About Us
MyDefence North America is a U.S.-based provider of advanced Counter-Unmanned Aircraft Systems (C-UAS) technology dedicated to protecting American personnel, facilities, and airspace from unauthorized and hostile drones.
As drone use continues to expand across the country, so do the risks to military installations, federal and state government facilities, critical infrastructure, airports, border operations, and major public venues. The rapid advancement of commercial and modified drone technology has created new and complex threats that require immediate detection and response.
At MyDefence North America, we are committed to ensuring that those responsible for protecting the United States have the situational awareness and technological advantage needed to stay ahead of emerging drone threats.

Oklahoma City serves as the foundation of MyDefence North America’s U.S. manufacturing operations, supporting domestic production, strengthening supply chain reliability, and meeting federal acquisition requirements. Producing in the United States ensures responsiveness to customer needs while supporting American jobs, engineering talent, and industrial capability.
Our presence in Oklahoma places us within one of the nation’s strongest aerospace and defense ecosystems and in close proximity to key U.S. Army partners.
Committed to U.S. Security
MyDefence North America is dedicated to strengthening and engineering advanced solutions for the demanding operational environments faced by U.S. military personnel, federal agencies, state and local law enforcement, and critical infrastructure operators.
