Like @ougoah has said, yes ofc they exist. It's also irrelevant to what I originally said, which is that your development time and manufacturing capability are still unsolved issues that hamper any kind of modern tech developments. Same goes for the J-20 development, it's irrelevant to the topic and you're clearly ignorant on its coming development (twin seat, tvc, ws-15).
Going back to the topic, please explain to me how 2035 time window is a bad prediction, given how much time it take for the russian nowadays to develop their new fighters? Where's the lie when I say that even after you develop these nice techs, you still can't afford or even simply can't make them in a substantial numbers?
Well not gonna lie the Su-70 for me was considered a very complex aviation project, Neuron, bae taranis or even the X-47B which were developed earlier still don't have production dates AFAIK when I last checked. The Su-70 is the newest of those 3 and is given a production date in 2024(assuming there are no delays) and has tested fired air to ground weapons, hell it even fired air to air missiles which I cant say the same for the other 3, Also the drone is freaking huge. The funny part was back at key aero I was the only user that was talking about the drone getting an air to air role, no one of course believed me(makes sense considering the aerodynamics favor air to ground missiions and the roles of the other 3 stealth UAVs) than with a stroke of luck they gave that drone an air to air role.
I have not seen anything introduced from the Chinese side like photonic radar antennas like how VEGA introduced to the public, etc, etc. Economy is important but after Nordstream 2 and some arctic oil projects the political climate will more than likely change back. If they are still kicking the shit out of the west with technology
tanks and other shit than their only concern is just to climb back up. For China it is a little bit different it has a high GDP an all but considering the top universities of the U.S. among other international competitions those excellents minds leave their homeland for the U.S. which with along the western side of Europe is becoming a degenerate cesspool drawing in low IQ illegal migrants and teaching kids about 76 genders and LGBT history. The Chinese despite having a great GDP and all that with a nice high IQ population they suffer from impoverishment and studies generally show in the U.S. that even though Asians always score higher SAT scores a white Caucasian with a little more wealth does better in those scores than an Asian from a poor family. Russia is somewhere in the middle but they clearly have plans to still further grow economically and it doesn't look like they have lost their military technological edge either based on the sources I get from good old Russia defense net. I will only pay attention to Chinese military technology, 6th gens or whatever depending how the quality of life has improved for their population.
it actually plays a lot into long-term strategy. If they somehow manage to manufacture a cheap 5th-gen-equivalent they can shut out not just Americans but potentially China as well.
any NATO member purchasing this will get their ass sanctioned so their goes the majority of customers. Japan with some disputes with island ownership is a no. Arab oil countries which have grown and prospered from U.S. military involvement might be a no. So that leaves barely anyone willing to purchase their things in general anyways.
