Interior Minister Marcin Kierwiński said on September 1 that sabotage was the likely cause, escalating an investigation that prosecutors are conducting as a potential terrorist offense involving a foreign intelligence service. The fire broke out shortly after midnight on August 31 at a warehouse and production building belonging to WB Electronics, part of Poland's WB Group. Firefighters contained the blaze in less than two hours, and no injuries were reported. Prosecutors estimated the damage at no less than **PLN 15 million**, approximately €3.5 million. The affected facility manufactures components for unmanned systems supplied to the Polish Armed Forces. ## Polish prosecutors investigate possible foreign intelligence role The Polish National Prosecutor's Office opened an investigation covering suspected participation in activities by a foreign intelligence service against Poland and the deliberate setting of the fire as a terrorist offense. Investigators believe the fire was deliberately started using a device containing flammable material. Poland's Internal Security Agency, known by its Polish abbreviation ABW, is assisting police and prosecutors. Polish authorities have not publicly identified a foreign state as responsible for the incident. The investigation therefore has not established Russian responsibility, despite broader concerns in Poland and other European countries over suspected Russian sabotage operations targeting infrastructure and companies supporting Ukraine. WB Electronics indicated that the incident should not disrupt deliveries to the Polish Armed Forces. A company representative told Polish media that production could resume after authorities complete their work at the facility. ## WB Electronics supplies FlyEye and Warmate systems WB Group is Poland's largest privately owned defense company and one of Central and Eastern Europe's most significant producers of unmanned military systems. Its portfolio includes the **FlyEye unmanned aerial system**, used for reconnaissance and intelligence missions, and the **Warmate loitering munition**. Both systems have been operated by Ukrainian forces during the war with Russia. The Skarżysko-Kamienna site forms part of this broader Polish unmanned systems industrial base. The facility produces components for platforms supplied to Poland's military, making the investigation directly relevant to the security of Poland's expanding domestic defense supply chain. The incident comes as Warsaw directs a growing share of its defense expenditure toward Polish and Central European manufacturers. Procurement from domestic and Central European suppliers has increased almost fourfold since 2022 to **PLN 30.4 billion**, according to data from Poland's Armaments Agency reported by Reuters on September 1\. That industrial expansion increases the strategic importance of factories producing ammunition, unmanned systems, communications equipment and other equipment required by Poland and its NATO allies. ## Fire adds to security concerns around European defense plants The WB Electronics investigation comes amid heightened concern about sabotage and other hybrid operations against European infrastructure connected with military support for Ukraine. Polish authorities have previously investigated fires and other incidents for potential links to foreign intelligence operations. Prime Minister Donald Tusk said in May 2025 that Russian intelligence services were responsible for a 2024 arson attack that destroyed the Marywilska 44 shopping center in Warsaw. Other European defense facilities have faced suspicious incidents in 2026, increasing attention on physical security across the continent's expanding military production network. The Polish case is particularly significant because investigators are examining the incident not simply as industrial arson but under provisions concerning foreign intelligence activity and terrorism. Germany provided another major development on September 1 when its government attributed an attempted August drone attack at Leipzig/Halle Airport to Russian state actors. Berlin announced diplomatic measures against Russia following the attribution, while Moscow denied responsibility. The two cases are separate, and Polish investigators have not announced evidence connecting the WB Electronics fire to the Leipzig incident. ## Protecting drone production becomes a NATO eastern flank issue The investigation highlights a vulnerability created by Europe's rapid expansion of defense manufacturing. Production capacity for drones, ammunition and other high-demand systems has become part of NATO's broader deterrence infrastructure. Facilities supporting both national militaries and Ukraine therefore carry strategic significance beyond their individual production output. For Poland, the issue is particularly acute. Warsaw is simultaneously expanding its armed forces, increasing domestic weapons production and supporting Ukraine, while its geographic position places major logistics and manufacturing infrastructure close to NATO's eastern frontier. WB Electronics sits directly inside that equation because its unmanned systems serve both Polish and Ukrainian requirements. The immediate question is whether investigators can identify who carried out the August 31 attack and determine whether a foreign intelligence service directed it. Until Polish authorities establish attribution, the case remains an investigation into suspected sabotage rather than a confirmed state-sponsored attack. ## Questions about the WB Electronics factory fire ### What happened at the WB Electronics plant in Poland? A fire broke out shortly after midnight on August 31 at a WB Electronics production facility in Skarżysko-Kamienna. Polish authorities believe the fire was deliberately started, and Interior Minister Marcin Kierwiński said on September 1 that sabotage was the likely cause. ### Is Poland investigating the fire as a terrorist attack? Yes. Prosecutors are investigating suspected foreign intelligence activity against Poland and a terrorist offense involving the deliberate setting of the fire. Poland's Internal Security Agency is participating in the investigation. ### Does WB Electronics produce drones for Ukraine? WB Group produces the FlyEye reconnaissance unmanned aerial system and Warmate loitering munition, both of which are used by Ukrainian forces. The affected facility also produces components for unmanned systems supplied to Poland's military. ### Has Poland blamed Russia for the WB Electronics fire? No. Polish authorities are investigating possible involvement by a foreign intelligence service, but they have not publicly attributed the WB Electronics fire to Russia or another state. Any claim of confirmed Russian responsibility would currently go beyond the evidence publicly disclosed by Polish authorities.
