"Delivering this enhanced version of the combat-proven Coyote strengthens our allies' defences against enemy drones", Raytheon Land Warfare Systems Vice President Sam Deneke said in the release. "Block 2 is fast, effective and protects troops on the battlefield".
Powered by a jet engine, the new weapon can be launched from the ground to destroy drones and other aerial threats, the release said.
Defence websites describe the Coyote as a 'kamikaze drone' because the machine is designed to either crash into small, unmanned aircraft or to explode nearby.
The US is developing other anti-drone weapons using lasers or microwave bursts to disable the unmanned aerial weapons.
In February, Raytheon announced that it had completed the first radar antenna for the US Army’s low-tier missile sensor (LTAMDS), designed to detect hypersonic weapons.
