Such future projections are always tricky, to say the least. Next to impossible to do right would be closer to truth, really. But let me try. I'll skip the ground forces bit as it's too much work and i don't have enough knowledge about those production capabilites anyway.
Airplanes wise - at least some 350 j10 or j9s could be produced by the end of 2010. I've taken into consideration that there already are some 40 j10 and j9s (combined) available and assumed that multiple production lines could churn out around 6 planes per month.
150 more jh7s would not be out of the question either.
A fleet of 4 kj2000 EW planes and 8-12 y8 'balance beam' EW planes could/should be operational under current plans anyway. It's next to impossible to know how many more china would make if it was preparing for a war in 2010.
It is always possible to buy foreign (russian probably, since itd be on short notice) equipment. If you're preparing for war, you'll get pretty much all they money you ask. Defence budget would/could balloon 1000 % and still be sustained on a short term (5 years) basis. Of course, such an action would be greatly frowned upon by the international community and would make potential chinese enemies also go into a weapons shopping spree, probably with great discounts given by US if they buy their equipment.
Ships would probably include 3 more type 93 subs, 3-4 more yuans and something like 8-10 more songs. Yes, i'm pulling all of these figures out of my ass, just doing guesstimates. Yeah, and those ordered 8 improved kilos would all be delivered by then.
With surface ships its a little bit more exact since theyre all built out in the open, easier to tell capacities china has to build 'em in the first place. up to 2 51c and 2 more 52c destroyers might be built and delivered by then. something like 8 more type 54 frigates could be build too. And those 2 improved sovremenies would be put in service as well. Fast attack boats...um.... i'll say 20-30 more, if more shipyards are put into action. And so on. It's really kinda pointless, all this. Since for such short notice china would be better off buying stuff from others, and the increased production is hard to determine anyway, who knows how many more production lines could open?
