In the interests of the artillery of the ground forces, a promising 152-mm self-propelled artillery mount 2S35 "Coalition-SV" was developed. Over the past few years, this product has been tested, and such activities are nearing completion. In addition, it became known about the launch of the production of self-propelled guns of this type, as well as the transport and loading machines intended for them.
At the test stage
Recall that the project of self-propelled guns "Coalition-SV" was developed from the middle of the XNUMXs. The lead developer was the Nizhny Novgorod Central Research Institute "Petrel" from the NPK "Uralvagonzavod" of the state corporation "Rostec". At the beginning of the tenth years, the appearance of the future self-propelled gun was formed, the design was completed and the construction of experimental equipment began.
According to known data, the first 2S35 prototypes were built in 2013-14. and at the same time they went to the test on May 9, 2015, this technique was first shown to the public. Over the next years, the Coalition-SV prototypes worked at the test site, confirming the design characteristics and demonstrating new capabilities. Due to the complexity of the project and the tasks set, the tests are still ongoing.
The self-propelled guns "Coalition-SV" have already shown their main capabilities, and also demonstrated superiority over existing artillery systems. So, in 2019, the self-propelled gun fired at a distance of 80 km - at the moment this is a record for domestic 152-mm guns. At the same time, it was reported that the "flurry of fire" mode was being worked out, which made it possible to increase the fire impact on the enemy and reduce the risks for self-propelled guns.

The assembly of the Coalition-SV was entrusted to the Uraltransmash enterprise (Yekaterinburg). At the end of 2019, it announced the completion of the construction of an experimental batch, which was soon going to be sent to the troops. In addition, the preparation of a full-fledged serial production has started.
Based on the results of these events, in August 2021, at the Army-2021 forum, the Ministry of Defense issued an order to Uraltransmash for the mass production of new self-propelled guns. The quantity and cost of equipment were not specified at that time. It is curious that by the time the first serial contract appeared, self-propelled guns were still at the testing stage.
Actual plans
Recently, the current state of affairs in the Coalition-SV project and the developers' plans for the near future became known. August 10 RIA News published an interview with the Deputy General Director of Rostec Vladimir Artyakov. The topic of conversation was current projects and the exposition of the state corporation at the future Army-2023 forum.
V. Artyakov said that tests of the 2S35 product are ongoing, and they are planned to be completed by the end of the year. At the same time, serial production has already been mastered. Both self-propelled guns and transport-loading vehicles for them are being built. The volumes and rates of such construction, for obvious reasons, are not named.

From such a statement it follows that the new self-propelled guns will enter service with the ground forces in the near future. At the same time, a contract for mass production of equipment is already in place and is being implemented. This means that the rearmament of combat units will also be able to begin in the foreseeable future.
New solutions
Within the framework of the Coalition-SV project, an ACS of a traditional appearance was developed, designed to solve a well-known range of fire missions. At the same time, the 2S35 design uses a number of new components and solutions, due to which a significant increase in tactical, technical and combat characteristics is ensured. The resulting self-propelled gun has important advantages over modern models of its class.
SAU 2S35 is an armored combat vehicle on a tracked chassis with a turret carrying weapons. The modified chassis is used as the basis for the "Coalition-SV" tank T-90, which gives the necessary characteristics of mobility and patency.
For self-propelled guns, an original tower with an uninhabited fighting compartment was developed. Inside it are a gun mount, mechanized stowage of ammunition, automatic loading and remotely controlled guidance drives. Outside the tower there is a combat module with a machine gun for self-defense and smoke grenade launchers.

The 2S35 product is equipped with a 152 mm 2A88 rifled howitzer. This gun has a barrel length of 52 klb with a developed muzzle brake and ejector; shutter type unknown. For the first time in the domestic ground artillery, a separate loading principle with a modular propellant charge is used. Such a charge consists of several cartridge modules, the number of which may vary depending on the required energy of the shot. The supply of shells and modules into the chamber is carried out automatically. The shot is made due to the original system of microwave charge initiation.
Carried ammunition - 70 shots. "Coalition-SV" can use all domestic projectiles of 152 mm caliber, including guided ones. At the same time, an increase in the firing range was ensured in comparison with other self-propelled guns, and the accuracy of hits was also improved.
"Coalition-SV" is equipped with a modern digital fire control system with the necessary components and functions. Topographic location and calculation of data for firing are provided, several modes of firing are provided. It is assumed that there is a radar on board the self-propelled guns that tracks the trajectory of the projectile and helps to correct the fire.
The crew of the self-propelled guns consists of three people - commander, driver and gunner. All of them are placed in a common compartment inside the case. The systems and mechanisms of the fighting compartment are controlled remotely.

Together with the 2S35 self-propelled gun, the unit will receive the 2F66-1 transport and loading vehicle, made on the KamAZ serial chassis. The TZM van houses mechanized stowage, as well as means for moving projectiles and charge modules. With the help of a retractable conveyor, the TZM transfers the components of the shots to the self-propelled gun. The 2F66-1 machine can work with different ammunition in caliber from 120 to 152 mm. In the latter case, she carries 92 shots.
Future opportunities
The promising self-propelled guns 2S35 "Coalition-SV" in its design differs significantly from existing domestic 152-mm systems. Due to such differences, a significant increase in combat and other characteristics is provided, as well as the potential for further development is created.
The growth of combat performance is ensured, first of all, by the new 2A88 gun and its ammunition. This product is characterized by an increased barrel length, which allows more efficient use of the energy of the propellant charge. In this case, the gun during firing is fully serviced by automation.
A real technological breakthrough is the use of a modular propellant charge. Variable charges are well mastered in our artillery, however, a modern system of modules allows you to optimize loading processes and provides other advantages. Thanks to this, the tool becomes a more flexible tool for solving all the intended tasks. Also of interest is a microwave charge initiation system. It provides simultaneous ignition throughout the entire volume of the module, which makes it possible to optimize combustion and increase energy parameters.

The new SLA for the "Coalition-SV" solves all the tasks of preparing for firing, adjusting fire, etc. In addition, it has improved capabilities for interaction with other ACS and control structures. In fact, ACS 2S35 is adapted to work in network-centric circuits with the corresponding capabilities and advantages.
With all this, the project has the potential for further development. In particular, the possibility of transferring the 2S35 fighting compartment to another chassis has already been shown. A self-propelled gun variant was tested on a KamAZ vehicle. The possibility of using the Armata tracked platform in the future is also mentioned. Another area of development could be the creation of new shells.
On the eve of rearmament
Thus, the new product 2S35 "Coalition-SV" compares favorably with the 152-mm self-propelled artillery systems available in our army and therefore is of great interest. In all the main parameters, the 2S35 is superior to the available 2S3 Gvozdika and 2S19 Msta-S vehicles, which have guns of the same caliber. Interest in a new model two years ago led to the emergence of a contract for mass production.
According to the latest news, the tests of the "Coalition-SV" are already being completed. In addition, the industry has established mass production of such equipment. All this suggests that the wait is coming to an end - in the near future the new self-propelled guns will enter service and complement the existing self-propelled guns.
