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.

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.

[@platygetzkillz2144]

Where have I seen that profile picture before?

[@ronwolff1507]

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.

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]

why the hell get rounds stuck in the barrel? corrosion? low temperature?

[@billparker244]

@@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.

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.

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

[@oloflarsson7629]

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.

[@steventhehistorian]

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.

[@bobjoatmon1993]

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

これは分かりやすい良い動画をありがとうございます。

Great animation, my respects to navy

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。

[@user-xt5hh1sx4h]

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。

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?

Magneto doing it

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.

[@ralfhtg1056]

@@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 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

i need videos like this in my life.

去年からイベントがほとんど中止になり見に行けないのが残念。

水平線と砲身の角度が変わらない。すごい！
