The Stalker XO-15 is a Ukrainian 15-inch fiber-optic FPV strike drone from TechEx, built to carry heavier payloads into support-zone targets while keeping control through a tethered optical link in electronic-warfare-heavy conditions.
In the 2014 Russia-Ukraine War, Ukraine's Ministry of Defence says the Stalker XO-15 is actively deployed by combat units for support-zone and tactical-depth strikes against command posts, artillery, air-defense, and electronic-warfare targets.
Role detailsThe XO-15 is the larger standard Stalker strike model, combining a 15-inch FPV airframe with fiber-optic control for attacks beyond the immediate contact line.
| Area | Source-backed detail |
|---|---|
| Control link | TechEx lists the XO-15 with a fiber-optic module, cable spool, and battery unit; Ukraine's Ministry of Defence frames the Stalker series as resilient in dense electronic warfare. |
| Target set | The Ministry of Defence identifies the XO-15 for support-zone and tactical-depth targets including command posts, artillery, air-defense systems, and electronic-warfare assets. |
| Payload layout | TechEx lists a universal warhead mounting location, and Online.UA describes the Stalker layout as keeping the upper frame open for combat loading. |
| Range and endurance | TechEx lists a 15,000 m maximum range, 15 minutes endurance with maximum payload, and 20 minutes without payload. |
| Setup and sensing | Published TechEx specifications list 10 minutes for deployment and packing, 6 minutes for arming, and a 150 m target detection and recognition range. |
TechEx's Stalker fiber-optic FPV line is built around 10-inch and 15-inch models, with MAX variants extending the same control-link concept for different payload and range needs.
