The 2S17-2 Nona-SV is a Ukrainian realization of a Soviet Nona-family concept: a 120 mm 2S9 Nona turret and gun-mortar fitted to a BRM-1K, BMP-1, or PRP-family tracked chassis. Open sources describe it as a way to recover Nona firepower when original BTR-D-based 2S9 hulls were scarce, and direct battlefield reporting ties the conversion to Ukrainian service and losses during the 2014 Russia-Ukraine War.
Ukrainian forces fielded the BRM-1K/BMP-family Nona conversion during the full-scale war; Defense Express reported multiple vehicles together in 2023, while Oryx lists visually confirmed Ukrainian losses under the exact BRM-1K with 2S9 Nona turret description.
Role detailsThe public evidence points to a practical wartime conversion rather than a clean factory-new artillery vehicle. Sources agree on the core idea: a Nona turret and 120 mm weapon package were installed on a more available BMP-family tracked hull after the original BTR-D-based 2S9 fleet became difficult to sustain.
Defense Express cautions that BMP-1, BMP-2, and BRM-1K hulls can be difficult to separate from side imagery after conversion work, especially when ports or fittings are covered.
The exact conflict-use row relies on sources that identify the 2S17-2 or BRM-1K-with-2S9-turret vehicle in Ukrainian service, not just general 2S9 Nona use.
The best open count found in this pass is a small batch: four to five vehicles seen together by March 2023. A full production total is not publicly confirmed.

Nona-SV sits inside the wider Soviet/Russian Nona 120 mm gun-mortar family, but the 2S17-2 designation is used here for the tracked Ukrainian conversion on a BRM-1K/BMP-family chassis rather than the original BTR-D-based 2S9.
| Variant | Configuration | Designation notes |
|---|---|---|
 | Original tracked airborne Nona system | Defense Express describes the Ukrainian conversion as a new version of the 2S9 Nona self-propelled 120 mm mortar with the BTR-D landing-vehicle chassis replaced by a BMP-1 or BRM-1K-type chassis. |
 | Wheeled BTR-80-based Nona family member | Tank Encyclopedia places the 2S17 and 2S17-2 Nona-SV projects in the same Nona-family effort as the later wheeled 2S23 Nona-SVK branch. |
 | Towed Nona-family 120 mm gun-mortar | The towed 2B16 is a separate Nona-family branch; it is linked for family context, not as a chassis or turret donor for the 2S17-2 conversion. Sources: Defense Express Nona-SV production report, Tank Encyclopedia 2S23 Nona-SVK history |
The 2S17-2 is best understood as a conversion that joins an available Soviet tracked reconnaissance or infantry-fighting-vehicle hull with the Nona turret and 120 mm weapon package.
| Compatible item | Item type | Compatibility evidence |
|---|---|---|
 | Tracked reconnaissance chassis | Popular Mechanics identifies the Ukrainian 2S17-2 as a conversion mounting a 2S9 turret on a BRM-1K reconnaissance-vehicle hull, while Defense Express says the exact BMP-1/BRM-1K chassis identification can be difficult from available imagery.

 | BMP-family tracked chassis context | Defense Express describes the conversion as replacing the original BTR-D chassis with a BMP-1 or BRM-1K-type chassis, and notes that side-view details can make the exact base vehicle debatable. |
| Nona turret and 120 mm gun-mortar source | Oryx lists the visually confirmed Ukrainian losses as BRM-1K vehicles with 2S9 Nona turrets, and Popular Mechanics describes the same turret-on-BRM-1K conversion. Sources: Oryx Ukrainian equipment losses, Popular Mechanics Nona and Vena context |
Tank Encyclopedia places the 2S17 and 2S17-2 Nona-SV concepts in late-1970s to early-1980s Soviet work to give ground forces a Nona-style self-propelled mortar.

Defence24 reports that the BRM-1K-based 2S17-2 work was abandoned in 1982 in favor of other Soviet mortar projects.

Popular Mechanics reports that Ukraine's Shepetivka Repair Plant realized the BRM-1K Nona-SV concept in 2021; Defence24 separately notes open claims that Ukrainian vehicles may have been produced by 2021.

Defense Express assessed that footage showing four to five vehicles together meant the 2S17-2 Nona-SV had moved beyond a single one-off conversion.
