Following an incident in which an unmanned aerial vehicle (UAV) entered Bulgarian airspace near Kardam and exploded on Bulgarian territory, Bulgarian leaders have called for significant upgrades to the nation's defense capabilities.

President Iliana Yotova is coordinating an investigation with the Council of Ministers, security services, and partners in Romania and Ukraine to determine the drone's origin, function, and whether the airspace violation was intentional. Highlighting existing gaps in national defense, the President has called for reforms to bolster anti-drone systems and suggested a meeting among Black Sea nations, excluding Russia, to secure maritime routes.

Political tension has increased following the incident. GERB leader Boyko Borisov criticized the government's response, specifically noting the drone's proximity to the Vertical Gas Corridor, a critical energy transit infrastructure linking Turkey to Europe, Ukraine, and Moldova. Borisov also questioned the professionalism of defense officials, targeting Defense Minister Dimitar Stoyanov's conduct during official duties.

Political figures have continued to urge increased state investment in the domestic military industry. Borisov has emphasized that Bulgaria possesses several factories capable of producing unmanned aerial vehicles and countermeasures, suggesting that the state should provide financial support to strengthen these existing capabilities to address security vulnerabilities.
