at Wright-Patterson AFB, Ohio, in December 1975 as part of an overall consolidation of large test and evaluation aircraft, the ARIA fleet underwent numerous conversions - including a re-engining that changed the EC-135N to the

Over its thirty-two year career, the ARIA supported the United States space program, gathered telemetry, verified international treaties, and supported

(SAC) began the Looking Glass mission on February 3, 1961 and Looking Glass aircraft were continuously airborne 24 hours a day for over 29 years, accumulating more than 281,000 accident-free flying hours. On July 24, 1990, "The Glass" ceased continuous airborne alert, but remained on ground or airborne alert 24 hours a day. The EC-135A flew the Command Post mission until EC-135C were delivered
starting in 1963. The aircraft were delivered to Offutt AFB and as well as one aircraft to each of the Stateside Numbered Air Force Headquarters - Second Air Force at Barksdale AFB, LA; Eighth Air Force at Westover AFB, MA; and Fifteenth Air Force at March AFB CA. EC-135's flew all the missions except one, when an E-4B was tested on a operational mission, flying a double sortie as the replacement aircraft could not launch due to weather. About a week after the flight, Washington deleted the funds for additional E-4 aircraft.
