PIRANHA SPR is a Ukrainian stationary counter-UAV electronic-warfare system from Piranha Tech. Official materials describe a directional jammer that can work with external cueing, automatically orient antennas, and suppress UAV links across selected frequency bands.
Piranha Tech's 2025 catalog lists SPR as a stationary counter-UAV system and states that Piranha Tech equipment is actively used by Ukraine's Defense Forces in the 2014 Russia-Ukraine War; it does not identify a specific SPR unit or engagement.
Role detailsPiranha Tech describes SPR as a stationary directional jammer for countering unauthorized UAV flights and civilian drones. The cataloged setup emphasizes external antennas, selected frequency channels, and a control case with built-in computing.
| Function | Documented detail | Page context |
|---|---|---|
| Suppression | Directional radio interference across up to 8 channels from 400-5900 MHz. | Positions SPR as a fixed-site electronic-warfare system rather than a kinetic interceptor. |
| Cueing | Can work with systems that provide target direction or target coordinates. | Supports integration with external detection or observation layers when available. |
| Antenna control | External directional antennas with automatic steering through specialized software. | Lets the system concentrate jamming energy toward a detected direction instead of radiating evenly. |
| Protection | VSWR monitoring and overheating protection. | Documents safeguards for RF equipment and antenna/cable faults. |
| Power and climate | 24/28 V DC internal power or 220 V 50 Hz AC external power; -20 to +40 C and 5-95% humidity. | Indicates a site-powered system with environmental limits stated by the manufacturer. |
The 2025 Piranha Tech catalog lists SPR as a stationary UAV counter system with up to 8 suppression channels from 400-5900 MHz and a total output power up to 400 W.

Piranha Tech places SPR in a wider Ukrainian counter-UAV product line that includes fixed-site, portable, and dome-protection electronic-warfare systems.
| Cataloged system | Documented role | Relationship to SPR |
|---|---|---|
 | Five-channel stationary jammer | Shares the fixed-site anti-drone mission with a smaller channel package. |
 | Portable counter-UAV jamming rifle | Moves the same manufacturer line into a carried field device. |
 | Omnidirectional dome-protection system | Provides an area-protection counterpart to SPR's directional jamming model. |
 | Backpack dome-protection system | Represents a smaller mobile dome-protection branch of the same counter-UAV family. |
 | Panel direct-action counter-UAV system | Another HAD-5 configuration in the product family rather than a direct SPR variant. |
