Ukraine's maritime drone campaign moved out of the Sea of Azov and into the Black Sea overnight on 15 July, under the name Operation "MoLoChKa", striking 20 vessels in one night: 17 oil tankers, two gas tankers and a tugboat 1. Two of the named targets, the Louise 1 and the Banda, were running dark on AIS, the automatic identification system merchant ships are required to broadcast, while carrying Russian crude in breach of the price cap set by the G7 group of industrial democracies and the EU. An SBU Sea Baby uncrewed boat had hit the tanker Blue near Yalta a week earlier, on 8 July. The Unmanned Systems Forces struck twelve more vessels on 17 July, taking the 6 to 17 July total to 159 shadow-fleet vessels across both seas 2.
Eleven days before the expansion, the same campaign was a chokepoint tactic confined to the Azov, where it cut tracked traffic by 55% . The Azov is shallow, narrow and effectively closed; the Black Sea is neither, and holding vessels at risk across it demands range and endurance the Azov operations never had to demonstrate.
The G7 and EU price cap runs on insurance certificates and port-entry checks, and a tanker that switches off its transponder, reflags through a shell registry and transfers cargo ship-to-ship outside territorial waters encounters none of them. Sea drones do not need to establish ownership before they arrive. The harder a vessel works at being untraceable, the fewer parties can be identified to protect it, and opaque ownership stops being cover and starts being exposure.
