context_page_description: This is a list of variants and specifications for variants of the Chengdu J-7, which differed considerably between models in its 48 years of production run.
context_section_description: After nearly a decade long hiatus on the internal military aircraft market in the 1990s, China attempts to return by marketing the F-7MG series fighters based on the J-7E series. As with earlier J/F-7M series, in order to speed up the development, it was decided to first develop different prototypes each with a different tasks of trials.
  J-7MG avionics testbed: A single J-7M with serial number 0143 was converted for testing avionics of J-7MG. Avionics tested included Type KTR-908 and 909 radios, Type KNR-634A navigation system, Type KTU-709 TACAN, Type KDF-806 compass, Instrument landing system (ILS). This J-7MG avionics testbed is the only model of J/F-7MG series without the double delta wing. Initially, the program was not funded by the Chinese government, so the 30 million ¥ needed was jointly funded by CAC, Guizhou Liyang Aeroengine Co., Ltd. and China National Aero-Technology Import & Export Corporation (CATIC) using companies' own money.
  J-7MG: prototypes of F-7MG, with avionics tested on J-7MG avionics testbed and double delta wings of J-7E. A total of 2 were built, with serial numbers 0142 and 0144. British GEC-Marconi that provided avionics for earlier J/F-7M once again was selected to provide airborne radar for the J-7MG series, and this time the British firm provided Super Sky Ranger (SSR) radar with planar slotted array antenna capable of scanning ±30°, and it is an upgraded version of earlier Sky Ranger / Sky Ranger 7M ranging radars with parabolic antenna used on J/F-7M. SSR can be hooked up wither by ARINC 429 or MIL-STD-1553 data buses, and it provides both air-to-air and air-to-ground ranging.
  F-7MG: Development of J-7MG, with a single piece windscreen replaced the 3-piece of J-7MG. Evolved to F-7BG.
  F-7BG:  F-7MG for Bangladesh with both the wing reconnaissance pod carrying capability and capability to carry aerial drone under the fuselage of earlier F-7MB retained. 12 delivered in 2006. F-BG would later be upgraded with Italian Grifo-Mk-II radar.
  F-7NM: F-7MG derivative for Namibia, 6 delivered in 2005.W/ domestic Chinese fire control radar either SY-80 series by (中航工业雷达与电视设备研究院) or KLJ-6E fire control radar by the 14th research institute, but the exactly which one of the two is not confirmed by China. Both fire control radars have almost identical performance, such as both have a range of around 30 km and weights around 60 kg. China decided to have both radars entering series production and distribute them among different orders of F-7s. If F-7NM is equipped with SY-80A series radar, then F-7NI would be equipped with KLJ-6E, and conversely, if F-7NM is equipped with KLJ-6E radar, then F-7NI would be equipped with SY-80A series radar.
  F-7NI: F-7MG derivative for Nigeria with 12 delivered. Chinese sources have confirmed that F-7NI differs from F-7NM only in avionics, but has failed to identify exactly which fire control radar is used on which model, thus if the former is equipped with SY-80A series radar, the later would be equipped with KLJ-6E radar, and conversely, if the former is equipped with KLJ-6E radar, the latter would be equipped with SY-80A series radar. Practice of concurrent production of two different radars with nearly identical performance is to keep both production lines running so that different vendors' known how would not be lost.
