ST35 Silent Thunder (a03ead4e-31fe-5296-9c5f-7b260b375110)
The ST‑35 “Silent Thunder” is a Ukrainian‑produced electric loitering‑munition UAV built by Athlon Avia. Weighing 9.5 kg with a 3.5 kg multi‑purpose warhead (FAE, HEAT or HEF), it can hover for up to one hour, travel 30 km and operate at 800‑1 200 m altitude at 120‑140 km/h cruise speed. Launch is vertical via a detachable multirotor that also relays command‑and‑control data, allowing a three‑person team to carry the system in backpacks. Once a target is identified—automatically or by the operator through TV/IR feeds—the munition detaches, dives vertically and strikes with a 95 % hit probability, minimizing collateral damage in dense urban environments. Currently fielded by Ukraine.
