Russia’s Geran-4 Jet Drone Exposed: Chinese Telefly Turbojets Power Moscow’s Newest Strike UAV

Ukraine’s Defence Intelligence Directorate (GUR MO), reporting cited by Defence-UA and Kyiv Post, traces both engine types inside the Geran-4 to Telefly Telecommunications Equipment Co., Limited — a Chinese manufacturer whose turbojets now power Moscow’s newest strike UAV family.
- Engine: Telefly LX-WP-160 (primary) and Telefly TF-TJ2000A — Chinese turbojets
- Speed: ~500 km/h (~310 mph)
- Range: ~450 km (280 miles)
- Warhead: 50 kg HE or thermobaric / 90 kg thermobaric
- Production target: Up to 500 per month
- First combat: January 2026 (sighting); May 2026 (serial deployment)
Why Russia Built the Geran-4
Russia has deployed Geran-2 drones in mass wave attacks since late 2022. Ukraine’s intercept network — FPV patrols, electronic warfare, radar webs — steadily raised the interception rate against slow propeller-driven drones. The Geran-4 is Moscow’s answer: a turbojet variant flying at three times the speed, cutting available intercept time from minutes to seconds.

China’s Role: The Telefly Engines
Both engine types are manufactured by Telefly Telecommunications Equipment Co., Limited. The TF-TJ2000A had already been identified in Geran-5 variants. Their export to Russia under Western sanctions constitutes documented dual-use technology transfer.
| Parameter | Geran-2 | Geran-4 |
|---|---|---|
| Propulsion | MD-550 propeller (Chinese) | Telefly LX-WP-160 turbojet (Chinese) |
| Speed | ~185 km/h | ~500 km/h |
| Range | 1,000–2,500 km | ~450 km |
| Warhead | 40 kg HE | 50–90 kg HE or thermobaric |
| Key advantage | Long range, low cost | High speed, hard to intercept |
Eastern Flank Context
According to Meta Defense, if Russia reaches 500 Geran-4 units per month alongside Geran-5 production, Ukraine’s intercept architecture risks saturation by both volume and speed. NATO Eastern Flank air-defense planners now face a drone threat category that did not exist in doctrine two years ago: turbojet loitering munitions at cruise-missile-equivalent speeds at a fraction of the cost.
Why It Matters for Turkey
- STM KUZGUN with 1,000+ km range already exceeds Geran-4’s 450 km envelope — Turkey can credibly field a comparable class of weapon.
- ASELSAN’s ÇAFRAD and KORAL EW systems are being refined for high-speed, low-observable target profiles that Geran-4 directly exploits.
- Turkey’s TB2 and TB3 deliveries to Ukraine become more strategically significant as Geran-4 enters serial deployment.
Frequently Asked Questions
What is the main difference between Geran-2 and Geran-4? Propulsion: Geran-2 uses a slow propeller for long range; Geran-4 uses a Chinese turbojet optimized for speed that defeats current intercept networks.
Who makes the Telefly engines? Telefly Telecommunications Equipment Co., Limited — a Chinese manufacturer. Their export to Russia is documented dual-use transfer under Western sanctions.
Is 500 per month significant? Yes. Ukraine currently intercepts ~30–50 drones per day. Adding 500 Geran-4s per month creates genuine saturation pressure by both volume and speed.
Bottom Line
The Geran-4 is Russia’s clearest proof yet that Chinese industry is an active partner in Moscow’s war machine. With Telefly turbojets, a heavier warhead, and a hardened airframe, it represents a generational step beyond the Shahed-136 baseline — tuned specifically to defeat the intercept architecture Ukraine and NATO spent two years building.
