A batch of upgraded MLRS "Grad" entered the troops

The Ministry of Defense received a batch of upgraded Grad multiple launch rocket systems. According to the press service of Rostec, the equipment was delivered as part of the state defense order.

The military division of "Motovilikhinskiye Zavody" handed over to the military a batch of MLRS "Grad" in a modern modification ("Tornado-G"). The equipment has already been shipped and went to the places of service. How many installations were included in the batch is not reported.

MLRS "Grad" (9K51) - multiple launch rocket system of 122 mm caliber, adopted by the army in 1963. In 2014, the Tornado-G MLRS, a modernized version of the Grad, was put into service. Currently, all Grad MLRS are being upgraded to the Tornado-G level.

The upgraded MLRS "Grad" is designed to destroy enemy personnel and armored vehicles in places of concentration, on the march and in combat formations. The combat vehicle is equipped with an automated guidance and fire control system. The maximum firing range is 40 km, and the time for a full salvo of 40 guides is 20 seconds.

The modernized "Grad", which changed its name to "Tornado-G", also received new ammunition, completely updating its arsenal. In 2018, Tekhmash presented three new 122 mm projectiles for MLRS: an unguided projectile with a detachable high-explosive fragmentation warhead of increased efficiency, an unguided rocket projectile with a cluster warhead with cumulative fragmentation warheads, and an unguided rocket projectile with a high-explosive fragmentation warhead part of increased power, as well as a guided projectile with increased range and accuracy.

The design of the modernized vehicle itself remained unchanged, the main update affected the fire control system. New modern electronic equipment has been installed on the machine, which makes it possible to independently carry out all the calculations related to the launch, which was previously done by the crew commander. In addition, the updated Gradas are integrated into modern automated control systems, which makes it possible to control the installation remotely in real time.

I don’t understand one thing, why they don’t put outriggers on Grads? Indeed, during operation, the installation sways on the springs and the accuracy drops, because the missiles there do not seem to be homing.

[Vladimir 290]

Everything is there, be sure to hang it on jacks before shooting (the back of the installation is just not visible in the photo)

[Proton]

I don’t remember that Grads had outriggers.
But there is a swing blocking system.
And outriggers are not needed for a simple reason - the recoil is not as strong as that of the barrels.

[75 Sergey]

even if there are blockages, then it sways on the tires hoo, the blocking of the springs will not solve anything, and even if it gets into resonance during intense fire ...

[Proton]

I repeat once again - there are blockages from swinging.
From the Grad system (based on 375 Urals) repeatedly fired, there is no "hoo" rocking.
Targets are hit according to calculations. Unlike Tornadoes, the calculations are simpler.
I have no idea what "intense" fire is, I don't remember the term "getting into resonance" either. There is shooting, shooting in one gulp.
And in order to understand how the designers got around the strong rocking during a salvo, you need to know the order of leaving the rails.
I hope you remember how informally the "joystick" for the electric control of the guide package is called?

[Proton]

That's right - in the photo, the front props are just for the exhibition.
When designing the Grad, the order of the projectiles leaving the guides was specially developed in order to compensate for the swing as much as possible.
From the contact covers of the shells, chic ashtrays are obtained. During a salvo, they scatter for many meters around the BM. A "joystick" is called a cheburashka. The main thing is not to turn on the cheburashka at the same time horizontal and vertical aiming - the fuses can blow out. You have to oil manually.
Just don't tell anyone else.

[NKT]

They used to be, both in front and behind, now - I don’t know ...

[VicktorVR]

I'll reveal a terrible secret :)
Recoil like art. The launcher has no guns at all, moreover, the RS, when launched, pulls the launcher forward behind it.
Plus, the changing weight of the launcher when the RS leaves the guide.

[neurostimulator]

Because the distribution of the probability of hits during shooting is uniform (this is not an adjective, this is the name of the distribution law of a random variable).
Unguided projectiles cover the area, not the target. For such shooting, the buildup of the machine is not so important.
Shooting with guided projectiles is also not strongly tied to the stabilization of the chassis on the supporting surface - the accuracy of their hit is ensured by self-correction of the trajectory already in flight.
High-speed anti-aircraft artillery (more than 500 rounds per minute) also does not hit one point, otherwise the probability of being hit is reduced.

[Crimean partisan 1974]

Rapid-fire anti-aircraft artillery (more than 500 rounds per minute)

... everything is pralno .... from the Soviet gatling AK-630 there is also no "squirrel in the eye" I no longer remind you of "Daggers" "Broadswords" and even in Shells ......

[neurostimulator]

The squirrel jumps fast, its eye is better considered as a general population (we are not talking about generals and their .. hobbies). A hit is like a mathematical expectation. That's when it will be "a squirrel in the eye", no matter how much you jump.
Shooting with such accuracy at squirrels in automatic mode was learned only in the USSR.
Evidence from behind the hillock that if "Shilka" took aim, then "without gifts" they will no longer let go - a lot, for different times.

[Crimean partisan 1974]

The squirrel jumps fast

.... sometimes it stops and then oops ... a Siberian with small things ..... well, if the topic ... then the MLRS is the MLRS .... although it would be nice to install an intelligent inertial system in the RSs .... Basically it's not hard...

[neurostimulator]

This is not required, there are high-precision shots even for the BM-21.
But for a caliber of 220 mm or more, it is already required and it is there - the range is greater, and the accuracy is needed higher than that of the BM-xx series. Even unguided rockets in this case have gyroscopic stabilization.
Of course, a gyroscope, in the full sense of the word, is not installed there, but if you dig around on the Internet, you can find the fundamental structure of such ammunition, if you are interested.

[Crimean partisan 1974]

Of course, a gyroscope in the full sense of the word is not installed there

..... but in vain ... for a long time there have been electronic gyroscopes the size of a matchbox ... so the designers could have pushed this topic, otherwise aerodynamic gyroscopy is already kind of wrong .... yes, it’s quite terrible ... but no ... 21st century all the same

[neurostimulator]

believe me, there’s nothing to it, the accuracy of the hit, and so, in short, is much higher (in unguided projectiles), the ammunition should be as cheap and easy to manufacture as possible. All three conditions, including accuracy, have already been achieved.

[Crimean partisan 1974]

All three conditions, including accuracy, have already been achieved.

.... well, well .. it’s already relieved in my soul ... I’ll go to the fridge and wave a hundred ...
nevertheless, an inertial system on the RS would not hurt ... it’s also not expensive, but the efficiency would really increase ..... the striped ones seemed to be tested on the MLRS, but I don’t know the results ... evil tongues say that everything seems to have gone well

[neurostimulator]

Successful, but expensive. As a result, they will lose everything ... because of their "achievements", including, and they can no longer be stopped, their main enemies are the stocks of their weapons already made and those that have already been approved in strategic planning ... and this cannot not to please, as I usually write in this case.

[Crimean partisan 1974]

and this cannot but rejoice,

... uh, for sure .... zumwalts. penguins ... combat lasers .. railguns ..... and the heavenly oops pushed the satellite out of geostationary orbit just now ... but how will this orbital utilizer push everything striped out of orbit. ..what will they do

[neurostimulator]

Joking, yes)) .. I am also an engineer, I also want to do better all the time, but ... the best is the enemy of the good.
And yet, if you know something very well, this does not mean that it is it that controls the whole world).

[Crimean partisan 1974]

Are you kidding, yes

... from the striped ones, yes .. and always .. there is something to joke about
I always want to do better, but ... the best is the enemy of the good.
.... and in what sciences do you excel .... if in thermodynamics, then I can provide a topic ... very funny ... caseless small arms ammunition ...

[neurostimulator]

Once, a very long time ago, everything seemed to be clear ... in thermodynamics))
Reset - exclusive material is always interesting, even if it is not very clear)).

[Crimean partisan 1974]

Reset - exclusive material is always interesting, even if it is not very clear)).

eh Fedot, .. well, an intriguer ... unfortunately, the quick calculations have been lost, because it was a long time ago and I have 3 prodigies who regularly cleaned up the hard drive with formatting, but I managed to pull out the jpg-drawings from an almost killed SD

[neurostimulator]

I will try to dig up something additionally, I do not promise a quick result. It is better to send a message off the topic of the article in personal correspondence, otherwise it is a violation of the rules of the forum, I already have 2 warnings in two days)).
I say - yet, but do not say goodbye.

[Crimean partisan 1974]

Off-topic post

.... yes, what’s off topic .. everything on the topic of the RS ... only the MLRS is large and without a small rifle case ...
well, and so "I'll try to dig up something additional" ... yes, in principle, there is no need for anything additional ... I am familiar from the articles with the German G11, the gunsmith Gerasimov, and most importantly with the activities of Shiryaev ... so what I provided nothing like ... and I believe that he has the right to life

[neurostimulator]

No, it seems that caseless cartridges are ammunition for compact weapons, and this topic is already familiar to me ... a little.

[Crimean partisan 1974]

ammunition for compact weapons,

.... that's it, .. the entire gross mass of the ammunition is used without leaving waste in the form of shells ... moreover, with cursory calculations, the provided ammunition, in any case, according to the laws of mechanics, will have a speed even at a distance of 1 km of about 1200 m per second well, it’s fluent, I won’t sit down for calculations again, I’ll give it to good caring hands .. moreover, it’s quite compact so that, in principle, it can be placed in handles like a pistol, which will reduce the dispersion of the center of mass when ammunition is consumed ... well, however, Shiryaev in practice tested an actively reactive bullet ... but recognized it as redundant .... such a story

[neurostimulator]

All in personal correspondence)).

[Crimean partisan 1974]

All in personal correspondence)).

yes, I don’t even know what it is ... sometimes they come in a personal. but these are friends ... but I don’t know how to do it myself

[neurostimulator]

Then I'll have to write a separate article for you)) In the meantime, that's it ... there will be material - I will find you

[Crimean partisan 1974]

i will find you

.... no question .. I will be happy to discuss ... just in case, I have a friend on this resource and part-time my friend Sergey Linik aka Bongo ... the author of wonderful articles about air defense and other radars of animals ... advanced on this resource ... through it if you can find me

[Vladimir 290]

I'm sorry, I really didn't see the jacks in the photo.

After all, during operation, the installation sways on the springs

=======
It does not sway: there are screw stops in the rear axle springs. Before firing, they fix the rear axle.

[lucul]

In addition, the updated Gradas are integrated into modern automated control systems, which makes it possible to control the installation remotely in real time.

The most tsimes)))

It's encouraging. The "old horse" does not spoil the furrow until now.

[yuriy55]

Here they are in all their glory:

Unguided projectiles cover the area, not the target.

But with only 40 shells of 122 mm, the area turns out to be quite large, but the density is quite low, if the jacks help to increase it, then this is probably useful

[neurostimulator]

They will cover them, tightly tightly, while they twirl the jacks. With jacks, you can only fight with the Papuans, who do not have MLRS.

Moreover, it seems that even the anti-shatter protection is not so good, it seems that the Polish lobster will have better

VicktorVR (Victor) wrote correctly. The MLRS has no recoil - the shells pull the BM forward, because. when fired, they must break the stopper by which they are held, and for this you need to gain a force of 360 kg. Supports are required to eliminate (reduce) the lateral swing of the BM - this is an addition to the special distribution of the firing order of the shells (it also affects the accuracy of fire). And there is another inexplicable fact - with an increase in the firing range of the MLRS, the accuracy of hits increases (the dispersion ellipse decreases).
