The EB-66Es were converted from RB-66B and designed for the Electronic Counter Measures (ECM) mission. The aircraft designed was based on the EB-66B modifications but incorporated much more extensive updates to the electronic emission detection, surveillance and jamming equipment. The photo reconnaissance equipment was removed to make room for the additional ECM equipment.
Thirty-four aircraft were modified and served in Southeast Asia beginning in the late 1960s. By the mid-1970s, the EB-66Es were replaced by more advanced aircraft, including the McDonnell Douglas F-4G Wild Weasel.
