The overlay of animation on top of real footage is really cool to see. It helps give perspective of what parts are moving at what speed in real time. Great video!
The small puff of smoke after the round leaves the muzzle is from the air blast that is ported into the breach as the block is opened to avoid the mount housing and lower assembly from filling with propellant smoke.
I love using this video to show my civilian mates a bit of my job. As a 5 inch maintainer, this video is pretty spot on as a quick explanation, without going too much into detail. I love working on this gun and have been lucky enough to have the chance to fire it locally during a GFT.
for hours........that’s nice of you. i work at an Artillerie Ammunition Plant and i smells it all days .(also bad for health) we made fuze, explosive filling, make increment charge and propellant bag for both mortar and artillery. some day we burn expired explosive, fuze propellant charge, all my uniform smell of TNT for week, and air quality is just shit. we wear mask for week (before virus, after virus is mask all day) but worsts of all is a guy at explosive smelting plants. those guys work with raw chemicals and explosives.
So did you guys discarde the empty brass? or did you collect it and return to the munitions maker? Also what targets are most likely for this gun? Can they take on other big warships (though I know that no one has battleships any more :( )
Back in the 1970's the MK45 I worked on was twice as fast as this. It had two loading drumbs in the Magazine, (two decks below the mount), and a double hoists taking the rounds to a twin carrier on the deck below the mount. The twin carrier would rotate the rounds to the guns orientation, where they were transfered up to the cradle in the mount which brought the rounds from vertical to horizontal. Once the rounds were horizontal the cradle would transfer it's round to the loading tray, to set any timed fuses, then to the ramming tray where it was rammed into the breach and fired. As the first round fired and recoiled, the breach would drop, the empty shell would be pulled from the breach into an ejector tray below the breach, where it was ejected under the barrell when the next round fired. We could fire 55 rounds per min, (and often did, as shore support in Viet Nam). This configuration required a Gunner's Mate in the mount and another at a control panel in the carrier room. It also required at least 6-8 men in the magazine to keep drumbs full. The one shown in the representation here looks like it may require less manpower, but I would think double the firing speed is well worth the cost of a couple extra GM's.
I’d love to see one of these animations on the Des Moines class 8”/55 caliber guns. If I’m not mistaken they’re still the largest self loading artillery pieces ever made.
Unless you mean autoloading, that's dead wrong. The largest self loading naval artillery would be the 18.1 inch gun of the Yamato, who did not require a single person for it's reload process.
XD you ever see the video of I think it's a Russian tank dispensing the casings behind it and there's infantry staying behind the tank and the casings keep nearly hitting them. It's kinda funny to watch.
Very informative video, I look forward to purchasing my own MK-45 5-inch Gun. A few 5 inch shells will teach my neighbor not to let his dog out on my lawn.
i once heard a military quote "amateurs talk about tactics, professionals talk about logistics" i feel like this is the kind of stuff the professionals talk about
I worked on this system, the Mk45 Mod0 for 6 years and taught it at Great Lakes for 3 years, '81-84. This gives a good overview of how the system works.
@@CrackedCandy I don't quite get it, size or caliber but calibers went from 20mm all the way to 80mm. Of course there's the measurement Anglo in inches, from 5 to 15 & more, different ships sometime had a combo, pounders goes from 12 to 32. WW2 style went generally from 8 inch- 55. Some experimentation have been done with 18.1 inch. US settled for the 5/38 from ww2 & on.
What this video does not explain: how the casing and the shell are getting transported upwards. I mean: what drives them forward? And it is also unclear how the empty casings are getting out of the chamber?
the empty casings are launched out by an extractor, basically a rod that catches the "lip" or rim of the propellant casing. not sure how similar it is to ground based artillery, but alot of extractors are cocked by the recoil of the gun to give it the necessary force to unstick the casings from the chamber.
@@MUJUNKY thank you. That is the same principle as for semiautomatic guns. But it was not shown here in this animation. And it is still unclear how the casings are ejected from the turret and before that how the ammunition gets elevated to the chamber.
@@ralfhtg1056 the ammo elevator is essentially a chain driven platform, it has a small floor or step attached, loads the new projectile and propellant into the drum, then the little platform folds over and goes back down. Not the best explanation, just drawing from memory of a video I saw. As for the mechanism that throws the casing out of the turret, I have no idea. You may try to find a video like "inside the turret Arleigh Burke" the TV show The Last Ship had some pretty cool inside the turret clips of the gun system working that may be what you're looking for.
It's even cooler watching the internal components work down below. The animation doesn't do it justice. One time we got a round stuck in the barrel (which is semi-common) and had to blast it out with a clearing charge. In local control, there's no automatic stabilization, so as the ship rolled, we fired into the water about a hundred yards off the port side. I was walking forward on the weather deck at the time. Scared the shit out of me lol
@@christofincognito4530 The projectiles have a soft copper ring around the outside called a bourrelet or rotating band. When the round is rammed into the gun, the lands of the rifling dig into the copper to form a tight seal. You can't get that round back out without firing it. Or at least not easily. So you use a smaller size powder can called a clearing charge to get it out.
So what good is it to fire into the water? Couldn’t they have figured out how to compensate for that? Also, if a round got stuck wouldn’t that destroy the bore?
Eh, okay animations I guess. Would have been better if it included how the ammunition hoist worked and the rammer and the way the main magazine gets ammo to the hoist. But lots of boom boom so, it's pretty good.
@@LEEGOOVER9901 two parts of hoist: upper hoist, lower hoist, both powered by hydraulics. lower hoist is a chain system with two tubes like shown, one goes up on goes down. Upper hoist only goes up. when the drum rotates the a round will sit on the upper hoist, the shell goes up into the cradle and the cradle locks the shell and swing to gun elevation axis. A rammer powered by hydraulics which sits in the slide, ram the shell and the breechlock is dropped. after the cradle is lowered the round is fired and the slide recoils. Then a case tray lowers and the breech is opened, the extractor pulls back the shell and it sits on the case tray and it is ejected as shown above, meanwhile the cradle is lowered to receive another round.
Question, why would they not make one of thoes in a larger callibler that 127mm? why not a 355mm or a 406mm? ( on a bigger ship of course ) does it have something to do with barrel tolerances or logistics issues?
There is no longer a need for rounds larger than 5 inch 127mm anymore. Missiles and aircraft smart bombs can do a better job with more precision. The USN had autoloading 8 inch guns in the 1950's on the Uss Salem.
Back when they had an actual GM school at Great Lakes, there was a fully functioning Mk-45 mount. That was a truly beautiful building, I can't believe they demolished it.
@@FormerVicePresidentDickVeiny Sometime around 2008, I think. It was sitting empty for years. Thing was like 400k square feet, cost a lot just to maintain it empty.
@@tstahler5420 I was on board Great Lakes in 2000 and 2001 when I was in the Sea Cadets in high school and even had a class in the GM building. I know the building was still being used then.
@@FormerVicePresidentDickVeiny In '86, I attended GM phase 1, then rocked out of BEE school. I have never been soo happy to fail at something and depart a location in my life! I will never, willingly return to Illinois in my lifetime. 😂
@@tstahler5420 ha! Good one. I had my heart set on becoming a GM out of high school, but when the navy recruiter told me that rate wasn't open for another year, I signed up infantry Marines. Haha big woops!
I am speculating, but since the turret is rotating, the ejecting shell casing could possibly end up striking something that should not be struck, like the ship's superstructure. Since the barrel is pointed in the direction of what is to be destroyed, tossing the steel casing in its direction is the lesser of the evils. Everyone aboard is aware at a glance, not that you see anyone out for a stroll during battle stations. A dedicated storage for the empty casings adds another level of complexity, in terms of added cost, the need for more space, & the possibility of a malfunction causing the gun to cease firing.
The older Mk42 rate of fire was 40 RPM and had dual loading drums and dual sided loaders. The gun barrel was heavier. 3 of these guns with 1000-1200 magazines each like the old Forest Sherman I was on could put out 120 RPM. Of course you went into a hot gun situation pretty quick which was dangerous but you get the idea. Guns are no longer the Main Battery on a ship, hence the single and slower MK45
And they are mainly used for ground support and firing warning shots, so a reliable and light design is more important. The Mk42 where AFAIK downrated to 28 rounds per minute in the late 1960's and weighted about 60 tons per turret, while the Mk45/54 weights in around 25 tons with about 20 rounds per minute. The Bofors 120mm Model 1950 did 40-45 rounds per minute BTW, with destroyers having 4 or 6 guns each (in twin turrets), for a total of 160 to 270 rounds per minute. There was also later Bofors 120mm designs, designed to fire 75-80 rounds per minute per barrel, but they didn't see much use. In the US there was work on the 5"Mk Mark 65/66 as a alternative to the Mark 45, firing 48 rounds per minute per barrel with the Mark 65 having a single barrel and the Mark 66 two.
What happened when the ammunition inventory got low? I've seen footage taken from spotter planes in the Vietnam war showing multiple square miles of cratered land after being shelled by a battleship and it looks to me like an inconceivable amount of shells. Was it common to be resupplied with ammunition at sea or did the ships generally have to sail to a port for resupply? The scale of it all is very amazing to me: the guns, the boats, the logistics, and the engineering.
@@steventhehistorian Either by Underway replenishment or by heading to a port if it was close enough. Unrep in those days was mostly ship to ship. Vertical Replenishment is the prmary means at present.
The original system first used on the USS Salem's 3"/70 guns in the 1940s used a single rammer to do two functions. This system split the job between two rammers. Much simpler and more straightforward.
@@ghost307 or for people who realize it make more sense to have a robot which is faster, can't drop shit, takes up less space and can be ready to load the gun instantly without having to station someone in the gun makes more sense
It has almost similiar to the T-72 tank autoloading process with rotating magazines below the turret and ejecting the spent casings from the top of the turret
Is the projectile crimped to the charge base? If not, how does one unload the projectile when a cease fire is ordered and a round is loaded? I see the base is lipped for extraction but what about the projectile? Excellent animation by the way. Very well done!
It does not load then wait to fire. The barrel stays empty until the fire signal then the round loads and instantly fires. Keeps rounds from getting heat soaked AND there's air blowing down the barrel to clear fumes out of the turret and slightly cool the barrel. Watch the firing video again and see the small second puff of smoke after the first firing cloud. Also, these rounds are programmable so they can be switched out for a different one or programed just before inserting and firing
@@bobjoatmon1993 Thank you for the detailed explanation. Makes sense. Didn't notice the second puff of smoke the first time I watched it, but did now. Thanks again!
Is the shell really just sat on top of the propellant charge like that? Not a single piece? If it's separate then can different types of rounds be fired?
How is the "round propelled through the system is there some kind of magnetic system or just like rammer and elevators and how is the case ejected it is unclear in the animation it looks like they are just sucked through
@@concernedcivilianwilliam3396 Good to hear. Well if you have replicate your enemy's weapon system, but your enemy has a better weapon system than yours then start copying it to improve your current weapon system as well. Right?
@@jhonfloibelmiculob6581 yes, I guess you are right. But don’t worry about too much I reckon. As much as I like warship guns, they are not that useful in actual combat except bullying small ships and warning shots. This is my conception at least, somebody plz correct me if I’m wrong.
mechanical firing mechanisms are easy to replicate, the real secrets are the targeting computer/system, the propellant for the munition and the munition itself, really, modern ballistics theories have been around for over 100 years, this gun is mechanically simple to emulate
Excelente sistema de recarga, seguro control remoto de tiro, tiempo justo para actualizar el colimador entre tiro y tiro, sin riesgo para un operador en la torreta, un buen calibre para encamisar con tungsteno que es bastante escaso sin renunciar capacidad perforante - explosiva.
As an ex GM on the mark 45 mod 1 (5" 54 cal) rate of fire was 16 to 20 rounds per minute...depending on elevation. This shown is the forward gun mount...I was an operator... a pain in the ass to bleed the air out. Mod 2 was supposed to be self bleeding...was out before that came out. @5:45 mod 1 outer shell. Off on the animation with the recoil, ejection tray and cradle animations.
As a current serving Gunbuster in the Royal Australian Navy I get ya with the bleeding maintenance. I just finished my mod 4 course done with GM's in San Diego a few months ago. You guys have some pretty switched on GM's and it was heaps of fun working and learning with the USN.
127mm is 5 inch. I never thought about it. Now the soviet M-30, D-30 and self propelled 122mm Grozdika(spelling?) Makes much more sense. I thought it was an oddball caliber that nobody else used. Thanks for illuminating this for me. Excellent animations.

The small puff of smoke after the round leaves the muzzle is from the air blast that is ported into the breach as the block is opened to avoid the mount housing and lower assembly from filling with propellant smoke.
While the ventilation is nice, it's actual primary use is to clear any un-burnt powder from the barrel, to prevent an unexpected flash.
Explains the lack of a gas recuperator. Not needed, vs in a tank or howitzer turret.

the part where the real life footage is combined with the animation is amazing!
Love the sound of the empty casings rolling on the deck.
I'm sure the boatswains mates don't 😂
@@jedisaki730 Lol.
They would sound much better if they were the old school brass versions!
what's sucking the artillery round into the loading mechanical arm? Is there are also a hydraulic rammer that pushes it to the barrel holding point?
Back when they had an actual GM school at Great Lakes, there was a fully functioning Mk-45 mount. That was a truly beautiful building, I can't believe they demolished it.
All green glass. Very cool. Didn't know they tore it down.
@@FormerVicePresidentDickVeiny Sometime around 2008, I think. It was sitting empty for years. Thing was like 400k square feet, cost a lot just to maintain it empty.
@@tstahler5420 I was on board Great Lakes in 2000 and 2001 when I was in the Sea Cadets in high school and even had a class in the GM building.
I know the building was still being used then.
@@FormerVicePresidentDickVeiny In '86, I attended GM phase 1, then rocked out of BEE school. I have never been soo happy to fail at something and depart a location in my life! I will never, willingly return to Illinois in my lifetime. 😂
@@tstahler5420 ha! Good one. I had my heart set on becoming a GM out of high school, but when the navy recruiter told me that rate wasn't open for another year, I signed up infantry Marines. Haha big woops!
Why the spent casing/shell is ejected forward (unto deck)? Why not sideward or backward? Or directly into dump storage?
I am speculating, but since the turret is rotating, the ejecting shell casing could possibly end up striking something that should not be struck, like the ship's superstructure. Since the barrel is pointed in the direction of what is to be destroyed, tossing the steel casing in its direction is the lesser of the evils. Everyone aboard is aware at a glance, not that you see anyone out for a stroll during battle stations. A dedicated storage for the empty casings adds another level of complexity, in terms of added cost, the need for more space, & the possibility of a malfunction causing the gun to cease firing.
@@Urbicide ah yes, that's very makes sense. You don't want to be anywhere near the barrel of big gun is pointing toward.
確か、海自の新型護衛艦もこのタイプの主砲だったはず、装填と薬莢の排出の構造がこうなっていたのか。
あたご型以降は全てこれですかねえ
タイプというか、MK45だよw
というか日本は実質これしか無いやん、乙女はあれやし....ｗ
昔の艦砲みたいに直下の弾薬庫ごと回ってるのかと思ってたけど、揚弾する部分を軸にして砲塔だけ回してるのか。
勉強になるなぁ。
軽量化のためですかね。弾薬庫部分を回さなきゃその分回る部分が軽くなりますし。そうすれば旋回も早くなるので。
艦載砲の中をCGで表してくれんのほんとわかりやすい
The older Mk42 rate of fire was 40 RPM and had dual loading drums and dual sided loaders. The gun barrel was heavier. 3 of these guns with 1000-1200 magazines each like the old Forest Sherman I was on could put out 120 RPM. Of course you went into a hot gun situation pretty quick which was dangerous but you get the idea. Guns are no longer the Main Battery on a ship, hence the single and slower MK45
And they are mainly used for ground support and firing warning shots, so a reliable and light design is more important. The Mk42 where AFAIK downrated to 28 rounds per minute in the late 1960's and weighted about 60 tons per turret, while the Mk45/54 weights in around 25 tons with about 20 rounds per minute. The Bofors 120mm Model 1950 did 40-45 rounds per minute BTW, with destroyers having 4 or 6 guns each (in twin turrets), for a total of 160 to 270 rounds per minute. There was also later Bofors 120mm designs, designed to fire 75-80 rounds per minute per barrel, but they didn't see much use. In the US there was work on the 5"Mk Mark 65/66 as a alternative to the Mark 45, firing 48 rounds per minute per barrel with the Mark 65 having a single barrel and the Mark 66 two.
What happened when the ammunition inventory got low? I've seen footage taken from spotter planes in the Vietnam war showing multiple square miles of cratered land after being shelled by a battleship and it looks to me like an inconceivable amount of shells. Was it common to be resupplied with ammunition at sea or did the ships generally have to sail to a port for resupply? The scale of it all is very amazing to me: the guns, the boats, the logistics, and the engineering.
@@steventhehistorian Either by Underway replenishment or by heading to a port if it was close enough. Unrep in those days was mostly ship to ship. Vertical Replenishment is the prmary means at present.
Much improved over the Rube Goldberg mechanisms of the late 1940s.
How is that ?
It is definitely designed for people who are too lazy to load the guy.
The original system first used on the USS Salem's 3"/70 guns in the 1940s used a single rammer to do two functions. This system split the job between two rammers. Much simpler and more straightforward.
Also took the gunner out of the turret.
@@ghost307 or for people who realize it make more sense to have a robot which is faster, can't drop shit, takes up less space and can be ready to load the gun instantly without having to station someone in the gun makes more sense
Totally amazing graphics! Very detailed! Extremely understandable! Good work guys and/or girls!!
6:21 10 point dive for that shell casing
Haha nice catch
Was pretty cool to see the barrel track the target as the ship listed.
This is a beautiful and perfect 3d animation!!
It has almost similiar to the T-72 tank autoloading process with rotating magazines below the turret and ejecting the spent casings from the top of the turret
03:00あたりからずっと見てられる
Why is the bolt of the gun fixed in the animation when firing?
Is the projectile crimped to the charge base? If not, how does one unload the projectile when a cease fire is ordered and a round is loaded? I see the base is lipped for extraction but what about the projectile? Excellent animation by the way. Very well done!
It does not load then wait to fire. The barrel stays empty until the fire signal then the round loads and instantly fires. Keeps rounds from getting heat soaked AND there's air blowing down the barrel to clear fumes out of the turret and slightly cool the barrel. Watch the firing video again and see the small second puff of smoke after the first firing cloud.
Also, these rounds are programmable so they can be switched out for a different one or programed just before inserting and firing
@@bobjoatmon1993 Thank you for the detailed explanation. Makes sense. Didn't notice the second puff of smoke the first time I watched it, but did now. Thanks again!
ちょうど春休みの自由研究でMk-45を自作しようと思ってたので、すっげぇ助かりました（）
5-inch/54 is the correct nomenclature. The shell is 5 inches. The barrel length is 54 times the caliber (5 inches) which makes it 270 inches.
撃った後に煙がタバコみたいに出てくるの好き
くさ
Is the shell really just sat on top of the propellant charge like that? Not a single piece? If it's separate then can different types of rounds be fired?
砲の仰角を維持したまま給弾できるシステムになってるんですね。
なぜ薬莢を放り出すのか常々疑問だったんですけど、確かにこれだと
放り出す方が色々と安全かもしれないですね。
連射サイクルをあげるため、放り出さないとダメなんです。装填と排莢は連動してるので。
So what is a strike down tubes purpose? Missed that along with what makes the shells go up aside from the tube.
To me, the interesting part is how the hoists and rammers work, but that wasn't included in the animation.

How is the "round propelled through the system is there some kind of magnetic system or just like rammer and elevators and how is the case ejected it is unclear in the animation it looks like they are just sucked through
China: Thank you uploader. We're gonna start copying to improve our current naval gun system.
Plz, as if they haven't got a copy of complete thing already, lol. But yeah, I get your point.
@@concernedcivilianwilliam3396 Good to hear. Well if you have replicate your enemy's weapon system, but your enemy has a better weapon system than yours then start copying it to improve your current weapon system as well. Right?
@@jhonfloibelmiculob6581 yes, I guess you are right. But don’t worry about too much I reckon. As much as I like warship guns, they are not that useful in actual combat except bullying small ships and warning shots. This is my conception at least, somebody plz correct me if I’m wrong.
@@concernedcivilianwilliam3396 No need to correct you, I also got your point.
mechanical firing mechanisms are easy to replicate, the real secrets are the targeting computer/system, the propellant for the munition and the munition itself, really, modern ballistics theories have been around for over 100 years, this gun is mechanically simple to emulate
Take out the middle man. Pretty darn cool!

Is that ejection Port fails do they have a secondary means to extract it or does the entire gun have to be taken down for maintenance

ローダーへの装填方法と排莢で薬莢が吸って吐かれる仕組みがよくわからないけど
P90みたいなアイデアでおもしろい。
これを見て模倣してKが付くとダメになるパターン。
装填は人力、薬莢は爪で蹴りだされます。
装填はチェーンラマー 排莢は銃と同じでエキストラクターを薬莢のリムに引っかけて排莢してる。
オートローダーの即応弾は20発 それ以外は人力装填
なるほどなるほど。
装填手は毎日50発とか100発の装填練習してるのかな？( ´ω`)
so then whats the strikedown tube for? i did not see any mention of it after labeling it
なるほどわかりいいね！いいわ！スゴいわ！！！
Thanks for the video. This is quite an eye opening .

Excelente sistema de recarga, seguro control remoto de tiro, tiempo justo para actualizar el colimador entre tiro y tiro, sin riesgo para un operador en la torreta, un buen calibre para encamisar con tungsteno que es bastante escaso sin renunciar capacidad perforante - explosiva.
As an ex GM on the mark 45 mod 1 (5" 54 cal) rate of fire was 16 to 20 rounds per minute...depending on elevation. This shown is the forward gun mount...I was an operator... a pain in the ass to bleed the air out. Mod 2 was supposed to be self bleeding...was out before that came out.
@5:45 mod 1 outer shell.
Off on the animation with the recoil, ejection tray and cradle animations.
As a current serving Gunbuster in the Royal Australian Navy I get ya with the bleeding maintenance. I just finished my mod 4 course done with GM's in San Diego a few months ago. You guys have some pretty switched on GM's and it was heaps of fun working and learning with the USN.

127mm is 5 inch. I never thought about it. Now the soviet M-30, D-30 and self propelled 122mm Grozdika(spelling?) Makes much more sense. I thought it was an oddball caliber that nobody else used.
Thanks for illuminating this for me.
Excellent animations.

You think they let them keep the shell casing?
