The 3OF50 active-rocket projectile is a Soviet-origin 120 mm rocket-assisted high-explosive fragmentation projectile for Nona-family gun-mortars. It forms the projectile component of 3VOF55 and 3VOF55-1 semi-fixed rounds, pairing an A-IX-2 filled warhead with a rocket motor and pre-engraved driving band to extend Nona fire support beyond standard 120 mm ammunition.

Nona Ammunition Context

Public references identify 3OF50 chiefly through ammunition and firing-platform contexts. The useful distinction is that 3OF50 is the rocket-assisted HE-fragmentation projectile in the 3VOF55 / 3VOF55-1 round family, while the firing platforms are the 120 mm Nona gun-mortars.

METIS distinguishes the projectile from complete rounds: 3VOF54 combines 3OF49 with the 3V35 impact fuze, while 3VOF54-1 uses the AR-5 radio/proximity fuze. Belspetsvneshtechnika lists both fuze configurations for the 2S9 Nona-S, and VPK attributes Nona ammunition development to Basalt.
