US Air Force Deploys Vehicle-Mounted Jammers to Counter Drone Threats

CounterUASWorld Summary

A US Air Force Pararescue squadron has fielded four vehicle-mounted Cipher electronic warfare systems from RAZOR-01 to counter evolving unmanned aerial system (UAS) threats. The modular jammer features an 18-channel architecture, allowing operators to dynamically switch transmission pathways in the field and address drones that rapidly change operating frequencies. Manufactured in Arizona without restricted components, Cipher was developed using direct combat feedback from Ukraine against Russian drone tactics. The deployment comes amid rising US investment in counter-UAS capabilities, with the US Army’s FY2027 procurement request increasing to $994 million from $596 million in FY2026.
