Direct Proof Of Use
The clearest public evidence for 100 kg / 220 lb bomb-class use in the 2014 Russia-Ukraine War comes from Ukrainian light-aircraft UAV adaptations. In April 2024, The War Zone reported photos of a crashed Skyranger light aircraft that had been modified for remote operation and carried an OFAB-100-120 aerial bomb under the fuselage. The article identified shackles indicating the bomb was intended to be dropped and noted that the crash location and date were not specified in the original Russian Telegram source.
Open Source Munitions Portal records separately list OFAB-100-120 images in its Ukraine and Russia 2022-2026 collection as air-delivered bombs reported in Ukraine. The OSMP entries do not by themselves identify the operator, but they corroborate the munition identification and conflict-theater context for the same 100 kg fragmentation-bomb model.
Timeline
Public reporting traces the bomb class from an April 2024 wreckage appearance to later accounts of Ukraine's reusable bomber-drone adaptations. Defense Express reported in January 2025 that earlier versions of these UAVs had used FAB-100 bombs before evidence emerged of heavier FAB-250 carriage. In October 2025, Babel published a field report on the Ukrainian Gorynych deep-strike group, describing OFAB-100-120 bombs from Ukrainian stocks and showing the same munition class among the group's payloads.

Ukrainian UAV Adaptation
In this conflict-use record, the FAB-100 / 220 lb bomb is best understood as a legacy Soviet aerial bomb repurposed for unmanned strike aircraft rather than as a conventional fast-jet munition. The War Zone's 2024 report tied the OFAB-100-120 to a converted Skyranger airframe, and Defense Express later described the broader Ukrainian practice of carrying full-size aerial bombs on UAVs, with FAB-100 loads preceding heavier FAB-250 payloads.
Babel's October 2025 report connected the Gorynych aircraft to a Ukrainian deep-strike group in the 14th Regiment of the Unmanned Systems Forces and described OFAB-100-120 bombs as available from Ukrainian stocks. The same report and the official 1st Separate UAS Center history place the 14th UAS Regiment in Ukrainian unmanned combat operations during the full-scale phase of the war. The public record does not give a complete sortie-by-sortie list for FAB-100-class use, but it does directly support Ukrainian employment of the 100 kg bomb class on converted long-range UAVs.
