Development and design

Its turret carries the 2A80 rifled gun-mortar and advanced fire-control equipment, while the BMP-3-derived hull provides amphibious mobility and commonality with mechanized units. 1, 2

Operational use

The vehicle was developed as a higher-capability successor or complement to earlier Nona-family systems, though it has been fielded on a much smaller scale than 2S1 or 2S19. 1, 2

Role and significance

Vena is especially useful in the archive as a cross-type example: BMP-3 automotive lineage supports an artillery mission, demonstrating why chassis family and battlefield classification must remain separate. 1, 2
