Before the General Atomics Predator and Reaper drones defined the skies of the War on Terror, the modern drone age began, modestly and without fanfare, in the early 1990s. Designed by Israel Aircraft Industries and in the United States maintained by Northrop Grumman, the MQ-5 Hunter was canceled in 1996. But soon enough war called it back. Flown in support of American forces in Kosovo in 1999, the Hunter remained active ever since. After 22 years in military use, it’s finally retiring from service.
