2S31“Vena”
120 mm self-propelled artillery gun on BMP-3 chassisRole
A tracked self-propelled artillery system for direct fire support of motorised rifle units, built on the BMP-3 chassis. It is the final link in the Soviet/Russian “Nona” family (2S9 “Nona-S” on the BTR-D → 2S23 “Nona-SVK” on the wheeled BTR-80 → 2S31 “Vena” on the tracked BMP-3), preserving the common philosophy of a universal 120 mm rifled gun-mortar. Vena differs from its predecessors with a longer 2A80 barrel of 30 calibres (versus 24 in the 2A60), pushing HE range to 13 km, and the integrated “Kapustnik-B” fire-control suite: digital ballistic computer, commander’s thermal sight, satellite navigation, support for the “Kitolov-2” guided round. The vehicle is amphibious — it crosses water obstacles with two waterjets inherited from the BMP-3. Adopted in 2010; built in a small series of about 40 units.
