At least two Boeing 737-300s belonging to the PLA Air Force 34th Air Division (VIP transport division) have been converted into airborne command posts carrying special command, control, and communications equipment. The plane features a large fairing containing electronic equipment (satellite communications?) located on the top of the fuselage behind the cockpit. Two more fairings are located underneath the mid-section of the fuselage, which could house secure datalink and/or ECM antennas. The aircraft also adopts a light grey air force colour scheme.
