JF-17 fits the needs of many airforces around the world and it is quite futuristic since PAF will keep evolving this platform/system with new avionics, engines, systems, weapons and even airframe. The main charm of JF-17 is not its price but what it has to offer at this price and upgradability. Price is very good but used aircrafts from other airforces can be purchased at much cheaper price in bulk but they have no future...4-5 yrs okay but beyond that none. JF-17 is a platform to stay for 20 yrs or more with updates.
