Some artistic illustrations on exploring how the J-36 may be armed in the future, with the possibility of dual-stacking the AAMs inside the J-36's main IWB. Posted by @Hurin92 on Twitter.

If this arrangement is possible, then a max loadout of 8x PL-17s and 6x PL-15s should be viable (or perhaps swapping the PL-15s with 12x tandemly-arranged micro-AAMs for self-defense).

Looks wildly optimistic tbh, this model is fuelless.
I doubt there's going to be more than one "layer", precisely because it's a2a aircraft first.

I think a realistic max loadout for the J-36 is something like 6x PL-17 and 4x PL-15.
Minimum 2x PL-17+4x PL-15. Depending how deep the bays are it can carry another 2x PL-17.

Max load out IMO is 4x PL-17 and 4x PL-15 with the PL-17 stacked on top of each other.

Been thinking about this today.

So now that J-36's basic dimension is available for all to see, USAF can pretty much put in some very educated guesses on things like top speed, weapon payload, radar size, power generation, range and stealth.

Since this is US military we are talking about, they will want to make sure NGAD system's mother ship (the manned fighter) will have to have specs that can overcome the challenges posed by J-36. J-36's threat to things like tankers, AEWC&C, aircraft carriers, B-21 and Guam are pretty obvious. Just as an example, if you see the power cooling issues with F-35 and don't want to lose out to J-36 in electronics, then you will obviously need to ensure you have enough interior space and power generation to overcome J-36's power generation. That alone would yield the need for probably even larger aircraft than J-36 that can fly even faster and farther than J-36.

So, it would take imo 2 years to settle on requirement and pick the winner.

It took 5 years for the first F-22 prototype to fly after Lockmart was picked. It took F-15 3 years to do the same. Let's say NGAD moves faster than F-22 and flies 4 years after a winner is picked, that would still mean 2030 for first flight of an actual prototype.

It took 4 years for F-15 to enter service after it flew. It took 8 years for F-22 to enter service after it first flew.

Now given the complexity of today's systems, It's hard for me to see NGAD taking just 4 years to go from first flight to service entrance. As such, I think it achieves IOC after 2035, probably 2037 to 2038 range.

Whereas I think J-36 will be more around 2031 to 2032. That's a huge period where China has obvious generation gap vs rest of the world.
F-35 have not even ended its systems checklist....service entrance in 2015-2016 and first prototype flight in 2006.

20 years and it don't have all its capabilities and have not overcome its shortfall.

If they don't have something already in the hangar, I cannot see them achieving it before 2040 for a steady working system even if they push hard for it.

B-21 morphing into a loitering AAM turret is their best counter for the 2030s. J-36 is clearly pulling the carpet under their feet.

So that basically means all current specs for NGAD manned fighter will be overthrown and the whole project will be redesigned? It is very interesting to see if it is becoming a trijet just like j36, since xa100 and xa102 are similar in thrust compared to f119/f135, so twin engine configuration cannot match j36’s power generation capability

Potentially yes.

The J-36 poses an even bigger problem to a manned NGAD in US strategy.

The USAF assumption is that they can operate a manned NGAD from Guam because it is too far away for Chinese aircraft to establish air superiority.

But now, we can expect the J-36 to go into service sooner than NGAD, and also to appear in significant numbers over Guam in the 2IC.

So Guam will face the same situation as in the 1IC, where China will have a large advantage in available airbases and aircraft. That means Chinese air and maritime superiority, and the ability to impose a blockade over all of the 1IC and 2IC.

Does it even make sense anymore to go with a large twin-engine NGAD, if there are no "safe" rear areas bases like Guam?

Are they now better off with a single engine design for operations in the 1IC, given that all the airbases in the 1IC and 2IC will be under attack anyway?

Could they try operating from safe rear areas bases in the 3IC?

Potentially, but a supersonic air superiority aircraft would have to be larger than a B-21 and presumably need 4+ engines. Is that even affordable, given the current NGAD experience? Mission flight durations would also be over 14 hours to reach China and back.

Eh, I think in the simplest terms the best gauge for how quickly the US can keep pace depends on where they are with component technologies and subsystems, especially in the cost performance dimension. If they’re at parity or ahead their pace is purely dictated by organizational questions. If they’re behind on the component tech then their schedule worsens considerably.
I was going to respond the same. One can argue that the U.S. can build a similar plane as the J-36, but having the tech to build one that will have a decisive advantage over the J-36, especially in a network environment is doubtful. If we were to start a project to end up with a similar plane but ten years later would not be very useful. The most likely case is a lot of hand wringing and nothing concrete for years, maybe a decade to come. The longer this goes on, more synergy like the electronics, EVs, C-919 etc. will tilt the cost structure more in favor of China. If in ten years, we can build a plane for three times the Chinese one, I don't know how meaningful that would be.

actually, just thought about this more. I think I might be underestimating the testing period.

The demand on these 6th generation aircraft in terms of EW, sensor fusion, command and control is so high. Just thinking about EW, it would have to deal with not just aerial targets, but also different types of ships and ground air defense/radar. + also satellites and other sources which might be used to confuse adversaries.

While you can test these system on specialized aircraft, they will eventually need to be verified on the 6th gen aircraft also. And these testing will last for a while.

so getting J-36 into service by 2032 would actually be quite impressive. I wouldn't be surprised if NGAD doesn't achieve IOC until 2040.
Maybe unpopular opinion:The primary reason for the prolonged development cycles of new weapons like the F-22 and F-35 in the U.S. military post-Cold War is the lack of pressure from peer competitors.

It's important to note that the U.S. military's air superiority has remained unchallenged since the end of World War II (even the German jet aircraft during WWII did not exert significant competitive pressure on the U.S. due to insufficient production numbers). Broadly speaking, since the Wright brothers invented the airplane, Americans have consistently held a dominant position in the field of aviation. This is the first time that Americans have lost this crown.

Therefore, it is reasonable to anticipate that we will witness a swift response from the U.S. military (in panic): perhaps expediting new tests and modifications on the already test-flown NGAD (though this is uncertain) to quickly propose a new solution ( with minor differences) for production. Or, they might take a bit longer to introduce a more competitive new design.

Regardless, we are on the brink of a new arms race in this century. While this may be detrimental to the world at large, But for us military enthusiasts, it presents an unprecedented opportunity.

I doubt they will.
Such a plane now seems to be like third priority for US.

They can if digital century will work out, but otherwise NGAD ecosystem (with lightweight manned component) and F/A-XX to tilt decks towards great power competition take priority.

Personal expectation - J-36 will remain as a unique PLAAF capability for a while.
Maybe Russia later in the next decade.

Ironically, f-35 now lacks key a2g capabilities above all else, making it incomplete in precisely the types of activities it must do. Munitions integration, laggard EOTS, lack of it's integration into sf...
In a2a domain current fleet is up to standard, at least until future is taken into account.

The Chinese had the J-20 and is getting ready to field the J-35. Given that the U.S. is always used to having a generational advantage over its competitors, how would that not exert competitive pressure for the U.S.? The deindustrialization for the last four decades have changed the U.S. and not for the better. You can dream up a lot of ideas, but to bring them to fruition requires the support of the industrial eco-web that no longer exist in the U.S. to the same degree as before. China has a much, much stronger industrial eco-system to draw from.

However, I don't believe it will take that long (though the budget will undoubtedly be larger).Maybe achieves IOC on 2032-35.
