One of the new developments of OAO "MZ" is 2S31 Vena self-propelled guns, "Vienna", created on the basis of infantry fighting vehicle BMP-3. On the field of self-propelled gun battle in the first place should support fire infantry battalion, moving on the BMP-3. The layout of the machine is quite traditional scheme. In the fore part of the housing along its longitudinal axis is driving compartment, where is the driver's workplace. The middle part of the body and the armored turret holds the fighting compartment.

At the stern is the engine-transmission department. The hull and turret are welded from sheets of self-propelled armor, protects the crew from small arms bullets and shrapnel of artillery shells and mines. It equipped with a self-propelled ten V-shaped cylinder diesel engine with liquid cooling UTD-29, It reaches capacity 500 l. from. Hydromechanical transmission has a power take-off on the water jets.

"Vienna" is mounted on a modified chassis BMP-3. Individual hydropneumatic suspension features a large dynamic swing of rollers, paired with external cushioning in the form of rubber bands. On each side of the support are arranged in six or three support rollers. Additional hydraulic shock absorbers attached to suspension assemblies of the first two and last rollers. The drive wheels are rear location. Electromechanical remote controlled track tensioning mechanism is controlled from a place of the driver. caterpillar steel, Melkozvenchataya with rubber mount. Due to such a device chassis car moves smoothly both on the highway, and cross country. It easily overcomes the vertical walls, high reaching 0,8 m, and wide moats 2,5 m. The "Vienna" fighting compartment so designed, that can be placed on other types of chassis - tracked or wheeled. Sometimes as a wheeled chassis may be used floating BTR-80.

2C31 "Vienna" is the floating car and can reach speeds of 10 kmh, that is carried out by means of two single-stage axial screw type water jets. As the main arms for self-propelled protrudes 120mm rifled cannon, being upgraded version 2A51 self-propelled 2S9. It includes a rifled barrel with a combined semi-automatic breech, cradle with fencing, recoil device and a lifting mechanism sectored. From the base model gun in the first place characterized by long barrel, It had a positive impact on the firing range when using the same ammunition. Besides, it is equipped with a pneumatic rammer and a system of forced purge the barrel after firing. Guidance tools made in a vertical plane at an angle -4 to +80 degrees, wherein the route guidance after each shot is automatically restored by the servo drive. Rotating turret gun provides guidance in the horizontal plane.

Ammunition gun includes 70 shots, which are in mechanized combat pack in the fighting compartment. Besides, on the right side of the machine there with an armored hatch cover, through which the shots can be made with ground. Ammunition 2S31 Vena did not differ from the shells of 120-mm guns.

The ammunition included with ready rifling on the drive collar of the high-explosive shells PF-49 and PF-51, which operate in the same, as a high-explosive projectiles caliber 152 and 155 mm; rocket-assisted projectile OF50 and cumulative projectile, piercing at a distance 1000 m armor plate thickness above 650 mm. When fired from this weapon can be used by all mortar ammunition 120mm caliber and foreign Soviet. Besides, ammunition "Vienna" refilled and a new guided missile "Kitolov-2M", that guidance to the target is performed by a laser designator.
Auxiliary armament machine represented a 7.62-mm PKT, installed on the roof of the commander's cupola and designed for firing at ground and air targets. Rate of fire 500-600 rounds per minute. Besides, on the frontal armor two block set of twelve 81 mm grenade launchers, used for the production of smoke screens. Release of smoke grenades is done automatically on command laser detector.

2S31 Vena self-propelled guns, "Vienna" is equipped with modern fire control system, which includes a separate periscope sight and sight for direct fire, system of autonomous target acquisition using its own means of surveillance, and reconnaissance, navigation and topographic binding system. Besides, SAU on modern radio communication equipment installed, fire fighting and anti-nuclear defense system, Equipment navigation and topographic location, as well as infra-red night vision devices.

Evaluation of the machine

SAO 2S31 Vena fully compliant, conditions imposed by modern combined arms combat. 2S31 Vena artillery battalions can perform fire missions as part of mechanized infantry or tank units. Use a similar form of organizational structure makes it possible level of autonomy 2S31 Vena on the battlefield, comparable with tanks or infantry fighting vehicles. 2S31 Vena divisions may be given a tank or motorized battalion, having in its composition infantry fighting vehicles BMP-3, as well as to carry out artillery support pobatareyno mouth in the direction of the main attack. According to experts, the combat potential of the tank / infantry guards regiment will double when the division towed mortars replaced by 2S31 Vena Division.

When compared with foreign analogues 2S31 Vena main competition of mortar carrier AMOS, the main advantage of which is the rate. However, this advantage is offset by higher performance combat might ammunition SAO "Vienna", as well as higher precision and accuracy of fire. Besides, With the ability to direct fire support to mechanized infantry and tank units, in lesions of small and area targets, SAO 2S31 Vena completely surpasses AMOS. By combining the basic characteristics and automate, declared SAO 2S31 Vena survival on the battlefield above 3-5 times, and overall efficiency in 2.7-4.5 times higher, than the similar systems of foreign production.
