Project SAO 2S42 "Lotos": two prototypes for state tests
The first prototype of the SAO "Lotos" on trials
Currently, tests and fine-tuning of the promising airborne self-propelled artillery gun 2S42 "Lotos" are being carried out. So far, one prototype machine is participating in these events, but a second prototype will join it in the foreseeable future. As reported, the presence of two self-propelled guns will allow you to fully test and work out all the new features of technology.
During the test
The first experimental "Lotus" was built a few years ago. In November 2020, he passed acceptance tests, and in August 2022, they announced the completion of preliminary tests. At that time, work was underway to eliminate the identified deficiencies and prepare for the next stage of inspections. In addition, in the 3rd quarter of the next 2023, they planned to start state tests.
October 25 RIA News revealed new details of ongoing work on Lotus and plans for the near future. Information of this kind was provided by an informed source in an unnamed structure.
According to the source, the first experimental CAO 2S42 is now in the third stage of work. Correction of the shortcomings revealed during the previous tests is carried out. These or other shortcomings are present in the design of the chassis, on-board electronic equipment and automatic loader. The nature of such problems and how to eliminate them are not given.
Experienced CAO at the forum "Army"
The source also said that the industry has already begun construction of the second prototype, which is necessary for the next stage of inspections. With the help of two prototypes, the customer will be able to conduct full-fledged state tests. First of all, it will be possible to check the interaction of self-propelled guns during joint combat work and the performance of tasks.
The source mentions that a second Lotus is being built for use in government trials. These activities, according to current plans, will begin at the end of 2023. Whether they will have time to assemble an experienced self-propelled gun by this time is not specified.
The deadlines for completing state tests and carrying out the following procedures and activities are not reported again. Nevertheless, already known and new information suggests that the Lotos SAO will be put into service no earlier than 2024. In the coming years, serial production of equipment for delivery to the army will begin.
New solutions
The promising SAO 2S42 Lotos is being created at TSNIITOCHMASH (part of the Kalashnikov concern) in the interests of the airborne troops. In the foreseeable future, such equipment will go into parts and begin to replace the existing self-propelled guns of the 2S9 Nona-S line. The new project uses and develops some of the ideas taken from Nona. This provides for the widespread introduction of new solutions and components that will provide an increase in performance and provide new opportunities.
So, in order to unify the equipment of the Airborne Forces, a promising CAO is being built on the basis of a modified chassis of the BMD-4M landing vehicle. Such a chassis is distinguished by an elongated body and an additional pair of road wheels; it also provides for the restructuring of internal volumes and equipment. The driving characteristics of the 2S42 remain at the level of the BMD-4M. The combat weight is 18 tons, thanks to which the self-propelled gun can swim and parachute.
The fighting compartment of the new development is mounted on the chassis. It is built around a 120-mm "universal" smooth-bore gun that performs the functions of a gun, howitzer and mortar. There is an automatic loader compatible with various types of ammunition. The rate of fire is up to 8 rds / min. The range of fire, depending on the ammunition, is 13 km. The main gun is complemented by a remote-controlled weapon station with a 7,62 mm machine gun.
It is known that a new fire control system has been created for the Lotus, which makes it possible to realize the potential of the 120-mm gun. It includes sights of various types, incl. commander's panoramic instrument, ballistic computer, weather sensors, crew workstations, etc. The JMA is also responsible for the use of the DBMS.
SAO 2S42 is being developed for the Airborne Forces and should work in the communications circuits of this type of troops. To do this, the machine receives communication equipment and other devices compatible with the Andromeda automated command and control system. Such equipment will allow the self-propelled gun and its crew to exchange data with other gunners and the unit commander, receive target designation, etc. Due to this, the effective combat work of both individual SAOs and entire units will be ensured.
In the next stage
To date, the only "Lotus" has passed several stages of testing, the purpose of which was to check the main systems and assemblies. So, the car showed the required driving characteristics and mobility on land and on water. In addition, the firing qualities of the new weapons complex were demonstrated. In general, the experimental CAO coped with the tests, although some shortcomings were identified.
The new self-propelled gun will be used by the artillery of the Airborne Forces as part of fire platoons and batteries. For this reason, as part of the tests, it is necessary to work out the issues of joint operation of several combat vehicles. In addition, it is necessary to check the interaction of such units with the existing automated control system. It is obvious that it will simply not be possible to conduct such tests using only one experienced Lotus. It was in connection with this that TsNIITOCHMASH began the construction of the second prototype.
As reported, the first prototype is now being finalized based on the results of previous tests. The second machine should immediately be built according to an improved version of the project. Accordingly, next year two SAOs of the final form will go to state tests, and in this form they will show the full potential of the 2S42 project in its final version.
Predictable future
SAO "Lotos" has not yet passed all the stages of testing, but the course of further events is already clear. So, in about a year, a second prototype will appear, made according to an updated project. Together with the existing machine, he will go to the training ground, and over the next few months, the equipment will again work on the tracks and shooting ranges.
Previous events give cause for optimism and allow us to avoid negative forecasts. Apparently, already in 2024, two "Lotus" will confirm the design characteristics, and a new model of armored vehicles will receive recommendations for adoption and for the launch of mass production.
In this case, the first 2S42 products can be manufactured and transferred to the troops as early as the middle of this decade. It will take a few more years to produce the required amount of equipment and replace obsolete vehicles in parts of the Airborne Forces. How long this process will continue, and how many SAOs the armed forces will receive, has not yet been reported.
Having received the new Lotus guns, the airborne artillery will retain the existing fire capabilities, which are now provided by the Nona-S self-propelled guns. Such vehicles will be able to accompany airborne units and support them with direct fire or fire from closed positions using shells or mines. At the same time, a new weapon system based on a modern weapon and an SLA, coupled with an up-to-date automated control system, will improve the range and accuracy of fire.
The tracked platform "Lotus" shows high technical characteristics, and is also unified with the new generation of airborne armored vehicles. In addition, the self-propelled guns of the new construction will have a full resource and will be able to remain in service for the next few decades.
Reasons for optimism
Thus, work on a promising self-propelled gun for the Airborne Forces continues and solves new problems. Currently, the existing experimental Lotus is being finalized and the second prototype is being built at the same time. In about a year, two cars will enter the state tests, and over the next months the fate of the 2S42 project will be decided.
So far, it cannot be ruled out that due to certain events and factors, the Lotus program schedule will be adjusted, and specific events will occur later than expected. Nevertheless, the general course of the project is obvious and allows making optimistic forecasts.
