Although Koalitsiya-SV was slated to be based on the Armata universal chassis, the pre-production vehicles appear based on a modified T-72/90 chassis. The general layout and roadwheels appears to be identical to those on the T-72/90 chassis, although the front of the chassis has been heavily modified to create positions for the commander and gunner on either side of the driver. Unlike on Armata, where the driver is located on the right side of the vehicle, the driver on Koalitsiya is located in the centre of the vehicle (as seen in the T-72/90 and 2S19).
According to Georgy Zakamennih, chief director of TsNII Burevestnik, the developer of the 2S35, Coalition-SV has a maximum range of 70 km when firing advanced shells. He added that its ammunition load is larger than Western analogues. There is a unified command-and-control panel on which all the actions are displayed. The system's pneumatic loader is billed as increasing Coalition-SV's rate of fire. 2S35 can automatically choose the appropriate type of shell and fire it. Coalition-SV is therefore not a classic self-propelled gun but an innovative robotised complex, autonomous to a high extent, he said.
