Ukrainian naval drone destroys Russian unmanned boat in first drone-vs-drone sea battle

Ukraine's Navy reports its Sargan 3000 unmanned surface vessel, armed with a 12.7mm Protector remote weapons station, destroyed a Russian unmanned boat in the Black Sea. This marks the first recorded engagement between marine drones, a tactical first that signals an evolution in naval warfare. The claim is from Ukrainian sources and unverified independently; the operational impact is limited but the precedent is significant.
