IJSC "Lotos" in the break between tests

24

The project of creating a promising self-propelled artillery gun (SAO) 2S42 "Lotos" has passed another important stage. Acceptance tests of the prototype were carried out and successfully completed. All the main characteristics and their compliance with the terms of reference have been confirmed. Now the prototype self-propelled gun can go to a new stage of testing, which brings the moment of adoption into service.


The official message


The completion of the first stage of testing was announced on November 25 by the press service of Rostec. The activities to check the experienced IJSC "Lotos" were carried out by the Central Research Institute of Precision Engineering and ended in success. Design documentation and prototype meet customer requirements.

The test program of the "Lotus" provided for verification of 57 parameters of various kinds. The characteristics were determined, all the main components and assemblies of the chassis, weapons, fire control system, etc. were checked. In total, during the acceptance tests, the experimental CAO passed 400 km along routes and fired 14 shots at targets.

It is noted that the finished armored vehicle corresponds to the technical specifications in terms of dimensions and weight. At the same time, it shows high running and fire characteristics. Provided with a high rate of fire and firing range.


The next stage of work is preliminary testing. They are scheduled to start in the coming weeks, before the end of the year. The timing of state tests, according to the results of which the CAO will be put into service, is not specified. Earlier it was stated that they will be held in 2019-2020, but by now the dates have shifted.

Recent past


The development of a promising CAO for the airborne forces began in 2016. At the same time, the Lotus project replaced the previously created Zauralets-D, which proposed a self-propelled gun of a different architecture with the use of other components. Materials on "Lotos" were first shown openly in 2017. Soon after that, the preparation of working design documentation was completed. At that time, it was planned to conduct state tests in 2019 and put the new CAO into series in 2020.

By the beginning of 2019, the Central Research Institute Tochmash built a prototype of the CAO 2S42 "Lotos", and soon its first images were published. The roll-out of the armored vehicle from the workshop for the first checks took place later, in early June. The fully loaded self-propelled gun has shown its ability to move, maneuver and aim weapons. A few weeks later, the experienced "Lotus" became an exhibit at the "Army-2019" exhibition.

At the beginning of August 2020, it became known about the launch of acceptance tests of an experienced CAO. The machine had to show its characteristics and capabilities in order to receive a positive conclusion of military acceptance. No details of these events were provided. At the same time, it can be assumed that it was precisely because of participation in the tests that the Lotus prototype did not make it to the Army-2020 forum. This year, the new CAO for the Airborne Forces was again demonstrated in the form of a model.


Together with the promising CAO, the new Zavet-D fire control vehicle was regularly mentioned. It was developed in parallel with "Lotus" and is also being tested. However, for obvious reasons, this model does not receive the same attention - although it is of great importance for the development of airborne artillery.

Near future


Already this year, the experienced CAO 2S42 should go to preliminary tests, after which state tests will take place. In the absence of serious difficulties, all these measures can be completed by the end of 2021, then the self-propelled gun can be adopted and put into series.

The product "Lotus" is created in the interests of the airborne troops. Now one of the main artillery means of the Airborne Forces is the 2S9 Nona-S airborne self-propelled gun. It is quite old and does not fully meet modern requirements. Launching the production of "Lotos" will allow starting the process of re-equipping the artillery units of the Airborne Forces.

According to open data, now the Russian Airborne Forces have at least 250 combat vehicles of the "Nona-S" type. The same number of new "Lotos" will allow maintaining quantitative indicators and at the same time obtaining an increase in quality - through the use of modern and fundamentally new components with higher characteristics.


Last year, it was announced that, together with the Airborne Forces, a new CAO would receive units of the Marine Corps, which also continue to operate systems of the 2S9 family. They have more than 40 tracked vehicles "Nona-S" and wheeled "Nona-SVK". Several dozen new "Lotos" will provide replacement of old equipment and increase the combat effectiveness of artillery units.

Thus, to update the park of self-propelled artillery guns of the two branches of the armed forces, at least 280-290 promising SAO 2S42 "Lotos" are required. The expected rate of mass production of such equipment has not yet been specified. However, it is obvious that the process of updating the artillery of the Airborne Forces and the MP will take a lot of time. It is very likely that the last batteries will be transferred to new technology only at the end of this decade or at the beginning of the next.

Obvious advantages


The Lotus project provided for a wide range of advantages over the older technology. Measures have been taken to improve combat, technical and operational characteristics. Due to this, the 2S42 product is more interesting for the troops - with an eye to the long-term perspective.

One of the main advantages of "Lotus" and "Covenant-D" is the use of the mastered platform. SAO is built on the chassis of the BMD-4M landing vehicle, and the control vehicle is made in the body of the BTR-MDM armored personnel carrier. This greatly simplifies and reduces the cost of the parallel operation of several types of combat vehicles. In addition, all samples on a common chassis have similar tactical and technical characteristics, they can be parachuted, etc.


The 2S42 carries a new 120mm smoothbore gun, supplemented with automated fire preparation and fire control equipment. When using existing ammunition, the gun is capable of firing at a range of 13 km. A new active-rocket projectile with the "Glissade" code is being developed, increasing the firing range to 25 km. Other new ammunition is expected to increase the combat qualities of self-propelled guns.

The Lotus uses a modern digital sighting system with all the necessary devices for direct fire or from closed positions. The self-propelled gun is included in the control system of the tactical link of the Airborne Forces and can exchange data with other machines. Combat vehicles must interact with the Zavet-D command vehicle, which carries all the necessary data processing and command generation facilities and also interacts with the command and control systems.

Pending rearmament


It is easy to see that the process of rearming the airborne artillery was noticeably delayed. The project "Zauralets-D" was recognized as unsuccessful and was replaced by "Lotus", built on different ideas. The development of the CAO 2S42 "Lotos" took longer than originally planned, and tests are now underway - although it was previously planned to start the series in 2020.

Nevertheless, the work continues and is nearing completion. Despite all the delays and difficulties, in the coming years, the industry will be able to launch the production of the 2S42 self-propelled gun and a compatible control vehicle, and the troops will begin to master this technology. The modernization of the artillery of the airborne and coastal forces has been postponed but not canceled.

    Compared to the Nona, purely visually, with the same caliber, but with a significantly larger barrel elongation, the new SPG is perceived as a light tank.
    And also, the large length of the trunk also speaks of a different ballistics than that of its predecessor, especially since the barrel is without rifling.

        Nona was grooved (the projectile had grooves initially). About the tool of the Lotus in Vick they write that without rifling. And how really?

        The tasks are the same, but the range is more, the LMS is newer, and so on.
        Tool pointing angles:
        - horizontally - 360 degrees.
        - vertically - from -4 to +80 deg.

          First, there was a French 120-mm mortar of a special design: an elongated barrel, rifling, special artillery shells. As a result, we got greater accuracy. greater range, greater action at the target of the ammunition.
          Nona was made according to the same principle, only it was initially decided to put it on a self-propelled chassis (from an armored personnel carrier), and call the improved type artillery shells artillery shells, while maintaining the ability to fire conventional artillery shells.
          The main essence of this whole direction, i.e. conceptual feature and consists in an elongated rifled barrel and artillery shells (artillery shells) of an improved design. It goes without saying that Nona, Vienna, Zauralets-D and the current Lotus-D have an elongated rifled barrel and appropriate ammunition.

          Zauralets-D was made as a CAO of a family of vehicles based on the BMD-3 chassis. Because The BMD-3 chassis is a thing of the past, then, of course, for the purpose of unification, the new CAO Lotus began to be made on the BMD-4M chassis.

        Nona could really be used as a howitzer and as a mortar and as a cannon. The Lotus, apparently, does not have such unique versatility.

      Do we have an ATGM in caliber 120 mm?
      And the rifled barrel ...
      How are we doing with cormines in 120mm caliber?

      The versatile Lotus cannon can use a wide range of 120mm ammunition, including 120mm rounds and mines produced in other countries. This nomenclature also includes the KM-8 Gran 'guided mines and the Kitolov-2 shells, which, “when performing combat missions, make it possible to reduce: the number of weapons involved - two to three times; projectile consumption - not less than 50 times; the cost of completing a combat mission is five to ten times. "

        This nomenclature also includes the KM-8 "Gran" guided mines and the "Kitolov-2" shells.

        Gan and "Kitolov - 2" are the only controllable ones in the ammunition load today. Moreover, the Tula people promise to finish the Kitolov for GLONASS correction.
        But the paratroopers fired only twice with the shell itself.
        And in general - there is a muddy topic, because, as I already wrote, "Kitolov - 2M" - in caliber 122 mm. They want to export it and the Verge, not to the Airborne Forces.

      For a promising self-propelled artillery gun (SAO) of the Airborne Forces "Lotos", a new guided active-reactive gliding projectile (code "Glissade") with a firing range to 25 km, said at the forum "Army-2019" the chief designer of "Lotus" Veniamin Schastlivtsev.

        When developing "Glissade" it is proposed to use the developments obtained earlier when creating new ammunition for the promising 152-mm self-propelled artillery system "Coalition".
        “At the same time, we assume that this work should be developed on the basis of a homing head for a long-range ammunition, which is now being developed in 152 mm caliber for the Coalition-BP,” the designer noted.
        According to him, at one time, exactly the same decision was made when developing the previous generation of high-precision weapons.

        Excuse me, so in what caliber ACS do you need for the Airborne Forces?

          All I can answer is that there were 2 developments of 120 mm and 152 mm.
          As far as I understand, 152 mm is considered inappropriate. hi

    After reading the news, only one question arises - it was already asked before. And it was impossible to lighten the weight (or what they need to modernize) the existing airborne squad (no ammunition inside, only IL-76 and higher because it is heavy) under the requirements of the landing troops! self-propelled gun 2s31 Vienna?
    Or, as always, the money pilling according to the scheme - new terms of reference -> prototypes that have no analogues -> expensive, something simpler is needed, we will modernize or repair existing copies, and the sawn money will be successfully mastered by the right people.

      Could it be possible to think about the fact that the 2S31 was not originally intended for the Airborne Forces and the MP, as it was built on the basis of the BMP-3? In the landing, they intentionally support unification based on BMD. Or, as always, the gundezh according to the scheme: wrote about the pile of other people's money → thought (no).

        > unification based on BMD
        Read the wiki about the BMD-4, on the basis of which it was released. I also quote from memory the data from the magazine # the unification of the nodes between the BMD-4 and the BMP-3 has reached (depending on the modification) from 45 to 65%, due to this, the developer accounts that it will be possible to reduce the price. (But still there was a scandal: the BMD-4 in the trial batch was more expensive than the tank, which is why there is confusion with 4, there are 2 incompatible modifications because the production was given to another plant)
        So the question is interesting and open.
