The Loitering Munition is so called because it gets fired off into the sky and then lurks about for up to ten hours. At any time, it can be ordered to suddenly plunge down onto a target and explode. If no target crops up, it will self-destruct before running out of fuel. According to the British Army, targets for the Fire Shadow lurker-bombs would be found by various means, including the use of the future “Watchkeeper” surveillance drone.
So let’s see: if this thing finds a target, white-hot fragments rain down from the sky at ultra-high speed and destroy it; if it doesn’t find a target, red-hot fragments rain down from the sky at somewhat lower speed, covering a random area known to be target-free. Great.
