Satellite imagery from US spatial intelligence firm Vantor has unveiled significant expansions at Russia's Tsimbulova drone base in the Oryol region, approximately 100 miles from the Ukrainian border. The images, dated April 22, show four launch rails, two of which have been extended to 85 meters (280 feet) in length, specifically designed to accommodate newer generations of jet-powered Geran drones.
Infrastructure Investment for Advanced Drones
Construction on the extended rails began in late December 2025, with additional shorter rails completed in late March or early April 2026, according to open-source investigator Kyle Glen. The shorter rails are intended for older Geran-3 and Geran-4 variants, while the longer rails support the advanced Geran-5 models, which resemble traditional cruise missiles in design.
The extended launch rails are a clear indication of Russia's commitment to enhancing its drone capabilities, particularly for one-way attack drones that have been extensively used against Ukrainian civilian infrastructure since 2022.
The Geran series, derived from Iran's Shahed-136, has evolved from propeller-driven models to jet-powered variants capable of high-speed strikes. These drones are launched using rails to achieve initial acceleration before their engines take over, enabling them to carry explosive warheads and detonate on impact.
Strategic Implications
Tsimbulova is one of only two known bases equipped to support the newer Geran drones, with the other located in the occupied Donetsk region. Both sites have undergone recent expansions, including additional launch positions and storage facilities. Despite being miles from the front lines, Ukraine has targeted these bases in response to Russia's escalated drone attacks, which saw nearly 16,000 launches in the first three months of 2026 alone.
In response, Ukraine has ramped up production of interceptor drones, with President Volodymyr Zelenskyy claiming a daily output of at least 2,000 units. These interceptors have become a priority for Kyiv and have garnered attention from NATO allies and US partners.
