the confusion here seems to be over the word upgrade.One can upgrade a radar without total replacement of the radarupgrade
ŭp′grād″
intransitive verb
- To raise to a higher grade or standard.
- To replace (a software program) with a more recently released, enhanced version.
- To replace (a hardware device) with one that provides better performance.
Upgrade is a very broad term. and by the first definition these aircraft are routinely upgraded. to include the new missiles that were mentioned meant the aircraft systems had to be upgraded to add the missile's capability.
F-16s get upgraded all the time to the point where there are several different sets of acroynyms being applied, and this is without counting the standard upgrades they get with things like software patches.
trying to have it both ways. on one side its "we can't judge an aircraft just because it has the latest and most sophisticated feature" on the other side the F-22 is old and the US is hoping to delay a Taiwan invasion!
please use your own definition of "context" The B-2 is 1980s tech but China has no equivalent to the B-2. The F-22 has far more sophisticated engines than J-20. One of the marks of the "LM marketing term generation" is not just that they have sophisticated electronics, but how those electronics interact and work in synergy to create situation awareness and ISR from the pilot all the way to the Generals to all the other weapon systems in the area land, sea, and air. The latest F-18C hornet upgrade have GaN AESA. that doesn't mean that now an F-18 is more advanced than an F-22.
You may have to kind of create a set standard. even the very unique situation of Taiwan creates an extremely complicated warplan that is not at all a matter of "the J-20 has better radar so now the American's are scared" The Japanese had better aircraft than the Americans at the start of world war II and the US adapted tactics to defeat them, along with thousands of other things that lead to victory over Japan, from ball bearings to Submarines. the assessment today would be "Japan has the zero, and the US is toast" not even close. and we don't even know if the J-20 is a "zero" Experience matters. When was the last time the Chinese did a full blown coordinated aerial attack on an Integrated air defense system? Ukraine has proven that war is unpredictable. Easy targets are not always easy, and a lack of experience carries a steep learning curve. Simulations were saying Kiev was supposed to fall in 48 hours. its been over a year now.
I don't think we should underestimate China, but I think we should realistically assess their capabilities and understand their tactical challenges and limitations even they know they have a long way to go, and they do. There are so many different ways to make China miserable, and they are not all from the United States either (india can do a number on them) The most helpful thing that China has done is scared the hell out of their neighbors and unite them against China. China is under the false impression that if the US is removed everyone will become their new best friends, not at all the case. Even a lot of Americans are making the mistake of assessing US Vs China, as opposed to US+allies Vs China. US+allies changes the picture enormously, and even if one says "Well we aren't a US ally!" fine, but many are no friends of china either
