tanlixiang28776..No. China's budget is still tiny compared to America and they have problems producing planes they already have.
No. The Budget has 2 parts, one is to be spent and being spent on the current Armed Force active weapons/systems/planes and vice versa, the other one is the developmental, experimental/R&D. If you put that into account Chinese real budget is larger. Chinese is not engaged with any other nation in conflict/war where it has to spend $400M or more naturally US budget is larger because of the global ambitions and globally forces stationed in nations like S.Korea, Japan, Philippines, Germany, Afghanistan, Kuwait, Saudi Arabia and rest..Obviously you didn't do your home work before explaining why the budget is large.
May i remind you of the massive projects taking air force/navy in consideration J-11B/BS/J-16/J-20/JH-7A, JH7B, J-10B, L15 etc you think you can run all these project without taking into account SAMS/ICBMs etc costs $72-76B? Do you know what was UKs defense budget in 1998? it was around $36 Billion do you honestly believe China's Defense budget is 60-76B, No it's not its much higher considering the massive number of investment R&D and projects.
