Polish Authorities Investigate Suspected Arson Following Fire at Key Drone Component Plant

Fire began around 12:23 a.m. on August 31 at the WB Electronics plant in Skarżysko-Kamienna, with an intrusion alarm triggering police contact.
Surveillance footage shows a masked intruder entering the site by crossing the perimeter fence, and a backpack and sweatshirt were found near the facility.
Poland’s security apparatus has mobilized in the investigation, with five firefighting crews at the scene and authorities seriously considering arson; internal security agencies including ABW and the Military Counterintelligence Service involved.
WB Electronics’ Skarżysko-Kamienna facility produces pump systems for unmanned aircraft and unmanned ground platforms, including equipment used in drones such as FlyEye and Warmate that Poland and Ukraine rely on.
The plant is located in Skarżysko-Kamienna, about 150 kilometers south of Warsaw, underscoring its strategic role in Poland’s defense sector.
A fire broke out at WB Electronics' drone plant in Skarżysko-Kamienna, Poland, early on August 31, prompting a major arson investigation. Defence Blog reported that surveillance footage captured a masked intruder crossing the perimeter fence before the blaze started around 12:23 a.m. Authorities found a backpack and sweatshirt near the facility, and no injuries were reported since the plant was not operating at the time.
The facility produces pump systems for unmanned aircraft and drones like FlyEye and Warmate used by Polish and Ukrainian forces. Yahoo News reported that Poland's domestic intelligence service ABW is investigating possible sabotage, treating the incident as a serious threat to critical defense infrastructure amid a broader pattern of fires at European weapons makers in 2026.
Emergency responders mobilized quickly after an intrusion alarm alerted police to the break-in. Defence Blog reported that five firefighting crews rushed to the Skarżysko-Kamienna plant, located about 150 kilometers south of Warsaw. Firefighters contained the fire after it began in the early morning hours, preventing further damage to the strategic defense facility.
Security cameras recorded a masked person crossing the perimeter fence shortly before the fire started. United24media reported that investigators recovered a backpack and sweatshirt abandoned near the site. The recovered items provide crucial evidence as authorities work to identify the intruder and determine whether the break-in directly caused the fire.
The domestic intelligence service ABW mobilized immediately, signaling that authorities view the incident as potential sabotage. Yahoo News reported that Poland's Military Counterintelligence Service also joined the investigation. Arson ranks among the leading theories as investigators examine whether hostile actors deliberately targeted the weapons supplier.
The WB Electronics fire adds to mounting attacks on European defense makers in 2026. Defence Blog noted that fires, explosions, and suspected sabotage have hit multiple weapons manufacturers across the continent. The incidents highlight growing security risks to defense supply chains, especially as Poland and Ukraine depend on WB Electronics' unmanned systems for military operations.
