Direct proof of use
Russian use of FAB-250-class bombs in the 2014 Russia-Ukraine War is documented through glide-bomb reporting and munition-remnant analysis. The Guardian reported in April 2024 on a Ukrainian government analysis that described Russia's mass use of high-explosive and cluster bombs fitted with UMPC guidance systems, and said the bombs on which those systems were often attached ranged from the 250 kg FAB-250 to the FAB-1500. The same report tied this weapon class to Russian aircraft attacks on Ukrainian frontline areas, including Avdiivka, Kurakhove, and Kharkiv-region strikes.
A second Russian pathway is the UMPB/D-30SN glide munition. Defense Express reported in March 2024 that photographs from March 8 showed previously unseen Russian ordnance with a UMPB marking and that the weapon was made out of a FAB-250 free-fall bomb. It then reported an official account that Russian forces used three UMPB D-30SN glide bombs against Myrnohrad in Donetsk Oblast on March 10, 2024. Later Defense Express reporting, citing Ukraine's Defense Intelligence component work, described the UMPB D-30SN as a ready-to-use 250 kg aerial guided munition that Russia had used in strikes against Ukrainian cities.
Ukrainian use is documented separately. RBC-Ukraine reported on January 31, 2025, citing Ukraine's Unmanned Systems Forces, that Ukraine was using drones with FAB-250 bombs to strike targets in Russia and that USF command confirmed long-range UAVs capable of carrying a 250 kg aerial bomb and flying up to 2,000 km with the possibility of return. Defense Express and Euromaidan Press described the January 30, 2025 Novozybkov-area case as Ukrainian UAV employment of full-size FAB-250 or FAB-250M-54 bombs against Russian targets in Bryansk Oblast.

Timeline
The Russian glide-bomb record was visible by early 2024. Defense Express reported UMPB-remnant photographs on March 8, 2024 and a March 10 Myrnohrad strike with three UMPB D-30SN glide bombs. In April 2024, The Guardian's account of a Ukrainian government analysis placed Russian UMPC-equipped high-explosive and cluster bombs, including FAB-250-class bodies, in a broader pattern of aircraft-launched standoff attacks on Ukrainian frontline areas.
The Ukrainian FAB-250 UAV record became public in January 2025. Defense Express reported on January 30 that Ukrainian UAVs were carrying and deploying 250 kg munitions in strikes on Russian targets in Bryansk Oblast. RBC-Ukraine reported the following day that Ukraine's Unmanned Systems Forces confirmed the use of long-range UAVs able to carry a 250 kg aerial bomb.

Operational narrative
The FAB-250 appears in this conflict less as a single aircraft bomb dropped in its original free-fall role than as a 250 kg bomb body adapted into several standoff strike forms. For Russia, source-backed claims point to FAB-family bombs fitted with UMPC or UMPK-type guidance modules and to the UMPB/D-30SN, a FAB-250-derived or FAB-250-class guided munition. These adaptations allowed aircraft or other launch methods to strike Ukrainian targets from greater distances than a conventional free-fall attack would require.
For Ukraine, the documented use is a different adaptation: long-range unmanned aircraft carrying a full-size 250 kg aerial bomb. The public record identifies the role as deep strike against Russian rear-area targets, including oil, ammunition, and military-industrial facilities in Russia. The available sources support Ukrainian use of UAVs carrying FAB-250-class bombs, but they do not publicly identify every aircraft model or provide official battle-damage assessment for each strike.
The sources separate possession, adaptation, and use. Russian possession of FAB-family stocks is not the relevant claim here; the conflict-use evidence is the reported employment of UMPC/UMPK-equipped FAB-250-class bombs and UMPB/D-30SN munitions against Ukrainian targets. Ukrainian possession is likewise narrower than the use claim: USF-attributed reporting confirms long-range UAVs capable of carrying a 250 kg aerial bomb, while Defense Express and Euromaidan Press link specific January 2025 strike reporting to FAB-250-class UAV payloads.
