R-37M to India even if non-downgraded and featuring Russia's full range, is still something IAF can't make use of anyway.
The Rafale is not compatible with the R-37M and cannot be made so without source codes and even with source codes would typically take many years to decade of dedicated effort as is the case with almost all weapons compatibility programs from PL-12 on Su-27SK (J-11A) to Meteor on Gripen to Brahmos NG on Su-30MKI.
R-37M outranges the available capacity of Su-30MKI's Bars radar. Bars radar is absolutely useless for frontline standard. It was good in the 1990s era (even though it came in the early 2000s), already poor performance by 2010s and now useless. It's a good pair for R-77 even at a stretch make use of R-77M generation but for R-37M? lol
PAF should still only be concerned about S-400, Rafale and Meteor. Just laugh at the idea of R-37M. Unless India buys Su-57, the R-37M can be dismissed. S-400, Rafale and Meteor are still capable systems and require very capable ISR, planning and PAF execution of air combat for success like in May 2025.
PL-17 is not for export yet. PLAAF has longer ranged AA missiles than PL-17 already. This has long been hinted by very credible sources who have not been wrong or led us astray. In fact they all say there are more than one missile in PLAAF testing or even use that outranges PL-17. Main weapons bay for J-36 isn't designed around PL-17 which is a 10 year old missile already and designed in the 2000s era.
Therefore I think PL-17 for export isn't out of the question for short or medium term future. Once PLAAF have newer ultra long range AA missiles in active service and in mass production, PL-17 probably will get an E version. No reason why it cannot be carried by J-10CE since the load and drag is still lower than many A2G munitions the J-10CE can carry on the centre pylon. The YJ-91 anti radiation missile which is developed from Kh-31 is heavier and draggier than PL-17.
You could have a pair of J-10CE with the following air to air configuration.
First fighter:
2x fuel tanks
2x PL-17
2x fuselage mounted PL-15
2x PL-10 or even forgo these for BVR only to save weight and drag
Second fighter:
2x fuel tanks
4x wing mounted PL-15
2x fuselage mounted PL-15
2x PL-10 optional
The weight and drag penalty of this A2A loadout isn't going to penalise the WS-10B powered J-10CE all that much to be honest. Like yes it's semi-beast mode because this is maxing out it's A2A capability but US corporations advertise stupid weight and drag level beast modes with a thrust:weight+drag penalty ratio that is more absurd which means this loadout is doable.
Rafale pilot spoke about carrying 2x Meteors to A2A fight is typical to improve energy performance and management but Rafale can also double that and carry a few Micas or Magics along with and at least 2x fuel tanks.
Anyway that's realistically taking to a fight with just two J-10CEs up to 2x PL-17s and 8x PL-15s with enough fuel for longer range and dwell time.
