Unless you know precisely what occurred there, dont come to conclusions. Some folks destroyed the entire fleet, where is their claim now?
On topic, AVM shahid latif clearly mentioned in his interview to Usman Shabir that RCS reduction, IFR, IRST, an AESA radar and payload increase are planned for future batches. Upgrades were planned after every five years.
If folks don't believe SecDEF public statement in parliament open session, then we can only say "sum'mun bukmun umyun"
On topic, IRST, an AESA radar and payload increase are planned for future batches requires a better engine. PAF is sticking to RD-93 as per JF-17 project director. So IFR is only thing happening in Block 2.
Now Block 3 remains, which may commence in mid to late 2016, If by then funding crunch disappears and a better engine is procured, we can see wishlist turning into reality, because structural changes are required to put extra hard point on JF-17 and to PUT AESA, IRST we require both funds and better engine and how things going now, this funding crunch will remain due to WoT and bad economic situation for at least 5-6 years
What AVM Shahid Lateef said is not "Pathar par lakeer" because funds were available at that time, which has disappeared now and this is the reason third squadron hasn't been raised so far.
So It's better to talk by taking things in to perspective instead of being adamant on what some
"official" said in yester year.
Instead of basing claims on your some retired AVM , it's better to read this year articles of JF-17 project director and PAC head which clearly hints the slowing down of JF-17 program so far.
Ive got it from the man holding the plaque.. The rest is sure.. due time.
