The PIRANHA SF-3 is a Ukrainian gun-form counter-UAV jammer from Piranha Tech. Official materials describe a three-channel portable system that applies directional radio interference against selected drone-control, video, telemetry, and geopositioning bands, while battlefield reporting places Piranha-Tech anti-drone guns with Ukrainian units in the 2014 Russia-Ukraine War.
The SF-3 sits in Piranha Tech's portable anti-drone rifle line; WIRED reported Piranha-Tech anti-drone guns with Ukrainian units during the 2014 Russia-Ukraine War, and the official Piranha catalog describes the company's counter-UAV systems as used by Ukraine's Defense Forces.
Role detailsPiranha Tech describes SF-3 as a compact gun-form device for countering unauthorized UAV flights with narrow-angle directional radio interference.
| Attribute | Documented detail | Why it matters |
|---|---|---|
| Channels | Up to 3 simultaneously active channels | Lets the operator cover several selected drone links at the same time. |
| Output power | Up to 50 W per channel | Defines the published power level for the portable jamming package. |
| Weight | Up to 7 kg | Keeps the system in the handheld or short-duration carried-use class. |
| Battery | About 30 minutes with a replaceable battery | Signals that field endurance depends on spare batteries or external support. |
| Jamming effects | Control, video, telemetry, and geopositioning links when configured for the relevant band | Shows the device is meant to disrupt drone operation rather than physically destroy the airframe. |
Piranha Tech places SF-3 inside a wider counter-UAV product line that includes portable, fixed-site, and dome-protection electronic-warfare systems.
| System | Relationship to SF-3 |
|---|---|
 | Backpack dome-protection counterpart for point protection around positions and moving teams. |
 | Another HAD-5 family counter-UAV system in the same manufacturer line. |
 | Fixed-site directional jammer for a more static protection role than SF-3. |
 | Stationary, externally cued counter-UAV system in the Piranha lineup. |
 | Omnidirectional dome-protection system for vehicles, tripods, trailers, or rooftops. |
Piranha Tech says its director and co-founder had been developing electronic-warfare equipment since 2014.
