The 2S31 consists of a 120mm 2A80 rifled gun-mortar mounted on the chassis of the BMP-3 infantry combat vehicle. It was developed by Joint Stock Venture "Plants of Motovilikha" (Russian: ОАО "Мотовилихинские заводы"). The 2S31's turret is equipped with digital automated fire control system, navigation system, and optical/electronic reconnaissance and target acquisition system. Its 2A80 gun-mortar is capable of launching a high-explosive mortar projectile with a maximum range of 18,000 metres. The vehicle is protected by a welded aluminium hull to protect against small arms fire and shrapnel. It can also fire armour-piercing projectiles that can penetrate up to 650mm of steel plate at ranges of up to a kilometre. A separate sighting system is used when engaging in direct fire mode.
