[@AusFirewing]

Three details people might find interesting: Recoilless weapons have two main advantages over guided missiles. First, because they fire ballistic projectiles they are totally immune to all soft-kill protection systems. A bullet cannot be jammed, spoofed, or otherwise seduced. Second, because there is no rocket in the projectile, recoilless guns tend to generate a lot less smoke and noise, so it can be more difficult to actually find the shooter and retaliate. Thirdly, the reason why recoilless weapons can't be fired indoors isn't just that propellant gases come out the back, but that it also creates a concussive wave that can bounce off walls and other solid objects. If contained inside a room, these reflecting waves can overlap and turn anything inside the room into jelly.

[@therealspeedwagon1451]

One major disadvantage they’d have though is that they’re mainly high explosive or shaped charge and HEAT. That would mean that the best counter to recoilless weapons would be some ERA. Unless someone decides to invent tandem charge recoilless rounds, but since recoilless rifles are hardly ever used in a world full of guided missiles, that is a bit of a moot point.

[@AusFirewing]

That's true, though there's nothing technically stopping you from making a kinetic recoilless round. The problem is making one go fast enough while also making the launch tube light enough to be carried around. It's the same reason why tank guns have never gone above 120mm or so in calibre. Sure, 130 or 140mm sounds good on paper, but the size and weight of the gun breech needed for such a round is usually too impractical for an MBT. You might be able to make a recoilless sabot cartridge work, though They've done it for .50 cal...

[@許進曾]

@@therealspeedwagon1451you can just volley fire that with multiple recoiless rifle. Much harder to do with missile since it cost more both for the launcher and ammunition. Also recoiless rifle has the benefit of not needing to sit there and guide the missile so chances of retaliating fire is much smaller.(before third generation fire and forget anti tank missile like the javelin exist). This is also part of the reason for the argument of tanks, consider it can deliver long range, accurate, and immediate fire against targets(yes you can runaway against missile when at long range, not so against a cannon round flying towards a target at Mach five.)

The SPG-9 and M40 (and their various copies) are extremely popular to this day, seeing service not only with militant groups but also major armies. They're a great way to add huge firepower to a small vehicle very cheaply, and their light weight allows for them to be carried by only a few soldiers for easy battlefield infantry support.

There are countries that can afford to equip their frontline troops with expensive but much more effective weaponry, and then there is everyone else.

Fields of fire and different ranges between different kinds of AT weapons were intended to supplement each other.

Would u ever do a video about the differences between Mortars, Howitzers and artillery ? like what classifies them as which ?

[@andrewlee8204]

Artillery is a blanket term for large caliber fire outside of visual range. Howitzers and mortars are both artillery pieces

[@miliket4tom]

Originally, idea of mortar came up when people were still doing fortress siege and realize instead of throwing explosive at the stone wall, it would be nice to be able to lob shells over it, so they need something that could fire at extreme high angle (45 degree and above) while the range is not a concern. They realize this can be achieve simply by making a shorter barrel howitzer and putting less gun powder in. And when they point it upward to shoot, they realize it looks a lot like... well, a 'mortar' (the tool you pound stuffs in it), and they named it after that to separate it from the long howitzers. With the advance of technology and warfare, people don't really need to lay siege too often anymore but realize it's still pretty neat to have a light arty unit that's highly maneuverable to cover the close combat range (in which normal howitzer would be inefficient, because it's too close), which the mortar fits perfectly. And you have the mortar today. So the idea behind mortar is a lighter, simpler cannon that only need to fire HE at short distances (compare to normal howitzer). Because of that, you don't need a lot of chamber pressure and that reflects in the design: most of them have shorter barrel, simpler breech and loading/firing mechanism, lighter chassis (because less recoil), easier/faster to deploy, need smaller crews to operate

[@herptek]

​@@miliket4tomBecause of the exlusively high angles of fire intended for (most) mortars it is relatively simple to have them mounted on a plate on the ground to absorb the recoil. The mechanism obviously doesn't need many moving parts or many heavy components other than the plate and the barrel, which is obviously advantageous even for footmobile use. I don't mean to nitpick but I would like to add that mortars are not technically cannon, which is yet another taxanomic category of artillery guns, separate from howitzers and mortars. Cannon are meant for low angles and usually have high muzzle velocities.

7:22 This is a common misconception, this modified vespa did exist, and they were quite successfully used during the french colonial wars, but they weren't meant to fire while mounted, it was simply a mean to carry the gun, which was then used on the ground using a lightweight folding tripod stored in the vespa. The reason for it being recoilless is to accommodate the rather low weight capacity of the vespa, even despite the souped up engine of the military models.

Zeppelins (dirigibles) and even blimps are an interesting case. The British initially found them difficult to shoot down. Bullets would pass right through the bags of hydrogen gas. I think we all have a biased expectation from popping party balloons. (Were these rubber balloons as common 110 years ago? or were biases different?) Even party balloons do not have significant pressure in them, but enough to cause a pop or a rapid depressurization as they fly willy nilly. In dirigibles and even blimps the pressure difference with the surrounding air isn't very much, so unless the hole is very large the loss of gas is minimal and slow. It took incendiary bullets to shoot down German Zeppelins -- and even then it wasn't certain. An incendiary going off inside a bag of >90% hydrogen won't cause it to burn because that requires oxygen. So any burn has to happen where the bag meets the air.

I was commenting on a super slo-mo firing of a 76mm tank cannon and noticed the barrel moving rearward long before the projectile exited, which I, a high school graduate, theorized was the result of a 3in x 20+ foot column of air being pushed out of the barrel in the form of "ejecta" by the forthcoming projectile. i finally relented, he had a degree and I graduated with a D average.

@@peghead No, you're right. Here's what's happening. The professor is right when he says the recoil starts when the bullet is fired. What he doesn't say is that it's insignificant and barely noticeable at all. Okay, it might mess up a super long distance shot by raising the barrel a smidgeon, but not by much. The big recoil that we see is later and some of it is from the spent gas leaving the barrel and some of it is momentum stored in the mass of the gun. The bullet is tiny and goes at high speed. The gun is heavy and moves at slow speed. It takes time for it to react. I would say that you won that argument hands down. We won't beat up the professor because, technically, the recoil does start much earlier. The only problem with that answer is that it's insignificant at that time. Professors always miss the big picture. They focus on the little stuff and drive us nuts. It's what they do.

We used to have the 90mm recoiless rifles in the engineering units back in the eighties.

4:12 I find it hard to believe someone was arrested for design flaws

[@aleksandermate439]

Probably they had to blame someone for the money spent on a failure

[@Nacionarg]

Lol, for a gun design underperforming it does sound weird, but in a way design flaws can get you arrested in more serious cases and depending on each country's laws. In mine there's a legal figure called "mala praxis" ("bad practice" in Latin) by which a registered professional can be taken to trial if a blatant negligence was commited exercising the profession; I'm sure the same term is used in many other countries or at least the same concept has its own legal definition. Imagine Boeing chief engineers, the designers of the Italian bridge that collapsed, Fukujima plant builders failing to make the plant resist a tsunami, etc. They all will be or have been taken to trial due to design flaws. But again these were extreme and fatal design flaws, not a mere "we thought it would be better" like the example in this video.

[@ZS-rw4qq]

Sounds to me like one of those USSR myths State Department wants you to believe

[@kindlingking]

That is correct. In reality the guy worked for almost a decade on his cannon, siphoned a ton of government funding thanks to Tukhachevsky taking interest in his project and covering up for him, forced others to develop an entirely new plane for him and in the end achieved nothing, beside destroying many prototypes (his cannon tore the plane apart after just couple of shots) and giving pilots testing them serious concussions. And if you're interested, no, DRC didn't find it's footing in ground and sea forces either due to numerous flaws and steep competition (he also had no one to cover him here and handwave poor test results with "he'll fix it later"). He probably just would've got a jail time (again) if he hadn't been caught up in the Communist Party's internal struggles.

[@dimasdaffa5510]

The question is. Are the bazooka also consider recoiless rifle since it also has the gas exhaust?

[@pancytryna9378]

Yes

[@brucermarino]

I think not since the combustion happens on the projectile it is considered a rocket. The tube of the bazooka is for guidance of the round and projectile of the firer. A recoilless device contains and directs the propulsive charge. Thanks!

[@MrAracag]

I'm still wondering why there hasn't been any movement on the gyrojet guns. And possibly tank guns with the same tech?

[@pancytryna9378]

Expensive and useless?

YES! Wish u make video about the assault rifles such as the evolution of the M16s?

[@je6874]

Were they used against tanks?

[@dustybrand]

My next door neighbor growing up was retired Army. Some time in the late 50s he was in college and his brother was in the back of a jeep on a training exercise and was decapitated by a recoilless rifle.

[@honorguardsfencingclub7322]

The video is wrong regarding zeppelins - being filled with flammable hydrogen gas, many were downed in flames by machine gun fire.

[@Sophocles13]

I wonder if you took a page from the Davis gun idea and applied it to modern recoilless rifles though... what if you added a quantity of dense powder, like lead powder? It would be expelled out the back with the regular backblast of the recoilless rifle, but if, for instance, you expelled half the mass of tbe projectile in lead powder, you would half the propellant that would normally need to be expelled backwards. This would allow more energy to push the projectile and limit the backblast, making it easier to fire in confined spaces etc, and since it's powdered, you wouldn't really have to worry about injuring anyone anymore than the backblast already would have... *Edit* of course, after 10:00 he explains a system that utilizes just what I was imagining... oh well, at least it confirms that it was a valid idea

There is a town in india called Pattonnagar (city of pattons) it has a graveyard of pakistani patton tanks taken out by recoil-less guns mounted on jeeps.

[@edwardloomis887]

The U.S. Berlin Brigade during the Cold War was one of the last to retain 90mm recoilless rifles in the 1980s. Urban environments are less suited to wire-guided missiles due to minimum distances to get the missile tracker back on the target and things wires can get hung up on. Recoilless rifles were great as shoot-and-scoot weapons, but the backblast meant it most likely could not be fired from inside a building.

[@kolinmartz]

Technically the AT4 also partially solved the back blast issue by packing the back end with salt.
