The Pakistan Aeronautical Complex (PAC) will start producing an upgraded version of its with China co-developed JF-17 Thunder fighter-bomber. The announcement was made at the aircraft manufacturing plant in Kamra, where the PAC formally handed over the 50th JF-17 Thunder aircraft to Pakistan Air Force.
Exactly what will be new on the JF-17 Block II Thunder is somewhat vague, but they include partly new avionics, additional weapon options and an air-to-air refueling function.
Pakistan has plans for a total of 250 JF-17s, that will take over the fighter-bomber roles of old Mirage III, Mirage V and F-7s.
