2S9 Nona

The 2S9 NONA (Новейшее Орудие Наземной Артилерии - Newest Ordnance of Ground Artillery) is an extremely light-weight self-propelled and air-droppable 120 mm gun-mortar designed in the Soviet Union, which entered service in 1981. The 2S9 chassis is designated the S-120 and based on the aluminium hull of the BTR-D airborne multi-purpose tracked armoured personnel carrier. More generally, the 120 mm mortar is referred to as the Nona, with the 2S9 also known as the Nona-S. Although no figures have been released, it is estimated that well over 1,000 2S9 were built.
