The 3OF44 is a Soviet 203 mm rocket-assisted high-explosive fragmentation projectile for 2S7-family heavy artillery. Sources identify it as the projectile in the separate-loading 3VOF35 Burevestnik-2 round, distinguish its longer 47.5 km range from the standard 3OF43 projectile, and tie the round to the 2S7 Pion and 2S7M Malka rather than to independently documented conflict use.
The 3OF44 is the rocket-assisted member of the same 203 mm 2A44 ammunition family represented by the standard 3OF43 high-explosive projectile.
| Variant | Configuration | Designation notes |
|---|---|---|
 | Standard 203 mm HE-FRAG projectile | ARES and Russian ammunition references list 3OF43 with a heavier explosive fill and shorter maximum range than the rocket-assisted 3OF44. Sources: Ukrainian government returns 2S7 Pion self-propelled artillery to service, 203 mm 3OF43 projectile in 3VOF34 and 3VOF42 rounds |
3OF44 is the rocket-assisted 203 mm HE-FRAG projectile in the 3VOF35 round for the 2S7 family.
| Firing weapon | Weapon type | Firing evidence |
|---|---|---|
 | 203 mm self-propelled gun | Sources describe 3OF44 as the HE-FRAG projectile in the 3VOF35 round for the 2S7 family and document it as a 203 mm projectile available for the 2S7 Pion system. Sources: 203mm shells for 2A44 howitzer, Ukrainian government returns 2S7 Pion self-propelled artillery to service, 203 mm 3VOF35 round with 3OF44 projectile, 3OF44 | METIS |
 | Modernized 203 mm self-propelled gun | The specialist ammunition reference states that the 3VOF35 round with the 3OF44 projectile is used for firing from both the 2S7 Pion and the modernized 2S7M Malka. |
ARES places 3OF44 beside the standard 3OF43 high-explosive projectile for the same 203 mm system. The difference is easy to read: 3OF44 buys more range with a smaller explosive fill.
| Projectile | Explosive fill | Maximum range | Notes |
|---|---|---|---|
| 17.8 kg | 37.4 km | Standard HE projectile cited by ARES. |
| 3OF44 rocket-assisted HE-FRAG projectile | 13.32 kg | 47.5 km | Rocket-assisted projectile cited by ARES, Fenix Insight, and the specialist ammunition reference. |
The complete 3VOF35 round is separate-loading ammunition built around the 3OF44 projectile and a full propelling charge. The source-backed component list is useful because the projectile designation and complete-round designation are often mixed in shorthand references.
