Performance. precision. persistence.

Meet Proteus, a twin-turbofan, high-altitude, multi-mission beast built to push the limits of endurance and innovation. Powered by Williams International FJ44-2E engines, Proteus was designed to lift heavy payloads above 50,000 feet and stay on station for up to 14 hours straight — that’s strength, stamina, and altitude that few can match.

With missions ranging from telecommunications and reconnaissance to atmospheric research, commercial imaging, and even space launch support, Proteus is a true shapeshifter in the sky. Its long, slender wings and low wing loading make it ultra-efficient at altitude, while its rock-solid stability and whisper-quiet presence give it an edge that’s as stealthy as it is powerful.

Proteus isn’t just an aircraft, it’s proof of what happens when you fuse performance, precision, and persistence at the edge of the atmosphere.
