Personal interest:
The first prototype of this high-altitude, long-endurance UAV, known as Tier II+, flew in February 1998. Redesignated RQ-4A Global Hawk, seven prototypes underwent testing until the 9/11 attack in 2001. At that point, the RQ-4A entered initial low-rate production while still in engineering and manufacturing development.
