The Gray Eagle is the Army's specific advanced version of the iconic Predator drone, which has a distinctively larger head housing more sensors than its predecessor. The Eagle can carry
four hellfire missiles, twice as many as the Predator, and it can do so 4,000 feet higher in the air while traveling about 50 mph faster. To do all this, the Eagle loses some endurance speed, lasting a maximum of 25 hours in the air, well below the Predator's 40. And the Eagle hasn't been without its growing pains, including faulty circuits and an early underwhelming performance. The Gray Eagle is still a young drone -- first deployed in Afghanistan in 2012 -- and working from a drone-specific airbase should let the Army better understand and improve its vehicle.
