   The 2S35 Koalitsiya-SV (coalition) is a new Russian self-propelled howitzer. It is a successor to the 2S19 Msta-S. It is also intended to replace ageing Russian 152 mm artillery systems. Currently it is one of the most capable howitzers in the world. The first demonstrator was completed in 2006. This unique self-propelled howitzer had two 152 mm guns. It used a number of components from the previous 2S19 Msta-S. The twin-barrel Koalitsiya-SV demonstrator had a higher rate of fire than current artillery systems. It could fire at a rate of around 16 rounds per minute. This demonstrator had a fully-automatic ammunition loading and handling systems. Two guns offered a number of other advantages comparing with traditional self-propelled howitzers. Such artillery system was more reliable as both guns had associated autoloaders and if one of them failed, another could keep on firing. This self-propelled howitzer used both guns in quick succession, so the guns would not overheat and had twice longer service life. This demonstrator of the Koalitsiya-SV could load both guns at any inclination angles. This self-propelled howitzer was capable of multiple round simultaneous impact firing. It could also launch two precision-guided rounds, that will hit two different targets simultaneously. The demonstrator had a crew of 5, however it was planned that production Koalitsiya-SV would have a high level of automation. Demonstrator of the Koalitsiya-SV used a modified Msta-S chassis. However this project was cancelled. For some reason twin-barrel design was abandoned.

   In 2013 a new prototype of the Koalitsiya-SV was completed. It had a different design and only one gun. Initial production of the 2S35 Koalitsiya-SV commenced in 2014. A first batch of 12 pre-production artillery systems was delivered to the Russian Army in 2015. It was first publicly revealed during the same year. However these were early prototypes. By 2019 this artillery system was still trialed by its manufacturer. Most likely that there is still a number of technical issues with this new artillery system. It is planned that Russian military trials will be completed in 2022. So full-rate production will begin not earlier than 2022-2023.

   Even though the Koalitsiya-SV resembles the older 2S19 Msta-S, it is a totally different artillery system. It has unmanned turret and is armed with a 152 mm gun. It has a fully automated ammunition loading and handling system. It utilizes a modular charge system. This artillery system can fire a wide range of munitions, including standard and rocket-assisted HE-FRAG projectiles, cluster projectiles with anti-tank submunitions, jammer carrying projectiles. Range of fire with standard projectile is around 30 km and around 40 km with rocket-assisted projectile.

    A new long-range precision-guided round has been developed in Russia. It has a maximum range of 70 km and high level of accuracy. The Koalitsiya-SV It is also capable of firing older Krasnopol laser-guided munitions with a maximum range of 20-25 km.

   For export customers the 2S35 Koalitsiya-SV can be fitted with a 155 mm gun, compatible with standard NATO ammunition.

   Maximum rate of fire is around 8 rounds per minute. It seems that the Koalitsiya-SV is capable of multiple round simultaneous impact firing.

   This artillery system carries impressive onboard ammunition supply of around 60 to 70 rounds. It has an ammunition reloading system at the rear of the turret that is used to load ammunition directly from resupply trucks.

   The Koalitsiya-SV has an automatic targeting and charge selection system.

   Vehicle has a remotely controlled weapon station, armed with a 12.7 mm machine gun. It can be used for self-defense against air and ground targets.

   The Koalitsiya-SV has a high level of automation. It allowed to reduce the crew. This artillery system is operated by a crew of only three men, including commander gunner and driver. Crewmembers are located in a well protected compartment at the front of the hull.

   Armor of this vehicle protects the crew against small arms fire and artillery shell splinters. Vehicle is also fitted with NBC protection and automatic fire suppression systems.

   The Koalitsiya-SV uses new tracked chassis. It uses components of the T-90 main battle tank. General layout of the chassis resembles that of the T-90, but the front is heavily modified to accommodate the crew. It is likely to be powered by a turbocharged diesel engine, developing around 1 000 hp.

   Vehicle has a built-in self-entrenching blade and can dig itself a trench within 12-40 minutes, depending on the ground type.

   This artillery system is supported by a reloading vehicle, based on 8x8 military truck chassis. It carries ammunition for the Koalitsiya-SV.

 

Variants

 

   2S35-1 Koalitsiya-SV KSh is a wheeled version, based on a KamAZ high mobility truck with 8x8 configuration. It can be seen as a less expensive and more mobile alternative to the tracked version. This truck-mounted howitzer will be mainly used by motorized infantry units, that are equipped with wheeled armored vehicles.
