And still some online who are too academic about the whole process or too eager to downplay China's MIC achievements will not even entertain the idea that everything being shown is following the rule that nothing that is truly leading edge that China's working on is ever shown hence everything we see is from many, many years ago.
PL-15E used to shoot down French Rafales had retrieved missile wreckage showing they were made in 2012 iirc, many years before people were comfortable admitting PL-15 was in mass production.
PL-15 production apparently has already stopped because it's now 2 generations old for China. The USAF hasn't even yet fielded an equivalent AAM that is as advanced as PL-15 according to the US itself. That would be the AIM-260. China has already stopped producing this level of missile. Let that sink in for a moment and then apply your thoughts to the hypersonic gliders and cruise missiles we are being shown. It is still the same old China, play your fourth best, show your third best and have two higher tiers at the ready. The US used to operate similarly back when it was fit during the Cold War. It's since become an India, bragging about stuff they only started working on. At least they're not like India, bragging about PPT drafts.
