About the General Atomics Aeronautical Systems MQ-9 Reaper

The General Atomics MQ-9 Reaper is the world's most widely deployed armed medium-altitude long-endurance unmanned aircraft, representing a quantum leap over its predecessor, the unarmed MQ-1 Predator. First flown in 2001 and entering service with the U.S. Air Force in 2007, the Reaper was purpose-built for persistent intelligence, surveillance, and reconnaissance missions with strike capability: a hunter-killer that can loiter over a target area for more than 27 hours while carrying precision-guided munitions.

Powered by a single Honeywell TPE331-10 turboprop producing 900 shaft horsepower, the MQ-9 cruises at altitudes up to 50,000 feet and reaches speeds around 240 knots, far exceeding the Predator's performance envelope. Its 66-foot wingspan and modular payload bays accommodate electro-optical/infrared sensors, synthetic aperture radar, signals intelligence packages, and up to 3,750 pounds of ordnance on six external hardpoints. Beyond military strike operations in counterterrorism theaters, the Reaper has found a second career in homeland security and border surveillance.

U.S. Customs and Border Protection operates a dedicated fleet, identifiable by CBP tail numbers and callsigns like MAZE and TROY, patrolling vast stretches of the southern and northern borders, coastal waters, and disaster zones. These unarmed CBP variants carry advanced maritime patrol radar and long-range cameras, providing persistent overwatch that would be prohibitively expensive with manned aircraft.

The type's operational flexibility, from 20-hour maritime patrols to rapid-response wildfire mapping, has made it indispensable for agencies requiring wide-area surveillance without crew fatigue constraints. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
