The U.S. Army plans to use Raytheon’s Coyote unmanned aircraft and the KRFS radar against enemy drones on the battlefield, Raytheon officials said in July. The Coyote small unmanned aerial vehicle (UAV) is designed to be guided by the KRFS radar, and to explode next to enemy drones, effectively acting as a guided missile. The Coyote is a lightweight expendable UAV and is tube-launched, eliminating the need for a runway. It can be launched from ground, air or naval units, and can be networked to operate in swarm attacks to be used for surveillance in addition to strike attacks. The Coyote also is used for hurricane tracking by the National Oceanic and Atmospheric Administration, the agency responsible in the United States for severe weather monitoring.
