J-20 5th Gen Fighter Thread VIII

Ain't one of the main points of fifth Gen engines is to be more efficient? Am I missing something

The core tech stack is more efficient but how you employ your improved margins to optimize for different aspects of performance is a different matter.

There is always the tradeoff. You can either have higher speed/supercruise at the expense of lower maximum thrust (sea level) and range.

In the future, the J-20 is likely to evolve along two distinct technical paths or variants:

One variant, powered by the WS-10C2 engine, will prioritize cruising capability. It will offer extended range but slightly inferior high-speed performance.

The other variant, equipped with the WS-15 engine, will focus on burst power (raw thrust). It will excel in high-altitude, high-speed penetration, albeit with a shorter range.

Existing airframes will be gradually retrofitted with the WS-10C2, while newly manufactured units will primarily feature the WS-15. These two paths will run in parallel and evolve independently.

In 10 to 15 years, when Variable Cycle Engines (VCE) mature, we will see a combination of both advantages—though by then, we will likely be in the era of 6th-generation fighters.

This is really unnecessary when you can just lean on aerial refueling and drop tanks.

Without ws-15, comparison with good old f-22 was very much up in the air.
Raptor had huge combat energy state advantage, defensive and offensive. And, almost certainly, huge power advantage as well(engines designed to a spec). Yes, it is almost certainly not even nearly as networked as J-20; time matters(Motorola RAZR v3 v Huawei mate p30, hah). But it's networked enough between each other for of-ca.
Old radar, new radar - as long as it generates fire solution in time, prima facie it is inconsequential.

I.e. in pure air superiority contest, f-22 is likely still the top dog. It only starts falling below j-20(a) (likely) if we add mission complications where situation complexity outweighs this raw performance.
Which likely still makes J-20A ws-10c superior air superiority unit overall, but it's hard to judge. Performance is performance.

With WS-15 all these points are likely turning moot. Though unlikely to a degree where f-22 will turn uncompetitive in a direct fight.

This comparison between plane only make sense if you compare in a vacuum. Once you factor in supporting assets (favor US) and missile quality (China) things will be different. At minimum, you need to factor in the weapon quality because they need something to shoot with. Whatever earlier J-20 has less than F-22, the PL-16 vs AIM-120 gap will make up for it.

Think supporting assets favor China now.

Just a nice image of a J-20A.

How is the US ahead in EW? And what's "ground observation stuff"? They have like 150 Growlers and few dedicated EW C-130s. Also a lot of pods... In addition these, the F-35s are very potent in higher bands and they have 700+ of that. Ground observation stuff are basically ISR aircraft. The US...
