Armstrong 7-inch Rifled Breech Loading Gun (1861 - 1902)

- The Armstrong 7 inch (110 pounder) rifled breech loaded gun was constructed using Armstrong’s method of shrinking concentric wrought iron hoops over a toughened and rifled A tube.
The rifling consisted of 76 grooves, and the shell was coated with a thin sleeve of lead that gripped the rifling.
The 7 inch gun was ordered by the British Government, despite Armstrong’s view that the mechanism was unsuited to heavy guns. The first guns entered service in 1861, but it became clear in naval use that the shells did not have the velocity to penetrate the armour of warships of that era. While the Royal Navy then reverted to muzzle loaded guns, albeit rifled rather than smoothbore in 1864, the 7 inch rifled breech-loaded Armstrong guns were supplied to the coastal defence forts (Palmerston Forts) built during 1860 -1870s. Some of the 7 inch guns remained in service until 1902.
Many of these Palmerston’s Forts were designed to protect major ports from an invading force that landed nearby and attacked from the landward side. These forts became known as ‘Palmerston’s Follies’ as the guns faced inland.
The 7 inch Armstrong guns were well suited to defending against an invading army, firing explosive shells against siege works, segmented shell agains large bodies of men or equipment and canister shot at short ranges. The guns and their crews had to be protected. This was either by mounting the guns in casemates or the novel disappearing gun mounting invented by Sir Alexander Moncrieff (1829 - 1906) in 1858. The Moncrieff mounting allowed the gun to be reloaded while protected by a thick parapet, then raised to fire, only exposing the gun briefly. The Moncrieff system also allowed the gun to be trained over a wide arc, unlike the casemate guns which were limited by the gun port.
This animation was created using Cinema 4D, Quicktime and iMovie.

Wonderful Rob! Love the gun system videos! So much work and it shows.
I really enjoyed the demonstration of the disappearing gun mechanism.

I found the fuze system very interesting.
Excellent model work, as always. These are not only very entertaining, but they really let you wrap your head around how these things work. Something that can often be very hard to do with just words or a simple illustration.

@@vbbsmyt Hello, could you please send me a 3D drawing of the Moncrieff RBL 7-inch gun? I want to make it into a model. Thank you very much.
You sir are an artist. This level of skill is incredible.
Thank you, Mr. Brassington. I'm reading David Weber's Safehold scifi book series right now, and they talk about building guns just like this, jumping from effectively 16th-century tech to late 19th-century in a matter of years. It's very helpful to see what this intermediate gun technology actually looked like/operated.
(I had no idea there was a vent block like that in Armstrong guns, for example.)
Thats series is a great read
@@battleoid2411 You saw Weber got pretty tired of writing it (or maybe was forced to to tie it off) towards the last book. The man writes too much!😂
@@MM22966 yeah, he goes all out on his books, its what I love about them but yeah it takes a lot of effort for him to write them
The best channel going explaining how these old weapons were designed and worked.....simple, clear and concise and not cluttered by a bunch of needless verbiage. Please keep up the excellent and interesting work.....ps. music choice is great as well.
Absolutely excellent work! The RBL Armstrong was always a bit curious to me. I never knew about the tin gas seal which makes a lot more sense in hindsight than a straight conical fit between the breech-piece and breech face, but I still have to wonder why he went with a plug-secured block to close the breech, since it kind of seems you get the disadvantages of both sliding-block and screw-plug breeches. I will say, the combination of the gas seal, booster charge, loading tray breech insert, and uninterrupted screw explain why the RN felt the guns were excessively labor-intensive. Though, next to the RML 12.5-inch this seems positively convenient.

Wow. That fuse timer mechanism is sweet. Love the video!
Amazing work as always detailing how these amazing Victorian era marvels work. Thank you so much for everything you do and as usual I look forward to your next video with great anticipation. If possible do you think you could do a history of shell development in one of your future videos? I would really be interested in seeing how they evolved over time all in one video. But no matter what you do I know I will love it!

The shell simulation is very interesting! You should try making a video on the Type 3 "San Shiki" AA rounds that Japan used in WW2.
Or if you want to try something rarer, the "Brandshrapnell" incendiary AA rounds Germany made in WW2.
This is outstanding. Thank you for the time and effort in sharing. We really appreciate it. This is amazing knowledge
These never cease to amaze me.
back when we needed him most
Emplaced in HMS warrior I believe.
This was the gun used on HMS Warrior. It also helped convince the RN to stick with muzzle loads for a lot longer. Thanks for the work though!
Great show!
Happy new year!
Many successful presentations. I didn't realize shooting this gun was so complicated.
Wonderful visualization....these looked pretty accurate for their day too....thanks for posting.

Late Christmas Gift. Thanks
Yet again you have excelled yourself with another high quality presentation .Well Done .🥇
That's one big gun
Thanks for this wonderful video. Yesterday I actually posted a Short on a 7” Armstrong that’s on the HMS Warrior in Portsmouth UK. It was great seeing the workings, I never knew about the tin gas seal.

"Wanna see a magic trick?"
BOOOM!!!
"-and it's gone!"
An excellent display of a 110 lb armstrong gun! When I was with the Palmerston Artillery volunteers we went to Crownhill fort for a weeken special. Sadly at the time their Moncrieff gun was in poor condition and we couldn't elevate it. But they have fixed it now and it's impressing to see. The one we had at Fort Nelson was always good for display and I still have "fond" memories of how heavy the breach block was and keeping your footing with hobnail boots.
If I may, I'd suggest the 32lp SBBL gun next . This was a 32 pounder with the rear cut away and replaced with a sliding breech. They were mainly used in caponiers to act as anti infantry guns. Firing Case shot and Grape shot down the ditch and clearing away enemy forces trying to scale the walls.
vectorbrony. Thanks for your comment. As a PAV team member you will, perhaps, have noted that at Fort Nelson, the gunner on the left fires the gun, while in the video, he is on the right. I am informed that the PAV team are working from the 1885 drill book, while the video drill is from the 1992 manual. So both are correct.
I will see if I can find drawings (essential) and a manual for the 32 pounder SBBL gun, but no promises. R

My idea is to cooperate with the local cultural relics bureau to sell these models, or to keep them in private collections.
Amazing animations, as always, right on the point. Great detail too, keep up the good work.
Have you considered making an animation of the type 93 japanese torpedo? It's quite the machine.
As always, I would need good drawings. Where can I get these from?
Fascinating! Did this model have the flash problem around the breech that the naval versions did? Did that problem result in their being removed from ships?

Any intention to do v1? it is very simple, and no electronics :-)
I'm surprised that it took until 1897 for hydraulic recoil mechanism to be added to artillery.
Fascinating, thank you.

so nice to see a new video from you..
Great video! Would you consider doing a video on the PaK 36 gun?
Great start to the year, thank you. The tin cup used to obturate is something I wasn't aware of, was it hooked out and re used or a new one every time?
The tin cup was the hardest item to research. I have not found an existing example or drawing (so far). It should have been removed from the vent piece after each shot using a special tool, but again I haven’t got the drawing. The tin cup, however, was essential. If, in the heat of battle, the old one was not removed, or a new one fitted in place correctly, there was a great risk of the blast expelling the vent piece explosively, to the detriment of the crew and surroundings.

As always, it's great. I was already getting worried.

супер, оч интересно )) спасибо
Excelente apresentação. Percebemos como era complicado usar canhões como esse. Em que lugares eles foram utilizados?
bravo sir!
The explosions caused by the breeches of these guns failing set back the RN’s adoption of breechloading guns for about a decade.
I just discovered this channel yesterday, and I've already watched almost every video. Wonderful rendering and animation! I really get a truly inside look at how these weapons work. Your channel deserves 100 times the subscribers!

shell fuse's ignition was triggered by inertia?
Yes. In the smooth bore shell guns, this Boxer (Colonel Edward Mounier Boxer, RA) type time fuze was initiated simply by the blow-by of gunpowder combustion gases. This was obviously not feasible or reliable in a rifled gun with gas seals, so inertia initiation was used.
Bravo! Im very glad I was not an artillery man of that era.
The title is not good it should state that it is a DISAPPEARING gun as otherwise it is a gun like others of that era!!! Otherwise its a very good video👍👍👍
Amazing renderings. The descending carriage gun was made obsolete when battleships gained very thick side armor. Then a gun needed to drop a shell onto the deck from a high angle to be successful. Like happened with the HMS Hood.
@ZaHandle My understanding is that she got hit behind her funnel from behind as she turned in an area they had planned to upgrade the armor to but spent time showing the flag around the world instead>
More likely the descending carriage guns could not be scaled up to WW 1 level battleship gun size effectively and rate of fire for WW 1 5-8" guns was was much faster, you also lacked overhead protection who was bad as air-burst became more accurate.

Very nice video and explanation of the mechanism 👍😀
I was wondering how the recoil forces are dampened in this construction….
The recoil is huge and on other guns there are hydraulic dampers to absorb the recoil.
But how does it work on this mechanism and they prevent the gun from banging back down.
Is there a mechanical brake on the ratchet mechanism ?…. That acts like a brake and this friction dissipates the recoil energy ?…
At the base of the carriage is a heavy weight, When the gun fires, the carriage rotates, lifting the heavy weight up, like a pendulum. There are 2 sets of ratchets, one on the top of the yellow arm, which stops the carriage from falling back, and the second set within the brake drum. The clever design means that the recoil force is entirely absorbed by lifting the weight while rotating the carriage to its loading position.

Are you going to do on for the hydro-pneumatic carriage as used in most of the colonies.
Ayo dats really cool rob
another outstandingly made video. complex breech lock mechanism and shells. Ahead of its time. thank you

Firing and reloading this early breech loading gun takes forever! Not sure if it was significantly faster than muzzle loading guns?
i don't think that safety cap would do anything if the shell was fired
Excellent video!
Greetings from the Netherlands 🇳🇱.
Would the 12 and 20 pounder Rifled Armstrong guns be loaded in the exact same way, or was there some minor variation?
Minus the popup, isv this the same as the 110lb Armstrong's on Warrior?
I can certainly understand (if not agree) with why the Victorian establishment discontinued Armstrongs and went back to muzzleloaders for a while. This is fiendishly complex and the tech just probably wasn't quite mature enough yet when these were first introduced. It took until Krupp to perfect the breechloading cannon.
Surprise! It’s me the Armstrong 7-Inch breach loading gun, don’t ask me why I just popped up from nowhere, time to DIE!
On a more serious note how expensive was it per shot, and how fast could the cannon be reloaded?
😎
Wonderful, so much effort taken to make it easily understandable for newcomers like me. Thank you for the video.
Complimenti! Non ci avrei mai creduto se non lo avessi visto.
Pensavo che nel 1860 fosse tutto più rudimentale. Ottima creazione 3D. GRAZIE!
We have one (or 2 actually I think) of those cannons at my job. Beautiful pieces of engineering
cool
This deaign was a lot more clever than history books indicated, But the interrupted thread would have helped a lot
I think they had one of these in the fort that is now part of the Wellington Botanic Gardens. Now part of an area with a weather station, a Cub Scout hall and several observatories.
Can you make a video about the bergmann bayard 1894 pistol or the lemat revolver

Interesting breech loading system.
I wonder if people rode the gun up to its elevated position
Как же резко артиллерия усложнилась с началом Научной Революции после Наполеоновских войн. При Наполеоне те же арт системы по сути что и за пару веков до этого. А тут вдруг взлет ракеты натурально и резкое усложнение. Даже по количеству операций, требуемых для производства выстрела, видно как все усложнилось. Смотреть конечно, залипательно)
Great stuff

I have a question for historians who may be familiar with this cannon. How long would the average gun take to be set up like this and fired?
Doesn't look very accurate.
