History of the Krummlauf Device: Hitler's Folly (One of Many)

All the best firearms history channels streaming to all major devices:
weaponsandwar.tv
Today we are taking a look at the backstory of the famously recognizable Krummlauf device, the curved barrel attachment for the StG-44. It is really a perfect example of how German late-war desperation weapons took shape. It went from an idea nobody actually wanted to an impossible development program in the chaos of the German defeat.
You can see my previous video on an example of the Krummlauf (from 2014) here:

Coincidently I just watched a episode Of Mythbusters about this. They used a simple .22 rifle for the test. Surprisingly, it actually worked quite well. Not with a device that clamps on the muzzle, but with a bend barrel that is curved as smoothly as possible. They tried it all the way to 180° (which is admittedly not very useful, unless you want to commit suicide) and it still only lost about 10% of the muzzle velocity of a straight barreled gun. However, they only shot a few rounds each, so it didn't say anything about durability. But it worked.

[@MisterApol]

I thought they tried it with a 6.5mm Carcano too, but I may be misremembering the episode.

[@mariut00]

yeah! people think that magically bending a barrel will make it blow or plug, but its pretty much dependent on the smoothness of the curve and caliber used

[@oskarskalski2982]

Demolition Ranch also has episode with bent barrels and it worked fine with 180 and 5.56, rifle shot it's optics:D.

[@tomjagiello5119]

The issue is not that it didn't work at all, but that it didn't work well enough. What's the point of "curving" a bullet, if you can't hit things? Besides the idea for infantry is silly as the scenarios where this would really work are very limited and also come with limitations like the height of average dug outs affecting how much your head sticks out for example. You'd probably be better off with a rifle on a stick from WW1.

[@Gameprojordan]

Demolition ranch did a crazy video where he set up a bunch of pipes and shot a gun through the tip, and the bullet traveled down the entirety of the pipe contraption (tons of bends and such) and launched out the end

It's interesting that they kept trying to do the curved barrel instead of what the "CornerShot" ended up doing with decoupling the shooty parts from the holdy parts. Like, some sort of "pistol on a stick" with a remote trigger.

Here's the thing with the CornerShot though - why don't we just use a helmet mounted HUD with a camera on a pistol, you just stick the pistol around the corner? Surely I would hope that "hand exposure" wouldn't be the excuse lol. And, oh look, you end up carrying perfectly normal guns in that case instead of these big, cumbersome contraptions.

[@Matthew-bc9mr]

Reminds me of the flatline barrel I had on my old tippmann 98 paintball gun. Curved up about 20-30* then flattened out for the last 6" or so to induce backspin on the balls. Had to aim low at short range inside of about 10yds. But then they stabilized and gave me an extra 50yds of range over any other paintball gun so I could easily snipe people while they were trying to lob rounds in a huge arch trying to reach me. But their balls would fall short or the occasional ones that made it would bounce off me harmlessly while I could shoot flat and mark them up. Later tippmann came out with the apex barrel that I had on my A5. It was more standard looking straight barrel with what looked like a fat can on the end for the last 6". It had a slider on it for an adjustable hop-up. And could be rotated in 90* intervals. So with it spun upwards to 12o'clock and the hop-up slider maxed out, it operated just like the flatline, but you could back the slider off to eliminate the hop-up effect for closer range so you didn't have to aim low like with the flatline. And the really cool part was you could twist it to either side like 9o'clock or 3o'clock and max out the hop-up and it would put a side spin on the balls so they would go out about 50ft or so and then start curving off to the side to basically shoot around walls. Or flipped down to 6o'clock to drop balls down over the top of cover. It was a very slick setup and worked as well as advertised. Nobody was safe at that point. The tricks you can do when using spherical projectiles..

After seeing Mike's video, I'm suprised the Germans tested this thing for groups at 50 meters, he couldn't even get anything reliable at roughly half that (25-30 yards). Equally interesting is how high the Germans had to aim over the target, where in Mike's (very limited) testing it tended to shoot high instead. It's another great example of how you can track Hitler's (and his staff's) ever declining mental capacity throughout the war just by looking at the more insane "Wunderwaffen" ideas being put into production.

Germans and Brits had some of the more outrageous ones.

[@Grubnar]

And sometimes those crazy ideas worked! The bomb that skips across water (and over the torpedo nets), or a bomb that buries itself into the ground and destroys the foundation of a bridge rather than trying to hit the bridge itself. Or a bomb that can pierce through multiple layers of concrete. My favorite is "The Funnies!"

When the US Army Ordnance Museum was still in Aberdeen, they had several examples of the Krummlauf device.

[@undeadfrak]

The idea that comes to my mind is what if the Tank version of this idea was experimented with instead? What if the special tank turret idea was played with more? The tank version, with all of its fixed sights and more durable construction, could have been something used by infantry only in specially built bunkers (not something they would have to carry around, but something that engineers could build for them to man). Like, if on the beaches of Normandy these things were mounted on bunkers to allow troops to fire into places that the machine guns could not without exposing the soldiers. That's the only way I can imagine this idea working at all. Like a lot of "Wonder Weapons" I'm curious what it could have been if it was given more time, effort, and reasonable expectations, but, of course, anyone with the available time, effort, and reasonable expectations wouldn't have tried developing these "Wonder Weapons". Like, what if instead of this just being something that attaches to an existing gun, the gun and cartridge were built around this idea? With a smaller bullet moving slower the damage to the curved barrel would be much lower. If you were going that far, though, could you instead just have an entire pistol/SMG with a short barrel at the top of a periscope? For the Tank version something small could be enough to deal with infantry too close for the mounted machine gun to hit, especially since this device doesn't need to be effective past 200m. For this infantry the same idea I had before applies. Something like this could be mounted on a bunker to fill the gaps that the machine guns can't hit without exposing the soldier. I mean, what is a bunker if not just an immobile tank made of concrete? Again, anyone with the actual ability to develop something like this would probably just develop something else instead. It's just fun to speculate about.

[@nematic529]

WWII Geman Hetzer TD already had external machineguns that could be fired inside the vehicle with periscopes and handlebars. Few tanks had those systems (and nowadays a lot have thanks to advancement of cameras and motors). I doubt curving the barrel is the solution.

[@mahbriggs]

Several decades ago I read an article in a magazine about these weapons. At the time, it was thought they were for shooting around corners of buildings. The battles of Stalingrad were mentioned! Inyeresting that they were for trench or foxholes! In WW1, various nations had a variety of mounts, and periscopes fitted to conventional rifles to allow them to fire over the top of the trench with out exposing the shooter, including a folding rifle stock for the 1903 Springfield. Apparently the latter was never fielded. There is an interresting article in the American Rifleman posted on line on April 5, 2018, "Sniping from below: Periscope Rifles in WW1" by Tom Laemlein

[@jeromethiel4323]

Much more effective is what the US (and others, probably) tried to develop with things like the "land warrior" concept. Where you mount a camera to the rifle, and the sight is mounted in the helmet. Can't shoot around corners, but you can hold the rifle around the corner and shoot that way, so kinda the same thing? I do see this as inevitable tech, it's just not quite there yet. Of course, semi-autonomous drones are probably where we are headed. Send the drones in, then pick one and assign a soldier to remote operate it. Your trained soldier isn't exposed to danger, and the drone can do the boring part (getting into position) at least mostly on it's own. Imagine a drone that can fly into a contested area, land, and set up surveillance. It detects possible targets, a soldier gets assigned to the drone, assesses the situation, and can fire whatever ordinance the drone is carrying if it is deemed worth while.

[@davidnicholas7516]

Hitler throughout his reign had lots of crazy ideas, especially involving weird or incredibly large technological developments, often made with little or no reference to reality. There were actually enormous battleships on the drawing board (the H44 was so big it wouldn't have fit through the Kiel Canal), ridiculously large tanks (good luck getting them across a river, given that no bridge was rated for something weighing 100 tons), tanks armed with rocket propelled mortars as a main armament (the vehicle could only carry 12 or so rounds, and had to withdraw from combat for each reloading because it was a muzzle-loaded gun with an actual crane to assist the crew in loading), rocket planes (propelled by liquid rocket fuel, which tended to melt the metal bottle it was contained in, and then melt the pilot for good measure), multi-engine bombers that could supposedly fly to New York City with a bomb load and then safely return, and so forth. The Krummlauf was somewhat crazy, but given it actually sort of worked, he had crazier ideas.

They have one of these in the Kentucky Military History museum in Frankfort, which is where I saw it for the first time back in 1960. Colonel George Chinn, author of “The Machine Gun” was their curator and in charge of their collection for many years. You should come here and visit them.

I had read of those in Phillip Sharpe’s The Rifle in America, published shortly post WWII. Sharpe was entertaining, but not a very careful researcher. He was attached to US Army ordnance late in the war, and described the Krummlauf as having vicious side recoil.

There was an experimental Sten Mk.V to shoot around corners. Instead of bending the Sten's barrel, they fitted a pivoting stock and front grip. Aiming was done through a prism attached the rear sight.

Came straight here from GTs' video! Fascinating weapon attachment.

My respect for Ian went up another few notches with his excited support and shout-out to Garand Thumb! Great example for other YT producers!!

WHAT A GREAT DAY TO BE SUBSCRIBED TO BOTH CHANNELS

[@pittuk6500]

How is this possible you and Garand release a video about the same subject at the same time

[@lieutenantcoloneltanyavond8273]

There are this things on the internet people use to communicate with each other. You can write what you want to say, press "enter" and the message gets sent to the recipient. Some even support voice communication. With this miracle of science people can talk with each other to, for example, synchronize video release! It's amazing!

The helmet version would be probably mounted to the recesses of the helmet, which was initially designed for visors.

[@TheWalterKurtz]

You can tell that Ian, as an engineer, is chomping at the bitt to develop this idea.

[@77gravity]

Mythbusters did this, started with small bends, made them bigger, they ended up (if I remember correctly) with a 180deg bend, and it still spat out a bullet at deadly speed.

[@magoshighlands4074]

When it comes to the British experiments, it's possible we considered the idea at the start of the war when we were still worried about invasion, knowing us some engineer in a shed bolted one together and found out it was crap

[@bikkiikun]

FYI, That "J" is actually an "I", in the older scripts. On the 'I' that hook sits on the standard base line/level as most other letters. The hook on a 'J' goes below the base line, like lower case 'g', 'p', 'q', etc..

[@ftn5546]

I figured this was coming after Mike dropped the firing video of this.

[@BronZeage]

Not the first time a smart ass joke suggestion(Sure, why don't we bend the barrel down to shoot at the ground) gets taken seriously because the situation is just that out of control.

[@noobepro_7146]

At the same time garand thumb making video about this topic too

[@berrie-nice-to-meet-you]

Meanwhile Demolition Ranch was able to Looney Toons this concept into working

[@oddspaghetti4287]

I wonder why they didn't just develop it for the MP 40 to start with? It will be a short range device anyhow and the 9mm bullet is going pretty slow and likely wont cause much damage on the curved barrel. I think the program would work out pretty easy in 9mm.

[@bristleback3614]

Crazy. In any shooting game, tank main job is to protect the foot soldier while advancing but in real life the foot soldier actually is the one that actually protecting the tank

One of the old C.B. Colby weapons books has a picture of a US soldier posed with an M3a1 with a curved barrel being used to shoot around a corner.

[@keaixiaomeinv]

Garand Thumb's videos are fantastic if you want to see cool guns go pew pew in slow motion. Ian's videos are great if you want to learn something.

[@Nikolai1939]

I imagine the helmet mounted sight would look like the german snipers in Wolfenstein the old blood, with that gigantic lens sticking out

[@geodkyt]

Honestly, the P-version would have probably been at least as effective, cheaper, and easier to handle inside the vehicle, if they had focussed development on 9x19mm SMG as the host gun. Lower pressure, lower velocity, rounder bullets, and do youbreally care if an FMJ pistol bullet is tumbling when it hits meat at close range? Honestly, you aren't going to be making hits in combat at the outer reaches of the nominal dead zone (say, 50-150 meters) *anyway* . Even a tumbling pistol bullet going subsonic slapoing into an enemy soldier sideways at 50m is still a harder hit than a fragment from a hand grenade at 5 to 10 meters. More than adequate to disrupt a grunt trying to close close enough to theaten a tank with antitank grenades. The idea still generally sucks, and the stuff the Rhodesians tried to protect farm truck convoys (like a daisy wheel of shotgun barrels with a crank handle to fire them in succession) would work better. And before anyone asks, "But what about nearby friendly infantry? Won't you risk hitting them?" Look, if youve got friendly infantry around your tanks as you enter an area where enemy infantry might be, it's those infantrymen who are supposed to keep the enemy tank killer teams off you. That's literally why you *have* an infantry screen. 😅
