J-35 carrier fighter (PLAN) thread

[Confusionism]

Liaoning (Type 001) Capacity: Approximately 24 J-15 fighter jets
Shandong (Type 002) Capacity: Approximately 36 J-15 fighter jets

Maths:
J-15occupies 21.2 m × 14.7 m ~312 m²
J‑35 occupies 17.3 m × 7.8 m ~136 m²

Theoratically you could replace1 x J-15 with 2 x J-35
As a PLAN officier, it's a privileged "Battleship Boardgame" scenario to pick and choose from between how many J-35s vs. J-15s.

These figures are incorrect. The number of jets on the Shandong and Liaoning should be the same (with a difference of no more than one J-15), and the claim that the hangar was expanded by removing P-700 missile launchers has long been debunked.

The J-15/Su-33 has a wingspan of 14.7m, when folded is 7.4m, whereas the J-35’s folded wingspan is wider, around 8.8m.

You can see this difference quite clearly by yourself.

Most importantly, however, the number of fixed-wing aircraft carried by an aircraft carrier cannot be assessed based on the size of the aircraft. Because a carrier is not simply an aircraft transport ship; you must also consider the movement and placement of jets within the hangar and on the flight deck. Even if there are only a few J-15s, you still need to account for the space required for their movement.

As others have said, your numbers and your source are fundamentally incorrect, and your inability to judge them really casts doubt on what you've written overall.

There is a reason why I wrote "we don't know" to the question being asked.

Even if we knew what the specific footprint of a J-35 is compared to J-15, that actually doesn't tell us how many J-35s would fit in the place of J-15s, because it isn't just a matter of calculating surface area footprint directly, but rather it's a matter of how the specific geometry of one fighter fits versus the geometry of another type, in context of the overall flight deck and hangar work flow.

It isn't even only just a matter of aircraft footprint+geometry either -- wheel turning (and thus aircraft turn radius), spotting positions, maintenance spots, maintenance/support availability, etc... they all factor in.

And all of that is stuff which is basically impossible for us in the public space to determine -- even for the PLAN themselves they are probably going to have to do some rather thorough simulations and some practical demonstrations to figure out what the true optimal ratio is.

Hello dears,
I did make a mistake, but I shall come to it in a while.

your inability to judge them really casts doubt on what you've written overall.

I tried making an estimated guess. Yes there are "x" number of additional viarables when considering the possible numbers of J-35s a type 001/002 could carry. And doubts are good when they animate to re-imagine. I hope your doubts help you further.

Now to my mistake part:

J-35’s folded wingspan is wider, around 8.8m

I got the wrong folded wingspand of 7.8m from following "source":

J-15/Su-33 has a wingspan of 14.7m

The Wingspan for J-15 was misinterpreted due to orignal text-format and without any excuse I consider it as an actual big MISTAKE:

@Confusionism thank you for hitting the nail on the head without throwing tantrums

@GTI @Deino I appologize for creating a misconception.

Now back to the revised calculation (a rough top down area cross-section):

Revised Conclusions IMO: The space savings from replacing J-15s with J-35s are modest. Hence not a dramatic reduction in parking footprint.

Aircraft	Length	Folded Wingspan	Area (L × W)
J-15	21.2 m	7.4 m	156.88 m²
J-35	17.3 m	8.8 m	152.24 m²

The data inaccuracies are just the first part of what I’m saying, but my most important point is that you can’t infer a carrier’s capacity based solely on the approximate area of its aircraft. Since J-15 is based on Su-27—which wasn’t designed from the ground up for carrier operations—they likely waste a lot of space on the deck. Therefore, it wouldn’t be surprising if the carrier could accommodate significantly more J-35s. Therefore, it is very difficult to estimate the exact replacement ratio between the J-15 and the J-35 based on currently available public data. It would be better to simply admit, as Blitzo did, that “we don’t know.”
I can also understand others’ frustration, because this subject has been thoroughly discussed in multiple threads, and you clearly did not carefully review them before answering—let alone citing data from Baidu Baike...

I just wanna see the J-35 overhanging beyond the deck edge.. Such a small detail

Could you please tell us on what dimensions you base this IMO strange calculation?
Give the source's rather limited credibility I have some very strong reservations on that data.

Probably based on his experience in WarThunder.
