Re: Chengdu J-7
'F-7P’ Newly built Skybolt for the Pakistani Air Force (PAF).
A total of 60 were built. Starting with this model, F-7s in the Pakistani service began to be upgraded with the Italian FIAR Grifo-Mk-II radar license assembled by the ISO - 9002 certified Kamra avionics, Electronics and Radar Factory of the Pakistan Aeronautical Complex (PAC).
In comparison to the Grifo-7, the new radar only weighs an extra 1 kg (56 kg total), but the sector of scan was increased to ±20 degrees from the original ±10 degrees of Grifo-7.
The newer radar also had improved ECM and look-down and shoot-down capability, and can track 4 targets simultaneously while engage one of four target tracked.

F-7PG Export variant of the J-7PG, with the single piece windshield replacing the 3-piece windshield of the J-7PG.
Pakistan ordered a total of 80 in two batches, with 50 and 30 respectively in each. According to the Pakistan Air Force, the performance at high altitude of the F-7PG has increased more than 83% in comparison to the F-7P/MP.
Just like the earlier Italian FIAR Grifo-Mk-II radar on F-7MP/P, the Italian FIAR Grifo-MG radar of F-7PG will be assembled under license by the ISO - 9002 certified Kamra avionics, Electronics and Radar Factory of the Pakistan Aeronautical Complex (PAC).

Re: Chengdu J-7
Super-7 did away with British upgrades to the F-7M in the mid-1980s.
After a successful deal with Chinese in the early 1980s resulting in the F-7M, the United Kingdom offered a further upgrade to improve the performance of the F-7M by adopting either General Electric F404 or Pratt & Whitney PW 1120 turbofan engines.
The radar options would include the Red Fox, a repackaged version of the Blue Fox radar used on Sea Harrier FRS Mk 1, or the Emerson AN/APG-69.
Although radar tests were successful, the upgrade was rejected before any engine tests, because a single radar or a single engine had cost more than a new J-7 (2 million United States Dollars, 1984 price).
The name, Super-7, however, was retained to be used for the FC-1 / JF-17 light-weight fighter.

F-7S Saber II Replacement for the Super-7.
Re-designed F-7M by Grumman Corporation for the Pakistan Air Force. Side intakes replaced the nose intake and a General Electric AN/APG-67 radar on F-20 Tigershark would have been adopted.
The program was terminated due to the Tiananmen Square protest of 1989.

Re: Chengdu J-7
Bangladesh
The Bangladeshi Air Force, currently operates F-7MB Airguards, and F-7BG/Gs interceptors.
The F-7MBs will be replaced by 16 F-7BGI fighters by 2014. BAF has also upgraded all of its F-7MBs and F-7BGs to fire Chinese built LS-6 and LT-2 ground attack munitions, giving them a potent strike capability.
Pakistan
Pakistan is currently the largest non-Chinese F-7 operator, with ~120 F-7P and ~60 F-7PG.
The Pakistan Air Force is to replace its entire fleet of F-7 with the JF-17 multirole fighter, all F-7P are planned to be retired and replaced with JF-17 Thunder aircraft by 2015.
Sri Lanka
Sri Lanka Air Force used three F-7BS and for ground attack missions against the LTTE and three FT-7 trainer. Due to the lack of endurance and payload, SLAF some times uses their F-7s for pilot training purposes.
Early 2008 the air force received six more advanced F-7Gs, these will be primarily used as interceptors.
All The F-7G's, F-7BS's and FT-7s are flown by the No 5 Jet Squadron.
Sri Lankan officials reported that on 9 September 2008, three Sri Lankan Air Force F-7s were scrambled after two rebel flown Zlín-143 were detected by ground radar, two were sent to bomb two rebel airstrips at Mullaitivu and Kilinochchi areas, the government claims the third intercepting one ZLin-143 resulting in one LTTE Zlín-143 shot down by the chasing F-7G using air to air missiles while the rebel flown light aircraft was returning to its base at Mullaitivu after a bombing run against Vavuniya base.
There is no public evidence for shooting down LTTE flight.
