Description
Introduction
The 2S9 Nona-S is a self-propelled mortar of Soviet origin. It was developed in the 1970's to improve the mobility of mortars serving with the air assault divisions. Additionally it provides a direct fire and and a limited anti-tank capability. The 2S9 is one of the the most numerous gun-mortar systems in the world.
Layout
The chassis of the BTR-D armored personnel carrier serves as the basis for the 2S9. In the middle of the vehicle a large turret is placed that is fitted with a breech loaded gun-mortar. The commander and driver are seated in the hull and the gunner and loader in the turret.
Firepower
The 2A51 breech loaded 120mm smoothbore gun-mortar is the main armament of the 2S9. The turret allows for a limited traverse left and right. The maximum effective range is 8.8 km and 13 km with assisted ammunition. The rate of fire is 6 to 8 rounds per minute. As a gun mortar it is capable of direct fire and special HEAT ammunition is available for use against armored vehicles. There is no secondary armament.
Protection
The 2S9 is operated under full armor protection. The aluminium armor protects against shell splinters and small arms fire.
Mobility
The tracked chassis with hydropneumatic suspension provides a good cross country mobility. A 240 hp diesel engine provides propulsion. The 2S9 can be paradropped from a variety of aircraft.
Users
The 2S9 Anona is widely used in Russia and former states of the CIS. Unlike most Russian military equipment it is hardly used in Eastern Europe and saw limited exports.
