It’s a good jet and I hope they target enemy airbase next time. I think training related to ground attack should be given as priority. This is one feature that was missing. Air to air is all good, air to ground attack needs attention.
Modern fighter jets have many functional subdivisions. Often, the air forces of large countries will have different fighters with different functions, and they form a large formation of fighters that work in concert with each other.
Smaller air forces, on the other hand, usually have trouble affording such a large expenditure, and they favor multi-mission fighters.
For example: the IAF's Rafale is a typical multi-mission fighter. In fact, most of the European countries prefer multi-mission fighters.
The same is true for the PAF; the J-10C was originally an air superiority fighter, but its foreign trade version (PAF version) became a multi-mission fighter. I personally don't agree with this choice of PAF. I think PAF should have opted for a purely air superiority version of the J-10CE.
Being able to do everything also means not being able to do anything best.
However, PAF has opted for a multi-mission version of the J-10CE. Well, when PAF is procuring the J-35, I hope they go for the pure air superiority version to form a combination with the multi-mission version of the J-10CE.
For Pakistan, J-35A acquisition will present several challenges.
Even if China provide at reduced costs, lifetime support, maintenance, spares, costs will be more than the planes itself.
Repair, and maintenance for stealth will be additionally difficult.
Fixing Composites, Airframe skin, RAM, will be costly unless Pak builds a separate infrastructure for repair and maintenance, which will be challenging in the absence of domestic mature know how.
All 5G fighters are very expensive to maintain. It's a price that has to be paid.
China can do it:
Same class of fighters, we have the lowest price.
Same price fighter, we have the best performance.
This is while China has not finalized the engines, and still developing WS19 or any Western comparable engine.
May be just replace engine every 3000-4000 hrs!
How can an unproven, unmature turbojet can be installed in a 5th Gen Fighter?
The two threads on J-35 in the PDF are very detailed and accurate. I suggest you go back and read about it before making a judgment.
