J-35 carrier fighter (PLAN) thread

Production capacity is unlikely to be a primary factor, since as pointed out, they could expand CAC or even subcontract/work share with SAC.

It would take considerably less time and expense to expand production capabilities than finishing off the J31 design AND also set up a seperate production line for that also.

What might be a more significant and hard to bridge capacity gap might be in terms of the design team.

From various comments on the J20 from officials and members of CAC, we know that the PLAAF and CAC have a lot of long term plans to continue to develop the J20. Potentially with new variants, purhaps along the lines of the aborted FB22 where a more dedicated strike variant is developed.

In addition, the PLAAF is likely to keep CAC busy for years to come as they learn more about the J20’s capabilities and limitations and wish list changes and modifications. Not to mention the upcoming WS15 integration work.

But OTOH, designing a carrier capable J20 will also be a significant undertaking that will require potentially years of the J20’s design teams time.

As talented and as capable as CAC and the J20 design team are, I would seriously doubt they could take on both those fronts at the same time.

It could well be that there is a bit of a turf war going on behind the scenes between the PLAAF and PLAN, with neither service prepared to have their needs come second place.

The PLAAF has first dibs on CAC’s time by dint of already having the J20 as their official backbone project. So rather than potentially having to wait years before CAC even starts serious work designing a carrier J20, the navy could have decided to go with the J31.

There would have also probably been significant political support for the navy choosing SAC as a means of maintaining a real competitor to CAC to keep their on their toes.

That political support may well come with additional funding and/or pull to get CAC to share key J20 tech with SAC to help ensure the J31 is technologically competitive with the J20.

Hopefully loosing the PLAAF to CAC has served as a much needed wake up call for SAC, and they can make the most of every advantage offered and this lifeline and up there game significantly. Because I think this is probably their last big chance.

If they screw up with the J31 naval contract, China would be better off building up one of the other main aviation firms up as an alternative fighter maker to CAC and let SAC die.

I thought the FC-31 design had already "won" (if there ever was a competition in the first place) if we go by what "PB" and other insiders have recently said.
Also, engine and materials technology are tied to both the FC-31 and J-20 programs, not just one of them.

That doesn't make sense, though, since the FC-31 was never part of the original J-XX competition. It was between the J-20 and a tri-plane design from SAC.

A selected translation:


The mean assumption of this is that FC-31 can achieve similar engine performance to or at least catch on with that of F-35. If we assume that F-35 and FC-31 have similar electric capability and similar support from other units, his comment sounds reasonable. However, how much of the assumptions reflect reality should be another discussion on its own right.
Doing exactly the same thing as a competitor on lower technical level, later, while knowing more or less what competition intends to do.
Author of this quote makes it sound like a diversion.

I imagine if an FC-31 variant were chosen the production line for the J-15 would be converted over. They wouldn’t necessarily need to build new lines, or, rather, waiting on new lines wouldn’t prevent them from starting production, as it might with CAC. I also imagine that sorting out the details for contracting out production from one firm to another would take more time and be more of a headache than simply letting firms deal with their own production in-house.

It’s also not like if the J-20 were selected it wouldn’t need development time either. SAC going it alone on FC-31 development pretty much leveled that consideration. Development time and cost wise a J-20 variant and an FC-31 variant would probably be about the same. If anything, if a J-20 variant were required to be downsized to use a mid thrust engine CAC’s offerings may require more development time. Meanwhile, in terms of production capacity CAC would have to find a way to expand their lines one way or another, while SAC would simply have to convert theirs over. Even CAC contracting SAC’s capacity isn’t exactly a trivial exercise. Coordinating with an external team to run production requires more juggling than simply going to your own.

A lot of people are asking, why do you choose 31? I think there are two problems with which we are "entangled". First, this is not 20 or 31 of the problem, the carrier is a medium machine, I mentioned that the Sea 4 has been said "medium machine" the word to replace. I don't know 20 how to change or 31 how to change, anyway who changed to who on. The hangar is so big that the body is smaller and more loaded. Second, how do you know that 31 on the line or not, although the urgent (specifically do not pull the hidden change of the matter), but as long as the final can not reach the Navy to mention the same as the indicators, the opposite is OK.
