Direct proof of use
The 9K33 Osa is directly documented in the 2014 Russia-Ukraine War through Ukrainian operational reporting, allied supply reporting, and visually confirmed Russian and Ukrainian losses. Oryx's Russian equipment-loss list records 40 Russian 9K33 Osa surface-to-air missile systems as visually documented destroyed, damaged, abandoned, or captured during the Russian invasion of Ukraine. Oryx's Ukrainian equipment-loss list separately records 24 Ukrainian 9K33 Osa systems and three Ukrainian 9T217 transloaders for 9K33 Osa as visually documented losses.
Ukrainian use is also supported by reporting on Polish-supplied Osa systems. The War Zone reported in April 2023 that Poland had provided Ukraine with examples of the 9K33 Osa mobile short-range air-defense system. Defence24, citing Ukrainian commander-in-chief Valerii Zaluzhnyi's October 2022 statement about Polish launchers with Soviet missiles, assessed Osa-AKM-P as the most likely system and reported that the Polish-equipped, Poland-trained Ukrainian air-defense unit shot down nine of eleven Shahed-136 drones in its sector.
Later Ukrainian-service reporting shows continued Osa employment and adaptation. Kyiv Post reported that all Ukrainian anti-aircraft missile regiments operating Osa systems received Hornet-project upgrades in 2024, while Army Recognition reported that Ukrainian Osa-AKM systems had been modified to carry R-73 missiles alongside the standard 9M33-series armament.

Timeline
The longform public record for Osa use in this catalog is clearest after the full-scale invasion began on 24 February 2022. Oryx opened separate Russian and Ukrainian visual-loss lists for the invasion and later recorded 9K33 Osa losses for both armies, supporting fielding by both sides in the same conflict phase.
On 11 October 2022, Zaluzhnyi described Ukrainian crews trained in Poland and using Polish equipment to shoot down Russian-launched Shahed-136 drones with Soviet missiles; Defence24's 12 October article identified Osa-AKM-P as the most likely system fitting that description. By April 2023, The War Zone reported Polish 9K33 Osa transfers to Ukraine as part of wider efforts to sustain Soviet-era Ukrainian air defenses.
In 2024, the Ukrainian Osa story shifted from supply and standard 9M33 stocks to adaptation. Kyiv Post reported on 12 December 2024 that Come Back Alive's Hornet project had upgraded all Ukrainian Ground Forces anti-aircraft missile regiments operating the Osa, and Army Recognition reported the same month that the modification allowed Osa-AKM systems to use R-73 air-to-air missiles.

Narrative
The Osa's role in the war is mobile short-range air defense: a self-contained TELAR used to protect forces and sites against aircraft, helicopters, drones, and missiles. The system appears on both sides because Russia and Ukraine inherited Soviet air-defense inventories, and because Ukraine later received additional Soviet-era systems from partners.
For Russia, the strongest public evidence in this record is attrition evidence. Oryx's visually confirmed list places Russian 9K33 Osa systems in the invasion force and records destroyed, damaged, abandoned, and captured examples. Those categories support Russian fielding and battlefield loss of the system, but they do not identify each launch or claimed engagement.
For Ukraine, the record combines pre-existing Osa operation, Polish transfers, drone-defense reporting, and loss evidence. Defence24's October 2022 reporting placed Polish-supplied Soviet-missile launchers in Ukrainian air-defense use against Shahed-136 drones and assessed Osa-AKM-P as the most likely system. The War Zone later stated directly that Poland had provided Ukraine with 9K33 Osa examples, and Oryx's Ukrainian list confirms Osa-family systems and Osa support vehicles in Ukrainian battlefield service through visually recorded losses.
The system remained relevant after the first year of the full-scale invasion because missile stocks for Soviet-era air defenses were finite. Kyiv Post and Army Recognition described the 2024 Hornet upgrade as a Ukrainian effort to keep Osa units operational by integrating R-73 missiles with Osa-AKM systems. That reporting supports continued Ukrainian Osa fielding and adaptation in the war, while the standard Osa missile relationship remains the 9M33 family documented on the parent weapon page.
