Overview

  • Maliuk disclosed that the SBU established a logistics front company in Chelyabinsk with warehouses next to an FSB branch to smuggle 150 FPV drones into Russia
  • He said smuggling methods were modeled on drug-cartel tradecraft and relied on bribed Russian customs officials to clear autonomous truck-mounted cabins
  • Each ‘hunting cabin’ was self-sufficient with EcoFlow batteries and solar panels to keep drones charged in temperatures plunging below minus 40°C
  • The specially built FPV drones carried dual-stage 1.6 kg warheads designed to burn through aircraft skin and detonate internally, damaging 41 strategic bombers on June 1
  • Moscow has since begun constructing hardened bomber shelters and stepped up missile and drone barrages while Western allies face pressure to reinforce Ukraine’s air defenses
