In March 1967, Big Eye was renamed "College Eye Task Force" (CETF) and relocated at Ubon Royal Thai Air Force Base. Because of the complexity of the aircraft and its systems along with the large support group it required, CETF was not welcome at the relatively small Thai bases. It moved to Udon RTAFB in July and to its final station at Korat RTAFB in October 1967. Seven of 26 EC-121s deployed from Otis AFB and arrived at Korat, on the 19th.
