An Eye in the Sky

Phantom Eye is a liquid hydrogen-fueled, high-altitude and long-endurance unmanned aircraft system for persistent intelligence, surveillance and reconnaissance and communications missions. The demonstrator aircraft is capable of maintaining its altitude for up to four days while carrying a 450-pound payload. Typical payloads include multiple sensor packages for monitoring, tracking and communications. A full size Phantom Eye variant is designed to stay aloft for up to ten days and carry a payload of 2,000 pounds.

Phantom Eye Quick Facts

  • The Phantom Eye began as internally-funded, but the Missile Defense Agency assisted the program with a $6.8 million contract.
  • This advanced unmanned aerial system is a natural evolution of Boeing’s earlier success with the piston-powered Condor.
  • The Condor set several records for altitude and endurance in the late 1980s.
