With a range of 1,150 miles, and the ability to fly at altitudes of 50,000 feet (higher than civilian commercial Airplanes), the MQ-9 Reaper system is an “armed, multi-mission, medium-altitude, long-endurance” remotely piloted aircraft designed primarily for offensive strikes.

Given its significant loiter time, wide-range sensors, multi-mode communications suite, and precision weapons — it provides a unique capability to perform strike, coordination and reconnaissance against high-value, fleeting, and time-sensitive targets,”

At 4,900-pounds per unit, the drone can also conduct surveillance, assist in search and rescue missions, and allow US forces to “conduct irregular warfare operations.”

With near absolute silence during flight, Its' a significant acknowledgment of the rapidly evolving, and expanding, role of Remotely Piloted Aircraft by the US Air Force during military operations, and when at War.
