The Chinese working on something and having command over womething are 2 different things. If you talk qbout the 90s they had a major accident on the J0 in 96 causing them to redesign the whole thing. So respectfully I will disagee with you here.
Whatever the specific design considerations of the J-10, but in the 1990s, the Chinese were comfortable enough with tackling a relaxed stability design and building its entire flight control system. You need capacity to do it before starting it, otherwise, you take the PAF route of asking someone else to do it.
These are the key ingredients of a 4+ gen fighter. Frankly, the fact that the Chinese were undertaking such a project gave the PAF a leg-up over the IAF, which had to deal with developing the Tejas' FCS alone very early on. We at least had a large power to collaborate with on this front, and we didn't take leverage it.
However, we do know (and it's on the public record since the Sabre II days) that the Chinese were open to collaborating with us on a fighter. They were venturing into original design, so this idea that we had zero chance of taking them up on something more complex doesn't fly. When you start fresh, having partners to share costs and risk is generally desirable.
Going for J10 had complications associated with it. Firstly how do you know whether the Chinese would actually want you to have access to their tier 1 platform. Secondly given the problems mentioned above I think the project was deemed risky and rightly so. Lastly we would have just kit assembled the platform as the capacity to adopt the platform was not there. Lastly the engine was Russian and in use by IAF. I dont know whether the Russians would have allowed PAF access to it. Lastly the cost of the platform would have been much higher so numbers would have suffered
Well, the earlier one joins in sharing the cost and risk, the more leverage one can get. When the J-10 was a new, ambitious and high-risk project, the door for the PAF was at its widest. As the Chinese matured along the J-10 (and started new fighter programs, like the J-20 and FC-31), that door narrowed and closed (i.e., we can only be customers now, not partners). We are now facing the same question with Turkey; do we want to join when it's high-risk, high-reward?
As for the workshare details. The point isn't to worry about final assembly, but to enter the supply chain of the fighter. Even if we didn't assemble the fighter, if we got a 1/3, 1/4 or even 1/5 workshare deal, then the likes of PAC would actually manufacture and send components back to China. That results in an offset, i.e., partly paying for some of the program back to our economy.
The second component was the opportunity to learn about the technology, including transfer of IP (which we could have co-funded). In turn, these are the parts that would've helped us in our next step, i.e., either design our NGFA as independently as possible, or be a very valuable partner.
Basically, everything doesn't need to boil down to final assembly or production, but rather, whether your industry is growing organically (via 1st, 2nd and 3rd party sales) and your tech base is expanding.
As for the Russian engines. Moscow literally had every opportunity to block the transfer of RD-93s and delay the JF-17 by a decade. If there was a way to get the RD-93, there was probably a way to secure the sale of the AL-31. In fact, in the 1990s, we even tried getting cheeky with the Russians by leading them on about the Su-27 so that we could get a better deal for the M2K (see Flight International 1994-1996).
Now the J-10 aside, the PAF asking for more design features in the Super-7 doesn't automatically mean a J-10 competitor. The two are still in different leagues from a range and payload standpoint. If the PLAAF was focused on the latter two, then it wouldn't even care for a 1:1 Gripen. As far as the Chinese would imagine, the PAF asked for specific features for its specific needs, it will get them. If anything, the funding the PAF puts into the R&D for those inputs would make their way to other Chinese programs. So it's a win-win.
Whether the Chinese (a) had the capabilty to design and build a fighter as sophisticated as the Gripen or (b) had the will to do so thereby creating a direct competitor to the J10 can be debated. I think the answer to both would be negative.
PAF evaluated the Gripen and the alresponse from the horse's mouth was "the plane is too sophisticated for us to absorb the technology". This is opensource information. So we could possibly not have absorbed the J10 either in the time frame we are discussing.
You need to qualify "too sophisticated for us to absorb the technology" with the details.
The PAF understood how to absorb the airframe -- a relaxed stability design with FBW similar to the F-16 -- but not the full extent of the radar, avionics and data-link stack. That was new, but even then the PAF had understood how it worked (as it requested the F/A-18 along with the F-16 in the early 1980s, see WikiLeaks).
In fact, the PAF called for a Gripen-like electronics stack in the JF-17 (e.g., similar MFD HMI, TDL, HMD/S, etc). However, the PAF couldn't do a lot about the airframe design as the JF-17 was beyond the point of fundamental changes. The designers did try to alleviate some of the issues via the Block-III, but it won't fully compensate for the inherent design limitations of the fighter.
Agqin when the technology is lacking at the source how does one inch towards it. Shahid Lateef has openly stated we found 30 things we wanted to change on the J10. I dont think the Chinese on their own would have been able to do so and neither could we have.
This is actually good. So we identified gaps in the J-10. We could've withheld that information in return for a seat at the J-10 program. This was leverage we could've built upon. If we had bought into that fighter, we could've both asked for more and, in return, helped the Chinese understand more.
Remember it was not till 2013-16 that our interest in the J10 was rekindled. Its engine remained a big hurdle as the PAF did not relook the project till the Chinese had incorporated the WS10 on it.
But our initial interest in the J-10 dated back to 2004-2005 with the "Plus One" program. In fact, the PAF's AFFDP-2015 had even budgeted funds for the FC-20 (i.e., J-10A) in 2006-2007.
So at that time, the engine was not an issue, neither were the electronics, weapons, etc.
It's curious we could summon the funds for 36-40 FC-20As, but couldn't invest more in the JF-17 to make our fleet-builder as good as possible. FC-20 got canned due to the issues of the late 2000s/early 2010s.
This is the issue I've been bringing up in this thread. How is the JF-17 beset with budgetary constraints, yet some off-the-shelf solution isn't? In fact, this is still the case as the PAF is looking at the J-10CE while it will only commit to an order of 30 single-seat Block-IIIs!
Going for a fighter like the Gripen would have involved a deep pocket which the PAF did not have, time which again it did not have, and ability whivh I sefiously doubt was there. We have had to incorporate Western tech in so many areas to achieve our aims. Even the parameters for the radar were provided to the Chinese and then reluctantly obliged to for fear of losing business.
The PAF incorporated Western (or original design tech) in the RWR and some subcomponents of the HMI (as confirmed by Usman Shabbir on PakDef). Except for the RD-93, the JF-17 is Chinese in every other area where it matters. We are now at the point where our new technologies (e.g., AESA) are coming because of Chinese advancements in those areas. We didn't fully appreciate the depth of the Chinese industry in the early days, so we didn't get a stake nor did we properly learn. We're still not learning the lesson.
As to the Gripen @Madam messiach and
@bilal khan777 have both said the fighter is over rated and the JFT capability wise is very much there.
The point was never "we should've chosen Gripen over JF-17," rather, "we should've taken on more of the technology of the Gripen into the JF-17." Two very different points. Ask the PAF if they could have a more maneuverable asset with a higher payload, they'll say yes.
As to the Tejas they bit off more than they could chew. From the management perspective it is a classical example of how not to do/it. I dont know which industry you refer to but their Mk 2 whatever would be lucky to see the light of day this side of 2030.
The Tejas Mk2 has the specifications and features of a Gripen E/F. The fact that they have a timeline (2030) is actually more than what we can say about a comparable JF-17. The Block-III has a comparable tech stack Tejas Mk1A (minus HMD/S, which we don't have yet), but otherwise, no major feature differences. But the PAF has no plans for an enlarged JF-17 akin to what the Tejas Mk2 is to the Mk1A, hence all the buzz about the J-10CE. So, while the Indians have had their project management issues, they're moving to evolve their aircraft program -- and are on the verge of starting the TEDBF/ORCA and AMCA -- while we're vague about our commitment to the JF-17 Block-III (i.e., only signed for 30 out of the 50 planes we were planning for).
I would be surprised if they managed to turn that Samosa around. I suspect we will progress on to mk3 as the next Mk wilp become obsolete by the time they come round to inducting it. And they wilp keep buying from foreign providers and keep getting bad outcomes as systems will npt talk to each other. Frankly i would not want to be in their shoes.
I urge you to read up on the Tejas in more detail. Sure, the fighter itself might not be up your alley, but the flight control tech, gas turbine research, electronics stack, industry base, etc are all leagues ahead of where the PAF is at. You can ask the engineers on this forum, especially those with exposure to PAC and AvRID.
What are the chances that after the initial import, further acquisitions of the J-10s could be assembled in Pakistan like the Raptor of the East (Bingo)?
Also, let's say Pakistan replaces all F-7s and Mirages with Made in Pakistan JF-17 Thunders and replaces all F-16s with mainly Assembled in Pakistan J-10s and works on the NGFA at simultaneously, would that feasible?
In other words, 2 active platforms and 1 in design/construction phase through 2020s and 2030s.
Assembly = Importing with More Steps.
So, no.
We need indigenization of the inputs, be it at the material sourcing level, or value-added manufacturing level.
This requires a healthy and consistent run of R&D and IP development, something we should've started with the JF-17 (ideally earlier). Basically, we move to design, develop and manufacture the critical inputs, and, in turn, give Pakistanis both jobs and high value exports.
