On September 24, 2026, Flightradar24 tracking data appeared to show a Safran Patroller surveillance drone flying near Poland’s border with Belarus.
The data, shared on social media, showed an aircraft identified as a Safran S-15 Patroller flying north along the border near the Białowieża Forest. No registration or operator was displayed.
The listing prompted reports that an unidentified French surveillance drone was operating on NATO’s eastern flank, an area that has received increased attention following a series of drone incidents, including the entry of Russian drones into Polish airspace on September 9 and 10, 2025.
🇵🇱 A very close look at the Polish-Belarusian border today.

A Safran S-15 Patroller surveillance UAV is currently flying a low-speed ISR mission directly along Poland's eastern border with Belarus, passing the Białowieża/Hajnówka area.

Same airframe, same flight-tracking code
The aircraft was, however, most likely a crewed Polish Border Guard surveillance aircraft rather than a French-built drone. The likely explanation lies in the Patroller’s origins. Safran developed the Patroller from the Stemme S15 motor glider.
The Polish Border Guard operates two crewed Stemme ASP S15-1 aircraft, registered SP-VSO and SP-VSP. The service lists the ASP S15-1 in its aviation fleet and uses it for missions including surveillance of Poland’s land and maritime borders and observation of low-flying aircraft and other objects near the frontier.
According to the Border Guard, the two Stemme aircraft have been used for border surveillance since September 2015 and are equipped with optoelectronic systems allowing long-range observation.
With Flightradar24 using the same S15U aircraft type code for both platforms, the same confusion has occurred before.
On September 23, 2025, an aircraft identified by flight-tracking services as an S15U appeared near the Belarusian border. Polish military aviation tracking account PolishMilRadar subsequently identified it as a Polish Border Guard aircraft rather than a surveillance drone.
Aircraft of the type have continued to fly similar surveillance routes near Poland’s eastern border.
France received Patrollers but never made them operational
The appearance of the aircraft on flight-tracking services also revived claims that the Patroller had entered service with the French Army.
France did receive Patroller aircraft, but the system never reached operational service before the program was abandoned.
The French defense procurement agency (DGA) ordered the Patroller from Safran in April 2016 to replace the Sperwer tactical drone. The original contract covered two operational systems comprising five air vehicles each, together with a four-aircraft training system.
After years of delays, a first production air vehicle and ground station were delivered to the French Army in May 2024. Patrollers were subsequently used for training and technical-operational evaluation at the 61st Artillery Regiment, but the system was never declared operational.
The 2024-2030 military programming law had meanwhile substantially increased France’s ambitions for the platform. It set a target of five tactical drone systems and 28 air vehicles by 2030, with the Patroller also due to receive an armed capability.
Patroller program abandoned after years of delays
The program had already suffered a major setback when a Patroller crashed during a test flight in December 2019. Delivery and certification difficulties subsequently pushed the program years behind schedule. By 2026, France had changed course.
On April 8, 2026, Armed Forces Minister Catherine Vautrin told the National Assembly defense committee that the government had chosen to abandon several programs, including the Patroller tactical drone.
The decision was incorporated into the update of France’s 2024-2030 military programming law, adopted in August 2026.
Army Chief of Staff General Pierre Schill later described the Patroller program as a failure, telling senators in May 2026 that the Army had initially specified requirements that were too ambitious and that certification for autonomous flight had proved particularly difficult.
France is instead pursuing the ADAPT program to procure a replacement for the Safran Patroller, alongside lighter tactical drone systems.
