I still pessimistic so let's see in the future.Plus this war isn't helping that cause, either. The way I look at it is they currently have 4 completed production models, aside from the 10 prototypes. The VVS I think has ordered 78, or something like that? So if the war wraps up in the next couple of months and they get back on track, they can have half that number of aircraft built for the VVS by 2025. By then the EAF should have their F-15s arriving around the same time, then they can negotiate a contract for the Su-75 to commence as soon as they finish the VVS' order which should be around 2027 or so. Then the EAF starts receiving them around 2030 give or take.
Otherwise, what is the other option? J-20 is not for export. China has already claimed that if I'm not mistaken. Besides, that aircraft is really designed for a massive territory just like China because it carries A LOT of fuel. It might not be the practical choice for the EAF anyway. Not sure where the J-31 is at. That might be right along the same process as the Checkmate.
The Checkmate won't go into production until 2027.
Now if this aircraft is not being built for the VVS and is strictly for export contracts like they claimed it would be at the unveiling, then this might be the better option as far as timing is concerned. However, that might not be so smooth with all the required testing time that would be needed before they can produce contracted platforms. So realistically, that's also the soonest would be 2030 for that platform. The Su-57 is already tested and just needs to be produced with the finalized items taken care of.
I think China have put J-31for export and they are willing maybe in the future to export J-20. Coincidentally, the Interior Minister of Pakistan was the one who announced the purchase of J-10C and they bought it and few months (March 2022 I think) he said that Pakistan will likely to acquire J-20. So if he confirms that means that the J-20 is or will on the market in the upcoming months or years.
After J-10, Pakistan To Get J-20 Stealth Fighters From China As Top Minister Calls Them ‘The Most Modern Aircraft’?
Pakistan has started to procure J-10C fighters jets from China, as the EurAsian Times previously reported. Sheikh Rasheed Ahmad, Pakistan’s interior minister, was the first official to announce the procurement last December when he said the newly-acquired jets would conduct a fly-past during the...
