In 1954 the Lockheed EC-121 Warning Star was introduced and operated until 1978. These
aircraft were used as airborne early warning radar surveillance to work in conjunction with the
DEW Line (Distant Early Warning) Line. The USAF used these aircraft in Vietnam as electronic
sensor monitors and to detect enemy aircraft activity as well as a few other operations. These
aircraft were the forerunners to today’s E-3 Sentry AWACS. The USAF aircrews used the
nickname “Connies”, a play on the word Constellation.

In April 1965 as the build up in SEA continued the 552nd AEW&CW (Airborne Early Warning and
Control Wing) was deployed to assist in operations against the North Vietnamese. This portion of
the operation was called the Big Eye Force but would later be changed to College Eye Task
Force. On October 24, 1967 EC-121D AF serial 53-0555 (nicknamed Triple Nickel) became the
first airborne radar aircraft to guide an F-4C to a successful kill of a MiG-21 and is on display at
Wright Patterson AF in Dayton Ohio.
