EC-121D Constellation walkaround photos

The initial radar Constellations for the Air Force were the ten RC-121Cs, followed up by 72 RC-121Ds with wingtip tanks, these becoming EC-121Ds in 1972. Most were upgraded with new computers as EC-121Hs; some H-models and other airframes were reworked as EC-121Ts. The T-models lacked the height finder set and associated radome; some EC-121Ts hung on in service until 1978, when they were finally retired with the arrival of the E-3 Sentry.
