What the August 15, 2026 Satellite Imagery Shows

The Ukrainian monitoring channel Strategic Aviation published satellite images on August 15 that document the final stage of a rapid construction project at the Tsymbulova (also spelled Tsimbulova) drone port. The key findings include:

• 16 launchers fully deployed: The base now has 10 launch pads purpose-built for the Geran-5 and six for the Geran-4, all completed in roughly one month starting in July 2026 .
• More than 100 drones stored in the open at the facility, indicating an active, sustained strike rhythm .
• Nearly 100 solar panels installed on site, likely to power launch infrastructure .
• Launch rails extended to approximately 85 meters — roughly three times longer than those used for propeller-driven Geran-2 drones — to accommodate the higher takeoff speed of jet-powered UAVs .
• Construction of these extended rails began in late December 2025; the site was first identified for jet-powered Geran-3/4 and Geran-5 operations in April 2026 .

Production Milestones: Geran-4 and Geran-5

The infrastructure expansion at Tsymbulova is matched by a large-scale production ramp-up at a facility in Yelabuga, within the Alabuga Special Economic Zone in Tatarstan . Ukraine's Main Intelligence Directorate (HUR) reported in mid-August 2026 that:

• ~3,000 Geran-4/5 jet drones per month are now being produced, up from earlier estimates of 500 per month in May 2026 .
• Jet drone output has surpassed Geran-2 production, with the HUR estimating 3,000 Geran-4/5 and about 2,800 Geran-2 produced per month as of August 2026 .
• Russia's total monthly drone output across all types was about 5,500 as of March 2026, according to the Center for Strategic and International Studies .
• Russia planned to produce 11,000 strike drones in August 2026 across all variants, including Geran, Harpy, and Gerbera .
• Moscow has ended production of the earlier Geran-3 jet drone, consolidating around the faster Geran-4 and Geran-5 models .
• Jet-powered drones now make up 25–50% of combined strikes on Ukraine, up from near zero a year earlier .

Engine Sourcing: Total Dependence on Chinese Turbojets

Russia's jet-powered drone surge has a clear bottleneck: the engines. According to multiple Ukrainian intelligence assessments, Russia cannot domestically produce the turbojet engines needed and relies entirely on supplies from China .

• The Geran-4 uses Chinese Telefly engines — specifically the Telefly LX-WP-160 (160 kgf thrust) and the Telefly TF-TJ2000A (200 kgf thrust). The LX-WP-160 is already discontinued, but stockpiles and continued supplies of the TF-TJ2000A sustain production .
• These engines give the Geran-4 a top speed of roughly 500 km/h, compared to the propeller-driven Geran-2's ~180 km/h, and a range of approximately 450–850 km .
• The earlier Geran-3 used a Chinese Telefly engine with 40 kgf thrust; the Geran-4 swapped the Geran-2's piston engine for the Chinese turbojet while retaining a similar airframe .
• Each turbojet engine costs between $35,000 and $40,000, and while officially marketed as civilian products, they are supplied to Russia at scale with implied Chinese government consent .
• This creates a strategic vulnerability: any disruption to the supply of Chinese jet engines would directly constrain Russia's drone production surge .

Jet Engines Adapted to Other Models: The BM-35

The jet-engine conversion is not limited to the Geran family. Russia is now fitting jet engines to the BM-35, a budget mid-range strike UAV previously powered by a two-stroke gasoline engine .

• The jet-powered BM-35 can reach 350 km/h, specifically to outrun Ukraine's interceptor drones .
• Ukrainian presidential adviser Serhii Beskrestnov (callsign "Flash") confirmed that as Ukrainian interceptors improved, Russia began fitting jet engines not only to Shahed-type drones but also to budget mid-range strike UAVs like the BM-35 .
• The BM-35 was previously a relatively slow, sub-200 km/h drone, vulnerable to Ukrainian FPV interceptors and electronic warfare . The jet upgrade is a direct countermeasure.

Broader Strategic Picture

Russia is executing a deliberate, rapid shift from slow propeller-driven drones to a family of jet-powered UAVs. The logic is straightforward: Ukrainian interceptors — both electronic warfare jammers and kinetic FPV drones — had become highly effective against the ~180 km/h Geran-2. The jet-powered Geran-4 (500 km/h) and Geran-5 (even faster, described by some sources as a "missile-drone") are far harder to intercept .

The Tsymbulova base expansion physically enables large-scale launch operations close to the Ukrainian border, while the Yelabuga plant scales serial production to meet the new monthly targets. However, the entire enterprise rests on a fragile foundation. Every jet drone in this new fleet depends on Chinese Telefly turbojets that Russia cannot yet manufacture itself . Without those engines, the production lines and launch pads at Tsymbulova would serve no purpose.
