Armament Research Services reported on July 3, 2014 that imagery and video from near Kramatorsk showed remnants consistent with 300 mm 9M55K cargo rockets and unexploded 9N235 fragmentation submunitions. ARES identified the distinctive Smerch rocket components and wrote that the presence of 9N235 submunitions differentiated the 9M55K cargo rocket from other Smerch cargo rounds.
The OSCE Special Monitoring Mission later documented a January 27, 2015 strike in Luhansk city. Its spot report described rocket engines, fins, and cargo compartments in residential yards and identified the parts as consistent with 300 mm 9M55K Smerch rockets.

Timeline
The documented Ukraine-war record begins in July 2014 with the Kramatorsk-area ARES report. Human Rights Watch's June 2015 technical briefing then summarized field investigations in eastern Ukraine, stating that both Ukrainian government forces and Russian-backed separatists had used cluster munitions since mid-2014 and listing 9M55K Smerch rockets among the ground-fired cluster munitions documented in Donetsk and Luhansk provinces.
After Russia's full-scale invasion began on February 24, 2022, 9M55K-series Smerch rockets remained part of the documented cluster-munition pattern. Human Rights Watch identified 9M55K Smerch cluster munition rockets in Kharkiv on February 28, 2022, while Bellingcat described 9M55K and 9M27K cluster rockets as common documented cluster munitions in early 2022 Ukraine.

Operational pattern
In this conflict, the 9M55K was documented as a Smerch-family area-fire munition rather than a precision strike weapon. It was fired from 9K58 or BM-30 Smerch launchers and dispersed 72 9N235 fragmentation submunitions from a 300 mm cargo rocket, giving it a different evidence trail from unitary high-explosive Smerch rounds.
Attribution varies by incident and period. ARES assessed the July 2014 Kramatorsk evidence as most likely Ukrainian fire, while Human Rights Watch and the Cluster Munition Monitor summarized 2014-2015 use by both Ukrainian government forces and Russian-backed anti-government forces. In 2022 reporting, Human Rights Watch attributed documented Kharkiv 9M55K Smerch attacks to Russian forces, and later summaries described extensive Russian cluster-munition use alongside evidence or reports of Ukrainian use in other incidents.
