The M11 was created through a joint venture between Barretta and Raytheon with the goal of designing a dedicated anti-drone weapons system. The twin 20mm cannons had a rate of fire of 2,800 rounds per minute between them and fired the specially designed FF20 round. The FF stands for Flash Fragmentation, as the round was designed to emit a powerful flash of light covering the Ultra Violet to Infra Red spectrum while also exploding shrapnel at its targets. This flash was designed to blind the cameras of drones making it harder for them to maneuver and use their targeting systems. The U.S. Naval version of the M11 designated M11-23A1 used a short wavelength AESA radar to identify threats within about 8 miles. Within 4 miles its smaller targeting radar would lock the highest threat and engage. The gun was also equipped with a laser range finder and an IR camera for manual targeting though once the FF20 rounds started exploding these became less effective.
