   The Koalitsiya-SV KSh is a new Russian self-propelled howitzer. It uses the ordnance of the 2S35 Koalitsiya-SV, but is based on 8x8 military truck chassis. A prototype of this artillery system was ready by 2013. Public pictures of this artillery system first appeared in 2017. The Koalitsiya-SV KSh is a very capable artillery system.

   Since the early 1980s Soviets developed a 152 mm howitzer, based on an 8x8 wheeled chassis. It was known as the 2S21 Msta-K. A couple of prototypes were built, however this artillery system never reached production and the program was cancelled in 1987. It was a failure mainly because at that time Soviets had no suitable trucks to carry this howitzer, that would have sufficient payload capacity, be powerful enough and could withstand the violent recoil. The new 2S35-1 Koalitsiya-SV KSh can be seen as an evolution of the 2S21 Msta-K.

   The 2S35-1 Koalitsiya-SV KSh utilizes the unmanned turret with 152 mm ordnance of the 2S35 Koalisiya-SV self-propelled howitzer. It is based on a modified KamAZ-6560 military truck with 8x8 configuration. This artillery system can be seen as a less expensive and more mobile alternative to the tracked version. Though it looses to tracked version in terms of off-road mobility and armor protection. It is planned that this truck-mounted howitzer will be mainly used by units, that are equipped with wheeled combat vehicles, while the tracked version will be used by units equipped with tracked combat vehicles.

   Unmanned turret is fitted with a fully automated ammunition loading and handling system. This howitzer utilizes 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. It has a maximum range of 70 km. The Koalitsiya-SV KSh is also capable of firing older Krasnopol precision guided munitions with a range of 20 km.

   Maximum rate of fire is around 8 rounds per minute. It seems that the Koalitsiya-SV KSh is capable of Multiple-Round Simultaneous Impact (MRSI) firing. It can launch several shells with different trajectories, that would land on the target simultaneously. Such way of firing is very efficient. This artillery system carries impressive onboard ammunition supply of around 60 to 70 rounds.

   The Koalitsiya-SV KSh has a brief reaction time. It can be emplaced within 1.5 minutes. It takes even less time to leave the firing position. Such brief redeployment time allows to avoid counter-battery fire.

   This truck-mounted howitzer has an automatic targeting and charge selection system.

   This artillery system is operated by a crew of only 3 soldiers. High level of automation allowed to have such a small crew. Crew operates this howitzer remotely from the truck cabin. It seems that this vehicle can be fitted with an armored cabin. It would provide protection for the crew against small arms fire and artillery shell splinters.

   There is a remotely-operated station with a 12.7-mm machine gun for self-defense.

   This artillery system is powered by a KamAZ-740.35-400 turbocharged diesel engine, developing 400 hp. Vehicle is fitted with a central tyre inflation system, which improves mobility over difficult terrain, such as sand, snow and mud. This vehicle can travel off-road.

   This artillery system is supported by a reloading vehicle, based on a similar 8x8 military truck chassis. It carries ammunition and assists reloading of the truck-mounted howitzer. Also this artillery system has a built-in ammunition reloading system at the rear of the turret that allows to load ammunition directly from trucks.
