**Deck**: NASA satellite fire data shows multiple large blazes at the Tsumbulova Test Site in Russia’s Oryol Oblast after reported Ukrainian drone strikes on the country’s largest Geran launch complex.

Multiple large fires broke out at the Tsumbulova Test Site in Russia’s Oryol Oblast after reported Ukrainian drone strikes, according to satellite fire-detection data. The site is described as Russia’s largest launch area for Geran-series drones, making any damage there a potentially significant development in the drone war.

NASA’s FIRMS platform, which tracks heat signatures from space, indicated several substantial fire detections over the Tsumbulova area following the reported attack. These thermal anomalies line up with the location of the established test and launch site.

The Tsumbulova Test Site is used to launch Geran-2 drones, along with Geran-4 and Geran-5 jet-powered drones. It has undergone rapid expansion for the last two years. Open-source reporting characterizes it as the largest drone launching site in Russia and notes that it has recently been repeatedly attacked.

The available information doesn’t yet clarify what exactly burned at Tsumbulova or how much of the facility was affected. There is no public confirmation of specific systems or stockpiles destroyed on the ground. The combination of reported Ukrainian drone strikes and multiple, clustered fire detections over a known drone complex, however, points to more than a routine range event.

If launch infrastructure, storage areas, or command elements at Tsumbulova were hit, Russia could face short-term disruptions in how it stages and sends out Geran-2, Geran-4, and Geran-5 drones toward Ukraine. The site’s scale and recent build-out have made it a central node in Russia’s long-range one-way attack drone operations.

For nearby civilian areas in Oryol Oblast, strikes on a large military test site increase the chance of secondary explosions and debris, even if the main targets are military. The available reports do not detail any civilian casualties or off-site damage.

Key signals in the coming days will include any Russian footage of continued launches from Tsumbulova, changes in the pace or origin points of Geran strikes on Ukraine, and new satellite imagery that might clarify how extensive the fires were within the facility.
