Stellarion was set to test its drones in front of American soldiers at a competition organized by the Pentagon at Camp Grayling,

The investigation found that Russian designs for rocket-launched drones likely helped shape weapons China unveiled in 2025 and that Russian wind tunnels kept testing aircraft models for China's top arms maker after the invasion of Ukraine.
