The RQ-4 Sentinel is a Paternian unmanned aerial vehicle, designed by Paternian Defense Industries. It is designed for reconnaissance, surveillence, targeting, and damage assessment. A successor to the RQ-1 Finch, the RQ-4 features greater endurance, improved reliability, and more powerful sensors. The drone can either take off and land on its own. However, it can be launched from a pneumatic catapult and be recovered by means of flying into a large net or arrestor hook. It can carry up to 35 kilograms of cargo inside, allowing it to transport light cargo such as weapons, ammunition, electronic equipment, medical supplies, and even light rations. While a strike capability was tested, such was never fitted to the aircraft, since the Army had no interest in it; there are many aircraft in the Paternian arsenal that can carry much greater payloads and deliver them more precisely.
