Discussion continued here to avoid derailing the original thread.
Such discussions often return to the similar types of arguments regarding the need to procure J-35As, especially with the relatively young fleet of the 4.5th-gen fighter (J-16) fleets available to the PLAAF and the incoming 6th-gen warplanes (J-36 + J-XDS) in mind.
Some factors to consider:
#1: Same as the debate for retaining J-16s (if not also J-10Cs, let alone J-11BGs) versus procuring large numbers of J-35A for the case of the PLAAF:
- Can 5th-gen fighters do everything that 4.5th-gen fighters do? Absolutely.
- Can 4.5th-gen fighters do everything that 5th-gen fighters do? Absolutely not.
The same also applies to the J-15T versus the J-35 for the case of the PLAN.
#2: Sure, the limited number of parking slots on PLAN CVs certainly is a significant factor for the PLAN to consider which carrier-based fighters (and how many of each model) could be deployed onboard.
However, this is also similar (in a sense, at least) to the resources, budgetary, and manpower constraints faced by the PLAAF (albeit dialed to a higher number for the PLAN). Also, take #1 in mind.
#3: Of course, the J-15 has a greater payload capacity (in terms of number of weapon pylons) than the J-35 (similar to how the J-16 has a larger payload capacity than the J-20+ J-35A). However, nobody said that the J-35 couldn't carry YJ-15s (of which
one academic paper seems to indicate this to be the case).
In addition, the J-35 is able to carry munitions inside its IWB and maintain an LO profile, which is something that the J-15T will never be able to do. And once again, refer back to #1.
#4: Yes, the carrier-based J-XDS (let's call it J-XDSH for the sake of this discussion) will be better and superior than the J-35 in a lot of ways. However, at this stage (if not for quite some time going forward), we have no confirmation that the J-XDSH is in a similar stage of development progress as the J-36 and (the land-based variant of) the J-XDS right now.
Hell, are we even sure that the J-XDS will have a carrier-based variant developed for the PLAN CVs (i.e. J-XDSH), instead of a completely separate, clean-sheet carrier-based 6th-gen fighter design (J-XDH) to begin with?
#5: Continuing from #4 - Could we even guarantee that there won't be unforeseen delays or hiccups to the development of the J-XDSH (or some other clean-sheet design (J-XDH)) that would negatively impact the timelines of when they can be deployed on PLAN CVs? The rather tumultuous development of the WS-10H/H2 alone is a primary example of this.
With this in mind, procuring a large number of J-35s certainly makes a lot of sense to serve as a useful hedge against such uncertainties and potential deficiencies, especially when considering the increasingly turbulent geopolitical and geosecurity developments in the WestPac and around the world.
