The E-Systems XQM-93A aircraft is part of the US Air Force’s early 1970s “Compass Dwell” program evaluating the possibility of high-altitude Unmanned Autonomous Vehicles (UAV) for use in the Vietnam War. As one of the competitors for “Compass Dwell,” LTV (later E-Systems) introduced its piloted L450F. The next prototype, the E-Systems ZQM-93A, could be piloted or unmanned. Unfortunately, the goal of cutting off supplies on the Ho Chi Minh Trail with unmanned eyes in the sky never materialized when the “Compass Dwell” program ended.
