Numbers dont matter in the air but the quality of training and equipment matters.PLAAF is way behind IAF in quality of training and equipment.
I'll say what everyone else is thinking, don't get raged ladies and gentlemen...
China has about 2000+ combat aircrafts
India has about 1000 give or take...
Numbers going to 2:1:0 ratio in favor of China, but we don't know what they really have compared to India Sukhoi MKI aircrafts..(See I'm not biased towards any particular country
..) But this also goes down to who are better fighter pilots, India as of course been trained by U.S Topgun, and Israeli Topgun, so overall with the best Fighter experience goes to them... Going to the MRCA deal, I highly doubt India will go for our F-16 Viper, and F-18 S/H we are going to get snubbed... They're going to go with the their Russian Counter-parts...
Well I just made a Useless wall of Text...
Inconclusion, I don't care because
> India, China Together :O...
U.S Airforce Combat aircraft: 5,200, 2,200+ combat aircraft..
U.S Navy Combat Aircraft: 3,700+
(I won't include adding of 400-500 F-35 Lightning II in the mix...)
