SAU 2S34 "Host" is intended for the destruction of the control points, firepower, armored targets, missile, mortar and artillery batteries, as well as enemy troops at distances up 14 000 m.

ACS sufficiently simple in design, has reliable and rugged with increased resistance to undermine the anti-tank mines, new weapons, It equipped with automated guidance and fire control system in the conditions of modern warfare. All these qualities allow the 'host' to perform virtually all tasks, for which are self-propelled guns.
The troops ACS "Host" enters under the symbol 2S34. As part of the comprehensive modernization of the prototype, SAU 2C1 "Carnation", on the "Host" performed work, not only for the howitzer 2A31 replaced by semi-automatic weapon, which combines the functionality of mortar, gaubitsы and guns, but many other innovations. The most important of these automatic recovery after the shot aiming guns (due to the installation of servo drives), appearance on the cradle artillery unit SAU gyroscope, coupled with the CEC.
In 2S34 self-propelled guns were taken and other constructive solutions, used in perspective sighting and navigation system 1V180-2, which in its entirety will be installed on the new ACS 2S35 (work on it are under way). All these improvements make it possible to speak of a substantial increase in combat effectiveness of the new ACS in 2S34 modification (almost three times).
2A34 "hosta" can fire ammunition caliber 120 mm, the effectiveness of which is comparable with a high-explosive projectiles caliber 155/152 mm, all available today caliber mines 120 mm (USSR production, Russia and NATO countries), precision-guided projectiles newest type "Kitolov-2", equipped with a passive homing. GOS design allows you to receive a laser designator, reflected the purpose of.
For the first time on the ACS of this class an automated GC, which performs guidance tools in two planes according to shooting, previously calculated by the system itself. topogeodesic binding system dubbed SAU (satellite and autonomous orientation). Significantly increased precision and accuracy of fire due to installation of a new clock system optoelectronic reconnaissance and target designation.
Conducted as part of the modernization improvements allow us to say, that ACS 2S34 "Hosta" long enough to be on their combat characteristics are among the most efficient in its class fire systems. Her sighting rate increased from 4 to 9 rds. / min. Almost combat capabilities of ammunition used has doubled. Minimum range bezrikoshetnoy firing high-explosive shells was reduced from 4 to 1,5 km, mines - to 0,4 km. The maximum firing range remains unchanged.
Constructive decisions (Installation on the barrel overheating indicator, cooling system, reduction gassed combat compartment and t. P.), applied during manufacture 2S34, positive impact on the modes of fire and reducing the time, necessary for calculating the first shot. Calculation of "hosts" got two-way telecode due to higher levels of government.
SAU 2S34 "Host" is mounted on the base unit improved its prototype 2S1, ML-TB, on which the tower of circular rotation of new design. In the tower there is a new universal semi-automatic weapon, equipped with a muzzle brake. On modernized "Host" used many technical improvements, used before on ACS "Vienna" (Chassis - BMP-3), "Nona-SWR" and "obaekta 118» (tracked minnogo zagraditelâ).
New ACS can fire straight or half-open with fire, semi-closed and closed positions. At the same time they do not need pre-treatment. An important advantage of the new ACS is inherent in it to hit targets on the reverse slopes of heights, which makes it indispensable in the conduct of military operations in the mountains.
Full-scale modernization of on-board equipment to the level of the new ACS 2S34 is planned in the first phase only command vehicle (battery commander and above). On the other ACS established the JMA in a few truncated form (analogue of automated guidance and fire control system "Success-C").
Alternatively discusses how to use the ACS 2S34 "Host" in conjunction with the automated control of machines by artillery fire of the "Skit-B" and complex "Zoo-1", carrying out artillery reconnaissance. Combat capabilities of machine installation, the last partial modernization, no data units are slightly reduced. But still they will be much higher 2S1.
A significant depreciation of the modernization and the ultimate cost of the "Hosts" makes this option (partial modernization systems SAU) justified with at least two points of view. At first, as of 2011 g. in service with the Russian Armed Forces were CB 2965 SAU 2S1, which are necessary to upgrade. Secondly, relatively inexpensive SAU, having the possibility of firing all the ammunition of NATO and has a fairly high combat capabilities, It will be sought-after commodity on the arms market in third countries.
