The "Elder Sister" of the "Coalition of SV" SAU 2S3M2 possesses a "developed intelligence"

The "Elder Sister" of the "Coalition of SV" SAU 2S3M2 possesses a "developed intelligence"

Self-propelled artillery mounts 2 S3 "Acacia" have been in service with the Soviet and then the Russian army for 44 years. They will be the first to be replaced by the new Coalition SV 2S35 super self-propelled guns. The latest to retire will be the modernized 2S3M2 self-propelled guns, which, in terms of their combat intelligence, can compete with many foreign artillery systems.

Externally updated "Acacia" looks almost the same as its older versions. This is all the same 152-mm howitzer 2А33М, the range of which with a conventional high-explosive fragmentation projectile reaches 17,4 km, and active-reactive ammunition - up to 20,5 km. Ammunition - 46 shots.

The rate of fire is up to 4 shots per minute. Reservations - up to 30 mm. Engine power - 520 HP Maximum speed - up to 60 km / h. Power reserve - up to 500 km. Its weight is 27,5 tons. Crew: 4 man.

The difference is in the well-developed “intellect” hidden inside the car.
These peculiar "electronic brains" self-propelled guns were called ASUNO-automated guidance and fire control system.

This system, equipped with a digital ballistic computer, provides unprecedented automatic guidance at any time of the day. It enables the processing and storage of information on 10 fire missions, as well as the transfer of reports to the control machine. There is a modern satellite navigation system. The presence of a special antenna in the back of the tower indicates its presence.

Vehicles can arbitrarily disperse into a firing position, which significantly removes the risk of being hit. ASUNO devices are available both for the commander of the vehicle, and for the gunner and loader.

Due to the presence of ASUNO, the old woman "Acacia" got a second life. With its help, the self-propelled gun not only surpasses, as they say, "on the head" similar machines that are in the armies of the countries of the former post-Soviet space, but can argue on a number of characteristics even with modern NATO ACS.

    "The old woman" is very impressive! Somehow, by chance, on mushroom and berry business, I ended up at the training ground
    and all of a sudden, a disguised self-propelled gun shot at the command of the TsU. Horror! A shell whistling, tearing
    air rushed into the distance!

      Good old self-propelled guns Acacia. Simple and reliable. Of course, in terms of firing range it is inferior to the developments of leading countries, but such modernization will increase the capabilities and extend the operation of vehicles in the troops until being replaced by the Coalition.

        unprecedented guidance

        That is, do not look to pretsel?

    I had the honor of serving as a gun commander on this system in 88-90. How many years have passed, and I still remember "Acacia" with warmth and tenderness!

    I don’t understand in any way. The Americans have repeatedly upgraded their M-109. The length of the barrel was increased from the initial 23 to the current 39 calibers (range, respectively). And what prevented the USSR and now Russia from doing the same? Ultimate design or the depravity of the military-industrial complex? I am inclined to the second. Who is in the know - clarify the situation. Regards to the community.

      when creating any machine, the threshold of modernization is laid in it. but there comes a time when it’s better to do new, thereby give impetus to development than to improve the old

      If you increase the length of the barrel of Acacia (28 calibers) to over 40 (more precisely 47), you get Msta. request with the corresponding muzzle energy, initial velocity and firing range.
      Is it advisable to make a lightweight Mstu from Acacia?
      Or is it easier than Acacia to regimental, brigade artillery, Mstu and Coalition to a division, army?
      The goals are not only far, but also relatively close to being in the war.

      The Poles want to catch up, in August they riveted as many as 2 models with 52 caliber 155 mm.

      How else will they test?

        That's right!
        Indeed, simply increasing the length of the barrel in order to increase the initial velocity of the projectile and, as a consequence of the firing range, is too difficult from an engineering point of view. wink
        It is necessary that such a trunk was strong enough and tough. Otherwise there will be no accuracy. Both the resource and effective POUs (anti-recoil devices), and the base must withstand increased loads both during firing and during the march.
        Yes, and competition with powerful MLRS and OTRK (and bomber and attack aircraft smile) is unlikely to be useful.
        And then there will be a kind of expensive and complex hippopotamus, like the German "Ferdinant" - "Elephanta", itself clumsy and vulnerable.

    I served in 1974 as a senior officer in the 2S3M battery in Czechoslovakia. Good car!!! And most importantly - simple! An attorney, or as they are also called "partisan", who saw her for the first time, can be trained in half a day. The 2S3M2 certainly improves both attachment and fire control, and this all together gives greater mobility, which means survival in modern combat conditions. Here are just the supply of ammunition and, in general, logistic support will become one of the first places.

      This is the main advantage that was, with the introduction of modern technology, is becoming a thing of the past. And in the event of a big war, it will become even that "headache".

    I enjoyed reading the article. I am glad that Russian artillery systems remain at their best. And how they fired happened to see repeatedly in the immediate vicinity ... good

      ... if only not in the zone of projectile damage from this installation, namesake!
      As in other Russian others!

    Let's see how all this modernization will end.
    He served as a mechanic in 2С3 - almost half of them that we had in 2 divisions were not away. So let's see ...

      And for what reason did they not go?

        Hard to say. If technically, somewhere the main clutch was killed9 most of the cars), somewhere there was not enough of all sorts of little things (necessary to "revive"), which were taken from neighboring cars (if any). Where the weapon did not go down / rise, where the wedge-bolt just lay in the breech.
        And if not technically - the usual sloppiness No.
