The Stalker XO-15 MAX is a Ukrainian 15-inch fiber-optic FPV strike drone from TechEx, advertised as a NATO-coded, Ministry of Defence-certified Stalker-family model with a 20 km range, 2 kg payload, and a control link intended to keep working in heavy electronic-warfare conditions.
In the 2014 Russia-Ukraine War, Ukraine's Ministry of Defence and Online.UA describe Stalker-series drones, including the XO-15 branch, as combat-used by Ukrainian units for tactical-depth strikes; public sourcing directly documents Stalker/XO-15 employment rather than an XO-15 MAX-specific strike.
Role detailsTechEx presents the XO-15 MAX as the extended-reach member of the larger Stalker branch: a fiber-optic FPV strike drone with a 20 km listed range, 2 kg payload, and a layout intended for missions where radio control is vulnerable to jamming.
| Area | Source-backed detail |
|---|---|
| Control link | The official product page lists fiber-optic control, and the Ministry of Defence describes Stalker fiber control as useful in heavy electronic-warfare conditions. |
| Reach | TechEx lists a 20,000 m maximum flight range for the XO-15 MAX, beyond the 15 km figure associated with the baseline XO-15 branch in public Stalker reporting. |
| Payload layout | The XO-15 MAX page lists a 2 kg maximum payload, options for thermal imaging and target acquisition, and a universal mounting location for the warhead. |
| Launch tempo | Published specifications list 10 minutes for deployment and packing, plus 6 minutes to arm the drone. |
| Family evidence limit | Public conflict-use sources identify the Stalker series and XO-15 branch in Ukrainian combat use; they do not separately document a named XO-15 MAX combat sortie. |
TechEx's Stalker fiber-optic FPV family is organized around compact 10-inch and larger 15-inch branches, with MAX pages presenting higher-end configurations inside the same product line.

The XO-15 MAX sits in TechEx's larger Stalker branch: the family evidence separates 10-inch forward-position drones from 15-inch models intended for longer reach and heavier payloads.
| Model | Catalog link | Family role |
|---|---|---|
| Stalker XO-10 | | Baseline 10-inch model for forward-position strikes against vehicles, equipment, and personnel. |
| Stalker XO-10 MAX | | Compact MAX configuration with a published 15 km range, 1.5 kg payload, and fast setup figures. |
| Stalker XO-15 | | 15-inch model for support-zone and tactical-depth targets such as artillery, air defense, command posts, and EW systems. |
| Stalker XO-15 MAX | Current record | Larger MAX configuration that TechEx lists with a 20 km range, 2 kg payload, and the same fiber-optic mission logic. |
