China has inducted J-20 and probably will not go towards J-31. This will create delays in the development of J-31 and probably it will be ready for production by 2027+. M/s Shenyang Aircraft Corporation may need some financial partner for early development of J-31. However TFX program will be on...
Chinese radars (JYL-1 Long-range 3D Air Defence Radar, YLC-2A/2V 3D phased array radar) are equally good. Chinese latest JY-26 Phased Array Radar can detect stealth aircrafts.
Problem of the JF--17 engine will solve after the induction of any fighter, either Su35 or Ef2000. However quality of western avionics and engine would be better for future JF-17 blocks. Similarly Middle East countries have already switched to Ef2000 and Rafale.
Is it possible to integrate weapons on T129 as per placement made in AH-1Z? (i.e rockets on the corner downside and Air-air missiles on upper corner tips). This will create more space between weapons.
I think Pakistan should work with Aselsan for a possible quality solution of various critical items for its JF-17s like AESA radar, HMDS, superior avionics, jamming pods etc
Aselsan of Turkey is working to develop a similar system to the French TopOwl Helmet, called the AVCI Helmet Integrated Cueing System. The system can also be further modified & utilized in JFT block-3.
Best strategy is to get both options Chinese (for export purposes) and Italian (self). Italian AESA with swashplate solution will also bring Skyward-G infrared search and track (IRST), and BriteCloud digital radio frequency memory (DRFM)-based ECM system.
Apart from Agosta-90b, Agosta-70 should also be upgraded from Turkey (command & control, electronic support-attack system, communication systems) & Sweden (AIP, Torpedo 2000)
Disadvantages of J-10:-
1) Short ferry range wrt weapons load
2) Engine problems (failures etc)
However these problems will be solved with the advent of J-10D with CFT and WS-10G engines.
Advantages of J-10:-
1) AESA radar of 1200 T/R Modules (better range than 1000 T/R of JFT block-3 and...
100 million US$ will be for upgrade services, while AESA radar and other associated equipment should be procured from USA through FMS (From the F-16 money).
