History
Developed by Athlon Avia (PC-1 Furia operator) and in serial production from 2020, the ST-35 saw a sharp delivery ramp-up after the 2022 Russian invasion.
The ST-35 Silent Thunder was the first nationally designed Ukrainian tactical precision loitering munition in serial production: silent electric propulsion, gliding profile and OFAB-2.5 warhead make it ideal for stealthy engagements against artillery positions and snipers.
