Proteus is a twin-turbofan, high-altitude, multi-mission aircraft powered by Williams International FJ44-2E engines. It is designed to carry payloads in the 2,000 lb class to altitudes above 50,000 ft and remain on station up to 14 hours. Heavier payloads can be carried for shorter missions. It is intended for both piloted and UAV missions. Missions for Proteus include telecommunications, reconnaissance, atmospheric research, commercial imaging, and space launch. 

The Proteus is designed with long wings and a low wing loading needed for efficient high altitude loiter. It excels in stability and low noise.
