As European countries invest billions into bolstering Ukraine’s drone capabilities, Ukrainian forces are using those drones to inflict significant damage deep behind Russian lines.

In this footage, Ukrainian UJ-26 Beaver drones can be seen targeting and striking Russian radar systems, air defenses, and even a Su-30 strike fighter in Crimea.

One clip shows a Russian Pantsir surface-to-air missile system repeatedly failing to intercept an incoming Ukrainian drone—moments before being struck itself.
