In October 2022, Raytheon Missiles & Defense, a Raytheon Technologies company, received a $207 million contract from the United States Army for Ku-band radio frequency sensors (KuRFS) and Coyote effectors. The Army plans to equip two of its divisions with KuRFS and Coyote effectors to defend against threats from unmanned aerial systems (UAS).
The KuRFS precision targeting radar and scaled Ku-720 mobile sensing radar provides 360-degree detection, identification and tracking of airborne threats. Coyote Block 2 kinetic and Block 3 non-kinetic effectors can defeat single UAS and swarms at high altitudes and long ranges.
The Army’s Mobile-Low, Slow, Small, Unmanned Aircraft Integrated Defeat System, integrates KuRFS and Coyote effectors with Northrop Grumman’s Forward Area Air Defense Command-and-Control system and Syracuse Research Corporation’s electronic warfare system. This creates a mobile deployed system that provides a complete extended-range defense solution.

Developed for the military, Coyote is a small, expendable UAV that’s air- or ground-launched into environments too dangerous for manned aircraft. The system can fly for more than an hour and up to 50 miles from its host aircraft.
“Weather forecasters are able to better understand storm behavior and improve hurricane models based on the real-time information provided by our Coyotes,” said Thomas Bussing, Raytheon vice president of Advanced Missile Systems. “Coyote UAVs are collecting and delivering robust storm data that could ultimately save lives.”
In 2017, NOAA researchers deployed six Coyote UAVs to track and model Hurricane Maria. Launched from a NOAA WP-3D Orion hurricane hunter aircraft, the Coyotes flew directly into the storm, giving researchers an unprecedented view of Maria.
Traditional weather instruments are dropped from planes and capture only a snapshot of storm behavior, but Coyote’s winged design allowed it to linger and return to key areas of a hurricane to gather more data and transmit it near-real-time to researchers.
“We think unmanned technologies that explore dangerous and difficult to observe regions of the storm may improve our physical understanding, provide enhanced situational awareness and might ultimately improve the accuracy of hurricane intensity forecasts in the future,” said Joseph Cione, a hurricane researcher at NOAA’s Atlantic Oceanographic and Meteorological Laboratory and principal investigator of NOAA’s Coyote project. “The Coyotes we deployed in Hurricane Maria collected critical, continuous observations in the lower part of the hurricane, an area impossible to reach with manned aircraft.”
The Coyote UAV was first deployed in 2014, when NOAA launched four of the systems into Hurricane Edouard, a Category 3 storm. Scientists on board the aircraft collected meteorological data in both the eye of the storm and the surrounding eye wall.
