The FAB-250 UMPK is a Soviet-origin FAB-250 aviation bomb fitted with Russia's UMPK glide-and-correction kit. The conversion gives a 250 kg bomb a pop-out-wing stand-off role, with direct Ukrainian reporting documenting FAB-250 UMPK use in the Russia-Ukraine War 2014-present and separate intelligence reporting tying UMPK-250 assembly to Russia's wartime guided-bomb production chain.
Russian forces use FAB-250 bombs fitted with UMPK glide-and-correction kits in Ukraine; Defence Express documented the conversion in 2023, and Ukrainian prosecutors later identified FAB-250 UMPK bombs in Donetsk Oblast strike reporting.
This entry treats the FAB-250 UMPK as a fitted wartime configuration: the bomb body comes from the FAB-250 family, while the UMPK kit adds wings, navigation, and correction hardware.
| Variant | Configuration | Designation notes |
|---|---|---|
 | Baseline 250 kg free-fall bomb body | Weaponsystems.net describes the FAB M62 family as Soviet free-fall aviation bombs with a common 250 kg version, while this page covers the UMPK-equipped configuration. Sources: FAB M62 | Weaponsystems.net |
The UMPK-equipped weapon is a conversion of the FAB-250 bomb family rather than a clean-sheet munition.
| Compatible item | Item type | Compatibility evidence |

| 250 kg free-fall bomb family | Defence Express identifies the converted munition as a FAB-250 fitted with a UMPK module, while Weaponsystems.net supports the baseline FAB-250 family background. Sources: Defence Express FAB-250 UMPK, FAB M62 | Weaponsystems.net |
Public reporting identifies Russian tactical aircraft, especially Su-34 Fullbacks, as the principal launch platforms for UMPK-equipped FAB-series glide bombs in Ukraine.
| Carrier | Carrier type | Carriage evidence |
|---|---|---|
 | Strike aircraft | JAPCC describes Su-34 Fullbacks as Russia's primary glide-bomb launch platforms in Ukraine and lists FAB-250 among the FAB-series bombs converted with UMPK kits. Sources: JAPCC Glide Bomb Warfare Ukraine |
The page separates the baseline bomb from the kit-equipped configuration because sources use FAB-250, UMPK, and broader FAB-series wording at different levels of precision.
| Layer | Source-backed detail | Catalog treatment |
|---|---|---|
| FAB-250 bomb body | Weaponsystems.net describes the FAB M62 family as Soviet/Russian free-fall aviation bombs with a common 250 kg version. | Used for origin, baseline weight class, dimensions, and the linked bomb-body relationship. |
| UMPK conversion kit | Defence Express reports the FAB-250 conversion, JAPCC describes UMPK as a kit with fold-out wings, navigation, and control modules, and Ukrainian intelligence reporting identifies UMPK-250 assembly in Russia. | Used for guidance, stand-off role, production-chain context, and the fitted-configuration identity. |
| Ukraine conflict evidence | Ukrainian strike reporting and Defence Express identify FAB-250 bombs with UMPK modules in Russian use; JAPCC adds broader FAB-series UMPK employment context. | Supports the Russia-Ukraine War 2014-present usage row while avoiding unsupported claims about every release aircraft or subvariant. |
