JF-17 - production and induction will continue and Pakistan will slowly gain a larger portion of manufacturing. It is widely believed and highly likely (due to various PAF claims) that later versions of the JF-17 will be upgraded, possibly after the first 50. A new Chinese engine, Western avionics, more hardpoints, some minor IR signature and RCS reduction etc. are all possible and likely improvements. A total of 250 will supposedly be inducted in the end, 150 of which have currently been ordered.
An Infra-Red Search and Track system also to be fitted
AWACS
3 SAAB 2000 Erieye AEW&C Systems - 1 trainer has already been delivered, but actual AWAC delivery is listed as 2009/2010, so we should be getting our first anytime now, if at all. Also, we reduced the total number being acquired to make room for Chinese AWAC systems, so the number could fall further.
I'm pretty sure that's 4 Erieye-equipped Saab 2000 AEWC plus the 1 trainer aircraft, 5 Saab 2000 total.
Aerial Refuellers
4 Il-78MP - 2 have already been delivered, the other 2 are expected 2009-2011.
Not sure about this one, some sources (including the inside guys over at PakDef.info) say the delivered aircraft were on temporary lease and have returned to Ukraine. Might want to add a small note about that.
Trainers
K-8 Karakorum - Acquisition and induction will continue. Pakistan was previously supposed to produce these, but now they will be buy them from the Chinese to make room for JF-17 manufacturing in Pakistan. Therefore, I expect we will now induct fewer than 60, as was previously thought.
I'd expect more deliveries for replacing the T-37 and FT-5.
Pakistan Air Force is always on the lookout for cheap Mirages. Some say that UAE Mirage-2000s will be made available to the PAF, and given our history with Mirages, we might seriously consider them for a med-tech role. This I deem to be a credible rumor, if the price is right.
Not credible in my opinion, PAF are serious about the JF, FC-20 and F-16. Not a lot of room left, lets be honest. Those M2k will always be too expensive, especially compared to upgraded F-16. They are nothing like the Mirage III.
It is also likely that some further design work on the JF-17 might take place in Pakistan. This topic is not widely debated, but I think that once we've produced a good amount, we'll try to tinker with it a bit, just as we did with our Mirages.
Avionics certainly, but anything to the airframe would most likely require consultancy from the Chinese. Unless you mean stuff that is already factored in, like aerial refuelling probes and so on.
