Oh come on ... just again posting only for the post's sake!
Not again Deino, what is the issue with you dear?
You may be the most knowledgeable poster on Chinese hardware in the World but you are certainly not an employee in Shenyang. Do you even know how many Pakistani Engineers have been seconded by various Chinese aircraft manufacturers including Chengdu, Nanchang, and Shenyang over the years?
The answer is a big
NO because all these matters are between Govt to Govt. I say that because one of my cousins served there, who retired as an Air Commodore in the PAF. Pakistanis along with others have been giving their input for decades, the Chinese are grateful for their modernization efforts.
When the top men in the PAF declare the induction and training of the J31, it does not mean they are receiving the jets in the next decade. It means they have sorted out all the modalities and are ready to receive the production models.
It may sound like a surprise to you but this is how our procurements work. We waited for India to waste its resources on Rafale and in the meantime worked on the J31 procurement. Had we declared it earlier the Indians would have gone on the Stealth aircraft procurement rampage all over the World. An insight into our F16 procurement and the Indian
NIGHTMARE spanning over five decades will be helpful.
So sir we value your precious input but please don't act as a spoiler in our happiness, it is below your stature. And certainly, if the Jets don't arrive within the next 18-24 months, we will apologize and hope you do the same if it happens.
