Work on the modernization of self-propelled guns 2S7M "Malka" completed

In Russia, work has completed on the modernization of the 2S7M Malka self-propelled gun. This 203 mm self-propelled gun is in service with the Russian Ground Forces. The first modification - 2C7 "Peony" - has been in operation since 1975, the upgraded version - 2C7M - since 1986.

According to the press service of Uraltransmash (part of UVZ), during the modernization of Malki, work was done to replace the gearbox, distribution mechanisms, and power supply units. Surveillance devices and guidance system, intercom equipment and radio station were replaced. Updated anti-nuclear defense complex. There was a possibility of aiming at the target with the help of UAVs.

The upgraded vehicle passed all the required tests, the first updated self-propelled gun was ready to be sent to the troops, the company announced its readiness for serial modernization of the existing fleet of self-propelled guns Malka.

Modernization improved driving performance, maneuverability and mobility, command controllability and all the main characteristics of the gun

- said in a statement.

It is worth noting that the 2S7M Malka, having a 2 mm gun caliber (44A203), is capable of firing various types of ammunition, including active-reactive and special ammunition with a nuclear warhead.

Large-caliber self-propelled guns at one time were developed as a means of possible tactical nuclear strike.

For reference: the 2S7M Malka combat mass in the previous layout was 46,5 tons, the crew was 6 people, the R-173 radio station was used, the transported ammunition was 8 rounds, and the self-propelled gun was put into combat position for 7 minutes.

[Zaurbek]

You can put a new barrel in a modern spirit ... and shoot 100-120 km with new shells.

[Teberii]

Then it’s easier to assemble a new car, and this is a tactical vehicle.

[Zaurbek]

On the tank, the barrel can be changed .... but not on the howitzer? Moreover, she does not have a tower.

[YOUR]

What is the point of replacing the barrel with a different caliber?

[Zaurbek]

Who wrote about another caliber? What is the difference between trunks on 152mm systems of the USSR and the Russian Federation? Or on 125mm tanks? Or NATO 155mm systems? Barrel length, Camora, barrel manufacturing, barrel materials .....

[venik]

======
Do not confuse the concept "trunk" And "gun"! Do not also compare smoothbore gun with threaded! And even more so, to compare 125 mm smoothbore tank guns and a rifled gun of extra-large power.
That substantially to increase the firing range, it is necessary to replace not only the barrel, but also the breech, knurling, lifting mechanisms, etc. etc. (in short - EVERYTHING!). Those. create fundamentally NEW gun! And this is difficult, costly and long ....
Here we are talking about modernization (during restoration), allowing you to slightly improve performance without huge costs!

[Lopatov]

Quote: venik

Do not confuse the concept of "barrel" and "gun"!

You did not understand.
Zaurbek proposes to install a new gun on the self-propelled guns.
As it was, for example, done with 2C1, by installing a 2A80 with a "body kit" getting the "Host" 2C34.

Moreover, the main characteristic of the new gun should be an increased firing range.

[novel66]

but not accuracy ??

[Lopatov]

Quote: novel xnumx

but not accuracy ??

On the contrary, accuracy will decrease.

[novel66]

But then what is the point?

[Lopatov]

Range.
There is a certain hobby. Quite incomprehensible in the presence of MLRS

[novel66]

and in the absence of adjustable ammunition

[venik]

Quote: Spade

You did not understand. Zaurbek proposes to install a new gun on the self-propelled guns.

=======
1. Did you understand what Zaurbek meant and that offers??
2. You seem to be an artilleryman? How much do you think the mass of a 203-mm long-range gun of this class will increase if the firing range is increased by 2, or even 2.5 times, as the respected Zaurbek suggests ??? Will the chassis pull this colossus? Or it will turn out like in that joke: "... And now we, together with all this bullshit try to take off ... "?

[novel66]

how to get? at such a range?

[Zaurbek]

How do you plan to get on 152-155mm systems at 50-70km?

[novel66]

there are adjustable shells, but for 203 I don’t know

[Bubuzon]

There is. Complex "Brave".

[Lopatov]

Quote: Bubuzon

Complex "Brave".

240-mm
Adjustable mine.

[Lopatov]

Quote: Zaurbek

How do you plan to get on 152-155mm systems at 50-70km?

Due to the number of shells. The more, the higher the probability of hitting the target.

[Zaurbek]

It’s already hard to hit 50km with ordinary shells .... and it makes no sense.

[novel66]

and this is not a step back

[mat-vey]

Quote: novel xnumx

and this is not a step back

This system was designed and created for the tasks of 50 years ago ... And with the development of their own and enemy's equipment of that level ...

[venik]

Quote: Zaurbek

The joke was once like this:
"1937. A new prisoner was brought into the cell. Inmates ask, they say - Who is that?
- Plumber!
- What article?
- Politically!
Everyone neighs: Well, where does the plumber have to do with politics? A man explains:
- They called me to the Regional Committee, change the tap (there they have a tap in the toilet leaking) .... Well, I looked, studied and said: "You can't get off by replacing one tap! THE WHOLE SYSTEM needs to be changed!"
So here: one barrel does not get off .....

[Zaurbek]

We need a projectile first .... an analogue of Excalibur ... massive and relatively inexpensive. And this is a problem not only of calibers from 100mm to 203mm, but also of MLRS systems and aviation ammunition and ammunition for UAVs. Therefore, it will be solved one way or another. If not, then another "Tsushima" or "Crimean War" awaits us

[Lopatov]

Quote: Zaurbek

First you need a shell .... analogue of Escalibur

It is much cheaper to create a guided missile for the Hurricane. And the rocket itself will be much more effective.

[Zaurbek]

Simplicity is the same ... you need a GOS ..... with the same principle of operation and price. And what is more expensive: a gun + shell or MLRS and Rocket should be considered an accountant. Here, logistics also plays a role and the fact that Malki is and will not do new ones ...

[Lopatov]

Quote: Zaurbek

Simplicity is the same

This is how the ARS "Petrel-2" looks like

The engine gobbled up almost a third of the weight of explosives
If you add a control system, it will be minus one third, no less.
And there will remain a 203-mm shell with the power of action at the target, like a 122-mm shell.

[Tektor]

There is a hope that our developers will be able to make a miracle, and they will be able to develop an adjustable active-reactive projectile with a direct-flow engine in a caliber of 203 mm, such as this (caliber 152 mm):

this one may even be hypersonic.

[Zaurbek]

Until some km, a projectile will be beneficial ... then a rocket. The knock-out shell is inexpensive. And the gun does another job.

[asv363]

Different overloads occur in the projectile and MLRS rocket at the time of the shot. The electronic "stuffing" of the projectile should be significantly more durable, and therefore more expensive.

[serezhasoldatow]

Khrushchev proclaimed such a thing in the 60s.

[Lopatov]

Quote: Zaurbek

This is not the main problem of this self-propelled gun.
Translation time and rate of fire. They make the self-propelled guns obsolete and not up to date.

[Zaurbek]

For such a range and accuracy, the rate of fire is enough for the eyes.

[Hermit21]

Fields in the 2000s offered for her shells with a range of 120 km. Now you can easily increase to 150+

[Lopatov]

Due to "rocketing". And it's pointless.

[Hermit21]

Well no. The usual CAS, it seems. And why is it pointless?

[Grigory_45]

Quote: Zaurbek

You can put a new barrel

then it’s not a new barrel, but a new gun. Increasing the firing range is not only a longer and more durable barrel, but also also a reinforced and larger charging chamber (for an enhanced charge), new recoil devices, etc.

As for me, upgrading the fire control system (systems for receiving data from a senior battery officer, automatically receiving and entering data for firing is a more accurate and faster hit of a target with less ammunition consumption, the ability of the machine to integrate into KP of various levels) is of much greater benefit. and ammunition loading systems (increase in rate of fire, reduction in the strength of the calculation)

[Zaurbek]

Enemies with 155 howitzers are already shooting at her level ..... who will Malka shoot at?

[Grigory_45]

Quote: Zaurbek

who will Malka shoot at?

honestly, I don’t see the tasks for this system in modern conditions. Rather, such tasks in which it would be indispensable or much more effective than existing systems (6-inch self-propelled howitzers and MLRS).

[Zaurbek]

Nobody is going to do their new ones ..... they are going to give them a decent power of their caliber

[barclay]

And nothing about increasing the firing range and rate of fire. It would also be nice for such a caliber a projectile of increased accuracy of the Krasnopol type.

[Aleks2048]

If a shell with a special warhead, then deviations at the point of impact (of course, within reasonable limits) do not matter.

[Zaurbek]

There are approaches to improve accuracy. Correction at the initial stage, inertial systems ....

[Zaurbek]

You can not sharpen the system only under the YaBCh ....

[Aleks2048]

You can not sharpen the system only under the YaBCh ....

Why? If there is no problem with ammunition, then actually why not use it?

[Lopatov]

Quote: Alex2048

If there is no problem with ammunition

Not the fact that "no problem"
I’m not sure that their technical condition was supported. After all, shells in caliber 152 are much better in terms of combat use.

[K-612-O]

There are no problems, they have long been replaced, and new ones, both 240mm and 203mm, are mass-produced.

[Lopatov]

Quote: K-612-O

There are no problems, they have long been replaced, and new ones, both 240mm and 203mm, are mass-produced.

What's the point?
The 152mm shell is much better. In terms of hiding preparation for striking.
Well, 240 nuclear mine is generally epic nonsense. With its range of application ...

[Zaurbek]

To make a whole system under the BCH? Which will not be used? what for? Now there are also 152mm shells with nuclear warheads. And their range is already comparable.

[Grigory_45]

Quote: Alex2048

accuracy always matters, even when using nuclear weapons. Accuracy helps reduce collateral damage. In addition, nuclear weapons tactical, low power.

[Berber]

There is no need for Krasnopl. Enough guidance from a satellite or UAV. All the advantage is the cheapness of ammunition. Effective as short-range tactical missiles and priced as conventional artillery shells.

[VicktorVR]

Unfortunately, the price is far from the usual shell. Electronics and other things become very expensive when you need to withstand the overload that occurs when firing a howitzer. The same for the MLRS missile will be 10 times cheaper, if not 100 times.

[Grigory_45]

Quote: BerBer

Enough satellite guidance

this is the cheapest way to put a GPS receiver in a shell. The accuracy, however, will not be very, and you need to know the coordinates of the target in advance.

Quote: BerBer

or UAV

laser-illuminated target? We get the same Krasnopol or Daredevil, only a larger caliber

True, such shells are more expensive than MLRS missiles (electronics must withstand wild overloads when fired)

[venik]

Quote: barclay

And nothing about increasing the firing range and rate of fire. It would also be nice for such a caliber a projectile of increased accuracy of the Krasnopol type.

=======
Range and rate of fire - WITHOUT change (the gun itself is the same). To increase the range, a new barrel is needed, and essentially a NEW gun and NEW ammunition. Expensive!!! The guidance and communication system has been improved, which in theory should increase the accuracy of shooting and the possibility of external target designation.
--------

Quote: barclay

It would also be nice for such a caliber an increased accuracy projectile of the Krasnopol type.

========
It is hardly advisable! "Malka" is good for shooting at LONG distances (up to 47,5 km) And for "Krasnopol", an EXTERNAL target illumination with a laser is required. WHO will do it? Send RDG to the rear of the enemy at a fairly large depth just for this? Doubtful something .....

[da Vinci]

Target designation - UAV for example.

[Mountain shooter]

A mighty cannon ... will not interfere in any way when "interacting" with "partners" ... Well, you won't spend Iskander on each target ... powerful flexible system of fire destruction. The projectile is more than a centner ... and the range of the active-reactive is almost 50 km. And he knows how to shoot nuclear shells ... "Long arm" division commander.

[Zaurbek]

Mighty, but 152-155mm systems already get it. You need to give her a "long" tool ... And you also need to develop ammunition for the MLRS systems of the Hurricane and Tornado, they just can occupy the niche of the Tochka-U system.

[knn54]

The firing range is up to 50 km and depends on the type of projectile. The rate of fire is 50 rounds per minute. Another 40 shells are transported in a separate machine.

According to Kiev, the most powerful army of Europa, too, put all its Peonies on the move. And even uses them from the age of 14.

[Scharnhorst]

Somehow I was not interested, but there was a premonition that such systems after the Cold War, Perestroika, Collapse of the Union, etc., etc., were cut on the basis of different Treaties and their own "Optimizations" of the Armed Forces. Thanks to the thrifty warrant officer for keeping the locker somewhere in the far corner! Cannons will come in handy for Ukraine, the Baltic extinctions, pshek ...

[Zaurbek]

Ukraine also has them.

Because, for example, the T-55 from KAZ in Ukraine was cut in due time. Under the control of the Americans and the money of the Americans.

[bayard]

There are, and before us, they often flew to us in Donetsk.

[Azazelo]

All the same, our strategists do not exclude the use of tactical nuclear weapons.

[Maxwrx]

Oh, I do not understand its meaning in the modern army. The speed of deployment and, most importantly, coagulation is too high, they will be destroyed after a couple of shots. Firing rate of 50 rounds per hour, firing range 47 km. 8 shells. Now compare with the coalition. In 152 mm, you can also put a tactical charge. More than 10 rounds per minute, firing range up to 80 km, deployment / folding speed of a minute, 70 shells, higher accuracy, lower collateral damage. Also cheaper several times. The time of fortifications was long gone, all the expatriates were either removed from service or put into storage, 203 mm - the caliber is excessive, of course, if you do not compensate)

And again, Malki’s transfer to the camp 3-5 minutes - this is the SPG, and we transferred our own for 5 - towed ....

Not the main probable opponent, but the natural one, who is actually fighting with us?
Yes, you can test "Caliber" on it, something else, like 101 ... but not cost-effectively, cast iron 500 each, Gradov rockets and artillery shells will grind them no worse, incl. and in hiding places.
This is in addition to the fact that no anti-aircraft / missile defense systems and other iron cumpoles can do anything against such a disc, and the satellite signal cannot be drowned out.

Good gun! A couple of shots end.

[Peter is not the first]
