It carries multiple sensors including both high-definition day modes and night infrared modes. The MX-10 is currently operational for twelve nations worldwide on the S-100 including Naval Shipborne customers leading to a low risk, proven solution.

Mike Greenley, group president of MDA said, “MDA is a global leader and trusted partner in UAS surveillance services in challenging, complex and hostile environments.
