The 152-mm 2S35-1 Koalitsia-SV-Ksh Self-Propelled Howitzer is a version of the 2C35 Koalitsia-SV tracked SPH, but on a wheeled chassis. The developer is Central Research Institute "Burevestnik". It is known about the manufacture and testing of a prototype.

As a basic chassis of the 2S35-1 is used the all-wheel drive truck KamAZ-6560 8x8. The main modifications of the chassis touched the reinforcement of the frame of the truck.

Armament of the 2S35-1 is similar to 2C35 (2A88 152-mm howitzer and Kord 12.7-mm machine gun). Like the basic automatic control system 2S35, the self-propelled howitzer 2S35-1 has a remote-controlled turret. The crew of the vehicle is placed in the armored cab of the chassis.

Koalitsia-SV SPH is a robotic complex: fire control is carried out remotely, there is the possibility of automatic loading of a modular propellant charge, and all operations are displayed on the displays of a single information and command unit. The firing range of the SPH reaches 70 km, the rate of fire is 16 rounds per minute, the angles of horizontal fire are from -90° upto +90°, direct fire is posible.

During the fire the gun leans on four retractable outriggers with a hydraulic drive. The deployment time in combat position is up to one and a half minutes.
