Turkish defence company STM has announced the successful field integration of its newly developed RF Seeker Payload into the KARGU loitering munition. Designed to detect and neutralize RF-emitting systems, the enhanced KARGU has been tested specifically against FPV drones, which are among the most prominent threats in modern combat environments.

 

 

The RF Seeker-equipped KARGU represents a significant step in autonomous warfare and electronic countermeasures. Developed with domestic capabilities, the system is capable of detecting RF signals across a broad frequency spectrum and autonomously guiding the munition to enemy transmissions.

“KARGU with integrated RF Seeker is more than just a drone,” said STM General Manager Özgür Güleryüz. “It is a fully autonomous, smart electronic warfare solution developed by STM engineers to detect, track, and eliminate electromagnetic threats in the field.”

Güleryüz emphasized the cost-effectiveness and adaptability of the system, which uses software-defined radio (SDR) architecture for future upgrades. “It can detect a wide range of RF signals and guide KARGU toward RF-emitting targets for effective, low-cost neutralization,” he noted.

During recent field tests, the upgraded KARGU detected the location of a hostile FPV drone pilot using both internal and external antennas. “Under operator control, KARGU performed a precision dive and eliminated the target,” Güleryüz explained, calling the system “a smart and cost-effective deterrent against the rapid spread of FPV drone threats.”

Beyond FPV drones, STM’s technology enables KARGU to disrupt high-value enemy systems such as radars, air defences, and electronic warfare platforms. “Our system enables KARGU to blind and neutralize high-value enemy assets… with a far more economical solution,” Güleryüz added.

The RF Seeker Payload offers flexible integration with mini and micro-class UAVs, operating effectively in both GNSS-enabled and GNSS-denied conditions. Its capabilities include autonomous RF-based guidance, direction finding, target frequency scanning, and identification of both hostile and friendly RF emissions.

Key specifications of the system include a 10-kilometer operational range, 25-minute endurance, and target detection at altitudes between 50 and 500 meters. STM is currently showcasing the RF Seeker-Equipped KARGU at the IDEF 2025 defence industry exhibition.
