In a historic clash, a Ukrainian naval drone felled a Russian explosive drone boat in the Black Sea, marking the world’s first drone-on-drone battle. Defence Intelligence detected a Russian Orcan drone, a jet ski-like vessel designed to ram and explode, and directed a Ukrainian Navy drone boat to intercept. The Sargan-3000, armed with a 12.7mm machine gun, disabled the Russian drone's communication antenna and then sank it from one kilometer away, as shown in a video from the Ukrainian government platform United24.

This encounter underscores the escalating role of autonomous vessels in modern conflicts. Naval analyst HI Sutton noted that similar uncrewed surface vessels (USVs) and flying drones often work in tandem, with Russian Geran drones providing aerial reconnaissance and boosting communication between operators and drone boats.

The use of such USVs by both sides has been increasing, with these vessels already deployed to attack Ukrainian ports and ships. Sutton observed, 'It was inevitable that USV-on-USV combat would occur, just as we have seen in the air and on the ground.' This event, while tragic, signals a new era of automated conflict.

The battle on September 12 highlights the rapid evolution of maritime warfare technology. As autonomous systems become more sophisticated, the nature of naval engagements is likely to change, making such drone-on-drone confrontations a more common sight in the years to come.
