General Atomics MQ-9 Reaper – Cost: $56.5 Million

The General Atomics MQ-Reaper is unique from the other aircraft we’ve discussed so far in the way that it is piloted remotely. Equipped with a whole array of information-collecting devices, including a monochrome daylight TV camera, it is typically deployed for reconnaissance missions but could also perform strikes.

It is actually the primary offensive strike unmanned aircraft the United States Air Force uses, and with good reason. The MQ-9 Reaper can go on 24-hour missions thanks to the addition of external fuel tanks that can hold up to 1,300 pounds of fuel.
