Context: before NATO’s decision, Bulgaria requested counter-drone reinforcements and announced its participation in an allied initiative
Before NATO announced additional measures in the Black Sea, Bulgaria asked the Alliance to deploy fighter jets, missile defense systems, and counter-drone equipment on its territory in response to attacks on commercial vessels reported since October 5. According to Defense Minister Dimitar Stoianov, Bulgaria already had two threat detection and surveillance systems and was preparing to install a third.
Also before NATO stepped up its response, Stoianov said that Sofia expected to join, by October 30, an Alliance initiative for defense against drones, following incidents off the Bulgarian coast, including the sinking of a vessel.
