caption_attribution_description: Sri Lanka Air Force Chengdu F-7GS Interceptor Aircraft, export version of the Chinese Chengdu J-7.
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: J/F-7G series is the further development of earlier J-7E series. Contrary to many frequent but erroneous claims, the fire control radar is not the Chinese development of EL/M-2001B radar, because EL/M-2001B is a pulse Doppler ranging only radar. Instead, the Chinese fire control radar for J-G is developed from EL/M-2032 fire control radar China obtained from Israel when it was a subcontractor for Elbit in the Romanian MiG-21 LanceR program described above.
  J-7G: Upgraded J-7E with more than 30 improvements with Mr. Song Cheng-Zhi (宋承志) as the general designer. Equipped HOTAS and a Chinese derivative of EL/M-2032. However, due to the inherit limitation of the small size of the nosecone, the antenna size of EL/M-2032 has to be greatly reduced, resulting in the drastic decrease of the original 150 km range of EL/M-2032 by approximately 60% to slightly more than 60 km. Development begun in March 2002 and completed in July 2004, with delivery begun in Nov 2004.
  J-7GB: J-7G derivative for August 1 aerobatic team. Replacement for J-7EB begun in 2004
  F-7TN: Cheaper version of J-7G for Tanzania with KLJ-6E fire control radar with 30 km range.
  F-7GS: Modified version of J-7G for Sri Lanka with other avionics specifically to meet requirements of Sri Lanka, and these modifications include:
  A new head-up display (HUD) with a new Stores Management System, which is essentially a useful cockpit-pilot interface to help establish the status of stores including configuration, fusing and weapon codes etc. A voice warning system, color video recorder, elaborate cockpit lighting (Night Vision Goggle Compatible) and a more precise and jitter free AOA probe, GPS and inertial navigation system (INS). GMAv AD 3400 UHF/VHF multifunction com, Type 605A (`Odd Rods` type) IFF, KLJ-6E pulse Doppler radar with a range of 30 km. WL-7 radio compass, 0101 HR A2 altitude radio altimeter, LTC-2 horizon gyro, XS-6 marker beacon receiver, VOR, Distance Measure Equipment (DME), Instrument Landing System (ILS), tactical aircraft navigation (TACAN) system and an improved Type 8430 air data computer with HOTAS.
  The new HUD developed by  Norinco subsidiary North Electro-optic Co., Ltd. (北方光电股份有限公司) provides pilot with displays for instrument flying, with air-to-air and air-to-ground weapon aiming symbols integrated with flight-instrument symbology. It can store 32 weapon parameter functions, allowing for both current and future weapon variants. In air-to-air combat its four modes (missiles, conventional gunnery, snap shoot gunnery, dogfight) and standby aiming reticule allow for all eventualities. VCR and infrared cockpit lighting on the F-7GS is to be used with a Chinese (Cigong Group) Helmet Mounted Sight (HMS) slaved to the PL-9 AAM. The new air data computer coupled with the new HUD in the air-to-ground mode is capable of projecting both Constantly Computed Impact Points (CCIP) and Constantly Computed Release Points (CCRP).
