# U.S. Air Force Seeks Drone Defense Cannon

The U.S. Air Force issued a Request for Information (RFI) on September 3, 2026, seeking a ground-based, medium-caliber gun weapon system designed to defend air bases against drones and subsonic cruise missiles. This procurement initiative aims to develop a rapidly deployable, cost-effective, and modular air defense capability capable of countering swarming aerial threats and supporting distributed airfield operations. The RFI reflects the Air Force's strategic shift toward more mobile and layered air defense solutions tailored to evolving unmanned and missile threats.

- This RFI signals emerging opportunities for defense contractors specializing in medium-caliber weapon systems and counter-drone technologies.
- Procurement professionals should note the emphasis on modularity and rapid deployability, indicating potential requirements for adaptable and scalable solutions.
- The focus on defending air bases highlights a priority for protecting critical infrastructure against increasingly sophisticated aerial threats.
- Companies with expertise in integrated air defense and counter-unmanned aerial systems (C-UAS) may find this a relevant market entry point.
