**Deck**: NASA fire data show multiple large fires at the Tsumbulova Test Site in Oryol Oblast after Ukrainian drone attacks on a range used to launch Geran-2, Geran-4, and Geran-5 drones.

Fires broke out at Russia’s Tsumbulova Test Site in Oryol Oblast after Ukrainian drone strikes, hitting a facility described as the country’s largest launch site for Geran drones.

NASA’s FIRMS satellite fire‑monitoring system detected multiple large fires at the range following the Ukrainian attacks. The Tsumbulova site is used to launch Geran‑2 drones as well as newer Geran‑4 and Geran‑5 jet‑powered drones, which Russia has used extensively for long‑range strikes on Ukraine.

Open‑source reporting characterizes Tsumbulova as Russia’s biggest drone launching site. It has expanded rapidly over the past two years as Moscow increased its reliance on Geran systems, and it has already been the target of several earlier Ukrainian attacks. The latest FIRMS data point to a cluster of fires in and around the complex after Ukrainian drones reached the area.

There is no detailed public assessment yet of physical damage inside the test site. Without ground imagery, it remains unclear which structures or stocks were hit, or whether launch pads, storage areas, or fuel facilities suffered lasting losses. The timing and location of the thermal signatures, however, match reports of Ukrainian drone activity against the range.

For Russian personnel who assemble, program, and launch drones from Tsumbulova, the strikes show that a site once considered a rear‑area facility now sits inside Ukraine’s reach. That shift can force changes to how equipment is stored and protected and may disrupt routine operations while damage is surveyed.

Any serious disruption at Tsumbulova would matter for Russia’s wider drone war. Geran drones are central to its campaign against Ukrainian energy, logistics, and urban infrastructure. Large fixed launch sites are harder to conceal than mobile platforms and present valuable targets. If parts of Tsumbulova are offline, Russia may need to alter flight paths, route launches through other locations, or accept a slower tempo.

The attack fits into a broader pattern of Ukrainian strikes on Russian infrastructure supporting the war. On the same night, Ukrainian mid‑range drones attacked energy infrastructure in Donetsk City, causing power outages in parts of the city. Ukrainian forces have framed such actions as a response to Russian strikes on Ukrainian power and logistics nodes.

Key signals to watch now include whether Russian Geran launch activity drops or shifts geographically, new satellite imagery revealing repair or construction at Tsumbulova, and any signs that Russia is dispersing drone operations to smaller sites to limit the impact of future strikes.
