Direct proof of use
Defense Express reported on February 19, 2026 that Russian occupying forces were using an improvised Kultivator multiple-launch rocket system on a tracked unmanned ground vehicle. The report identified two UB-16-57 rocket launchers mounted on the robotic platform, each carrying sixteen S-5 unguided rockets, and named the Burevestnik Separate Unmanned Systems Regiment as the operator reported by Russian propaganda media.
The same Defense Express report said Ukraine had already demonstrated a similar UB-16-57 installation on ground-based robotic systems and that the 93rd Mechanized Brigade had been using that solution since 2023. A Dailymotion mirror of the Ukrainian item describes the 93rd Separate Mechanized Brigade modifying a ground drone with a UB-16-57 launcher originally designed for aircraft and able to fire up to sixteen unguided S-5 rockets.

Timeline
The Ukrainian side of the public record is dated less precisely than the Russian Kultivator report. Defense Express places the 93rd Mechanized Brigade's use of a UB-16-57 ground-robotic solution in 2023, while the Dailymotion mirror available in 2025 describes the same basic Ukrainian configuration as a 93rd Brigade ground drone with a UB-16-57 launcher.
On February 19, 2026, Defense Express and UNITED24 Media both reported the Russian Kultivator UGV. Their descriptions match on the core configuration: a tracked unmanned ground vehicle carrying two UB-16-57 aviation rocket pods for a total of thirty-two S-5 rockets.

Operational role
In this conflict record, the UB-16UM/UB-16-57 pod appears as an aircraft rocket pod repurposed for short-range ground fire support rather than as a standalone purpose-built launcher. The documented wartime examples place the pod on unmanned ground vehicles, where the launcher gives a small robotic platform a compact salvo of S-5 rockets while allowing the operator to remain away from the launch position.
The role is improvised rocket fire support with important limits. Defense Express reported Russian statements claiming roughly 2 km effective range and about 4 km maximum range for Kultivator, while UNITED24 Media noted that unguided S-5 rockets constrain accuracy and require the platform to work relatively close to contested areas. ARES background on S-5 land warfare shows that repurposing UB-16-57 and UB-32-57 pods for surface-to-surface fire support predates this war, but the Ukraine-specific evidence here is limited to the reported Russian Kultivator and Ukrainian 93rd Brigade ground-drone installations.
