailor's need to be in danger.
Interesting, I always wondered what was “under the hood” of those. Even more happy our RCN frigates have these!
今までの艦砲と違って砲の下に弾倉部分を用意しなくてよいのは色んな船に使えて良いね。オートメラーラのやつは下の弾倉デカかったからなぁ
ここまでの構造を見ると芸術作品に見えてきますね。
なんて解りやすい動画なんだ！
Very interesting.
Do a video for the 40mm 76mm 127mmm
Thanks.
Muito engenhoso esse carregador. Uma solução brilhante
"Splendid work of art."
interesting thanks. nice models
Very good. Can you have it on concealed carry?
Awesome 🎉🎉
This is smart and terrfying at the same time :O
Works great as long as you definitely only want one kind of ammunition. Although I would guess the 2 sides could be configured separately to get 2 kinds and feed selectively to the gun.
Superb video!
Great Job
Great Video! Hats off!
thats brillaint
they actually have a modernized version of the Bofor 40mm L60 called the Bofors 40mm L70, and if your wondering, they do have a twin barreled CIWS of it called the OTO Melara Dardo.
Sweet! How long does it take to reload all the magazines
No one's gonna comment on that dope beat??
That was so cool.
凄ぇ。でっかいクリップ式みたいな装填を繰り返してるのか。
really thx. always wondered about all cannon's feeding system
Ok, but where do the shell cases go?
Typically, the empties are kicked out under the gun on a chute going forward. In this case there would be a hole in the front of the turret. I suppose there could be a system for collecting the empties in a bin, but it would have to be part of the mount, and from the cutaway view there doesn't appear to be enough room, so they're likely discarded overboard
They roll around on deck.
Uhhh……ooops! LOL
結局、オートメーション化されても給弾方法は、昔のポンポン砲・日本の２５ｍｍ機銃と一緒だったのか！
でも、砲塔内に120発あるのはすごいと思うわ。即応弾がたくさんあっていいね
where does the shell casing go?
ejected out the front onto the deck usually, dont know this specific one.
Brilliant. I love it.
When it runned out of the jalopenos i got sad :(
Then the nice jalopeno hoist came along and I got happy again :)
So frikin awesome!!
Genius!
Nice! Cleared that up for me.
Just subbed i like these stuff
These amazing this 3d video I like this 👌👌👌🤟🤟👍👍👍
nice engineering
I'd like to see real time. Thanks for the video.
missing fuctionnning of atomatic canon , alimentation with 4 vertical mag, and ejection of empty case, ..... but your works is awsome thanks....
Very interesting
I did my conscription on the cv9040 and it has the bofors 40mm as a main gun, but its installed upside down, it can realy do some damage, god damn, fast realiable and accurate
Good im rating 100/1
Range and accuracy?
great animation. congratuations.
Great yet simple explaination video. I like it. Well done
Incredibly smart, 120 rounds on the turret before relosding (and able to reload while firing if needed)
基本は40ｍｍと同じですね～
更に5インチスローファイヤを思い出しました。
即応弾撃ったら間があくのですね。
ボフォースらしい作りだと思います。
３インチスローファイヤですかね？
1術校に１基だけ残ってますね。
給弾手は地獄だったと聞きます。
@@sengoku-ze2rw ５’SFです。
旧あきづき型が現役時代に搭載されていました。
ちなみに３’SFは礼砲として今でも神奈川県横須賀市観音崎で３門現役で活躍しています😅👍
@@Mr333R あ、本当に5インチスローファイヤですか！
装填形式似ているんですね。
３インチスローファイヤとラピッドファイヤを間違えてました。
ラピッドが１術校、スローが観音崎にありますね😅
@@sengoku-ze2rw さん、ほぼ人力です。3’SFは約12キロの装薬と弾丸を後ろから人力で薬室に差し込みます。
３’RFは横から人力で装填します。
５’SFは弾丸約32キロ、装薬が約20キロ（ど忘れ）を人力で横から滑りにそれぞれ乗せて油圧で薬室に装填します。
無茶苦茶体力必要です。
４０mmはマガジンクリップで４発づつ上からこれと同じ様に上から人力で差し込みます。
機構としては40mｍの方が似ています。
@@Mr333R 元自なんでだいたい知ってますが、やはり昔の砲は大変だったようですね。当時の先輩は３inRF経験者でしたが給弾手で泣かされたと聞きました
What is the extraction system, where do spent casings go?

Works well
Awesome awesome awesome!!!!
Amazing
do sailors still get to carry any of the ammunition to be loaded or not anymore
This is totally amazing. I had no Earthly idea those deck guns were so powerful and durable.
This video tells you nothing about either of the two...
@@novacolonel5287 Thumbs down.
57 mm gun isn't that powerful, not when you're shooting at enemy ships that are 10,000 tons!
@@dundonrl Wait.....that gun would utterly destroy the bridge of an enemy ship. The bridge, the CIC.....etc. How about exploding a few shells right over the enemy missile launch tubes?
You have to get within range first! Also, you take out the bridge on a modern destroyer you're still not disabling the ship, it's still capable of fighting. Yes, you take out CIC and it's game over, but I'm not sure that it can penetrate into the CIC on say an Arleigh Burke DDG. It would be interesting to see, but I don't think the US Navy would sacrifice one of it's active duty warships for a test like that!@@rael5469
Thanks! Awesome video!
よく出来てるなぁ・・・
Interesting design. Never would of thought of that.
Very cool I From Brazil.
Engineers are really smart.
A single 5 inch or 4.5 inch shell will do considerably more damage at much longer range to a warship than a trio of 57mm.
Yes but this weapon system isn't intended to do that, for defeating warships you just switch to Anti Ship Missiles, why bother with 57mm shell at all
@@alifr4088 As the British found out in the Falklands conflict, the missile armed type 21 was useless without the 4.5 inch gun
Perfect for home defense
as a crusty old gun dog, I approve.
Right On I always wanted to know
amazing
yep , that looks like it would work flawlessly all the time.
That's all ...nice! - but ...can you reload the secondary "bins" while the gun is firing? ...'cause from the looks of it, this gun has to stop firing and realign the gun at least twice when replenishing rounds? Does the mechanism that allows those "cassettes" to be replenished work also while the gun is firing or does it have to wait until the whole "cycle" is done & all the mags are empty??
Bofors 🤘🏻💪🏻
リロード時に砲身が上を向くのが
雛鳥がエサをねだっているみたいでカワイイ
「この時間はワタシ撃てませんよ」と宣言しているようなものだと思うけど
昔みたいに攻撃機が襲ってくる訳じゃないなら、気にしなくても良いことなのかな？
Excelente arma
great vid
So it need to stop firing and elevated when realoading .
Great video.
Those audio pings are incredibly annoying though.
Now show us how ammo is loaded into the ship's magazine in port :)
