How a Naval Gun Reload Works - Bofors 57 mm Mk3/Mk110

#3danimation #reload #bofors
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.

[@coolyeah2410]

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

[@allynhansen7398]

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!!

[@keithdurose7057]

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.

[@vondertann8218]

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.

[@IAmTheAce5]

Alright, now, how do those four stacks get distributed to the one breech? That's what I want to see next.

[@nunyadambusiness6902]

It shows you - automatic feed - also reloads while firing...

[@alloy299]

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.

[@markbecht1420]

@@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/

Great video! My dad was on a 40 mm Bofors on Remagen Bridge during WW2.

[@watchthe1369]

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.

[@Mr.Robert1]

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. Lt Rob, United States Airforce Retired.

[@bostearns7083]

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!!

Bofors 40 mm was/is the best light anti-aircraft gun of all time. I know them, I was the shooter on them a long time ago.

[@dundonrl]

There's a reason why the military doesn't use guns for AA/AAA any more, incoming missiles and aircraft are much too fast to consistently hit them.

[@SimpleTon294]

@@dundonrl they do, they are used but most navies in the world. Of course they are used alongside a variety of weapon systems like Missiles and CIWS. But they are used and they are used against incoming anti ship missiles. No system can consistently (guarantee to) hit an incoming missile, that's why we they use a layered defence.

[@dundonrl]

@@SimpleTon294 Which modern Navy warships use fully automatic guns (like the 40mm Bofors) for ASCMs? I can't find a single one that isn't a CIWS. I know the US Navy doesn't use them, the non CIWS guns are used against small boat attacks, not for incoming missiles.

[@SimpleTon294]

@@dundonrl the 40mm and 57mm are multi purpose gun systems. "Bofors claims that with 120 ready rounds the system can sufficiently engage 1 to 2 surface targets and 4 sea skimming missiles." It's used by the US navy and many navies around the world to engage missiles. A missile going below the speed of sound is not a extreme challenge for the borfors with 3P ammuition. That being said, faster missiles require multible systems to disengage it or destroy it (hard kill and soft kill)

[@dundonrl]

@@SimpleTon294 Would you want to be on a warship that has a maximum effective range for incoming missiles of 6.2 miles? (the 57 mm is 9300 yards/5.28 miles or the RIM-116 of 10,900 yards/6.2 miles on an incoming warhead that's moving Mach 3 (for the Asif/Khalij Fars)?

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.

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.

[@pistonar]

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

Anyone know what the short term rate of fire (e.g. the first 20 rounds) vs long term (e.g. until the ship runs out) is? What limits the long term rate; heat or being secured to load from the hoists?

[@jamcam2760]

Sure beats manually loading magazines like you see in films from WWII in the Pacific.

[@TheAttacker732]

Each have their advantages. The manual hopper loading would allow you to continuously fire until the barrels melt, ammunition runs out, or the enemy breaks. The problem is just how much manpower it took to sustain any amount of cyclic firing at ~500-550 rounds per minute for the quad-40s. The autoloader removes the need for all that supporting manpower, but also removes the ability to sustain cyclic rate if the situation demands.
