SAU 2S9 "Nona-C" – a self-propelled artillery gun caliber 120mm

Self-propelled gun 2S9 "Nona-S" is considered to be unique, artillery system, which was created specifically for direct fire support of airborne troops on the battlefield. The need for such a machine there, when there were plans to use the "winged infantry" on enemy territory. At the same time huge role airborne self-propelled artillery. However, the existing models of AMS-57 and ASU-85 were designed to fight tanks. Besides, They were not quite suitable for landing, because it required transport airplane landing on runway, which eliminated the suddenness. That is why in the mid 60s. work started, aimed at creating a more user-friendly and yet powerful machine.

In the mid-70s. on a competitive basis in the Volgograd and Kurgan machine-building plants designers built two light tanks - "Object 934" and "Object 685". The primary weapon is used in these machines of long 100 mm cannon. But the machines were not accepted for service because of their lack of power. At the same time designers Central Research Institute of precision engineering in cooperation with Perm engineers known "Motovilikha" created a new and unique 120-mm rifled gun 2A51, able to effectively support ground forces. This artillery system successfully combines gun, gaubitsu and mortar. The machine has been assigned an index 2S9 "Nona-S", and, according to legend, This name can be deciphered as "new gun ground artillery". This self-propelled gun in combat conditions is capable of performing multiple functions: destroy enemy fortifications, hitting manpower opposite side, and destroy enemy tanks. FROM 1981 g. the car became mass-produced. There were created more 1000 copies. Until today, this machine is on service in Russian army and in many armies of the CIS countries.
From the start, designers planned to create a mobile artillery system, so the machine has a relatively low weight and was originally designed to transport aircraft and helicopters. Furthermore, it can mnogokupolnyh parachute via parachute and parachute systems reactive system PRSM-925.

"Nona-S" was created based on a tracked armored personnel carriers BTR-D, which is characterized by an elongated one roller chassis and the lack of a turning tower. The housing of the new self-propelled gun in this connection has been welded aluminum armor alloy thickness 15 mm. The bow of the hull contained control branch, housed the commander and driver. Fighting compartment in the middle part of the machine. Power pack with engine 5D20-240, transmission, water cannons, fuel tanks were located in the stern self-propelled. A powerful motor enables the machine to reach a speed of 60 km / h on the highway, and 9 km / h afloat.
The tower was equipped with a weapon 2A51, sight 1P8, vision devices (TNPO two-170A, MK-4), and Electrical- and pneumatic equipment. Ride achieved via controlled suspension, which is also allowed to change the amount of clearance, for example by reducing it to 35 cm.
of guns, mounted on a self-propelled, you can shoot all types of mines, 120 mm caliber, which are in production in the Russian industry, and already stored in warehouses. Besides, taking into account the specifics of the landing assault for shooting must have been approached and the potential enemy ammunition. That is why the original instrument has been calculated and the application of French 120mm min, but later tests showed, that it can be successfully shoot ammunition Israel, Chinese, German and Spanish production.

If desired caliber mines already existed at the time the 2S9 "Nona-S", the shells had to develop anew. In the process of hard work in this direction were ZVOF54 shots with high-explosive fragmentation projectile ZOF49, ZVOF49 with high-explosive fragmentation projectile ZOF51, ZVOF55 with active-reactive high-explosive shells and cumulative ZOF50 ZVBK14 shot with rocket-assisted projectile ZBK19. When shooting using the unique structural and ballistic scheme of "gun-shot", this does not apply to other instruments. 2A51 is threaded, breech-loading, having an unusual design, utilizing caseless ammunition loading.
Rupture explosive A-IX-2 in the implementation generates a shot 3500 fragments weighing from 0,5 to 15 g. The thickness of the armor punctured at a distance equal to 15-20 m 8 mm, at a distance of 7-10 m - 12-14 mm. Shooting from the self-propelled gun is only possible from space, both indirect fire, and direct fire. Horizontal guidance is performed at an angle 70 degrees (by 35 degrees to the side), vertical range from -4 to + 80 °. Rate can be as high 10 rounds per minute. Ammunition CAO is 25 shots: five cumulative projectiles, 20 mines or other ordnance in any combination. Besides, it includes 13 case with two full charges on the charger each and 20 packets of powder beams to complete variable charges, arranged in two boxes. With prolonged use of tools in the battle ammunition feeding is performed from the ground by a special tray.

The gun has a combined semi-automatic shutter with plastic obturator of propellant gases, who is also shot in the barrel rammer. Dosylka by means of compressed air.
ACS has three observation devices TNPO-170A, located in front of the hatch mechanics, whereby the central if appropriate easily replaced bespodsvetochnym night vision device TVNE-4B or TNP-350B. Luke commander are also two instruments TNPO-170A and tank periscope TPK-2.
During his combat use, in particular in Afghanistan, “Nona-C” He has shown such good results, that itself was born the decision to supply the likes of self-propelled guns, not only VDV, but the Marines, and the Army. To this end, an instrument was created 2S9-1 "Sviristelka". TO 1986 g. Russian designers have developed a towed 2B16 "Nona-K"
