Gray Butte, CA: The General Atomics drone base, way out in the wastelands of the Mojave Desert ... today ranks as possibly the largest private drone base in the United States. General Atomics took the base over in 2001 and converted it into a testing and quality control facility for its drone fleet. This is where the company tests experimental drone technology--like the newfangled stealth bomber jet drone. But mostly the base is where General Atomics techs assemble and test their Predator and Reaper drones before breaking them down again and shipping them to eager customers in the Air Force, Border Patrol, National Guard and the CIA. The Guardian estimated that U.S. armed forces had about 250 General Atomics drones in 2012. And a good number of them first came through Grey Butte. [The] brothers who make them: Linden Stanley and James Neal Blue, the mysterious Blue brothers who own and run General Atomics. General Atomics does not disclose its financial information, but stats gleaned from public data show that they took in just under $5 billion from U.S. taxpayers from 2000 to 2009. Current annual revenue is estimated to between $600 million and $1 billion, with about 80 percent coming from government defense contracts. Today, General Atomics dominates 25% of the UAV market--a market that will only keep getting bigger and bigger.
