Several Tu-154M/Ds (Type I/II/III?) have been converted into EW aircraft by PLAAF, even through they are disguised under the cover of a civilian China United Airline registration (shown here is B-4138). Developed from Type I ELINT aircraft, Type III features a canoe shaped fairing under the fuselage which has been speculated to house an experimental synthetic aperture radar (SAR) to provide high-resolution ground mapping images, a capability similar to American E-8 J-STARS which also serves as an airborne C3I center. Besides the SAR radar, the aircraft still retains some original ECM and ELINT equipment, as indicated by the semi-spherical fairings and other small antennas under the rear fuselage. It was reported that China is expanding her Tu-154M/D reconnaissance/ELINT/ECM aircraft fleet with Russian assistance. So far there are at least 6 of these modified Tu-154M/Ds which first entered the service with PLAAF in 1995.

数架Tu-154M/Ds（I,II,III型）飞机已被解放军空军改装成电子战机，在中国民航注册以掩饰身份。III型机是由I型电子情报收集机发展而来，在机舱下方有一个吊舱，内部安装一台合成孔径雷达，可以获取高清晰度的地面图像。其性能与美国E-8联合星相似，但后者还可作为空中指挥机使用。除了SAR合成孔径雷达，该机同时保留了原有的电子对抗和电子情报设施，这从其后机身的各种天线可以分析出来。有消息称中国正在俄国的帮助下扩大其Tu-154M/D侦察/电子对抗/情报收集机群，自1995年起到目前，已有至少六架改装过的Tu-154M/D机加入解放军空军服役。[em09][em08]
