Boeing YQM-94A Compass Cope B

The YQM-94A was a high altitude, long-range, Remotely Piloted Aircraft (RPA) tested in the 1970s. It was designed for long-endurance photographic reconnaissance and electronic surveillance missions.

Piloted from the ground, the YQM-94A received guidance signals through a radio link. A television and other electronic equipment aboard Compass Cope sent in-flight data back to the ground-based pilot. The YQM-94A took off and landed from conventional runways.

The first prototype YQM-94A made its initial flight in June 1973 but was destroyed in a crash in August 1973. The vehicle on display is the second prototype, and it flew for the first time in November 1974. On one flight, this Compass Cope flew for 17 hours, 24 minutes at altitudes of more than 55,000 feet.

After the USAF canceled the program, this YQM-94A was retired to the museum in September 1979.
