Shadow fleets evade sanctions at sea

Unregistered merchant vessels with transponders off (a 'shadow fleet') enable states to export banned goods and supply forward military positions despite sanctions. These ships cluster regionally, complicate maritime law enforcement, and create attractive, low‑cost targets for drone and standoff strikes that can produce rapid but escalatory effects. — Recognizing and policing shadow fleets changes how policymakers think about sanctions, maritime surveillance, and the use of cheap drones as a tool that both enforces and escalates conflict at sea.
