# 2S9 Nona

The 2S9 NONA (Russian: Новейшее Орудие Наземной Артилерии, lit. 'Newest Ordnance of Ground Artillery') is a self-propelled and air-droppable 120 mm 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 over 1,000 2S9 were built.

## Description

The 2S9 Nona-S is an amphibious vehicle that can be propelled through the water by two rear water-jets. It is operated by a four-man crew comprising a commander, a driver/mechanic, a gunner, and a loader. The hull interior is separated into a command compartment, a fighting compartment and an engine compartment. A welded steel turret is located at the middle of the hull. The two-man turret has hatches for the gunner and loader respectively.
The 2S9 utilizes a 120 mm 2A51 mortar with a 1.8 m (5 ft 11 in) barrel. The weapon is actually a hybrid of a mortar and howitzer, being an unconventional design that lacks a direct NATO counterpart. It is a rifled, breech-loaded weapon capable of firing HE (high explosive), white phosphorus and smoke rounds, as well as laser-guided munitions like KM-8 Gran. It can engage in indirect and direct fire, as well as targeting armoured vehicles; its armour-piercing rounds can penetrate the equivalent of 600–650 mm (24–26 in) of steel plate at up to 1 km (0.62 mi).

### Operational history

They have been deployed by Russia during the 2022 Russian invasion of Ukraine. In July 2022, video on social media purportedly shows Ukrainian forces using M777 to destroy a towed 2B16 Nona-K in Hoptivka on the border with Russia. In August 2022, Ukraine's armed forces claimed to use four captured Russian 2S9 against Russian forces. In November 2022, a 2S23-SVK Nona was photographed in Ukrainian service. It was reportedly captured from Russian forces and took months to refit.
On 26 March 2024, Ukrainian forces destroyed a Russia 2S9 Nona 120 mm mortar with a GLSDB and left another “burning” in Zaporizhzhia. In June 2024 Ukraine used a drone to destroy a 2S9 Nona that had been equipped with turtle tank style add on armour.
