Would the JF-17 block I be upgraded to block II during the overhaul process ?
There are only 3 specified changes in Blk II vs Blk I, according to official PaF source in an interview to AFM. Oxygen supply improvement , IFR capability built in from the onset, and extended weapons integration. Everything else is the same, so there ia not much of a difference. BLK 2 is just a more mature platform. Until the official confirmation of the upgrade, my guess is just as good as any body's. but i think it would be more economical and practical to undertake a Mid Life upgrade kind schedule, some years later down the line, when both Blk I & II are upgraded to the eventual Blk III standard. Block 3 is the holy grail for this line up. A majore upgrade that is.
