Serial production of the Motovilikha 120mm SP-120 (2S31) Vena self-propelled gun/mortar is ongoing for Russian domestic requirements. The Russian Army intends to employ the tracked 2S31 as its primary 120mm self-propelled gun/mortar system, gradually replacing the older tracked 120mm SO-120 (2S9) self-propelled gun/mortar system.
