I am not showing any arrogance to anyone, nor am i laughing on U.S or what ever you are taking it. F-15 or 16 etc they do get updated from time to time. For instance, just recently in 2013 the USAF contracted for the Defensive Management System Modernization program to replace the antenna system and other electronics to increase the B-2's frequency awareness. And other planes are also updated with time.
But when you make a new fighter then its way more suitable to current time as compared to updated one. In a lot of aspects. And what i am trying to say here is that U.S is currently only testing F-35, while on other hand Russia is testing Mig-35, Su-35 and Pak-FA, and china is testing J-10B, J-16,J-15, J-20 and J-31. And its the same story in other fields of military.
My whole point is China is advancing much more rapidly then any country. You can call this arrogance or what ever you want to call it. You might disagree, doesn't mean its arrogance or something.
lol, that's where you were wrong.
Technology advance does not equate to how many type of fighter aircraft you induce over a period of time. It's not like since you bring out the J,1,2,3,4,5,6,7,8,9,10,11,12 and you are seen as more advance or catching up to the country that only bring out the F-35.
The fact is, only what replace what is counted.
In military Aviation, you have several different tyupe of fighter aircraft. And you have to look at what they are replaced with original to see the different. The catagory is as follow
Air Superiority Fighter
Multi-role Fighter
Ground Support Fighter
Naval Fighter
If you have to compare what replace with what, you can only compare between what and what
for China
Air Superiority Fighter - SU-27/J-11 -> J-20 (IP - 2018)
Multi-role Fighter - J-10 .> J-10B
Ground Support Fighter - Q-5 -> J-16
Naval Aviation - Nil -> J-15
for USA
Air Superiority Fighter - F-15C/F-22 -> F-XX (6th Gen) (IP- 2030)
Multi-role Fighter - F-16 -> F-35A
Ground Support Fighter - A-10A -> F-15E/SE
Naval Aviation - F-18E/F -> F-35C
VTOL fighter - AV-8B -> F-35B
The fact is, US only have the one type of fighter coming out to replace them all does not mean they are anything behind or rolling backward. Infact this is where fighter aircraft should go. 40 years ago, we have the same stuff as in China doing now, we have F-4,F-14, F-15,F-16, F-18 using in tri-service (Air Foprce-Navy-Marine) but after 2014, we will only have 2 service fighter aircraft F-22/F-35 plus supporting F-15E/SE. This is infact the best thing American can do, as they simplified to a single or duo fighter, it simply logistic and maintanence facilities, now we order one replacement parts instead of 4, yet that one part can goes to 3 different aircraft that perform different function.
If Chinese are smart, they will do what the US do and trying to dedicate into a single or duo fighter, hence i don't consider building a single fighter have any technological lacking.
And you seems to underestimate the US fighter Tech a lot, we are currently the only one fielded 5th Gen Aircraft, and we are currently the only one out there building a 6th Gen Phototype, to be complete in 2025. By 2025, China would still be half way over their 5th Gen fielding. but we are already doing the total 5th Gen fielding now, infact, it had already started for 7 years now. We are already getting pass 100th mark

while the Chinese have 3 or 4 J-20 in flight testing and 1 or 2 J-31 for flight testing.
