Even with drones already dominating the skies, neutralizing adversaries and covertly collecting data, new research is still underway on the generation of pilotless planes to come.
And the United States isn't the only country interested in developing long-range and lethal drone technology.
Groups of European and Asian nations — allies and former adversaries alike — are busy investing in next-generation unmanned aerial vehicles of their own.
These UAVs — some in development, some testing, and some already in service — are part of a global competition to gain aerial superiority.
But right now, only a handful of companies are working seriously on this next wave of drones. Some are researching independently, some are working for a single nation, others are working for a dozen.
Here's the top tier of next-gen drone tech.
Northrop Grumman X-47B
The strike fighter was developed by Northrop Grumman as part of a research contract awarded in 2007. Look for these in use for the Navy, which hopes to use them as carrier-based drones. Tests for that begin in 2013.
National Origin: United States
Intended Customers: United States Military and clandestine services
Status: In development, used by Navy for testing
Cruise Speed: around 420 mph, (Mach 0.55)
Wingspan: 62 ft
Range: At least 2,400 miles
Boeing Phantom Ray
The project was hatched in 2007, and was carried out in utmost secrecy. The drone's development was funded internally, without funding from the government of military. The Boeing Phantom Ray, which precedes the development of the Phantom Eye, is Boeing's planned ground strike and surveillance drone.
National Origin: United States
Intended Customers: United States Military and clandestine services
Status: In development, maiden flight April 27, 2011
Cruise Speed: 614 mph (Mach 0.8)
Wingspan: 50 ft
Range: 1500 miles
General Atomics Predator C Avenger
This drone is incredible. The Predator line of drones currently in constant use in Afghanistan and Iraq were the first ever weaponized UAVs. This model follows up with a reduced heat signature and speed boosts. It boasts an upgraded "quick response armed reconnaissance capability" from its predecessors.
National Origin: United States
Intended Customers: United States Military and clandestine services
Status: Deployed. Maiden flight April 4, 2009
Max Speed: 460 mph
Wingspan: 66 ft
Range: 20 hours
